	rng: restrict passthrough names to known-good files
	There is some controversy[1] on the qemu list on whether qemu should
	have ever allowed arbitrary file name passthrough, or whether it
	should be restricted to JUST /dev/random and /dev/hwrng.  It is
	always easier to add support for additional filenames than it is
	to remove support for something once released, so this patch
	restricts libvirt 1.0.3 (where the virtio-random backend was first
	supported) to just the two uncontroversial names, letting us defer
	to a later date any decision on whether supporting arbitrary files
	makes sense. Additionally, since qemu 1.4 does NOT support
	/dev/fdset/nnn fd passthrough for the backend, limiting to just
	two known names means that we don't get tempted to try fd
	passthrough where it won't work.

	libvirt does not logout of iscsi targets, causing system hang on shutdown
	There's a quite old bug entry here:

	https://bugzilla.redhat.com/show_bug.cgi?id=700010

	I just stumbled over that very issue on F18. Doing a little bit
	debugging of the shutdown sequence, it turns out that - at least on my
	F18 installation - libvirtd is shutdown *after* iscsid, which makes it
	impossible for libvirt to perform the logout of the iscsi session properly.

	This patch simply adds another startup dependancy on iscsid.service
	which in turn delays iscsid shutdown until after libvirtd has stopped.
	Having that applied, the system shuts down properly again.

	qemu: Use -1 as unpriviledged uid/gid
	Commit f506a4c1 changed virSetUIDGID() to be a noop
	when uid/gid are -1, while it used to be a noop when
	they are <= 0.

	The changes in this commit broke creating new VMs in GNOME Boxes
	as qemuDomainCheckDiskPresence gets called during domain creation/startup,
	which in turn calls virFileAccessibleAs which fails after calling
	virSetUIDGID(0, 0) (Boxes uses session libvirtd). virSetUIDGID is called with
	(0, 0) as these are the default user/group values in virQEMUDriverConfig
	for session libvirtd.

	This commit changes virQEMUDriverConfigNew to use -1 as the unpriviledged
	uid/gid. I've also looked at the various places where cfg->user is used,
	and they all seem to handle -1 correctly.

	virnetdevmacvlan.c: Introduce mutex for macvlan creation
	Currently, after we removed the qemu driver lock, it may happen
	that two or more threads will start up a machine with macvlan and
	race over virNetDevMacVLanCreateWithVPortProfile(). However,
	there's a racy section in which we are generating a sequence of
	possible device names and detecting if they exits. If we found
	one which doesn't we try to create a device with that name.
	However, the other thread is doing just the same. Assume it will
	succeed and we must therefore fail. If this happens more than 5
	times (which in massive parallel startup surely will) we return
	-1 without any error reported. This patch is a simple hack to
	both of these problems. It introduces a mutex, so only one thread
	will enter the section, and if it runs out of possibilities,
	error is reported. Moreover, the number of retries is raised to 20.

	    qemu: Avoid deadlock in autodestroy

	since we now have a fix which avoids the deadlock scenario
	entirely

2013-03-01  Daniel P. Berrange  <berrange@redhat.com>

	Fix deadlock in QEMU close callback APIs
	There is a lock ordering problem in the QEMU close callback
	APIs.

	When starting a guest we have a lock on the VM. We then
	set a autodestroy callback, which acquires a lock on the
	close callbacks.

	When running auto-destroy, we obtain a lock on the close
	callbacks, then run each callbacks - which obtains a lock
	on the VM.

	This causes deadlock if anyone tries to start a VM, while
	autodestroy is taking place.

	The fix is to do autodestroy in 2 phases. First obtain
	all the callbacks and remove them from the list under
	the close callback lock. Then invoke each callback
	from outside the close callback lock.

	Fix crash in QEMU auto-destroy with transient guests
	When the auto-destroy callback runs it is supposed to return
	NULL if the virDomainObjPtr is no longer valid. It was not
	doing this for transient guests, so we tried to virObjectUnlock
	a mutex which had been freed. This often led to a crash.

	    qemu: Avoid deadlock in autodestroy

2013-02-28  Eric Blake  <eblake@redhat.com>

	qemu: -numa doesn't (yet) support disjoint range
	https://bugzilla.redhat.com/show_bug.cgi?id=896092 mentions that
	qemu 1.4 and earlier only accept a simple start-stop range for
	the cpu=... argument of -numa.  Libvirt would attempt to use
	-numa cpu=1,3 for a disjoint range, which did not work as intended.

	Upstream qemu will be adding a new syntax for disjoint cpu ranges
	in 1.5; but the design for that syntax is still under discussion
	at the time of this patch.  So for libvirt 1.0.3, it is safest to
	just reject attempts to build an invalid qemu command line; in the
	future, we can add a capability bit and translate to the final
	accepted design for selecting a disjoint cpu range in numa.

	On a machine without yajl headers, I was seeing random segfaults
	from qemumonitorjsontest (about 90% of the runs on my particular

	points to a case of a race leading to unreferencing a stale
	pointer to an object that had already been freed.  I also noticed
	that if I got the segfault, I was seeing messages such as:

	2013-02-22 16:12:37.504+0000: 19833: error : virNetSocketWriteWire:1361 : Cannot write data: Bad file descriptor

	which is also evidence of deferencing a stale pointer.  I traced it
	to a race where qemuMonitorTestIO could execute late, after the
	main thread had already called qemuMonitorTestFree and called
	virNetSocketClose(test->client) but not clearing it out to NULL.
	Sure enough, after test->client has been closed, fd is -1, which
	causes an attempt to write to the socket to fail, which in turn
	triggers the error code of qemuMonitorTestIO that tries to re-close
	test->client.

	qemu: minor monitor lock cleanups
	If virCondInit fails (okay, so that's unlikely), then we end up
	attempting a virObjectUnlock() on the cleanup path, even though
	we don't hold a lock.  This is not guaranteed to be safe.  While
	at it, I noticed a couple places where we were referencing mon->fd
	outside locks.

	* src/qemu/qemu_monitor.c (qemuMonitorOpenInternal): Minimize lock
	duration.  mon->watch doesn't need clean up on error.
	(qemuMonitorGetBlockExtent, qemuMonitorBlockResize): Don't
	dereference fd outside of lock.

	qemu: don't override earlier json error
	I built without yajl support, and noticed a strange failure message
	in qemumonitorjsontest:

	2013-02-22 16:12:37.503+0000: 19812: error : virJSONValueToString:1119 : internal error No JSON parser implementation is available
	2013-02-22 16:12:37.503+0000: 19812: error : qemuMonitorJSONCommandWithFd:253 : out of memory

	While a later patch will fix the test to skip when json is not present,
	this patch avoids overriding the more useful error message from
	virJSONValueToString returning NULL.

	use client id for IPv6 DHCP host definition
	Originally, only a host name was used to associate a
	DHCPv6 request with a specific IPv6 address.  Further testing
	demonstrates that this is an unreliable method and, instead,
	a client-id or DUID needs to be used.  According to DHCPv6
	standards, this id can be a duid-LLT, duid-LL, or duid-UUID
	even though dnsmasq will accept almost any text string.

	Although validity checking of a specified string makes sure it is
	hexadecimal notation with bytes separated by colons, there is no
	rigorous check to make sure it meets the standard.

	Documentation and schemas have been updated.

	qemu_migration: Cancel running jobs on failed migration
	If a migration fails, we need to stop all block jobs running so
	qemu doesn't try to send data to destination over and over again.

	qemu_migration: Stop NBD server at Finish phase
	At the end of migration, it is important to stop NBD
	server and thus release all allocated resources.

2013-02-23  Michal Privoznik  <mprivozn@redhat.com>

	qemu_migration: Introduce qemuMigrationDriveMirror
	This function does the source part of NBD magic. It
	invokes drive-mirror on each non shared and RW disk with
	a source and wait till the mirroring process completes.
	When it does we can proceed with migration.

	Currently, an active waiting is done: every 500ms libvirt
	asks qemu if block-job is finished or not.  However, once
	the job finishes, qemu doesn't report its progress so we
	can only assume if the job finished successfully or not.
	The better solution would be to listen to the event which
	is sent as soon as the job finishes. The event does
	contain the result of job.

2013-02-23  Michal Privoznik  <mprivozn@redhat.com>

	qemu_migration: Introduce qemuMigrationStartNBDServer()
	We need to start NBD server and feed it with all non-<shared/>,
	RW and source-full disks. Moreover, with new virPortAllocator we
	must ensure the borrowed port for NBD server will be returned if
	either migration completes or qemu process is torn down.

	qemu: Introduce nbd-server-stop command
	This will be used after all migration work is done
	to stop NBD server running on destination.  It
	doesn't take any arguments, just issues a command.

	qemu: Introduce nbd-server-add command
	This will be used with new migration scheme.
	This patch creates basically just monitor stub
	functions. Wiring them into something useful
	is done in later patches.

	qemu: Introduce nbd-server-start command
	This will be used with new migration scheme.
	This patch creates basically just monitor stub
	functions. Wiring them into something useful

	Introduce NBD migration cookie
	This migration cookie is meant for two purposes. The first is to be sent
	in begin phase from source to destination to let it know we support new
	implementation of VIR_MIGRATE_NON_SHARED_{DISK,INC} so destination can
	start NBD server. Then, the second purpose is, destination can let us
	know, on which port the NBD server is running.

	qemu: Introduce NBD_SERVER capability
	This just keeps track whether qemu knows nbd-server-* commands
	so we can use it during migration or not.

	The bfree and blocks fields are supposed to be in units of frsize.  We were

	qemu: Remove the shared disk entry if the operation is ejecting or updating
	For both AttachDevice and UpdateDevice APIs, if the disk device
	is 'cdrom' or 'floppy', the operations could be ejecting, updating,
	and inserting. For either ejecting or updating, the shared disk
	entry of the original disk src has to be removed, because it's
	not useful anymore.

	And since the original disk def will be changed, new disk def passed
	as argument will be free'ed in qemuDomainChangeEjectableMedia, so
	we need to copy the orignal disk def before
	qemuDomainChangeEjectableMedia, to use it for qemuRemoveSharedDisk.

2013-02-21  Osier Yang  <jyang@redhat.com>

	qemu: Move the shared disk adding and sgio setting prior to attaching
	The disk def could be free'ed by qemuDomainChangeEjectableMedia,
	which can thus cause crash if we reference the disk pointer. On
	the other hand, we have to remove the added shared disk entry from
	the table on error codepath.

	qemu: Update shared disk table when reconnecting qemu process

	qemu: Record names of domain which uses the shared disk in hash table
	The hash entry is changed from "ref" to {ref, @domains}. With this, the
	caller can simply call qemuRemoveSharedDisk, without afraid of removing
	the entry belongs to other domains. qemuProcessStart will obviously
	benifit from it on error codepath (which calls qemuProcessStop to do
	the cleanup).

	qemu: Merge qemuCheckSharedDisk into qemuAddSharedDisk
	Based on moving various checking into qemuAddSharedDisk, this
	avoids the caller using it in wrong ways. Also this adds two
	new checking for qemuCheckSharedDisk (disk device not 'lun'
	and kernel doesn't support unpriv_sgio simply returns 0).

	qemu: Use atomic ops for driver->nactive

2013-02-19  Jiri Denemark  <jdenemar@redhat.com>

	rpc: Avoid deadlock when closing client connection
	We need to drop the server lock before calling virObjectUnlock(client)
	since in case we had the last reference to the client, its dispose
	callback would be called and that could possibly try to lock the server
	and cause a deadlock. This is exactly what happens when there is only
	one QEMU domain running and it is marked to be autodestroyed when the
	connection dies. This results in qemuProcessAutoDestroy ->
	qemuProcessStop -> virNetServerRemoveShutdownInhibition call sequence,
	where the last function locks the server.

	Avoid resetting errors in virTypedParamsFree
	The function does not report any errors so there should be no need too
	reset an existing error first. Moreover, virTypedParamsFree is mostly
	called in cleanup phase where it has the potential to reset any useful
	reported earlier.

	build: force correct gcc syntax for attribute_nonnull
	Gcc lets you do:

	int ATTRIBUTE_NONNULL(1) foo(void *param);
	int foo(void *param) ATTRIBUTE_NONNULL(1);
	int ATTRIBUTE_NONNULL(1) foo(void *param) { ... }

	but chokes on:

	int foo(void *param) ATTRIBUTE_NONNULL(1) { ... }

	However, since commit eefb881, we have intentionally been disabling
	ATTRIBUTE_NONNULL because of lame gcc handling of the attribute (that
	is, gcc doesn't do decent warning reporting, then compiles code that
	mysteriously fails if you break the contract of the attribute, which
	is surprisingly easy to do), leaving it on only for Coverity (which
	does a much better job of improved static analysis when the attribute
	is present).

	But completely eliding the macro makes it too easy to write code that
	uses the fourth syntax option, if you aren't using Coverity.  So this
	patch forces us to avoid syntax errors, even when not using the
	attribute under gcc.  It also documents WHY we disable the warning
	under gcc, rather than forcing you to find the commit log.

	* src/internal.h (ATTRIBUTE_NONNULL): Expand to empty attribute,
	rather than nothing, when on gcc.

	Fix libvirt upgrade path when nwfilter is used
	Between revision 65fb9d49 and before this patch, an upgrade of libvirt while
	VMs are running and instantiating iptables filtering rules due to nwfilter
	rules, may leave stray iptables rules behind when shutting VMs down.
	Left-over iptables rules may look like this:

	Chain FP-vnet0 (1 references)
	target     prot opt source               destination         
	DROP       tcp  --  0.0.0.0/0            0.0.0.0/0            tcp spt:122
	ACCEPT     all  --  0.0.0.0/0            0.0.0.0/0           

	[...]

	Chain libvirt-out (1 references)
	target     prot opt source               destination         
	FO-vnet0   all  --  0.0.0.0/0            0.0.0.0/0           [goto]  PHYSDEV match --physdev-out vnet0



	The reason is that the recent nwfilter code only removed filtering rules in
	the libvirt-out chain that contain the --physdev-is-bridged parameter.
	Older rules didn't match and were not removed.

	Note that the user-defined chain FO-vnet0 could not be removed due to the
	reference from the rule in libvirt-out.

	Often the work around may be done through

	service iptables restart
	kill -SIGHUP $(pidof libvirtd)

	This patch now also removes older libvirt versions' iptables rules.

	storage: test backing chain traversal
	Testing our backing chain handling will make it much easier to
	ensure that we avoid issues in the future.  If only I had written
	this test before I first caused several regressions...

	* tests/virstoragetest.c: New test.
	* tests/Makefile.am (test_programs): Build it.
	* .gitignore: Ignore new files.

2013-02-16  Eric Blake  <eblake@redhat.com>

	storage: don't follow backing chain symlinks too eagerly
	If you have a qcow2 file /path1/to/file pointed to by symlink
	/path2/symlink, and pass qemu /path2/symlink, then qemu treats
	a relative backing file in the qcow2 metadata as being relative
	to /path2, not /path1/to.  Yes, this means that it is possible
	to create a qcow2 file where the choice of WHICH directory and
	symlink you access its contents from will then determine WHICH
	backing file (if any) you actually find; the results can be
	rather screwy, but we have to match what qemu does.

	Libvirt and qemu default to creating absolute backing file
	names, so most users don't hit this.  But at least VDSM uses
	symlinks and relative backing names alongside the
	--reuse-external flags to libvirt snapshot operations, with the
	result that libvirt was failing to follow the intended chain of
	backing files, and then backing files were not granted the
	necessary sVirt permissions to be opened by qemu.

	See https://bugzilla.redhat.com/show_bug.cgi?id=903248 for
	more gory details.  This fixes a regression introduced in
	commit 8250783.

	I tested this patch by creating the following chain:

	ls /home/eblake/Downloads/Fedora.iso # raw file for base
	cd /var/lib/libvirt/images
	qemu-img create -f qcow2 \
	  -obacking_file=/home/eblake/Downloads/Fedora.iso,backing_fmt=raw one
	mkdir sub
	cd sub
	ln -s ../one onelink
	qemu-img create -f qcow2 \
	  -obacking_file=../sub/onelink,backing_fmt=qcow2 two
	mv two ..
	ln -s ../two twolink
	qemu-img create -f qcow2 \
	  -obacking_file=../sub/twolink,backing_fmt=qcow2 three
	mv three ..
	ln -s ../three threelink

	then pointing my domain at /var/lib/libvirt/images/sub/threelink.
	Prior to this patch, I got complaints about missing backing
	files; afterwards, I was able to verify that the backing chain
	(and hence DAC and SELinux relabels) of the entire chain worked.

	* src/util/virstoragefile.h (_virStorageFileMetadata): Add
	directory member.
	* src/util/virstoragefile.c (absolutePathFromBaseFile): Drop,
	replaced by...

	(virStorageFileGetMetadataInternal): Add an argument.

	storage: refactor metadata lookup

	  \-> virStorageFileGetMetadataFromFD

	However, a future patch wants to add an additional parameter to
	the bottom of the chain, for use by virStorageFileGetMetadataRecurse,
	without affecting existing external callers.  Since there is only a
	single caller of the internal function, we can repurpose it to fit
	our needs, with this patch giving us:

	external users
	  \-> virStorageFileGetMetadataFromFD
	      \-> virStorageFileGetMetadataInternal
	virStorageFileGetMetadataRecurse /
	  \-> virStorageFileGetMetadataInternal

	vbox: Don't overwrite errors returned by virDomainDeviceDefParse

2013-02-14  Laine Stump  <laine@laine.org>

	util: maintain caps when running command with uid != 0
	virCommand was previously calling virSetUIDGID() to change the uid and
	gid of the child process, then separately calling
	virSetCapabilities(). This did not work if the desired uid was != 0,
	since a setuid to anything other than 0 normally clears all
	capabilities bits.

	The solution is to use the new virSetUIDGIDWithCaps(), sending it the
	uid, gid, and capabilities bits. This will get the new process setup
	properly.

	Since the static functions virSetCapabilities() and
	virClearCapabilities are no longer called, they have been removed.

	NOTE: When combined with "filecap $path-to-qemu sys_rawio", this patch
	will make CAP_SYS_RAWIO (which is required for passthrough of generic
	scsi commands to a guest - see commits e8daeeb, 177db08, 397e6a7, and
	74e0349) be retained by qemu when necessary. Apparently that
	capability has been broken for non-root qemu ever since it was
	originally added.

2013-02-14  Laine Stump  <laine@laine.org>

	util: virSetUIDGIDWithCaps - change uid while keeping caps
	Normally when a process' uid is changed to non-0, all the capabilities
	bits are cleared, even those explicitly set with calls to
	capng_update()/capng_apply() made immediately before setuid. And
	*after* the process' uid has been changed, it no longer has the
	necessary privileges to add capabilities back to the process.

	In order to set a non-0 uid while still maintaining any capabilities
	bits, it is necessary to either call capng_change_id() (which
	unfortunately doesn't currently call initgroups to setup auxiliary
	group membership), or to perform the small amount of calisthenics
	contained in the new utility function virSetUIDGIDWithCaps().

	Another very important difference between the capabilities
	setting/clearing in virSetUIDGIDWithCaps() and virCommand's
	virSetCapabilities() (which it will replace in the next patch) is that
	the new function properly clears the capabilities bounding set, so it
	will not be possible for a child process to set any new
	capabilities.

	A short description of what is done by virSetUIDGIDWithCaps():

	1) clear all capabilities then set all those desired by the caller (in
	capBits) plus CAP_SETGID, CAP_SETUID, and CAP_SETPCAP (which is needed
	to change the capabilities bounding set).

	2) call prctl(), telling it that we want to maintain current
	capabilities across an upcoming setuid().

	3) switch to the new uid/gid

	4) again call prctl(), telling it we will no longer want capabilities
	maintained if this process does another setuid().

	5) clear the capabilities that we added to allow us to
	setuid/setgid/change the bounding set (unless they were also requested
	by the caller via the virCommand API).

	Because the modification/maintaining of capabilities is intermingled
	with setting the uid, this is necessarily done in a single function,
	rather than having two independent functions.

	Note that, due to the way that effective capabilities are computed (at
	time of execve) for a process that has uid != 0, the *file*
	capabilities of the binary being executed must also have the desired
	capabilities bit(s) set (see "man 7 capabilities"). This can be done
	with the "filecap" command. (e.g. "filecap /usr/bin/qemu-kvm sys_rawio").

2013-02-14  Laine Stump  <laine@laine.org>

	util: drop capabilities immediately after changing uid/gid of child
	This is an interim measure to make sure everything still works in this
	order. The next step will be to perform capabilities drop and
	setuid/gid as a single operation (which is the only way to keep any
	capabilities when switching to a non-root uid).

2013-02-14  Laine Stump  <laine@laine.org>

	qemu: let virCommand set child process security labels/uid/gid
	The qemu driver had been calling virSecurityManagerSetProcessLabel()
	from a "pre-exec hook" function that is run after the child is forked,
	but before exec'ing qemu. This is problematic because the uid and gid
	of the child are set by the security driver, but capabilities are
	dropped by virCommand - such separation doesn't work; the two
	operations must be done together or the capabilities do not transfer
	properly to the child process.

	This patch switches to using virSecurityManagerSetChildProcessLabel(),
	which is called prior to virCommandRun() (rather than being called
	*during* virCommandrun() by the hook function), and doesn't set the
	UID/GID/security label directly, but instead merely informs virCommand
	what it should set them all to when the time is appropriate.

	This lets virCommand choose to do the uid/gid and caps dropping all at
	the same time if it wants (it does *want* to, but isn't doing so yet;
	that's for an upcoming patch).

2013-02-14  Laine Stump  <laine@laine.org>

	security: add new virSecurityManagerSetChildProcessLabel API
	The existing virSecurityManagerSetProcessLabel() API is designed so
	that it must be called after forking the child process, but before
	exec'ing the child. Due to the way the virCommand API works, that
	means it needs to be put in a "hook" function that virCommand is told
	to call out to at that time.

	Setting the child process label is a basic enough need when executing
	any process that virCommand should have a method of doing that. But
	virCommand must be told what label to set, and only the security
	driver knows the answer to that question.

	The new virSecurityManagerSet*Child*ProcessLabel() API is the way to
	transfer the knowledge about what label to set from the security
	driver to the virCommand object. It is given a virCommandPtr, and each
	security driver calls the appropriate virCommand* API to tell
	virCommand what to do between fork and exec.

	1) in the case of the DAC security driver, it calls
	virCommandSetUID/GID() to set a uid and gid that must be set for the
	child process.

	2) for the SELinux security driver, it calls
	virCommandSetSELinuxLabel() to save a copy of the char* that will be
	sent to setexeccon_raw() *after forking the child process*.

	3) for the AppArmor security drivers, it calls
	virCommandSetAppArmorProfile() to save a copy of the char* that will
	be sent to aa_change_profile() *after forking the child process*.

	With this new API in place, we will be able to remove
	virSecurityManagerSetProcessLabel() from any virCommand pre-exec
	hooks.

	(Unfortunately, the LXC driver uses clone() rather than virCommand, so
	it can't take advantage of this new security driver API, meaning that
	we need to keep around the older virSecurityManagerSetProcessLabel(),
	at least for now.)

2013-02-14  Laine Stump  <laine@laine.org>

	util: add security label setting to virCommand
	virCommand gets two new APIs: virCommandSetSELinuxLabel() and
	virCommandSetAppArmorProfile(), which both save a copy of a
	null-terminated string in the virCommand. During virCommandRun, if the
	string is non-NULL and we've been compiled with AppArmor and/or
	SELinux security driver support, the appropriate security library
	function is called for the child process, using the string that was
	previously set. In the case of SELinux, setexeccon_raw() is called,
	and for AppArmor, aa_change_profile() is called.

	This functionality has been added so that users of virCommand can use
	the upcoming virSecurityManagerSetChildProcessLabel() prior to running
	a child process, rather than needing to setup a hook function to be
	called (and in turn call virSecurityManagerSetProcessLabel()) *during*
	the setup of the child process.

2013-02-14  Laine Stump  <laine@laine.org>

	build: define SECDRIVER_LIBS in Makefile.am
	This makes it simpler to include the necessary system security driver
	libraries for a particular system. For this patch, several existing
	conditional sections from the Makfile were replaced; I'll later be
	adding SECDRIVER_LIBS to libvirt_util_la_LIBADD, because vircommand.c
	will be calling a function from $securitylib.

	qemu: replace exec hook with virCommandSetUID/GID in storage_backend

	qemu: replace exec hook with virCommandSetUID/GID in qemuCaps*
	Setting the uid/gid of the child process was the only thing done by
	the hook function in this case, and that can now be done more simply
	with virCommandSetUID/GID.

	util: make virSetUIDGID a NOP only when uid or gid is -1
	Rather than treating uid:gid of 0:0 as a NOP, we blindly pass that
	through to the lower layers. However, we *do* check for a requested
	value of "-1" to mean "don't change this setting". setregid() and
	setreuid() already interpret -1 as a NOP, so this is just an
	optimization, but we are also calling getpwuid_r and initgroups, and
	it's unclear what the former would do with a uid of -1.

2013-02-14  Laine Stump  <laine@laine.org>

	util: add virCommandSetUID and virCommandSetGID
	If a uid and/or gid is specified for a command, it will be set just
	after the user-supplied post-fork "hook" function is called.

	The intent is that this can replace user hook functions that set
	uid/gid. This moves the setting of uid/gid and dropping of
	capabilities closer to each other, which is important since the two
	should really be done at the same time (libcapng provides a single
	function that does both, which we will be unable to use, but want to

	util: refactor virCommandHook into virExec and virCommandHandshakeChild

	util: eliminate extra args from virExec
	All args except "cmd" in the call to virExec are now redundant, since
	they can all be found in cmd, so remove the args and reference the
	data directly in cmd. One exception to this is that "infd" was being
	modified within virExec, and modifying the original in cmd caused make
	check failures, so cmd->infd is copied to a local, and the local is
	used during virExec().

2013-02-14  Laine Stump  <laine@laine.org>

	util: eliminate generic hook from virExecWithHook
	virExecWithHook is only called from one place, so it always has the
	same "hook" function (virHookCommand), and the data sent to that
	function is always a virCommandPtr, so eliminate the function and
	generic data from the arglist, and replace it with "virCommandPtr
	cmd". The call to (hook)(data) is replaced with
	"virHookCommand(cmd)". Finally, virExecWithHook is renamed to virExec.

	Indentation has been updated only for code that will remain after the
	next patch, which will remove all other args to virExec (since they
	are now redundant, as they're all members of virCommandPtr).

	Remove qemuDriverLock from almost everywhere
	With the majority of fields in the virQEMUDriverPtr struct
	now immutable or self-locking, there is no need for practically
	any methods to be using the QEMU driver lock. Only a handful
	of helper APIs in qemu_conf.c now need it

	virCommand: Don't misuse the eventloop for async IO
	Currently, if a command wants to do asynchronous IO, a callback
	is registered in the libvirtd eventloop to handle writes and
	reads. However, there's a race in virCommandWait. The eventloop
	may already be executing the callback, while virCommandWait is
	mangling internal state of virCommand. To deal with it, we need
	to either introduce locking or spawn a separate thread where we
	poll() on stdio from child. The former, however, requires to
	unlock all mutexes held, as the event loop may execute other
	callbacks which tries to lock one of the mutexes, deadlock and
	thus never wake us up. So it's safer to spawn a separate thread.

	xen: clean up the mess with cpumap
	Commit 8b55992f added some Coverity comments to silence what was
	a real bug in the code.  Since then, we've had a miserable run
	of trying to fix the underlying problem (commits c059cde and
	ba5193c), and still have a problem on 32-bit machines.

	This fixes the problem for once and for all, by realizing that
	on older xen, cpumap_t is identical to uint64_t, and using the
	new virendian.h to do the transformation from the API (documented
	to be little-endian) to the host structure.

	* src/xen/xen_hypervisor.c (virXen_setvcpumap): Do the conversion
	correctly.  Finally.

	Delete in favor of more generic macros.
	(qcow2GetBackingStoreFormat, qcowXGetBackingStore)
	(qedGetBackingStore, virStorageFileMatchesVersion)
	(virStorageFileGetMetadataInternal): Use new macros.

2013-02-13  Eric Blake  <eblake@redhat.com>

	util: add virendian.h macros
	We have several cases where we need to read endian-dependent
	data regardless of host endianness; rather than open-coding
	these call sites, it will be nicer to funnel things through
	a macro.

	The virendian.h file can be expanded to add writer functions,
	and/or 16-bit access patterns, if needed.  Also, if we need
	to turn things into a function to avoid multiple evaluations
	of buf, that can be done later.  But for now, a macro worked.

	Fix potential deadlock across fork() in QEMU driver
	The hook scripts used by virCommand must be careful wrt
	accessing any mutexes that may have been held by other
	threads in the parent process. With the recent refactoring
	there are 2 potential flaws lurking, which will become real
	deadlock bugs once the global QEMU driver lock is removed.

	Remove use of the QEMU driver lock from the hook function
	by passing in the 'virQEMUDriverConfigPtr' instance directly.

	Add functions to the virSecurityManager to be invoked before
	and after fork, to ensure the mutex is held by the current
	thread. This allows it to be safely used in the hook script
	in the child process.

	parsing, output formatting and range validation for the new
	virDomainDeviceCCWAddress type.

	S390: Documentation for CCW address type
	The native bus for s390 I/O is called CCW (channel command word).
	As QEMU has added basic support for the CCW bus, i.e. the
	ability to assign CCW devnos (bus addresses) to devices.
	Domains with the new machine type s390-ccw-virtio can use the
	CCW bus. Currently QEMU will only allow to define virtio
	devices on the CCW bus.
	Here we add the new machine type and the new device address to the

	virsh: Use virNodeDeviceLookupSCSIHostByWWN
	Only nodedev-destroy and nodedev-dumpxml can benifit from the

	PCI devices, WWN makes no sense for them.

	nodedev: Implement virNodeDeviceLookupSCSIHostByWWN
	This just simply changes nodeDeviceLookupByWWN to be not static,
	and its name into nodeDeviceLookupSCSIHostByWWN. And use that for
	udev and HAL backends.

	remote: Wire up the remote protocol
	Like virNodeDeviceCreateXML, virNodeDeviceLookupSCSIHostByWWN
	has to be treated specially when generating the RPC codes. Also
	new rules are added in fixup_name to keep the name SCSIHostByWWN.

2013-02-12  Osier Yang  <jyang@redhat.com>

	Introduce API virNodeDeviceLookupSCSIHostByWWN
	Since the name (like scsi_host10) is not stable for vHBA, (it can
	be changed either after recreating or system rebooting), current
	API virNodeDeviceLookupByName is not nice to use for management app
	in this case. (E.g. one wants to destroy the vHBA whose name has
	been changed after system rebooting, he has to find out current
	name first).

	Later patches will support the persistent vHBA via storage pool,
	with which one can identify the vHBA stably by the wwnn && wwpn
	pair.

	Stop accessing driver->caps directly in QEMU driver
	The 'driver->caps' pointer can be changed on the fly. Accessing

	Rename 'qemuCapsXXX' to 'virQEMUCapsXXX'
	To avoid confusion between 'virCapsPtr' and 'qemuCapsPtr'
	do some renaming of various fucntions/variables. All

	Commit 39c77fe triggered random failures, depending on the platform
	and what other fds leak into the testsuite (for me, it passed on
	RHEL 6 but failed on Fedora 18).  The reason was that we were
	expecting an fd that fell outside of our reserved range.  By reserving
	a larger range, the test once again passes on all platforms.

	Introduce a virQEMUDriverConfigPtr object
	Currently the virQEMUDriverPtr struct contains an wide variety
	of data with varying access needs. Move all the static config
	data into a dedicated virQEMUDriverConfigPtr object. The only
	locking requirement is to hold the driver lock, while obtaining
	an instance of virQEMUDriverConfigPtr. Once a reference is held
	on the config object, it can be used completely lockless since
	it is immutable.

	NB, not all APIs correctly hold the driver lock while getting
	a reference to the config object in this patch. This is safe
	for now since the config is never updated on the fly. Later
	patches will address this fully.

	virFileWrapperFd: Switch to new virCommandDoAsyncIO
	Commit 34e8f63a32f83 introduced support for catching errors from
	libvirt iohelper. However, at those times there wasn't such fancy
	API as virCommandDoAsyncIO(), so everything has to be implemented
	on our own. But since we do have the API now, we can use it and
	drop our implementation then.

	tests: Create test for virCommandDoAsyncIO
	This is just a basic test, so we don't break virCommand in the
	future. A "Hello world\n" string is written to commanhelper,
	which copies input to stdout and stderr where we read it from.
	Then the read strings are compared with expected values.

	Introduce event loop to commandtest
	This is just preparing environment for the next patch, which is

	virCommand: Introduce virCommandDoAsyncIO
	Currently, if we want to feed stdin, or catch stdout or stderr of a
	virCommand we have to use virCommandRun(). When using virCommandRunAsync()
	we have to register FD handles by hand. This may lead to code duplication.
	Hence, introduce an internal API, which does this automatically within
	virCommandRunAsync(). The intended usage looks like this:

	    virCommandPtr cmd = virCommandNew*(...);
	    char *buf = NULL;

	    ...

	    virCommandSetOutputBuffer(cmd, &buf);
	    virCommandDoAsyncIO(cmd);

	    if (virCommandRunAsync(cmd, NULL) < 0)
	        goto cleanup;

	    ...

	    if (virCommandWait(cmd, NULL) < 0)
	        goto cleanup;

	    /* @buf now contains @cmd's stdout */
	    VIR_DEBUG("STDOUT: %s", NULLSTR(buf));

	    ...

	cleanup:
	    VIR_FREE(buf);
	    virCommandFree(cmd);

	Note, that both stdout and stderr buffers may change until virCommandWait()
	returns.

2013-02-02  Matthias Bolte  <matthias.bolte@googlemail.com>

	esx: Simplify esxPrivate pointer handling in esxOpen
	Commit 4445e16bfa8056980ac643fabf17186f9e685925 changed the signature
	of esxConnectToHost and esxConnectToVCenter by replacing the esxPrivate
	pointer with virConnectPtr. The esxPrivate pointer was then retrieved
	again from virConnectPtr's privateData. This resulted in a NULL pointer
	dereference, because the privateData pointer was not yet initialized at
	the point where esxConnectToHost and esxConnectToVCenter are called.

	This was fixed in commit b126715a48cd0cbe32ec6468c267cd8cf2961c55 that
	moved the initialization of privateData before the problematic calls.

	Simplify the logic by making the call to esxFreePrivate unconditional and
	changing esxConnectToHost and esxConnectToVCenter back to take a esxPrivate
	pointer directly. This allows to assign esxPrivate to the virConnectPtr's
	privateData pointer as one of the last steps in esxOpen making it more
	obvious that it is not initialized during the earlier steps of esxOpen.

	conf: Don't format cputune element when not needed
	Commit 60b176c3d0f0d5037acfa5e27c7753f657833a0b introduced a bug that
	when editing an XML with cputune similar to this:

	...
	  <vcpu placement='static' current='1'>2</vcpu>
	  <cputune>
	    <vcpupin vcpu="1" cpuset="0"/>
	  </cputune>
	...

	results in formatted XML that looks like this:

	...
	  <vcpu placement='static' current='1'>2</vcpu>
	  <cputune>
	  </cputune>
	...

	That is caused by a condition depending on def->cputune.vcpupin being
	set rather than checking def->cputune.nvcpupin.  Notice that nvcpupin
	can be 0 and vcpupin can still be allocated since it's a pointer to an
	array, so no harm done there.

	I also changed it on other places in the code where it depended on the
	wrong variable.

	rpc: Fix crash on error paths of message dispatching
	This patch resolves CVE-2013-0170:
	https://bugzilla.redhat.com/show_bug.cgi?id=893450

	When reading and dispatching of a message failed the message was freed
	but wasn't removed from the message queue.

	After that when the connection was about to be closed the pointer for
	the message was still present in the queue and it was passed to
	virNetMessageFree which tried to call the callback function from an
	uninitialized pointer.

	This patch removes the message from the queue before it's freed.

	qemu_hotplug: Rework media changing process
	https://bugzilla.redhat.com/show_bug.cgi?id=892289

	It seems like with new udev within guest OS, the tray is locked,
	so we need to:
	- 'eject'
	- wait for tray to open
	- 'change'

	Moreover, even when doing bare 'eject', we should check for
	'tray_open' as guest may have locked the tray. However, the
	waiting phase shouldn't be unbounded, so I've chosen 10 retries
	maximum, each per 500ms. This should give enough time for guest
	to eject a media and open the tray.

	libxl: Domain event handler improvements
	Since libxl provides the domain ID in the event handler callback,
	find the domain object based on the ID.  This approach prevents
	processing the callback on a domain that has already been reaped.

	Also, similar to the xl implementation, ignore the SUSPEND shutdown
	reason.  By calling libxl_domain_suspend(), we know a shutdown
	event with SUSPEND reason will be generated, but it can be safely
	ignored since any subsequent cleanup will be done by the callers.

	libxl: Fix race between destruction of objects
	It is possible to destroy and cleanup a VM, resulting in freeing the

	Fix this race by incrementing the reference count on libxlDomainObjPrivate
	for each fd and timeout registration.  Only when all fds and timeouts are
	deregistered and destroyed will the libxlDomainObjPrivate be destroyed.

	libxl: Fix races in libxl event code
	The libxl driver is racy in it's interactions with libxl and libvirt's

	the event.

	This patch fixes the race by converting libxlDomainObjPrivate to a
	virObjectLockable, and locking it while executing libxl upcalls and
	libvirt event loop callbacks.

	Note that using the virDomainObj lock is not satisfactory since it may
	be desirable to hold the virDomainObj lock even when libxl events such
	as reading and writing to xenstore need processed.

	to a value _different_ than what they were already given as enums

	    qemu: Fix QMP Capabability Probing Failure

	which attempted to make sure the QEMU process used for probing
	ran as the right user id, caused serious performance regression
	and unreliability in probing. The -daemonize switch in QEMU
	guarantees that the monitor socket is present before the parent
	process exits. This means libvirtd is guaranteed to be able to
	connect immediately. By switching from -daemonize to the
	virCommandDaemonize API libvirtd was no longer synchronized with
	QEMU's startup process. The result was that the QEMU monitor
	failed to open and went into its 200ms sleep loop. This happened
	for all 25 binaries resulting in 5 seconds worth of sleeping
	at libvirtd startup. In addition sometimes when libvirt connected,
	QEMU would be partially initialized and crash causing total
	failure to probe that binary.

	This commit reverts the previous change, ensuring we do use the
	-daemonize flag to QEMU. Startup delay is cut from 7 seconds
	to 2 seconds on my machine, which is on a par with what it was
	prior to the capabilities rewrite.

	To deal with the fact that QEMU needs to be able to create the
	pidfile, we switch pidfile location fron runDir to libDir, which
	QEMU is guaranteed to be able to write to.

	qemu: escape ipv6 for rbd network disk hosts

	The closeDef->cb function may well cause the current callback

	The core_id is guaranteed to be unique within a cell and a socket. There
	may be duplicates between sockets. Only cores sharing core_id within one

	S390: Enhance memballoon handling for virtio-s390
	The way in that memory balloon suppression was handled for S390
	is flawed for a number or reasons.
	1. Just preventing the default balloon to be created in the case
	   of VIR_ARCH_S390[X] is not sufficient. An explicit memballoon
	   element in the guest definition will still be honored, resulting
	   both in a -balloon option and the allocation of a PCI bus address,
	   neither being supported.
	2. Prohibiting balloon for S390 altogether at a domain_conf level
	   is no good solution either as there's work in progress on the QEMU
	   side to implement a virtio-balloon device, although in
	   conjunction with a new machine type. Suppressing the balloon
	   should therefore be done at the QEMU driver level depending
	   on the present capabilities.

	Therefore we remove the conditional suppression of the default
	balloon in domain_conf.c.
	Further, we are claiming the memballoon device for virtio-s390
	during device address assignment to prevent it from being considered
	as a PCI device.
	Finally, we suppress the generation of the balloon command line option
	if this is a virtio-s390 machine.

	qemu_agent: Ignore expected EOFs
	https://bugzilla.redhat.com/show_bug.cgi?id=892079

	One of my previous patches (f2a4e5f176c408) tried to fix crashing
	libvirtd on domain detroy. However, we need to copy pattern from
	qemuProcessHandleMonitorEOF() instead of decrementing reference
	counter. The rationale for this is, if qemu process is dying due
	to domain being destroyed, we obtain EOF on both the monitor and
	agent sockets. However, if the exit is expected, qemuProcessStop
	is called, which cleans both agent and monitor sockets up. We
	want qemuAgentClose() to be called iff the EOF is not expected,
	so we don't leak an FD and memory. Moreover, there could be race
	with qemuProcessHandleMonitorEOF() which could have already
	closed the agent socket, in which case we don't want to do
	anything.

	qemu: Support ram bar size for qxl devices
	Adds a "ram" attribute globally to the video.model element, that changes
	the resulting qemu command line only if video.type == "qxl".

	<video>
	  <model type='qxl' ram='65536' vram='65536' heads='1'/>
	</video>

	That attribute gets a default value of 64*1024. The schema is unchanged
	for other video element types.

	The resulting qemu command line change is the addition of

	-global qxl-vga.ram_size=<ram>*1024

	or

	-global qxl.ram_size=<ram>*1024

	For the main and secondary qxl devices respectively.

	The default for the qxl ram bar is 64*1024 kilobytes (the same as the
	default qxl vram bar size).

	|    %ifnarch %{ix86} x86_64 ia64

	|// # RHEL-5 builds are client-only for s390, ppc
	|#if a // 0%{?rhel} == 5
	|# if a // %{ix86} x86_64 ia64

	With each extra VM I start, the messages get amplified

	conf: don't fail to parse <boot> when parsing a single device
	This resolves:

	  https://bugzilla.redhat.com/show_bug.cgi?id=895294

	The symptom was that attempts to modify a network device using
	virDomainUpdateDeviceFlags() would fail if the original device had a
	<boot> element (e.g. "<boot order='1'/>"), even if the updated device
	had the same <boot> element. Instead, the following error would be logged:

	  cannot modify network device boot index setting

	It's true that it's not possible to change boot order (internally
	known as bootIndex) of a live device; qemuDomainChangeNet checks for
	that, but the problem was that the information it was checking was
	incorrect.

	Explanation:

	When a complete domain is parsed, a global (to the domain) "bootMap"
	is passed down to the parse for each device; the bootMap is used to
	make sure that devices don't have conflicting settings for their boot
	orders.

	When a single device is parsed by itself (as in the case of
	virDomainUpdateDeviceFlags), there is no global bootMap that would be
	appropriate to send, so NULL is sent instead. However, although the
	lowest level function that parses just the boot order *does* simply
	skip the sanity check in that case, the next higher level
	"virDomainDeviceInfoParseXML" function refuses to call down to the
	lower "virDomainDeviceBootParseXML" if bootMap is NULL. So, the boot
	order is never set in the "new" device object, and when it is compared
	to the original (which does have a boot order), they don't match.

	The fix is to patch virDomainDeviceInfoParseXML to not care about
	bootMap, and just always call virDomainDeviceInfoBootParseXML whenever
	there is a <boot> element. When we are only parsing a single device,
	we don't care whether or not any specified boot order is consistent
	with the rest of the domain; we will always do this check later (in
	the current case, we do it by verifying that the net bootIndex exactly
	matches the old bootIndex).

	network: use bandwidth from portgroup when appropriate
	The bandwidth plug and unplug functions were assuming that an
	interface's bandwidth setting was always specified directly in the
	domain's <interface> definition, but that's not necessarily true - it
	could have been obtained from a <portgroup> definition in the network
	definition. This patch fixes those functions to use
	virDomainNetGetActualBandwidth(), which gets the bandwidth pointer
	from iface->data.network.actual if it exists, otherwise returns
	iface->bandwidth.

	network: Resolve some issues around vlan copying
	Remove extraneous check for 'netdef' when dereferencing for vlan.nTags.
	Prior code would already check if netdef was NULL.

	Coverity complained about a path where the 'vlan' was potentially valid,
	but a prior checks may not have allocated 'iface->data.network.actual',
	so like other paths it needs to be allocated on the fly.

	Move the copying of vlan up earlier in networkAllocateActualDevice, so
	that actual.type gets properly set.

	Since the first assignment to vlan is redundant except in the case of
	jumping immediately to validate from the start of the function,
	eliminate its initial setting at the top of the function in favor of
	calling the helper function virDomainNetGetActualVlan() (which doesn't
	depend on the local vlan pointer being initialized) down at validate:

	libvirt.c: fix typo in comment

2013-01-17  Claudio Bley  <cbley@av-test.de>

	Move comments after enum members
	The api builder always associates comments to the last member it read,
	not to the current member even if there was a comment for the previous
	member and a comma was already seen.

	This has the effect that the comment for the previous member gets
	overwritten and the current member has no comment at all.

	Introduce an LXC specific public API & library
	This patch introduces support for LXC specific public APIs. In
	common with what was done for QEMU, this creates a libvirt_lxc.so
	library and libvirt/libvirt-lxc.h header file.

	The actual APIs are

	  int virDomainLxcOpenNamespace(virDomainPtr domain,
	                                int **fdlist,
	                                unsigned int flags);

	  int virDomainLxcEnterNamespace(virDomainPtr domain,
	                                 unsigned int nfdlist,
	                                 int *fdlist,
	                                 unsigned int *noldfdlist,
	                                 int **oldfdlist,
	                                 unsigned int flags);

	which provide a way to use the setns() system call to move the
	calling process into the container's namespace. It is not
	practical to write in a generically applicable manner. The
	nearest that we could get to such an API would be an API which
	allows to pass a command + argv to be executed inside a
	container. Even if we had such a generic API, this LXC specific
	API is still useful, because it allows the caller to maintain
	the current process context, in particular any I/O streams they
	have open.

	NB the virDomainLxcEnterNamespace() API is special in that it
	runs client side, so does not involve the internal driver API.

	Add a test suite for validating SELinux labelling
	There are many aspects of the guest XML which result in the
	SELinux driver applying file labelling. With the increasing
	configuration options it is desirable to test this behaviour.
	It is not possible to assume that the test suite has the
	ability to set SELinux labels. Most filesystems though will
	support extended attributes. Thus for the purpose of testing,
	it is possible to extend the existing LD_PRELOAD hack to
	override setfilecon() and getfilecon() to simply use the
	'user.libvirt.selinux' attribute for the sake of testing.

2013-01-11  Daniel P. Berrange  <berrange@redhat.com>

	Add some autoconf helper macros for checking for libraries
	Most checks for libraries take the same format

	  * --with-libFOO=yes|no|check|/some/path  argument
	  * check for a function NNN in libFOO.so
	  * check for a header file DDD/HHH.h
	  * Define a WITH_FOO config.h symbol
	  * Define a WITH_FOO make conditional
	  * Substitute FOO_CFLAGS and FOO_LIBS make variables
	  * Print CFLAGS & LIBS summary at the end

	Doing all this correctly is rather difficult, typically
	done by copy+paste of a previous usage. Further small
	improvements people make are not applied to all previous
	usages.

	Improve this by creating some helper macros to apply
	good practice. First, to perform the actual checks:

	  LIBVIRT_CHECK_LIB([SELINUX], [selinux],
	     [getfilecon], [selinux/selinux.h])

	This checks for 'getfilecon' in -lselinux, and the
	existence of 'selinux/selinux.h' header file. If successful
	it sets SELINUX_CFLAGS and SELINUX_LIBS. The WITH_SELINUX
	config.h macro and WITH_SELINUX make conditional are also
	defined.

	In some cases we need to check two variants of the same
	library

	  LIBVIRT_CHECK_LIB_ALT([SASL], [sasl2],
	                        [sasl_client_init], [sasl/sasl.h],
	                        [SASL1], [sasl],
	                        [sasl_client_init], [sasl/sasl.h])

	This checks for sasl_client_init in libsasl2, and if that
	is not found, checks sasl_client_init in libsasl. If the
	first check succeeds WITH_SASL is set, while if the second
	check succeeds *both* WITH_SASL and WITH_SASL1 are set.

	If the library supports pkg-config, then another variant
	is available

	phyp: Resolve some file descriptor leaks
	The phypUUIDTable_Push and phypUUIDTable_Pull leaked their file descriptors
	on normal return.  Each function had an unnecessary use of creating a buffer
	to print conn->uri->user and needed a bit better flow control. I also noted
	that the Read function had a cut-n-paste error from the write function on a
	couple of VIR_WARN's.

	The openSSHSession leaked the sock on the failure path.  Additionally that
	turns into the internal_socket in the phypOpen code.  That was neither saved
	nor closed on any path. So I used the connnection_data->sock field to save
	the socket for eventual close. Of interest here is that phypExec used the
	connection_data->sock field even though it had never been initialized.

	maint: don't distribute generated .def files
	I ran 'make dist' in the directory left over from ./autobuild.sh
	(which was configured for a mingw cross build); the resulting
	tarball had more files than 'make dist' on a normal Linux build.
	I traced it to the fact that we were distributing a generated
	file, but only when configure said the end user had to generate
	the file in the first place.  In the process, I noticed that
	we had some difference in symbol file names; I added a comment
	explaining why the difference exists (after first trying to

	qemu_agent: Remove agent reference only when disposing it
	https://bugzilla.redhat.com/show_bug.cgi?id=892079

	With current code, if user calls virDomainPMSuspendForDuration()
	followed by virDomainDestroy(), the former API checks for qemu agent
	presence, which will evaluate as true (if agent is configured). While
	talking to qemu agent, the qemu driver is unlocked, so the latter API
	starts executing.  However, if machine dies meanwhile, libvirtd gets
	EOF on the agent socket and qemuProcessHandleAgentEOF() is called. The
	handler clears reference to qemu agent while the destroy API already
	holding a reference to it. This leads to NULL dereferencing later in
	the code. Therefore, the agent pointer should be set to NULL only if
	we are the exclusive owner of it.

	POSIX does not guarantee whether uid_t and gid_t are signed or

	size, or larger than int (or even the same size as one another).
	Therefore, it is possible to have platforms where '(uid_t)-1==-1'

	thanks to integer promotion rules.  The only portable way to use
	the placeholder value of these two types is to always use a cast.
	Thankfully, the issue is mostly theoretical - sanlock only
	compiles on Linux for now, and on Linux, these types do not

	qemu: Relax hard RSS limit
	Currently, if there's no hard memory limit defined for a domain,
	libvirt tries to calculate one, based on domain definition and magic
	equation and set it upon the domain startup. The rationale behind was,
	if there's a memory leak or exploit in qemu, we should prevent the
	host system trashing. However, the equation was too tightening, as it
	didn't reflect what the kernel counts into the memory used by a
	process. Since many hosts do have a swap, nobody hasn't noticed
	anything, because if hard memory limit is reached, process can
	continue allocating memory on a swap. However, if there is no swap on
	the host, the process gets killed by OOM killer. In our case, the qemu
	process it is.

	To prevent this, we need to relax the hard RSS limit. Moreover, we
	should reflect more precisely the kernel way of accounting the memory
	for process. That is, even the kernel caches are counted within the
	memory used by a process (within cgroups at least). Hence the magic
	equation has to be changed:

	  limit = 1.5 * (domain memory + total video memory) + (32MB for cache
	          per each disk) + 200MB

	Fix virLXCPrepareHostDevices method
	The virLXCPrepareHostDevices method was returning success even
	when it reported an error, and failed to handle several host
	device types

	Ensure we always setup a private mount namespace for LXC controller
	The code for setting up a private /dev/pts for the containers
	is also responsible for making the LXC controller have a
	private mount namespace. Unfortunately the /dev/pts code is
	not run if launching a container without a custom root. This
	causes the LXC FUSE mount to leak into the host FS.

	Speed up fallback to legacy non-QMP probing
	Since we daemonized QEMU for capabilities probing there is a long
	time if QEMU fails to launch. This is because we're not passing in
	any virDomainObjPtr instance and thus the monitor code can not
	check to see if the PID is still alive.

	Only initialize capabilities after setting dir permissions
	The current code is initializing capabilities before setting
	directory permissions. Thus the QEMU binaries being run may
	not have the ability to create the UNIX monitor socket on
	the first run of libvirtd.

2013-01-05  Peter Krempa  <pkrempa@redhat.com>

	snapshot: qemu: Fix segfault and vanishing snapshots when redefining
	When the disk alignment check done while redefining an existing snapshot
	failed, the qemu driver attempted to free the existing snapshot. As in
	the cleanup path the definition of the snapshot wasn't assigned, the
	cleanup code dereferenced a NULL pointer.

	This patch changes the behavior on error paths while redefining snapshot
	in two ways:

	1) On failure, modifications done on the snapshot definition object are
	rolled back.

	util: fix botched check for new netlink request filters
	This is an adjustment to the fix for

	  https://bugzilla.redhat.com/show_bug.cgi?id=889319

	to account for two bonehead mistakes I made.

	commit ac2797cf2af2fd0e64c58a48409a8175d24d6f86 attempted to fix a
	problem with netlink in newer kernels requiring an extra attribute
	with a filter flag set in order to receive an IFLA_VFINFO_LIST from
	netlink. Unfortunately, the #ifdef that protected against compiling it
	in on systems without the new flag went a bit too far, assuring that
	the new code would *never* be compiled, and even if it had, the code
	was incorrect.

	The first problem was that, while some IFLA_* enum values are also
	their existence at compile time, IFLA_EXT_MASK *isn't* #defined, so
	checking to see if it's #defined is not a valid method of determining
	whether or not to add the attribute. Fortunately, the flag that is
	being set (RTEXT_FILTER_VF) *is* #defined, and it is never present if
	IFLA_EXT_MASK isn't, so it's sufficient to just check for that flag.

	And to top it off, due to the code not actually compiling when I
	thought it did, I didn't realize that I'd been given the wrong arglist
	to nla_put() - you can't just send a const value to nla_put, you have
	to send it a pointer to memory containing what you want to add to the
	message, along with the length of that memory.

	This time I've actually sent the patch over to the other machine
	that's experiencing the problem, applied it to the branch being used
	(0.10.2) and verified that it works properly, i.e. it does fix the
	problem it's supposed to fix. :-/

	The code for doing a block-copy was supposed to track the destination

	However, the wrong variable was being written; later in the code we
	silently did 'disk->mirror = mirror' which was still NULL, and thus
	leaking memory and leaving libvirt to think that the mirror job was
	never started, which prevented a pivot operation after a copy.
	Problem introduced in commit 35c7701c6.

	util: fix functions that retrieve SRIOV VF info
	This patch resolves:

	  https://bugzilla.redhat.com/show_bug.cgi?id=889319

	When assigning an SRIOV virtual function to a guest using "intelligent
	PCI passthrough" (<interface type='hostdev'>, which sets the MAC
	address and vlan tag of the VF before passing its info to qemu),
	libvirt first learns the current MAC address and vlan tag by sending
	an NLM_F_REQUEST message for the VF's PF (physical function) to the
	kernel via a NETLINK_ROUTE socket (see virNetDevLinkDump()); the
	response message's IFLA_VFINFO_LIST section is examined to extract the
	info for the particular VF being assigned.

	This worked fine with kernels up until kernel commit
	115c9b81928360d769a76c632bae62d15206a94a (first appearing in upstream
	kernel 3.3) which changed the ABI to not return IFLA_VFINFO_LIST in
	the response until a newly introduced IFLA_EXT_MASK field was included
	in the request, with the (newly introduced, of course) RTEXT_FILTER_VF
	flag set.

	The justification for this ABI change was that new fields had been
	added to the VFINFO, causing NLM_F_REQUEST messages to fail on systems
	with large numbers of VFs if the requesting application didn't have a
	large enough buffer for all the info. The idea is that most
	applications doing an NLM_F_REQUEST don't care about VFINFO anyway, so
	eliminating it from the response would lower the requirements on
	buffer size. Apparently, the people who pushed this patch made the
	mistaken assumption that iproute2 (the "ip" command) was the only
	package that used IFLA_VFINFO_LIST, so it wouldn't break anything else
	(and they made sure that iproute2 was fixed.

	The logic of this "fix" is debatable at best (one could claim that the
	proper fix would be for the applications in question to be fixed so
	that they properly sized the buffer, which is what libvirt does
	(purely by virtue of using libnl), but it is what it is and we have to
	deal with it.

	In order for <interface type='hostdev'> to work properly on systems
	with a kernel 3.3 or later, libvirt needs to add the afore-mentioned
	IFLA_EXT_MASK field with RTEXT_FILTER_VF set.

	Of course we also need to continue working on systems with older
	kernels, so that one bit of code is compiled conditionally. The one
	time this could cause problems is if the libvirt binary was built on a
	system without IFLA_EXT_MASK which was subsequently updated to a
	kernel that *did* have it. That could be solved by manually providing
	the values of IFLA_EXT_MASK and RTEXT_FILTER_VF and adding it to the
	message anyway, but I'm uncertain what that might actually do on a
	system that didn't support the message, so for the time being we'll
	just fail in that case (which will very likely never happen anyway).

2012-12-21  Laine Stump  <laine@laine.org>

	util: add missing error log messages when failing to get netlink VFINFO
	This patch fixes the lack of error messages when libvirt fails to find
	VFINFO in a returned netlinke response message.

	https://bugzilla.redhat.com/show_bug.cgi?id=827519#c10 is an example
	of the error message that was previously logged when the
	IFLA_VFINFO_LIST object was missing from the netlink response. The
	reason for this failure is detailed in

	   https://bugzilla.redhat.com/show_bug.cgi?id=889319

	Even though that root problem has been fixed, the experience of
	finding the root cause shows us how important it is to properly log an
	error message in these cases. This patch *seems* to replace the entire
	function, but really most of the changes are due to moving code that
	was previously inside an if() statement out to the top level of the
	function (the original if() was reversed and made to log an error and
	return).

	network: don't require private addresses if dnsmasq uses SO_BINDTODEVICE
	This is yet another refinement to the fix for CVE-2012-3411:

	   https://bugzilla.redhat.com/show_bug.cgi?id=833033

	It turns out that it would be very intrusive to correctly backport the
	entire --bind-dynamic option to older dnsmasq versions
	(e.g. dnsmasq-2.48 that is used on RHEL6.x and CentOS 6.x), but very
	simple to patch those versions to just use SO_BINDTODEVICE on all
	their listening sockets (SO_BINDTODEVICE also has the desired effect
	of permitting only traffic that was received on the interface(s) where
	dnsmasq was set to listen.)

	This patch modifies the dnsmasq capabilities detection to detect the
	string:

	    --bind-interfaces with SO_BINDTODEVICE

	in the output of "dnsmasq --version", and in that case realize that
	using the old --bind-interfaces option is just as safe as
	--bind-dynamic (and therefore *not* forbid creation of networks that
	use public IP address ranges).

	If -bind-dynamic is available, it is still preferred over
	--bind-interfaces.

	Note that this patch does no harm in upstream, or in any distro's
	downstream if it happens to end up there, but builds for distros that
	have a new enough dnsmasq to support --bind-dynamic do *NOT* need to
	specifically backport this patch; it's only required for distro
	releases that have dnsmasq too old to have --bind-dynamic (and those
	distros will need to add the SO_BINDTODEVICE patch to dnsmasq,
	*including the extra string in the --version output*, as well.

	Wire up the attach/detach/update device APIs to support changing

	Add basic driver API framework for device attach/detach support in LXC
	This wires up the LXC driver to support the domain device attach/
	detach/update APIs, following the same code design as used in
	the QEMU driver. No actual changes are possible with this commit,
	it is only providing the framework

	Add support for misc host device passthrough with LXC
	This extends support for host device passthrough with LXC to
	cover misc devices. In this case all we need todo is a
	mknod in the container's /dev and whitelist the device in
	cgroups

	Add support for storage host device passthrough with LXC
	This extends support for host device passthrough with LXC to
	cover storage devices. In this case all we need todo is a
	mknod in the container's /dev and whitelist the device in
	cgroups

	Add support for USB host device passthrough with LXC
	This adds support for host device passthrough with the
	LXC driver. Since there is only a single kernel image,
	it doesn't make sense to pass through PCI devices, but
	USB devices are fine. For the latter we merely need to
	make the /dev/bus/usb/NNN/MMM character device exist
	in the container's /dev

	Add support for disks with LXC
	Currently LXC guests can be given arbitrary pre-mounted
	filesystems, however, for some usecases it is more appropriate
	to provide block devices which the container can mount itself.
	This first impl only allows for <disk type='block'>, in other
	words exposing a host disk device to a container. Since LXC
	does not have device namespace virtualization, we are cheating
	a little bit. If the XML specifies /dev/sdc4 to be given to
	the container as /dev/sda1, when we do the mknod /dev/sda1
	in the container's /dev, we actually use the major:minor
	number of /dev/sdc4, not /dev/sda1.

	Add support for SELinux labelling of hostdev storage/misc devices
	The SELinux security driver needs to learn to label storage/misc
	hostdev devices for LXC

	Refactor SELinux security driver hostdev labelling
	Prepare to support different types of hostdevs by refactoring
	the current SELinux security driver code

	Allow passing a vroot into security manager hostdev labelling
	When LXC labels USB devices during hotplug, it is running in
	host context, so it needs to pass in a vroot path to the
	container root.

	Skip bulk relabelling of resources in SELinux driver when used with LXC
	The virSecurityManager{Set,Restore}AllLabel methods are invoked
	at domain startup/shutdown to relabel resources associated with
	a domain. This works fine with QEMU, but with LXC they are in
	fact both currently no-ops since LXC does not support disks,
	hostdevs, or kernel/initrd files. Worse, when LXC gains support
	for disks/hostdevs, they will do the wrong thing, since they
	run in host context, not container context. Thus this patch
	turns then into a formal no-op when used with LXC. The LXC
	controller will call out to specific security manager labelling
	APIs as required during startup.

	Refactor LXC NIC creation to allow reuse by hotplug code
	The code for creating veth/macvlan devices is part of the
	LXC process startup code. Refactor this a little and export
	the methods to the rest of the LXC driver. This allows them
	to be reused for NIC hotplug code

2012-12-18  Daniel P. Berrange  <berrange@redhat.com>

	Add support for <hostdev mode="capabilities">
	The <hostdev> device type has long had a redundant "mode"
	attribute, which has always been "subsys". This finally
	introduces a new mode "capabilities", which will be used
	by the LXC driver for device assignment. Since container
	based virtualization uses a single kernel, the idea of
	assigning physical PCI devices doesn't make sense. It is
	still reasonable to assign USB devices, but for assigning
	arbitrary nodes in /dev, the new 'capabilities' mode is
	to be used.

	The first capability support is 'storage', which is for
	assignment of block devices. Functionally this is really
	pretty similar to the <disk> support. The only difference
	is the device node name is identical in both host and
	container namespaces.

	    <hostdev mode='capabilities' type='storage'>
	      <source>
	        <block>/dev/sdf1</block>
	      </source>
	    </hostdev>

	The second capability support is 'misc', which is for
	assignment of character devices. There is no existing
	parallel to this. Again the device node is the same
	inside & outside the container.

	    <hostdev mode='capabilities' type='misc'>
	      <source>
	        <char>/dev/input/event3</char>
	      </source>
	    </hostdev>

	The reason for keeping the char & storage devices
	separate in the domain XML, is to mirror the split
	in the node device XML. NB the node device XML does
	not yet report character devices, but that's another
	new patch to come

	S390: Fix virSysinfoRead memory corruption
	There was a double free issue caused by virSysinfoRead on s390,
	as the same manufacturer string instance was assigned to more
	than one processor record.
	Cleaned up other potential memory issues and restructured the sysinfo
	parsing code by moving repeating patterns into a helper function.

	The restructuring made it necessary to conditionally disable
	-Wlogical-op for some older GCC versions, using pragma GCC diagnostic.
	This is a GCC specific pragma, which is acceptable, since we're
	using it to work around a GCC specific bug.

	Finally, added a function virSysinfoSetup to configure the sysinfo
	data source files/script during run time, to facilitate writing test
	programs. This function is not published in sysinfo.h and only
	there for testing.

	<domain>

	    <model fallback='allow' vendor_id='aaaabbbbcccc'>core2duo</model>

	Support custom 'svirt_tcg_t' context for TCG based guests
	The current SELinux policy only works for KVM guests, since
	TCG requires the 'execmem' privilege. There is a 'virt_use_execmem'
	boolean to turn this on globally, but that is unpleasant for users.
	This changes libvirt to automatically use a new 'svirt_tcg_t'
	context for TCG based guests. This obsoletes the previous
	boolean tunable and makes things 'just work(tm)'

	Since we can't assume we run with new enough policy, I also
	make us log a warning message (once only) if we find the policy
	lacks support. In this case we fallback to the normal label and
	expect users to set the boolean tunable

	             (there is also '-device qxl' for secondary devices)
	'-device vmware-svga' maps to '-vga vmware'

	For qemu(>=1.2), we can use -device to replace -vga for video
	device. For the primary video device, the patch tries to use 0x2
	slot for matching old qemu. If the 0x2 slot is allocated already,
	the addr property could help for using any available slot.
	For qemu(< 1.2), we keep using -vga for primary device.

	The reason of this changing is that for qemu, only one primary video

	qemu: don't fail update netdev on bridge detach failure
	When a network device's bridge connection is changed by
	virDomainUpdateDevice, libvirt first removes the netdev's tap from its
	old bridge, then adds it to the new bridge. Sometimes, due to a
	network being destroyed while a guest device is still attached, the
	tap may already be "removed" from the old bridge (or the old bridge
	may not even exist any more); the existing code was needlessly failing
	the update when this happened, making it impossible to recover from
	the situation without completely detaching (i.e. removing) the netdev
	from the guest and re-attaching.

	Instead of failing the entire operation when removal of the tap from
	the old bridge fails, this patch changes qemuDomainChangeNetBridge to
	just log a warning and continue, allowing a reasonable recover from
	the situation.

	(you'll appreciate this change if you ever accidentally destroy a
	network while your guests are still using it).

	network: prevent dnsmasq from listening on localhost
	This patch resolves the problem reported in:

	   https://bugzilla.redhat.com/show_bug.cgi?id=886663

	The source of the problem was the fix for CVE 2011-3411:

	   https://bugzilla.redhat.com/show_bug.cgi?id=833033

	which was originally committed upstream in commit
	753ff83a50263d6975f88d6605d4b5ddfcc97560. That commit improperly
	removed the "--except-interface lo" from dnsmasq commandlines when
	--bind-dynamic was used (based on comments in the latter bug).

	It turns out that the problem reported in the CVE could be eliminated
	without removing "--except-interface lo", and removing it actually
	caused each instance of dnsmasq to listen on localhost on port 53,
	which created a new problem:

	If another instance of dnsmasq using "bind-interfaces" (instead of
	"bind-dynamic") had already been started (or if another instance
	started later used "bind-dynamic"), this wouldn't have any immediately
	visible ill effects, but if you tried to start another dnsmasq
	instance using "bind-interfaces" *after* starting any libvirt
	networks, the new dnsmasq would fail to start, because there was
	already another process listening on port 53.

	(Subsequent to the CVE fix, another patch changed the network driver
	to put dnsmasq options in a conf file rather than directly on the
	dnsmasq commandline, but preserved the same options.)

	This patch changes the network driver to *always* add
	"except-interface=lo" to dnsmasq conf files, regardless of whether we use
	bind-dynamic or bind-interfaces. This way no libvirt dnsmasq instances
	are listening on localhost (and the CVE is still fixed).

	The actual code change is miniscule, but must be propogated through all
	of the test files as well.

	Since we (ab)use vshReconnect for the default URI connection, if it
	fails it might print 'Failed to reconnect to the hypervisor' even if we
	were never connected before.

	This changes it to only mention reconnection on the first try after
	getting disconnected.

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Add support for locking based on SCSI volume ID

	Add support for locking based on LVM volume uuid

	Add ability to maintain disk leases indirectly
	The default lockd driver behavour is to acquire leases
	directly on the disk files. This introduces an alternative
	mode, where leases are acquire indirectly on a file that
	is based on a SHA256 hash of the disk filename.

	Add a virtlockd client as a lock driver impl
	This adds a 'lockd' lock driver which is just a client which
	talks to the lockd daemon to perform all locking. This will
	be the default lock driver for any hypervisor which needs one.

	* src/Makefile.am: Add lockd.so plugin
	* src/locking/lock_driver_lockd.c: Lockd driver impl

	Add support for re-exec() of virtlockd upon SIGUSR1
	The virtlockd daemon maintains file locks on behalf of libvirtd
	and any VMs it is running. These file locks must be held for as
	long as any VM is running. If virtlockd itself ever quits, then
	it is expected that a node would be fenced/rebooted. Thus to
	allow for software upgrads on live systemd, virtlockd needs the
	ability to re-exec() itself.

	Upon receipt of SIGUSR1, virtlockd will save its current live
	state out to a file /var/run/virtlockd-restart-exec.json
	It then re-exec()'s itself with exactly the same argv as it
	originally had, and loads the state file, reconstructing any
	objects as appropriate.

	The state file contains information about all locks held and
	all network services and clients currently active. An example
	state document is

	Enable systemd socket activation with virtlockd
	This enhancement virtlockd so that it can receive a pre-opened
	UNIX domain socket from systemd at launch time, and adds the
	systemd service/socket unit files

	* daemon/libvirtd.service.in: Require virtlockd to be running
	* libvirt.spec.in: Add virtlockd systemd files
	* src/Makefile.am: Install systemd files
	* src/locking/lock_daemon.c: Support socket activation
	* src/locking/virtlockd.service.in, src/locking/virtlockd.socket.in:
	  systemd unit files
	* src/rpc/virnetserverservice.c, src/rpc/virnetserverservice.h:
	  Add virNetServerServiceNewFD() method
	* src/rpc/virnetsocket.c, src/rpc/virnetsocket.h: Add virNetSocketNewListenFD
	  method

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Implement dispatch functions for lock protocol in virtlockd
	Introduce a lock_daemon_dispatch.c file which implements the
	server side dispatcher the RPC APIs previously defined in the
	lock protocol.

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Define a wire protocol for talking to the virtlockd daemon
	The virtlockd daemon will be responsible for managing locks
	on virtual machines. Communication will be via the standard
	RPC infrastructure. This provides the XDR protocol definition

	* src/locking/lock_protocol.x: Wire protocol for virtlockd
	* src/Makefile.am: Include lock_protocol.[ch] in virtlockd

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Introduce basic infrastructure for virtlockd daemon
	The virtlockd daemon will maintain locks on behalf of libvirtd.
	There are two reasons for it to be separate

	 - Avoid risk of other libvirtd threads accidentally
	   releasing fcntl() locks by opening + closing a file
	   that is locked
	 - Ensure locks can be preserved across libvirtd restarts.
	   virtlockd will need to be able to re-exec itself while
	   maintaining locks. This is simpler to achieve if its
	   sole job is maintaining locks

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Refactor creation of lock manager plugins
	Refactor virLockManagerPluginNew() so that the caller does
	not need to pass in the config file path itself - just the
	config directory and driver name.

	Fix QEMU to actually pass in a config file when creating the
	default lock manager plugin, rather than NULL.

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Fix error reporting when fetching SCSI/LVM keys
	The current  virStorageFileGet{LVM,SCSI}Key methods return
	the key as the return value. Unfortunately it is desirable
	for "NULL" to be a valid return value, as well as an error
	indicator. Thus the returned key must instead be provided
	as an out-parameter.

	When we invoke lvs or scsi_id to extract ID for block devices,
	we don't want virCommandWait logging errors messages. Thus we
	must explicitly check 'status != 0', rather than letting
	virCommandWait do it.

2012-12-13  Jim Fehlig  <jfehlig@suse.com>

	Support network boot for HVM guests in libxl
	The libxl driver ignored boot devices in the domain config,
	preventing PXE booting HVM domains.  This patch accounts for
	user-specified boot devices when building the libxl domain
	configuration.

2012-12-13  Daniel P. Berrange  <berrange@redhat.com>

	Fix probing of QED file format
	The QED file format is non-versioned, so although the magic
	value matched, libvirt rejected it due to lack of a version
	number to compare against. We need to distinguish this case
	by allowing a value of '-2' to indicate a non-versioned file
	where only the magic is required to match

	Add lots of debugging to storage file probing code

	Log warning if storage magic matches, but version does not
	To help us detect when new storage file versions come into
	existance log a warning if the storage file magic matches,
	but the version does not

	Fix memory leak in QEMU QMP capabilities initialization
	The qemuCapsInitQMP method never frees the QEMU 'package'
	version string.

	Change virCgroupGetAppRoot stub on non-Linux to avoid unused param warning
	Fully stub out the virCgroupGetAppRoot method as done with other
	methods in the file, rather than just the body. This lets us
	annotate the unused parameter to avoid a warning

2012-12-13  Eric Blake  <eblake@redhat.com>

	network: match xml warning message
	I noticed that /var/lib/libvirt/dnsmasq/*.conf used the wrong word;
	it was intended to match the wording in src/util/xml.c.

	* src/network/bridge_driver.c (networkDnsmasqConfContents): Fix typo.
	* tests/networkxml2confdata/*.conf: Update accordingly.

2012-12-13  Roman Bogorodskiy  <bogorodskiy@gmail.com>

	Qemu FreeBSD: fix compilation
	* Autotools changes:
	  - Don't assume Qemu is Linux-only
	  - Check Linux headers only on Linux
	  - Disable firewalld on FreeBSD
	* Initctl:
	  Initctl seem to present only on Linux, so stub it on other platforms
	* Raw I/O: Linux-only as well
	* Headers cleanup

	Drop mntent.h include.
	It's no longer used and also causes build fail on FreeBSD.

2012-12-13  Viktor Mihajlovski  <mihajlov@linux.vnet.ibm.com>

	Fix make check with different object directory
	make check fails in check-symsorting if configure is not run in
	the source directory. Prefixing symfile names with $(srcdir)
	fixes this.

	qemu: Improve error reporting from qemuDomainManagedSaveRemove
	Report an error if unlink of the managedsave file fails.

	qemu: Small code cleanups in the managedsave functions
	Save a few lines moving assignments into conditions and fix braces
	position.

	qemu: Refactor managed save functions to use domain lookup helpers

2012-12-12  Peter Krempa  <pkrempa@redhat.com>

	qemu: Add a new domain lookup helper and improve the docs
	This patch adds a new domain lookup helper qemuDomObjFromDomainDriver
	that lookups the domain and leaves the driver locked. The driver is
	returned as the second argument of that function. If the lookup fails
	the driver is unlocked to help avoid cleanup codepaths.

	This patch also improves docs for the helpers.

2012-12-12  Peter Krempa  <pkrempa@redhat.com>

	util: Fix warning message in previous patch
	I didn't notice the extra "does" in the previous patch. Remove it.

	util: rework error reporting in virGet(User|Group)IDByName
	This patch gets rid of the undeterministic error reporting code done on
	return values of get(pw|gr)nam_r. With this patch, if the group record
	is not returned by the corresponding function this error is not
	considered fatal even if errno != 0. The error is logged in such case.

2012-12-12  Daniel P. Berrange  <berrange@redhat.com>

	Refactor virDomainHostdevFind method
	Move the code for matching hostdev instances out of virDomainHostdevFind
	and into virDomainHostdevMatch method, which in turn calls out to other
	helper methods depending on the type of hostdev.

2012-12-12  Daniel P. Berrange  <berrange@redhat.com>

	Slightly refactor hostdev parsing / formating
	Rename virDomainHostdevPartsParse to virDomainHostdevDefParseSubsys
	to reflect the fact that it only deals with hostdevs uing the
	traditional mode=subsystem, and not mode=capabilities

	Rename virDomainHostSourceFormat to virDomainHostdevDefFormatSubsys
	for the same reason.

2012-12-12  Daniel P. Berrange  <berrange@redhat.com>

	Remove bogus const return values in storage file APIs
	virStorageFileGetLVMKey and virStorageFileGetSCSIKey
	both return heap allocated strings, so the return value
	should not be marked const.

	Add missing export of virStorageFileGetLVMKey & virStorageFileGetSCSIKey

	Fix sorting of libvirt_private.syms and add syntax check rule
	Add check-symsorting.pl to perform case-insensitive alphabetical
	sorting of groups of symbols. Fix all violations it reports

	uml: Report error if inotify fails on driver startup

2012-12-12  Cole Robinson  <crobinso@redhat.com>

	tools: Only install guests init script if --with-init=script=redhat
	Most of this deals with moving the libvirt-guests.sh script which
	does all the work to /usr/libexec, so it can be shared by both
	systemd and traditional init. Previously systemd depended on
	the script being in /etc/init.d

	Required to fix https://bugzilla.redhat.com/show_bug.cgi?id=789747

2012-12-12  Serge Hallyn  <serge.hallyn@ubuntu.com>

	add vnc unix sockets to apparmor policy
	When using vnc gaphics over a unix socket, virt-aa-helper needs to provide
	access for the qemu domain to access the sockfile.

	add security hook for permitting hugetlbfs access
	When a qemu domain is backed by huge pages, apparmor needs to grant the domain
	rw access to files under the hugetlbfs mount point.  Add a hook, called in
	qemu_process.c, which ends up adding the read-write access through
	virt-aa-helper.  Qemu will be creating a randomly named file under the
	mountpoint and unlinking it as soon as it has mmap()d it, therefore we
	cannot predict the full pathname, but for the same reason it is generally
	safe to provide access to $path/**.

2012-12-12  Eric Blake  <eblake@redhat.com>

	maint: mention when HACKING is rebuilt during make
	I noticed that on Fedora 18, xlstproc decides to regenerate
	HACKING with additional whitespace.  I haven't figured out why
	that is happening (although fixing it would probably be a task
	for xlstproc), but in the process of investigating, I noticed
	that 'make HACKING' was completely silent, for no good reason.

	* Makefile.am (gen-ChangeLog, gen-AUTHORS, NEWS)
	($(top_srcdir)/HACKING): Mention which files we are generating.

2012-12-12  Jiri Denemark  <jdenemar@redhat.com>

	docs: Document offline migration

2012-12-12  Peter Krempa  <pkrempa@redhat.com>

	qemu: reuse qemuMigrationIsAllowed when doing save and managedsave
	Save and managedsave both use migration to file. This patch reuses
	qemuMigrationIsAllowed to check if the migration could happen before
	trying.

	qemu: snapshot: Report better error message if migration isn't allowed
	Qemu doesn't support migration on guests with host devices. This patch
	adds a check to ensure migration is safe before actually doing so.

	qemu: Make qemuMigrationIsAllowed more reusable
	This patch exports qemuMigrationIsAllowed and adds a new parameter to it
	to denote if it's a remote migration or a local migration. Local
	migrations are used in snapshots and saving of the machine state and
	have fewer restrictions. This patch also adjusts callers of the function
	and tweaks some error messages to be more universal.

2012-12-12  Ján Tomko  <jtomko@redhat.com>

	qemu: assume seccomp sandbox is supported since qemu 1.2
	Currently there is no way to detect it via QMP and requesting "-sandbox
	off" works correctly even if it was compiled out, so this will work
	unless someone both requests the sandbox in qemu.conf and builds QEMU
	without the support for it.

2012-12-12  Michal Privoznik  <mprivozn@redhat.com>

	domain: Keep assigned class_id in domstatus XML
	Interfaces keeps a class_id, which is an ID from which bridge
	part of QoS settings is derived. We need to store class_id
	in domain status file, so we can later pass it to
	virNetDevBandwidthUnplug.

	network: Create real network status files
	Currently, we are only keeping a inactive XML configuration
	in status dir. This is no longer enough as we need to keep
	this class_id attribute so we don't overwrite old entries
	when the daemon restarts. However, since there has already
	been release which has just <network/> as root element,
	and we want to keep things compatible, detect that loaded
	status file is older one, and don't scream about it.

	bandwidth: Create network bandwidth (un)plug functions
	Network should be notified if we plug in or unplug an
	interface, so it can perform some action, e.g. set/unset
	network part of QoS. However, we are doing this in very
	early stage, so iface->ifname isn't filled in yet. So
	whenever we want to report an error, we must use a different
	identifier, e.g. the MAC address.

	bandwidth: Create rate update function
	This will be used whenever a NIC with guaranteed throughput is to
	be plugged into a bridge. It will adjust the average throughput of
	non guaranteed NICs (classid 1:2) to meet new requirements.

	bandwidth: Create (un)plug functions
	These set bridge part of QoS when bringing domain's interface up.
	Long story short, if there's a 'floor' set, a new QoS class is created.
	ClassID MUST be unique within the bridge and should be kept for
	unplug phase.

	bandwidth: Create hierarchical shaping classes
	These classes can borrow unused bandwidth. Basically,
	only egress qdsics can have classes, therefore we can
	do this kind of traffic shaping only on host's outgoing,
	that is domain's incoming traffic.

2012-12-12  Michal Privoznik  <mprivozn@redhat.com>

	bandwidth: add new 'floor' attribute
	This is however supported only on domain interfaces with
	type='network'. Moreover, target network needs to have at least
	inbound QoS set. This is required by hierarchical traffic shaping.

	From now on, the required attribute for <inbound/> is either 'average'
	(old) or 'floor' (new). This new attribute can be used just for
	interfaces type of network (<interface type='network'/>) currently.

2012-12-12  Michal Privoznik  <mprivozn@redhat.com>

	bandwidth: Attach sfq to leaf node
	Stochastic Fairness Queuing (SFQ) is queuing discipline
	(qdisc) which doesn't really shape any traffic but 'just'
	re-arrange packets in sending buffer so no stream starve.
	The goal is to ensure fairness. There is basically only one
	configuration parameter (perturb) which is set to advised
	value of 10.

	parallels: handle network adapters of type 'routed'
	Network adapters of type 'routed' is a special case. Other adapters
	have 'network' parameter in prlctl's output instead.

	Routed network adapters should be connected to 'routed' network
	from libvirt's view.

2012-12-11  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: add routed pseudo network
	Historically if traffic from the adapter is routed to LAN without
	NAT, it isn't connected to any virtual networks, but has a 'type'
	instead. Sinse libvirt has special virtual network type for such case,
	let's add pseudo network 'routed' to fit libvirt's API well.

	parallels: parse virtual network properties
	Fill bridge name and mac for bridged network and
	DHCP server parameter for host-only network.

2012-12-11  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: add network driver
	Parallels Cloud Server uses virtual networks model for network
	configuration. It uses own tools for virtual network management.
	So add network driver, which will be responsible for listing
	virtual networks and performing different operations on them
	(in consequent patched).

	This patch only allows listing virtual network names, without
	any parameters like DHCP server settings.

2012-12-11  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: move parallelsParseError to parallels_utils.h
	This macro will be used in another file in the next
	patch, so move it to common header file.

2012-12-11  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: add support of network interfaces to parallelsDomainDefineXML
	Allow changing network interfaces in domain configuration.

	ifname is used as iterface identifier: if there is interface
	with some ifname in old config and there are no interfaces with
	such name in the new config - issue prlctl command to delete
	the network interface. And vice versa - if interface with
	some ifname exists only in new config - issue prlctl command
	to create it.

2012-12-11  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: parse information about network interfaces

	network: put dnsmasq parameters in conf-file instead of command line
	This patch changes how parameters are passed to dnsmasq.  Instead of
	being on the command line, the parameters are put into a file (one
	parameter per line) and a commandline --conf-file= specifies the
	location of the file.  The file is located in the same directory as
	the leases file.

	Putting the dnsmasq parameters into a configuration file
	allows them to be examined and more easily understood than
	examining the command lines displayed by "ps ax".  This is
	especially true when a number of networks have been started.

	When the use of dnsmasq was originally done, the required command line
	was simple, but it has gotten more complicated over time and will
	likely become even more complicated in the future.

	Note: The test conf files have all been renamed .conf instead of
	.argv, and tests/networkxml2xmlargvdata was moved to
	tests/networkxml2xmlconfdata.

	network: add support for DHCPv6
	The DHCPv6 support includes IPV6 dhcp-range and dhcp-host for one
	IPv6 subnetwork on one interface.  This support will only work
	if dnsmasq version >= 2.64; otherwise an error occurs if
	dhcp-range or dhcp-host is specified for an IPv6 address.

	Essentially, this change provides the same DHCP support for IPv6
	that has been available for IPv4.

	With dnsmasq >= 2.64, support for the RA service is also now provided
	by dnsmasq (radvd is no longer used/started). (Although at least one
	version of dnsmasq prior to 2.64 "supported" IPv6 Router
	Advertisement, there were bugs (fixed in 2.64) that rendered it
	unusable.)

	Documentation and the network schema has been updated
	to reflect the new support.

	conf: split <forward> parser/clear into separate functions
	virNetworkDefUpdateForward requires separate functions to parse and
	clear a virNetworkForwardDef by itself, but they were previously just
	inlined in the virNetworkDef parse and free functions. This patch
	makes them into separate functions.

2012-12-11  Laine Stump  <laine@laine.org>

	conf: put data for network <forward> element into its own struct
	The attributes of a <network> element's <forward> element were
	previously stored directly in the virNetworkDef object, but
	virNetworkUpdateForward() needs to operate on a <forward> in
	isolation, so this patchs pulls out all those attributes into a
	separate virNetworkForwardDef struct (and shortens their names
	appropriately). This new object is contained in the virNetworkDef, not
	pointed to by it, so there is no extra memory management.

	This patch makes no functional changes, it only changes, e.g.,
	"nForwardIfs" to "forward.nifs".

	network: backend functions for updating network dns host/srv/txt
	These three functions are very similar - none allow a MODIFY
	operation; you can only add or delete.

	The biggest difference between them (other than the data itself) is in
	the criteria for determining a match, and whether or not multiple
	matches are possible:

	1) for HOST records, it's considered a match if the IP address or any
	of the hostnames of an existing record matches.

	2) for SRV records, it's a match if all of
	domain+service+protocol+target *which have been specified* are
	matched.

	3) for TXT records, there is only a single field to match - name
	(value can be the same for multiple records, and isn't considered a
	search term), so by definition there can be no ambiguous matches.

	In all three cases, if any matches are found, ADD will fail; if
	multiple matches are found, it means the search term was ambiguous,
	and a DELETE will fail.

	The upper level code in bridge_driver.c is already implemented for
	these functions - appropriate conf files will be re-written, and
	dnsmasq will be SIGHUPed or restarted as appropriate.

2012-12-11  Laine Stump  <laine@laine.org>

	conf: clear and parse functions for dns host/srv/txt records
	Since there is only a single virNetworkDNSDef for any virNetworkDef,
	and it's trivial to determine whether or not it contains any real
	data, it's much simpler (and fits more uniformly with the parse
	function calling sequence of the parsers for many other objects that
	are subordinates of virNetworkDef) if virNetworkDef *contains* an
	virNetworkDNSDef rather than pointing to one.

	Since it is now just a part of another object rather than its own
	object, it no longer makes sense to have a *Free() function, so that
	is changed to a *Clear() function.

	More importantly though, ParseXML and Clear functions are needed for
	the individual items contained in a virNetworkDNSDef (srv, txt, and
	host records), but none of them have a *Clear(), and only two of the
	three had *ParseXML() functions (both of which used a non-uniform
	arglist). Those problems are cleared up by this patch - it splits the
	higher-level Clear function into separate functions for each of the
	three, creates a parse for txt records, and cleans up the srv and host
	parsers, so we now have all the utility functions necessary to
	implement virNetworkDefUpdateDNS(Host|Srv|Txt).

2012-12-11  Laine Stump  <laine@laine.org>

	conf: rename network dns host/srv/txt arrays
	This shortens the name of the structs for srv and txt, and their
	instances in virNetworkDNSDef, to be more compact and uniform with the
	naming of the dns host array. It also changes the type of ntxts, etc
	from unsigned int to size_t, so that they can be used directly as args
	to VIR_*_ELEMENT.

	conf: use VIR_(INSERT|DELETE)_ELEMENT in virNetworkUpdate backend
	The already-written backend functions for virNetworkUpdate that add
	and delete items into lists within the a network were already debugged
	to work properly, but future such functions will use
	VIR_(INSERT|DELETE)_ELEMENT instead, so these are changed for
	uniformity.

2012-12-11  Laine Stump  <laine@laine.org>

	util: add VIR_(APPEND|INSERT|DELETE)_ELEMENT
	I noticed when writing the backend functions for virNetworkUpdate that
	I was repeating the same sequence of memmove, VIR_REALLOC, nXXX-- (and
	messed up the args to memmove at least once), and had seen the same
	sequence in a lot of other places, so I decided to write a few
	utility functions/macros - see the .h file for full documentation.

	The intent is to reduce the number of lines of code, but more
	importantly to eliminate the need to check the element size and
	element count arithmetic every time we need to do this (I *always*
	make at least one mistake.)

	VIR_INSERT_ELEMENT: insert one element at an arbitrary index within an
	  array of objects. The size of each object is determined
	  automatically by the macro using sizeof(*array). The new element's
	  contents are copied into the inserted space, then the original copy
	  of contents are 0'ed out (if everything else was
	  successful). Compile-time assignment and size compatibility between
	  the array and the new element is guaranteed (see explanation below
	  [*])

	VIR_INSERT_ELEMENT_COPY: identical to VIR_INSERT_ELEMENT, except that
	  the original contents of newelem are not cleared to 0 (i.e. a copy
	  is made).

	VIR_APPEND_ELEMENT: This is just a special case of VIR_INSERT_ELEMENT
	  that "inserts" one past the current last element.

	VIR_APPEND_ELEMENT_COPY: identical to VIR_APPEND_ELEMENT, except that
	  the original contents of newelem are not cleared to 0 (i.e. a copy
	  is made).

	VIR_DELETE_ELEMENT: delete one element at an arbitrary index within an
	  array of objects. It's assumed that the element being deleted is
	  already saved elsewhere (or cleared, if that's what is appropriate).

	All five of these macros have an _INPLACE variant, which skips the
	memory re-allocation of the array, assuming that the caller has
	already done it (when inserting) or will do it later (when deleting).

	Note that VIR_DELETE_ELEMENT* can return a failure, but only if an
	invalid index is given (index + amount to delete is > current array
	size), so in most cases you can safely ignore the return (that's why
	the helper function virDeleteElementsN isn't declared with
	ATTRIBUTE_RETURN_CHECK). A warning is logged if this ever happens,
	since it is surely a coding error.

	[*] One initial problem with the INSERT and APPEND macros was that,
	due to both the array pointer and newelem pointer being cast to void*
	when passing to virInsertElementsN(), any chance of type-checking was
	lost. If we were going to move in newelem with a memmove anyway, we
	would be no worse off for this. However, most current open-coded
	insert/append operations use direct struct assignment to move the new
	element into place (or just populate the new element directly) - thus
	use of the new macros would open a possibility for new usage errors
	that didn't exist before (e.g. accidentally sending &newelemptr rather
	than newelemptr - I actually did this quite a lot in my test
	conversions of existing code).

	But thanks to Eric Blake's clever thinking, I was able to modify the
	INSERT and APPEND macros so that they *do* check for both assignment
	and size compatibility of *ptr (an element in the array) and newelem
	(the element being copied into the new position of the array). This is
	done via clever use of the C89-guaranteed fact that the sizeof()
	operator must have *no* side effects (so an assignment inside sizeof()
	is checked for validity, but not actually evaluated), and the fact
	that virInsertElementsN has a "# of new elements" argument that we
	want to always be 1.

	Add support for offline migration
	Offline migration transfers inactive definition of a domain (which may

	on destination host. Currently, copying non-shared storage is not

	qemu: eliminate bogus error log when changing netdev's bridge
	This fixes a problem that showed up during testing of:

	  https://bugzilla.redhat.com/show_bug.cgi?id=881480

	Due to a logic error in the function that gets the name of the bridge
	an interface connects to, any time a bridge was specified directly
	(type='bridge') rather than indirectly (type='network'), An error
	would be logged (although the operation would then complete
	successfully):

	   Network type 6 is not supported

	The final virReportError() in the function
	qemuDomainNetGetBridgeName() was apparently avoided in the past with a
	"goto cleanup" at the end of each case, but the case of bridge somehow
	no longer has that final goto cleanup.

	The proper solution is anyway to not rely on goto's, but put the error
	log inside an else {} clause, so that it's executed only if the type
	is neither bridge nor network (in reality, this function should only
	ever be called for those two types, that's why this is an internal
	error).

	While making this change, the error message was also tuned to be more
	correct (since it's not really the type of the network, but the type
	of the interface, and it *is* otherwise supported, it's just that the
	interface type in question doesn't *have* a bridge device associated
	with it, or at least we don't know how to get it).

	by the current driver (although it's conceivable that some other
	driver might support that).

	The items that are invalid by definition, are now checked in the XML
	parser (since they will definitely *always* be wrong), and the others
	are checked in networkValidate() in the network driver (since, as
	mentioned, it's possible that some other network driver, or even this
	one, could some day support setting those).

	network: allow guest to guest IPv6 without gateway definition
	This patch adds the capability for virtual guests to do IPv6
	communication via a virtual network interface with no IPv6 (gateway)
	addresses specified.  This capability has always been enabled by
	default for IPv4, but disabled for IPv6 for security concerns, and
	because it requires the ip6tables command to be operational (which
	isn't the case on a system with the ipv6 module completely disabled).

	This patch adds a new attribute "ipv6" at the toplevel of a <network>
	object.  If ipv6='yes', the extra ip6tables rules required to permite
	inter-guest communications are added when the network is started. If
	it is 'no', or not present, those rules will not be added; thus the
	default behavior doesn't change, so there should be no compatibility
	issues with any existing installations.

	Note that virtual guests cannot communication with the virtualization
	host via this interface, because the following kernel tunable has
	been set:

	   net.ipv6.conf.<bridge_interface_name>.disable_ipv6 = 1

	This assures that the bridge interface will not have an IPv6
	link-local (fe80::) address.

	To control this behavior so that it is not enabled by default, the parameter
	ipv6='yes' on the <network> statement has been added.

	Documentation related to this patch has been updated.
	The network schema has also been updated.

	storage: Error out earlier if the volume target path already exists
	https://bugzilla.redhat.com/show_bug.cgi?id=832302

	It's odd to fall through to buildVol, and the existed file is
	removed when buildVol fails. This checks if the volume target
	path already exists in createVol. The reason for not using
	error like "Volume already exists" is that there isn't volume
	maintained by libvirt for the path until a operation like
	pool-refresh, using error like that will just cause confusion.

	spec: require dbus-daemon when using libvirtd in Fedora
	https://bugzilla.redhat.com/show_bug.cgi?id=830201

	In older Fedora, the spec file for libivrt depended on avahi, which
	included avahi-daemon, which in turn depended on dbus.  But now that
	avahi libs and avahi-daemon are (correctly) in separate pacakges,
	and since we REALLY don't want a mandatory dependency on avahi-daemon,
	and considering that our init scripts require the messagebus service
	from dbus, we need to explicitly require dbus ourselves.

	systemd: require dbus service
	https://bugzilla.redhat.com/show_bug.cgi?id=830201

	The initscript and upstart services depend on dbus starting
	before libvirtd.  When we first wrote the systemd script, we
	tried to do the same, but we depended on dbus.target (which
	does not exist) in comparison to network.target (which does
	exist), so we removed that in commit 4c7973e.  But we still
	need dbus up and running first, especially now that we want
	to support shutdown inhibition via dbus (whereas we originally
	needed dbus only for firewall control).

	http://www.freedesktop.org/software/systemd/man/systemd.target.html
	explains how a target (such as network.target) is just a collection
	of common services bundled together, and why we want network.target
	but dbus.service.

	* daemon/libvirtd.service.in (Unit): Depend on dbus starting
	first.

	Inhibit desktop shutdown while any virtual machines are running
	Use the freedesktop inhibition DBus service to prevent host
	shutdown or session logout while any VMs are running.

	Replace polling for active VMs with signalling by drivers
	Currently to deal with auto-shutdown libvirtd must periodically
	poll all stateful drivers. Thus sucks because it requires
	acquiring both the driver lock and locks on every single virtual
	machine. Instead pass in a "inhibit" callback to virStateInitialize
	which drivers can invoke whenever they want to inhibit shutdown
	due to existance of active VMs.

	Only let VM drivers block libvirtd timed shutdown
	The only important state that should prevent libvirtd shutdown
	is from running VMs. Networks, host devices, network filters
	and storage pools are all long lived resources that have no
	significant in-memory state. They should not block shutdown.

	Add iSCSI backend storage driver for ESX
	The patch adds the backend driver to support iSCSI format storage pools
	and volumes for ESX host. The mapping of ESX iSCSI specifics to Libvirt
	is as follows:

	1. ESX static iSCSI target <------> Libvirt Storage Pools
	2. ESX iSCSI LUNs          <------> Libvirt Storage Volumes.

	The above understanding is based on http://libvirt.org/storage.html.

	The operation supported on iSCSI pools includes:

	1. List storage pools & volumes.
	2. Get XML descriptor operaion on pools & volumes.
	3. Lookup operation on pools & volumes by name, UUID and path (if applicable).

	iSCSI pools does not support operations such as: Create / remove pools
	and volumes.

	qemu: support live update of an interface's filter
	Since we can't (currently) rely on the ability to provide blanket
	support for all possible network changes by calling the toplevel
	netdev hostside disconnect/connect functions (due to qemu only
	supporting a lockstep between initialization of host side and guest
	side of devices), in order to support live change of an interface's
	nwfilter we need to make a special purpose function to only call the
	nwfilter teardown and setup functions if the filter for an interface
	(or its parameters) changes. The pattern is nearly identical to that
	used to change the bridge that an interface is connected to.

	This patch was inspired by a request from Guido Winkelmann

	conf: fix virDomainNetGetActualDirect*() and BridgeName()
	This resolves:

	   https://bugzilla.redhat.com/show_bug.cgi?id=881480

	These three functions:

	  virDomainNetGetActualBridgeName
	  virDomainNetGetActualDirectDev
	  virDomainNetGetActualDirectMode

	return attributes that are in a union whose contents are interpreted
	differently depending on the actual->type and so they should only
	return non-0 when actual->type is 'bridge' (in the first case) or
	'direct' (in the other two cases, but I had neglected to do that, so
	...DirectDev() was returning bridge.brname (which happens to share the
	same spot in the union with direct.linkdev) if actual->type was
	'bridge', and ...BridgeName was returning direct.linkdev when
	actual->type was 'direct'.

	How does this involve Bug 881480 (which was about the inability to
	switch between two networks that both have "<forward mode='bridge'/>
	<bridge name='xxx'/>"? Whenever the return value of
	virDomainNetGetActualDirectDev() for the new and old network
	definitions doesn't match, qemuDomainChangeNet() requires a "complete
	reconnect" of the device, which qemu currently doesn't
	support. ...DirectDev() *should* have been returning NULL for old and
	new, but was instead returning the old and new bridge names, which
	differ.

	(The other two functions weren't causing any behavioral problems in
	virDomainChangeNet(), but their problem and fix was identical, so I
	included them in this same patch).

	Add support for shutdown / reboot APIs in LXC driver
	Add support for doing controlled shutdown / reboot in the LXC

	inside the container's virtual root (/proc/$INITPID/root). This
	works with sysvinit or systemd. If that file does not exist
	then send SIGTERM (for shutdown) or SIGHUP (for reboot). These

	Introduce two new methods for triggering controlled shutdown/reboot
	The virDomainShutdownFlags and virDomainReboot APIs allow the caller
	to request the operation is implemented via either acpi button press
	or a guest agent. For containers, a couple of other methods make
	sense, a message to /dev/initctl, and direct kill(SIGTERM|HUP) of
	the container init process.

	Move reboot/shutdown flags combination check into QEMU driver
	The fact that only the guest agent, or ACPI flag can be used
	when requesting reboot/shutdown is merely a limitation of the
	QEMU driver impl at this time. Thus it should not be in
	libvirt.c code

	Add APIs for talking to init via /dev/initctl
	To be able todo controlled shutdown/reboot of containers an

	qemu: don't attempt undefined QMP commands
	https://bugzilla.redhat.com/show_bug.cgi?id=872292

	Libvirt should not attempt to call a QMP command that has not been
	documented in qemu.git - if future qemu introduces a command by the
	same name but with subtly different semantics, then libvirt will be
	broken when trying to use that command.

	We also had some code that could never be reached - some of our
	commands have an alternate for new vs. old qemu HMP commands; but
	if we are new enough to support QMP, we only need a fallback to
	the new HMP counterpart, and don't need to try for a QMP counterpart
	for the old HMP version.

	See also this attempt to convert the three snapshot commands to QMP:
	https://lists.gnu.org/archive/html/qemu-devel/2012-07/msg01597.html
	although it looks like that will still not happen before qemu 1.3.

	storage: fix scsi detach regression with cgroup ACLs
	https://bugzilla.redhat.com/show_bug.cgi?id=876828

	Commit 38c4a9cc introduced a regression in hot unplugging of disks
	from qemu, where cgroup device ACLs were no longer being revoked
	(thankfully not a security hole: cgroup ACLs only prevent open()
	of the disk; so reverting the ACL prevents future abuse but doesn't
	stop abuse from an fd that was already opened before the ACL change).

	Commit 1b2ebf95 overlooked that there were two spots affected.

	* src/qemu/qemu_hotplug.c (qemuDomainDetachDiskDevice):
	Transfer backing chain before deletion.
	* src/qemu/qemu_driver.c (qemuDomainDetachDeviceDiskLive): Fix
	spacing (partly to ensure a different-looking patch).

	network: use dnsmasq --bind-dynamic when available
	This bug resolves CVE-2012-3411, which is described in the following
	bugzilla report:

	  https://bugzilla.redhat.com/show_bug.cgi?id=833033

	The following report is specifically for libvirt on Fedora:

	  https://bugzilla.redhat.com/show_bug.cgi?id=874702

	In short, a dnsmasq instance run with the intention of listening for
	DHCP/DNS requests only on a libvirt virtual network (which is
	constructed using a Linux host bridge) would also answer queries sent
	from outside the virtualization host.

	This patch takes advantage of a new dnsmasq option "--bind-dynamic",
	which will cause the listening socket to be setup such that it will
	only receive those requests that actually come in via the bridge
	interface. In order for this behavior to actually occur, not only must
	"--bind-interfaces" be replaced with "--bind-dynamic", but also all
	"--listen-address" options must be replaced with a single
	"--interface" option. Fully:

	   --bind-interfaces --except-interface lo --listen-address x.x.x.x ...

	(with --listen-address possibly repeated) is replaced with:

	   --bind-dynamic --interface virbrX

	Of course libvirt can't use this new option if the host's dnsmasq
	doesn't have it, but we still want libvirt to function (because the
	great majority of libvirt installations, which only have mode='nat'
	networks using RFC1918 private address ranges (e.g. 192.168.122.0/24),
	are immune to this vulnerability from anywhere beyond the local subnet
	of the host), so we use the new dnsmasqCaps API to check if dnsmasq
	supports the new option and, if not, we use the "old" option style
	instead. In order to assure that this permissiveness doesn't lead to a
	vulnerable system, we do check for non-private addresses in this case,
	and refuse to start the network if both a) we are using the old-style
	options, and b) the network has a publicly routable IP
	address. Hopefully this will provide the proper balance of not being
	disruptive to those not practically affected, and making sure that
	those who *are* affected get their dnsmasq upgraded.

	(--bind-dynamic was added to dnsmasq in upstream commit
	54dd393f3938fc0c19088fbd319b95e37d81a2b0, which was included in
	dnsmasq-2.63)

	util: new virSocketAddrIsPrivate function
	This new function returns true if the given address is in the range of
	any "private" or "local" networks as defined in RFC1918 (IPv4) or
	RFC3484/RFC4193 (IPv6), otherwise they return false.

	These ranges are:

	   192.168.0.0/16
	   172.16.0.0/16
	   10.0.0.0/24

	util: capabilities detection for dnsmasq
	In order to optionally take advantage of new features in dnsmasq when
	the host's version of dnsmasq supports them, but still be able to run
	on hosts that don't support the new features, we need to be able to
	detect the version of dnsmasq running on the host, and possibly
	determine from the help output what options are in this dnsmasq.

	This patch implements a greatly simplified version of the capabilities
	code we already have for qemu. A dnsmasqCaps device can be created and
	populated either from running a program on disk, reading a file with
	the concatenated output of "dnsmasq --version; dnsmasq --help", or
	examining a buffer in memory that contains the concatenated output of
	those two commands. Simple functions to retrieve capabilities flags,
	the version number, and the path of the binary are also included.

	bridge_driver.c creates a single dnsmasqCaps object at driver startup,
	and disposes of it at driver shutdown. Any time it must be used, the
	dnsmasqCapsRefresh method is called - it checks the mtime of the
	binary, and re-runs the checks if the binary has changed.

	networkxml2argvtest.c creates 2 "artificial" dnsmasqCaps objects at
	startup - one "restricted" (doesn't support --bind-dynamic) and one
	"full" (does support --bind-dynamic). Some of the test cases use one
	and some the other, to make sure both code pathes are tested.

	network: fix crash when portgroup has no name
	This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=879473

	The name attribute is required for portgroup elements (yes, the RNG
	specifies that), and there is code in libvirt that assumes it is
	non-null.  Unfortunately, the portgroup parsing function wasn't
	checking for lack of portgroup. One adverse result of this was that
	attempts to update a network by adding a portgroup with no name would
	cause libvirtd to segfault. For example:

	qemu: Fix QMP Capabability Probing Failure
	QMP Capability probing will fail if QEMU cannot bind to the

	That's because the child process is stripped of all
	capabilities and this directory is chown'ed to the configured
	QEMU user/group (normally qemu:qemu) by the QEMU driver.

	To prevent this from happening, the driver startup will now pass
	the QEMU uid and gid down to the capability probing code.
	All capability probing invocations of QEMU will be run with
	the configured QEMU uid instead of libvirtd's.

	Furter, the pid file handling is moved to libvirt, as QEMU
	cannot write to the qemu_driver->runDir (root:root). This also
	means that the libvirt daemonizing must be used.

	errors, but when checking the exit status for non-zero exit
	code no error is reported

	Ensure transient def is removed if LXC start fails
	When starting a container, newDef is initialized to a
	copy of 'def', but when startup fails newDef is never
	removed. This cause later attempts to use 'virDomainDefine'
	to lose the new data being defined.

	Ensure failure to create macvtap device aborts LXC start
	A mistaken initialization of 'ret' caused failure to create
	macvtap devices to be ignored. The libvirt_lxc process
	would later fail to start due to missing devices

	Also make sure code checks '< 0' and not '!= 0' since only
	-1 is considered an error condition

2012-11-28  Daniel P. Berrange  <berrange@redhat.com>

	Avoid crash when LXC start fails with no interface target
	If the <interface> device did not contain any <target>
	element, LXC would crash on a NULL pointer if starting
	the container failed

	Specify name of target interface with macvlan error
	When failing to create a macvlan interface, make sure the
	error message contains the name of the host interface

	Treat missing driver cgroup as fatal in LXC driver
	The LXC driver relies on use of cgroups to kill off LXC processes
	in shutdown. If cgroups aren't available, we're unable to kill
	off processes, so we must treat lack of cgroups as a fatal startup
	error.

2012-11-28  Daniel P. Berrange  <berrange@redhat.com>

	Ensure LXC container exits if cgroups setup fails
	The code setting up LXC cgroups used an 'rc' variable both
	for capturing the return value of methods it calls, and
	its own return status. The result was that several failures
	in setting up cgroups would actually result in success being
	returned.

	Use a separate 'ret' for tracking return value as per normal
	code design in other parts of libvirt

	Store initpid in the domain status XML for LXC
	The initpid will be required long term to enable LXC to
	implement various hotplug operations. Thus it needs to be
	persisted in the domain status XML. LXC has not used the
	domain status XML before, so this introduces use of the
	helpers.

	Remove bogus newline at end of debug log message

	Pass virSecurityManagerPtr object further down into LXC setup code
	Currently the lxcContainerSetupMounts method uses the
	virSecurityManagerPtr instance to obtain the mount options
	string and then only passes the string down into methods
	it calls. As functionality in LXC grows though, those
	methods need to have direct access to the virSecurityManagerPtr
	instance. So push the code down a level.

	Fix error handling in virSecurityManagerGetMountOptions
	The impls of virSecurityManagerGetMountOptions had no way to
	return errors, since the code was treating 'NULL' as a success
	value. This is somewhat pointless, since the calling code did
	not want NULL in the first place and has to translate it into
	the empty string "". So change the code so that the impls can
	return "" directly, allowing use of NULL for error reporting
	once again

	storage: fix device detach regression with cgroup ACLs
	https://bugzilla.redhat.com/show_bug.cgi?id=876828

	Commit 38c4a9cc introduced a regression in hot unplugging of disks
	from qemu, where cgroup device ACLs were no longer being revoked
	(thankfully not a security hole: cgroup ACLs only prevent open()
	of the disk; so reverting the ACL prevents future abuse but doesn't
	stop abuse from an fd that was already opened before the ACL change).

	The actual regression is due to a latent bug.  The hot unplug code
	was computing the set of files needing cgroup ACL revocation based
	on the XML passed in by the user, rather than based on the domain's
	details on which disk was being deleted.  As long as the revoke
	path was always recomputing the backing chain, this didn't really
	matter; but now that we want to compute the chain exactly once and
	remember that computation, we need to hang on to the backing chain
	until after the revoke has happened.

	* src/qemu/qemu_hotplug.c (qemuDomainDetachPciDiskDevice):
	Transfer backing chain before deletion.

	tests: Add tests for gluster protocol based network disks support

	qemu: Add support for gluster protocol based network storage backend.
	Qemu accepts gluster protocol as supported storage backend beside others.

2012-11-27  Harsh Prateek Bora  <harsh@linux.vnet.ibm.com>

	Add Gluster protocol as supported network disk backend
	This patch introduces the RNG schema and updates necessary data strucutures
	to allow various hypervisors to make use of Gluster protocol as one of the
	supported network disk backend. Next patch will add support to make use of
	this feature in Qemu since it now supports Gluster protocol as one of the
	network based storage backend.

	Two new optional attributes for <host> element are introduced - 'transport'
	and 'socket'. Valid transport values are tcp, unix or rdma. If none specified,
	tcp is assumed. If transport is unix, socket specifies path to unix socket.

	This patch allows users to specify disks on gluster backends like this:

	    <disk type='network' device='disk'>
	      <driver name='qemu' type='raw'/>
	      <source protocol='gluster' name='Volume1/image'>
	        <host name='example.org' port='6000' transport='tcp'/>
	      </source>
	      <target dev='vda' bus='virtio'/>
	    </disk>

	    <disk type='network' device='disk'>
	      <driver name='qemu' type='raw'/>
	      <source protocol='gluster' name='Volume2/image'>
	        <host transport='unix' socket='/path/to/sock'/>

	Refactor ESX storage driver to implement facade pattern
	The patch refactors the current ESX storage driver due to following reasons:

	1. Given most of the public APIs exposed by the storage driver in Libvirt
	remains same, ESX storage driver should not implement logic specific
	for only one supported format (current implementation only supports VMFS).
	2. Decoupling interface from specific storage implementation gives us an
	extensible design to hook implementation for other supported storage
	formats.

	This patch refactors the current driver to implement it as a facade pattern i.e.
	the driver exposes all the public libvirt APIs, but uses backend drivers to get
	the required task done. The backend drivers provide implementation specific to
	the type of storage device.

	Add private data pointer to virStoragePool and virStorageVol
	This will simplify the refactoring of the ESX storage driver to support
	a VMFS and an iSCSI backend.

	One of the tasks the storage driver needs to do is to decide which backend
	driver needs to be invoked for a given request. This approach extends
	virStoragePool and virStorageVol to store extra parameters:

	1. privateData: stores pointer to respective backend storage driver.
	2. privateDataFreeFunc: stores cleanup function pointer.

	virGetStoragePool and virGetStorageVol are modfied to accept these extra
	parameters as user params. virStoragePoolDispose and virStorageVolDispose
	checks for cleanup operation if available.

	The private data pointer allows the ESX storage driver to store a pointer
	to the used backend with each storage pool and volume. This avoids the need
	to detect the correct backend in each storage driver function call.

	Fix exiting of libvirt_lxc program on container quit
	The virLXCControllerClientCloseHook method was mistakenly
	assuming that the private data associated with the network

	Log an audit message with the LXC init pid
	Currently the LXC driver logs audit messages when a container

	processes /inside/ the container, we need to include the
	container init process PID.

	We can't do this in the main 'start' audit message, since
	the init PID is not available at that point. Instead we output
	a completely new audit record, that lists both PIDs.

	The LXC controller code currently directly invokes the

	The result is that when libvirtd is stopped, the
	libvirt_lxc controller process gets stuck in a I/O loop.

	to the controller and thus kills off the entire domain.

	qemu: allow larger discrepency between memory & currentMemory in domain xml
	This resolves:

	  https://bugzilla.redhat.com/show_bug.cgi?id=873134

	The reported problem is that an attempt to restore a saved domain that
	was configured with <currentMemory> and <memory> set to some (same for
	both) number that's not a multiple of 4096KiB results in an error like
	this:

	  error: Failed to start domain libvirt_test_api
	  error: XML error: current memory '4001792k' exceeds maximum '4000768k'

	(in this case, currentMemory was set to 4000000KiB).

	The reason for this failure is:

	1) a saved image contains the "live xml" of the domain at the time of
	the save.

	2) the live xml of a running domain gets its currentMemory
	(a.k.a. cur_balloon) directly from the qemu monitor rather than from
	the configuration of the domain.

	3) the value reported by qemu is (sometimes) not exactly what was
	originally given to qemu when the domain was started, but is rounded
	up to [some indeterminate granularity] - in some versions of qemu that
	granularity is apparently 1MiB, and in others it is 4MiB.

	4) When the XML is parsed to setup the state of the restored domain,
	the XML parser for <currentMemory> compares it to <memory> (which is
	the maximum allowed memory size for the domain) and if <currentMemory>
	is greater than the next 1024KiB boundary above <memory>, it spits out
	an error and fails.

	For example (from the BZ) if you start qemu on RHEL6 with both
	<currentMemory> and <memory> of 4000000 (this number is in KiB),
	libvirt's dominfo or dumpxml will report "4001792" back (rounded up to
	next 4MiB) for 10-20 seconds after the start, then revert to reporting
	"4000000". On Fedora 16 (which uses qemu-1.0), it will instead report
	"4000768" (rounded up to next 1MiB). On Fedora 17 (qemu-1.2), it seems
	to always report "4000000". ("4000000" is of course okay, and
	"4000768" is also okay since that's the next 1024KiB boundary above
	"4000000" and the parser was already allowing for that. But "4001792
	is *not* okay and produces the error message.)

	This patch solves the problem by changing the allowed "fudge factor"
	when parsing from 1024KiB to 4096KiB to match the maximum up-rounding
	that could be done in qemu.

	snapshot: require user to supply external memory file name
	For disk snapshots, the user could request an external snapshot
	but not supply a filename; later on, we would check this condition

	external memory file names, we have no later code point that was
	checking for NULL, so we should forbid this up front.

	Use helper functions to format the journal iov array
	This simplifies the top-level code, at the cost of using a little more
	stack space.  The primary benefit is being able to send more fields
	without knowing in advance how many of them, and of which types, these
	fields will be, and without having to individually add buffer variables.

	The code imposes an upper limit on the total number of iovs/buffers
	used, and fields that wouldn't fit are silently dropped.  This is not

	Add a metadata parameter to virLog{, V}Message

	The metadata representation is as minimal as possible, but requires

	The alternative of using varargs in the virLogMessage() callers:
	* Would not allow the caller to optionally omit some metadata elements,
	  except by having two calls to virLogMessage.
	* Would not be as type-safe (e.g. using int vs. size_t), and the compiler
	  wouldn't be able to do type checking
	* Depending on parameter order:
	  a) virLogMessage(..., message format, message params...,
	                   metadata..., NULL)
	     can not be portably implemented (parse_printf_format() is a glibc

	capabilities: defaultConsoleTargetType can depend on architecture
	For S390, the default console target type cannot be of type 'serial'.
	It is necessary to at least interpret the 'arch' attribute
	value of the os/type element to produce the correct default type.

	Therefore we need to extend the signature of defaultConsoleTargetType
	to account for architecture. As a consequence all the drivers
	supporting this capability function must be updated.

	Despite the amount of changed files, the only change in behavior is
	that for S390 the default console target type will be 'virtio'.

	N.B.: A more future-proof approach could be to to use hypervisor
	specific capabilities to determine the best possible console type.
	For instance one could add an opaque private data pointer to the
	virCaps structure (in case of QEMU to hold capsCache) which could
	then be passed to the defaultConsoleTargetType callback to determine
	the console target type.
	Seems to be however a bit overengineered for the use case...

	qemu: Fix domain ID numbering race condition
	When the libvirt daemon is restarted it tries to reconnect to running
	qemu domains. Since commit d38897a5d4b1880e1998394b2a37bba979bbdff1 the
	re-connection code runs in separate threads. In the original
	implementation the maximum of domain ID's (that is used as an
	initializer for numbering guests created next) while libvirt was
	reconnecting to the guest.

	With the threaded implementation this opens a possibility for race
	conditions with the thread that is autostarting guests. When there's a
	guest running with id 1 and the daemon is restarted. The autostart code
	is reached first and spawns the first guest that should be autostarted
	as id 1. This results into the following unwanted situation:

	 # virsh list
	   Id    Name                           State
	  ----------------------------------------------------
	   1     guest1                         running
	   1     guest2                         running

	This patch extracts the detection code before the re-connection threads
	are started so that the maximum id of the guests being reconnected to is
	known.

	The only semantic change created by this is if the guest with greatest ID
	quits before we are able to reconnect it's ID is used anyway as the
	greatest one as without this patch the greatest ID of a process we could
	successfuly reconnect to would be used.

	As a bonus, the testsuite was already testing snapshot parsing, so
	the fact that the test still passes means that we are now giving
	testsuite exposure to vshStringToArray.

	snapshot: qemu: Add async job type for snapshots
	The new external system checkpoints will require an async job while the

	snapshot: Add flag to enable creating checkpoints in live state
	The default behavior while creating external checkpoints is to pause the
	guest while the memory state is captured. We want the users to sacrifice
	space saving for creating the memory save image while the guest is live
	to minimize downtime.

	This patch adds a flag that causes the guest not to be paused before
	taking the snapshot.

	qemu: Split out domain memory saving code to allow reuse
	The code that saves domain memory by migration to file can be reused
	while doing external checkpoints of a machine. This patch extracts the
	common code and places it in a separate function.

	qemu: Clean up snapshot retrieval to use the new helper
	Two other places were left with the old code to look up snapshots.
	Change them to use the snapshot lookup helper.

	cpu: Add AMD Opteron G5 cpu model

	cpu: Add newly added cpu flags
	This patch adds a few new processor feature flags. Namely:
	 f16c rdrand lwp tbm topoext perfctr_core perfctr_nb fsgsbase bmi1 hle
	 avx2 bmi2 erms invpcid rtm rdseed adx tce

	qemu: Fix possible race when pausing guest
	When pausing the guest while migration is running (to speed up
	convergence) the virDomainSuspend API checks if the migration job is
	active before entering the job. This could cause a possible race if the
	virDomainSuspend is called while the job is active but ends before the
	Suspend API enters the job (this would require that the migration is
	aborted). This would cause a incorrect event to be emitted.

	snapshot: merge pre-snapshot checks
	Both system checkpoint snapshots and disk snapshots were iterating
	over all disks, doing a final sanity check before doing any work.
	But since future patches will allow offline snapshots to be either
	external or internal, it makes sense to share the pass over all
	disks, and then relax restrictions in that pass as new modes are
	implemented.  Future patches can then handle external disks when
	the domain is offline, then handle offline --disk-snapshot, and
	finally, combine with migration to file to gain a complete external
	system checkpoint snapshot of an active domain without using 'savevm'.

	* src/qemu/qemu_driver.c (qemuDomainSnapshotDiskPrepare)
	(qemuDomainSnapshotIsAllowed): Merge...
	(qemuDomainSnapshotPrepare): ...into one function.
	(qemuDomainSnapshotCreateXML): Update caller.

2012-11-03  Eric Blake  <eblake@redhat.com>

	snapshot: populate new XML info for qemu snapshots
	Now that the XML supports listing internal snapshots, it is worth

	parse disk info and set memory info.

2012-11-03  Eric Blake  <eblake@redhat.com>

	snapshot: improve disk align checking
	There were not previous callers with require_match set to true.
	I originally implemented this bool with the intent of supporting
	ESX snapshot semantics, where the choice of internal vs. external
	vs. non-checkpointable must be made at domain start, but as ESX
	has not been wired up to use it yet, we might as well fix it to
	work with our next qemu patch for now, and worry about any further
	improvements (changing the bool to a flags argument) if the ESX
	driver decides to use this function in the future.

	* src/conf/snapshot_conf.c (virDomainSnapshotAlignDisks): Alter
	logic when require_match is true to deal with new XML.

2012-11-02  Eric Blake  <eblake@redhat.com>

	snapshot: new XML for external system checkpoint
	Each <domainsnapshot> can now contain an optional <memory>
	element that describes how the VM state was handled, similar
	to disk snapshots.  The new element will always appear in
	output; for back-compat, an input that lacks the element will
	assume 'no' or 'internal' according to the domain state.

	Along with this change, it is now possible to pass <disks> in
	the XML for an offline snapshot; this also needs to be wired up
	in a future patch, to make it possible to choose internal vs.
	external on a per-disk basis for each disk in an offline domain.
	At that point, using the --disk-only flag for an offline domain
	will be able to work.

	For some examples below, remember that qemu supports the
	following snapshot actions:

	qemu-img: offline external and internal disk
	savevm: online internal VM and disk
	migrate: online external VM
	transaction: online external disk

	=====
	<domainsnapshot>
	  <memory snapshot='no'/>
	  ...
	</domainsnapshot>

	implies that there is no VM state saved (mandatory for
	offline and disk-only snapshots, not possible otherwise);
	using qemu-img for offline domains and transaction for online.

	=====
	<domainsnapshot>
	  <memory snapshot='internal'/>
	  ...
	</domainsnapshot>

	state is saved inside one of the disks (as in qemu's 'savevm'
	system checkpoint implementation).  If needed in the future,
	we can also add an attribute pointing out _which_ disk saved
	the internal state; maybe disk='vda'.

	=====
	<domainsnapshot>
	  <memory snapshot='external' file='/path/to/state'/>
	  ...
	</domainsnapshot>

	This is not wired up yet, but future patches will allow this to
	control a combination of 'virsh save /path/to/state' plus disk
	snapshots from the same point in time.

	=====

	So for 1.0.1 (and later, as needed), I plan to implement this table
	of combinations, with '*' designating new code and '+' designating
	existing code reached through new combinations of xml and/or the
	existing DISK_ONLY flag:

	domain  memory  disk   disk-only | result
	-----------------------------------------
	offline omit    omit   any       | memory=no disk=int, via qemu-img

2012-11-02  Daniel P. Berrange  <berrange@redhat.com>

	Document bracket whitespace rules & add syntax-check rule
	This documents the following whitespace rules

	      if(foo)   // Bad
	      if (foo)  // Good

	      int foo (int wizz)  // Bad
	      int foo(int wizz)   // Good

	      bar = foo (wizz);  // Bad
	      bar = foo(wizz);   // Good

	      typedef int (*foo) (int wizz);  // Bad
	      typedef int (*foo)(int wizz);   // Good

	      int foo( int wizz );  // Bad
	      int foo(int wizz);    // Good

	There is a syntax-check rule extension to validate all these rules.
	Checking for 'function (...args...)' is quite difficult since it
	needs to ignore valid usage with keywords like 'if (...test...)'
	and while/for/switch. It must also ignore source comments and
	quoted strings.

	It is not possible todo this with a simple regex in the normal
	syntax-check style. So a short Perl script is created instead
	to analyse the source. In practice this works well enough. The
	only thing it can't cope with is multi-line quoted strings of
	the form

	 "start of string\
	more lines\
	more line\
	the end"

	but this can and should be written as

	 "start of string"
	 "more lines"
	 "more line"
	 "the end"

	with this simple change, the bracket checking script does not
	have any false positives across libvirt source, provided it
	is only run against .c files. It is not practical to run it
	against .h files, since those use whitespace extensively to
	get alignment (though this is somewhat inconsistent and could
	arguably be fixed).

	The only limitation is that it cannot detect a violation where
	the first arg starts with a '*', eg

	   foo(*wizz);

	since this generates too many false positives on function
	typedefs which can't be supressed efficiently.

2012-11-02  Daniel P. Berrange  <berrange@redhat.com>

	Remove spurious whitespace between function name & open brackets
	The libvirt coding standard is to use 'function(...args...)'

	net: Mark network persistent when assigning persistent definition
	When assigning the new persistent definition for a transient network
	(thus making it persistent) the network needs to be marked persistent
	before actually atempting to assign the definition.

	net: Add support for changing persistent networks to transient
	Until now, the network undefine API was able to undefine only inactive
	networks. The restriction doesn't make sense any more so this patch
	implements changing networks to transient.

	net: Remove dnsmasq and radvd files also when destroying transient nets
	The network driver didn't care about config files when a network was
	destroyed, just when it was undefined leaving behind files for transient
	networks.

	This patch splits out the cleanup code to a helper function that handles
	the cleanup if the inactive network object is being removed and re-uses
	this code when getting rid of inactive networks.

	The hosts file was created in the network definition function. This
	patch moves the place the file is being created to the point where
	dnsmasq is being started.

	net: Change argument type of virNetworkObjIsDuplicate()
	The argument check_active is used only as a boolean so this patch
	changes the type and updates callers.

	conf: net: Fix deadlock if assignment of network def fails
	When the assignment fails, the network object is not unlocked and next
	call that would use it deadlocks.

	logging.c: Properly indent and ignore one syntax-check rule
	With our fix of mkostemp (pushed as 2b435c15) we define a macro
	to compile with uclibc. However, this definition is conditional
	and thus needs to be properly indented. Moreover, with this definition
	sc_prohibit_mkstemp syntax-check rule keeps yelling:

	  src/util/logging.c:63:# define mkostemp(x,y) mkstemp(x)
	  maint.mk: use mkostemp with O_CLOEXEC instead of mkstemp

	Therefore we should ignore this file for this rule.

	BZ:https://bugzilla.redhat.com/show_bug.cgi?id=871273

	In the case of BlkIoTune it is unnecessary to strip the QEMU host drive
	prefix because we operate on "info block"/"query-block" output that uses

	iohelper: fdatasync() at the end
	Currently, when we are doing (managed) save, we insert the

	iohelper. It reads data and write them into given file. However,
	with write() being asynchronous data may still be in OS
	caches and hence in some (corner) cases, all migration data
	may have been read and written (not physically though). So
	qemu will report success, as well as iohelper. However, with
	some non local filesystems, where ENOSPACE is polled every X
	time units, we may get into situation where all operations
	succeeded but data hasn't reached the disk. And in fact will
	never do. Therefore we ought sync caches to make sure data

	Make non-KVM machines work with QMP probing
	When there is no 'qemu-kvm' binary and the emulator used for a machine
	is, for example, 'qemu-system-x86_64' that, by default, runs without
	kvm enabled, libvirt still supplies '-no-kvm' option to this process,
	even though it does not recognize such option (making the start of a
	domain fail in that case).

	This patch fixes building a command-line for QEMU machines without KVM
	acceleration and is based on following assumptions:

	 - QEMU_CAPS_KVM flag means that QEMU is running KVM accelerated
	   machines by default (without explicitly requesting that using a
	   command-line option).  It is the closest to the truth according to
	   the code with the only exception being the comment next to the
	   flag, so it's fixed in this patch as well.

	 - QEMU_CAPS_ENABLE_KVM flag means that QEMU is, by default, running
	   without KVM acceleration and in case we need KVM acceleration it
	   needs to be explicitly instructed to do so.  This is partially
	   true for the past (this option essentially means that QEMU
	   recognizes the '-enable-kvm' option, even though it's almost the
	   same).

	util: do a better job of matching up pids with their binaries
	This patch resolves: https://bugzilla.redhat.com/show_bug.cgi?id=871201

	If libvirt is restarted after updating the dnsmasq or radvd packages,
	a subsequent "virsh net-destroy" will fail to kill the dnsmasq/radvd
	process.

	The problem is that when libvirtd restarts, it re-reads the dnsmasq
	and radvd pidfiles, then does a sanity check on each pid it finds,
	including checking that the symbolic link in /proc/$pid/exe actually
	points to the same file as the path used by libvirt to execute the
	binary in the first place. If this fails, libvirt assumes that the
	process is no longer alive.

	But if the original binary has been replaced, the link in /proc is set
	to "$binarypath (deleted)" (it literally has the string " (deleted)"
	appended to the link text stored in the filesystem), so even if a new
	binary exists in the same location, attempts to resolve the link will
	fail.

	In the end, not only is the old dnsmasq/radvd not terminated when the
	network is stopped, but a new dnsmasq can't be started when the
	network is later restarted (because the original process is still
	listening on the ports that the new process wants).

	The solution is, when the initial "use stat to check for identical
	inodes" check for identity between /proc/$pid/exe and $binpath fails,
	to check /proc/$pid/exe for a link ending with " (deleted)" and if so,
	truncate that part of the link and compare what's left with the
	original binarypath.

	A twist to this problem is that on systems with "merged" /sbin and
	/usr/sbin (i.e. /sbin is really just a symlink to /usr/sbin; Fedora
	17+ is an example of this), libvirt may have started the process using
	one path, but /proc/$pid/exe lists a different path (indeed, on F17
	this is the case - libvirtd uses /sbin/dnsmasq, but /proc/$pid/exe
	shows "/usr/sbin/dnsmasq"). The further bit of code to resolve this is
	to call virFileResolveAllLinks() on both the original binarypath and
	on the truncated link we read from /proc/$pid/exe, and compare the
	results.

	The resulting code still succeeds in all the same cases it did before,
	but also succeeds if the binary was deleted or replaced after it was
	started.

	build: place attributes in correct location
	Ever since commit eefb881, ATTRIBUTE_NONNULL has normally been a
	no-op under gcc (since it tends to cause more bugs than it cures
	given gcc's current lame implementation of the attribute).  However,
	the macro is still useful to Coverity and other static-analysis
	tools, but only if we use it correctly.  Coverity follows gcc's lead
	in accepting function declarations with attributes at the end, but
	function bodies must attach attributes to the return type.  That is,
	these are valid:

	void foo(void *arg) ATTRIBUTE_NONNULL(1);
	void ATTRIBUTE_NONNULL(1) foo(void *arg);
	void ATTRIBUTE_NONNULL(1) foo(void *arg) {}

	but this is not:

	void foo(void *arg) ATTRIBUTE_NONNULL(1) {}

	even though you don't get a compile failure until you do static
	analysis.  Bug introduced in commit 80533ca, with these symptoms:

	build: fix linking with systemtap probes
	Commit 34e8f63a3 altered virfile.o to drag in additional symbols,

	a link failure when systemtap probes are enabled, such as:

	./.libs/libvirt_util.a(libvirt_util_la-event_poll.o): In function `virEventPollRunOnce':
	/home/dummy/libvirt/src/util/event_poll.c:614: undefined reference to `libvirt_event_poll_run_semaphore'
	./.libs/libvirt_util.a(libvirt_util_la-event_poll.o):(.note.stapsdt+0x24): undefined reference to `libvirt_event_poll_add_handle_semaphore'

	Even though libvirt_iohelper and libvirt_parthelper don't directly
	use the portion of virfile.o that drags in probing, it was easier
	to satisfy the linker and get the build back up, than to figure out
	whether it is even possible or worth trying to disentangle the mess.

	blockjob: relabel entire existing chain
	When using block copy to pivot over to a new chain, the backing files
	for the new chain might still need labeling (particularly if the user
	passes --reuse-ext with a relative backing file name).  Relabeling a
	file that is already labeled won't hurt, so this just labels the entire
	chain at the point of the pivot.  Doing the relabel of the chain uses
	the fact that we already safely probed the file type of an external

	blockjob: allow mirroring under SELinux and cgroup
	Use the recent addition of qemuDomainPrepareDiskChainElement to

	and set the SELinux label; then audit the fact that we hand a new
	file over to qemu.  Alas, releasing the lease and label at the end
	of the mirroring is a trickier prospect (we would have to trace the
	backing chain of both source and destination, and be sure not to
	revoke rights to any part of the chain that is shared), so for now,
	virDomainBlockJobAbort still leaves things with additional access
	granted (as block-pull and block-commit have the same problem of
	not clamping access after completion, a future cleanup would cover

	blockjob: allow for existing files in block-copy

	file for its type; such an action would be a security risk if the
	existing file is supposed to be raw but the contents resemble some
	other format; however, since the virDomainBlockRebase API has a
	flag to force treating the file as raw rather than probe, we can
	assume that probing is safe in all other instances.  Besides, if
	we don't probe or force raw, then qemu will.

	flag.
	(qemuDomainBlockCopy): Wire up flag, and add some sanity checks.

2012-10-27  Eric Blake  <eblake@redhat.com>

	blockjob: implement block copy for qemu
	Minimal patch to wire up all the pieces in the previous patches
	to actually enable a block copy job.  By minimal, I mean that
	qemu creates the file (that is, no REUSE_EXT flag support yet),
	SELinux must be disabled, a lock manager is not informed, and the
	audit logs aren't updated.  But those will be added as
	improvements in future patches.

	This patch is designed so that if we ever add a future API
	virDomainBlockCopy with more bells and whistles (such as letting
	the user specify a destination image format different than the
	source), where virDomainBlockRebase is a wrapper around the
	simpler portions of the new functionality, then the new API can
	just reuse the new qemuDomainBlockCopy function and already
	support _SHALLOW and _REUSE_EXT flags.  Also note that libvirt.c
	already filtered the new flags if _COPY is not present, so that
	we are not impacting the case of BlockRebase being a wrapper
	around BlockPull.

	* src/qemu/qemu_driver.c (qemuDomainBlockCopy): New function.
	(qemuDomainBlockRebase): Call it when appropriate.

2012-10-27  Eric Blake  <eblake@redhat.com>

	blockjob: make block pivot safer
	Since libvirt drops locks between issuing a monitor command and
	getting a response, it is possible for libvirtd to be restarted
	before getting a response on a block-job-complete command; worse, it
	is also possible for the guest to shut itself down during the window
	while libvirtd is down, ending the qemu process.  A management app
	needs to know if the pivot happened (and the destination file
	contains guest contents not in the source) or failed (and the source
	file contains guest contents not in the destination), but since
	the job is finished, 'query-block-jobs' no longer tracks the
	status of the job, and if the qemu process itself has disappeared,
	even 'query-block' cannot be checked to ask qemu its current state.

	At the time of this patch, the design for persistent bitmap has not
	been clarified, so a followup patch will be needed once qemu
	actually figures out how to expose it, and we figure out how to use
	it.  In the meantime, we have a solution that avoids the worst of
	the problem.  [This problem was first analyzed with the RHEL 6.3
	__com.redhat_drive-reopen command; which partly explains why
	upstream qemu 1.3 ditched the drive-reopen idea and went with
	block-job-complete plus persistent bitmap instead.]

	If we surround 'drive-reopen' with a pause/resume pair, then we can
	guarantee that the guest cannot modify either source or destination
	files in the window of libvirtd uncertainty, and the management app
	is guaranteed that either libvirt knows the outcome and reported it
	correctly; or that on libvirtd restart, the guest will still be
	paused and that the qemu process cannot have disappeared due to
	guest shutdown; and use that as a clue that the management app must
	implement recovery protocol, with both source and destination files
	still being in sync and with 'query-block' still being an option as
	part of that recovery.  My testing shows that the pause window will
	typically be only a fraction of a second.

	* src/qemu/qemu_driver.c (qemuDomainBlockPivot): Pause around
	drive-reopen.
	(qemuDomainBlockJobImpl): Update caller.

2012-10-27  Eric Blake  <eblake@redhat.com>

	blockjob: support pivot operation on cancel
	This is the bare minimum to end a copy job (of course, until a
	later patch adds the ability to start a copy job, this patch
	doesn't do much in isolation; I've just split the patches to
	ease the review).

	This patch intentionally avoids SELinux, lock manager, and audit
	actions.  Also, if libvirtd restarts at the exact moment that a
	'block-job-complete' is in flight, the proposed proper way to
	detect the outcome of that would be with a persistent bitmap and
	some additional query commands when libvirtd restarts.  This
	patch is enough to test the common case of success when used
	correctly, while saving the subtleties of proper cleanup for
	worst-case errors for later.

	When a mirror job is started, cancelling the job safely reverts back
	to the source disk, regardless of whether the destination is in
	phase 1 (streaming, in which case the destination is worthless) or
	phase 2 (mirroring, in which case the destination is synced up to
	the source at the time of the cancel).  Our existing code does just
	fine in either phase, other than some bookkeeping cleanup; this
	implements live block copy.

	Ideas for future enhancements via new flags:

	Depending on when persistent bitmap support is added, it may be
	worth adding a VIR_DOMAIN_REBASE_COPY_ATOMIC flag that fails up
	front if we detect an older qemu with risky pivot operation.

	Interesting side note: while snapshot-create --disk-only creates a
	copy of the disk at a point in time by moving the domain on to a
	new file (the copy is the file now in the just-extended backing
	chain), blockjob --abort of a copy job creates a copy of the disk
	while keeping the domain on the original file.  There may be
	potential improvements to the snapshot code to exploit block copy
	over multiple disks all at one point in time.  And, if
	'block-job-cancel' were made part of 'transaction', you could
	copy multiple disks at the same point in time without pausing
	the domain.  This also implies we may want to add a --quiesce flag
	to virDomainBlockJobAbort, so that when breaking a mirror (whether
	by cancel or pivot), the side of the mirror that we are abandoning
	is at least in a stable state with regards to guest I/O.

2012-10-27  Eric Blake  <eblake@redhat.com>

	blockjob: react to active block copy
	For now, disk migration via block copy job is not implemented in
	libvirt.  But when we do implement it, we have to deal with the
	fact that qemu does not yet provide an easy way to re-start a qemu
	process with mirroring still intact.  Paolo has proposed an idea
	for a persistent dirty bitmap that might make this possible, but
	until that design is complete, it's hard to say what changes
	libvirt would need.  Even something like 'virDomainSave' becomes
	hairy, if you realize the implications that 'virDomainRestore'
	would be stuck with recreating the same mirror layout.

	But if we step back and look at the bigger picture, we realize that
	the initial client of live storage migration via disk mirroring is
	oVirt, which always uses transient domains, and that if a transient
	domain is destroyed while a mirror exists, oVirt can easily restart
	the storage migration by creating a new domain that visits just the
	source storage, with no loss in data.

	We can make life a lot easier by being cowards for now, forbidding
	certain operations on a domain.  This patch guarantees that we
	never get in a state where we would have to restart a domain with
	a mirroring block copy, by preventing saves, snapshots, migration,
	hot unplug of a disk in use, and conversion to a persistent domain
	(thankfully, it is still relatively easy to 'virsh undefine' a
	running domain to temporarily make it transient, run tests on
	'virsh blockcopy', then 'virsh define' to restore the persistence).
	Later, if the qemu design is enhanced, we can relax our code.

	The change to qemudDomainDefine looks a bit odd for undoing an
	assignment, rather than probing up front to avoid the assignment,
	but this is because of how virDomainAssignDef combines both a
	lookup and assignment into a single function call.

	blockjob: add qemu capabilities related to block jobs
	Upstream qemu 1.3 is adding two new monitor commands, 'drive-mirror'
	and 'block-job-complete'[1], which can drive live block copy and
	storage migration.  [Additionally, RHEL 6.3 had backported an earlier
	version of most of the same functionality, but under the names
	'__com.redhat_drive-mirror' and '__com.redhat_drive-reopen' and with
	slightly different JSON arguments, and has been using patches similar
	to these upstream patches for several months now.]

	The libvirt API virDomainBlockRebase as already committed for 0.9.12
	is flexible enough to expose the basics of block copy, but some
	additional features in the 'drive-mirror' qemu command, such as
	setting error policy, setting granularity, or using a persistent
	bitmap, may later require a new libvirt API virDomainBlockCopy.  I
	will wait to add that API until we know more about what qemu 1.3
	will finally provide.

	This patch caters only to the upstream qemu 1.3 interface, although
	I have proven that the changes for RHEL 6.3 can be isolated to
	just qemu_monitor_json.c, and the rest of this series will
	gracefully handle either interface once the JSON differences are
	papered over in a downstream patch.

	For consistency with other block job commands, libvirt must handle
	the bandwidth argument as MiB/sec from the user, even though qemu
	exposes the speed argument as bytes/sec; then again, qemu rounds
	up to cluster size internally, so using MiB hides the worst effects
	of that rounding if you pass small numbers.

	qemu: fix attach/detach of netdevs with matching mac addrs
	This resolves:

	   https://bugzilla.redhat.com/show_bug.cgi?id=862515

	which describes inconsistencies in dealing with duplicate mac
	addresses on network devices in a domain.

	(at any rate, it resolves *almost* everything, and prints out an
	informative error message for the one problem that isn't solved, but
	has a workaround.)

	A synopsis of the problems:

	1) you can't do a persistent attach-interface of a device with a mac
	address that matches an existing device.

	2) you *can* do a live attach-interface of such a device.

	3) you *can* directly edit a domain and put in two devices with
	matching mac addresses.

	4) When running virsh detach-device (live or config), only MAC address
	is checked when matching the device to remove, so the first device
	with the desired mac address will be removed. This isn't always the
	one that's wanted.

	5) when running virsh detach-interface (live or config), the only two
	items that can be specified to match against are mac address and model
	type (virtio, etc) - if multiple netdevs match both of those
	attributes, it again just finds the first one added and assumes that
	is the only match.

	Since it is completely valid to have multiple network devices with the
	same MAC address (although it can cause problems in many cases, there
	*are* valid use cases), what is needed is:

	1) remove the restriction that prohibits doing a persistent add of a
	netdev with a duplicate mac address.

	2) enhance the backend of virDomainDetachDeviceFlags to check for
	something that *is* guaranteed unique (but still work with just mac
	address, as long as it yields only a single results.

	This patch does three things:

	1) removes the check for duplicate mac address during a persistent
	netdev attach.

	2) unifies the searching for both live and config detach of netdevices
	in the subordinate functions of qemuDomainModifyDeviceFlags() to use the
	new function virDomainNetFindIdx (which matches mac address and PCI
	address if available, checking for duplicates if only mac address was
	specified). This function returns -2 if multiple matches are found,
	allowing the callers to print out an appropriate message.

	Steps 1 & 2 are enough to fully fix the problem when using virsh
	attach-device and detach-device (which require an XML description of
	the device rather than a bunch of commandline args)

	3) modifies the virsh detach-interface command to check for multiple
	matches of mac address and show an error message suggesting use of the
	detach-device command in cases where there are multiple matching mac
	addresses.

	Later we should decide how we want to input a PCI address on the virsh
	commandline, and enhance detach-interface to take a --address option,
	eliminating the need to use detach-device

	* src/conf/domain_conf.c
	* src/conf/domain_conf.h
	* src/libvirt_private.syms
	  * added new virDomainNetFindIdx function
	  * removed now unused virDomainNetIndexByMac and

	With older gcc and 64-bit size_t, the compiler issues a real warning:

	Introduced in commit 0cc79255.  Depending on machine endianness,

	We always expose individual bits from flags as separate options rather

	    Automatically enable systemd journal logging

	    Probe to see if the systemd journal is accessible, and if
	    so enable logging to the journal by default, rather than
	    stderr (current default under systemd).

	Previously  'LIBVIRT_DEBUG=1 /usr/sbin/libvirtd' would show all debug
	output to stderr, now it send debug output to the journal.

	Only use the journal by default if running in daemon mode, or
	if stdin is _not_ a tty. This should make libvirtd launched from
	systemd use the journal, but preserve the old behavior in most
	situations.

	network: fix networkValidate check for default portgroup and vlan
	This was found during testing of the fix for:

	   https://bugzilla.redhat.com/show_bug.cgi?id=868483

	networkValidate was supposed to check for the existence of multiple
	portgroups and report an error if this was encountered. It did, but
	there were two problems:

	1) even though it logged an error, it still returned success, allowing
	the operation to continue.

	2) It could exit the portgroup checking loop early (or possibly not
	even do it once) if a vlan tag was supplied in the base network config
	or one of the portgroups.

	This patch fixes networkValidate to return failure in addition to
	logging the error, and also changes it to not exit the portgroup
	checking loop early. The logic was a bit off in the checking for vlan
	anyway, and it's intertwined with fixing the early loop exit, so I
	fixed that as well. Now it correctly checks for combinations where a
	<virtualport> is specified in the base network def and <vlan> is given
	in a portgroup, as well as the opposite (<vlan> in base network def
	and <virtualport> in portgroup), and ignores the case of a disallowed
	vlan when using *no* portgroup if there is a default portgroup (since
	in that case there is no way to not use any portgroup).

	nodeinfo: improve probing node cpu bitmap
	Callers should not need to know what the name of the file to

	furthermore, qemu cares about online cpus, not present cpus,

	cpu: Add recently added cpu feature flags.
	Qemu has added some new feature flags. This patch adds them to libvirt.

	The new features are for the cpuid function 0x7 that takes an argument
	in the ecx register. Currently only 0x0 is used as the argument so I was
	lazy and I just clear the registers to 0 before calling cpuid. In future
	when there maybe will be some other possible arguments, we will need to
	improve the cpu detection code to take this into account.

	qemu: Prohibit chaning affinity of domain process if placement is 'auto'
	On one hand, numad probably will manage the affinity of domain process
	dynamically in future. On the other hand, even numad won't manage it,
	it still could confusion. Let's make things simpler enough to avoid
	the lair for now.

2012-10-24  Osier Yang  <jyang@redhat.com>

	qemu: Keep the affinity when creating cgroup for emulator thread
	When the cpu placement model is "auto", it sets the affinity for
	domain process with the advisory nodeset from numad, however,
	creating cgroup for the domain process (called emulator thread
	in some contexts) later overrides that with pinning it to all
	available pCPUs.

	How to reproduce:

	  * Configure the domain with "auto" placement for <vcpu>, e.g.
	    <vcpu placement='auto'>4</vcpu>
	  * % virsh start dom
	  * % cat /proc/$dompid/status

	Though the emulator cgroup cause conflicts, but we can't simply
	prohibit creating it, as other tunables are still useful, such
	as "emulator_period", which is used by API
	virDomainSetSchedulerParameter. So this patch doesn't prohibit
	creating the emulator cgroup, but inherit the nodeset from numad,
	and reset the affinity for domain process.

	* src/qemu/qemu_cgroup.h: Modify definition of qemuSetupCgroupForEmulator
	                          to accept the passed nodenet

	virNodeGetCPUMap: Implement wire protocol.
	- Defined the wire protocol format for virNodeGetCPUMap and its
	  arguments
	- Implemented remote method invocation (remoteNodeGetCPUMap)
	- Implemented method dispatcher (remoteDispatchNodeGetCPUMap)

2012-10-24  Viktor Mihajlovski  <mihajlov@linux.vnet.ibm.com>

	virNodeGetCPUMap: Define public API.
	Adding a new API to obtain information about the
	host node's present, online and offline CPUs.

	int virNodeGetCPUMap(virConnectPtr conn,
	                     unsigned char **cpumap,
	                     unsigned int *online,
	                     unsigned int flags);

	The function will return the number of CPUs present on the host
	or -1 on failure;
	If cpumap is non-NULL virNodeGetCPUMap will allocate an array
	containing a bit map representation of the online CPUs. It's
	the callers responsibility to deallocate cpumap using free().
	If online is non-NULL, the variable pointed to will contain
	the number of online host node CPUs.
	The variable flags has been added to support future extensions
	and must be set to 0.

	Extend the driver structure by nodeGetCPUMap entry in support of the
	new API virNodeGetCPUMap.
	Added implementation of virNodeGetCPUMap to libvirt.c

	storage: Don't do wait loops from VolLookupByPath

	On F17 at least, every time libvirtd starts we get this in syslog:

	libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory

	This comes from cyrus-sasl, and happens regardless of whether the
	gssapi plugin is requested, which is what actually uses
	/etc/libvirt/krb5.tab.

	While cyrus-sasl shouldn't complain, we can easily make it shut up by
	commenting out the keytab value by default.

	Also update the keytab comment to the more modern one from qemu's
	sasl config file.

	network: don't allow multiple default portgroups
	This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=868483

	virNetworkUpdate, virNetworkDefine, and virNetworkCreate all three
	allow network definitions to contain multiple <portgroup> elements
	with default='yes'. Only a single default portgroup should be allowed
	for each network.

	This patch updates networkValidate() (called by both
	virNetworkCreate() and virNetworkDefine()) and
	virNetworkDefUpdatePortGroup (called by virNetworkUpdate() to not
	allow multiple default portgroups.

	network: always create dnsmasq hosts and addnhosts files, even if empty
	This fixes the problem reported in:

	  https://bugzilla.redhat.com/show_bug.cgi?id=868389

	Previously, the dnsmasq hosts file (used for static dhcp entries, and
	addnhosts file (used for additional dns host entries) were only
	created/referenced on the dnsmasq commandline if there was something
	to put in them at the time the network was started. Once we can update
	a network definition while it's active (which is now possible with
	virNetworkUpdate), this is no longer a valid strategy - if there were
	0 dhcp static hosts (resulting in no reference to the hosts file on the
	commandline), then one was later added, the commandline wouldn't have
	linked dnsmasq up to the file, so even though we create it, dnsmasq
	doesn't pay any attention.

	The solution is to just always create these files and reference them
	on the dnsmasq commandline (almost always, anyway). That way dnsmasq
	can notice when a new entry is added at runtime (a SIGHUP is sent to
	dnsmasq by virNetworkUdpate whenever a host entry is added or removed)

	The exception to this is that the dhcp static hosts file isn't created
	if there are no lease ranges *and* no static hosts. This is because in
	this case dnsmasq won't be setup to listen for dhcp requests anyway -
	in that case, if the count of dhcp hosts goes from 0 to 1, dnsmasq
	will need to be restarted anyway (to get it listening on the dhcp
	port). Likewise, if the dhcp hosts count goes from 1 to 0 (and there
	are no dhcp ranges) we need to restart dnsmasq so that it will stop
	listening on port 67. These special situations are handled in the
	bridge driver's networkUpdate() by checking for ((bool)
	nranges||nhosts) both before and after the update, and triggering a
	dnsmasq restart if the before and after don't match.

	network: free/null newDef if network fails to start
	https://bugzilla.redhat.com/show_bug.cgi?id=866364

	pointed out a crash due to virNetworkObjAssignDef free'ing
	network->newDef without NULLing it afterward. A fix for this is in
	upstream commit b7e9202401ebaa039b8f05acdefda8c24081537a. While the
	NULLing of newDef was a legitimate fix, newDef should have already
	been empty (NULL) anyway (as indicated in the comment that was deleted
	by that commit).

	The reason that newDef had a non-NULL value (i.e. the root cause) was
	that networkStartNetwork() had failed after populating
	network->newDef, but then neglected to free/NULL newDef in the
	cleanup.

	(A bit of background here: network->newDef should contain the
	persistent config of a network when a network is active (and of course
	only when it is persisten), and NULL at all other times. There is also
	a network->def which should contain the persistent definition of the
	network when it is inactive, and the current live state at all other
	times. The idea is that you can make changes to network->newDef which
	will take effect the next time the network is restarted, but won't
	mess with the current state of the network (virDomainObj has a similar
	pair of virDomainDefs that behave in the same fashion). Personally I
	think there should be a network->live and network->config, and the
	location of the persistent config should *always* be in
	network->config, but that's for a later cleanup).

	Since I love things to be symmetric, I created a new function called
	virNetworkObjUnsetDefTransient(), which reverses the effects of
	virNetworkObjSetDefTransient(). I don't really like the name of the
	new function, but then I also didn't really like the name of the old
	one either (it's just named that way to match a similar function in
	the domain conf code).

	blockjob: properly label disks for qemu block-commit
	I finally have all the pieces in place to perform a block-commit with
	SELinux enforcing.  There's still missing cleanup work when the commit
	completes, but doing that requires tracking both the backing chain and
	the base and top files within that chain in domain XML across libvirtd
	restarts.  Furthermore, from a security standpoint, once you have
	granted access, you must assume any damage that can be done will be
	done; later revoking access is nice to minimize the window of damage,
	but less important as it does not affect the fact that damage can be
	done in the first place.  Therefore, deferring the revoke efforts until
	we have better XML tracking of what chain operations are in effect,
	including across a libvirtd restart, is reasonable.

	* src/qemu/qemu_driver.c (qemuDomainBlockCommit): Label disks as

2012-10-20  Eric Blake  <eblake@redhat.com>

	blockjob: refactor qemu disk chain permission grants
	Previously, snapshot code did its own permission granting (lock
	manager, cgroup device controller, and security manager labeling)
	inline.  But now that we are adding block-commit and block-copy
	which also have to change permissions, it's better to reuse
	common code for the task.  While snapshot should fall back to
	no access if read-write access failed, block-commit will want to
	fall back to read-only access.  The common code doesn't know
	whether failure to grant read-write access should revert to no
	access (snapshot, block-copy) or read-only access (block-commit).
	This code can also be used to revoke access to unused files after
	block-pull.

	It might be nice to clean things up in a future patch by adding
	new functions to the lock manager, cgroup manager, and security
	manager that takes a single file name and applies context of a
	disk to that file, rather than the current semantics of applying
	context to the entire chain already associated to a disk.  That
	way, we could avoid the games this patch plays of temporarily
	swapping out the disk->src and related fields of the disk.  But
	that would involve more code changes, so this patch really is
	the smallest hack for doing the necessary work; besides, this
	patch is more or less code motion (the hack was already employed
	by the snapshot creation code, we are just making it reusable).

	blockjob: implement shallow commit flag in qemu
	Now that we can crawl the chain of backing files, we can do
	argument validation and implement the 'shallow' flag.  In
	testing this, I discovered that it can be handy to pass the
	shallow flag and an explicit base, as a means of validating
	that the base is indeed the file we expected.

2012-10-20  Eric Blake  <eblake@redhat.com>

	blockjob: wire up online qemu block-commit
	This is the bare minimum to kick off a block commit.  In particular,
	flags support is missing (shallow requires us to crawl the backing
	chain to determine the file name to pass to the qemu monitor command;
	delete requires us to track what needs to be deleted at the time
	the completion event fires).  Also, we are relying on qemu to do
	error checking (such as validating 'top' and 'base' as being members
	of the backing chain), including the fact that the current qemu code
	does not support committing the active layer (although it is still
	planned to add that before qemu 1.3).  Since the active layer won't
	change, we have it easy and do not have to alter the domain XML.
	Additionally, this will fail if SELinux is enforcing, because we fail
	to grant qemu proper read/write access to the files it will modify.

	storage: cache backing chain while qemu domain is live
	Technically, we should not be re-probing any file that qemu might
	be currently writing to.  As such, we should cache the backing
	file chain prior to starting qemu.  This patch adds the cache,
	but does not use it until the next patch.

	Ultimately, we want to also store the chain in domain XML, so that
	it is remembered across libvirtd restarts, and so that the only
	kosher way to modify the backing chain of an offline domain will be
	through libvirt API calls, but we aren't there yet.  So for now, we
	merely invalidate the cache any time we do a live operation that
	alters the chain (block-pull, block-commit, external disk snapshot),
	as well as tear down the cache when the domain is not running.

	storage: remember relative names in backing chain
	In order to search for a backing file name as literally present

	At one point, the code passed through arbitrary strings for file

	not set to NULL but kept instead. And the next duo of calls 'virsh

	does the same as 'virsh destroy'; it sees that newDef is nonNULL so it

	Introduce an internal API for handling file based lockspaces
	The previously introduced virFile{Lock,Unlock} APIs provide a
	way to acquire/release fcntl() locks on individual files. For
	unknown reason though, the POSIX spec says that fcntl() locks
	are released when *any* file handle referring to the same path
	is closed. In the following sequence

	  threadA: fd1 = open("foo")
	  threadB: fd2 = open("foo")
	  threadA: virFileLock(fd1)
	  threadB: virFileLock(fd2)
	  threadB: close(fd2)

	you'd expect threadA to come out holding a lock on 'foo', and
	indeed it does hold a lock for a very short time. Unfortunately
	when threadB does close(fd2) this releases the lock associated
	with fd1. For the current libvirt use case for virFileLock -
	pidfiles - this doesn't matter since the lock is acquired
	at startup while single threaded an never released until
	exit.

	To provide a more generally useful API though, it is necessary
	to introduce a slightly higher level abstraction, which is to
	be referred to as a "lockspace".  This is to be provided by
	a virLockSpacePtr object in src/util/virlockspace.{c,h}. The
	core idea is that the lockspace keeps track of what files are
	already open+locked. This means that when a 2nd thread comes
	along and tries to acquire a lock, it doesn't end up opening
	and closing a new FD. The lockspace just checks the current
	list of held locks and immediately returns VIR_ERR_RESOURCE_BUSY.

	NB, the API as it stands is designed on the basis that the
	files being locked are not being otherwise opened and used
	by the application code. One approach to using this API is to
	acquire locks based on a hash of the filepath.

	eg to lock /var/lib/libvirt/images/foo.img the application
	might do

	   virLockSpacePtr lockspace = virLockSpaceNew("/var/lib/libvirt/imagelocks");
	   lockname = md5sum("/var/lib/libvirt/images/foo.img");
	   virLockSpaceAcquireLock(lockspace, lockname);

	NB, in this example, the caller should ensure that the path
	is canonicalized before calculating the checksum.

	It is also possible to do locks directly on resources by
	using a NULL lockspace directory and then using the file
	path as the lock name eg

	   virLockSpacePtr lockspace = virLockSpaceNew(NULL);
	   virLockSpaceAcquireLock(lockspace, "/var/lib/libvirt/images/foo.img");

	This is only safe to do though if no other part of the process
	will be opening the files. This will be the case when this
	code is used inside the soon-to-be-reposted virlockd daemon

	qemu: reorganize qemuDomainChangeNet and qemuDomainChangeNetBridge
	This patch resolves:

	  https://bugzilla.redhat.com/show_bug.cgi?id=805071

	to the extent that it can be resolved with current qemu functionality.
	It attempts to detect as many situations as possible when the simple
	operation of disconnecting an existing tap device from one bridge and
	attaching it to another will satisfy the change requested in
	virDomainUpdateDeviceFlags() for a network device. Before this patch,
	that situation could only be detected if the pre-change interface
	*and* the post-change interface definition were both "type='bridge'".
	After this patch, it can also be detected if the before or after
	interfaces are any combination of type='bridge' and type='network'
	(the networks can be <forward mode='nat|route|bridge'>, as long as
	they use a Linux host bridge and not macvtap connections).

	This extra effort is especially useful since the recent discovery that
	a netdev_del+netdev_add combo (to reconnect the network device with
	completely different hostside configuration) doesn't work properly
	with current qemu (1.2) unless it is accompanied by the matching
	device_del+device_add - see this mailing list message for details:

	  http://lists.nongnu.org/archive/html/qemu-devel/2012-10/msg02355.html

	(A slight modification of the patch referenced there has been prepared
	to apply on top of this patch, but won't be pushed until qemu can be
	made to work with it.)

	* qemuDomainChangeNet needs access to the virDomainDeviceDef that
	holds the new netdef (so that it can clear out the virDomainDeviceDef
	if it ends up using the NetDef to replace the original), so the
	virDomainNetDefPtr arg is replaced with a virDomainDeviceDefPtr.

	* qemuDomainChangeNet previously checked for *some* changes to the
	interface config, but this check was by no means complete. It was also
	a bit disorganized.

	This refactoring of the code is (I believe) complete in its check of
	all NetDef attributes that might be changed, and either returns a
	failure (for changes that are simply impossible), or sets one of three
	flags:

	  needLinkStateChange - if the device link state needs to go up/down
	  needBridgeChange    - if everything else is the same, but it needs
	                        to be connected to a difference linux host
	                        bridge
	  needReconnect       - if the entire host side of the device needs
	                        to be torn down and reconstructed (currently
	                        non-working, as mentioned above)

	Note that this function will refuse to make any change that requires
	the *guest* side of the device to be detached (e.g. changing the PCI
	address or mac address). Those would be disruptive enough to the guest
	that it's reasonable to require an explicit detach/attach sequence
	from the management application.

	* As mentioned above, qemuDomainChangeNet also does its best to
	understand when a simple change in attached bridge for the existing
	tap device will work vs. the need to completely tear down/reconstruct
	the host side of the device (including tap device).

	This patch *does not* implement the "reconnect" code anyway - there is
	a placeholder that turns that into an error. Rather, the purpose of
	this patch is to replicate existing behavior with code that is ready
	to have that functionality plugged in in a later patch.

	* The expanded uses for qemuDomainChangeNetBridge meant that it needed
	to be enhanced as well - it no longer replaces the original brname
	string in olddev with the new brname; instead, it relies on the
	caller to replace the *entire* olddev with newdev (since we've gone
	to great lengths to assure they are functionally identical other
	than the name of the bridge, this is now not only safe, but more
	correct). Additionally, qemuDomainNetChangeBridge can now set the
	bridge for type='network' interfaces as well as plain type='bridge'
	interfaces. (Note that I had to make this change simultaneous to the
	reorganization of qemuDomainChangeNet because the two are too
	closely intertwined to separate).

	conf: Initialize the pinning policy for vcpus

	Since 0.4.4, this element can contain an optional cpuset attribute,
	which is a comma-separated list of physical CPU numbers that virtual
	CPUs can be pinned to.

	However, it's not the truth, libvirt actually pins the domain
	process to the specified pCPUs by "cpuset" of <vcpu>. And the
	vcpu thread are pinned to all available pCPUs if no <vcpupin>
	is specified for it.

	This patch is to implement the codes to inherit <vcpu>'s "cpuset" for
	vcpu that doesn't have <vcpupin> specified, and <vcpupin>
	for these vcpu will be ignored when formating. Underlying

	conf: Ignore vcpupin for not onlined vcpus when parsing
	Setting pinning policy for vcpu which exceeds current vcpus number
	just makes no sense, however, it could cause various problems, E.g.

	<vcpu current='1'>4</vcpu>
	<cputune>
	  <vcpupin vcpuid='3' cpuset='4'/>
	</cputune>

	% virsh start linux
	error: Failed to start domain linux
	error: cannot set CPU affinity on process 32534: No such process

	We must have some odd codes underlying which produces the
	"on process 32534", but the point is why we not to prevent
	earlier when parsing? Note that this is only one of the
	problem it could cause.

	This patch is to ignore the <vcpupin> for not onlined vcpus.

2012-10-15  Osier Yang  <jyang@redhat.com>

	doc: Sort out the relationship between <vcpu>, <vcpupin>, and <emulatorpin>
	These 3 elements conflicts with each other in either the doc
	or the underlying codes.

	Current problems:

	Problem 1:

	The doc shouldn't simply say "These settings are superseded
	by CPU tuning. " for element <vcpu>. As except the tuning, <vcpu>
	allows to specify the current, maxmum vcpu number. Apart from that,
	<vcpu> also allows to specify the placement as "auto", which binds
	the domain process to the advisory nodeset from numad.

	Problem 2:

	Doc for <vcpu> says its "cpuset" specify the physical CPUs
	that the vcpus can be pinned. But it's not the truth, as
	actually it only pin domain process to the specified physical
	CPUs. So either it's a document bug, or code bug.

	Problem 3:

	Doc for <vcpupin> says it supersed "cpuset" of <vcpu>, it's
	not quite correct, as each <vcpupin> specify the pinning policy
	only for one vcpu. How about the ones which doesn't have
	<vcpupin> specified? it says the vcpu will be pinned to all
	available physical CPUs, but what's the meaning of attribute
	"cpuset" of <vcpu> then?

	Problem 4:

	Doc for <emulatorpin> says it pin the emulator threads (domain
	process in other context, perhaps another follow up patch to
	cleanup the inconsistency is needed) to the physical CPUs
	specified its attribute "cpuset". Which conflicts with
	<vcpu>'s "cpuset". And actually in the underlying codes,
	it set the affinity for domain process twice if both
	"cpuset" for <vcpu> and <emulatorpin> are specified,
	and <emulatorpin>'s pinning will override <vcpu>'s.

	Problem 5:

	When "placement" of <vcpu> is "auto" (I.e. uses numad to
	get the advisory nodeset to which the domain process is
	pinned to), it will also be overridden by <emulatorpin>,

	This patch is trying to sort out the conflicts or bugs by:

	1) Don't say <vcpu> is superseded by <cputune>

	2) Keep the semanteme for "cpuset" of <vcpu> (I.e. Still says it
	   specify the physical CPUs the virtual CPUs). But modifying it
	   to mention it also set the pinning policy for domain process,
	   and the CPU placement of domain process specified by "cpuset"
	   of <vcpu> will be ingored if <emulatorpin> specified, and
	   similary, the CPU placement of vcpu thread will be ignored
	   if it has <vcpupin> specified, for vcpu which doesn't have
	   <vcpupin> specified, it inherits "cpuset" of <vcpu>.

	3) Don't say <vcpu> is supersed by <vcpupin>. If neither <vcpupin>
	   nor "cpuset" of <vcpu> is specified, the vcpu will be pinned
	   to all available pCPUs.

	4) If neither <emulatorpin> nor "cpuset" of <vcpu> is specified,
	   the domain process (emulator threads in the context) will be
	   pinned to all available pCPUs.

	5) If "placement" of <vcpu> is "auto", <emulatorpin> is not allowed.

	6) hotplugged vcpus will also inherit "cpuset" of <vcpu>

	Codes changes according to above document changes:

	1) Inherit def->cpumask for each vcpu which doesn't have <vcpupin>
	   specified, during parsing.

	2) ping the vcpu which doesn't have <vcpupin> specified to def->cpumask
	   either by cgroup for sched_setaffinity(2), which is actually done
	   by 1).

	3) Error out if "placement" == "auto", and <emulatorpin> is specified.
	   Otherwise, <emulatorpin> is honored, and "cpuset" of <cpuset> is
	   ignored.

	4) Setup cgroup for each hotplugged vcpu, and setup the pinning policy
	   by either cgroup or sched_setaffinity(2).

	5) Remove cgroup and <vcpupin> for each hot unplugged vcpu.

	Patches are following (6 in total except this patch)

	selinux: Use raw contexts
	We are currently able to work only with non-translated SELinux
	contexts, but we are using functions that work with translated
	contexts throughout the code.  This patch swaps all SELinux context
	translation relative calls with their raw sisters to avoid parsing
	problems.

	The problems can be experienced with mcstrans for example.  The
	difference is that if you have translations enabled (yum install
	mcstrans; service mcstrans start), fgetfilecon_raw() will get you
	something like 'system_u:object_r:virt_image_t:s0', whereas
	fgetfilecon() will return 'system_u:object_r:virt_image_t:SystemLow'
	that we cannot parse.

	I was trying to confirm that the _raw variants were here since the dawn of
	time, but the only thing I see now is that it was imported together in
	the upstream repo [1] from svn, so before 2008.

	Thanks Laurent Bigonville for finding this out.

	qemu: Make save/restore with USB devices usable
	Save/restore with passed through USB devices currently only works if the
	USB device can be found at the same USB address where it used to be
	before saving a domain. This makes sense in case a user explicitly
	configure the USB address in domain XML. However, if the device was
	found automatically by vendor/product identification, we should try to
	search for that device when restoring the domain and use any device we
	find as long as there is only one available. In other words, the USB
	device can now be removed and plugged again or the host can be rebooted
	between saving and restoring the domain.

	locking: Implement lock failure action in sanlock driver
	While the changes to sanlock driver should be stable, the actual
	implementation of sanlock_helper is supposed to be replaced in the
	future. However, before we can implement a better sanlock_helper, we
	need an administrative interface to libvirtd so that the helper can just
	pass a "leases lost" event to the particular libvirt driver and
	everything else will be taken care of internally. This approach will
	also allow libvirt to pass such event to applications and use
	appropriate reasons when changing domain states.

	The temporary implementation handles all actions directly by calling
	appropriate libvirt APIs (which among other things means that it needs
	to know the credentials required to connect to libvirtd).

	esx: Disable libcurl's use of signals to fix a segfault
	libcurl uses a SIGALRM in combination with sigsetjmp/siglongjmp to be
	able to abort a DNS lookup when it takes too long. The problem with this
	in a multi-threaded application is that the signal handler for SIGALRM
	and the call to siglongjmp can be executed on a thread that is different
	from the one that initially did the SIGALRM setup and the call to
	sigsetjmp. In the reported case this triggered a segfault.

	Disable libcurl's use of signals to avoid this situation. This has the
	disadvantage of losing the ability to abort synchronous DNS lookups which
	might result in libcurl getting stuck in a DNS lookup in the worst case.
	When libcurl was build with an asynchronous DNS backend such as c-ares
	then there is no problem because the timeout mechanism works without
	signals here anyway.

	CFLAGS=-g failed due to a gcc 4.2.1 limitation.

	* .gnulib: Update to latest, for gcc 4.2 support and fixed FreeBSD tests.

	doc: update description about security labels on formatdomain.html
	This patch adds a brief description about labels for each security
	driver.

2012-10-03  Marcelo Cerri  <mhcerri@linux.vnet.ibm.com>

	security: also parse user/group names instead of just IDs for DAC labels
	The DAC driver is missing parsing of group and user names for DAC labels
	and currently just parses uid and gid. This patch extends it to support
	names, so the following security label definition is now valid:

	  <seclabel type='static' model='dac' relabel='yes'>
	      <label>qemu:qemu</label>
	      <imagelabel>qemu:qemu</imagelabel>
	  </seclabel>

	When it tries to parse an owner or a group, it first tries to resolve it as
	a name, if it fails or it's an invalid user/group name then it tries to
	parse it as an UID or GID. A leading '+' can also be used for both owner and
	group to force it to be parsed as IDs, so the following example is also
	valid:

	  <seclabel type='static' model='dac' relabel='yes'>
	      <label>+101:+101</label>
	      <imagelabel>+101:+101</imagelabel>
	  </seclabel>

	This ensures that UID 101 and GUI 101 will be used instead of an user or
	group named "101".

	build: avoid -Wno-format on new-enough gcc
	Commit c579d6b added a sledgehammer to silence spurious warnings from
	gcc 4.2, but in the process, it also silenced useful warnings from
	gcc 4.3 through 4.5.  As a result, a bug slipped in to commit 0caccb58.

	Tested with FreeBSD (gcc 4.2.1), RHEL 6.3 (gcc 4.4), and F17 (gcc 4.7.2),
	where the former didn't trip on spurious warnings, and where the latter
	two detected a revert of 2b804cf.

	* m4/virt-compile-warnings.m4 (-Wno-format): Probe for the actual
	spurious message, to once again allow gcc 4.4 to use -Wformat.

	qemu: Kill processes used for QMP caps probing
	Since libvirt switched to QMP capabilities probing recently, it starts
	QEMU process used for this probing with -daemonize, which means
	virCommandAbort can no longer reach these processes. As a result of
	that, restarting libvirtd will leave several new QEMU processes behind.
	Let's use QEMU's -pidfile and use it to kill the process when QMP caps
	probing is done.

	qemu: Use proper agent entering function when freezing filesystems
	When doing snapshots, the filesystem freeze function used the agent
	entering function that expects the qemud_driver unlocked. This might

	The only call path of this function has the qemud_driver locked, so this

	build: avoid journald on rhel 5
	Commit f6430390 broke builds on RHEL 5, where glibc (2.5) is too
	old to support mkostemp (2.7) or htole64 (2.9).  While gnulib
	has mkostemp, it still lacks htole64; and it's not worth dragging
	in replacements on systems where journald is unlikely to exist
	in the first place, so we just use an extra configure-time check
	as our witness of whether to attempt compiling the code.

	* src/util/logging.c (virLogParseOutputs): Don't attempt to
	compile journald on older glibc.
	* configure.ac (AC_CHECK_DECLS): Check for htole64.

	build: avoid infinite autogen loop
	Several people have reported that if the .gnulib submodule is dirty,
	then 'make' will go into an infinite loop attempting to rerun bootstrap,
	because that never cleans up the dirty submodule.  By default, we
	should halt and make the user investigate, but if the user doesn't
	know why or care that the submodule is dirty, I also added the ability
	to 'make CLEAN_SUBMODULE=1' to get things going again.

	Also, while testing this, I noticed that when a submodule update was
	needed, 'make' would first run autoreconf, then bootstrap (which
	reruns autoreconf); adding a strategic dependency allows for less work.

	* .gnulib: Update to latest, for maint.mk improvements.
	* cfg.mk (_autogen): Also hook maint.mk, to run before autoreconf.
	* autogen.sh (bootstrap): Refuse to run if gnulib is dirty, unless
	user requests discarding gnulib changes.

	If virGetDomain fails it already reports an error, don't overwrite it

	build: default selinuxfs mount point to /sys/fs/selinux
	Currently if you build on a machine that does not support SELinux we end up
	with the default mount point being /selinux, since this is moved to

	Add support for detecting capablities using QMP commands
	Start a QEMU process using

	   $QEMU -S -no-user-config -nodefaults \
	         -nographic -M none -qmp unix:/some/path,server,nowait

	and talk QMP over stdio to discover what capabilities the
	binary supports. This works for QEMU 1.2.0 or later and
	for older QEMU automatically fallback to the old approach
	of parsing -help and related command line args.

	Ignore error from query-cpu-definitions
	Some architectures provide the query-cpu-definitions command,
	but are set to always return a "GenericError" from it :-(
	Catch this & treat it as if there was an empty list of CPUs
	returned

	Avoid bogus I/O event errors when closing the QEMU monitor
	After calling qemuMonitorClose(), it is still possible for
	the QEMU monitor I/O event callback to get invoked. This
	will trigger an error message because mon->fd has been set
	to -1 at this point. Silently ignore the case where mon->fd
	is -1, likewise for mon->watch being zero.

	Remove need to pass in a virDomainObjPtr instance to qemuMonitorOpen
	The qemuMonitorOpen method only needs a virDomainObjPtr in order
	to access the QEMU pid. This is not critical when detecting the
	QEMU capabilties, so can easily be skipped

	Fix QEMU test with 1.2.0 help output
	The help output for QEMU 1.2.0 changed 'pci-assign' to 'kvm-pci-assign'.
	Since the new capabilities code does exact device name matching
	instead of substring matching, this caused the capabilities to go
	missing.

	Automatically enable systemd journal logging
	Probe to see if the systemd journal is accessible, and if
	so enable logging to the journal by default, rather than
	stderr (current default under systemd).

2012-09-28  Daniel P. Berrange  <berrange@redhat.com>

	Add systemd journal support
	Add support for logging to the systemd journal, using its
	simple client library. The benefit over syslog is that it
	accepts structured log data, so the journald can store
	individual items like code file/line/func separately from
	the string message. Tools which require structured log
	data can then query the journal to extract exactly what
	they desire without resorting to string parsing

	While systemd provides a simple client library for logging,
	it is more convenient for libvirt to directly write its
	own client code. This lets us build up the iovec's on
	the stack, avoiding the need to alloc memory when writing
	log messages.

2012-09-28  Daniel P. Berrange  <berrange@redhat.com>

	Refactor qemuCapsParseDeviceStr to work from data tables
	Currently the qemuCapsParseDeviceStr method has a bunch of open
	coded string searches/comparisons to detect devices and their
	properties. Soon this data will be obtained from QMP queries
	instead of -device help output. Maintaining the list of device
	and properties in two places is undesirable. Thus the existing
	qemuCapsParseDeviceStr() method needs to be refactored to
	separate the device types and properties from the actual
	search code.

	Thus the -device help output is now parsed to construct a
	list of device names, and device properties. These are then
	checked against a set of datatables to set the capability
	flags

	Include filename explicitly in logging APIs
	Currently the logging APIs have a 'const char *category' parameter
	which indicates where the log message comes from. This is typically
	a combination of the __FILE__ string and other prefix. Split the
	__FILE__ off into a dedicated parameter so it can passed to the
	log outputs

	network: fix dnsmasq/radvd binding to IPv6 on recent kernels
	I hit this problem recently when trying to create a bridge with an IPv6
	address on a 3.2 kernel: dnsmasq (and, further, radvd) would not bind to
	the given address, waiting 20s and then giving up with -EADDRNOTAVAIL
	(resp. exiting immediately with "error parsing or activating the config
	file", without libvirt noticing it, BTW). This can be reproduced with (I
	think) any kernel >= 2.6.39 and the following XML (to be used with
	"virsh net-create"):

	        <network>
	          <name>test-bridge</name>
	          <bridge name='testbr0' />
	          <ip family='ipv6' address='fd00::1' prefix='64'>
	          </ip>
	        </network>

	(it happens even when you have an IPv4, too)

	The problem is that since commit [1] (which, ironically, was made to
	“help IPv6 autoconfiguration”) the linux bridge code makes bridges
	behave like “real” devices regarding carrier detection. This makes the
	bridges created by libvirt, which are started without any up devices,
	stay with the NO-CARRIER flag set, and thus prevents DAD (Duplicate
	address detection) from happening, thus letting the IPv6 address flagged
	as “tentative”. Such addresses cannot be bound to (see RFC 2462), so
	dnsmasq fails binding to it (for radvd, it detects that "interface XXX
	is not RUNNING", thus that "interface XXX does not exist, ignoring the
	interface" (sic)). It seems that this behavior was enhanced somehow with
	commit [2] by avoiding setting NO-CARRIER on empty bridges, but I
	couldn't reproduce this behavior on my kernel. Anyway, with the “dummy
	tap to set MAC address” trick, this wouldn't work.

	To fix this, the idea is to get the bridge's attached device to be up so
	that DAD can happen (deactivating DAD altogether is not a good idea, I
	think). Currently, libvirt creates a dummy TAP device to set the MAC
	address of the bridge, keeping it down. But even if we set this device
	up, it is not RUNNING as soon as the tap file descriptor attached to it
	is closed, thus still preventing DAD. So, we must modify the API a bit,
	so that we can get the fd, keep the tap device persistent, run the
	daemons, and close it after DAD has taken place. After that, the bridge
	will be flagged NO-CARRIER again, but the daemons will be running, even
	if not happy about the device's state (but we don't really care about
	the bridge's daemons doing anything when no up interface is connected to
	it).

	Other solutions that I envisioned were:
	      * Keeping the *-nic interface up: this would waste an fd for each
	        bridge during all its life. May be acceptable, I don't really
	        know.
	      * Stop using the dummy tap trick, and set the MAC address directly
	        on the bridge: it is possible since quite some time it seems,
	        even if then there is the problem of the bridge not being
	        RUNNING when empty, contrary to what [2] says, so this will need
	        fixing (and this fix only happened in 3.1, so it wouldn't work
	        for 2.6.39)
	      * Using the --interface option of dnsmasq, but I saw somewhere
	        that it's not used by libvirt for backward compatibility. I am
	        not sure this would solve this problem, though, as I don't know
	        how dnsmasq binds itself to it with this option.

	This is why this patch does what's described earlier.

	This patch also makes radvd start even if the interface is
	“missing” (i.e. it is not RUNNING), as it daemonizes before binding to
	it, and thus sometimes does it after the interface has been brought down
	by us (by closing the tap fd), and then originally stops. This also
	makes it stop yelling about it in the logs when the interface is down at
	a later time.

	Remove probing of CPU models when launching QEMU guests
	When launching a QEMU guest the binary is probed to discover
	the list of supported CPU names. Remove this probing with a
	simple lookup of CPU models in the qemuCapsPtr object. This
	avoids another invocation of the QEMU binary during the
	startup path.

	As a nice benefit we can now remove all the nasty hacks from
	the test suite which were done to avoid having to exec QEMU
	on the test system. The building of the -cpu command line
	can just rely on data we pre-populate in qemuCapsPtr.

2012-09-27  Daniel P. Berrange  <berrange@redhat.com>

	Remove probing of machine types when canonicalizing XML
	When XML for a new guest is received, the machine type is
	immediately canonicalized into the version specific name.
	This involves probing QEMU for supported machine types.
	Replace this probing with a lookup of the machine types
	in the (hopefully cached) qemuCapsPtr object

	Remove probing of flags when launching QEMU guests
	Remove all use of the existing APIs for querying QEMU
	capability flags. Instead obtain a qemuCapsPtr object
	from the global cache. This avoids the execution of
	'qemu -help' (and related commands) when launching new
	guests.

	Switch over to use cache for building QEMU capabilities
	When building up a virCapsPtr instance, the QEMU driver
	was copying the list of machine types across from the
	previous virCapsPtr instance, if the QEMU binary had not
	changed. Replace this ad-hoc caching of data with use
	of the new qemuCapsCache global cache.

	Add a qemu capabilities cache manager
	Introduce a qemuCapsCachePtr object to provide a global cache
	of capabilities for QEMU binaries. The cache auto-populates
	on first request for capabilities about a binary, and will
	auto-refresh if the binary has changed since a previous cache
	was populated

	At frame #10 we are holding the domain lock, we call into
	qemuProcessStop() to cleanup QEMU, which triggers the monitor
	to close, which invokes qemuProcessHandleMonitorDestroy() which
	tries to obtain the domain lock again. This is a non-recursive
	lock, hence hang.

	Since qemuMonitorPtr is a virObject, the unref call in
	qemuProcessHandleMonitorDestroy no longer needs mutex
	protection. The assignment of priv->mon = NULL, can be
	instead done by the caller of qemuMonitorClose(), thus
	removing all need for locking.

	Don't skip over socket label cleanup
	If QEMU quits immediately after we opened the monitor it was
	possible we would skip the clearing of the SELinux process
	socket context

	Move most of qemuProcessKill into virProcessKillPainfully
	In the cgroups APIs we have a virCgroupKillPainfully function
	which does the loop sending SIGTERM, then SIGKILL and waiting
	for the process to exit. There is similar functionality for
	simple processes in qemuProcessKill, but it is tangled with
	the QEMU code. Untangle it to provide a virProcessKillPainfuly
	function

	Don't ignore return value of qemuProcessKill
	When calling qemuProcessKill from the virDomainDestroy impl
	in QEMU, do not ignore the return value. This ensures that
	if QEMU fails to respond to SIGKILL, the caller will know
	about the failure.

	network: backend for virNetworkUpdate of interface list
	<interface> elements are location inside the <forward> element of a
	network. There is only one <forward> element in any network, but it
	might have many <interface> elements. This element only contains a
	single attribute, "dev", which is the name of a network device
	(e.g. "eth0").

	Since there is only a single attribute, the modify operation isn't
	supported for this "section", only add-first, add-last, and
	delete. Also, note that it's not permitted to delete an interface from
	the list while any guest is using it. We may later decide this is safe
	(because removing it from the list really only excludes it from
	consideration in future guest allocations of interfaces, but doesn't
	affect any guests currently connected), but for now this limitation
	seems prudent (of course when changing the persistent config, this
	limitation doesn't apply, because the persistent config doesn't
	support the concept of "in used").

	Another limitation - it is also possible for the interfraces in this
	list to be described by PCI address rather than netdev name. However,
	I noticed while writing this function that we currently don't support
	defining interfaces that way in config - the only method of getting
	interfaces specified as <adress type='pci' ..../> instead of
	<interface dev='xx'/> is to provide a <pf dev='yy'/> element under
	forward, and let the entries in the interface list be automatically
	populated with the virtual functions (VF) of the physical function
	device given in <pg>.

	As with the other virNetworkUpdate section backends, support for this
	section is completely contained within a single static function, no
	other changes were required, and only functions already called from
	elsewhere within the same file are used in the new content for this
	existing function (i.e., adding this code should not cause a new build
	problem on any platform).

	qemu: wait for SPICE to migrate
	Recently, there have been some improvements made to qemu so it
	supports seamless migration or something very close to it.
	However, it requires libvirt interaction. Once qemu is migrated,
	the SPICE server needs to send its internal state to the destination.
	Once it's done, it fires SPICE_MIGRATE_COMPLETED event and this
	fact is advertised in 'query-spice' output as well.
	We must not kill qemu until SPICE server finishes the transfer.

	Don't use O_TRUNC when opening QEMU logfiles
	SELinux wants all log files opened with O_APPEND. When
	running non-root though, libvirtd likes to use O_TRUNC
	to avoid log files growing in size indefinitely. Instead
	of using O_TRUNC though, we can use O_APPEND and then

	build: fix detection of netcf linked with libnl1
	Commit 9298bfbcb introduced code to detect if netcf is linked with
	libnl1, and to prefer libnl1 over libnl3 when this is the case.
	This behaviour can be disabled by setting LIBNL_CFLAGS to any value,
	including the empty string.
	However, configure.ac sets LIBNL_CFLAGS to "" before attempting
	libnl detection, so the libnl1 detection code is always disabled.
	This caused issues on my f17 system where netcf is linked with libnl1
	but libvirt got built with libnl3.

	This commit removes the setting of the LIBNL_* variables to "" as
	this does not appear to be needed. After this change, libnl1 is
	used when building libvirt on my f17 system.

	network: log error for unknown virNetworkUpdate command codes
	Every level of the code for virNetworkUpdate was assuming that some
	other level was checking for validity of the "command" arg, but none
	actually were. The result was that an invalid command code would do
	nothing, but also report success.

	Since the command code isn't used until the very lowest level backend
	functions, that's where I put the check. I made a separate one-line
	function to log the error. The compiler would have combined the
	identical strings used by multiple calls if I'd just called
	virReportError directly in each location, but sending them all to the
	same string in the source guards against inadvertant divergence (which
	would lead to extra work for translators.)

2012-09-22  Laine Stump  <laine@laine.org>

	network: make virNetworkObjUpdate error detection/recovery better
	1) virNetworkObjUpdate should be an all or none operation, but in the
	case that we want to update both the live state and persistent config
	versions of the network, it was committing the update to the live
	state before starting to update the persistent config. If update of
	the persistent config failed, we would leave with things in an
	inconsistent state - the live state would be updated (even though an
	error was returned), but persistent config unchanged.

	This patch changed virNetworkObjUpdate to use a separate pointer for
	each copy of the virNetworkDef, and not commit either of them in the
	virNetworkObj until both live and config parts of the update have
	successfully completed.

	2) The parsers for various pieces of the virNetworkDef have all sorts
	of subtle limitations on them that may not be known by the
	Update[section] function, making it possible for one of these
	functions to make a modification directly to the object that may not
	pass the scrutiny of a subsequent parse. But normally another parse
	wouldn't be done on the data until the *next* time the object was
	updated (which could leave the network definition in an unusable
	state).

	Rather than fighting the losing battle of trying to duplicate all the
	checks from the parsers into the update functions as well, the more
	foolproof solution to this is to simply do an extra
	virNetworkDefCopy() operation on the updated networkdef -
	virNetworkDefCopy() does a virNetworkFormat() followed by a
	virNetworkParseString(), so it will do all the checks we need. If this
	fails, then we don't commit the changed def.

	network: don't "refresh" iptables rules on rule-less networks
	The bridge driver implementation of virNetworkUpdate() removes and
	re-adds iptables rules any time a network has an <ip>, <forward>, or
	<forward>/<interface> element updated. There are some types of
	networks that have those elements and yet have no iptables rules
	associated with them, and unfortunately the functions that remove/add
	iptables rules don't check the type of network before attempting to
	remove/add the rules, sometimes leading to an erroneous failure of the
	entire update operation.

	Under normal circumstances I would refactor the lower level functions
	to be more robust, but to avoid code churn as much as possible, I've
	just added extra checks directly to networkUpdate().

	network: backend for virNetworkUpdate of portgroups
	portgroup elements are located in the toplevel of <network>
	objects. There can be multiple <portgroup> elements, and they each
	have a unique name attribute.

	Add, delete, and modify are all supported for portgroup. When deleting
	a portgroup, only the name must be specified in the provided xml - all
	other attributes and subelements are ignored for the purposes of
	matching and existing portgroup.

	The bridge driver and virsh already know about the portgroup element,
	so providing this backend should cause the entire stack to work. Note
	that in the case of portgroup, there is no external daemon based on
	the portgroup config, so nothing must be restarted.

	It is important to note that guests make a copy of the appropriate
	network's portgroup data when they are started, so although an updated
	portgroup's configuration will have an affect on new guests started
	after the cahange, existing guests won't magically have their
	bandwidth changed, for example. If something like that is desired, it
	will take a lot of redesign work in the way network devices are setup
	(there is currently no link from the network back to the individual
	interfaces using it, much less from a portgroup within a network back
	to the individual interfaces).

	network: backend for virNetworkUpdate of dhcp range
	The dhcp range element is contained in the <dhcp> element of one of a
	network's <ip> elements. There can be multiple <range>
	elements. Because there are only two attributes (start and end), and
	those are exactly what you would use to identify a particular range,
	it doesn't really make sense to modify an existing element, so
	VIR_NETWORK_UPDATE_COMMAND_MODIFY isn't supported for this section,
	only ADD_FIRST, ADD_LAST, and DELETE.

	Since virsh already has support for understanding all the defined
	sections, this new backend is automatically supported by virsh. You
	would use it like this:

	  virsh net-update mynet add ip-dhcp-range \
	        "<range start='1.2.3.4' end='1.2.3.20'/>" --live --config

	The bridge driver also already supports all sections, so it's doing
	the correct thing in this case as well - since the dhcp range is
	placed on the dnsmasq commandline, the bridge driver recreates the
	dnsmasq commandline, and re-runs dnsmasq whenever a range is
	added/deleted (and AFFECT_LIVE is specified in the flags).

2012-09-21  Laine Stump  <laine@laine.org>

	virsh: new net-update command
	This command uses the new virNetworkUpdate() API to modify an existing
	network definition, and optionally have those modifications take
	effect immediately without restarting the network.

	An example usage:

	  virsh net-update mynet add-last ip-dhcp-host \
	   "<host mac='00:11:22:33:44:55' ip='192.168.122.45'/>" \
	   --live --config

	If you like, you can instead put the xml into a file, and call like
	this:

	  virsh net-update mynet add ip-dhcp-host /tmp/myxml.xml
	   --live --config

	virsh will autodetect whether the argument is itself an xml element,
	or if it's a file, by looking at the first character - the first
	character of an xml element is always "<", and the first character of
	a file is almost always *not* "<" (in the rare case that it is, the
	user could specify "./<filename...").

	A --parent-index option is also available (to give the index within a
	list of parent objects, e.g. the index of the parent <ip> element when
	updating ip-dhcp-host elements), but is optional and at least for now
	will probably be used rarely.

	--live, --config, and --current options - if you specify --live, only
	the live state of the network will be updated. If you also specify
	--config, then the persistent configuration will also be updated;
	these two commands can be given separately, or both together. If you
	don't specify either (you can optionally specify "--current" for the
	same effect), then the "current" config will be updated (i.e. if the
	network is active, then only its live config is affected, but if the
	network is inactive, only the persistent config is affected).

	tests: Add tests for dump-core option

2012-09-20  Martin Kletzander  <mkletzan@redhat.com>

	qemu: add support for dump-guest-core option
	The "dump-guest-core' option is new option for the machine type
	(-machine pc,dump-guest-core) that controls whether the guest memory
	will be marked as dumpable.

	While testing this, I've found out that the value for the '-M' options
	is not parsed correctly when additional parameters are used. However,
	when '-machine' is used for the same options, it gets parsed as
	expected. That's why this patch also modifies the parsing and creating
	of the command line, so both '-M' and '-machine' are recognized. In
	QEMU's help there is only mention of the 'machine parameter now with
	no sign of the older '-M'.

	security: Don't ignore errors when parsing DAC security labels
	The DAC security driver silently ignored errors when parsing the DAC
	label and used default values instead.

	With a domain containing the following label definition:

	<seclabel type='static' model='dac' relabel='yes'>
	  <label>sdfklsdjlfjklsdjkl</label>
	</seclabel>

	the domain would start normaly but the disk images would be still owned
	by root and no error was displayed.

	This patch changes the behavior if the parsing of the label fails (note
	that a not present label is not a failure and in this case the default
	label should be used) the error isn't masked but is raised that causes
	the domain start to fail with a descriptive error message:

	virsh #  start tr
	error: Failed to start domain tr
	error: internal error invalid argument: failed to parse DAC seclabel
	'sdfklsdjlfjklsdjkl' for domain 'tr'

	I also changed the error code to "invalid argument" from "internal
	error" and tweaked the various error messages to contain correct and
	useful information.

	qemu: Cleanup boot parameter building
	This patch cleans up building the "-boot" parameter and while on that
	fixes one inconsistency by modifying these things:

	 - I completed the unfinished virDomainBootMenu enum by specifying
	   LAST, declaring it and also declaring the TypeFromString and
	   TypeToString parameters.
	 - Previously mentioned TypeFromString and TypeToString are used when
	   parsing the XML.
	 - Last, but not least, visible change is that the "-boot" parameter
	   is built and parsed properly:
	    - The "order=" prefix is used only when additional parameters are
	      used (menu, etc.).
	    - It's rewritten in a way that other parameters can be added
	      easily in the future (used in following patch).
	    - The "order=" parameter is properly parsed regardless to where it
	      is placed in the string (e.g. "menu=on,order=nc").
	    - The "menu=" parameter (and others in the future) are created
	      when they should be (i.e. even when bootindex is supported and
	      used, but not when bootloader is selected).

	   clean up" function. No libvirt errors are suppresed by this.

	Add a ./run script for running programs from the local directory.
	With this script you can run libvirt programs without needing to
	install them first.  You just have to do for example:

	  ./run ./tools/virsh [args ...]

	If you are already in the tools/ subdirectory, then the following
	command will also work:

	  ../run ./virsh [...]

	You can also run the C programs under valgrind like this:

	  ./run valgrind [valgrind opts...] ./program

	or under gdb:

	  ./run gdb --args ./program

	This also works with sudo (eg. if you need root access for libvirt):

	  sudo ./run ./tools/virsh list --all

	Derived from libguestfs and simplified.  The ./run script in
	libguestfs is much more sophisticated:

	network: implement backend of virNetworkUpdate(IP_DHCP_HOST)
	This patch fills in the first implementation for one of the
	virNetworkUpdate sections. With this code, you can now add/delete/edit
	<host> entries in a network's <ip> address <dhcp> element (by
	specifying a section of VIR_NETWORK_SECTION_IP_DHCP_HOST).

	If you pass in a parentIndex of -1, the code will automatically find
	the one ip element that has a <dhcp> section and make the updates
	there. Otherwise, you can specify an index >= 0, and libvirt will look
	for that particular instance of <ip> in the network, and modify its
	<dhcp> element. (This currently isn't very useful, because libvirt
	only supports having dhcp information on a single IP address, but that
	could change in the future).

	When adding a new host entry
	(VIR_NETWORK_UPDATE_COMMAND_ADD_(FIRST|LAST)), the existing entries
	will be compared to the new entry, and if any non-empty attribute
	matches, the add will fail. When updating an existing entry
	(VIR_NETWORK_UPDATE_COMMAND_MODIFY), the mac address or name will be
	used to find the existing entry, and other fields will only be updated
	(note there is some potential for ambiguity here if you specify the
	mac address from one entry and the name from another).  When deleting
	an existing entry (VIR_NETWORK_UPDATE_COMMAND_DELETE), all non-empty
	attributes in the supplied xml arg will be compared - all of them must
	match before libvirt will delete the host.

	The xml should be a fully formed <host> element as it would appear in
	a network definition, e.g. "<host mac=00:11:22:33:44:55 ip=10.1.23.22
	name='testbox'/>" (when adding/updating, ip and one of mac|name is
	required; when deleting, you can specify any one, two, or all
	attributes, but they all must match the target element).

	As with the update of any other section, you can choose to affect the
	live config (with flag VIR_NETWORK_UPDATE_AFFECT_LIVE), the persistent
	config (VIR_NETWORK_UPDATE_AFFECT_CONFIG), or both. If you've chosen
	to affect the live config, those changes will take effect immediately,
	with no need to destroy/restart the network.

	An example of adding a host entry:

	   virNetworkUpdate(net, VIR_NETWORK_UPDATE_COMMAND_ADD_LAST,
	                     VIR_NETWORK_SECTION_IP_DHCP_HOST, -1,
	                    "<host mac='00:11:22:33:44:55' ip='192.168.122.5'/>",
	                    VIR_NETWORK_UPDATE_AFFECT_LIVE
	                    | VIR_NETWORK_UPDATE_AFFECT_CONFIG);

	To delete that same entry:

	   virNetworkUpdate(net, VIR_NETWORK_UPDATE_COMMAND_DELETE,
	                    VIR_NETWORK_SECTION_IP_DHCP_HOST, -1,
	                    "<host mac='00:11:22:33:44:55'/>",
	                    VIR_NETWORK_UPDATE_AFFECT_LIVE
	                    | VIR_NETWORK_UPDATE_AFFECT_CONFIG);

	(you could also delete it by replacing "mac='00:11:22:33:44:55'" with
	"ip='192.168.122.5'".)

	network: restart radvd/dnsmasq if needed when libvirtd is restarted
	A user on IRC had accidentally killed all of his libvirt-started
	dnsmasq instances (due to a buggy dnsmasq service script in Fedora
	16), and had hoped that libvirtd would notice this on restart and
	reload all the dnsmasq daemons (as it does with iptables
	rules). Unfortunately this was not the case - as long as the network
	object had a pid registered for dnsmasq and/or radvd, it assumed that
	the processes were running.

	This patch takes advantage of the new utility functions in
	bridge_driver.c to do a "refresh" of all radvd and dnsmasq processes
	started by libvirt each time libvirtd is restarted - this function
	attempts to do a SIGHUP of each existing process, and if that fails,
	it restarts the process, rebuilding all the associated config files
	and commandline parameters in the process. This normally has no
	effect, but will be useful in solving the occasional "odd situation"
	without needing to take the drastic step of destroying/re-starting the
	network.

	network: implement virNetworkUpdate for test_driver
	The test driver does nothing outside of keeping track of each
	network's config/state in the in-memory database maintained by

	network: implement virNetworkUpdate for bridge_driver
	Call the network_conf function that modifies the live/persistent/both
	config, then refresh/restart dnsmasq/radvd if necessary, and finally
	save the config in the proper place(s).

	This patch also needed to uncomment a few utility functions that were
	added inside #if 0 in the previous commit (to avoid compiler errors
	due to unreferenced static functions).

2012-09-18  Laine Stump  <laine@laine.org>

	network: reorganize dnsmasq and radvd config file / startup
	This patch splits the starting of dnsmasq and radvd into multiple
	files, and adds new networkRefreshXX() and networkRestartXX()
	functions for each. These new functions are currently commented out
	because they won't be used until the next commit, and the compile options
	require all static functions to be used.

	networkRefreshXX() - rewrites any file-based config for dnsmasq/radvd,
	and sends SIGHUP to the process to make it reread its config. If the
	program isn't already running, it's just started.

	networkRestartXX() - kills the given program, waits for it to exit
	(see the comments in the function networkKillDaemon()), then calls
	networkStartXX().

	This commit is here mostly as a checkpoint to verify no change in
	functional behavior after refactoring networkStartXX() functions to
	fit in with these new functions.

	conf: implement NetworkObj backend of virNetworkUpdate API
	virNetworkObjUpdate takes care of all virNetworkUpdate-related changes
	to the data stored in the in-memory virNetworkObj list. It should be
	called by network drivers that use this in-memory list.

	virNetworkObjUpdate *does not* take care of updating any disk-based
	copies of the config, nor does it perform any other operations
	necessary to have the new config data take effect (e.g. it won't
	re-write dnsmasq host files, nor will it send a SIGHUP to dnsmasq) -
	those things should all be taken care of in the network driver
	function that calls virNetworkObjUpdate (assuming that it returns
	success).

2012-09-18  Laine Stump  <laine@laine.org>

	network: utility functions for updating network config
	These new functions are highly inspired by those in domain_conf.c (but
	not identical), and are intended to make it simpler to update the
	various combinations of live/persistent network configs.

	The network driver wasn't previously as careful about the separation
	between the live "status" in network->def and the persistent "config"
	in network->newDef (or sometimes in network->def). This series
	attempts to remedy some of that, but probably doesn't go all the way
	(enough to get these functions working and enable continued work on
	virNetworkUpdate though).

	bridge_driver.c and test_driver.c were updated in a few places to take
	advantage of the new functions and/or account for changes in argument
	lists.

	which locks virDomainObjPtr. Then qemuAgentClose() is called
	(with domain object locked) which eventually calls qemuAgentDispose()
	and qemuProcessHandleAgentDestroy(). This tries to lock the
	domain object again. Hence the deadlock.

	blockjob: add virsh blockcommit
	The new command 'virsh blockcommit $dom $disk' requests the start
	of an asynchronous commit operation across the entire chain of
	$disk.  Further arguments can fine-tune which portion of the
	chain is committed.  Existing 'virsh blockjob' commands can then
	track the status, change the bandwidth, or abort the commit job.

	With a bit more on the command line, 'virsh blockcommit $dom $disk
	--wait --verbose' can be used for blocking behavior, with visual
	feedback on the overall status, and can be canceled with Ctrl-C.

	The overall design, including the wait loop logic, borrows heavily
	from the existing blockpull command.

	* tools/virsh-domain.c (cmdBlockCommit): New function.
	* tools/virsh.pod (blockcommit): Document it.

2012-09-18  Eric Blake  <eblake@redhat.com>

	blockjob: add virDomainBlockCommit
	A block commit moves data in the opposite direction of block pull.
	Block pull reduces the chain length by dropping backing files after
	data has been pulled into the top overlay, and is always safe; block
	commit reduces the chain length by dropping overlays after data has
	been committed into the backing file, and any files that depended
	on base but not on top are invalidated at any point where they have
	unallocated data that is now pointing to changed contents in base.
	Both directions are useful, however: a qcow2 layer that is more than
	50% allocated will typically be faster with a pull operation, while
	a qcow2 layer with less than 50% allocation will be faster as a
	commit operation.  Committing across multiple layers can be more
	efficient than repeatedly committing one layer at a time, but
	requires extra support from the hypervisor.

	This API matches Jeff Cody's proposed qemu command 'block-commit':
	https://lists.gnu.org/archive/html/qemu-devel/2012-09/msg02226.html

	Jeff's command is still in the works for qemu 1.3, and may gain
	further enhancements, such as the ability to control on-error
	handling (it will be comparable to the error handling Paolo is
	adding to 'drive-mirror', so a similar solution will be needed
	when I finally propose virDomainBlockCopy with more functionality
	than the basics supported by virDomainBlockRebase).  However, even
	without qemu support, this API will be useful for _offline_ block
	commits, by wrapping qemu-img calls and turning them into a block
	job, so this API is worth committing now.

	For some examples of how this will be implemented, all starting
	with the chain: base <- snap1 <- snap2 <- active

	+ These are equivalent:
	 virDomainBlockCommit(dom, disk, NULL, NULL, 0, 0)
	 virDomainBlockCommit(dom, disk, NULL, "active", 0, 0)
	 virDomainBlockCommit(dom, disk, "base", NULL, 0, 0)
	 virDomainBlockCommit(dom, disk, "base", "active", 0, 0)
	but cannot be implemented for online qemu with round 1 of
	Jeff's patches; and for offline images, it would require
	three back-to-back qemu-img invocations unless qemu-img
	is patched to allow more efficient multi-layer commits;
	the end result would be 'base' as the active disk with
	contents from all three other files, where 'snap1' and
	'snap2' are invalid right away, and 'active' is invalid
	once any further changes to 'base' are made.

	+ These are equivalent:
	 virDomainBlockCommit(dom, disk, "snap2", NULL, 0, 0)
	 virDomainBlockCommit(dom, disk, NULL, NULL, 0, _SHALLOW)
	they cannot be implemented for online qemu, but for offline,
	it is a matter of 'qemu-img commit active', so that 'snap2'
	is now the active disk with contents formerly in 'active'.

	+ Similarly:
	 virDomainBlockCommit(dom, disk, "snap2", NULL, 0, _DELETE)
	for an offline domain will merge 'active' into 'snap2', then
	delete 'active' to avoid leaving a potentially invalid file
	around.

	+ This version:
	 virDomainBlockCommit(dom, disk, NULL, "snap2", 0, _SHALLOW)
	can be implemented online with 'block-commit' passing a base of
	snap1 and a top of snap2; and can be implemented offline by
	'qemu-img commit snap2' followed by 'qemu-img rebase -u
	-b snap1 active'

	* src/libvirt.c (virDomainBlockCommit): Implement it.

	qemu: drop unused arguments for dump-guest-memory

	build: Fix build failure on non-linux platform

2012-09-18  Laine Stump  <laine@laine.org>

	conf: avoid freeing network object with undestroyed mutex
	virNetworkAssignDef was allocating a new network object, initing and
	grabbing its lock, then potentially freeing it without unlocking or
	destroying the lock. In practice 1) this will probably never happen,
	and 2) even if it did, the lock implementation used on most (all?)
	platforms doesn't actually hold any resources for an initialized or
	held lock, but it still bothered me, so I moved the realloc that could
	lead to this bad situation earlier in the function, and now the mutex
	isn't inited or locked until we are assured of complete success.

	conf: separate functions to parse DHCPHostDef and DHCPRangeDef
	These two objects were previously always parsed as a part of an IpDef,
	but we will now need to be able to parse them on their own for
	virNetworkUpdate(). Split the parsing functions out, with no
	functional changes.

	When generating RPC protocol messages, it's strictly needed to have a

	a possibility to make the daemon segfault with newer virsh (version of

	The problem is that the skipped numbers will get func filled with

	snapshot: fix rollback failure in transaction mode
	BZ:https://bugzilla.redhat.com/show_bug.cgi?id=843372
	when qemu supports the 'transaction' monitor command,
	and libvirt's --reuse-ext flag was not specified, libvirt created
	a stub file with zero size in first place. After the failure of
	QEMU transaction command performing qcow2 snapshots on more than
	one drives, the stub file is left behind with non-empty
	by the QEMU transaction command.
	In order to unlink the file, the patch removes the file size checking.

	Steps to reproduce the issue:
	Steps:
	 1, Create a qemu instance with two drive images of qcow2 type (root user)
	    /usr/libexec/qemu-kvm -m 1024 -smp 1 -name "rhel6u1" \
	      -drive file=/var/lib/libvirt/images/firstqcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none
	      -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x5,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 \
	      -drive file=/var/lib/libvirt/images/secondqcow2,if=none,id=drive-virtio-disk1,format=qcow2,cache=none \
	      -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x7,drive=drive-virtio-disk1,id=virtio-disk1 -qmp stdio

	 2, Initialize qemu qmp
	    {"execute":"qmp_capabilities"}

	 3, Remove the second drive image file
	    rm -f /var/lib/libvirt/images/secondqcow2

	 4, Run 'transaction' command with snapshot qemu commands in.
	    {"execute":"transaction","arguments":
	      {"actions":
	        [{"type":"blockdev-snapshot-sync","data":
	          {"device":"drive-virtio-disk0","snapshot-file":"/var/lib/libvirt/images/firstqcow2-snapshot.img","format":"qcow2"}
	         },
	         {"type":"blockdev-snapshot-sync","data":
	          {"device":"drive-virtio-disk1","snapshot-file":"/var/lib/libvirt/images/secondqcow2-snapshot.img","format":"qcow2"}
	         }]
	      },
	   "id":"libvirt-6"}

	 5, Got the error as follows:
	    {"id": "libvirt-6",
	      "error": {"class": "OpenFileFailed", "desc": "Could not open '/var/lib/libvirt/images/secondqcow2-snapshot.img'",
	                "data": {"filename": "/var/lib/libvirt/images/secondqcow2-snapshot.img"}
	               }
	    }

	 6, List first newly-created snapshot file:
	    -rw-r--r--. 1 root root     262144 Sep 13 11:43 firstqcow2-snapshot.img

	build: don't fail if libnl-3 is not found
	Commit 9298bfb changed configure to split the libnl into two
	separate pkg config checks instead of nesting the second check
	on the failure path of the first.  But the default pkg config
	behavior is to abort configure if a check fails.  Since we have
	a second check lined up, we need an explicit failure case that
	does not abort if the first check fails.

	Meanwhile, commit 51b708c is reverted.  It did not fix any
	behavior, and in fact, introduced a regression to the fallback
	case when the user explicitly sets $LIBNL_CFLAGS.

	conf: avoid libvirt crash with empty address guestfwd channel
	The 'def->target.addr' hasn't been initialized in virDomainChrDefNew() and
	its value is always '0xffffffff', in addition, the following test scenario
	hasn't also include 'address' element in channel XML block, so the branch
	'if (addrStr == NULL)' is hit in virDomainChrDefParseTargetXML(), the
	programming jumps to 'error' label to release relevant resources, and the
	statement 'if (VIR_ALLOC(def->target.addr) < 0)' hasn't been executed then
	the virDomainChrDefFree() will free 'def->target.addr'(0xffffffff) via
	VIR_FREE(), which results in libvirt crash, to use valgrind can also
	find a 'Invalid free() / delete / delete[]' error. This patch just adjusts
	codes order to initialize 'def->target.addr' firstly.

	With this patch, libvirt hasn't crash and can get a expected error message "
	XML error: guestfwd channel does not define a target address".

	How to reproduce?

	1. define a guest with the following channel XML configuration

	$ cat foo.xml
	<snip>
	    <channel type='pty'>
	      <target type='guestfwd'/>
	    </channel>
	</snip>

	$ virsh define foo.xml

	2. actual result

	error: Failed to define domain from /tmp/foo.xml
	error: End of file while reading data: Input/output error
	error: Failed to reconnect to the hypervisor

	GDB debugger information:

	Fix data types used for list sizes in QEMU capabilities
	The QEMU capabilities APIs used a misc of 'int' and
	'unsigned int' for variables relating to array sizes.
	Change all these to use 'size_t'

	Add API for copying instances of the qemuCapsPtr object
	To allow each VM instance to record additional capabilities
	without affecting other VMs, there needs to be a way to do
	a deep copy of the qemuCapsPtr object

	Add ability to store other metadata in the qemu capabilities object
	Add struct fields and APIs to allow the qemu capabilities object
	to store version, arch, machines & cpu names, etc

	Make qemuCapsProbeCommand static
	The qemuCapsProbeCommand API is only used by the capabilities
	code, so can be static

	Turn QEMU capabilities object into a full virObjectPtr
	The current qemu capabilities are stored in a virBitmapPtr
	object, whose type is exposed to callers. We want to store
	more data besides just the flags, so we need to move to a
	struct type. This object will also need to be reference
	counted, since we'll be maintaining a cache of data per
	binary. This change introduces a 'qemuCapsPtr' virObject
	class. Most of the change is just renaming types and
	variables in all the callers

	Allow caps to be NULL when creating virDomainObjPtr instances
	If no private data needs to be maintained, it can be useful
	to create virDomainObjPtr instances without having a virCapsPtr
	instance around. Adapt the virDomainObjNew() function to allow
	for a NULL caps

	Wait to receive QMP greeting before sending any monitor commands
	Technically speaking we should wait until we receive the QMP
	greeting message before attempting to send any QMP monitor
	commands. Mostly we've got away with this, but there is a race
	in some QEMU which cause it to SEGV if you sent it data too
	soon after startup. Waiting for the QMP greeting avoids the
	race

	Add a virBitmapCopy API
	Add an API allowing flags from one virBitmapPtr to be copied

	build: force libnl1 if netcf also used libnl1
	Recent spec file changes ensure that in distro situations, netcf
	and libvirt will link against the same libnl in order to avoid
	dumping core.  But for every-day development, if you use F17 and
	have the libnl3-devel headers available, libvirt was blindly
	linking against libnl3 even though F17 netcf still links against
	libnl1, making testing a self-built binary on F17 impossible.

	By making configure a little bit smarter, we can avoid this
	situation - we merely skip the probe of libnl-3 if we can prove
	that netcf is still using libnl-1.  I intentionally wrote the
	test so that we still favor libnl-3 if netcf is not installed or
	if we couldn't use ldd to determine things.

	Defaults being what they are, someone will invariably complain
	that our smarts were wrong.  Never fear - in that case, just run
	./configure LIBNL_CFLAGS=..., where the fact that you set
	LIBNL_CFLAGS (even to the empty string) will go back to probing
	for libnl-3, regardless of netcf's choice.

	* configure.ac (LIBNL): Don't probe libnl3 if netcf doesn't use it.

	Backcompt for console devices in virDomainDeviceInfoIterate
	Historically, the first <console> element is treated as the
	alias of a <serial> device. In the virDomainDeviceInfoIterate,
	This situation is not considered. It still handles the first <console>
	element as another devices, which means that for console[0] with
	serial targetType, it calls callback function another time.
	It will cause the problem of address conflicts when assigning
	spapr-vio address for serial device on pSeries guest.

	For pSeries guest, the serial configuration in the xml file
	is as the following:
	         <serial type='pty'>
	               <target port='0'/>
	               <address type='spapr-vio'/>
	          </serial>

	Console configuration is default, the dumped xml file is as the following:
	   <serial type='pty'>
	      <source path='/dev/pts/5'/>
	      <target port='0'/>
	      <alias name='serial0'/>
	      <address type='spapr-vio' reg='0x30000000'/>
	    </serial>
	    <console type='pty' tty='/dev/pts/5'>
	      <source path='/dev/pts/5'/>
	      <target type='serial' port='0'/>
	      <alias name='serial0'/>
	      <address type='spapr-vio' reg='0x30000000'/>
	    </console>

	It shows that the <console> device is the alias of serial device.
	So its address is the same as the serial device. When detecting
	the conflicts in the qemuAssignSpaprVIOAddress the first console
	and the serial device conflicts because virDomainDeviceInfoIterate()
	still handle these as two different devices, and in the qemuAssignSpaprVIOAddress(),
	it will compare these two devices' addressed. If they have same address,
	it will report address conflict error.

	So this patch is to handle the first console which targetType is serial
	as the alias of serial device to avoid address conflicts error reported.

	Fix unwanted closing of libvirt client connection
	e5a1bee07 introduced a regression in Boxes: when Boxes is left idle
	(it's still doing some libvirt calls in the background), the
	libvirt connection gets closed after a few minutes. What happens is
	that this code in virNetClientIOHandleOutput gets triggered:

	if (!thecall)
	    return -1; /* Shouldn't happen, but you never know... */

	and after the changes in e5a1bee07, this causes the libvirt connection
	to be closed.

	Upon further investigation, what happens is that
	virNetClientIOHandleOutput is called from gvir_event_handle_dispatch
	in libvirt-glib, which is triggered because the client fd became
	writable. However, between the times gvir_event_handle_dispatch
	is called, and the time the client lock is grabbed and
	virNetClientIOHandleOutput is called, another thread runs and
	completes the current call. 'thecall' is then NULL when the first
	thread gets to run virNetClientIOHandleOutput.

	After describing this situation on IRC, danpb suggested this:

	11:37 < danpb> In that case I think the correct thing would be to change
	               'return -1' above to 'return 0' since that's not actually an
	               error - its a rare, but expected event

	which is what this patch is doing. I've tested it against master
	libvirt, and I didn't get disconnected in ~10 minutes while this
	happens in less than 5 minutes without this patch.

	docs: point out git send-email location, be more stern about make check
	An email came to libvir-list wondering why the git send-email command
	was missing in spite of having git installed; this is due to the
	send-email command being in a sub-package of the main git package.

	While touching the hacking file, I thought it would be useful to 1)
	indicate the location of the source (docs/hacking.html.in) in the

	"make check" and "make syntax-check" a bit more stern.

	build: fix build on older gcc
	On RHEL 6.2, gcc 4.4.6 complains:
	cc1: warning: command line option "-Wenum-compare" is valid for C++/ObjC++ but not for C
	which in turn breaks a -Werror build.

	Meanwhile, in Fedora 17, gcc 4.7.0, -Wenum-compare has been enhanced
	to also work on C, but at the same time, it is documented that -Wall
	now implicitly includes -Wenum-compare.

	Therefore, it is sufficient to remove explicit checks for this option,
	avoiding the warning from older gcc while still getting the
	compile-time safety from newer gcc.

	* m4/virt-compile-warnings.m4 (-Wenum-compare): Omit explicit check.

	events: Fix domain event race on client disconnect
	GNOME Boxes sometimes stops getting domain events from libvirtd, even
	after restarting it. Further investigation in libvirtd shows that
	events are properly queued with virDomainEventStateQueue, but the
	timer virDomainEventTimer which flushes the events and sends them to
	the clients never gets called. Looking at the event queue in gdb
	shows that it's non-empty and that its size increases with each new
	events.

	virDomainEventTimer is set up in virDomainEventStateRegister[ID]
	when going from 0 client connecte to 1 client connected, but is
	initially disabled. The timer is removed in
	virDomainEventStateRegister[ID] when the last client is disconnected
	(going from 1 client connected to 0).

	This timer (which handles sending the events to the clients) is
	enabled in virDomainEventStateQueue when queueing an event on an
	empty queue (queue containing 0 events). It's disabled in
	virDomainEventStateFlush after flushing the queue (ie removing all
	the elements from it). This way, no extra work is done when the queue
	is empty, and when the next event comes up, the timer will get
	reenabled because the queue will go from 0 event to 1 event, which
	triggers enabling the timer.

	However, with this Boxes bug, we have a client connected (Boxes), a
	non-empty queue (there are events waiting to be sent), but a disabled
	timer, so something went wrong.

	When Boxes connects (it's the only client connecting to the libvirtd
	instance I used for debugging), the event timer is not set as expected
	(state->timer == -1 when virDomainEventStateRegisterID is called),
	but at the same time the event queue is not empty. In other words,
	we had no clients connected, but pending events. This also explains
	why the timer never gets enabled as this is only done when an event
	is queued on an empty queue.

	I think this can happen if an event gets queued using
	virDomainEventStateQueue and the client disconnection happens before
	the event timer virDomainEventTimer gets a chance to run and flush
	the event. In this situation, virDomainEventStateDeregister[ID] will
	get called with a non-empty event queue, the timer will be destroyed
	if this was the only client connected. Then, when other clients connect
	at a later time, they will never get notified about domain events as
	the event timer will never get enabled because the timer is only
	enabled if the event queue is empty when virDomainEventStateRegister[ID]
	gets called, which will is no longer the case.

	To avoid this issue, this commit makes sure to remove all events from
	the event queue when the last client in unregistered. As there is
	no longer anyone interested in receiving these events, these events
	are stale so there is no need to keep them around. A client connecting
	later will have no interest in getting events that happened before it
	got connected.

	Fix location of SELinux mount during RPM builds
	When building RPMs the host kernel cannot be assumed to match
	the target OS kernel. Thus auto-detecting /selinux vs
	/sys/fs/selinux based on the host kernel can result in the
	wrong choice (eg F18 builds on a RHEL6 host kernel)

	Don't assume use of /sys/fs/cgroup
	The introduction of /sys/fs/cgroup came in fairly recent kernels.
	Prior to that time distros would pick a custom directory like
	/cgroup or /dev/cgroup. We need to auto-detect where this is,
	rather than hardcoding it

	Introduce a test suite for the JSON monitor
	Take advantage of the previously added monitor helpers to
	create a test suite for the QEMU JSON monitor impl. As a
	proof of concept, this tests the 'qemuMonitorGetStatus'
	implementation

	Add helper library for testing the qemu monitor code
	To be able to test the QEMU monitor code, we need to have a fake
	QEMU monitor server. This introduces a simple (dumb) framework
	that can do this. The test case registers a series of items to
	be sent back as replies to commands that will be executed. A
	thread runs the event loop looking for incoming replies and
	sending back this pre-registered data. This allows testing all
	QEMU monitor code that deals with parsing responses and errors
	from QEMU, without needing QEMU around

	Add non-null annotations to qemuMonitorOpen
	Add some non-null annotations to qemuMonitorOpen and also

	virsh: Update only changed scheduler tunables
	When setting the cpu tunables in virsh you are able to update only a
	subset of them. Virsh while doing the update updated all of the
	tunables, changed ones with new values and unchanged with old ones.
	This is unfortunate as it:
	a) might overwrite some other change by a race condition (unprobable)
	b) fails with range checking as some of the old values saved might be
	   out of range

	This patch changes the update procedure so that only the changed value
	is updated on the host.

	This patch also fixes a very unprobable memory leak if the daemon would
	return a string tunable parameter, as the typed parameter array was not
	cleared.

	This patch adds a separate range check, that improves error messages
	when changing live config and adds the check for persistent config.

	specify invalid values in the XML.

	build: require netcf-0.2.2 when installing on Fedora18+
	A previous patch forced libnl-3 and netcf-0.2.2 (which itself requires
	libnl-3) when *building* for Fedora 18+ (and RHEL 7+), but the
	install-time Requires: for netcf has always been implicit due to
	libvirtd linking with libnetcf.so. However, the since the API of netcf
	didn't change when it was rebuilt to use libnl-3, the internal library
	version didn't change either, making it possible (from rpm's point of
	view) to upgrade libvirt without upgrading netcf (in reality, that
	leads to a segfault - see
	https://bugzilla.redhat.com/show_bug.cgi?id=853381).

	qemu: don't pin all the cpus
	This is another fix for the emulator-pin series. When going through

	Most likely this problem arose because of the patch I pushed
	in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039.
	Previously, gnulib required timeval's tv_sec to be
	the same size as time_t.  But now, it requires only that
	tv_sec be big enough to hold a time_t.

	This patch was needed for Emacs.  Without the patch, gnulib
	replaced struct timeval on OpenBSD, and this messed up
	utimens.c, and Emacs wouldn't build.

	Alternatively, gnulib could substitute its own struct timeval
	for the system's, wrapping every struct timeval-using function
	(gettimeofday, futimesat, futimes, lutimes, etc.  That'd be
	more work, though.  And it would introduce some performance
	issues with gettimeofday, which is supposed to be fast.

	I've been trying to get away from using struct timeval,
	and to use the higher-resolution struct timespec instead,
	so messing with these obsolescent interfaces has been
	lower priority for me.  But if someone wants to take the
	more-ambitious approach that'd be fine, I expect.

	For this particular case, though, how about if we avoid
	the problem entirely?  libvirt doesn't need to use struct
	timeval here at all.  It makes libvirt smaller and probably
	faster, and it ports to OpenBSD without messing with gnulib.

	network: get vlan info for Open vSwitch interfaces from proper source
	This bug was revealed by the crash described in

	  https://bugzilla.redhat.com/show_bug.cgi?id=852383

	The vlan info pointer sent to virNetDevOpenvswitchAddPort should never
	be non-NULL unless there is at least one tag. The factthat such a vlan
	info pointer was receveid pointed out that a caller was passing the
	wrong pointer. Instead of sending &net->vlan, the result of
	virDomainNetGetActualVlan(net) should be sent - that function will
	look for vlan info in net->data.network.actual->vlan, and in cany case
	return NULL instead of a pointer if the vlan info it finds has no
	tags.

	Aside from causing the crash, sending a hardcoded &net->vlan has the

	Fix configuration of QEMU security drivers
	If no 'security_driver' config option was set, then the code
	just loaded the 'dac' security driver. This is a regression
	on previous behaviour, where we would probe for a possible
	security driver. ie default to SELinux if available.

	This changes things so that it 'security_driver' is not set,
	we once again do probing. For simplicity we also always
	create the stack driver, even if there is only one driver
	active.

	The desired semantics are:

	 - security_driver not set
	     -> probe for selinux/apparmour/nop
	     -> auto-add DAC driver
	 - security_driver set to a string
	     -> add that one driver
	     -> auto-add DAC driver
	 - security_driver set to a list
	     -> add all drivers in list
	     -> auto-add DAC driver

	It is not allowed, or possible to specify 'dac' in the

	build: work with older libnl1 headers
	Ubuntu 10.04 shipped with out-of-the-box libnl1 headers, which
	assumed the old gcc semantics of 'extern inline' as a C89 extension:
	the function will _always_ be inline if it is used, and that
	it may be declared extern inline in headers without a definition,
	as long as the definition occurs before any use.  But when C99
	added 'extern inline' as a mandatory feature of the language, with
	slightly different semantics than gcc (the function MUST have
	external linkage, and the inline definition MUST be present
	alongside any declaration, where the compiler can then choose
	which of the two versions to use), this rendered the use of
	'inline' in libnl's header obsolete.  Most distros already solved
	this by removing 'inline' (the resulting 'extern' is correct,
	regardless of gcc semantics), and libnl-3 does not have the
	problem (where it has switched to 'static inline' instead, again
	with the definition present, and again, our hack will result in
	plain 'static' with no ill effects).  But for the case of building
	out of the box, we hack around the broken Ubuntu header.

	qemu: Fix define logic

	Currently, when guest agent is configured but not responsive

	specfile: require libnl3 for Fedora >= 18 and RHEL >= 7
	Everything is ready in both netcf and libvirt to switch over to libnl3
	in future releases of both Fedora and RHEL. This needs to be done more
	or less simultaneously in both packages, though, because you can't mix
	libnl1.1 and libnl3 in the same process (e.g. libvirtd using
	libnl-3.so and libnetcf.so, while libnetcf.so uses libnl.so)

	This patch does two things when fedora >= 18 || rhel >= 7):

	  1) requires libnl3-devel
	  2) requires netcf-devel-0.2.2 or greater

	(the idea is that a similar patch is going into netcf's specfile, so
	that when a build of netcf is done on F18 or later (or RHEL7 or later)
	netcf will be guaranteed to be built with libnl3 rather than
	libnl-1.1)

2012-08-26  Laine Stump  <laine@laine.org>

	build: add LIBNL_CFLAGS to build of libvirt_lxc
	When libvirt_lxc is built, it uses the utility library and #includes
	virnetdev.h, which #includes virnetlink.h, which includes
	<netlink/msg.h>.

	Normally, the netlink include directory would be just off
	/usr/include, so that wouldn't create a problem, but on Fedora and
	RHEL systems using libnl3, the libnl includes have been moved into
	/usr/include/libnl3 (to allow concurrent installation of libnl-1.1).

	All other binaries that need it have added $(LIBNL_CFLAGS) to their
	CFLAGS, but not libvirt_lxc, so it fails to build on Fedora and RHEL
	that have only libnl3-devel installed. This was previously unnoticed
	because everyone was building with libnl headers in
	/usr/include/netlink (even on systems with the headers in
	/usr/include/libnl3/netlink, many people (like me) usually also have
	the libnl1.1 headers in /usr/include/netlink).

	This patch adds the necessary CFLAGS for libvirt_lxc.

	Note that we don't need to add $(LIBNL_LIBS) to the LDADD for this
	binary, because it never directly calls libnl functions, but only
	calls them indirectly through the util library, which it's already
	linking against.

	xen-xs: fix uuid of renamed domain
	When the XenStore tdb lives persistently and is not cleared between host
	reboots, Xend (version 3.4 and 4.1) re-creates the domain information
	located in XenStore below /vm/$UUID. (According to the xen-3.2-commit
	hg265950e3df69 to fix a problem when locally migrating a domain to the
	host itself.)

	When doing so a version number is added to the UUID separated by one
	dash, which confuses xenStoreDomainIntroduced(): It iterates over all
	domains and tries to lookup all inactive domains using
	xenStoreDomainGetUUID(), which fails if the running domain is renamed:
	virUUIDParse() fails to parse the versioned UUID and the domain is
	flagged as missing. When this happens the function delays .2s and
	re-tries 20 times again, multiplied by the number of renamed VMs.
	  14:48:38.878: 4285: debug : xenStoreDomainIntroduced:1354 : Some domains were missing, trying again

	This adds a significant delay:

	nwfilter: don't log error if firewalld is disabled, improve diagnostics
	The original patch to support firewalld in nwfilter wasn't personally
	checking the exit status of firewall-cmd, but was instead sending NULL
	in the *exitstatus arg, which meant that virCommandWait would log an
	error just for the exit status being non-0 (and a "more scary than
	useful" error at that).

	We don't want to treat this as an error, though, just as a reason to
	use standard (ip|eb)tables commands instead of firewall-cmd.

	This patch modifies the virCommandRun in the nwfilter code to request
	status back from the caller. This avoids virCommandWait logging an
	error message, and allows the caller to do as it likes after examining
	the status.

	The VIR_DEBUG() logged when firewalld is enabled has also been
	reworded and changed to a VIR_INFO, and a similar VIR_INFO has been
	added in the case that firewalld is *not* found+enabled.

	request an exit status from virCommandRun (thus assuring that

	functions believing that the call to "vzlist" was successful, even
	though it may have encountered an error.

	client: Change default location of known_hosts file for libssh2 layer
	Unfortunately libssh2 doesn't support all types of host keys that can be
	saved in the known_hosts file. Also it does not report that parsing of
	the file failed. This results into truncated known_hosts files where the
	standard client stores keys also in other formats (eg.
	ecdsa-sha2-nistp256).

	This patch changes the default location of the known_hosts file into the
	libvirt private configuration directory, where it will be only written
	by the libssh2 layer itself. This prevents trashing user's known_host
	file.

	atomic: mark header functions static
	When gcc atomic intrinsics are not available (such as on RHEL 5

	nwfilter: provide basic support for firewalld
	This patch provides basic support for using firewalld's firewall-cmd
	rather than then plain eb/ip(6)tables commands.

2012-08-22  Thomas Woerner  <twoerner@redhat.com>

	network: use firewalld instead of iptables, when available
	* configure.ac, spec file: firewalld defaults to enabled if dbus is
	  available, otherwise is disabled. If --with_firewalld is explicitly
	  requested and dbus is not available, configure will fail.

	* bridge_driver: add dbus filters to get the FirewallD1.Reloaded
	  signal and DBus.NameOwnerChanged on org.fedoraproject.FirewallD1.
	  When these are encountered, reload all the iptables reuls of all
	  libvirt's virtual networks (similar to what happens when libvirtd is
	  restarted).

	* iptables, ebtables: use firewall-cmd's direct passthrough interface
	  when available, otherwise use iptables and ebtables commands. This
	  decision is made once the first time libvirt calls
	  iptables/ebtables, and that decision is maintained for the life of
	  libvirtd.

	* Note that the nwfilter part of this patch was separated out into
	  another patch by Stefan in V2, so that needs to be revised and
	  re-reviewed as well.

	================

	All the configure.ac and specfile changes are unchanged from Thomas'
	V3.

	V3 re-ran "firewall-cmd --state" every time a new rule was added,
	which was extremely inefficient.  V4 uses VIR_ONCE_GLOBAL_INIT to set
	up a one-time initialization function.

	The VIR_ONCE_GLOBAL_INIT(x) macro references a static function called
	vir(Ip|Eb)OnceInit(), which will then be called the first time that
	the static function vir(Ip|Eb)TablesInitialize() is called (that
	function is defined for you by the macro). This is
	thread-safe, so there is no chance of any race.

	IMPORTANT NOTE: I've left the VIR_DEBUG messages in these two init
	functions (one for iptables, on for ebtables) as VIR_WARN so that I
	don't have to turn on all the other debug message just to see
	these. Even if this patch doesn't need any other modification, those
	messages need to be changed to VIR_DEBUG before pushing.

	This one-time initialization works well. However, I've encountered
	problems with testing:

	1) Whenever I have enabled the firewalld service, *all* attempts to
	call firewall-cmd from within libvirtd end with firewall-cmd hanging
	internally somewhere. This is *not* the case if firewall-cmd returns
	non-0 in response to "firewall-cmd --state" (i.e. *that* command runs
	and returns to libvirt successfully.)

	2) If I start libvirtd while firewalld is stopped, then start
	firewalld later, this triggers libvirtd to reload its iptables rules,
	however it also spits out a *ton* of complaints about deletion failing
	(I suppose because firewalld has nuked all of libvirt's rules). I
	guess we need to suppress those messages (which is a more annoying
	problem to fix than you might think, but that's another story).

	3) I noticed a few times during this long line of errors that
	firewalld made a complaint about "Resource Temporarily
	unavailable. Having libvirtd access iptables commands directly at the
	same time as firewalld is doing so is apparently problematic.

	4) In general, I'm concerned about the "set it once and never change
	it" method - if firewalld is disabled at libvirtd startup, causing
	libvirtd to always use iptables/ebtables directly, this won't cause
	*terrible* problems, but if libvirtd decides to use firewall-cmd and
	firewalld is later disabled, libvirtd will not be able to recover.

	sanlock: Provide better error if lockspace directory is missing
	Generating "Unable to add lockspace /lock/space/dir/__LIBVIRT__DISKS__:

	/lock/space/dir/__LIBVIRT__DISKS__: parent directory does not exist or

	daemon: Autodetect lock driver directory
	When running libvirtd from a build directory, libvirtd would load lock
	drivers from system directory unless explicitly overridden by setting
	LIBVIRT_LOCK_MANAGER_PLUGIN_DIR environment variable. Since we already
	autodetect driver directory if libvirt is build with driver modules, we

	build: silence stupid gcc warning on STREQ_NULLABLE
	Our existing STRNEQ_NULLABLE() triggered a warning in gcc 4.7 when
	used with a literal NULL argument:

	qemumonitorjsontest.c: In function 'testQemuMonitorJSONGetMachines':
	qemumonitorjsontest.c:289:5: error: null argument where non-null required (argument 1) [-Werror=nonnull]

	even though the strcmp is provably dead when a null argument is
	present.  Squelch the warning by refactoring things so that gcc
	never sees strcmp() called with NULL arguments (we still compare
	NULL as not equal to "", this rewrite merely aids gcc).

	Next, gcc has a valid warning about a literal NULLSTR(NULL):

	qemumonitorjsontest.c:289:5: error: invalid application of 'sizeof' to a void type [-Werror=pointer-arith]

	Of course, you'd never write NULLSTR(NULL) directly, but it is
	handy to use through macros.  But the entire part about verify_true()
	is unnecessary - gcc already warns about type mismatch with ?:,
	without needing to make it more complex.

	* src/internal.h (STREQ_NULLABLE, STRNEQ_NULLABLE): Avoid gcc 4.7
	stupidity.
	(NULLSTR): Simplify, to allow passing compile-time constants.

	Fix parsing of uid/gid on Mingw32
	The DAC security driver uses the virStrToLong_ui function to
	parse the uid/gid out of the seclabel string. This works on
	Linux where 'uid_t' is an unsigned int, but on Mingw32 it is
	just an 'int'. This causes compiler warnings about signed/
	unsigned int pointer mis-match.

	To avoid this, use explicit 'unsigned int ouruid' local
	vars to pass into virStrToLong_ui, and then simply assign
	to the 'uid_t' type after parsing

	libssh2_transport: Use libssh2 driver code in remote driver
	This patch adds URI options to support libssh2 transport in the remote
	driver.

	A new transport sceme is introduced eg. "qemu+libssh2://..." that
	utilizes the libssh2 code added in previous patches.

	The libssh2 code requires the authentication callback to be able to
	perform keyboard-interactive authentication or to ask t passprhases or
	add host keys to known hosts database.

	Added URI components:
	- known_hosts -  path to a knownHosts file in OpenSSH format to check
	                 for known ssh host keys
	- known_hosts_verify - how to deal with server key verification:
	                            * "normal" (default) - ask to add new keys
	                            * "auto" - automaticaly add new keys
	                            * "ignore" - don't validate host keys
	- sshauth - authentication methods to use. Default is
	            "agent,privkey,keyboard-interactive". It's a comma separated
	            string of methods to try while authenticating. The order is
	            preserved. Some of the methods may require additional
	            parameters.

	Locations of the known_hosts file and private keys are set to default
	values if they're present. (~/.ssh/known_hosts, ~/.ssh/id_rsa,
	                            ~/.ssh/id_dsa)

	libssh2_transport: add main libssh2 transport implementation
	This patch adds helper functions that enable us to use libssh2 in
	conjunction with libvirt's virNetSockets for ssh transport instead of
	spawning "ssh" client process.

	This implemetation supports tunneled plaintext, keyboard-interactive,
	private key, ssh agent based and null authentication. Libvirt's Auth
	callback is used for interaction with the user. (Keyboard interactive
	authentication, adding of host keys, private key passphrases). This
	enables seamless integration into the application using libvirt. No
	helpers as "ssh-askpass" are needed.

	Reading and writing of OpenSSH style "known_hosts" files is supported.

	Communication is done using SSH exec channel, where the user may specify
	arbitrary command to be executed on the remote side and reads and writes
	to/from stdin/out are sent through the ssh channel. Usage of stderr is
	not (yet) supported.

	Add test case for SELinux label generation
	This test case validates the correct generation of SELinux labels
	for VMs, wrt the current process label. Since we can't actually
	change the label of the test program process, we create a shared
	library libsecurityselinuxhelper.so which overrides the getcon()
	and setcon() libselinux.so functions. When started the test case
	will check to see if LD_PRELOAD is set, and if not, it will
	re-exec() itself setting LD_PRELOAD=libsecurityselinuxhelper.so

2012-08-21  Daniel P. Berrange  <berrange@redhat.com>

	Honour current sensitivity and category ranges in SELinux label generation
	Currently the dynamic label generation code will create labels
	with a sensitivity of s0, and a category pair in the range
	0-1023. This is fine when running a standard MCS policy because
	libvirtd will run with a label

	  system_u:system_r:virtd_t:s0-s0:c0.c1023

	With custom policies though, it is possible for libvirtd to have
	a different sensitivity, or category range. For example

	  system_u:system_r:virtd_t:s2-s3:c512.c1023

	In this case we must assign the VM a sensitivity matching the
	current lower sensitivity value, and categories in the range
	512-1023

	build: fix build with autoconf 2.59
	Commit 350583c8 broke development on a RHEL 5 box, where the
	ancient Autoconf 2.59 lacks AS_VERSION_STRING.  Rather than
	backport the complex awk script that newer autoconf uses for
	true strverscmp comparisons from the shell, it was easier to
	just open-code a shell case statement.

	Update the remote API
	This patch updates libvirt's API to allow applications to inspect the
	full list of security labels of a domain.

	Support for multiple default security drivers in QEMU config
	This patch updates the key "security_driver" in QEMU config to suport
	both a sigle default driver or a list of default drivers. This ensures
	that it will remain compatible with older versions of the config file.

	Update security layer to handle many security labels
	These changes make the security drivers able to find and handle the
	correct security label information when more than one label is
	available. They also update the DAC driver to be used as an usual
	security driver.

	Multiple security drivers in XML data
	This patch updates the domain and capability XML parser and formatter to
	support more than one "seclabel" element for each domain and device. The
	RNG schema and the tests related to this are also updated by this patch.

	Internal refactory of data structures
	This patch updates the structures that store information about each
	domain and each hypervisor to support multiple security labels and
	drivers. It also updates all the remaining code to use the new fields.

	For network devices allocated from a network with <forward

	the hostdevs array.

	In this case we also need to call qemuPrepareHostDevices just for this

	qemu: support setting vlan tag for <interface type='hostdev'>
	The underlying function to set the vlan tag of an SR-IOV network
	device was already in place (although an extra patch to save/restore
	the original vlan tag was needed), and recent patches added the
	ability to configure a vlan tag. This patch just ties those two
	together.

	An SR-IOV device doesn't support vlan trunking, so if anyone tries to
	configure more than a single tag, or set the trunk flag, and error is
	logged.

2012-08-16  Laine Stump  <laine@laine.org>

	util: properly save/restore original vlan tag for VFs
	When a network device that is a VF of an SR-IOV card was assigned to a
	guest using <interface type='hostdev'>, only the MAC address was being
	saved/restored, but the VLAN tag was left untouched. Up to now we
	haven't actually used vlan tags on SR-IOV devices, so the guest would
	have used whatever was set, and left it the same at the end.

	The patch following this one will hook up the <vlan> element from the
	interface config, so save/restore of the device state needs to also
	include the vlan tag.

	MAC address is being saved as a simple ASCII string in a file named
	for the device under /var/run.  The VLAN tag is now just added at the
	end of that file, after a newline. It might be nicer if the file was
	XML (in case it ever gets more complicated) but at the moment there's
	nothing else on the horizon, and this makes backward compatibility
	easier.

	build: avoid warnings on older gcc
	A previous patch (c606671a) pulled in a newer version of
	stat-time.h from gnulib, which causes some warnings in older gcc:

	  CC     libvirt_driver_storage_la-storage_backend.lo
	cc1: warnings being treated as errors
	In file included from ../../src/storage/storage_backend.c:59:
	../../gnulib/lib/stat-time.h:55: error: no previous prototype for 'get_stat_atime_ns' [-Wmissing-prototypes]

	Upstream gnulib argues that these warnings are stupid (and I agree;
	see <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54113>), and has
	used a modern gcc feature (#pragma GCC diagnostic push) to avoid the
	warning.  But we still aim to compile on RHEL 6.3, with gcc 4.4.6
	(not to mention even older platforms like RHEL 5), and therefore
	the warning trips up our default of development with -Werror.

	It took me a while to figure out how to make our set of warnings
	smaller on older gcc without losing the benefit of the warnings
	when using newer gcc (such as the one on Fedora 17), but this
	should do the trick.

	network: make network driver vlan-aware
	The network driver now looks for the vlan element in network and
	portgroup objects, and logs an error at network define time if a vlan
	is requested for a network type that doesn't support it. (Currently
	vlan configuration is only supported for openvswitch networks, and
	networks used to do hostdev assignment of SR-IOV VFs.)

	At runtime, the three potential sources of vlan information are
	examined in this order: interface, chosen portgroup, network, and the
	first that is non-empty is used.  Another check for valid network type
	is made at this time, since the interface may have requested a vlan (a
	legal thing to have in the interface config, since it's not known
	until runtime if the chosen network will actually support it).

	Since we must also check for domains requesting vlans for unsupported
	connection types even if they are type='network', and since
	networkAllocateActualDevice() is being called in exactly the correct
	places, and has all of the necessary information to check, I slightly
	modified the logic of that function so that interfaces that aren't
	type='network' don't just return immediately. Instead, they also
	perform all the same validation for supported features. Because of
	this, it's not necessary to make this identical check in the other
	three places that would normally require it: 1) qemu domain startup,
	2) qemu device hotplug, 3) lxc domain startup.

	This can be seen as a first step in consolidating network-related
	functionality into the network driver, rather than having copies of
	the same code spread around in multiple places; this will make it
	easier to split the network parts off into a separate daemon, as we've
	discussed recently.

2012-08-16  Laine Stump  <laine@laine.org>

	Each vlan element must have one or more <tag id='n'/> subelements.  If
	there is more than one tag, it is assumed that vlan trunking is being
	requested. If trunking is required with only a single tag, the
	attribute "trunk='yes'" should be added to the toplevel <vlan>
	element.

	Some examples:

	  <interface type='hostdev'/>
	    <vlan>
	      <tag id='42'/>
	    </vlan>
	    <mac address='52:54:00:12:34:56'/>
	    ...
	  </interface>

	  <network>
	    <name>vlan-net</name>
	    <vlan trunk='yes'>
	      <tag id='30'/>
	    </vlan>
	    <virtualport type='openvswitch'/>
	  </network>

	  <interface type='network'/>
	    <source network='vlan-net'/>
	    ...
	  </interface>

	  <network>
	    <name>trunk-vlan</name>
	    <vlan>
	      <tag id='42'/>
	      <tag id='43'/>
	    </vlan>
	    ...
	  </network>

	  <network>
	    <name>multi</name>
	    ...
	    <portgroup name='production'/>
	      <vlan>
	        <tag id='42'/>
	      </vlan>
	    </portgroup>
	    <portgroup name='test'/>
	      <vlan>
	        <tag id='666'/>
	      </vlan>
	    </portgroup>
	  </network>

	  <interface type='network'/>
	    <source network='multi' portgroup='test'/>
	    ...
	  </interface>

	IMPORTANT NOTE: As of this patch there is no backend support for the
	vlan element for *any* network device type. When support is added in
	later patches, it will only be for those select network types that
	support setting up a vlan on the host side, without the guest's
	involvement. (For example, it will be possible to configure a vlan for
	a guest connected to an openvswitch bridge, but it won't be possible
	to do that for one that is connected to a standard Linux host bridge.)

	util: add virNetDevVlanType
	To allow for the possibility of vlan "trunks", which have more than
	one vlan tag associated with them, we need a vlan struct. Since it
	will be used by multiple files in src/util, src/conf, src/network, and
	src/qemu, it must be defined in src/util. Unfortunately there isn't
	currently a common file for simple netdev data definitions, so I
	created a new file.

	schema: fix some problems in network/interface schemas
	<portgroup> allows a <bandwidth> element, but the schema didn't have

	for openvswitch, but the schema didn't allow this.

	Provided information about the defaults that libvirtd uses when running

	Refactor RPC client private data setup
	Currently there is a hook function that is invoked when a
	new client connection comes in, which allows an app to
	setup private data. This setup will make it difficult to
	serialize client state during process re-exec(). Change to
	a model where the app registers a callback when creating

	conf: log error when encountering multiple filterrefs in interface
	Each interface has a single pointer to a filterref object. That
	filterref can itself point to multiple other filterrefs, but at the
	toplevel there is only one.

	The parser had previously just silently overwritten earlier filterrefs
	when a new one was encountered, so the interface was left with
	whichever was the last filterref in the xml, ignoring all the
	others. This patch logs an error when it sees more than one filterref.

	network: add connections counter to networks
	Just as each physical device used by a network has a connections
	counter, now each network has a connections counter which is
	incremented once for each guest interface that connects using this
	network.

	The count is output in the live network XML, like this:

	   <network connections='20'>
	   ...
	   </network>

	It is read-only, and for informational purposes only - it isn't used
	internally anywhere by libvirt.

2012-08-15  Laine Stump  <laine@laine.org>

	network: change cleanup: to success/cleanup/error: in network*() functions
	A later patch will be adding a counter that will be
	incremented/decremented each time an guest interface starts/stops
	using a particular network. For this to work, all types of networks
	need to go through a common return sequence rather than returning
	early. To setup for this, a new success: label is added (when
	necessary), a new error: label is added which does any cleanup
	necessary only for error returns and then does goto cleanup, and early
	returns are changed to goto error if it's a failure, or goto success
	if it's successful. This way the intent of all the gotos is
	unambiguous, and a successful return path never encounters the
	"error:" label.

	conf: output forward device connections count in network XML
	It may be useful for management applications to know which physical
	network devices are in use by guests. This information is already
	available in the network objects, but wasn't output in the XML. This
	patch outputs it when the INACTIVE flag isn't set (and if it's non-0).

	conf: rename interface "usageCount" to "connections"
	I want to include this count in the xml output of networks, but
	calling it "connections" in the XML sounds better than "usageCount", and it
	would be better if the name in the XML matched the variable name.

	In a few places, usageCount was being initialized to 0, but this is
	unnecessary, because VIR_ALLOC_N zero-fills everything anyway.

	removes UsageCount. It ends up being a struct with a single field, but
	I left it as a struct in case we need to add other fields to it in the
	future.

	network: merge relevant virtualports rather than choosing one
	One of the original ideas behind allowing a <virtualport> in an
	interface definition as well as in the <network> definition *and*one
	or more <portgroup>s within the network, was that guest-specific
	parameteres (like instanceid and interfaceid) could be given in the
	interface's virtualport, and more general things (portid, managerid,
	etc) could be given in the network and/or portgroup, with all the bits
	brought together at guest startup time and combined into a single
	virtualport to be used by the guest. This was somehow overlooked in
	the implementation, though - it simply picks the "most specific"
	virtualport, and uses the entire thing, with no attempt to merge in
	details from the others.

	This patch uses virNetDevVPortProfileMerge3() to combine the three
	possible virtualports into one, then uses
	virNetDevVPortProfileCheck*() to verify that the resulting virtualport
	type is appropriate for the type of network, and that all the required
	attributes for that type are present.

	An example of usage is this: assuming a <network> definitions on host
	ABC of:

	  <network>
	    <name>testA</name>
	    ...
	    <virtualport type='openvswitch'/>
	    ...
	    <portgroup name='engineering'>
	      <virtualport>
	        <parameters profileid='eng'/>
	      </virtualport>
	    </portgroup>
	    <portgroup name='sales'>
	      <virtualport>
	        <parameters profileid='sales'/>
	      </virtualport>
	    </portgroup>
	  </network>

	and the same <network> on host DEF of:

	  <network>
	    <name>testA</name>
	    ...
	    <virtualport type='802.1Qbg'>
	      <parameters typeid="1193047" typeidversion="2"/>
	    </virtualport>
	    ...
	    <portgroup name='engineering'>
	      <virtualport>
	        <parameters managerid="11"/>
	      </virtualport>
	    </portgroup>
	    <portgroup name='sales'>
	      <virtualport>
	        <parameters managerid="55"/>
	      </virtualport>
	    </portgroup>
	  </network>

	and a guest <interface> definition of:

	  <interface type='network'>
	    <source network='testA' portgroup='sales'/>
	    <virtualport>
	      <parameters instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"
	                  interfaceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"\>
	    </virtualport>
	    ...
	  </interface>

	If the guest was started on host ABC, the <virtualport> used would be:

	  <virtualport type='openvswitch'>
	    <parameters interfaceid='09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f'
	                profileid='sales'/>
	  </virtualport>

	but if that guest was started on host DEF, the <virtualport> would be:

	    <virtualport type='802.1Qbg'>
	      <parameters instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"
	                  typeid="1193047" typeidversion="2"
	                  managerid="55"/>
	    </virtualport>

	Additionally, if none of the involved <virtualport>s had a specified type
	(this includes cases where no virtualport is given at all),

2012-08-15  Laine Stump  <laine@laine.org>

	conf: support partially-specified <virtualport> in parser and formatter
	Until now, all attributes in a <virtualport> parameter list that were
	acceptable for a particular type, were also required. There were no
	optional attributes.

	One of the aims of supporting <virtualport> in libvirt's virtual
	networks and portgroups is to allow specifying the group-wide
	parameters in the network's virtualport, and merge that with the
	interface's virtualport, which will have the instance-specific info
	(i.e. the interfaceid or instanceid).

	Additionally, the guest's interface XML shouldn't need to know what
	type of network connection will be used prior to runtime - it could be
	openvswitch, 802.1Qbh, 802.1Qbg, or none of the above - but should
	still be able to specify instance-specific info just in case it turns
	out to be applicable.

	Finally, up to now, the parser for virtualport has always generated a
	random instanceid/interfaceid when appropriate, making it impossible
	to leave it blank (which is what's required for virtualports within a
	network/portprofile definition).

	This patch modifies the parser and formatter of the <virtualport>
	element in the following ways:

	* because most of the attributes in a virNetDevVPortProfile are fixed
	  size binary data with no reserved values, there is no way to embed a
	  "this value wasn't specified" sentinel into the existing data. To
	  solve this problem, the new *_specified fields in the
	  virNetDevVPortProfile object that were added in a previous patch of
	  this series are now set when the corresponding attribute is present
	  during the parse.

	* allow parsing/formatting a <virtualport> that has no type set. In
	  this case, all fields are settable, but all are also optional.

	* add a GENERATE_MISSING_DEFAULTS flag to the parser - if this flag is
	  set and an instanceid/interfaceid is expected but not provided, a
	  random one will be generated. This was previously the default
	  behavior, but is now done only for virtualports inside an
	  <interface> definition, not for those in <network> or <portgroup>.

	* add a REQUIRE_ALL_ATTRIBUTES flag to the parser - if this flag is
	  set the parser will call the new
	  virNetDevVPortProfileCheckComplete() functions at the end of the
	  parser to check for any missing attributes (based on type), and
	  return failure if anything is missing. This used to be default
	  behavior. Now it is only used for the virtualport defined inside an
	  interface's <actual> element (by the time you've figured out the
	  contents of <actual>, you should have all the necessary data to fill
	  in the entire virtualport)

	* add a REQUIRE_TYPE flag to the parser - if this flag is set, the
	  parser will return an error if the virtualport has no type
	  attribute. This also was previously the default behavior, but isn't
	  needed in the case of the virtualport for a type='network' interface
	  (i.e. the exact type isn't yet known), or the virtualport of a
	  portgroup (i.e. the portgroup just has modifiers for the network's
	  virtualport, which *does* require a type) - in those cases, the
	  check will be done at domain startup, once the final virtualport is
	  assembled (this is handled in the next patch).

	conf: simplify Buffer Indentation in virDomainNetDefFormat
	This function has several calls to increase the buffer indent by 6,
	then decrease it again, then increase, then decrease. Additionally,
	there were several printfs that had 6 spaces at the beginning of the
	line.

	virDomainActualNetDefFormat, which is called by virDomainNetDefFormat,
	had similar ugliness.

	This patch changes both functions to just increase the indent at the
	beginning, decrease it at (well, just before*) the end, and remove all
	of the occurences of 6/8 spaces at the beginning of lines.

	*The indent had to be reset before the end of the function because
	virDomainDeviceInfoFormat assumes a 0 indent and is called from many
	other places, and I didn't want to do an overhaul of every caller of
	that function. A separate patch to switch all of domain_conf.c would
	be a useful exercise, but my current goal is unrelated to that, so
	I'll leave it for another day.

	conf: make error returns from virDomainActualNetDefFormat consistent
	There was an error: label that simply did "return ret", but ret was
	defaulted to -1, and was never used other than setting it manually to
	0 just before a non-error return. Aside from this, some of the error
	return paths used "goto error" and others used "return ret".

	This patch removes ret and the error: label, and makes all error
	returns just consistently do "return -1".

2012-08-15  Laine Stump  <laine@laine.org>

	conf: move virtPortProfile out of unions in virDomainNetDef
	virtPortProfile is now used by 4 different types of network devices
	(NETWORK, BRIDGE, DIRECT, and HOSTDEV), and it's getting cumbersome to
	replicate so much code in 4 different places just because each type
	has the virtPortProfile in a slightly different place. This patch puts
	a single virtPortProfile in a common place (outside the type-specific
	union) in both virDomainNetDef and virDomainActualNetDef, and adjusts
	the parse and format code (and the few other places where it is used)
	accordingly.

	Note that when a <virtualport> element is found, the parse functions
	verify that the interface is of a type that supports one, otherwise an
	error is generated (CONFIG_UNSUPPORTED in the case of <interface>, and
	INTERNAL in the case of <actual>, since the contents of <actual> are
	always generated by libvirt itself).

2012-08-15  Laine Stump  <laine@laine.org>

	util: utility functions for virNetDevVPortProfile
	This patch adds three utility functions that operate on
	virNetDevVPortProfile objects.

	* virNetDevVPortProfileCheckComplete() - verifies that all attributes
	    required for the type of the given virtport are specified.

	* virNetDevVPortProfileCheckNoExtras() - verifies that there are no
	    attributes specified which are inappropriate for the type of the
	    given virtport.

	* virNetDevVPortProfileMerge3() - merges 3 virtports into a single,
	    newly allocated virtport. If any attributes are specified in
	    more than one of the three sources, and do not exactly match,
	    an error is logged and the function fails.

	These new functions depend on new fields in the virNetDevVPortProfile
	object that keep track of whether or not each attribute was
	specified. Since the higher level parse function doesn't yet set those
	fields, these functions are not actually usable yet (but that's okay,
	because they also aren't yet used - all of that functionality comes in
	a later patch.)

	Note that these three functions return 0 on success and -1 on
	failure. This may seem odd for the first two Check functions, since
	they could also easily return true/false, but since they actually log
	an error when the requested condition isn't met (and should result in
	a failure of the calling function), I thought 0/-1 was more
	appropriate.

	util: add openvswitch case to virNetDevVPortProfileEqual
	This function was overlooked when openvswitch support was
	added. Fortunately it's only use for update-device, which is
	relatively new and seldom-used.

	util: eliminate union in virNetDevVPortProfile
	virNetDevVPortProfile has (had) a type field that can be set to one of
	several values, and a union of several structs, one for each
	type. When a domain's interface object is of type "network", the
	domain config may not know beforehand which type of virtualport is
	going to be provided in the actual device handed down from the network
	driver at runtime, but may want to set some values in the virtualport
	that may or may not be used, depending on the type. To support this
	usage, this patch replaces the union of structs with toplevel fields
	in the struct, making it possible for all of the fields to be set at
	the same time.

	util: make return value of virUUIDFormat and virMacAddrFormat useful
	Both of these functions returned void, but it's convenient for them to
	return a const char* of the char* that is passed in. This was you can
	call the function and use the result in the same expression/arg.

	Honour current user and role in SELinux label generation
	When generating an SELinux context for a VM from the template
	"system_u:system_r:svirt_t:s0", copy the role + user from the
	current process instead of the template context. So if the
	current process is

	   unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

	then the VM context ends up as

	  unconfined_u:unconfined_r:svirt_t:s0:c386,c703

	instead of

	   system_u:system_r:svirt_t:s0:c177,c424

	Ideally the /etc/selinux/targeted/contexts/virtual_domain_context
	file would have just shown the 'svirt_t' type, and not the full
	context, but that can't be changed now for compatibility reasons.

	Fix error reporting in virSecuritySELinuxGenNewContext
	The virSecuritySELinuxGenNewContext method was not reporting any
	errors, leaving it up to the caller to report a generic error.
	In addition it could potentially trigger a strdup(NULL) in an
	OOM scenario. Move all error reporting into the
	virSecuritySELinuxGenNewContext method where accurate info
	can be provided

	Use VIR_ERR_CONFIG_UNSUPPORTED if requested security driver is disabled
	There is currently no way to distinguish the case that a requested
	security driver was disabled, from the case where no security driver
	was available. Use VIR_ERR_CONFIG_UNSUPPORTED as the error when an
	explicitly requested security driver was disabled

	Add missing domain_conf.h include in security_manager.h
	The security_manager.h header is not self-contained because it
	uses the virDomainDefPtr without first including domain_conf.h

	Add virRandom() API to generate numbers with non-power-of-2 limit
	The current virRandomBits() API is only usable if the caller wants
	a random number in the range [0, n-1) where n is a power of two.
	This adds a virRandom() API which generates a double in the
	range [0.0,1.0) with 48 bits of entropy. It then also adds a
	virRandomInt(uint32_t max) API which generates an unsigned
	in the range [0,@max)

	Fix timebomb in LIBVIRT_VERSION_INFO calculation
	The way LIBVIRT_VERSION_INFO is calculated has a timebomb that
	will cause us to accidentally break soname when we change the
	major version number to a non-zero value !

	Given CURRENT:REVISION:AGE, libtool will generate

	   libvirt.so.($CURRENT-$AGE).$AGE.$REVISION

	We set CURRENT to be MAJOR+MINOR and AGE to $MINOR, so as
	soon as MAJOR changes to non-zero, we get libvirt.so.1
	as the soname, eg  1.3.9 would create libvirt.so.1.3.9
	Looks natural but is not ABI compatible with libvirt.so.0.x.y

	The fix is to set CURRENT to always be exactly the same
	as AGE. We want to have the major version reflected in
	the so symlinks though. So then we set AGE to MAJOR*1000+MINOR
	eg, so 1.3.9 would create libvirt.so.0.1003.9 and libvirt
	2.51.3 would create libvirt.so.0.2051.3

	json: fix interface locale dependency
	libvirt creates invalid commands if wrong locale is selected. For
	example with locale that uses comma as a decimal point, JSON commands
	created with decimal numbers are invalid because comma separates the

	    $ virsh vol-create-as foo --help
	    error: command 'vol-create-as' doesn't support option --help

	This patch makes --help work in a pretty hacky way. One missing piece
	here is that --help isn't listed as an option in the actual 'help <cmd>'
	output, but maybe this can be a starting point for someone.

	mark error messages regarding operations that failed due to lack of
	support on the hypervisor or other than libvirt issues.

	The code is first used in reporting error if qemu does not support block
	IO tuning variables yielding error message:
	error: Unable to get block I/O throttle parameters
	error: Operation not supported: block_io_throttle field
	'total_bytes_sec' missing in qemu's output

	error: Unable to get block I/O throttle parameters
	error: internal error cannot read total_bytes_sec

	build: fix binary location in stap files --with-driver-modules
	libvirt_qemu_probes.stp stopped working after switching to a build
	that used --with-driver-modules. This was because the symbols listed
	int libvirt_qemu_probes.stp are no longer in $(bindir)/libvirtd, but
	are now in $(libdir)/connection-driver/libvirt_driver_qemu.so.

	This patch enhances dtrace2systemtap.pl (which generates the .stp
	files from .d files) to look for a new "module" setting in the
	comments of the .d file (similar to the existing "binary" setting),
	and to look for a --with-modules option. If the --with-modules option
	is set *and* a "module" setting is present in the .d file, the process
	name for the stap line is set to

	   $libdir/$module

	If either of these isn't true, it reverts to the old behavior.

	src/Makefile.am was also modified to add the --with-modules option
	when the build calls for it, and src/libvirt_qemu_probes.d has added a
	"module" line pointing to the correct .so file for the qemu driver.

	nwfilter: fix crash during filter define when lxc driver failed startup
	The meat of this patch is just moving the calls to
	virNWFilterRegisterCallbackDriver from each hypervisor's "register"
	function into its "initialize" function. The rest is just code
	movement to allow that, and a new virNWFilterUnRegisterCallbackDriver
	function to undo what the register function does.

	The long explanation:

	There is an array in nwfilter called callbackDrvArray that has
	pointers to a table of functions for each hypervisor driver that are
	called by nwfilter. One of those function pointers is to a function
	that will lock the hypervisor driver. Entries are added to the table
	by calling each driver's "register" function, which happens quite
	early in libvirtd's startup.

	Sometime later, each driver's "initialize" function is called. This
	function allocates a driver object and stores a pointer to it in a
	static variable that was previously initialized to NULL. (and here's
	the important part...) If the "initialize" function fails, the driver
	object is freed, and that pointer set back to NULL (but the entry in
	nwfilter's callbackDrvArray is still there).

	When the "lock the driver" function mentioned above is called, it
	assumes that the driver was successfully loaded, so it blindly tries
	to call virMutexLock on "driver->lock".

	BUT, if the initialize never happened, or if it failed, "driver" is
	NULL. And it just happens that "lock" is always the first field in
	driver so it is also NULL.

	Boom.

	To fix this, the call to virNWFilterRegisterCallbackDriver for each
	driver shouldn't be called until the end of its (*already guaranteed
	successful*) "initialize" function, not during its "register" function
	(which is currently the case). This implies that there should also be
	a virNWFilterUnregisterCallbackDriver() function that is called in a
	driver's "shutdown" function (although in practice, that function is
	currently never called).

	esx: Implement network driver
	An ESX server has one or more PhysicalNics that represent the actual
	hardware NICs. Those can be listed via the interface driver.

	A libvirt virtual network is mapped to a HostVirtualSwitch. On the
	physical side a HostVirtualSwitch can be connected to PhysicalNics.
	On the virtual side a HostVirtualSwitch has HostPortGroups that are
	mapped to libvirt virtual network's portgroups. Typically there is
	HostPortGroups named 'VM Network' that is used to connect virtual
	machines to a HostVirtualSwitch. A second HostPortGroup typically
	named 'Management Network' is used to connect the hypervisor itself
	to the HostVirtualSwitch. This one is not mapped to a libvirt virtual
	network's portgroup. There can be more HostPortGroups than those
	typical two on a HostVirtualSwitch.

	util: include stderr in log message when an external command fails
	This patch is in response to:

	  https://bugzilla.redhat.com/show_bug.cgi?id=818467

	If a caller to virCommandRun doesn't ask for the exitstatus of the
	program it's running, the virCommand functions assume that they should
	log an error message and return failure if the exit code isn't
	0. However, only the commandline and exit status are logged, while
	potentially useful information sent by the program to stderr is
	discarded.

	Fortunately, virCommandRun is already checking if the caller had asked
	for stderr to be saved and, if not, sets things up to save it in
	*cmd->errbuf. This makes it fairly simple for virCommandWait to
	include *cmd->errbuf in the error log (there are still other callers
	that don't setup errbuf, and even virCommandRun won't set it up if the
	command is being daemonized, so we have to check that it's non-zero).

	libvirtd. Set the LIBVIRT_AUTOSTART=0 environment variable to
	ensure the remote driver never tries autostart.

	Don't check the 'connect' command in virsh-all test
	The 'virsh-all' test case will invoke each virsh command with
	no args. With the 'connect' command this causes virsh to try
	to connect to the default URI, which in turn tries to spawn
	libvirtd. This is not something we want todo in the test suite,
	so skip the 'connect' command.

	Turn virDomainObjPtr into a virObjectPtr
	Switch virDomainObjPtr to use the virObject APIs for reference

	the reference count, merely a bool indicating whether the object
	still has any refs left. Checking the return value is also not
	mandatory.

	Convert public datatypes to inherit from virObject
	This converts the following public API datatypes to use the
	virObject infrastructure:

	  virConnectPtr
	  virDomainPtr
	  virDomainSnapshotPtr
	  virInterfacePtr
	  virNetworkPtr
	  virNodeDevicePtr
	  virNWFilterPtr
	  virSecretPtr
	  virStreamPtr
	  virStorageVolPtr
	  virStoragePoolPtr

	The code is significantly simplified, since the mutex in the
	virConnectPtr object now only needs to be held when accessing
	the per-connection virError object instance. All other operations
	are completely lock free.

	  public datatypes to use virObject

2012-08-07  Daniel P. Berrange  <berrange@redhat.com>

	Add a generic reference counted virObject type
	This introduces a fairly basic reference counted virObject type
	and an associated virClass type, that use atomic operations for
	ref counting.

	In a global initializer (recommended to be invoked using the
	virOnceInit API), a virClass type must be allocated for each
	object type. This requires a class name, a "dispose" callback
	which will be invoked to free memory associated with the object's
	fields, and the size in bytes of the object struct.

	eg,

	   virClassPtr  connclass = virClassNew("virConnect",
	                                        sizeof(virConnect),
	                                        virConnectDispose);

	The struct for the object, must include 'virObject' as its
	first member

	eg

	  struct _virConnect {
	    virObject object;

	    virURIPtr uri;
	  };

	The 'dispose' callback is only responsible for freeing
	fields in the object, not the object itself. eg a suitable
	impl for the above struct would be

	  void virConnectDispose(void *obj) {
	     virConnectPtr conn = obj;
	     virURIFree(conn->uri);
	  }

	There is no need to reset fields to 'NULL' or '0' in the
	dispose callback, since the entire object will be memset
	to 0, and the klass pointer & magic integer fields will
	be poisoned with 0xDEADBEEF before being free()d

	When creating an instance of an object, one needs simply
	pass the virClassPtr eg

	   virConnectPtr conn = virObjectNew(connclass);
	   if (!conn)
	      return NULL;
	   conn->uri = virURIParse("foo:///bar")

	Object references can be manipulated with

	   virObjectRef(conn)
	   virObjectUnref(conn)

	The latter returns a true value, if the object has been
	freed (ie its ref count hit zero)

	build: drop conditional use of mdns code
	Commit 1f6f723 missed a step.  At first I was worried that scrubbing
	the conditionals would lead to a runtime failure when compiled without
	avahi, but my testing makes it appear that the runtime error will only
	occur if the .conf files in /etc request mdns advertisement; and the
	old behavior was to silently ignore the request, so this is actually
	a better behavior of only failing when the config requests the
	impossible.

	Parsing xen-xm format configuration will fail if UUID is not

	virsh domxml-from-native xen-xm some-config-without-uuid
	error: internal error parsing xm config failed

	Initially I thought to skip parsing the UUID in xenParseXM() when

	conf: Remove console stream callback only when freeing console helper
	Commit ba226d334acbc49f6751b430e0c4e00f69eef6bf tried to fix crash of

	Rewrite virAtomic APIs using GLib's atomic ops code
	There are a few issues with the current virAtomic APIs

	 - They require use of a virAtomicInt struct instead of a plain
	   int type
	 - Several of the methods do not implement memory barriers
	 - The methods do not implement compiler re-ordering barriers
	 - There is no Win32 native impl

	The GLib library has a nice LGPLv2+ licensed impl of atomic
	ops that works with GCC, Win32, or pthreads.h that addresses
	all these problems. The main downside to their code is that
	the pthreads impl uses a single global mutex, instead of
	a per-variable mutex. Given that it does have a Win32 impl
	though, we don't expect anyone to seriously use the pthread.h
	impl, so this downside is not significant.

	* .gitignore: Ignore test case
	* configure.ac: Check for which atomic ops impl to use
	* src/Makefile.am: Add viratomic.c

	parallels: implement VM creation
	To create a new VM in Parallels Clud Server we should issue
	"prlctl create" command, and give path to the directory,
	where VM should be created. VM's storage will be in that
	directory later. So in this first version find out location
	of first VM's hard disk and create VM there.

2012-08-01  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: add storage driver
	Parallels Cloud Server has one serious discrepancy with libvirt:
	libvirt stores domain configuration files in one place, and storage
	files in other places (with the API of storage pools and storage volumes).
	Parallels Cloud Server stores all domain data in a single directory,
	for example, you may have domain with name fedora-15, which will be
	located in '/var/parallels/fedora-15.pvm', and it's hard disk image will be
	in '/var/parallels/fedora-15.pvm/harddisk1.hdd'.

	I've decided to create storage driver, which produces pseudo-volumes
	(xml files with volume description), and they will be 'converted' to
	real disk images after attaching to a VM.

	So if someone creates VM with one hard disk using virt-manager,
	at first virt-manager creates a new volume, and then defines a
	domain. We can lookup a volume by path in XML domain definition
	and find out location of new domain and size of its hard disk.

	Add parallelsDomainDefineXML function, it works only for existing

	It's too hard to convert libvirt's XML domain configuration into
	Parallel's one, so I've decided to compare virDomainDef structures:
	current domain definition and the one created from XML, given to
	the function. And change only different parameters.

	Currently only name, description, number of cpus, memory amount
	and video memory can be changed.

	Video device and console added, because libvirt supposes that
	VM must always have one video device, if there are some
	graphics and one console.

2012-08-01  Dmitry Guryanov  <dguryanov@parallels.com>

	parallels: add functions to list domains and get info
	Parallels driver is 'stateless', like vmware or openvz drivers.
	It collects information about domains during startup using
	command-line utility prlctl. VMs in Parallels are identified by UUIDs
	or unique names, which can be used as respective fields in
	virDomainDef structure. Currently only basic info, like
	description, virtual cpus number and memory amount, is implemented.
	Querying devices information will be added in the next patches.

	Parallels doesn't support non-persistent domains - you can't run
	a domain having only disk image, it must always be registered
	in system.

	Functions for querying domain info have been just copied from
	test driver with some changes - they extract needed data from
	previously created list of virDomainObj objects.

	Pushed without ack, under the trivial rule.

2012-08-01  Daniel P. Berrange  <berrange@redhat.com>

	Only perform symbol check against libvirt.so
	The 'check-symfile' test case was checking the contents of
	libvirt.syms against libvirt.so + all of libvirt_driver_XXX.so
	This was in fact bogus - libvirt.syms should only refer to
	stuff in libvirt.so, but it had some symbols from the various
	driver modules in it too. Now that libvirt.syms has been
	fixed, the check-symfile test can be simplified to only
	consider libvirt.so

	Don't link nwfilter or secrets driver to libvirt.so
	The nwfilter and secrets drivers are both stateful and are already
	linked directly to libvirtd. Linking them to libvirt.so is thus
	wrong, likewise exporting their symbols in libvirt.so is wrong

	Remove bogus libvirt_network.syms file
	The network driver is stateful, so it is linked directly to libvirtd,
	rather than libvirt.so. Thus there are no network symbols to be exported
	in libvirt.so, and libvirt_network.syms can be deleted

	daemon: Fix crash in virTypedParameterArrayClear
	Daemon uses the following pattern when dispatching APIs with typed
	parameters:

	    VIR_ALLOC_N(params, nparams);
	    virDomain*(dom, params, &nparams, flags);
	    virTypedParameterArrayClear(params, nparams);

	In case nparams was originally set to 0, virDomain* API would fill it
	with the number of typed parameters it can provide and we would use this
	number (rather than zero) to clear params. Because VIR_ALLOC* returns
	non-NULL pointer even if size is 0, the code would end up walking
	through random memory. If we were lucky enough and the memory contained
	7 (VIR_TYPED_PARAM_STRING) at the right place, we would try to free a
	random pointer and crash.

	Let's make sure params stays NULL when nparams is 0.

	patch sets the function to be written manually (to fix the build), but

	Improve error message in LXC startup with network is not active
	If an LXC container is using a virtual network and that network
	is not active, currently the user gets a rather unhelpful
	error message about tap device setup failure. Add an explicit
	check for whether the network is active, in exactly the same
	way as the QEMU driver

	Remove tabs from all perl files & enforce this
	The cfg.mk file rule to check for tab characters was not
	applied to perl files. Much of our Perl code is full of
	tabs as a result. Kill them, kill them all !

2012-07-30  Daniel P. Berrange  <berrange@redhat.com>

	Add handling for reboots of LXC containers
	The reboot() syscall is allowed by new kernels for LXC containers.
	The LXC controller can detect whether a reboot was requested
	(instead of a normal shutdown) by looking at the "init" process
	exit status. If a reboot was triggered, the exit status will
	record SIGHUP as the kill reason.

	The LXC controller has cleared all its capabilities, and the
	veth network devices will no longer exist at this time. Thus
	it cannot restart the container init process itself. Instead
	it emits an event which is picked up by the LXC driver in
	libvirtd. This will then re-create the container, using the
	same configuration as it was previously running with (ie it
	will not activate 'newDef').

2012-07-30  Daniel P. Berrange  <berrange@redhat.com>

	Allow CAP_SYS_REBOOT on new enough kernels
	Check whether the reboot() system call is virtualized, and if
	it is, then allow the container to keep CAP_SYS_REBOOT.

	Based on an original patch by Serge Hallyn

2012-07-30  Daniel P. Berrange  <berrange@redhat.com>

	Run an RPC protocol over the LXC controller monitor
	This defines a new RPC protocol to be used between the LXC
	controller and the libvirtd LXC driver. There is only a
	single RPC message defined thus far, an asynchronous "EXIT"
	event that is emitted just before the LXC controller process
	exits. This provides the LXC driver with details about how
	the container shutdown - normally, or abnormally (crashed),
	thus allowing the driver to emit better libvirt events.

	Emitting the event in the LXC controller requires a few
	little tricks with the RPC service. Simply calling the
	virNetServiceClientSendMessage does not work, since this
	merely queues the message for asynchronous processing.
	In addition the main event loop is no longer running at
	the point the event is emitted, so no I/O is processed.

	Thus after invoking virNetServiceClientSendMessage it is
	necessary to mark the client as being in "delayed close"
	mode. Then the event loop is run again, until the client
	completes its close - this happens only after the queued
	message has been fully transmitted. The final complexity
	is that it is not safe to run virNetServerQuit() from the
	client close callback, since that is invoked from a
	context where the server is locked. Thus a zero-second
	timer is used to trigger shutdown of the event loop,
	causing the controller to finally exit.

	* src/Makefile.am: Add rules for generating RPC protocol
	  files and dispatch methods
	* src/lxc/lxc_controller.c: Emit an RPC event immediately
	  before exiting
	* src/lxc/lxc_domain.h: Record the shutdown reason
	  given by the controller
	* src/lxc/lxc_monitor.c, src/lxc/lxc_monitor.h: Register
	  RPC program and event handler. Add callback to let
	  driver receive EXIT event.
	* src/lxc/lxc_process.c: Use monitor exit event to decide
	  what kind of domain event to emit
	* src/lxc/lxc_protocol.x: Define wire protocol for LXC
	  controller monitor.

2012-07-30  Daniel P. Berrange  <berrange@redhat.com>

	Make RPC code generator a little more flexible
	Update the gendispatch.pl script to get a little closer to
	being able to generate code for the LXC monitor, by passing
	in the struct prefix separately from the procedure prefix.
	Also allow method names using virCapitalLetters instead
	of vir_underscore_separator

	Move LXC monitor code out into separate file
	Move the code that handles the LXC monitor out of the
	lxc_process.c file and into lxc_monitor.{c,h}

	Convert the LXC driver to use virNetClient
	Update the LXC driver to use the virNetClient APIs for
	connecting to the libvirt_lxc monitor, instead of the
	low-level socket APIs. This is a step towards running
	a full RPC protocol with libvirt_lxc

	Replace use of lxcError with virReportError
	Update all LXC code to use virReportError instead of the custom
	lxcError macro

	Rename lxc_driver_t to virLXCDriver
	Rename the lxc_driver_t struct typedef to virLXCDriver to more
	closely follow normal libvirt naming conventions

	Rename all APIs in lxc_domain.c to have a virLXCDomain prefix
	For consistency all the APIs in the lxc_domain.c file should
	have a virLXCDomain prefix in their name

	Rename all APIs in lxc_process.c to have a virLXCProcess prefix
	For consistency all the APIs in the lxc_process.c file should
	have a virLXCProcess prefix in their name

	Process all pending I/O for a RPC client before checking EOF
	In the socket event handler for the RPC client we must deal
	with read/write events, before checking for EOF, otherwise
	we might close the socket before we've read & acted upon the
	last RPC messages

	Extend events demo to show close callbacks in use
	Use a driver close callback to trigger shutdown of the
	events demo program

	Update remote driver to support the connection close callbacks
	Update the remote driver to use the virNetClient close callback
	to trigger the virConnectPtr close callbacks

	Add callback to virNetClient to be invoked on connection close
	Allow detection of socket close in virNetClient via a callback
	function, triggered on any condition that causes the socket to
	be closed.

	Ensure client is marked for close in all error paths
	Currently if the keepalive timer triggers, the 'markClose'
	flag is set on the virNetClient. A controlled shutdown will
	then be performed. If an I/O error occurs during read or
	write of the connection an error is raised back to the
	caller, but the connection isn't marked for close. This
	patch ensures that all I/O error scenarios always result
	in the connection being marked for close.

	Add public API to register a callback to be invoked on connection close
	Define new virConnect{Register,Unregister}CloseCallback() public APIs
	which allows registering/unregistering a callback to be invoked when
	the connection to a hypervisor is closed. The callback is provided
	with the reason for the close, which may be 'error', 'eof', 'client'
	or 'keepalive'.

	security: Skip labeling resources when seclabel defaults to none
	If a domain is explicitly configured with <seclabel type="none"/> we
	correctly ensure that no labeling will be done by setting
	norelabel=true. However, if no seclabel element is present in domain XML
	and hypervisor is configured not to confine domains by default, we only
	set type to "none" without turning off relabeling. Thus if such a domain
	is being started, security driver wants to relabel resources with
	default label, which doesn't make any sense.

	Moreover, with SELinux security driver, the generated image label lacks
	"s0" sensitivity, which causes setfilecon() fail with EINVAL in
	enforcing mode.

	libvirt-guests: systemd host shutdown does not work
	I originally postet this into the Fedora bugzilla
	https://bugzilla.redhat.com/show_bug.cgi?id=843836

	Currently gracefully shutting down guest vms on host shutdown does not work on
	Fedora 17, the guests are killed hard on system shutdown.

	The reason is systemd considers libvirt-guests.service to be stopped when the
	system is running:

	$ systemctl status libvirt-guests.service
	libvirt-guests.service - Suspend Active Libvirt Guests
	          Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service;
	enabled)
	          Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200;
	2min 48s ago
	         Process: 1085 ExecStart=/etc/init.d/libvirt-guests start
	(code=exited, status=0/SUCCESS)
	         Control: 1150 (libvirt-guests)
	          CGroup: name=systemd:/system/libvirt-guests.service
	                  └ control
	                    ├ 1150 /bin/sh /etc/init.d/libvirt-guests stop
	                    └ 2257 sleep 1

	libvirt-guests.service is defined as type "simple" in systemd (the default).
	That means systemd will shut down the service when the start executable is
	terminated after starting is done. Systemd will not call stop again on system
	shutdown because it thinks it is already stopped.

	The solution is to define it as type "oneshot" and set the flag
	"RemainAfterExit". Then systemd will consider the service as active after
	startup and will call the stop function on host shutdown.

	Add a test case that checks there are no bogus entries in .syms
	During refactoring of code, it has proved common to forget to

	new test case validates that every symbol listed in the .syms
	file actually exists in the built ELF libraries.

	Remove accidentally commited virNetClientSetEOFNotify symbol
	The virNetClientSetEOFNotify symbol was accidentally added to

	virsh: Fix error resetting on fallback paths

	virsh: Refactor error clearing on graceful fallback paths

	returned by libvirt and updates all places where the old two-line method
	was used.

	maint: don't permit format strings without %
	Any time we have a string with no % passed through gettext, a
	translator can inject a % to cause a stack overread.  When there
	is nothing to format, it's easier to ask for a string that cannot
	be used as a formatter, by using a trivial "%s" format instead.

	In the past, we have used --disable-nls to catch some of the
	offenders, but that doesn't get run very often, and many more
	uses have crept in.  Syntax check to the rescue!

	The syntax check can catch uses such as
	virReportError(code,
	               _("split "
	                 "string"));
	by using a sed script to fold context lines into one pattern
	space before checking for a string without %.

	fixed SegFault in virauth
	No check for conn->uri being NULL in virAuthGetConfigFilePath (valid
	state) made the client segfault. This happens for example with these
	settings:
	 - no virtualbox driver installed (modifies conn->uri)
	 - no default URI set (VIRSH_DEFAULT_CONNECT_URI="",
	   LIBVIRT_DEFAULT_URI="", uri_default="")
	 - auth_sock_rw="sasl"
	 - virsh run as root

	That are unfortunately the settings with fresh Fedora 17 installation
	with VDSM.

	The check ought to be enough as conn->uri being NULL is valid in later
	code and is handled properly.

	build: regenerate .png files
	We don't expect people to have tools installed to regenerate .png
	from .fig by default.  However, since commit 5eb3df8, several
	.fig files were updated without regenerating the .png file, and
	as a result, 'make dist' ends up regenerating those five files,
	or worse, failing because of missing tools (convert from
	ImageMagick).

	Additionally, even if the tools are present, the generation of
	.png files is nondeterministic (the resulting files contain a
	timestamp), which means prior to this patch, running 'make dist'
	from two checkouts will end up producing different tarball
	contents (two 'make dist' runs will always produce different tar
	files, since tarballs also contain timestamps; but unpacking the
	tarballs and doing a recursive diff will show if the contents
	are unchanged).

	After this patch, the timestamps are now up-to-date, and 'make
	dist' no longer has anything to do for the .png files.  This gets
	us closer to the goal of two checkouts being able to produce the
	same tarball.

	Make ESX & Hyper-V code generator safe with parallel builds
	If from a clean GIT checkout 'make -j 8' is run, the ESX

	This is because there are multiple files being generated
	from one invocation of the generator script. make does not
	realize this and so invokes the generator once per file.
	This doesn't matter with serialized builds, but with
	parallel builds multiple instances of the generator get
	run at once.

	tests: reduce length of nodeinfodata test names
	Commit ddd6bef4 switched to the ustar format to fix an issue where
	'make dist' fails to create a tarball because we have files with
	relative names longer than 100 bytes by the time you include a
	'libvirt-0.9.13' prefix.  Unfortunately, even with ustar format,
	the use of 'tar -ch' tries to convert symlinks to hard links,
	also with a name too long (omitting the -h works, but automake
	automatically passes -h); such symlinks were added in commit
	6dcf98c, which resulted in 'make dist' breaking again.  The
	solution is to rename the offending symlinks to something shorter,
	by shortening the entire nodeinfodata naming scheme.

	Use a hash table for storing MCS labels
	Instead of using an O(n) efficiency linked list for storing
	MCS labels, use a hash table. Instead of having the list
	be global, put it in the SELinux driver private data struct
	to ensure uniqueness across different instances of the driver.
	This also ensures thread safety when multiple hypervisor
	drivers are used in the same libvirtd process

	Fix error handling when adding MCS labels
	When adding MCS labels, OOM was not being handled correctly.
	In addition when reserving an existing label, no check was
	made to see if it was already reserved

	Replace use of custom macros with virReportError in the Xen drivers
	Update the legacy Xen drivers to use virReportError instead of
	the statsError, virXenInotifyError, virXenStoreError,
	virXendError, xenUnifiedError, xenXMError custom macros

	Make sure xenHypervisorInit correctly reports errors
	The xenHypervisorInit method was called from two different
	locations, during initial driver registration and also while
	opening a Xen connection. The former can't report any useful
	errors to the end user/app, so remove it. To ensure thread
	safety use a VIR_ONCE_GLOBAL_INIT call to invoke
	xenHypervisorInit from the xenHypervisorOpen method.

	Ensure failure to talk to Xen hypervisor is fatal when privileged
	As per the comment, the Xen hypervisor driver is considered to
	be mandatory when running privileged. When it fails to open,
	we should thus return an error, not ignore it.

	Using virOnce for global initialization is desirable since it ensures that initialization will always take place when it is needed, and guarantees it only occurs once. The problem is that the code to setup a global initializer with proper error propagation is tedious. This introduces VIR_ONCE_GLOBAL_INIT macro to simplify this.

	Replace use of openvzError with virReportError
	Update the OpenVZ driver to use virReportError instead of
	the openvzError custom macro

	Fix Xen driver to have sensible error messages
	The Xen driver had a number of error reports which passed a
	constant string without format specifiers and was missing
	"%s". Furthermore the errors were related to failing system
	calls, but virReportSystemError was not used. So the only
	useful piece of info (the errno) was being discarded

	Move LXC process management code into separate file
	Move all the code that manages stop/start of LXC processes
	into separate lxc_process.{c,h} file to make the lxc_driver.c
	file smaller

	Move cgroup setup code out of lxc_controller.c
	Move the cgroup setup code out of the lxc_controller.c file
	and into lxc_cgroup.{c,h}. This reduces the size of the

	setup from lxc_driver.c instead of lxc_controller.c in the
	future

	Replace use of umlReportError with virReportError
	Update the UML driver to use virReportError instead of the
	umlReportError custom macro

	Add lots of internal symbols to libvirt_private.syms
	Make sure that libvirt_private.syms has all the internal symbols
	from APIs in src/rpc/*.h and src/util/cgroup.h, since the LXC
	controller/driver will shortly need them

	Reset the 'quit' flag in virNetServerRun
	To allow virNetServerRun/virNetServerQuit to be invoked multiple
	times, we must reset the 'quit' flag in virNetServerRun

	If in delay close mode for an RPC client, don't read further data
	In the delayed close mode, we're just waiting for final data to
	be written back to the client. While waiting, we should not
	bother to read more data from the client.

	Don't autostart domains when reloading config
	When sending SIGHUP to libvirtd, it will trigger the virStateDriver
	reload operation. This is intended to reload the configuration files
	for guests. For unknown historical reasons this is also triggering
	autostart of all guests. Autostart is generally expected to be
	something that happens on OS startup. Starting VMs on SIGHUP will
	violate that expectation and potentially cause dangerous scenarios
	if the admin has explicitly shutdown a misbehaving VM that has
	been marked as autostart

	Add missing deps on driver modules in libvirt RPM
	Turning on the building of driver modules in libvirt.spec.in
	means that installing 'libvirt' no longer pulls in all the
	drivers. For upgrade compatibility we need to list all drivers
	module sub-RPMs against the 'libvirt' RPM.

	Replace use of networkReportError with virReportError
	Update the linux bridge driver to use virReportError instead
	of the networkReportError custom macro

	rpc: remove trailing whitespace character in error string
	Instead of only removing the ending newline character, it is
	better to remove all of standard whitespace character for the
	sake of log format.

	One example that we have to do this is:
	After three times incorrect password input, virsh command
	virsh -c qemu://remoteserver/system will report error like:

	: Connection reset by peerey,gssapi-keyex,gssapi-with-mic,password).

	But it should be:
	Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
	: Connection reset by peer

	The reason is that we dropped the newline, but have a '\r' left.
	The terminal interprets it as "move the cursor back to the start
	of the current line", so the error string is messed up.

	nodeinfo: deal with offline cpus in a node
	Commit 80533ca forgot to think about offline cpus.  When a node
	cpu is offline, then its topology/ subdirectory is not present,
	leading to spurious error messages leaked to the user such as:

	Add a sheepdog backend for the storage driver
	This patch brings support to manage sheepdog pools and volumes to libvirt.
	It uses the "collie" command-line utility that comes with sheepdog for that.

	A sheepdog pool in libvirt maps to a sheepdog cluster.
	It needs a host and port to connect to, which in most cases
	is just going to be the default of localhost on port 7000.

	A sheepdog volume in libvirt maps to a sheepdog vdi.
	To create one specify the pool, a name and the capacity.
	Volumes can also be resized later.

	In the volume XML the vdi name has to be put into the <target><path>.
	To use the volume as a disk source for virtual machines specify
	the vdi name as "name" attribute of the <source>.
	The host and port information from the pool are specified inside the host tag.

	  <disk type='network'>
	    ...
	    <source protocol="sheepdog" name="vdi_name">
	      <host name="localhost" port="7000"/>
	    </source>
	  </disk>

	To work right this patch parses the output of collie,
	so it relies on the raw output option. There recently was a bug which caused
	size information to be reported wrong. This is fixed upstream already and
	will be in the next release.

	Mount all tmpfs filesystems with correct SELinux label
	Basically within a Secure Linux Container (virt-sandbox) we want all content
	that the process within the container can write to be labeled the same.  We
	are labeling the physical disk correctly but when we create "RAM" based file
	systems
	libvirt is not labeling them, and they are defaulting to tmpfs_t, which will
	will not allow the processes to write.  This patch labels the RAM based file
	systems correctly.

	remote: Fix locking in stream APIs
	Remote driver needs to make sure the driver lock is released before

	qemu: Fix probing for guest capabilities
	Even though qemu-kvm binaries can be used in TCG mode, libvirt would
	only detect them if /dev/kvm was available. Thus, one would need to make
	a /usr/bin/qemu symlink to be able to use TCG mode with qemu-kvm in an
	environment without KVM support.

	And even though QEMU is able to make use of KVM, libvirt would not
	advertise KVM support unless there was a qemu-kvm symlink available.

	This patch fixes both issues.

	    by the connection driver

2012-07-12  Christophe Fergeau  <cfergeau@redhat.com>

	Fix daemon auto-spawning
	Commit 32a9aac switched libvirt to use the XDG base directories
	to locate most of its data/config. In particular, the per-user socket
	for qemu:///session is now stored in the XDG runtime directory.
	This directory is located by looking at the XDG_RUNTIME_DIR environment
	variable, with a fallback to ~/.cache/libvirt if this variable is not
	set.

	When the daemon is autospawned because a client application wants
	to use qemu:///session, the daemon is ran in a clean environment
	which does not contain XDG_RUNTIME_DIR. It will create its socket
	in ~/.cache/libvirt. If the client application has XDG_RUNTIME_DIR
	set, it will not look for the socket in the fallback place, and will
	fail to connect to the autospawned daemon.

	This patch adds XDG_RUNTIME_DIR to the daemon environment before
	auto-starting it. I've done this in virNetSocketForkDaemon rather
	than in virCommandAddEnvPassCommon as I wasn't sure we want to pass
	these variables to other commands libvirt spawns. XDG_CACHE_HOME
	and XDG_CONFIG_HOME are also added to the daemon env as it makes use
	of those as well.

	Test filling of nodeinfo structure if /sys/devices/system/node does not
	exist. (Based on dump from a real machine)

	test: Add new test case for nodeinfotest
	This patch adds test data that describe a machine that has two physical
	processors that don't share same core id's on their cores. On this data
	the "virsh nodeinfo" reported that the machine had 10 cores per socket
	while the processor had only 8. (Before fixing nodeinfo gathering code).

	nodeinfo: Fix gathering of nodeinfo data structure
	This patch changes the way data to fill the nodeinfo structure are
	gathered. We've gathere the test data by iterating processors an sockets
	separately from nodes. The reported data was based solely on information
	about core id. Problems arise when eg cores in mulit-processor machines
	don't have same id's on both processors or maybe one physical processor
	contains more NUMA nodes.

	This patch changes the approach how we detect processors and nodes. Now
	we start at enumerating nodes and for each node processors, sockets and
	threads are enumerated separately. This approach provides acurate data
	that comply to docs about the nodeinfo structure. This also enables to
	get rid of hacks: see commits 10d9038b744a69c8d4bd29c2e8c012a097481586,
	ac9dd4a676f21b5e3ca6dbe0526f2a6709072beb. (Those changes in nodeinfo.c
	are efectively reverted by this patch).

	This patch also changes output of one of the tests, as the processor
	topology is now acquired more precisely.

	qemu: Extended qemuDomainAssignAddresses to be callable from everywhere.
	This is in preparation of the enablement of s390 guests with virtio devices.

	The assignment of device addresses happens in different places, i.e. the
	qemu driver and process modules as well as in the unit tests in slightly
	different flavors. Currently, these are PPC spapr-vio and PCI
	devices, virtio-s390 (not PCI based) will follow.

	By optionally passing to qemuDomainAssignAddresses the domain
	object and the capabilities it is now possible to call the function
	from most of the places (except for hotplug) where address assignment
	is done.

	openvz: Handle domain obj hash map errors
	This makes the driver fail with a clear error message in case of UUID
	collisions (for example if somebody copied a container configuration
	without updating the UUID) and also raises an error on other hash map
	failures.

	OpenVZ itself doesn't complain about duplicate UUIDs since this
	parameter is only used by libvirt.

	Fix /domain/features setting in qemuParseCommandLine
	Commit 5e6ce1 moved down detection of the ACPI feature in
	qemuParseCommandLine. However, when ACPI is detected, it clears
	all feature flags in def->features to only set ACPI. This used to
	be fine because this was the first place were def->features was set,
	but after the move this is no longer necessarily true because this
	block comes before the ACPI check:

	if (strstr(def->emulator, "kvm")) {
	    def->virtType = VIR_DOMAIN_VIRT_KVM;
	    def->features |= (1 << VIR_DOMAIN_FEATURE_PAE);
	}

	Since def is allocated in qemuParseCommandLine using VIR_ALLOC, we
	can always use |= when modifying def->features

	Commit 122fa379de44a2fd0a6d5fbcb634535d647ada17 introduces option to

	Switch to using virNetServer APIs for monitor socket
	In preparation for introducing a full RPC protocol for

	for the monitor connection

	Move loop device setup code into virfile.{c,h}
	While it is not currently used elsewhere in libvirt, the code
	for finding a free loop device & associating a file with it
	is not LXC specific. Move it into the viffile.{c,h} file where
	potentially shared code is more commonly kept.

	Move the monitor FDs into the virLXCControllerPtr object
	removing the need for the 'struct lxcMonitor' object

	Move /dev/pts setup out of virLXCControllerRun
	The virLXCControllerRun method is getting a little too large,
	and about 50% of its code is related to setting up a /dev/pts
	mount. Move the latter out into a dedicated method

	Move security manager into virLXCControllerPtr object

	Move the veth device name state into the virLXCControllerPtr
	object and stop passing it around. Also use size_t instead

	Introduce a virLXCControllerPtr object to hold LXC controller state
	The LXC controller code is having to pass around an ever increasing
	number of parameters between methods. To make the code more managable
	introduce a virLXCControllerPtr to hold all this state, starting with
	the container name and virDomainDefPtr object

	Avoid build shared source files again for libvirt_lxc
	Currently the build of libvirt_lxc will cause recompilation
	of all sources under src/util, src/conf, src/security and
	more. Switch the libvirt_lxc process to link against the
	libtool convenience libraries that are already built as
	part of the main libvirt.os & libvirtd build process

	Allow RPC server to run single threaded
	Refactor the RPC server dispatcher code so that if 'max_workers==0'

	The callback that is invoked when a new RPC client is
	initialized does not have any opaque parameter. Add
	one so that custom data can be passed into the callback

	Fix vm's outbound traffic control problem
	Hello,

	This is a patch to fix vm's outbound traffic control problem.

	Currently, vm's outbound traffic control by libvirt doesn't go well.
	This problem was previously discussed at libvir-list ML, however
	it seems that there isn't still any answer to the problem.
	http://www.redhat.com/archives/libvir-list/2011-August/msg00333.html

	I measured Guest(with virtio-net) to Host TCP throughput with the
	command "netperf -H".
	Here are the outbound QoS parameters and the results.

	outbound average rate[kilobytes/s] : Guest to Host throughput[Mbit/s]
	======================================================================
	1024  (8Mbit/s)                    : 4.56
	2048  (16Mbit/s)                   : 3.29
	4096  (32Mbit/s)                   : 3.35
	8192  (64Mbit/s)                   : 3.95
	16384 (128Mbit/s)                  : 4.08
	32768 (256Mbit/s)                  : 3.94
	65536 (512Mbit/s)                  : 3.23

	The outbound traffic goes down unreasonably and is even not controled.

	The cause of this problem is too large mtu value in "tc filter" command run by
	libvirt. The command uses burst value to set mtu and the burst is equal to
	average rate value if it's not set. This value is too large. For example
	if the average rate is set to 1024 kilobytes/s, the mtu value is set to 1024
	kilobytes. That's too large compared to the size of network packets.
	Here libvirt applies tc ingress filter to Host's vnet(tun) device.
	Tc ingress filter is implemented with TBF(Token Buckets Filter) algorithm. TBF
	uses mtu value to calculate the amount of token consumed by each packet. With too
	large mtu value, the token consumption rate is set too large. This leads to
	token starvation and deterioration of TCP throughput.

	Then, should we use the default mtu value 2 kilobytes?
	The anser is No, because Guest with virtio-net device uses 65536 bytes
	as mtu to transmit packets to Host, and the tc filter with the default mtu
	value 2k drops packets whose size is larger than 2k. So, the most packets
	is droped and again leads to deterioration of TCP throughput.

	The appropriate mtu value is 65536 bytes which is equal to the maximum value
	of network interface device defined in <linux/netdevice.h>. The value is
	not so large that it causes token starvation and not so small that it
	drops most packets.
	Therefore this patch set the mtu value to 64kb(== 65535 bytes).

	Again, here are the outbound QoS parameters and the TCP throughput with
	the libvirt patched.

	outbound average rate[kilobytes/s] : Guest to Host throughput[Mbit/s]
	======================================================================
	1024  (8Mbit/s)                    : 8.22
	2048  (16Mbit/s)                   : 16.42
	4096  (32Mbit/s)                   : 32.93
	8192  (64Mbit/s)                   : 66.85
	16384 (128Mbit/s)                  : 133.88
	32768 (256Mbit/s)                  : 271.01
	65536 (512Mbit/s)                  : 547.32

	The outbound traffic conforms to the given limit.

	Thank you,

	vbox: Add support for virConnectListAllDomains()

	virConnectDomainEventRegisterAny() takes a domain as an argument.
	So it should be possible to register the same event (be it

	That is, we need to take domain into account when searching for
	duplicate event being already registered.

	S390: Added sysinfo for host on s390(x).
	In order to retrieve some sysinfo data we need to parse /proc/sysinfo and
	/proc/cpuinfo.

2012-06-25  Viktor Mihajlovski  <mihajlov@linux.vnet.ibm.com>

	S390: Fixed core identification for s390
	For the s390x architecture the sysfs core_id alone is not unique. As a
	result it can happen that libvirt thinks there are less host CPUs available
	than really present.
	Currently, a logical CPU is equivalent to a core for s390x. We therefore
	produce a fake core id from the CPU number.

	S390: Override QEMU_CAPS_NO_ACPI for s390x
	Starting a KVM guest on s390 fails immediately. This is because
	"qemu --help" reports -no-acpi even for the s390(x) architecture but
	-no-acpi isn't supported there.
	Workaround is to remove QEMU_CAPS_NO_ACPI from the capability set
	after the version/capability extraction.

	storage backend rbd: Do not prefix rbd: on volume names.
	We used to prefix 'rbd:' to volume names, this is not necessary.

	Qemu takes RBD devices in this way, like: qemu -drive rbd:pool/image

	When attaching a network disk like RBD to a guest we however do not use this prefix.

	Currently you can't map a RBD volume name directly to a domain without removing the prefix.

	storage: Introduce --inactive for pool-dumpxml
	Storage is one of the last domains in libvirt where we don't fully
	utilize inactive and live XML. Okay, it might be because we don't
	have support for that. So implement such support. However, we need
	to fallback when talking to old daemon which doesn't support this
	new flag called VIR_STORAGE_XML_INACTIVE.

	storage: Switch to new def on pool-destroy
	Currently, we share the idea of old & new def with domains. Users can
	*-edit an object (domain, pool) which spawns a new internal
	representation for them. This is referenced via
	{domainObj,poolObj}->newDef [compared to ->def]. However, for pool we
	were never overwriting def with newDef. This must be done on
	pool-destroy (like we do analogically in domain detroy).

	sanlock: Properly indent
	One of latest patches (0fce94fe) didn't properly indented #define
	making syntax-check fail.

	Support bind mounting host files, as well as directories in LXC
	Currently libvirt-lxc checks to see if the destination exists and is a
	directory.  If it is not a directory then the mount fails.  Since
	libvirt-lxc can bind mount files on an inode, this patch is needed to
	allow us to bind mount files on files.  Currently we want to bind mount
	on top of /etc/machine-id, and /etc/adjtime

	If the destination of the mount point does not exists, it checks if the
	src is a directory and then attempts to create a directory, otherwise it
	creates an empty file for the destination.  The code will then bind mount
	over the destination.

	Allow NOCONFIGURE=1 to make autogen.sh skip ./configure

	Fix unused parameters / functions in virsh on Win32

	winsock2.h must always be included before windows.h
	Some GNULIB headers (eg unistd.h) will often need to include
	winsock2.h for various symbols. There is a rule that winsock2.h
	must be included before windows.h. This means that any file
	which does

	  #ifdef WIN32
	  #include <windows.h>
	  #endif
	  #include <unistd.h>

	is potentially broken. A simple rule is that /all/ includes of

	regardless of whether unistd.h is used currently

	Switch automated builds to use Mingw64 toolchain instead of Mingw32
	The Mingw32 toolchain is broadly obsoleted by the Mingw64 toolchain.
	The latter has been adopted by Fedora 17 and newer. Maintaining a
	RPM spec for Mingw32 is a needless burden, so switch to a Mingw64
	RPM spec (which provides 32 & 64 bit builds).

	Fix deadlock on libvirtd shutdown
	When shutting down libvirtd, the virNetServer shutdown can deadlock
	if there are in-flight jobs being handled by virNetServerHandleJob().
	virNetServerFree() will acquire the virNetServer lock and call
	virThreadPoolFree() to terminate the workers, waiting for the workers
	to finish.  But in-flight workers will attempt to acquire the
	virNetServer lock, resulting in deadlock.

	Fix the deadlock by unlocking the virNetServer lock before calling
	virThreadPoolFree().  This is safe since the virNetServerPtr object
	is ref-counted and only decrementing the ref count needs to be
	protected.  Additionally, there is no need to re-acquire the lock
	after virThreadPoolFree() completes as all the workers have
	terminated.

	virsh: add support for virConnectListAllDomains and clean up cmdList
	This patch makes use of the newly added api virConnectListAllDomains()
	to list domains in virsh.

	Virsh now represents lists of domains using an internal structure
	vshDomainList. This structure contains the virDomainPtr list as provided
	by virConnectListAllDomains() and the count of domains in the list.

	For backwards compatibility, the function vshDomainListCollect was added
	that tries to enumerate the domains using the new API and if the API is
	not supported falls back to the older approach with the two list
	functions.  The helper function also simulates filtering by all
	currently supported flags added with virConnectListAllDomains().

	This patch also cleans up the "list" command handler to use the new
	helpers and adds new command line flags to make use of filtering.

	storage: Set the perms if the pool target already exists for fs pools
	The comment says:

	/* Now create the final dir in the path with the uid/gid/mode
	 * requested in the config. If the dir already exists, just set
	 * the perms.
	 */

	However, virDirCreate is only invoked if the target path doesn't
	exist yet (which is opposite with the comment), or the uid from
	the config is not -1 (I don't understand why, think it's just
	another mistake). And the result is the perms of the pool won't
	be changed if one tries to build the pool with different perms
	again.

	Besides these logic error fix, if no uid and gid are specified in
	the config, the practical used uid, gid are reflected.

	snapshot: require existence before returning success
	Blindly returning success is misleading if the object no longer

	effect prior to getting at the real piece of information being
	queried.

	* src/esx/esx_driver.c (esxDomainIsUpdated, esxDomainIsPersistent):

	snapshot: expose new flags in virsh
	Previously, to get the name of all snapshots with children, it was
	necessary to get the name of all snapshots and then remove the
	name of leaf snapshots.  This is racy, and somewhat inefficient
	compared to planned API additions.  We can emulate --no-metadata on
	0.9.5-0.9.12, but for now, there is no emulation of --no-leaves.

	* tools/virsh.c (cmdSnapshotList): Add new options --no-leaves and

	* tools/virsh.pod (snapshot-list): Document them.

2012-06-20  Eric Blake  <eblake@redhat.com>

	snapshot: add additional filters when getting lists
	It turns out that one-bit filtering makes it hard to select the inverse
	set, so it is easier to provide filtering groups.  For back-compat,
	omitting all bits within a group means the group is not used for
	filtering, and by definition of a group (each snapshot matches exactly
	one bit within the group, and the set of bits in the group covers all
	snapshots), selecting all bits also makes the group useless.

	Unfortunately, virDomainSnapshotListChildren defined the bit
	VIR_DOMAIN_SNAPSHOT_LIST_DESCENDANTS as an expansion rather than a
	filter, so we cannot make it part of a filter group, so that bit
	(and its counterpart VIR_DOMAIN_SNAPSHOT_LIST_ROOTS for
	virDomainSnapshotList) remains a single control bit.

	* include/libvirt/libvirt.h.in (virDomainSnapshotListFlags): Add a
	couple more flags.
	* src/libvirt.c (virDomainSnapshotNum)
	(virDomainSnapshotNumChildren): Document them.

	convenience macros.
	* src/conf/domain_conf.c (virDomainSnapshotObjListCopyNames)

	snapshot: use metaroot node to simplify management
	This idea was first suggested by Daniel Veillard here:
	https://www.redhat.com/archives/libvir-list/2011-October/msg00353.html

	Now that I am about to add more complexity to snapshot listing, it
	makes sense to avoid code duplication and special casing for domain
	listing (all snapshots) vs. snapshot listing (descendants); adding
	a metaroot reduces the number of code lines by having the domain
	listing turn into a descendant listing of the metaroot.

	Note that this has one minor pessimization - if we are going to list
	ALL snapshots without filtering, then virHashForeach is more efficient
	than recursing through the child relationships; restoring that minor
	optimization will occur in the next patch.

	remote: implement remote protocol for virConnectListAllDomains()
	This patch wires up the RPC protocol handlers for
	virConnectListAllDomains(). The RPC generator has no support for the way
	how virConnectListAllDomains() returns the results so the handler code
	had to be done manually.

	The new api is handled by REMOTE_PROC_CONNECT_LIST_ALL_DOMAINS, with
	number 273 and marked with high priority.

	python: add API exports for virConnectListAllDomains()
	This patch adds export of the new API function

	virConnect object now has method "listAllDomains" that takes only the
	flags parameter and returns a python list of virDomain object
	corresponding to virDomainPtrs returned by the underlying api.

	The implementation is done manually as the generator does not support
	wrapping list of virDomainPtrs into virDomain objects.

	lib: Add public api to enable atomic listing of guest
	This patch adds a new public api that lists domains. The new approach is
	different from those used before. There are key points to this:

	1) The list is acquired atomically and contains both active and inactive
	domains (guests). This eliminates the need to call two different list
	APIs, where the state might change in between the calls.

	2) The returned list consists of virDomainPtrs instead of names or ID's
	that have to be converted to virDomainPtrs anyways using separate calls
	for each one of them. This is more convenient and saves hypervisor calls.

	3) The returned list is auto-allocated. This saves a lot of hassle for
	the users.

	4) Built in support for filtering. The API call supports various
	filtering flags that modify the output list according to user needs.

	Available filter groups:
	    Domain status:
	    VIR_CONNECT_LIST_DOMAINS_ACTIVE, VIR_CONNECT_LIST_DOMAINS_INACTIVE

	    Domain persistence:
	    VIR_CONNECT_LIST_DOMAINS_PERSISTENT,
	    VIR_CONNECT_LIST_DOMAINS_TRANSIENT

	    Domain state:
	    VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED,
	    VIR_CONNECT_LIST_DOMAINS_SHUTOFF, VIR_CONNECT_LIST_DOMAINS_OTHER

	    Existence of managed save image:
	    VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE,
	    VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE

	    Auto-start option:
	    VIR_CONNECT_LIST_DOMAINS_AUTOSTART,
	    VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART

	    Existence of snapshot:
	    VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT,
	    VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT

	5) The python binding returns a list of domain objects that is very neat
	to work with.

	The only problem with this approach is no support from code generators
	so both RPC code and python bindings had to be written manually.

	virsh: Report name from edited object
	There is a little easter egg in virsh: one can easily clone
	an object (domain, network, ...). Just 'virsh edit' change the name
	and remove <uuid>. And then, in the end when reporting success
	the new name was printed out.
	However, with recent edit rewrite we lost the final part and are
	still printing the original name out.

	virsh: Honor reedit opts printing to a function
	When printing reedit options we make stdin raw. However,
	this results in stdout being raw as well. Therefore we need
	to return carriage when doing new line. Unfortunately,
	'\r' cannot be part of internationalized messages hence
	we must move them to formatting string which then in turn
	become huge and disarranged. To solve this, a new function
	is introduced which takes variable string arguments and
	prepend each with "\r\n" just before printing.

	network: fully support/use VIR_NETWORK_XML_INACTIVE flag
	commit 52d064f42dbc857f4096dc60c0335395ffac73aa added
	VIR_NETWORK_XML_INACTIVE in order to allow suppressing the
	auto-generated list of VFs in network definitions, and a --inactive
	flag to virsh net-dumpxml to take advantage of the flag. However, it
	missed out on two opportunities:

	1) Use INACTIVE to get the current config of the network as it
	   exists on disk, rather than the currently active config.

	2) Add INACTIVE to the flags used for the virsh net-edit command, so
	   that it won't include the forward-pool interfaces that were
	   autogenerated, and so that a re-edit of the network prior to
	   restarting it will show any other edits made since the last restart
	   of the network. (prior to this patch, if you edited a network a 2nd
	   time without restarting, all of the previous edits would magically
	   disappear).

	In order to fit with the new #define-based generic edit function in
	virsh.c, a new function vshNetworkGetXMLDesc() was added. This
	function first tries to call virNetworkGetXMLDesc with the INACTIVE
	flag added, then retries without if the first attempt fails (in the
	manner expected when the server doesn't support it).

	Add some missing hook functions
	A core use case of the hook scripts is to be able to do things
	to a guest's network configuration. It is possible to hook into
	the 'start' operation for a QEMU guest which runs just before
	the guest is started. The TAP devices will exist at this point,
	but the QEMU process will not. It can be desirable to have a
	'started' hook too, which runs once QEMU has started.

	If libvirtd is restarted it will re-populate firewall rules,
	but there is no QEMU hook to trigger for existing domains.
	This is solved with a 'reconnect' hook.

	Finally, if attaching to an external QEMU process there needs
	to be an 'attach' hook script.

	This all also applies to the LXC driver

	client rpc: Send keepalive requests from IO event loop
	In addition to keepalive responses, we also need to send keepalive
	requests from client IO loop to properly detect dead connection in case
	a libvirt API is called from the main loop, which prevents any timers to
	be called.

	server rpc: Remove APIs for manipulating filters on locked client
	We don't need to add or remove filters when client object is already
	locked anymore. There's no reason to keep the *Locked variants of those
	APIs.

	rpc: Remove unused parameter in virKeepAliveStopInternal
	The previous commit removed the only usage of ``all'' parameter in
	virKeepAliveStopInternal, which was actually the only reason for having
	virKeepAliveStopInternal. This effectively reverts most of commit
	6446a9e20cc65561ce6061742baf35a3a63d5ba1.

	rpc: Do not use timer for sending keepalive responses
	When a libvirt API is called from the main event loop (which seems to be
	common in event-based glib apps), the client IO loop would properly
	handle keepalive requests sent by a server but will not actually send
	them because the main event loop is blocked with the API. This patch
	gets rid of response timer and the thread which is processing keepalive
	requests is also responsible for queueing responses for delivery.

	client rpc: Separate call creation from running IO loop
	This makes it possible to create and queue new calls while we are
	running IO loop.

	rpc: Add APIs for direct triggering of keepalive timer
	Add virKeepAliveTimeout and virKeepAliveTrigger APIs that can be used to
	set poll timeouts and trigger keepalive timer. virKeepAliveTrigger
	checks if it is called to early and does nothing in that case.

	rpc: Refactor keepalive timer code
	The code that needs to be run every keepalive interval of inactivity was
	only called from a timer and thus from the main event loop. We will need
	to call the code directly from another place.

	client rpc: Drop unused return value of virNetClientSendNonBlock
	As we never drop non-blocking calls, the return value that used to
	indicate a call was dropped is no longer needed.

	client rpc: Just queue non-blocking call if another thread has the buck
	As non-blocking calls are no longer dropped, we don't really need to
	care that much about their fate and wait for the thread with the buck
	to process them. If another thread has the buck, we can just push a
	non-blocking call to the queue and be done with it.

2012-06-13  Jiri Denemark  <jdenemar@redhat.com>

	client rpc: Don't drop non-blocking calls
	So far, we were dropping non-blocking calls whenever sending them would
	block. In case a client is sending lots of stream calls (which are not
	supposed to generate any reply), the assumption that having other calls
	in a queue is sufficient to get a reply from the server doesn't work. I
	tried to fix this in b1e374a7ac56927cfe62435179bf0bba1e08b372 but
	failed and reverted that commit.

	With this patch, non-blocking calls are never dropped (unless the

	client rpc: Use event loop for writing
	Normally, when every call has a thread associated with it, the thread
	may get the buck and be in charge of sending all calls until its own
	call is done. When we introduced non-blocking calls, we had to add
	special handling of new non-blocking calls. This patch uses event loop
	to send data if there is no thread to get the buck so that any
	non-blocking calls left in the queue are properly sent without having to
	handle them specially. It also avoids adding even more cruft to client
	IO loop in the following patches.

	With this change in, non-blocking calls may see unpredictable delays in
	delivery when the client has no event loop registered. However, the only
	non-blocking calls we have are keepalives and we already require event
	loop for them, which makes this a non-issue until someone introduces new
	non-blocking calls.

	build: fix 'make dist' on virgin checkout
	'make dist' was depending on *protocol-structs files, which are
	stored in git but in turn depended on generated files.  We still
	want to ship the protocol-structs files, but by renaming the
	tests to something not matching a file name, we separate 'make
	check' (which depends on the generated file) from 'make dist'
	(which only depends on the git files).  After all, the tarball
	should never depend on a generated file not stored in git.

	I found one more case of a git file depending on a generated
	file, in a bogus virkeycode.c listing; but at least this one
	had no associated rules so it never broke 'make dist'.

	Reported by Wen Congyang.  Latent bug has been present since
	commit 62dee6f, but only recently exposed by commit 7bff56a.

	qemu: Don't overwrite security labels
	Currently, if qemuProcessStart fail at some point, e.g. because
	domain being started wants a PCI/USB device already assigned to
	a different domain, we jump to cleanup label where qemuProcessStop
	is performed. This unconditionally calls virSecurityManagerRestoreAllLabel
	which is wrong because the other domain is still using those devices.

	However, once we successfully label all devices/paths in

	on failure - that is - we have to virSecurityManagerRestoreAllLabel.

	snapshot: new query APIs
	Right now, starting from just a virDomainSnapshotPtr, and wanting to
	know if it is the current snapshot for its respective domain, you have
	to use virDomainSnapshotGetDomain(), then virDomainSnapshotCurrent(),
	then compare the two names returned by virDomainSnapshotGetName().
	It is a bit easier if we can directly query this information from the
	snapshot itself.

	Right now, it is possible to filter a snapshot listing based on
	whether snapshots have metadata that would prevent domain deletion,
	but the only way to learn if an individual snapshot has metadata is
	to see if that snapshot appears in the list returned by a listing.
	Additionally, I hope to expand the qemu driver in a future patch to
	use qemu-img to reconstruct snapshot XML corresponding to internal
	qcow2 snapshot names not otherwise tracked by libvirt (in part, so
	that libvirt can guarantee that new snapshots are not created with
	a name that would silently corrupt the existing portion of the qcow2
	file); if I ever get that in, then it would no longer be an all-or-none
	decision on whether snapshots have metadata, and becomes all the more
	important to be able to directly determine that information from a
	particular snapshot.

	Other query functions (such as virDomainIsActive) do not have a flags
	argument, but since virDomainHasCurrentSnapshot takes a flags argument,
	I figured it was safer to provide a flags argument here as well.

	virsh: make tree listing more flexible
	Requiring the user to pass in parallel arrays of names and parents

	to use callbacks, we isolate the layout to be independent of the

	open up the potential for bad code to dereference a stale pointer,

	command: avoid potential deadlock on handshake
	There is a theoretical problem of an extreme bug where we can get
	into deadlock due to command handshaking.  Thanks to a pair of pipes,
	we have a situation where the parent thinks the child reported an
	error and is waiting for a message from the child to explain the
	error; but at the same time the child thinks it reported success
	and is waiting for the parent to acknowledge the success; so both
	processes are now blocked.

	Thankfully, I don't think this deadlock is possible without at
	least one other bug in the code, but I did see exactly that sort
	of situation prior to commit da831af - I saw a backtrace where a
	double close bug in the parent caused the parent to read from the
	wrong fd and assume the child failed, even though the child really
	sent success.

	This potential deadlock is not quite like commit 858c247 (a deadlock
	due to multiple readers on one pipe preventing a write from completing),
	although the solution is similar - always close unused pipe fds before
	blocking, rather than after.

	* src/util/command.c (virCommandHandshakeWait): Close unused fds
	sooner.

	This patch fixes that and also changes the other result (when machine

	rpc: Size up RPC limits
	Since we are allocating RPC buffer dynamically, we can increase limits
	for max. size of RPC message and RPC string. This is needed to cover
	some corner cases where libvirt is run on such huge machines that their
	capabilities XML is 4 times bigger than our current limit. This leaves
	users with inability to even connect.

	rpc: Switch to dynamically allocated message buffer
	Currently, we are allocating buffer for RPC messages statically.
	This is not such pain when RPC limits are small. However, if we want
	ever to increase those limits, we need to allocate buffer dynamically,
	based on RPC message len (= the first 4 bytes). Therefore we will
	decrease our mem usage in most cases and still be flexible enough in
	corner cases.

	build: fix 'make distcheck' issues
	We had a distributed file (remote_protocol.h, which in turn was
	a prereq to remote_driver.c) depending on a generated file
	(libvirt_probes.h), which is a no-no for a VPATH build from a
	read-only source tree (no wonder 'make distcheck' tests precisely
	that situation):

	     File `libvirt_driver_remote.la' does not exist.
	       File `libvirt_driver_remote_la-remote_driver.lo' does not exist.
	             Prerequisite `libvirt_probes.h' is newer than target `../../src/remote/remote_protocol.h'.
	            Must remake target `../../src/remote/remote_protocol.h'.

	cannot create ../../src/remote/remote_protocol.h: Permission denied at ../../src/rpc/genprotocol.pl line 31.
	make[3]: *** [../../src/remote/remote_protocol.h] Error 13

	Rather than making distributed .c files depend on generated files, we
	really want to ensure that compilation into .lo files is not attempted
	until the generated files are present, done by this patch.  Since there
	were two different sets of conditionally generated files that both
	feed the .lo file, I had to introduce a new variable REMOTE_DRIVER_PREREQS
	to keep automake happy.

	After that fix, the next issue was that make treats './foo' and 'foo'
	differently in determining whether an implicit %foo rule is applicable,
	with the result that locking/qemu-sanlock.conf wasn't properly being
	built at the right times.  Also, the output for using the .aug test
	files was a bit verbose.

	After fixing the src directory, the next error is related to the docs

	regenerate files that are already present:

	Fix for parallel port passthrough for QEMU
	I came across a bug that the command line generated for passthrough
	of the host parallel port /dev/parport0 by libvirt for QEMU is incorrect.

	It currently produces:
	-chardev tty,id=charparallel0,path=/dev/parport0
	-device isa-parallel,chardev=charparallel0,id=parallel0

	The first parameter is "tty". It sould be "parport".

	If I launch qemu with -chardev parport,... it works as expected.

	I have already filled a bug report (
	https://bugzilla.redhat.com/show_bug.cgi?id=823879 ), the topic was
	already on the list some months ago:

	command: avoid deadlock on EPIPE situation
	It is possible to deadlock libvirt by having a domain with XML
	longer than PIPE_BUF, and by writing a hook script that closes
	stdin early.  This is because libvirt was keeping a copy of the
	child's stdin read fd open, which means the write fd in the
	parent will never see EPIPE (remember, libvirt should always be
	run with SIGPIPE ignored, so we should never get a SIGPIPE signal).
	Since there is no error, libvirt blocks waiting for a write to
	complete, even though the only reader is also libvirt.  The
	solution is to ensure that only the child can act as a reader
	before the parent does any writes; and then dealing with the
	fallout of dealing with EPIPE.

	Thankfully, this is not a security hole - since the only way to
	trigger the deadlock is to install a custom hook script, anyone
	that already has privileges to install a hook script already has
	privileges to do any number of other equally disruptive things
	to libvirt; it would only be a security hole if an unprivileged
	user could install a hook script to DoS a privileged user.

	* src/util/command.c (virCommandRun): Close parent's copy of child
	read fd earlier.
	(virCommandProcessIO): Don't let EPIPE be fatal; the child may
	be done parsing input.
	* tests/commandhelper.c (main): Set up a SIGPIPE situation.
	* tests/commandtest.c (test20): Trigger it.
	* tests/commanddata/test20.log: New file.

	virsh: Allow users to reedit rejected XML
	If users *-edit but make a mistake in XML all changes are

	virsh: Switch from generated cmd*Edit commands to nongenerated
	Currently, we either generate some cmd*Edit commands (cmdPoolEdit

	(e.g. cmdInterfaceEdit, cmdNWFilterEdit, etc.). This fact makes
	it harder to implement any new feature to our editing system.
	Therefore switch to new implementation - define macros to:
	- dump XML (EDIT_GET_XML)
	- take an action if XML wasn't changed,
	  usually just vshPrint() (EDIT_NOT_CHANGED)
	- define new object (EDIT_DEFINE) - the edited XML is in @doc_edited
	- free object defined by EDIT_DEFINE (EDIT_FREE)
	and #include "virsh-edit.c"

	nwfilter: Add multiple IP address support to DHCP snooping
	With support for multiple IP addresses per interface in place, this patch
	now adds support for multiple IP addresses per interface for the DHCP
	snooping code.


	Testing:

	Since the infrastructure I tested this with does not provide multiple IP
	addresses per MAC address (anymore), I either had to plug the VM's interface
	from the virtual bride connected directly to the infrastructure to virbr0
	to get a 2nd IP address from dnsmasq (kill and run dhclient inside the VM)
	or changed the lease file  (/var/run/libvirt/network/nwfilter.leases) and
	restart libvirtd to have a 2nd IP address on an existing interface.
	Note that dnsmasq can take a lease timeout parameter as part of the --dhcp-range
	command line parameter, so that timeouts can be tested that way
	(--dhcp-range 192.168.122.2,192.168.122.254,120). So, terminating and restarting
	dnsmasq with that parameter is another choice to watch an IP address disappear
	after 120 seconds.

	Regards,
	   Stefan

	nwfilter: move code for IP address map into separate file
	The goal of this patch is to prepare for support for multiple IP
	addresses per interface in the DHCP snooping code.

	Move the code for the IP address map that maps interface names to
	IP addresses into their own file. Rename the functions on the way
	but otherwise leave the code as-is. Initialize this new layer
	separately before dependent layers (iplearning, dhcpsnooping)
	and shut it down after them.

2012-06-02  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	nwfilter: add DHCP snooping
	This patch adds DHCP snooping support to libvirt. The learning method for
	IP addresses is specified by setting the "CTRL_IP_LEARNING" variable to one of
	"any" [default] (existing IP learning code), "none" (static only addresses)
	or "dhcp" (DHCP snooping).

	Active leases are saved in a lease file and reloaded on restart or HUP.

	The following interface XML activates and uses the DHCP snooping:

	    <interface type='bridge'>
	      <source bridge='virbr0'/>
	      <filterref filter='clean-traffic'>
	        <parameter name='CTRL_IP_LEARNING' value='dhcp'/>
	      </filterref>
	    </interface>

	All filters containing the variable 'IP' are automatically adjusted when
	the VM receives an IP address via DHCP. However, multiple IP addresses per
	interface are silently ignored in this patch, thus only supporting one IP
	address per interface. Multiple IP address support is added in a later
	patch in this series.

	qemu: move -name arg to be 1st in "ps x" output
	Currently, monitoring QEMU virtual machines with standard Unix
	sysadmin tools is harder than it has to be. The QEMU command line is
	often miles long and mostly redundant, it's hard to tell which process
	is which.

	This patch reorders the QEMU -name argument to be the first, so it's
	immediately visible in "ps x", htop and "atop -c" output.

	qemu: fix netdev alias name assignment wrt type='hostdev'
	This patch resolves:

	   https://bugzilla.redhat.com/show_bug.cgi?id=827519

	The problem is that an interface with type='hostdev' will have an
	alias of the form "hostdev%d", while the function that looks through
	existing netdevs to determine the name to use for a new addition will
	fail if there's an existing entry that does not match the form
	"net%d".

	This is another of the handful of places that need an exception due to
	the hybrid nature of <interface type='hostdev'> (which is not exactly
	an <interface> or a <hostdev>, but is both at the same time).

	of fds to other variables, we should close the fds through those
	other names, and just use fds[] for pipe().

	command: avoid double close bugs
	KAMEZAWA Hiroyuki reported a nasty double-free bug when virCommand
	is used to convert a string into input to a child command.  The
	problem is that the poll() loop of virCommandProcessIO would close()
	the write end of the pipe in order to let the child see EOF, then
	the caller virCommandRun() would also close the same fd number, with
	the second close possibly nuking an fd opened by some other thread
	in the meantime.  This in turn can have all sorts of bad effects.

	The bug has been present since the introduction of virCommand in
	commit f16ad06f.

	This is based on his first attempt at a patch, at
	https://bugzilla.redhat.com/show_bug.cgi?id=823716

	* src/util/command.c (_virCommand): Drop inpipe member.

	build: silence libtool during tests
	Libtool is picky about linking against a module library (aka a .so);
	giving lots of warnings like this in the tests directory:

	  CCLD   networkxml2argvtest

	*** Warning: Linking the executable networkxml2argvtest against the loadable module
	*** libvirt_driver_network.so is not portable!

	Fix that by splitting things into a convenience library which can
	be used directly by the tests, and making the real .so just wrap
	the convenience library.

	Based on a suggestion by Daniel P. Berrange.

	* configure.ac (--with-driver-modules): Fix help test.
	* src/Makefile.am (libvirt_driver_xen.la, libvirt_driver_libxl.la)

	Fix linking to DTrace probes file
	There was no rule forcing libvirt_qemu_probes.o to be built
	before libvirt_qemu_probes.lo was used. Also libvirtd was
	still referencing the .o file, rather than the .lo file.

	Both the .lo and .o file must be listed as DEPENDENCIES,
	otherwise libtool will unhelpfully delete the .o file
	once the .lo file is created.

	Only build server side drivers as modules
	The driver modules all use symbols which are defined in libvirt.so.
	Thus for loading of modules to work, the binary that libvirt.so
	is linked to must export its symbols back to modules. If the
	libvirt.so itself is dlopen()d then the RTLD_GLOBAL flag must
	be set. Unfortunately few, if any, programming languages use
	the RTLD_GLOBAL flag when loading modules :-( This means is it
	not practical to use driver modules for any libvirt client side
	drivers (OpenVZ, VMWare, Hyper-V, Remote client, test).

	This patch changes the build process so only server side drivers
	are built as modules (Xen, QEMU, LXC, UML)

	Revert "rpc: Discard non-blocking calls only when necessary"
	This reverts commit b1e374a7ac56927cfe62435179bf0bba1e08b372, which was
	rather bad since I failed to consider all sides of the issue. The main
	things I didn't consider properly are:

	- a thread which sends a non-blocking call waits for the thread with
	  the buck to process the call
	- the code doesn't expect non-blocking calls to remain in the queue
	  unless they were already partially sent

	Thus, the reverted patch actually breaks more than what it fixes and
	clients (which may even be libvirtd during p2p migrations) will likely
	end up in a deadlock.

	storage backend: Add RBD (RADOS Block Device) support
	This patch adds support for a new storage backend with RBD support.

	RBD is the RADOS Block Device and is part of the Ceph distributed storage
	system.

	It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only
	supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only.

	To function this backend relies on librbd and librados being present on the
	local system.

	The backend also supports Cephx authentication for safe authentication with
	the Ceph cluster.

	For storing credentials it uses the built-in secret mechanism of libvirt.

	Fix potential events deadlock when unref'ing virConnectPtr
	When the last reference to a virConnectPtr is released by
	libvirtd, it was possible for a deadlock to occur in the
	virDomainEventState functions. The virDomainEventStatePtr
	holds a reference on virConnectPtr for each registered
	callback. When removing a callback, the virUnrefConnect
	function is run. If this causes the last reference on the
	virConnectPtr to be released, then virReleaseConnect can
	be run, which in turns calls qemudClose. This function has
	a call to virDomainEventStateDeregisterConn which is intended
	to remove all callbacks associated with the virConnectPtr
	instance. This will try to grab a lock on virDomainEventState
	but this lock is already held. Deadlock ensues

	Thread 1 (Thread 0x7fcbb526a840 (LWP 23185)):

	Since each callback associated with a virConnectPtr holds a
	reference on virConnectPtr, it is impossible for the qemudClose
	method to be invoked while any callbacks are still registered.
	Thus the call to virDomainEventStateDeregisterConn must in fact
	be a no-op. Thus it is possible to just remove all trace of
	virDomainEventStateDeregisterConn and avoid the deadlock.

	nwfilter: Add support for ipset
	This patch adds support for the recent ipset iptables extension
	to libvirt's nwfilter subsystem. Ipset allows to maintain 'sets'
	of IP addresses, ports and other packet parameters and allows for
	faster lookup (in the order of O(1) vs. O(n)) and rule evaluation
	to achieve higher throughput than what can be achieved with
	individual iptables rules.

	On the command line iptables supports ipset using

	iptables ... -m set --match-set <ipset name> <flags> -j ...

	where 'ipset name' is the name of a previously created ipset and
	flags is a comma-separated list of up to 6 flags. Flags use 'src' and 'dst'
	for selecting IP addresses, ports etc. from the source or
	destination part of a packet. So a concrete example may look like this:

	iptables -A INPUT -m set --match-set test src,src -j ACCEPT

	Since ipset management is quite complex, the idea was to leave ipset 
	management outside of libvirt but still allow users to reference an ipset.
	The user would have to make sure the ipset is available once the VM is
	started so that the iptables rule(s) referencing the ipset can be created.

	Using XML to describe an ipset in an nwfilter rule would then look as
	follows:

	  <rule action='accept' direction='in'>
	    <all ipset='test' ipsetflags='src,src'/>
	  </rule>

	The two parameters on the command line are also the two distinct XML attributes
	'ipset' and 'ipsetflags'.

	FYI: Here is the man page for ipset:

	https://ipset.netfilter.org/ipset.man.html

	  2. hypervisor: `total cpu usage' - `vcpu usage'

	The param 'vcpu_time' is for getting vcpu usages.

	qemu: Rollback on used USB devices
	One of our latest USB device handling patches
	05abd1507d66aabb6cad12eeafeb4c4d1911c585 introduced a regression.
	That is, we first create a temporary list of all USB devices that
	are to be used by domain just starting up. Then we iterate over and
	check if a device from the list is in the global list of currently
	assigned devices (activeUsbHostdevs). If not, we add it there and
	continue with next iteration then. But if a device from temporary
	list is either taken already or adding to the activeUsbHostdevs fails,
	we remove all devices in temp list from the activeUsbHostdevs list.
	Therefore, if a device is already taken we remove it from
	activeUsbHostdevs even if we should not. Thus, next time we allow
	the device to be assigned to another domain.

	Remount cgroups controllers after setting up new /sys in LXC
	Normal practice is for cgroups controllers to be mounted at
	/sys/fs/cgroup. When setting up a container, /sys is mounted
	with a new sysfs instance, thus we must re-mount all the
	cgroups controllers. The complexity is that we must mount
	them in the same layout as the host OS. ie if 'cpu' and 'cpuacct'
	were mounted at the same location in the host we must preserve
	this in the container. Also if any controllers are co-located
	we must setup symlinks from the individual controller name to
	the co-located mount-point

	Trim /proc & /sys subtrees before mounting new instances
	Both /proc and /sys may have sub-mounts in them from the host
	OS. We must explicitly unmount them all before mounting the
	new instance over that location. If we don't then /proc/mounts
	will show the sub-mounts as existing, even though nothing will
	be able to access them, due to the over-mount.

	Mount fresh instance of sysfs/selinux in LXC
	Currently to make sysfs readonly, we remount the existing
	instance and then bind it readonly. Unfortunately this means
	sysfs is still showing device objects wrt the host OS namespace.
	We need it to reflect the container namespace, so we must mount
	a completely new instance of it. Do the same for selinuxfs since
	there is no benefit to bind mounting & this lets us simplify
	the code.

	Convert the LXC driver to use the security driver API for mount options
	Instead of hardcoding use of SELinux contexts in the LXC driver,

	Some security drivers require special options to be passed to
	the mount system call. Add a security driver API for handling

	Add support for LXC specific SELinux configuration
	The SELinux policy for LXC uses a different configuration file
	than the traditional svirt one. Thus we need to load

	something like this:

	 process = "system_u:system_r:svirt_lxc_net_t:s0"
	 file = "system_u:object_r:svirt_lxc_file_t:s0"
	 content = "system_u:object_r:virt_var_lib_t:s0"

	cleverly designed to be parsable by virConfPtr

	Use private data struct in SELinux driver
	Currently the SELinux driver stores its state in a set of global
	variables. This switches it to use a private data struct instead.
	This will enable different instances to have their own data.

	Don't enable the AppArmour security driver with LXC
	The AppArmour driver does not currently have support for LXC
	so ensure that when probing, it claims to be disabled

	information per hypervisor, pass the virtualization driver name

	nodeinfo: Get the correct CPU number on AMD Magny Cours platform
	"Instead of developing one CPU with 12 cores, the Magny Cours is
	actually two 6 core “Bulldozer” CPUs combined in to one package"

	I.e, each package has two NUMA nodes, and the two numa nodes share
	the same core ID set (0-6), which means parsing the cores number
	from sysfs doesn't work in this case.

	And the wrong CPU number could cause three problems for libvirt:

	1) performance lost

	  A domain without "cpuset" or "placement='auto'" (to drive numad)
	specified will be only pinned to part of the CPUs.

	2) domain can be started

	  If a domain uses numad, and the advisory nodeset returned from
	numad contains node which exceeds the range of wrong total CPU
	number. The domain will fail to start, as the bitmask passed to
	sched_setaffinity could be fully filled with zero.

	3) wrong CPU number affects lots of stuffs.

	  E.g. for command "virsh vcpuinfo", "virsh vcpupin", it will always
	output with the truncated CPU list.

	For more details:

	https://www.redhat.com/archives/libvir-list/2012-May/msg00607.html

	This patch is to fix the problem by parsing /proc/cpuinfo to get
	the value of field "cpu cores", and use it as nodeinfo->cores if
	it's greater than the cores number from sysfs.

	  2:  20  20  10  20
	  3:  20  20  20  10

	This patch is to fix the problem by using the CPU index in
	caps->host.numaCell[i]->cpus[i] to set the bitmask instead of
	assuming the CPU index of the NUMA nodes are always sequential.

	qemu: Don't skip detection of virtual cpu's on non KVM targets
	This patch lifts the limit of calling thread detection code only on KVM
	guests. With upstream qemu the thread mappings are reported also on
	non-KVM machines.

	QEMU adopted the thread_id information from the kvm branch.

	To remain compatible with older upstream versions of qemu the check is
	attempted but the failure to detect threads (or even run the monitor
	command - on older versions without SMP support) is treated non-fatal
	and the code reports one vCPU with pid of the hypervisor (in same
	fashion this was done on non-KVM guests).

	This ensures that correct information is reported by the
	virDomainGetVcpus API and "virsh vcpuinfo".

	A failure to obtain the thread<->vcpu mapping is treated non-fatal and
	the mapping is not updated in a case of failure as not all versions of

	Report error when parsing character device target type
	No useful error was being reported when an invalid character device
	target type is specified in the domainXML. E.g.

	    <console type="pty">
	      <source path="/dev/pts/2"/>
	      <target type="kvm" port="0"/>
	    </console>
	    ...

	resulted in

	error: An error occurred, but the cause is unknown

	With this small patch, the error is more helpful

	Not only support CPU placement now.

2012-05-09  Osier Yang  <jyang@redhat.com>

	numad: Check numactl-devel if compiled with numad support
	Since now we pre-set memory policy using libnuma to fully
	drive numad, it needs to check numactl-devel if "with_numad"
	is "yes".

	configure with groups "--with-numad=yes --with-numactl=yes",
	"--with-numad=no --with-numactl=yes", "--with-numad=yes
	--with-numactl=yes" works fine after the change.

	numad: Divide cur_balloon by 1024 before passing it to numad
	Numad expects MB by default.

	numad: Always output 'placement' of <vcpu>
	<vcpu> is not an optional node. The value for its 'placement'
	actually always defaults to 'static' in the underlying codes.
	(Even no 'cpuset' and 'placement' is specified, the domain
	process will be pinned to all the available pCPUs).

2012-05-09  Osier Yang  <jyang@redhat.com>

	numad: Copy 'placement' of <numatune> to <vcpu> by default
	With this patch, one can also fully drive numad by:

	  <vcpu>2</vcpu>
	  <numatune>
	    <memory placement='auto'/>
	  </numatune>

	New tests are added.

2012-05-09  Osier Yang  <jyang@redhat.com>

	numad: Set memory policy from numad advisory nodeset
	Though numad will manage the memory allocation of task dynamically,
	it wants management application (libvirt) to pre-set the memory
	policy according to the advisory nodeset returned from querying numad,
	(just like pre-bind CPU nodeset for domain process), and thus the
	performance could benefit much more from it.

	This patch introduces new XML tag 'placement', value 'auto' indicates
	whether to set the memory policy with the advisory nodeset from numad,
	and its value defaults to the value of <vcpu> placement, or 'static'
	if 'nodeset' is specified. Example of the new XML tag's usage:

	  <numatune>
	    <memory placement='auto' mode='interleave'/>
	  </numatune>

	Just like what current "numatune" does, the 'auto' numa memory policy
	setting uses libnuma's API too.

	If <vcpu> "placement" is "auto", and <numatune> is not specified
	explicitly, a default <numatume> will be added with "placement"
	set as "auto", and "mode" set as "strict".

	The following XML can now fully drive numad:

	1) <vcpu> placement is 'auto', no <numatune> is specified.

	   <vcpu placement='auto'>10</vcpu>

	2) <vcpu> placement is 'auto', no 'placement' is specified for
	   <numatune>.

	   <vcpu placement='auto'>10</vcpu>
	   <numatune>
	     <memory mode='interleave'/>
	   </numatune>

	And it's also able to control the CPU placement and memory policy
	independently. e.g.

	1) <vcpu> placement is 'auto', and <numatune> placement is 'static'

	   <vcpu placement='auto'>10</vcpu>
	   <numatune>
	     <memory mode='strict' nodeset='0-10,^7'/>
	   </numatune>

	2) <vcpu> placement is 'static', and <numatune> placement is 'auto'

	   <vcpu placement='static' cpuset='0-24,^12'>10</vcpu>
	   <numatune>
	     <memory mode='interleave' placement='auto'/>
	   </numatume>

	A follow up patch will change the XML formatting codes to always output
	'placement' for <vcpu>, even it's 'static'.

	util: set src_pid for virNetlinkCommand when appropriate
	Until now, the nl_pid of the source address of every message sent by
	virNetlinkCommand has been set to the value of getpid(). Most of the
	time this doesn't matter, and in the one case where it does
	(communication with lldpad), it previously was the proper thing to do,
	because the netlink event service (which listens on a netlink socket
	for unsolicited messages from lldpad) coincidentally always happened
	to bind with a local nl_pid == getpid().

	With the fix for:

	  https://bugzilla.redhat.com/show_bug.cgi?id=816465

	that particular nl_pid is now effectively a reserved value, so the
	netlink event service will always bind to something else
	(coincidentally "getpid() + (1 << 22)", but it really could be
	anything). The result is that communication between lldpad and
	libvirtd is broken (lldpad gets a "disconnected" error when it tries
	to send a directed message).

	The solution to this problem caused by a solution, is to query the
	netlink event service's nlhandle for its "local_port", and send that
	as the source nl_pid (but only when sending to lldpad, of course - in
	other cases we maintain the old behavior of sending getpid()).

	There are two cases where a message is being directed at lldpad - one
	in virNetDevLinkDump, and one in virNetDevVPortProfileOpSetLink.

	The case of virNetDevVPortProfileOpSetLink is simplest to explain -
	only if !nltarget_kernel, i.e. the message isn't targetted for the
	kernel, is the dst_pid set (by calling
	virNetDevVPortProfileGetLldpadPid()), so only in that case do we call
	virNetlinkEventServiceLocalPid() to set src_pid.

	For virNetDevLinkDump, it's a bit more complicated. The call to
	virNetDevVPortProfileGetLldpadPid() was effectively up one level (in
	virNetDevVPortProfileOpCommon), although obscured by an unnecessary
	passing of a function pointer. This patch removes the function
	pointer, and calls virNetDevVPortProfileGetLldpadPid() directly in
	virNetDevVPortProfileOpCommon - if it's doing this, it knows that it
	should also call virNetlinkEventServiceLocalPid() to set src_pid too;
	then it just passes src_pid and dst_pid down to
	virNetDevLinkDump. Since (src_pid == 0 && dst_pid == 0) implies that
	the kernel is the destination, there is no longer any need to send
	nltarget_kernel as an arg to virNetDevLinkDump, so it's been removed.

	The disparity between src_pid being int and dst_pid being uint32_t may
	be a bit disconcerting to some, but I didn't want to complicate
	virNetlinkEventServiceLocalPid() by having status returned separately
	from the value.

2012-05-08  Laine Stump  <laine@laine.org>

	util: function to get local nl_pid used by netlink event socket
	This value will be needed to set the src_pid when sending netlink
	messages to lldpad. It is part of the solution to:

	  https://bugzilla.redhat.com/show_bug.cgi?id=816465

	Note that libnl's port generation algorithm guarantees that the
	nl_socket_get_local_port() will always be > 0 (since it is "getpid() +
	(n << 22>" where n is always < 1024), so it is okay to cast the
	uint32_t to int (thus allowing us to use -1 as an error sentinel).

2012-05-08  Laine Stump  <laine@laine.org>

	util: allow specifying both src and dst pid in virNetlinkCommand
	Until now, virNetlinkCommand has assumed that the nl_pid in the source
	address of outgoing netlink messages should always be the return value
	of getpid(). In most cases it actually doesn't matter, but in the case
	of communication with lldpad, lldpad saves this info and later uses it
	to send netlink messages back to libvirt. A recent patch to fix Bug
	816465 changed the order of the universe such that the netlink event
	service socket is no longer bound with nl_pid == getpid(), so lldpad
	could no longer send unsolicited messages to libvirtd. Adding src_pid
	as an argument to virNetlinkCommand() is the first step in notifying
	lldpad of the proper address of the netlink event service socket.

	util: fix libvirtd startup failure due to netlink error
	This is part of the solution to the problem detailed in:

	  https://www.redhat.com/archives/libvir-list/2012-May/msg00202.htm

	A short explanation is included in the comments of the patch itself.

	Note that this patch by itself breaks communication between lldpad and
	libvirtd, so the other 3 patches in the series must be applied at the
	same time as this patch.

	qemu: Emit compatible XML when migrating a domain
	When we added the default USB controller into domain XML, we efficiently
	broke migration to older versions of libvirt that didn't support USB
	controllers at all (0.9.4 and earlier) even for domains that don't use
	anything that the older libvirt can't provide. We still want to present
	the default USB controller in any XML seen by a user/app but we can
	safely remove it from the domain XML used during migration. If we are
	migrating to a new enough libvirt, it will add the controller XML back,
	while older libvirt won't be confused with it although it will still
	tell qemu to create the controller.

	Similar approach can be used in the future whenever we find out we
	always enabled some kind of device without properly advertising it in
	domain XML.

	fails as expected (well, the error message is lousy), but the next
	dumpxml shows that the domain was modified anyway.  Worse, that means
	if you save the domain then restore it, the restore will likely fail
	due to throttling being unsupported, even though no throttling should

	build: make ATTRIBUTE_NONNULL() a NOP unless STATIC_ANALYSIS is on
	The ATTRIBUTE_NONNULL(m) macro normally resolves to the gcc builtin
	__attribute__((__nonnull__(m))). The effect of this in gcc is
	unfortunately only to make gcc believe that "m" can never possibly be
	NULL, *not* to add in any checks to guarantee that it isn't ever NULL
	(i.e. it is an optimization aid, *not* something to verify code
	correctness.) - see the following gcc bug report for more details:

	  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17308

	Static source analyzers such as clang and coverity apparently can use
	ATTRIBUTE_NONNULL(), though, to detect dead code (in the case that the
	arg really is guaranteed non-NULL), as well as situations where an
	obviously NULL arg is given to the function.

	https://bugzilla.redhat.com/show_bug.cgi?id=815270 is a good example
	of a bug caused by erroneous application of ATTRIBUTE_NONNULL().
	Several people spent a long time staring at this code and not finding
	the problem, because the problem wasn't in the function itself, but in
	the prototype that specified ATTRIBUTE_NONNULL() for an arg that
	actually *wasn't* always non-NULL, and caused a segv when dereferenced
	(even though the code that dereferenced the pointer was inside an if()
	that checked for a NULL pointer, that code was optimized out by gcc).

	There may be some very small gain to be had from the optimizations
	that can be inferred from ATTRIBUTE_NONNULL(), but it seems safer to
	err on the side of generating code that behaves as expected, while
	turning on the attribute for static analyzers.

	Make lxcContainerSetStdio the last thing to be called in container startup
	Once lxcContainerSetStdio is invoked, logging will not work as

	Ensure logging is initialized early in libvirt_lxc

	Ensure LXC security driver is set unconditonally
	The driver->securityDriverName field may be NULL, if automatic
	probing is used to determine security driver. This meant that
	unless selinux was explicitly requested in lxc.conf, it was
	not being sent to the libvirt_lxc process.

	The driver->securityManager field is guaranteed non-NULL, since
	there will always be the 'none' security driver present if
	nothing else exists. So use that to set the driver name for
	libvirt_lxc

	Ensure libvirt_lxc process loads the live XML config
	Currently the libvirt_lxc process uses VIR_DOMAIN_XML_INACTIVE
	when loading the XML for the container. This means it loses

	Further there is an inconsistency in the libvirt LXC driver
	whereby it saves the live config XML and then later overwrites
	the file with the live status XML instead. Add a comment about
	this for future reference.

	qemu_agent: Report error class at least
	Currently, qemu GA is not providing 'desc' field for errors like

	blockjob: fix block-stream bandwidth race
	With RHEL 6.2, virDomainBlockPull(dom, dev, bandwidth, 0) has a race
	with non-zero bandwidth: there is a window between the block_stream
	and block_job_set_speed monitor commands where an unlimited amount
	of data was let through, defeating the point of a throttle.

	This race was first identified in commit a9d3495e, and libvirt was
	able to reduce the size of the window for that race.  In the meantime,
	the qemu developers decided to fix things properly; per this message:
	https://lists.gnu.org/archive/html/qemu-devel/2012-04/msg03793.html
	the fix will be in qemu 1.1, and changes block-job-set-speed to use
	a different parameter name, as well as adding a new optional parameter
	to block-stream, which eliminates the race altogether.

	Since our documentation already mentioned that we can refuse a non-zero
	bandwidth for some hypervisors, I think the best solution is to do
	just that for RHEL 6.2 qemu, so that the race is obvious to the user
	(anyone using stock RHEL 6.2 binaries won't have this patch, and anyone
	building their own libvirt with this patch for RHEL can also rebuild
	qemu to get the modern semantics, so it is no real loss in behavior).

	Meanwhile the code must be fixed to honor actual qemu 1.1 naming.
	Rename the parameter to 'modern', since the naming difference now
	covers more than just 'async' block-job-cancel.  And while at it,
	fix an unchecked integer overflow.

	* src/qemu/qemu_monitor.h (enum BLOCK_JOB_CMD): Drop unused value,
	rename enum to match conventions.
	* src/qemu/qemu_monitor.c (qemuMonitorBlockJob): Reflect enum rename.
	* src/qemu_qemu_monitor_json.h (qemuMonitorJSONBlockJob): Likewise.
	* src/qemu/qemu_monitor_json.c (qemuMonitorJSONBlockJob): Likewise,
	and support difference between RHEL 6.2 and qemu 1.1 block pull.
	* src/qemu/qemu_driver.c (qemuDomainBlockJobImpl): Reject
	bandwidth during pull with too-old qemu.
	* src/libvirt.c (virDomainBlockPull, virDomainBlockRebase):

	qemu: Use common helper when probing qemu capabilities
	QEMU binary is called several times when we probe different kinds of

	helper so that all probes use a consistent way of invoking qemu.

	qemu: improve errors related to offline domains
	https://bugzilla.redhat.com/show_bug.cgi?id=816662 pointed out
	that attempting 'virsh blockpull' on an offline domain gave a
	misleading error message about qemu lacking support for the
	operation, even when qemu was specifically updated to support it.
	The real problem is that we have several capabilities that are
	only determined when starting a domain, and therefore are still
	clear when first working with an inactive domain (namely, any
	capability set by qemuMonitorJSONCheckCommands).

	While this patch was able to hoist an existing check in one of the
	three culprits, it had to add redundant checks in the other two
	places (because you always have to check for an active domain after
	obtaining a VM job lock, but the capability bits were being checked
	prior to obtaining the job lock).

	Someday it would be nice to patch libvirt to cache the set of
	capabilities per qemu binary (as determined by inode and timestamp),
	rather than re-probing the binary every time a domain is started,
	and to teach the cache how to query the monitor during the one
	time the probe is made rather than having to wait until a guest
	is started; then, a capability probe would succeed even for offline
	guests because it just refers to the cache, and the single check for
	an active domain after grabbing the job lock would be sufficient.
	But since that will involve a lot more coding, I'm happy to go
	with this simpler solution for an immediate solution.

	* src/qemu/qemu_driver.c (qemuDomainPMSuspendForDuration)
	(qemuDomainSnapshotCreateXML, qemuDomainBlockJobImpl): Check for
	offline state before checking an online-only cap.

	util: fix error messages in virNetlinkEventServiceStart
	Some of the error messages in this function should have been
	virReportSystemError (since they have an errno they want to log), but
	were mistakenly written as netlinkError, which expects a libvirt error
	code instead. The result was that when one of the errors was
	encountered, "No error message provided" would be printed instead of
	something meaningful (see

	qemu: Avoid bogus error at the end of tunnelled migration
	Once qemu monitor reports migration has completed, we just closed our
	end of the pipe and let migration tunnel die. This generated bogus error
	in case we did so before the thread saw EOF on the pipe and migration
	was aborted even though it was in fact successful.

	With this patch we first wake up the tunnel thread and once it has read
	all data from the pipe and finished the stream we close the
	filedescriptor.

	A small additional bonus of this patch is that real errors reported
	inside qemuMigrationIOFunc are not overwritten by virStreamAbort any
	more.

	qemu: Fix detection of failed migration
	When QEMU reported failed or canceled migration, we correctly detected

	rpc: Discard non-blocking calls only when necessary
	Currently, non-blocking calls are either sent immediately or discarded
	in case sending would block. This was implemented based on the
	assumption that the non-blocking keepalive call is not needed as there
	are other calls in the queue which would keep the connection alive.
	However, if those calls are no-reply calls (such as those carrying
	stream data), the remote party knows the connection is alive but since
	we don't get any reply from it, we think the connection is dead.

	This is most visible in tunnelled migration. If it happens to be longer
	than keepalive timeout (30s by default), it may be unexpectedly aborted
	because the connection is considered to be dead.

	With this patch, we only discard non-blocking calls when the last call
	with a thread is completed and thus there is no thread left to keep
	sending the remaining non-blocking calls.

	util: fix crash when starting macvtap interfaces
	This patch resolves https://bugzilla.redhat.com/show_bug.cgi?id=815270

	The function virNetDevMacVLanVPortProfileRegisterCallback() takes an
	arg "virtPortProfile", and was checking it for non-NULL before using
	it. However, the prototype for
	virNetDevMacVLanPortProfileRegisterCallback had marked that arg with
	ATTRIBUTE_NONNULL(). Contrary to what one may think,
	ATTRIBUTE_NONNULL() does not provide any guarantee that an arg marked
	as such really is always non-null; the only effect to the code
	generated by gcc, is that gcc *assumes* it is non-NULL; this results
	in, for example, the check for a non-NULL value being optimized out.

	(Unfortunately, this code removal only occurs when optimization is
	enabled, and I am in the habit of doing local builds with optimization
	off to ease debugging, so the bug didn't show up in my earlier local
	testing).

	In general, virPortProfile might always be NULL, so it shouldn't be
	marked as ATTRIBUTE_NONNULL. One other function prototype made this
	same error, so this patch fixes it as well.

	build: fix bootstrap on RHEL
	Commit 8fe455fd364cd7462e02170084c45a58ee302cc3 tried to work around
	a regression introduced in upstream gnulib that requires gettext 0.18
	or newer on all projects using bootstrap, by making libvirt require
	gettext 0.18.  But this fails on RHEL 6.2, which still ships gettext
	0.17.  Revert that change, and instead, import the latest round of
	gnulib updates that fix that problem properly.

	If you have already built in the window where libvirt required 0.18,
	be aware that incremental updates may run into problems: this is
	because 'autopoint --force' will not downgrade m4/po.m4 back to an
	older version, but it must be downgraded back to 0.17 levels to work
	with this patch.  You may either manually remove that file then rerun
	bootstrap, or it may prove easier to just clean up all non-git files
	to start from a clean slate.

	* bootstrap.conf: Revert minimum gettext back to 0.17.
	* configure.ac: Likewise.
	* .gnulib: Update to latest, for bootstrap fixes.
	* bootstrap: Resync from gnulib.

	blockjob: enhance xml to track mirrors across libvirtd restart
	In order to track a block copy job across libvirtd restarts, we
	need to save internal XML that tracks the name of the file
	holding the mirror.  Displaying this name in dumpxml might also
	be useful to the user, even if we don't yet have a way to (re-)
	start a domain with mirroring enabled up front.  This is done
	with a new <mirror> sub-element to <disk>, as in:

	    <disk type='file' device='disk'>
	      <driver name='qemu' type='raw'/>
	      <source file='/var/lib/libvirt/images/original.img'/>
	      <mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/>
	      ...
	    </disk>

	For now, the element is output-only, in live domains; it is ignored
	when defining a domain or hot-plugging a disk (since those contexts
	use VIR_DOMAIN_XML_INACTIVE in parsing).  The 'ready' attribute appears
	when libvirt knows that the job has changed from the initial pulling
	phase over to the mirroring phase, although absence of the attribute
	is not a sure indicator of the current phase.  If we come up with a way
	to make qemu start with mirroring enabled, we can relax the xml
	restriction, and allow <mirror> (but not attribute 'ready') on input.
	Testing active-only XML meant tweaking the testsuite slightly, but it
	was worth it.

	* docs/formatdomain.html.in (elementsDisks): Document it.

	blockjob: add 'blockcopy' to virsh
	Rather than further overloading 'blockpull', I decided to create a
	new virsh command to expose the new flags of virDomainBlockRebase.

	Blocking until the command completes naturally is pointless, since
	the block copy job is intended to run indefinitely.  Instead, I
	made the command support three --wait modes: by default, it runs until
	mirroring is started; with --pivot, it pivots as soon as mirroring
	is started; and with --finish, it aborts (for a clean copy) as
	soon as mirroring is started.

	* tools/virsh.c (VSH_CMD_BLOCK_JOB_COPY): New mode.
	(blockJobImpl): Support new flags.
	(cmdBlockCopy): New command.
	(cmdBlockJob): Support new job info, new abort flag.
	* tools/virsh.pod (blockcopy, blockjob): Document the new command
	and flags.

2012-04-23  Eric Blake  <eblake@redhat.com>

	blockjob: add new API flags
	This patch introduces a new block job, useful for live storage
	migration using pre-copy streaming.  Justification for including
	this under virDomainBlockRebase rather than adding a new command
	includes: 1) there are now two possible block jobs in qemu, with
	virDomainBlockRebase starting either type of command, and
	virDomainBlockJobInfo and virDomainBlockJobAbort working to end
	either type; 2) reusing this command allows distros to backport
	this feature to the libvirt 0.9.10 API without a .so bump.

	Note that a future patch may add a more powerful interface named
	virDomainBlockJobCopy, dedicated to just the block copy job, in
	order to expose even more options (such as setting an arbitrary
	format type for the destination without having to probe it from a
	pre-existing destination file); adding a new command for targetting
	just block copy would be similar to how we already have
	virDomainBlockPull for targetting just the block pull job.

	Using a live VM with the backing chain:
	  base <- snap1 <- snap2
	as the starting point, we have:

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY)
	creates /path/to/copy with the same format as snap2, with no backing
	file, so entire chain is copied and flattened

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_COPY_RAW)
	creates /path/to/copy as a raw file, so entire chain is copied and
	flattened

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_SHALLOW)
	creates /path/to/copy with the same format as snap2, but with snap1 as
	a backing file, so only snap2 is copied.

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_REUSE_EXT)
	reuse existing /path/to/copy (must have empty contents, and format is
	probed[*] from the metadata), and copy the full chain

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_REUSE_EXT|
	    VIR_DOMAIN_BLOCK_REBASE_SHALLOW)
	reuse existing /path/to/copy (contents must be identical to snap1,
	and format is probed[*] from the metadata), and copy only the contents
	of snap2

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_REUSE_EXT|
	    VIR_DOMAIN_BLOCK_REBASE_SHALLOW|VIR_DOMAIN_BLOCK_REBASE_COPY_RAW)
	reuse existing /path/to/copy (must be raw volume with contents
	identical to snap1), and copy only the contents of snap2

	Less useful combinations:

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_SHALLOW|
	    VIR_DOMAIN_BLOCK_REBASE_COPY_RAW)
	fail if source is not raw, otherwise create /path/to/copy as raw and
	the single file is copied (no chain involved)

	- virDomainBlockRebase(dom, disk, "/path/to/copy", 0,
	    VIR_DOMAIN_BLOCK_REBASE_COPY|VIR_DOMAIN_BLOCK_REBASE_REUSE_EXT|
	    VIR_DOMAIN_BLOCK_REBASE_COPY_RAW)
	makes little sense: the destination must be raw but have no contents,
	meaning that it is an empty file, so there is nothing to reuse

	The other three flags are rejected without VIR_DOMAIN_BLOCK_COPY.

	[*] Note that probing an existing file for its format can be a security
	risk _if_ there is a possibility that the existing file is 'raw', in
	which case the guest can manipulate the file to appear like some other
	format.  But, by virtue of the VIR_DOMAIN_BLOCK_REBASE_COPY_RAW flag,
	it is possible to avoid probing of raw files, at which point, probing
	of any remaining file type is no longer a security risk.

	It would be nice if we could issue an event when pivoting from phase 1
	to phase 2, but qemu hasn't implemented that, and we would have to poll
	in order to synthesize it ourselves.  Meanwhile, qemu will give us a
	distinct job info and completion event when we either cancel or pivot
	to end the job.  Pivoting is accomplished via the new:

	virDomainBlockJobAbort(dom, disk, VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT)

	Management applications can pre-create the copy with a relative
	backing file name, and use the VIR_DOMAIN_BLOCK_REBASE_REUSE_EXT
	flag to have qemu reuse the metadata; if the management application
	also copies the backing files to a new location, this can be used
	to perform live storage migration of an entire backing chain.

	virnetserver: handle sigaction correctly
	POSIX says that sa_sigaction is only safe to use if sa_flags
	includes SA_SIGINFO; conversely, sa_handler is only safe to
	use when flags excludes that bit.  Gnulib doesn't guarantee
	an implementation of SA_SIGINFO, but does guarantee that
	if SA_SIGINFO is undefined, we can safely define it to 0 as
	long as we don't dereference the 2nd or 3rd argument of
	any handler otherwise registered via sa_sigaction.

	Based on a report by Wen Congyang.

	* src/rpc/virnetserver.c (SA_SIGINFO): Stub for mingw.
	(virNetServerSignalHandler): Avoid bogus dereference.

	The policy kit and HAL node device drivers both require a DBus connection. The HAL device code further requires that the DBus connection is integrated with the event loop and provides such glue logic itself.
	The forthcoming FirewallD integration also requires a
	dbus connection with event loop integration. Thus we need
	to pull the current event loop glue out of the HAL driver.

	Thus we create src/util/virdbus.{c,h} files. This contains
	just one method virDBusGetSystemBus() which obtains a handle
	to the single shared system bus instance, with event glue
	automagically setup.

	blockjob: add virsh blockpull --wait
	I'm tired of shell-scripting to wait for completion of a block pull,
	when virsh can be taught to do the same.  I couldn't quite reuse
	vshWatchJob, as this is not a case of a long-running command where
	a second thread must be used to probe job status (at least, not unless
	I make virsh start doing blocking waits for an event to fire), but it
	served as inspiration for my simpler single-threaded loop.  There is
	up to a half-second delay between sending SIGINT and the job being
	aborted, but I didn't think it worth the complexity of a second thread
	and use of poll() just to minimize that delay.

	xen: do not use ioemu type for any emulated NIC
	When using the xm/xend stack to manage instances there is a bug
	that causes the emulated interfaces to be unusable when the vif
	config contains type=ioemu.

	The current code already has a special quirk to not use this
	keyword if no specific model is given for the emulated NIC
	(defaulting to rtl8139).
	Essentially it works because regardless of the type argument,i
	the Xen stack always creates emulated and paravirt interfaces and
	lets the guest decide which one to use. So neither xl nor xm stack
	actually require the type keyword for emulated NICs.

	As explained in previous patch, numad will balance the affinity

	numad: Convert node list to cpumap before setting affinity
	Instead of returning a CPUs list, numad returns NUMA node
	list instead, this patch is to convert the node list to
	cpumap before affinity setting. Otherwise, the domain
	processes will be pinned only to CPU[$numa_cell_num],
	which will cause significiant performance losses.

	Also because numad will balance the affinity dynamically,
	reflecting the cpuset from numad back doesn't make much
	sense then, and it may just could produce confusion for
	the users. Thus the better way is not to reflect it back
	to XML. And in this case, it's better to ignore the cpuset
	when parsing XML.

	The codes to update the cpuset is removed in this patch
	incidentally, and there will be a follow up patch to ignore
	the manually specified "cpuset" if "placement" is "auto",
	and document will be updated too.

	xend_internal: Use domain/status for shutdown check
	On newer xend (v3.x and after) there is no state and domid reported
	for inactive domains. When initially creating connections this is
	handled in various places by assigning domain->id = -1.
	But once an instance has been running, the id is set to the current
	domain id. And it does not change when the instance is shut down.
	So when querying the domain info, the hypervisor driver, which gets
	asked first will indicate it cannot find information, then the
	xend driver is asked and will set the status to NOSTATE because it
	checks for the -1 domain id.
	Checking domain/status for 0 seems to be more reliable for that.

	One note: I am not sure whether the domain->id also should get set
	back to -1 whenever any sub-driver thinks the instance is no longer
	running.

	blockjob: allow for fast-finishing job
	In my testing, I was able to provoke an odd block pull failure:

	$ virsh blockpull dom vda --bandwidth 10000
	error: Requested operation is not valid: No active operation on device: drive-virtio-disk0

	merely by using gdb to artifically wait to do the block job set speed
	until after the pull had already finished.  But in reality, that should
	be a success, since the pull finished before we had a chance to set
	speed.  Furthermore, using a double job lock is not only annoying, but
	a bug in itself - if you do parallel virDomainBlockRebase, and hit
	the race window just right, the first call grabs the VM job to start
	a fast block job, then the second call grabs the VM job to start
	a long-running job with unspecified speed, then the first call finally
	regrabs the VM job and sets the speed, which ends up running the
	second job under the speed from the first call.  By consolidating
	things into a single job, we avoid opening that race, as well as reduce
	the time between starting the job and changing the speed, for less
	likelihood of the speed change happening after block job completion
	in the first place.

	* src/qemu/qemu_monitor.h (BLOCK_JOB_CMD): Add new mode.
	* src/qemu/qemu_driver.c (qemuDomainBlockRebase): Move secondary

	blockjob: wire up qemu async virDomainBlockJobAbort
	Without the VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC flag, libvirt will internally
	poll using qemu's "query-block-jobs" API and will not return until the
	operation has been completed.  API users are advised that this operation
	is unbounded and further interaction with the domain during this period
	may block.  Future patches may refactor things to allow other queries in
	parallel with this polling.  For older qemu, we synthesize the cancellation
	event, since qemu won't generate it.

	The choice of polling duration copies from the code in qemu_migration.c.

	blockjob: add API for async virDomainBlockJobAbort
	Block job cancellation can take a while.  Now that upstream qemu 1.1
	has asynchronous block cancellation, we want to expose that to the user.
	Therefore, the following updates are made to the virDomainBlockJob API:

	A new block job event type VIR_DOMAIN_BLOCK_JOB_CANCELED is managed by
	libvirt.  Regardless of the flags used with virDomainBlockJobAbort, this
	event will be raised: 1. when using synchronous block_job_cancel (the
	event will be synthesized by libvirt), and 2. whenever it is received
	from qemu (via asynchronous block-job-cancel).  Note that the event
	may be detected by libvirt even before the virDomainBlockJobAbort
	completes (always true when it is synthesized, but also possible if
	cancellation was fast).

	A new extension flag VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC is added to the
	virDomainBlockJobAbort API.  When enabled, this function will allow
	(but not require) asynchronous operation (ie, it returns as soon as
	possible, which might be before the job has actually been canceled).
	When the API is used in this mode, it is the responsibility of the
	caller to wait for a VIR_DOMAIN_BLOCK_JOB_CANCELED event or poll via
	the virDomainGetBlockJobInfo API to check the cancellation status.

	This patch also exposes the new flag through virsh, and makes virsh
	slightly easier to use (--async implies --abort, and lack of any options
	implies --info), although it leaves the qemu implementation for later
	patches.

	blockjob: add qemu capabilities related to block pull jobs
	RHEL 6.2 was released with an early version of block jobs, which only
	worked on the qed file format, where the commands were spelled with
	underscore (contrary to QMP style), and where 'block_job_cancel' was
	synchronous and did not trigger an event.

	The upcoming qemu 1.1 release has fixed these short-comings [1][2]:
	the commands now work on multiple file types, are spelled with dash,
	and 'block-job-cancel' is asynchronous and emits an event upon conclusion.

	[1]qemu commit 370521a1d6f5537ea7271c119f3fbb7b0fa57063
	[2]https://lists.gnu.org/archive/html/qemu-devel/2012-04/msg01248.html

	This patch recognizes the new spellings, and fixes virDomainBlockRebase
	to give a graceful error when talking to a too-old qemu on a partial
	rebase attempt.  Fixes for the new semantics will come later.  This
	patch also removes a bogus ATTRIBUTE_NONNULL mistakenly added in

	qemu: Fix deadlock when qemuDomainOpenConsole cleans up a connection
	The new safe console handling introduced a possibility to deadlock the
	qemu driver when a new console connection forcibly disconnects a
	previous console stream that belongs to an already closed connection.

	The virStreamFree function calls subsequently a the virReleaseConnect
	function that tries to lock the driver while discarding the connection,
	but the driver was already locked in qemuDomainOpenConsole.

	qemu: Avoid excessive calls to qemuDomainObjSaveJob()
	As reported by Daniel Berrangé, we have a huge performance regression
	for virDomainGetInfo() due to the change which makes virDomainEndJob()
	save the XML status file every time it is called. Previous to that
	change, 2000 calls to virDomainGetInfo() took ~2.5 seconds. After that
	change, 2000 calls to virDomainGetInfo() take 2 *minutes* 45 secs.

	We made the change to be able to recover from libvirtd restart in the
	middle of a job. However, only destroy and async jobs are taken care of.
	Thus it makes more sense to only save domain state XML when these jobs
	are started/stopped.

	snapshot: fix memory leak on error
	Leak introduced in commit 0436d32.  If we allocate an actions array,
	but fail early enough to never consume it with the qemu monitor
	transaction call, we leaked memory.

	But our semantics of making the transaction command free the caller's
	memory is awkward; avoiding the memory leak requires making every
	intermediate function in the call chain check for error.  It is much
	easier to fix things so that the function that allocates also frees,
	while the call chain leaves the caller's data intact.  To do that,
	I had to hack our JSON data structure to make it easy to protect a
	portion of an arbitrary JSON tree from being freed.

	* src/util/json.h (virJSONType): Name the enum.
	(_virJSONValue): New field.
	* src/util/json.c (virJSONValueFree): Use it to protect a portion

	test: fix build errors with gcc 4.7.0 and -O0
	When building on Fedora 17 (which uses gcc 4.7.0) with -O0 in CFLAGS,
	three of the tests failed to compile.

	cputest.c and qemuxml2argvtest.c had non-static structs defined
	inside the macro that was being repeatedly invoked. Due to some so-far
	unidentified change in gcc, the stack space used by variables defined
	inside { } is not recovered/re-used when the block ends, so all these
	structs have become additive (this is the same problem worked around
	in commit cf57d345b). Fortunately, these two files could be fixed with
	a single line addition of "static" to the struct definition in the
	macro.

	virnettlscontexttest.c was a bit different, though. The problem structs
	in the do/while loop of macros had non-constant initializers, so it
	took a bit more work and piecemeal initialization instead of member
	initialization to get things to be happy.

	In an ideal world, none of these changes should be necessary, but not
	knowing how long it will be until the gcc regressions are fixed, and
	since the code is just as correct after this patch as before, it makes
	sense to fix libvirt's build for -O0 while also reporting the gcc
	problem.

	test: fix segfault in networkxml2argvtest
	This bug resolves https://bugzilla.redhat.com/show_bug.cgi?id=810100

	rpm builds for i686 were failing with a segfault in
	networkxml2argvtest. Running under valgrind showed that a region of
	memory was being referenced after it had been freed (as the result of
	realloc - see the valgrind report in the BZ).

	The problem (in replaceTokens() - added in commit 22ec60, meaning this
	bug was in 0.9.10 and 0.9.11) was that the pointers token_start and
	token_end were being computed based on the value of *buf, then *buf
	was being realloc'ed (potentially moving it), then token_start and
	token_end were used without recomputing them to account for movement
	of *buf.

	The solution is to change the code so that token_start and token_end
	are offsets into *buf rather than pointers. This way there is only a
	single pointer to the buffer, and nothing needs readjusting after a
	realloc. (You may note that some uses of token_start/token_end didn't
	need to be changed to add in "*buf +" - that's because there ended up
	being a +*buf and -*buf which canceled each other out).

	DV gets the credit for finding this bug and pointing out the valgrind
	report.

	Fix initial hypervisor conditionals
	The openvz, virtualbox and vmware drivers do not run inside
	libvirtd, therefore they should be grouped with the other
	client side drivers

	Remove bogus xen-devel dep from libvirt-devel RPM
	The public libvirt API does not have any application visible
	dependency on Xen libraries. The xen-devel dependency is thus
	bogus

2012-04-04  Daniel P. Berrange  <berrange@redhat.com>

	Introduce per-hypervisor virtual RPMs
	Introduce a set sub-RPMs, one per hypervisor, which can be used
	as dependency targets by applications wishing to pull in the
	full stack of packages required for a specific hypervisor. This
	avoids the application needing to know what the hypervisor specific
	package set is.

	ie, applications should not need to know that using the libvirt
	Xen hypervisor requires the 'xen' RPM - libvirt should take care
	of that knowledge. All the application wants is 'libvirt-daemon-xen'

	There are 5 sub-RPMs:

	  libvirt-daemon-qemu - non-native TCG based emulators
	  libvirt-daemon-kvm  - native KVM hypervisor
	  libvirt-daemon-uml  - User Mode linux
	  libvirt-daemon-xen  - Xen, either via XenD or libxl
	  libvirt-daemon-lxc  - Linux native containers

	When driver modules get turned on, these sub-RPMs will also
	gain dependencies on the appropriate driver module .so files

	 - libvirt-daemon-config-network - the virbr0 config definition
	 - libvirt-daemon-config-nwfilter - the firewall config rules

	For backwards compatibility with existing installs / application RPM
	deps, the 'libvirt' RPM is retained, but will have a dependency on
	the 3 new RPMs.

	qemu: Start nested job in qemuDomainCheckEjectableMedia
	Originally, qemuDomainCheckEjectableMedia was entering monitor with qemu
	driver lock. Commit 2067e31bf97667eab9f111b496f5e9a44e827c5b, which I
	made to fix that, revealed another issue we had (but didn't notice it
	since the driver was locked): we didn't set nested job when
	qemuDomainCheckEjectableMedia is called during migration. Thus the
	original fix I made was wrong.

2012-04-02  Philipp Hahn  <hahn@univention.de>

	Xen: Fix <clock> handling
	XenD-3.1 introduced managed domains. HV-domains have rtc_timeoffset
	(hgd24f37b31030 from 2007-04-03), which tracks the offset between the
	hypervisors clock and the domains RTC, and is persisted by XenD.
	In combination with localtime=1 this had a bug until XenD-3.4
	(hg5d701be7c37b from 2009-04-01) (I'm not 100% sure how that bug
	manifests, but at least for me in TZ=Europe/Berlin I see the previous
	offset relative to utc being applied to localtime again, which manifests
	in an extra hour being added)

	XenD implements the following variants for clock/@offset:
	- PV domains don't have a RTC → 'localtime' | 'utc'
	- <3.1: no managed domains → 'localtime' | 'utc'
	- ≥3.1: the offset is tracked for HV → 'variable'
	        due to the localtime=1 bug → 'localtime' | 'utc'
	- ≥3.4: the offset is tracked for HV → 'variable'

	Current libvirtd still thinks XenD only implements <clock offset='utc'/>
	and <clock offset='localtime'/>, which is wrong, since the semantic of
	'utc' and 'localtime' specifies, that the offset will be reset on
	domain-restart, while with 'variable' the offset is kept. (keeping the
	offset over "virsh edit" is important, since otherwise the clock might
	jump, which confuses certain guest OSs)

	xendConfigVersion was last incremented to 4 by the xen-folks for
	xen-3.1.0. I know of no way to reliably detect the version of XenD
	(user space tools), which may be different from the version of the
	hypervisor (kernel) version! Because of this only the change from
	'utc'/'localtime' to 'variable' in XenD-3.1 is handled, not the buggy
	behaviour of XenD-3.1 until XenD-3.4.

	For backward compatibility with previous versions of libvirt Xen-HV
	still accepts 'utc' and 'localtime', but they are returned as 'variable'
	on the next read-back from Xend to libvirt, since this is what XenD
	implements: The RTC is NOT reset back to the specified time on next
	restart, but the previous offset is kept.
	This behaviour can be turned off by adding the additional attribute
	adjustment='reset', in which case libvirt will report an error instead
	of doing the conversion. The attribute can also be used as a shortcut to
	offset='variable' with basis='...'.

	With these changes, it is also necessary to adjust the xen tests:

	"localtime = 0" is always inserted, because otherwise on updates the
	value is not changed within XenD.

	adjustment='reset' is inserted for all cases, since they're all <
	XEND_CONFIG_VERSION_3_1_0, only 3.1 introduced persistent
	rtc_timeoffset.

	Some statements change their order because code was moved around.

2012-04-02  Philipp Hahn  <hahn@univention.de>

	Support clock=variable relative to localtime
	Since Xen 3.1 the clock=variable semantic is supported. In addition to
	qemu/kvm Xen also knows about a variant where the offset is relative to
	'localtime' instead of 'utc'.

	Extends the libvirt structure with a flag 'basis' to specify, if the
	offset is relative to 'localtime' or 'utc'.

	Extends the libvirt structure with a flag 'reset' to force the reset
	behaviour of 'localtime' and 'utc'; this is needed for backward
	compatibility with previous versions of libvirt, since they report
	incorrect XML.

	Adapt the only user 'qemu' to the new name.
	Extend the RelaxNG schema accordingly.
	Document the new 'basis' attribute in the HTML documentation.
	Adapt test for the new attribute.

	qemu: fix memory leak in virDomainGetVcpus
	https://bugzilla.redhat.com/show_bug.cgi?id=808979

	The leak is really in virProcessInfoGetAffinity, as shown in the
	valgrind output given in the above bug report - it calls CPU_ALLOC(),
	but then fails to call CPU_FREE().

	This leak has existed in every version of libvirt since 0.7.5.

2012-03-31  Eric Blake  <eblake@redhat.com>

	conf: allow fuzz in XML with cur balloon > max
	Commit 1b1402b introduced a regression.  Since older libvirt versions
	would silently round memory up (until the previous patch), but populated
	current memory based on querying the guest, it was possible to have
	dumpxml show cur > max by the amount of the rounding.  For example, if
	a user requested 1048570 KiB memory (just shy of 1GiB), the qemu
	driver would actually run with 1048576 KiB, and libvirt 0.9.10 would
	output a current that was 6KiB larger than the maximum.  Situations
	where this could have an impact include, but are not limited to,
	migration from old to new libvirt, managedsave in old libvirt and
	start in new libvirt, snapshot creation in old libvirt and revert in
	new libvirt - without this patch, the new libvirt would reject the
	VM because of the rounding discrepancy.

	Fix things by adding a fuzz factor, and silently clamp current down to
	maximum in that case, rather than failing to reparse XML for an existing
	VM.  From a practical standpoint, this has no user impact: 'virsh
	dumpxml' will continue to query the running guest rather than rely on
	the incoming xml, which will see the currect current value, and even if
	clamping down occurs during parsing, it will be by at most the fuzz
	factor of a megabyte alignment, and rounded back up when passed back to
	the hypervisor.

	Meanwhile, we continue to reject cur > max if the difference is beyond
	the fuzz factor of nearest megabyte.  But this is not a real change in
	behavior, since with 0.9.10, even though the parser allowed it, later
	in the processing stream we would reject it at the qemu layer; so
	rejecting it in the parser just moves error detection to a nicer place.

	* src/conf/domain_conf.c (virDomainDefParseXML): Don't reject
	existing XML.
	Based on a report by Zhou Peng.

	python: improve conversion validation
	Laszlo Ersek pointed out that in trying to convert a long to an
	unsigned int, we used:

	long long_val = ...;
	if ((unsigned int)long_val == long_val)

	According to C99 integer promotion rules, the if statement is
	equivalent to:

	(unsigned long)(unsigned int)long_val == (unsigned long)long_val

	since you get an unsigned comparison if at least one side is
	unsigned, using the largest rank of the two sides; but on 32-bit
	platforms, where unsigned long and unsigned int are the same size,
	this comparison is always true and ends up converting negative
	long_val into posigive unsigned int values, rather than rejecting
	the negative value as we had originally intended (python longs
	are unbounded size, and we don't want to do silent modulo
	arithmetic when converting to C code).

	Fix this by using direct comparisons, rather than casting.

	Refactor the libvirt RPM daemon pieces
	There are a number of flaws with our packaging of the libvirtd
	daemon:

	 - Installing 'libvirt' does not install 'qemu-kvm' or 'xen'
	   etc which are required to actually run the hypervisor in
	   question
	 - Installing 'libvirt' pulls in the default configuration
	   files which may not be wanted & cause problems if installed
	   inside a guest
	 - It is not possible to explicitly required all the peices
	   required to manage a specific hypervisor

	This change takes the 'libvirt' RPM and and changes it thus

	 - libvirt: just a virtual package with dep on libvirt-daemon,
	   libvirt-daemon-config-network & libvirt-daemon-config-nwfilter
	 - libvirt-daemon: the libvirt daemon and related pieces
	 - libvirt-daemon-config-network: the default network config
	 - libvirt-daemon-config-nwfilter: the network filter configs
	 - libvirt-docs: the website HTML

	We then introduce some more virtual (empty) packages

	 - libvirt-daemon-qemu: Deps on libvirt-daemon & 'qemu'
	 - libvirt-daemon-kvm: Deps on libvirt-daemon & 'qemu-kvm'
	 - libvirt-daemon-lxc: Deps on libvirt-daemon
	 - libvirt-daemon-uml: Deps on libvirt-daemon
	 - libvirt-daemon-xen: Deps on libvirt-daemon & 'xen'

	 - libvirt-qemu: Deps on libvirt-daemon-qemu & libvirt-daemon-config-{network,nwfilter}
	 - libvirt-kvm: Deps on libvirt-daemon-kvm & libvirt-daemon-config-{network,nwfilter}
	 - libvirt-lxc: Deps on libvirt-daemon-lxc & libvirt-daemon-config-{network,nwfilter}
	 - libvirt-uml: Deps on libvirt-daemon-uml & libvirt-daemon-config-{network,nwfilter}
	 - libvirt-xen: Deps on libvirt-daemon-xen & libvirt-daemon-config-network

	My intent in the future is to turn on the driver modules by
	default, at which time 'libvirt-daemon' will cease to include
	any specific drivers, instead we'll get libvirt-daemon-driver-XXXX
	packages for each driver. The libvirt-daemon-XXX packages will
	then pull in each driver that they require.

	It is recommended that applications required a locally installed
	libvirtd daemon, use either 'Requires: libvirt-daemon-XXXX' or
	'Requires: libvirt-XXX' and *not* "Requires: libvirt-daemon"
	or 'Requires: libvirt'

	qemu: support live change of the bridge used by a guest network device
	This patch was created to resolve this upstream bug:

	  https://bugzilla.redhat.com/show_bug.cgi?id=784767

	and is at least a partial solution to this RHEL RFE:

	  https://bugzilla.redhat.com/show_bug.cgi?id=805071

	Previously the only attribute of a network device that could be
	modified by virUpdateDeviceFlags() ("virsh update-device") was the
	link state; attempts to change any other attribute would log an error
	and fail.

	This patch adds recognition of a change in bridge device name, and
	supports reconnecting the guest's interface to the new device.
	Standard audit logs for detaching and attaching a network device are
	also generated. Although the current auditing function doesn't log the
	bridge being attached to, this will later be changed in a separate
	patch.

	qemu: eliminate nested switch, simplify code
	qemuBuildHostNetStr had a switch-within-a-switch where both were
	looking at the same variable. This was apparently to take advantage of
	code common to three different cases (while also taking care of some
	code that was different). However, there were only 2 lines common to
	all, one of those can be eliminated by merging it into the
	virAsprintfs that are in each case. On top of that, all the extra
	empty cases cause Coverity complaints (because they are unreachable),
	but absence of the empty cases causes a compile error due to
	"enumeration value not handled in switch".

	The solution is to just make each toplevel case independent, folding
	in the common code to each.

	Revert "Set default name for SPICE agent channel"

2012-03-31  Laine Stump  <laine@laine.org>

	qemu: set default name for SPICE agent channel when generating command
	commit b0e2bb33 set a default value for the SPICE agent channel by
	inserting it during parsing of the channel XML. That method of setting
	a default is problematic because it makes a format/parse roundtrip
	unclean, and experience with setting other values as a side effect of
	parsing has led to headaches (e.g. automatically setting a MAC address
	in the parser when one isn't specified in the input XML).

	This patch does not revert commit b0e2bb33 (it will be reverted in a
	separate patch) but adds the alternate implementation of simply
	inserting the default value in the appropriate place on the qemu
	commandline when no value is provided.

	Set default name for SPICE agent channel
	libvirt documentation for channels with type 'spicevmc' says that the
	'target' child node has:
	"an optional attribute name controls how the guest will have access
	 to the channel, and defaults to name='com.redhat.spice.0'."

	However, this default value is never set in libvirt code base,
	there's only a check in qemu_command.c to error out if the name
	attribute doesn't have the expected value (if it's set).

	This commit sets a default target name for spicevmc channels during
	the domain configuration parsing so that the code agrees with the

	Enable all warnings permanently & default to -Werror for GIT builds
	Given that we auto-detect whether each -Wxxxx flag is supported by
	GCC, and we are warning-free and use automake silent rules, there
	is no compelling reason to allow compile warnings to be disabled.

	Replace the --enable-compile-warnings flag with a simpler
	--enable-werror flag, which defaults to 'yes' if building
	from GIT, or 'no' if building from tar.gz

	This helps ensure that everyone writing patches for libvirt will
	take care to fix their warning problems before submitting for
	review

	For builds from tar.gz tests will not be built by default. For

	snapshot: don't pass NULL to QMP command creation
	Commit d42a2ff caused a regression in creating a disk-only snapshot
	of a qcow2 disk; by passing the wrong variable to the monitor call,
	libvirt ended up creating JSON that looked like "format":null instead
	of the intended "format":"qcow2".

	To make it easier to diagnose this in the future, make JSON creation
	error out if "s:arg" is paired with NULL (it is still possible to
	use "n:arg" in the rare cases where qemu will accept a null).

	build: fix "missing initializer" error in qemu_process.c
	Found when attempting to build on Fedora 17 alpha with:

	   ./autogen.sh --system --enable-compile-warnings=error

	(this same build command works without problem on Fedora 16). Since
	the consumer of the qemuProcessReconnectData doesn't assume that the
	other fields of the struct are initialized (although it uses them
	internally), the simpler solution is to just switch to C99-style
	struct initialization (which doesn't require specification of all
	fields).

	(this same build command works without problem on Fedora 16). All

	build: avoid frame size error when building without -O2
	libvirt always adds -Werror-frame-larger-than=4096 to the flags when
	it builds. When building on Fedora 17, two functions with multiple
	1024 buffers declared inside if {} blocks would generate frame size
	errors; apparently the version of gcc on Fedora 16 will merge these
	multiple buffers into a single buffer even when optimization is off,
	but Fedora 17 won't.

	The fix is to declare a single 1024 buffer at the top of the two
	offending functions, and reuse the single buffer throughout the
	functions.

	Added syntax-check rule for return with parentheses
	After cleanup introduced with previous commit, there is a need for

	parameter is taken from the cleanup commit and modified so it fits
	'grep -E' format. Semicolon at the end is needed, otherwise the regexp
	could match return with cast.

	Cleanup for a return statement in source files
	Return statements with parameter enclosed in parentheses were modified
	and parentheses were removed. The whole change was scripted, here is how:

	List of files was obtained using this command:
	git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
	grep -e '\.[ch]$' -e '\.py$'

	Found files were modified with this command:
	sed -i -e                                                                 \
	's_^\(.*\<return\)\s*(\(\([^()]*([^()]*)[^()]*\)*\))\s*\(;.*$\)_\1 \2\4_' \
	-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

	Then checked for nonsense.

	The whole command looks like this:
	git grep -l -e '\<return\s*([^()]*\(([^()]*)[^()]*\)*)\s*;' |             \
	grep -e '\.[ch]$' -e '\.py$' | xargs sed -i -e                            \

	snapshot: improve qemu handling of reused snapshot targets
	The oVirt developers have stated that the real reasons they want
	to have qemu reuse existing volumes when creating a snapshot are:
	1. the management framework is set up so that creation has to be
	done from a central node for proper resource tracking, and having
	libvirt and/or qemu create things violates the framework, and
	2. qemu defaults to creating snapshots with an absolute path to
	the backing file, but oVirt wants to manage a backing chain that
	uses just relative names, to allow for easier migration of a chain
	across storage locations.

	When 0.9.10 added VIR_DOMAIN_SNAPSHOT_CREATE_REUSE_EXT (commit
	4e9953a4), it only addressed point 1, but libvirt was still using
	O_TRUNC which violates point 2.  Meanwhile, the new qemu
	'transaction' monitor command includes a new optional mode argument
	that will force qemu to reuse the metadata of the file it just
	opened (with the burden on the caller to have valid metadata there
	in the first place).  So, this tweaks the meaning of the flag to
	cover both points as intended for use by oVirt.  It is not strictly
	backward-compatible to 0.9.10 behavior, but it can be argued that
	the O_TRUNC of 0.9.10 was a bug.

	Note that this flag is all-or-nothing, and only selects between
	'existing' and the default 'absolute-paths'.  A more flexible
	approach that would allow per-disk selections, as well as adding
	support for the 'no-backing-file' mode, would be possible by
	extending the <domainsnapshot> xml to have a per-disk mode, but
	until we have a management application expressing a need for that
	additional complexity, it is not worth doing.

	* src/libvirt.c (virDomainSnapshotCreateXML): Tweak documentation.
	* src/qemu/qemu_monitor.h (qemuMonitorDiskSnapshot): Add
	parameters.
	* src/qemu/qemu_monitor_json.h (qemuMonitorJSONDiskSnapshot):

	snapshot: wire up qemu transaction command

	snapshot: add support for qemu transaction command
	QEmu 1.1 is adding a 'transaction' command to the JSON monitor.
	Each element of a transaction corresponds to a top-level command,
	with the additional guarantee that the transaction flushes all
	pending I/O, then guarantees that all actions will be successful
	as a group or that failure will roll back the state to what it
	was before the monitor command.  The difference between a
	top-level command:

	{ "execute": "blockdev-snapshot-sync", "arguments":
	  { "device": "virtio0", ... } }

	and a transaction:

	{ "execute": "transaction", "arguments":
	  { "actions": [
	    { "type": "blockdev-snapshot-sync", "data":
	      { "device": "virtio0", ... } } ] } }

	is just a couple of changed key names and nesting the shorter
	command inside a JSON array to the longer command.  This patch
	just adds the framework; the next patch will actually use a
	transaction.

	* src/qemu/qemu_monitor_json.c (qemuMonitorJSONMakeCommand): Move
	guts...
	(qemuMonitorJSONMakeCommandRaw): ...into new helper.  Add support

	snapshot: rudimentary qemu support for atomic disk snapshot
	Taking an external snapshot of just one disk is atomic, without having
	to pause and resume the VM.  This also paves the way for later patches
	to interact with the new qemu 'transaction' monitor command.

	The various scenarios when requesting atomic are:
	online, 1 disk, old qemu - safe, allowed by this patch
	online, more than 1 disk, old qemu - failure, this patch
	offline snapshot - safe, once a future patch implements offline disk snapshot
	online, 1 or more disks, new qemu - safe, once future patch uses transaction

	Taking an online system checkpoint snapshot is atomic, since it is
	done via a single 'savevm' monitor command.  Taking an offline system
	checkpoint snapshot is atomic, thanks to the previous patch.

	* src/qemu/qemu_driver.c (qemuDomainSnapshotCreateXML): Support
	new flag for single-disk setups.
	(qemuDomainSnapshotDiskPrepare): Check for atomic here.
	(qemuDomainSnapshotCreateDiskActive): Skip pausing the VM when

	(qemuDomainSnapshotIsAllowed): Use bool instead of int.

	(qemuDomainSnapshotForEachQcow2Raw): ...to new helper, to allow

2012-03-24  Eric Blake  <eblake@redhat.com>

	snapshot: add atomic create flag
	Right now, it is appallingly easy to cause qemu disk snapshots
	to alter a domain then fail; for example, by requesting a two-disk
	snapshot where the second disk name resides on read-only storage.
	In this failure scenario, libvirt reports failure, but modifies
	the live domain XML in-place to record that the first disk snapshot
	was taken; and places a difficult burden on the management app
	to grab the XML and reparse it to see which disks, if any, were
	altered by the partial snapshot.

	This patch adds a new flag where implementations can request that
	the hypervisor make snapshots atomically; either no changes to
	XML occur, or all disks were altered as a group.  If you request
	the flag, you either get outright failure up front, or you take
	advantage of hypervisor abilities to make an atomic snapshot. Of
	course, drivers should prefer the atomic means even without the
	flag explicitly requested.

	There's no way to make snapshots 100% bulletproof - even if the
	hypervisor does it perfectly atomic, we could run out of memory
	during the followup tasks of updating our in-memory XML, and report
	a failure.  However, these sorts of catastrophic failures are rare
	and unlikely, and it is still nicer to know that either all
	snapshots happened or none of them, as that is an easier state to
	recover from.

	Add support for event tray moved of removable disks
	This patch introduces a new event type for the QMP event
	DEVICE_TRAY_MOVED, which occurs when the tray of a removable
	disk is moved (i.e opened or closed):

	    VIR_DOMAIN_EVENT_ID_TRAY_CHANGE

	The event's data includes the device alias and the reason
	for tray status' changing, which indicates why the tray
	status was changed. Thus the callback definition for the event
	is:

	enum {
	    VIR_DOMAIN_EVENT_TRAY_CHANGE_OPEN = 0,
	    VIR_DOMAIN_EVENT_TRAY_CHANGE_CLOSE,

	\#ifdef VIR_ENUM_SENTINELS
	    VIR_DOMAIN_EVENT_TRAY_CHANGE_LAST
	\#endif
	} virDomainEventTrayChangeReason;

	typedef void
	(*virConnectDomainEventTrayChangeCallback)(virConnectPtr conn,
	                                           virDomainPtr dom,
	                                           const char *devAlias,

	qemu: Avoid dangling migration-out job when client dies
	When a client which started non-p2p migration dies in a bad time, the
	source libvirtd never clears the migration job and almost nothing can be
	done with the domain without restarting the daemon. This patch makes use
	of connection close callbacks and ensures that migration job is properly
	discarded when the client disconnects.

	qemu: Make autodestroy utilize connection close callbacks

	qemu: Add connection close callbacks
	Add support for registering arbitrary callback to be called for a domain
	when a connection gets closed.

	qemu: Avoid dangling migration-in job on shutoff domains
	Destination daemon should not rely on the client or source daemon
	(depending on the type of migration) to call Finish when migration
	fails, because the client may crash before it can do so. The domain
	prepared for incoming migration is set to be destroyed (and migration
	job cleaned up) when connection with the client closes but this is not
	enough. If the associated qemu process crashes after Prepare step and
	the domain is cleaned up before the connection gets closed, autodestroy
	is not called for the domain and migration jobs remains set. In case the
	domain is defined on destination host (i.e., it is not completely
	removed once destroyed) we keep the job set for ever. To fix this, we
	register a cleanup callback which is responsible to clean migration-in
	job when a domain dies anywhere between Prepare and Finish steps. Note
	that we can't blindly clean any job when spotting EOF on monitor since
	normally an API is running at that time.

	qemu: Add support for domain cleanup callbacks
	Add support for registering cleanup callbacks to be run when a domain
	transitions to shutoff state.

	qemu: Use unlimited speed when migrating to file
	This reverts commit 61f2b6ba5fdef0613d6351b99913b5ef468144ce and most of
	commit d8916dc8e2f612ab3ce46f32c4bfeb0bd73f6007, which effectively
	brings back commit ef1065cf5acad13767c054758cbe7f4e8af5d241 written by
	Jim Fehlig:

	The qemu migration speed default is 32MiB/s as defined in migration.c

	/* Migration speed throttling */
	static int64_t max_throttle = (32 << 20);

	There's no need to throttle migration when targeting a file, so set
	migration speed to unlimited prior to migration, and restore to libvirt
	default value after migration.

	Default units is MB for migrate_set_speed monitor command, so
	(INT64_MAX / (1024 * 1024)) is used for unlimited migration speed.

	This was reverted because migration to file could not be canceled and
	even monitored since qemu was not processing any monitor commands until
	the migration finished. This is now different as we make sure the
	file descriptor we pass to qemu is able to properly report EAGAIN.
	Recent qemu changes might have helped as well.

	I tested managedsave with this patch in and indeed, it is 10x faster
	while I can still monitor its progress.

	conf: forbid use of multicast mac addresses
	A few times libvirt users manually setting mac addresses have
	complained of a networking failure that ends up being due to a multicast
	mac address being used for a guest interface. This patch prevents that
	by logging an error and failing if a multicast mac address is
	encountered in each of the three following cases:

	1) domain xml <interface> mac address.
	2) network xml bridge mac address.
	3) network xml dhcp/host mac address.

	There are several other places where a mac address can be input that
	aren't controlled in this manner because failure to do so has no
	consequences (e.g., if the address will be used to search through
	existing interfaces for a match).

	The RNG has been updated to add multiMacAddr and uniMacAddr along with
	the existing macAddr, and macAddr was switched to uniMacAddr where
	appropriate.

	conf: return immediately on error in dhcp host element
	If an error was encountered parsing a dhcp host entry mac address or

	This patch returns immediately on logging the first error.

	util: fail attempts to use same mac address for guest and tap
	This patch is in response to:

	  https://bugzilla.redhat.com/show_bug.cgi?id=798467

	If a guest's tap device is created using the same MAC address the
	guest uses for its own network card (which connects to the tap
	device), the Linux kernel will log the following message and traffic
	will not pass:

	 kernel: vnet9: received packet with own address as source address

	This patch disallows MAC addresses with a first byte of 0xFE, but only in
	the case that the MAC address is used for a guest interface that's
	connected by way of a standard tap device. (In other words, the
	validation is done at runtime at the same place the MAC address is
	modified for the tap device, rather than when mac address is parsed,
	the idea being that it is then we know for sure the address will be
	problematic.)

	snapshot: make quiesce a bit safer
	If a guest is paused, we were silently ignoring the quiesce flag,
	which results in unclean snapshots, contrary to the intent of the
	flag.  Since we can't quiesce without guest agent support, we should
	instead fail if the guest is not running.

	Meanwhile, if we attempt a quiesce command, but the guest agent
	doesn't respond, and we time out, we may have left the command
	pending on the guest's queue, and when the guest resumes parsing
	commands, it will freeze even though our command is no longer
	around to issue a thaw.  To be safe, we must _always_ pair every
	quiesce call with a counterpart thaw, even if the quiesce call
	failed due to a timeout, so that if a guest wakes up and starts
	processing a command backlog, it will not get stuck in a frozen
	state.

	Always issue thaw after a quiesce, even if quiesce failed.

	A common coding pattern for changing blkio parameters is

	For this to work, it must be possible to roundtrip through

	qemu: Support numad
	numad is an user-level daemon that monitors NUMA topology and
	processes resource consumption to facilitate good NUMA resource
	alignment of applications/virtual machines to improve performance
	and minimize cost of remote memory latencies. It provides a
	pre-placement advisory interface, so significant processes can
	be pre-bound to nodes with sufficient available resources.

	More details: http://fedoraproject.org/wiki/Features/numad

	"numad -w ncpus:memory_amount" is the advisory interface numad
	provides currently.

	This patch add the support by introducing a new XML attribute
	for <vcpu>. e.g.

	  <vcpu placement="auto">4</vcpu>
	  <vcpu placement="static" cpuset="1-10^6">4</vcpu>

	The returned advisory nodeset from numad will be printed
	in domain's dumped XML. e.g.
	  <vcpu placement="auto" cpuset="1-10^6">4</vcpu>

	If placement is "auto", the number of vcpus and the current
	memory amount specified in domain XML will be used for numad
	command line (numad uses MB for memory amount):
	  numad -w $num_of_vcpus:$current_memory_amount / 1024

	The advisory nodeset returned from numad will be used to set
	domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity).

	If the user specifies both CPU affinity policy (e.g.
	(<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto"
	the specified CPU affinity will be overridden.

	Only QEMU/KVM drivers support it now.

	See docs update in patch for more details.

	In qemuDomainDetachNetDevice, detach was being used before it had been

	dereference of a NULL pointer.

	This behavior was a regression introduced in commit

	qemu: eliminate memory leak in qemuDomainUpdateDeviceConfig
	This function was freeing a virDomainNetDef with

	qemu: support persistent hotplug of <hostdev> devices

	qemuDomainAttachDeviceConfig and qemuDomainDetachDeviceConfig.

2012-03-09  Laine Stump  <laine@laine.org>

	util: standardize return from functions calling virNetlinkCommand
	There are several functions that call virNetlinkCommand, and they all
	follow a common pattern, with three exit labels: err_exit (or
	cleanup), malformed_resp, and buffer_too_small. All three of these
	labels do their own cleanup and have their own return. However, the
	malformed_resp label usually frees the same items as the
	cleanup/err_exit label, and the buffer_too_small label just doesn't
	free recvbuf (because it's known to always be NULL at the time we goto
	buffer_too_small.

	In order to simplify and standardize the code, I've made the following
	changes to all of these functions:

	1) err_exit is replaced with the more libvirt-ish "cleanup", which
	   makes sense because in all cases this code is also executed in the
	   case of success, so labelling it err_exit may be confusing.

	2) rc is initialized to -1, and set to 0 just before the cleanup
	   label. Any code that currently sets rc = -1 is made to instead goto
	   cleanup.

	3) malformed_resp and buffer_too_small just log their error and goto
	   cleanup. This gives us a single return path, and a single place to
	   free up resources.

	4) In one instance, rather then logging an error immediately, a char*
	   msg was pointed to an error string, then goto cleanup (and cleanup
	   would log an error if msg != NULL). It takes no more lines of code
	   to just log the message as we encounter it.

	This patch should have 0 functional effects.

	util: eliminate device object leaks related to virDomain*Remove*()
	There are several functions in domain_conf.c that remove a device
	object from the domain's list of that object type, but don't free the
	object or return it to the caller to free. In many cases this isn't a
	problem because the caller already had a pointer to the object and
	frees it afterward, but in several cases the removed object was just
	left floating around with no references to it.

	In particular, the function qemuDomainDetachDeviceConfig() calls
	functions to locate and remove net (virDomainNetRemoveByMac), disk
	(virDomainDiskRemoveByName()), and lease (virDomainLeaseRemove())
	devices, but neither it nor its caller qemuDomainModifyDeviceConfig()
	ever obtain a pointer to the device being removed, much less free it.

	This patch modifies the following "remove" functions to return a
	pointer to the device object being removed from the domain device
	arrays, to give the caller the option of freeing the device object
	using that pointer if needed. In places where the object was
	previously leaked, it is now freed:

	  virDomainDiskRemove
	  virDomainDiskRemoveByName
	  virDomainNetRemove
	  virDomainNetRemoveByMac
	  virDomainHostdevRemove
	  virDomainLeaseRemove
	  virDomainLeaseRemoveAt

	The functions that had been leaking:

	  libxlDomainDetachConfig - leaked a virDomainDiskDef
	  qemuDomainDetachDeviceConfig - could leak a virDomainDiskDef,
	                            a virDomainNetDef, or a
	                            virDomainLeaseDef
	  qemuDomainDetachLease   - leaked a virDomainLeaseDef

2012-03-09  Laine Stump  <laine@laine.org>

	qemu: don't 'remove' hostdev objects from domain if operation fails
	There were certain paths through the hostdev detach code that could
	lead to the lower level function failing (and not removing the object
	from the domain's hostdevs list), but the higher level function
	free'ing the hostdev object anyway. This would leave a stale
	hostdevdef pointer in the list, which would surely cause a problem
	eventually.

	This patch relocates virDomainHostdevRemove from the lower level
	functions qemuDomainDetachThisHostDevice and
	qemuDomainDetachHostPciDevice, to their caller
	qemuDomainDetachThisHostDevice, placing it just before the call to
	virDomainHostdevDefFree. This makes it easy to verify that either both
	operations are done, or neither.

	NB: The "dangling pointer" part of this problem was introduced in
	commit 13d5a6, so it is not present in libvirt versions prior to
	0.9.9. Earlier versions would return failure in certain cases even
	though the the device object was removed/deleted, but the removal and
	deletion operations would always both happen or neither.

	util: consolidate duplicated error messages in virnetlink.c
	There are special stub versions of all public functions in this file
	that are compiled when either libnl isn't available or the platform
	isn't linux. Each of these functions had two almost identical message,
	differing only in the function name included in the message. Since log
	messages already contain the function name, we can just define a const
	char* with the common part of the string, and use that same string for
	all the log messages.

	Also, rather than doing #if defined ... #else ... #endif *inside the
	error log macro invocation*, this patch does #if defined ... just
	once, using it to decide which single string to define. This turns the
	error log in each function from 6 lines, to 1 line.

	qemu: Don't parse device twice in attach/detach
	Some members are generated during XML parse (e.g. MAC address of

	This is wrong then as the second time we are not guaranteed

	xml: use long long internally, to centralize overflow checks
	On 64-bit platforms, unsigned long and unsigned long long are
	identical, so we don't have to worry about overflow checks.
	On 32-bit platforms, anywhere we narrow unsigned long long back
	to unsigned long, we have to worry about overflow; it's easier
	to do this in one place by having most of the code use the same
	or wider types, and only doing the narrowing at the last minute.
	Therefore, the memory set commands remain unsigned long, and
	the memory get command now centralizes the overflow check into
	libvirt.c, so that drivers don't have to repeat the work.

	xml: drop unenforced minimum memory limit from RNG
	The test domain allows <memory>0</memory>, but the RNG was stating

	storage: support more scaling suffixes
	Disk manufacturers are fond of quoting sizes in powers of 10,
	rather than powers of 2 (after all, 2.1 GB sounds larger than
	2.0 GiB, even though the exact opposite is true).  So, we might
	as well follow coreutils' lead in supporting three types of
	suffix: single letter ${u} (which we already had) and ${u}iB
	for the power of 2, and ${u}B for power of 10.

	Additionally, it is impossible to create a file with more than
	2**63 bytes, since off_t is signed (if you have enough storage
	to even create one 8EiB file, I'm jealous).  This now reports
	failure up front rather than down the road when the kernel
	finally refuses an impossible size.

	xml: output memory unit for clarity
	Make it obvious to 'dumpxml' readers what unit we are using,
	since our default of KiB for memory (1024) differs from qemu's
	default of MiB; and differs from our use of bytes for storage.

	Tests were updated via:

	$ find tests/*data tests/*out -name '*.xml' | \
	  xargs sed -i 's/<\(memory\|currentMemory\|hard_limit\|soft_limit\|min_guarantee\|swap_hard_limit\)>/<\1 unit='"'KiB'>/"
	$ find tests/*data tests/*out -name '*.xml' | \
	  xargs sed -i 's/<\(capacity\|allocation\|available\)>/<\1 unit='"'bytes'>/"

	followed by a few fixes for the stragglers.

	Note that with this patch, the RNG for <memory> still forbids
	validation of anything except unit='KiB', since the code silently
	ignores the attribute; a later patch will expand <memory> to allow
	scaled input in the code and update the RNG to match.

	xml: share 'unit' in RNG
	The code supported unit='E' for "exabyte", but the RNG did not;
	conversely, the RNG supported "z" and "y" but the code did not
	(I'm jealous if you have that much storage, particularly since
	it won't fit in 64-bit off_t).  Also, the code supported
	<allocation unit='...'>, but not the RNG.

	In an effort to make 'unit' more worthwhile in future patches,
	it's easier to share it between files.

	In making this factorization, note that absFilePath is more
	permissive than 'path', so storage pools and storage volumes
	will now validate with a wider set of file names than before.

	rpc: allow truncated return for virDomainGetCPUStats
	The RPC code assumed that the array returned by the driver would be
	fully populated; that is, ncpus on entry resulted in ncpus * return
	value on exit.  However, while we don't support holes in the middle
	of ncpus, we do want to permit the case of ncpus on entry being
	longer than the array returned by the driver (that is, it should be
	safe for the caller to pass ncpus=128 on entry, and the driver will
	stop populating the array when it hits max_id).

	Additionally, a successful return implies that the caller will then
	use virTypedParamArrayClear on the entire array; for this to not
	free uninitialized memory, the driver must ensure that all skipped
	entries are explicitly zeroed (the RPC driver did this, but not
	the qemu driver).

	There are now three cases:
	server 0.9.10 and client 0.9.10 or newer: No impact - there were no
	hypervisor drivers that supported cpu stats

	server 0.9.11 or newer and client 0.9.10: if the client calls with
	ncpus beyond the max, then the rpc call will fail on the client side
	and disconnect the client, but the server is no worse for the wear

	server 0.9.11 or newer and client 0.9.11: the server can return a
	truncated array and the client will do just fine

	I reproduced the problem by using a host with 2 CPUs, and doing:
	virsh cpu-stats $dom --start 1 --count 2

	qemu: install port profile and mac address on netdev hostdevs
	These changes are applied only if the hostdev has a parent net device
	(i.e. if it was defined as "<interface type='hostdev'>" rather than
	just "<hostdev>").  If the parent netdevice has virtual port
	information, the original virtualport associate functions are called
	(these set and restore both mac and port profile on an
	interface). Otherwise, only mac address is set on the device.

	Note that This is only supported for SR-IOV Virtual Functions (not for
	standard PCI or USB netdevs), and virtualport association is only
	supported for 802.1Qbh. For all other types of cards and types of
	virtualport, a "Config Unsupported" error is returned and the

	 - Adds a vf argument to all port profile functions.

	For 802.1Qbh devices, the port profile calls can use a vf argument if
	passed by the caller. If the vf argument is -1 it will try to derive the vf
	if the device passed is a virtual function.

	For 802.1Qbg devices, This patch introduces a null check for the device
	argument because during port profile assignment on a hostdev, this argument
	can be null.

	qemu: support type=hostdev network device live hotplug attach/detach
	qemuDomainAttachNetDevice

	  - re-ordered some things at start of function because
	    networkAllocateActualDevice should always be run and a slot
	    in def->nets always allocated, but host_net_add isn't needed
	    if the actual type is hostdev.

	  - if actual type is hostdev, defer to
	    qemuDomainAttachHostDevice (which will reach up to the NetDef
	    for things like MAC address when necessary). After return
	    from qemuDomainAttachHostDevice, slip directly to cleanup,
	    since the rest of the function is specific to emulated net
	    devices.

	  - put assignment of new NetDef into expanded def->nets down
	    below cleanup: (but only on success) since it is also needed
	    for emulated and hostdev net devices.

	qemuDomainDetachHostDevice

	  - after locating the exact device to detach, check if it's a
	    network device and, if so, use toplevel
	    qemuDomainDetachNetDevice instead so that the def->nets list
	    is properly updated, and 'actual device' properly returned to
	    network pool if appropriate. Otherwise, for normal hostdevs,
	    call the lower level qemuDomainDetachThisDevice.

	qemuDomainDetachNetDevice

	  - This is where it gets a bit tricky. After locating the device
	    on the def->nets list, if the network device type == hostdev,
	    call the *lower level* qemuDomainDetachThisDevice (which will
	    reach back up to the parent net device for MAC address /
	    virtualport when appropriate, then clear the device out of
	    def->hostdevs) before skipping past all the emulated
	    net-device-specific code to cleanup:, where the network
	    device is removed from def->nets, and the network device
	    object is freed.

	In short, any time a hostdev-type network device is detached, we must
	go through the toplevel virDomaineDetachNetDevice function first and
	last, to make sure 1) the def->nnets list is properly managed, and 2)
	any device allocated with networkAllocateActualDevice is properly
	freed. At the same time, in the middle we need to go through the
	lower-level vidDomainDetach*This*HostDevice to be sure that 1) the
	def->hostdevs list is properly managed, 2) the PCI device is properly
	detached from the guest and reattached to the host (if appropriate),
	and 3) any higher level teardown is called at the appropriate time, by
	reaching back up to the NetDef config (part (3) will be covered in a
	separate patch).

	qemu: support type='hostdev' network devices at domain start
	This patch makes sure that each network device ("interface") of
	type='hostdev' appears on both the hostdevs list and the nets list of
	the virDomainDef, and it modifies the qemu driver startup code so that
	these devices will be presented to qemu on the commandline as hostdevs
	rather than as network devices.

	It does not add support for hotplug of these type of devices, or code
	to honor the <mac address> or <virtualport> given in the config (both
	of those will be done in separate patches).

	Once each device is placed on both lists, much of what this patch does
	is modify places in the code that traverse all the device lists so
	that these hybrid devices are only acted on once - either along with
	the other hostdevs, or along with the other network interfaces. (In
	many cases, only one of the lists is traversed / a specific operation
	is performed on only one type of device. In those instances, the code
	can remain unchanged.)

	There is one special case - when building the commandline, interfaces
	are allowed to proceed all the way through
	networkAllocateActualDevice() before deciding to skip the rest of
	netdev-specific processing - this is so that (once we have support for
	networks with pools of hostdev devices) we can get the actual device
	allocated, then rely on the loop processing all hostdevs to generate
	the correct commandline.

	(NB: <interface type='hostdev'> is only supported for PCI network
	devices that are SR-IOV Virtual Functions (VF). Standard PCI[e] and
	USB devices, and even the Physical Functions (PF) of SR-IOV devices
	can only be assigned to a guest using the more basic <hostdev> device
	entry. This limitation is mostly due to the fact that non-SR-IOV
	ethernet devices tend to lose mac address configuration whenever the
	card is reset, which happens when a card is assigned to a guest;
	SR-IOV VFs fortunately don't suffer the same problem.)

	of the syntax:

	    <address type='pci' domain='0' bus='0' slot='7' function='0'/>
	  </interface>

	This would assign the PCI card from bus 0 slot 4 function 3 on the
	host, to bus 0 slot 7 function 0 on the guest, but would first set the
	MAC address of the card to 00:11:22:33:44:55.

	NB: The parser and formatter don't care if the PCI card being
	specified is a standard single function network adapter, or a virtual
	function (VF) of an SR-IOV capable network adapter, but the upcoming
	code that implements the back end of this config will work *only* with
	SR-IOV VFs. This is because modifying the mac address of a standard
	network adapter prior to assigning it to a guest is pointless - part
	of the device reset that occurs during that process will reset the MAC
	address to the value programmed into the card's firmware.

	Although it's not supported by any of libvirt's hypervisor drivers,
	usb network hostdevs are also supported in the parser and formatter
	for completeness and consistency. <source> syntax is identical to that
	for plain <hostdev> devices, except that the <address> element should
	have "type='usb'" added if bus/device are specified:

	  <interface type='hostdev'>
	    <source>
	      <address type='usb' bus='0' device='4'/>
	    </source>
	    <mac address='00:11:22:33:44:55'/>
	  </interface>

	If the vendor/product form of usb specification is used, type='usb'
	is implied:

	  <interface type='hostdev'>
	    <source>
	      <vendor id='0x0012'/>
	      <product id='0x24dd'/>
	    </source>
	    <mac address='00:11:22:33:44:55'/>
	  </interface>

	Again, the upcoming patch to fill in the backend of this functionality
	will log an error and fail with "Unsupported Config" if you actually
	try to assign a USB network adapter to a guest using <interface
	type='hostdev'> - just use a standard <hostdev> entry in that case
	(and also for single-port PCI adapters).

	qemu: refactor hotplug detach of hostdevs
	This refactoring is necessary to support hotplug detach of
	type=hostdev network devices, but needs to be in a separate patch to
	make potential debugging of regressions more practical.

	Rather than the lowest level functions searching for a matching
	device, the search is now done in the toplevel function, and an
	intermediate-level function (qemuDomainDetachThisHostDevice()), which
	expects that the device's entry is already found, is called (this
	intermediate function will be called by qemuDomainDetachNetDevice() in
	order to support detach of type=hostdev net devices)

	This patch should result in 0 differences in functionality.

	conf: hostdev utility functions
	Three new functions useful in other files:

	virDomainHostdevInsert:

	Add a new hostdev at the end of the array. This would more sensibly be
	called virDomainHostdevAppend, but the existing functions for other
	types of devices are called Insert.

	virDomainHostdevRemove:

	Eliminates one entry from the hostdevs array, but doesn't free it;
	patterned after the code at the end of the two
	qemuDomainDetachHostXXXDevice functions (and also other pre-existing
	virDomainXXXRemove functions for other device types).

	virDomainHostdevFind:

	This function is patterned from the search loops at the top of
	qemuDomainDetachHostPciDevice and qemuDomainDetachHostUsbDevice, and
	will be used to re-factor those (and other detach-related) functions.

2012-03-06  Laine Stump  <laine@laine.org>

	conf: put subsys part of virDomainHostdevDef into its own struct
	To shorten some new code that accesses the many fields within the
	subsys struct of a hostdev, create a separate toplevel, typedefed
	virDomainHostdevSubsys struct so that we can define temporary pointers
	to the subsys part.

2012-03-06  Laine Stump  <laine@laine.org>

	conf: give each hostdevdef a parent pointer
	The parent can be any type of device. It defaults to type=none, and a
	NULL pointer. The intent is that if a hostdevdef is contained in the
	def for a higher level device (e.g. virDomainNetDef), hostdev->parent
	will point to the higher level device, and type will be set to that
	type of device. This way, during attach and detach of the device,
	parent can be checked, and appropriate callouts made to do higher
	level device initialization (e.g. setting MAC address).

	Also, although these hostdevs with parents will be added to a domain's
	hostdevs list, they will be treated slightly differently when
	traversing the list, e.g. virDomainHostdefDefFree for a hostdev that
	has a parent doesn't need to be called (and will be a NOP); it will
	simply be removed from the list (since the parent device object is in
	its own type-specific list, and will be freed from there).

2012-03-06  Laine Stump  <laine@laine.org>

	conf: HostdevDef parse/format helper functions
	In an upcoming patch, virDomainNetDef will acquire a
	virDomainHostdevDef, and the <interface> XML will take on some of the
	elements of a <hostdev>. To avoid duplicating the code for parsing and
	formatting the <source> element (which will be nearly identical in
	these two cases), this patch factors those parts out of the
	HostdevDef's parse and format functions, and puts them into separate
	helper functions that are now called by the HostdevDef
	parser/formatter, and will soon be called by the NetDef
	parser/formatter.

	One change in behavior - previously virDomainHostdevDefParseXML() had
	diverged from current common coding practice by logging an error and
	failing if it found any subelements of <hostdev> other than those it
	understood (standard libvirt practice is to ignore/discard unknown
	elements and attributes during parse). The new helper function ignores
	unknown elements, and thus so does the new
	virDomainHostdevDefParseXML.

2012-03-06  Laine Stump  <laine@laine.org>

	conf: make hostdev info a separate object
	In order to allow for a virDomainHostdevDef that uses the
	virDomainDeviceInfo of a "higher level" device (such as a
	virDomainNetDef), this patch changes the virDomainDeviceInfo in the
	HostdevDef into a virDomainDeviceInfoPtr. Rather than adding checks
	all over the code to check for a null info, we just guarantee that it
	is always valid. The new function virDomainHostdevDefAlloc() allocates
	a virDomainDeviceInfo and plugs it in, and virDomainHostdevDefFree()
	makes sure it is freed.

	There were 4 places allocating virDomainHostdevDefs, all of them
	parsers of one sort or another, and those have all had their
	VIR_ALLOC(hostdev) changed to virDomainHostdevDefAlloc(). Other than
	that, and the new functions, all the rest of the changes are just
	mechanical removals of "&" or changing "." to "->".

2012-03-06  Laine Stump  <laine@laine.org>

	conf: add device pointer to args of virDomainDeviceInfoIterate callback
	There will be cases where the iterator callback will need to know the
	type of the device whose info is being operated on, and possibly even
	need to use some of the device's config. This patch adds a
	virDomainDeviceDefPtr to the args of every callback, and fills it in
	appropriately as the devices are iterated through.

	qemu: rename virDomainDeviceInfoPtr variables to avoid confusion
	The virDomainDeviceInfoPtrs in qemuCollectPCIAddress and

	will be changed (in order to match a change in the args sent to
	virDomainDeviceInfoIterate() callback args) to contain a
	virDomainDeviceDefPtr device.

	This patch renames "dev" to "info" (and "dev[n]" to "info[n]") to
	avoid later confusion.

2012-03-06  Laine Stump  <laine@laine.org>

	conf: relocate virDomainDeviceDef and virDomainHostdevDef
	This patch is only code movement + adding some forward definitions of
	typedefs.

	virDomainHostdevDef (not just a pointer to it, but an actual object)
	will be needed in virDomainNetDef and virDomainActualNetDef, so it
	must be relocated earlier in the file.

	Likewise, virDomainDeviceDef will be needed in virDomainHostdevDef, so
	it must be moved up even earlier. This, in turn, creates a forward
	reference problem, but fortunately only with pointers to other device
	types, so their typedefs can be moved up in the file, eliminating the
	problem.

2012-03-06  Laine Stump  <laine@laine.org>

	conf: add missing device types to virDomainDevice(Type|Def)
	Not all device types were represented in virDomainDeviceType, so some
	types of devices couldn't be represented in a virDomainDeviceDef
	(which requires a different type of pointer in the union for each
	different kind of device).

	Since serial, parallel, channel, and console devices are all
	virDomainChrDef, and the virDomainDeviceType is never used to produce
	a string from the type (and only used in the other direction
	internally to code, never to produce XML), I only added one "CHR"
	type, which is associated with "virDomainChrDefPtr chr" in the union.

	util: eliminate crash in virNetDevMacVLanCreateWithVPortProfile
	Commit 723d5c (added after the release of 0.9.10) adds a
	NetlinkEventClient for each interface sent to
	virNetDevMacVLanCreateWithVPortProfile. This should only be done if
	the interface actually *has* a virtPortProfile, otherwise the event
	handler would be a NOP. The bigger problem is that part of the setup
	to create the NetlinkEventClient is to do a memcpy of virtPortProfile
	- if it's NULL, this triggers a segv.

	This patch just qualifies the code that adds the client - if
	virtPortProfile is NULL, it's skipped.

	Parallel shutdown has a configurable parameter PARALLEL_SHUTDOWN that

	util: combine bools in virNetDevTapCreateInBridgePort into flags
	With an additional new bool added to determine whether or not to

	virNetDevTapCreateInBridgePort had three booleans (well, 2 bools and
	an int used as a bool) in the arg list, which made it increasingly
	difficult to follow what was going on. This patch combines those three
	into a single flags arg, which not only shortens the arg list, but

	util: centralize tap device MAC address 1st byte "0xFE" modification
	When a tap device for a domain is created and attached to a bridge,
	the first byte of the tap device MAC address is set to 0xFE, while the
	rest is set to match the MAC address that will be presented to the
	guest as its network device MAC address. Setting this high value in
	the tap's MAC address discourages the bridge from using the tap
	device's MAC address as the bridge's own MAC address (Linux bridges
	always take on the lowest numbered MAC address of all attached devices
	as their own).

	In one case within libvirt, a tap device is created and attached to
	the bridge with the intent that its MAC address be taken on by the
	bridge as its own (this is used to assure that the bridge has a fixed
	MAC address to prevent network outages created by the bridge MAC
	address "flapping" as guests are started and stopped). In this case,
	the first byte of the mac address is *not* altered to 0xFE.

	In the current code, callers to virNetDevTapCreateInBridgePort each
	make the MAC address modification themselves before calling, which
	leads to code duplication, and also prevents lower level functions
	from knowing the real MAC address being used by the guest. The problem
	here is that openvswitch bridges must be informed about this MAC
	address, or they will be unable to pass traffic to/from the guest.

	This patch centralizes the location of the MAC address "0xFE fixup"
	into virNetDevTapCreateInBridgePort(), meaning 1) callers of this
	function no longer need the extra strange bit of code, and 2)
	bitNetDevTapCreateBridgeInPort itself now is called with the guest's
	unaltered MAC address, and can pass it on, unmodified, to
	virNetDevOpenvswitchAddPort.

	There is no other behavioral change created by this patch.

	build: use correct type for pid and similar types
	No thanks to 64-bit windows, with 64-bit pid_t, we have to avoid

	changed without breaking ABI; but then again, libvirt-qemu can
	only be used on systems that support UNIX sockets, which rules

	This actually wires up the new optional parameter to block_stream:

	The error checking is still sparse, since libvirt must not use

	qemu: require json for block jobs
	Block job commands are not part of upstream qemu until 1.1; and
	proper support of job completion and cancellation depends on being
	able to receive QMP events, which implies the JSON monitor.
	Additionally, some early versions of block job commands were
	backported to RHEL qemu, but these versions lacked asynchronous
	job cancellation and partial block pull, so there are several
	patches that will still be needed in this area of libvirt code
	to support both flavors of block job commands.

	Due to earlier patches in libvirt, we are guaranteed that all versions
	of qemu that support block job commands already require libvirt to
	use the JSON monitor.  That means that the text version of block jobs
	will not be used, and having to refactor two copies of the block job
	handlers makes no sense.  So instead, we delete the text handlers.

	* src/qemu/qemu_monitor.c (qemuMonitorBlockJob): Drop text monitor

	libvirt-guests: Check if URI is reachable before launching commands
	This patch adds a check to the libvirt-guests script to check for the
	URI to be alive before attempting any calls. This avoids nasty error
	messages and allows us to fail gracefully and continue on other URIs
	configured in the script.

	libvirt-guests: Don't try to do a managed-save of transient guests
	The libvirt-guests script tried to do a managed save of transient guest
	that failed. This patch notifies which guests are transient (and not
	being saved) and saves only the persistent ones.

	libvirt-guests: Add documentation and clean up to use virsh's improved list
	This patch adds documentation to functions defined in the libvirt-guests
	init script and changes use of virsh's new commands to make the script

	qemu: unescape HMP commands before converting them to json
	QMP commands don't need to be escaped since converting them to json
	also escapes special characters. When a QMP command fails, however,
	libvirt falls back to HMP commands. These fallback functions
	(qemuMonitorText*) do their own escaping, and pass the result directly
	to qemuMonitorHMPCommandWithFd. If the monitor is in json mode, these
	pre-escaped commands will be escaped again when converted to json,
	which can result in the wrong arguments being sent.

	For example, a filename test\file would be sent in json as
	test\\file.

	This prevented attaching an image file with a " or \ in its name in
	qemu 1.0.50, and also broke rbd attachment (which uses backslashes to
	escape some internal arguments.)

	qemu: Add ability to abort existing console while creating new one
	This patch fixes console corruption, that happens if two concurrent
	sessions are opened for a single console on a domain. Result of this
	corruption was that each of the console streams recieved just a part
	of the data written to the pipe so every console rendered unusable.

	New helper function for safe console handling is used to establish the
	console stream connection. This function ensures that no other libvirt
	client is using the console (with the ability to disconnect consoles of
	libvirt clients) and that no UUCP style lockfile is placed on the PTY
	device.

	* src/qemu/qemu_domain.h
	        - add data structure to domain's private data dealing with
	          console connections
	* src/qemu/qemu_domain.c:
	        - allocate/free domain's console data structure
	* src/qemu/qemu_driver.c
	        - use the new helper function for console handling

2012-02-27  Peter Krempa  <pkrempa@redhat.com>

	util: Add helpers for safe domain console operations
	This patch adds a set of functions used in creating console streams for
	domains using PTYs and ensures mutually exclusive access to the PTYs.

	If mutually exclusive access is not used, two clients may open the same
	console, which results in corruption on both clients as both of them
	race to read data from the PTY.

	Two approaches are used to ensure this:
	1) Internal data structure holding open PTYs.
	        This is used internally and enables the user to forcibly
	        terminate another console connection eg. when somebody leaves
	        the console open on another host.

	2) UUCP style lock files:
	        This uses UUCP lock files according to the  FHS
	        ( http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES )
	        to check if other programs (like minicom) are not using the pty
	        device of the console.

	        This feature is disabled by default and may be enabled using
	        configure parameter
	        --with-console-lock-files=/path/to/lock/file/directory
	        or --with-console-lock-files=auto (which tries to infer the
	        location from OS used (currently only linux).

	        On usual linux systems, normal users may not write to the
	        /var/lock directory containing the locks. This poses problems
	        while in session mode. If the current user has no access to the
	        lockfile directory, check for presence of the file is still
	        done, but no lock file is created. This does NOT result in an
	        error.

	fdstream: Add internal callback on stream close
	This patch adds another callback to a FDstream object. The original
	callback is used by the daemon stream driver to handle events.

	This callback is called if and only if the stream is about to be closed.
	This might be used to handle cleanup steps after a fdstream exits. This
	will be used later on in ensuring mutually exclusive access to consoles.

	* src/fdstream.c:
	        - emit the callback, when stream is being closed
	        - add data structures needed to handle the callback
	        - add function to register callback
	* src/fdstream.h:
	        - define function prototypes for the callback

2012-02-27  Peter Krempa  <pkrempa@redhat.com>

	fdstream: Emit stream abort callback even if poll() doesnt.
	This patch causes the fdstream driver to call the stream event callback
	if virStreamAbort() is called on a stream using this driver.

	A remote handler for a stream can only detect changes via stream events,
	so this event callback is necessary in order to enable a daemon to abort
	a stream in such a way that the client will see the change.

	* src/fdstream.c:
	        - modify close function to call stream event callback

2012-02-27  Peter Krempa  <pkrempa@redhat.com>

	virsh: add support for VIR_DOMAIN_CONSOLE_* flags
	This patch adds support for the newly introduced
	VIR_DOMAIN_CONSOLE_FORCE and VIR_DOMAIN_CONSOLE_SAFE flags. The console
	command now has an optional parameter --force that specifies that the
	user wants to forcibly interrupt an ongoing console session and create
	a new one. Flag --safe requests that the console should be opened only
	if the hypervisor driver supports safe console handling.

	The behaviour to this point was that the daemon opened two streams to
	the console, that competed for data from the pipe, and the result was
	that both of the consoles ended up scrambled.

	This patch doesn't modify operation of other commands dealing with
	console connections (start, create) as those open connections to newly
	started domains making it virtually impossible for another client to race
	for the console and steal it.

	* tools/console.c:
	        - add support for flag passthrough
	* tools/console.h:
	        - modify function prototypes to match impl.
	* tools/virsh.c:
	        - add flag --force for the console command

2012-02-27  Peter Krempa  <pkrempa@redhat.com>

	Add flags for virDomainOpenConsole
	This patch adds a set of flags to be used with the virDomainOpenConsole
	API call to specify if the user wishes to interrupt an existing console
	session or just to try open a new one.

	VIR_DOMAIN_CONSOLE_SAFE - specifies that the console connection should
	                          be opened only if the hypervisor supports
	                          mutually exclusive access to console devices

	VIR_DOMAIN_CONSOLE_FORCE - specifies that the caller wishes to interrupt
	                           existing session and force a creation of a
	                           new one.

	Fixed URI parsing
	Function xmlParseURI does not remove square brackets around IPv6
	address when parsing. One of the solutions is making wrappers around
	functions working with xmlURI*. This assures that uri->server will be
	always properly assigned and it doesn't have to be changed when used
	on some new place in the code.
	For this purpose, functions virParseURI and virSaveURI were
	added. These function are wrappers around xmlParseURI and xmlSaveUri
	respectively.
	Also there is one new syntax check function to prohibit these functions
	anywhere else.

	Error out when using SPICE TLS with spice_tls=0
	It's possible to disable SPICE TLS in qemu.conf. When this happens,
	libvirt ignores any SPICE TLS port or x509 directory that may have
	been set when it builds the qemu command line to use. However, it's
	not ignoring the secure channels that may have been set and adds
	tls-channel arguments to qemu command line.
	Current qemu versions don't report an error when this happens, and try to use
	TLS for the specified channels.

	Before this patch

	<domain type='kvm'>

	generates

	-spice port=5900,addr=0,disable-ticketing,tls-channel=main,tls-channel=inputs

	and starts QEMU.

	After this patch, an error is reported if a TLS port is set in the XML

	they would expect.

	network: support Open vSwitch
	This patch allows libvirt to add interfaces to already
	existing Open vSwitch bridges. The following syntax in
	domain XML file can be used:

	    <interface type='bridge'>
	      <mac address='52:54:00:d0:3f:f2'/>
	      <source bridge='ovsbr'/>
	      <virtualport type='openvswitch'>
	        <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
	      </virtualport>
	      <address type='pci' domain='0x0000' bus='0x00'
	                          slot='0x03' function='0x0'/>
	    </interface>

	or if libvirt should auto-generate the interfaceid use
	following syntax:

	    <interface type='bridge'>
	      <mac address='52:54:00:d0:3f:f2'/>
	      <source bridge='ovsbr'/>
	      <virtualport type='openvswitch'>
	      </virtualport>
	      <address type='pci' domain='0x0000' bus='0x00'
	                          slot='0x03' function='0x0'/>
	    </interface>

	It is also possible to pass an optional profileid. To do that
	use following syntax:

	   <interface type='bridge'>
	     <source bridge='ovsbr'/>
	     <mac address='00:55:1a:65:a2:8d'/>
	     <virtualport type='openvswitch'>
	       <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'
	                   profileid='test-profile'/>
	     </virtualport>
	   </interface>

	To create Open vSwitch bridge install Open vSwitch and
	run the following command:

	    ovs-vsctl add-br ovsbr

	qemu: increase the timeout before sending SIGKILL to qemu process
	The current default method of terminating the qemu process is to send
	a SIGTERM, wait for up to 1.6 seconds for it to cleanly shutdown, then
	send a SIGKILL and wait for up to 1.4 seconds more for the process to
	terminate. This is problematic because occasionally 1.6 seconds is not
	long enough for the qemu process to flush its disk buffers, so the
	guest's disk ends up in an inconsistent state.

	Since this only occasionally happens when the timeout prior to SIGKILL
	is 1.6 seconds, this patch increases that timeout to 10 seconds. At
	the very least, this should reduce the occurrence from "occasionally"
	to "extremely rarely". (Once SIGKILL is sent, it waits another 5
	seconds for the process to die before returning).

	Note that in the cases where it takes less than this for qemu to
	shutdown cleanly, libvirt will *not* wait for any longer than it would
	without this patch - qemuProcessKill polls the process and returns as
	soon as it is gone.

2012-02-16  Laine Stump  <laine@laine.org>

	qemu: drop driver lock while trying to terminate qemu process
	This patch is based on an earlier patch by Eric Blake which was never
	committed:

	https://www.redhat.com/archives/libvir-list/2011-November/msg00243.html

	Aside from rebasing, this patch only drops the driver lock once (prior
	to the first time the function sleeps), then leaves it dropped until
	it returns (Eric's patch would drop and re-acquire the lock around
	each call to sleep).

	At the time Eric sent his patch, the response (from Dan Berrange) was
	that, while it wasn't a good thing to be holding the driver lock while
	sleeping, we really need to rethink locking wrt the driver object,
	switching to a finer-grained approach that locks individual items
	within the driver object separately to allow for greater concurrency.

	This is a good plan, and at the time it made sense to not apply the
	patch because there was no known bug related to the driver lock being
	held in this function.

	However, we now know that the length of the wait in qemuProcessKill is
	sometimes too short to allow the qemu process to fully flush its disk
	cache before SIGKILL is sent, so we need to lengthen the timeout (in
	order to improve the situation with management applications until they
	can be updated to use the new VIR_DOMAIN_DESTROY_GRACEFUL flag added
	in commit 72f8a7f19753506ed957b78ad800c0f3892c9304). But, if we
	lengthen the timeout, we also lengthen the amount of time that all
	other threads in libvirtd are essentially blocked from doing anything
	(since just about everything needs to acquire the driver lock, if only
	for long enough to get a pointer to a domain).

	The solution is to modify qemuProcessKill to drop the driver lock
	while sleeping, as proposed in Eric's patch. Then we can increase the
	timeout with a clear conscience, and thus at least lower the chances
	that someone running with existing management software will suffer the
	consequence's of qemu's disk cache not being flushed.

	In the meantime, we still should work on Dan's proposal to make
	locking within the driver object more fine grained.

	(NB: although I couldn't find any instance where qemuProcessKill() was
	called with no jobs active for the domain (or some other guarantee
	that the current thread had at least one refcount on the domain
	object), this patch still follows Eric's method of temporarily adding
	a ref prior to unlocking the domain object, because I couldn't
	convince myself 100% that this was the case.)

	Install API XML desc to a standard location
	Language bindings may well want to use the libvirt-api.xml and
	libvirt-qemu-api.xml files to either auto-generate themselves,
	or sanity check the manually written bindings for completeness.
	Currently these XML files are not installed as standard, merely
	ending up as a %doc file in the RPM.

	This changes them to be installed into $prefix/share/libvirt/apis/
	The *-refs.xml files are not installed, since those are only
	useful during generation of the online API doc files.

	The pkg-config file is enhanced so that you can query the install
	location of the API files. eg

	  # pkg-config --variable=libvirt_qemu_api libvirt

	qemu: Always use iohelper for domain save
	This is probably not strictly needed as save operation is not live but
	we may have other reasons to avoid blocking qemu's main loop.

	security: Driver 'none' cannot create confined guests
	In case the caller specifies that confined guests are required but the
	security driver turns out to be 'none', we should return an error since
	this driver clearly cannot meet that requirement.  As a result of this
	error, libvirtd fails to start when the host admin explicitly sets
	confined guests are required but there is no security driver available.

	Since security driver 'none' cannot create confined guests, we override
	default confined setting so that hypervisor drivers do not thing they
	should create confined guests.

	seclabel: Do not output relabel attribute for type 'none'
	Security label type 'none' requires relabel to be set to 'no' so there's
	no reason to output this extra attribute.  Moreover, since relabel is
	internally stored in a negative from (norelabel), the default value for
	relabel would be 'yes' in case there is no <seclabel> element in domain
	configuration.  In case VIR_DOMAIN_SECLABEL_DEFAULT turns into
	VIR_DOMAIN_SECLABEL_NONE, we would incorrectly output relabel='yes' for
	seclabel type 'none'.

	qemu: Always use iohelper for dumping domain core
	Qemu uses non-blocking I/O which doesn't play nice with regular file
	descriptors. We need to pass a pipe to qemu instead, which can easily be
	done using iohelper.

	util: Generalize virFileDirectFd
	virFileDirectFd was used for accessing files opened with O_DIRECT using
	libvirt_iohelper. We will want to use the helper for accessing files
	regardless on O_DIRECT and thus virFileDirectFd was generalized and
	renamed to virFileWrapperFd.

	virsh: Plug memory leak on cmdDesc

	virsh: Do not check the input XML at virsh layer for cmdDetachDevice
	Any device XML doesn't use the same order as libvirt generates, or
	uses decimal for attributes like "slot" of "<address>" will cause

	in strict manner before internal parsing.

	This is regression introduced by ea7182c.

	On systems with dmidecode version 2.10 or older,
	 dmidecode displays processor information, followed by BIOS, system and
	 memory-DIMM details.
	 Calls to virSysinfoParseBIOS(), virSysinfoParseSystem() would update
	 the buffer pointer 'base', so the processor information would be lost
	 before virSysinfoParseProcessor() was called. Sysinfo would therefore
	 not be able to display processor details -- It only described <bios>,
	 <system> and <memory_device> details.
	 This patch attempts to insulate sysinfo from ordering of dmidecode
	 output.

	Before the fix:
	---------------
	virsh # sysinfo
	<sysinfo type='smbios'>
	  <bios>
	    ....
	  </bios>
	  <system>
	    ....
	  </system>
	  <memory_device>
	    ....
	  </memory_device>

	After the fix:
	-------------
	virsh # sysinfo

	storage: Don't unsparsify images when cloning
	Input to the volume cloning code is a source volume and an XML
	descriptor for the new volume. It is possible for the new volume
	to have a greater size than source volume, at which point libvirt
	will just stick 0s on the end of the new image (for raw format
	anyways).

	Unfortunately a logic error messed up our tracking of the of the
	excess amount that needed to be written: end result is that sparse
	clones were made very much non-sparse, and cloning regular disk
	images could end up excessively sized (though data unaltered).

	Drop the 'remain' variable entriely here since it's redundant, and
	track actual allocation directly against the desired 'total'.

	build: don't require avahi during install
	See: https://bugzilla.redhat.com/show_bug.cgi?id=785269

	The specfile requires avahi during install if libvirt was built with
	avahi support, but there are many situations where it is undesirable
	to install avahi due to security concerns. This patch requires only
	the avahi-libs package, which is needed by libvirt to call the
	function that tries to attach to the avahi daemon, but will instead
	silently fail because the avahi-daemon is in the main avahi package,
	and that package isn't installed.

	Allow polkit auth for VNC and SSH users
	If you are sitting in front of a physical machine and logged in as
	a regular user, you can connect to the system libvirtd instance
	by providing a root password to policykit. This is how most
	virt-manager users talk to libvirt.

	However, if you are launching virt-manager over ssh -X, or over
	VNC started from say /etc/sysconfig/vncservers, our policykit policy
	rejects the user outright, providing no option to provide the root
	password. This is confusing to users and doesn't seem to serve much
	point.

	Change the policy to allow inactive (VNC) and non-local (SSH, VNC)
	to provide root credentials for accessing system libvirtd. We use
	auth_admin rather than auth_admin_keep so that credentials aren't
	cached at all, and every subsequent reconnection to libvirt requires
	auth.

	xen-xm: fix data loss in domain edit
	On CentOS5:
	If "virsh edit $DOM" is used and an error happens (for example changing
	any live cycle action to a non-existing value), libvirt forgets that
	$DOM exists, since it is already removed from the internal hash tables,
	which are used for domain lookup.
	In once case (unreproducible) even the persistent configuration
	/etc/xen/$DOM was deleted.

	Instead of using the compound function xenXMConfigSaveFile() explicitly
	use xenFomatXM() and virConfWriteFile() to distinguish between a failure
	in converting the libvirt definition to the xen-xm format and a problem
	when writing the file.

	qemu: eliminate "Ignoring open failure" when using root-squash NFS
	This eliminates the warning message reported in:

	 https://bugzilla.redhat.com/show_bug.cgi?id=624447

	It was caused by a failure to open an image file that is not
	accessible by root (the uid libvirtd is running as) because it's on a
	root-squash NFS share, owned by a different user, with permissions of
	660 (or maybe 600).

	The solution is to use virFileOpenAs() rather than open(). The
	codepath that generates the error is during qemuSetupDiskCGroup(), but
	the actual open() is in a lower-level generic function called from
	many places (virDomainDiskDefForeachPath), so some other pieces of the
	code were touched just to add dummy (or possibly useful) uid and gid
	arguments.

	Eliminating this warning message has the nice side effect that the
	requested operation may even succeed (which in this case isn't
	necessary, but shouldn't hurt anything either).

2012-02-04  Laine Stump  <laine@laine.org>

	util: refactor virFileOpenAs
	virFileOpenAs previously would only try opening a file as the current
	user, or as a different user, but wouldn't try both methods in a
	single call. This made it cumbersome to use as a replacement for
	open(2). Additionally, it had a lot of historical baggage that led to
	it being difficult to understand.

	This patch refactors virFileOpenAs in the following ways:

	* reorganize the code so that everything dealing with both the parent
	  and child sides of the "fork+setuid+setgid+open" method are in a
	  separate function. This makes the public function easier to understand.

	* Allow a single call to virFileOpenAs() to first attempt the open as
	  the current user, and if that fails to automatically re-try after
	  doing fork+setuid (if deemed appropriate, i.e. errno indicates it
	  would now be successful, and the file is on a networkFS). This makes
	  it possible (in many, but possibly not all, cases) to drop-in
	  virFileOpenAs() as a replacement for open(2).

	  (NB: currently qemuOpenFile() calls virFileOpenAs() twice, once
	  without forking, then again with forking. That unfortunately can't
	  be changed without at least some discussion of the ramifications,
	  because the requested file permissions are different in each case,
	  which is something that a single call to virFileOpenAs() can't deal
	  with.)

	* Add a flag so that any fchown() of the file to a different uid:gid
	  is explicitly requested when the function is called, rather than it
	  being implied by the presence of the O_CREAT flag. This just makes
	  for less subtle surprises to consumers. (Commit
	  b1643dc15c5de886fefe56ad18608d65f1325a2c added the check for O_CREAT
	  before forcing ownership. This patch just makes that restriction
	  more explicit.)

	* If either the uid or gid is specified as "-1", virFileOpenAs will
	  interpret this to mean "the current [gu]id".

	All current consumers of virFileOpenAs should retain their present
	behavior (after a few minor changes to their setup code and
	arguments).

	virsh: add --graceful switch to destroy command
	This allows virsh to use the new VIR_DOMAIN_DESTROY_GRACEUL flag for
	virDomainDestroyFlags.

2012-02-04  Laine Stump  <laine@laine.org>

	qemu: new GRACEFUL flag for virDomainDestroy w/ QEMU support
	When libvirt's virDomainDestroy API is shutting down the qemu process,
	it first sends SIGTERM, then waits for 1.6 seconds and, if it sees the
	process still there, sends a SIGKILL.

	There have been reports that this behavior can lead to data loss
	because the guest running in qemu doesn't have time to flush its disk
	cache buffers before it's unceremoniously whacked.

	This patch maintains that default behavior, but provides a new flag
	VIR_DOMAIN_DESTROY_GRACEFUL to alter the behavior. If this flag is set
	in the call to virDomainDestroyFlags, SIGKILL will never be sent to
	the qemu process; instead, if the timeout is reached and the qemu
	process still exists, virDomainDestroy will return an error.

	Once this patch is in, the recommended method for applications to call
	virDomainDestroyFlags will be with VIR_DOMAIN_DESTROY_GRACEFUL
	included. If that fails, then the application can decide if and when
	to call virDomainDestroyFlags again without
	VIR_DOMAIN_DESTROY_GRACEFUL (to force the issue with SIGKILL).

	(Note that this does not address the issue of existing applications
	that have not yet been modified to use VIR_DOMAIN_DESTROY_GRACEFUL.
	That is a separate patch.)

	Add support for sVirt in the LXC driver
	For the sake of backwards compat, LXC guests are *not*
	confined by default. This is because it is not practical
	to dynamically relabel containers using large filesystem
	trees. Applications can create confined containers though,
	by giving suitable XML configs

2012-02-03  Daniel P. Berrange  <berrange@redhat.com>

	Add two new security label types
	Curently security labels can be of type 'dynamic' or 'static'.
	If no security label is given, then 'dynamic' is assumed. The
	current code takes advantage of this default, and avoids even
	saving <seclabel> elements with type='dynamic' to disk. This
	means if you temporarily change security driver, the guests
	can all still start.

	With the introduction of sVirt to LXC though, there needs to be
	a new default of 'none' to allow unconfined LXC containers.

	This patch introduces two new security label types

	 - default:  the host configuration decides whether to run the
	             guest with type 'none' or 'dynamic' at guest start
	 - none:     the guest will run unconfined by security policy

	The 'none' label type will obviously be undesirable for some
	deployments, so a new qemu.conf option allows a host admin to
	mandate confined guests. It is also possible to turn off default
	confinement

	  security_default_confined = 1|0  (default == 1)
	  security_require_confined = 1|0  (default == 0)

	* src/conf/domain_conf.c, src/conf/domain_conf.h: Add new

	    seclabel: allow a seclabel override on a disk src

	These two commits changed the sec label parsing code so that
	the same code dealt with both the VM level sec label, and the

	VM level sec label, the logic required to use the same parsing
	code for the per device label becomes unintelligible.

	tests: dynamically replace dnsmasq path
	The path to the dnsmasq binary can be configured while in the test data
	the path is hard-coded to /usr/bin/. This break the test suite if a the
	binary is located in a different location, like /usr/local/sbin/.

	Replace the hard coded path in the test data by a token, which is
	dynamically replaced in networkxml2argvtest with the configured path
	after the test data has been loaded.

	(Another option would have been to modify configure.ac to generate the
	 test data during configure, but I do not know of an easy way do trick
	 configure into mass-generate those test files without listing every
	 single one, which I consider less flexible.)

	block rebase: add new API virDomainBlockRebase
	Qemu is adding the ability to do a partial rebase.  That is, given:

	base <- intermediate <- current

	virDomainBlockPull will produce:

	current

	but qemu now has the ability to leave base in the chain, to produce:

	base <- current

	Note that current qemu can only do a forward merge, and only with
	the current image as the destination, which is fully described by
	this API without flags.  But in the future, it may be possible to
	enhance this API for additional scenarios by using flags:

	Merging the current image back into a previous image (that is,
	undoing a live snapshot), could be done by passing base as the
	destination and flags with a bit requesting a backward merge.

	Merging any other part of the image chain, whether forwards (the
	backing image contents are pulled into the newer file) or backwards
	(the deltas recorded in the newer file are merged back into the
	backing file), could also be done by passing a new flag that says
	that base should be treated as an XML snippet rather than an
	absolute path name, where the XML could then supply the additional
	instructions of which part of the image chain is being merged into
	any other part.

	* include/libvirt/libvirt.h.in (virDomainBlockRebase): New
	declaration.
	* src/libvirt.c (virDomainBlockRebase): Implement it.
	* src/libvirt_public.syms (LIBVIRT_0.9.10): Export it.

2012-02-01  Eric Blake  <eblake@redhat.com>

	Our existing virDomainBlockResize takes an unsigned long long
	argument; if that command is later taught a DELTA and SHRINK flag,
	we cannot change its type without breaking API (but at least such
	a change would be ABI compatible).  Meanwhile, the only time a
	negative size makes sense is if both DELTA and SHRINK are used
	together, but if we keep the argument unsigned, applications can
	pass the positive delta amount by which they would like to shrink
	the system, and have the flags imply the negative value.  So,
	since this API has not yet been released, and in the interest of
	consistency with existing API, we swap virStorageVolResize to
	always pass an unsigned value.

	qemu: add "romfile" support to specify device boot ROM
	This patch addresses: https://bugzilla.redhat.com/show_bug.cgi?id=781562

	Along with the "rombar" option that controls whether or not a boot rom
	is made visible to the guest, qemu also has a "romfile" option that
	allows specifying a binary file to present as the ROM BIOS of any
	emulated or passthrough PCI device. This patch adds support for
	specifying romfile to both passthrough PCI devices, and emulated
	network devices that attach to the guest's PCI bus (just about
	everything other than ne2k_isa).

	One example of the usefulness of this option is described in the
	bugzilla report: 82576 sriov network adapters don't provide a ROM BIOS
	for the cards virtual functions (VF), but an image of such a ROM is
	available, and with this ROM visible to the guest, it can PXE boot.

	In libvirt's xml, the new option is configured like this:

	   <hostdev>
	     ...
	     <rom file='/etc/fake/boot.bin'/>
	     ...
	   </hostdev

	(similarly for <interface>).

2012-01-31  Laine Stump  <laine@laine.org>

	qemu: (and conf) support rombar for network devices
	When support for the rombar option was added, it was only added for
	PCI passthrough devices, configured with <hostdev>. The same option is
	available for any network device that is attached to the guest's PCI
	bus. This patch allows setting rombar for any PCI network device type.

	After adding cases to test this to qemuxml2argv-hostdev-pci-rombar.*,
	I decided to rename those files (to qemuxml2argv-pci-rom.*) to more
	accurately reflect the additional tests, and also noticed that up to
	now we've only been performing a domainschematest for that case, so I
	added the "pci-rom" test to both qemuxml2argv and qemuxml2xml (and in
	the process found some bugs whose fixes I squashed into previous
	commits of this series).

2012-01-31  Laine Stump  <laine@laine.org>

	conf: relocate rombar and boot order parse/format
	Since these two items are now in the virDomainDeviceInfo struct, it
	makes sense to parse/format them in the functions written to
	parse/format that structure. Not all types of devices allow them, so
	two internal flags are added to indicate when it is appropriate to do
	so.

	I was lucky - only one test case needed to be re-ordered!

2012-01-31  Laine Stump  <laine@laine.org>

	conf: put all guest-related HostdevDef data in one object
	To help consolidate the commonality between virDomainHostdevDef and
	virDomainNetDef into as few members as possible (and because I
	think it makes sense), this patch moves the rombar and bootIndex
	members into the "info" member that is common to both (and to all the
	other structs that use them).

	It's a bit problematic that this gives rombar and bootIndex to many
	device types that don't use them, but this is already the case for the
	master and mastertype members of virDomainDeviceInfo, and is properly
	commented as such in the definition.

	Note that this opens the door to supporting rombar for other devices
	that are attached to the guest PCI bus - virtio-blk-pci,
	virtio-net-pci, various other network adapters - which which have that
	capability in qemu, but previously had no support in libvirt.

	qemu: parse and create -cpu ...,-kvmclock
	QEMU supports a bunch of CPUID features that are tied to the kvm CPUID
	nodes rather than the processor's.  They are "kvmclock",
	"kvm_nopiodelay", "kvm_mmu", "kvm_asyncpf".  These are not known to
	libvirt and their CPUID leaf might move if (for example) the Hyper-V
	extensions are enabled. Hence their handling would anyway require some
	special-casing.

	However, among these the most useful is kvmclock; an additional
	"property" of this feature is that a <timer> element is a better model
	than a CPUID feature.  Although, creating part of the -cpu command-line
	from something other than the <cpu> XML element introduces some
	ugliness.

	architectures, representing a least common denominator of all
	hosts that can run KVM.  Add them to the machine map.

	Also, some features that TCG supports were added to qemu64.
	Add them to the cpu_map.xml whenever KVM is guaranteed to support
	those.  We still have to leave some out, because they would not
	be available to guests running on older hosts.

	qemu: parse -enable-kvm

2012-01-27  Eric Blake  <eblake@redhat.com>

	qemu: require qmp on new enough qemu
	The qemu developers have made it clear that modern qemu will no
	longer guarantee human monitor command stability; furthermore,
	some features, such as async events, are only supported via qmp.
	If we are compiled without support for handling JSON, we cannot
	expect to sanely interact with modern qemu.

	However, things must continue to build on RHEL 5, where qemu
	is stuck at 0.10, and where yajl is not available.

	Another benefit of this patch: future additions of new monitor
	commands need only focus on qemu_monitor_json.c, instead of
	also wasting time with qemu_monitor_text.c.

	* src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Report
	error if yajl is missing but qemu requires qmp.
	(qemuCapsParseHelpStr): Propagate error.
	(qemuCapsExtractVersionInfo): Update caller.
	* tests/qemuhelptest.c (testHelpStrParsing): Likewise.

	qemu: support qmp on RHEL/CentOS qemu
	I'm getting tired of remembering to backport RHEL-specific
	patches when building upstream libvirt on RHEL 6.x or CentOS.
	All the affected versions of RHEL qemu-kvm have backported
	enough patches to a) make JSON useful, and b) modify the
	-help text to mention libvirt as the preferred interface;
	which means this string in the help output is a reliable
	indicator that we can outsmart a strict version check,
	even when upstream qemu 0.12 lacked the needed features.

	* src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags):
	Recognize particular help string present when enough features were
	backported to be worth using JSON.
	* tests/qemuhelptest.c (mymain): Update tests accordingly.

	nwfilter: Rebuild filters only if new filter is different than current
	Compare two filters' XML for equality and only rebuild/instantiate the new

	qemu: Refactor qemuMonitorGetBlockInfo
	QEMU always sends details about all available block devices as an answer
	for "info block"/"query-block" command. On the other hand, our
	qemuMonitorGetBlockInfo was made for a single block devices queries
	only. Thus, when asking for multiple devices, we asked qemu multiple
	times to always get the same answer from which different parts were
	filtered. This patch makes qemuMonitorGetBlockInfo return a hash table

	Replace hashing algorithm with murmurhash
	Recent discussions have illustrated the potential for DOS attacks
	with the hash table implementations used by most languages and
	libraries.

	   https://lwn.net/Articles/474912/

	libvirt has an internal hash table impl, and uses hash tables for
	a variety of purposes. The hash key generation code is pretty
	simple and thus not strongly collision resistant.

	This patch replaces the current libvirt hash key generator with
	the (public domain) Murmurhash3 code. In addition every hash
	table now gets a random seed value which is used to perturb the
	hashing code. This should make it impossible to mount any
	practical attack against libvirt hashing code.

	* bootstrap.conf: Import bitrotate module
	* src/Makefile.am: Add virhashcode.[ch]
	* src/util/util.c: Make virRandom() return a fixed 32 bit
	  integer value.
	* src/util/hash.c, src/util/hash.h, src/util/cgroup.c: Replace
	  hash code generation with a call to virHashCodeGen()
	* src/util/virhashcode.h, src/util/virhashcode.c: Add a new
	  virHashCodeGen() API using the Murmurhash3 algorithm.

2012-01-26  Daniel P. Berrange  <berrange@redhat.com>

	Rename  hash.h and hash.c to virhash.h and virhash.c
	In preparation for the patch to include Murmurhash3, which
	introduces a virhashcode.h and virhashcode.c files, rename
	the existing hash.h and hash.c to virhash.h and virhash.c
	respectively.

	Convert various virHash functions to use size_t / uint32
	In preparation for conversion over to use the Murmurhash3
	algorithm, convert various virHash APIs to use size_t or
	uint32 for their return values/parameters, instead of the
	variable size 'unsigned long' or 'int' types

	storage: Fix any VolLookupByPath if we have an empty logical pool
	On F16 at least, empty volume groups don't have a directory under /dev.
	The directory only appears once a logical volume is created.

	This tickles some behavior in BackendStablePath which ends with
	libvirt sleeping for 5 seconds while waiting for the directory to appear.
	This causes all sorts of problems for the virStorageVolLookupByPath API
	which virtinst uses, even if trying to resolve a path that is independent
	of the logical pool.

	In reality we don't even need to do that checking since logical pools
	always have a stable target path. Short circuit the polling in that
	case.

	virCommandProcessIO(): make poll() usage more robust
	POLLIN and POLLHUP are not mutually exclusive. Currently the following
	seems possible: the child writes 3K to its stdout or stderr pipe, and
	immediately closes it. We get POLLIN|POLLHUP (I'm not sure that's possible
	on Linux, but SUSv4 seems to allow it). We read 1K and throw away the
	rest.

	When poll() returns and we're about to check the /revents/ member in a
	given array element, let's map all the revents bits to two (independent)
	ideas: "let's attempt to read()", and "let's attempt to write()". This
	should cover all errors, EOFs, and normal conditions; the read()/write()
	call should report any pending error.

	Under this approach, both POLLHUP and POLLERR are mapped to "needs read()"
	if we're otherwise prepared for POLLIN. POLLERR also maps to "needs
	write()" if we're otherwise prepared for POLLOUT. The rest of the mappings
	(POLLPRI etc.) would be easy, but probably useless for pipes.

	Additionally, SUSv4 doesn't appear to forbid POLLIN|POLLERR (or
	POLLOUT|POLLERR) set simultaneously. One could argue that the read() or
	write() call would return without blocking in these cases (with an error),
	so POLLIN / POLLOUT would be justified beside POLLERR.

	The code now penalizes POLLIN|POLLERR differently from plain POLLERR. The
	former (ie. read() returning -1) is terminal and we jump to cleanup, while
	plain POLLERR masks only the affected file descriptor for the future.
	Let's unify those.

	Fix startup of LXC containers with filesystems containing symlinks
	Given an LXC guest with a root filesystem path of

	  /export/lxc/roots/helloworld/root

	During startup, we will pivot the root filesystem to end up
	at

	  /.oldroot/export/lxc/roots/helloworld/root

	We then try to open

	  /.oldroot/export/lxc/roots/helloworld/root/dev/pts

	Now consider if '/export/lxc' is an absolute symlink pointing
	to '/media/lxc'. The kernel will try to open

	  /media/lxc/roots/helloworld/root/dev/pts

	whereas it should be trying to open

	  /.oldroot//media/lxc/roots/helloworld/root/dev/pts

	qemu: Prohibit reattaching node device if it is in use
	It doesn't make sense to reattach a device to host while it's
	still in use, e.g, by a domain.

2012-01-18  Osier Yang  <jyang@redhat.com>

	qemu: Introduce inactive PCI device list
	pciTrySecondaryBusReset checks if there is active device on the
	same bus, however, qemu driver doesn't maintain an effective
	list for the inactive devices, and it passes meaningless argument
	for parameter "inactiveDevs". e.g. (qemuPrepareHostdevPCIDevices)

	if (!(pcidevs = qemuGetPciHostDeviceList(hostdevs, nhostdevs)))
	    return -1;

	..skipped...

	if (pciResetDevice(dev, driver->activePciHostdevs, pcidevs) < 0)
	    goto reattachdevs;

	NB, the "pcidevs" used above are extracted from domain def, and
	thus one won't be able to attach a device of which bus has other
	device even detached from host (nodedev-detach). To see more
	details of the problem:

	RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=773667

	This patch is to resolve the problem by introducing an inactive
	PCI device list (just like qemu_driver->activePciHostdevs), and
	the whole logic is:

	  * Add the device to inactive list during nodedev-dettach
	  * Remove the device from inactive list during nodedev-reattach
	  * Remove the device from inactive list during attach-device
	    (for non-managed device)
	  * Add the device to inactive list after detach-device, only
	    if the device is not managed

	With the above, we have a sufficient inactive PCI device list, and thus
	we can use it for pciResetDevice. e.g.(qemuPrepareHostdevPCIDevices)

	if (pciResetDevice(dev, driver->activePciHostdevs,
	                   driver->inactivePciHostdevs) < 0)
	    goto reattachdevs;

	Add new attribute wrpolicy to <driver> element
	This introduces new attribute wrpolicy with only supported
	value as immediate. This will be an optional
	attribute with no defaults. This helps specify whether
	to skip the host page cache.

	When wrpolicy is specified, meaning when wrpolicy=immediate
	a writeback is explicitly initiated for the dirty pages in
	the host page cache as part of the guest file write operation.

	Usage:
	<filesystem type='mount' accessmode='passthrough'>
	  <driver type='path' wrpolicy='immediate'/>
	  <source dir='/export/to/guest'/>
	  <target dir='mount_tag'/>
	</filesystem>

	Currently this only works with type='mount' for the QEMU/KVM driver.

	qemu: Don't break domain with 0:0:2.0 assigned to anything but VGA
	In the past we didn't reserve 0:0:2.0 PCI address if there was no video
	device assigned to a domain, which made it impossible to add a video
	device later on. So we fixed it (commit v0.9.0-37-g7b2cac1) by always
	reserving that address. However, that breaks existing domains without
	video devices that already have another device assigned to the
	problematic address.

	This patch reserves address 0:0:2.0 only in case it was not explicitly
	assigned to another device, which means libvirt will try to keep this
	address free and will not automatically assign it new devices. But
	existing domains for which older libvirt already assigned the address to
	a non-video device will keep working as they used to work before 0.9.1.
	Moreover, users who want to create a domain without a video device and
	use its address for another device may do so by explicitly configuring
	the PCI address in domain XML.

	qemu: Add support for host CPU modes
	This adds support for host-model and host-passthrough CPU modes to qemu
	driver. The host-passthrough mode is mapped to -cpu host.

2012-01-17  Jiri Denemark  <jdenemar@redhat.com>

	Taint domains configured with cpu mode=host-passthrough
	There are several reasons for doing this:

	- the CPU specification is out of libvirt's control so we cannot
	  guarantee stable guest ABI
	- not every feature of a CPU may actually work as expected when
	  advertised directly to a guest
	- migration between two machines with exactly the same CPU may work but
	  no guarantees can be made
	- this mode is not supported and its use is at one's own risk

2012-01-17  Jiri Denemark  <jdenemar@redhat.com>

	cpu: Update guest CPU in host-* mode
	VIR_DOMAIN_XML_UPDATE_CPU flag for virDomainGetXMLDesc may be used to
	get updated custom mode guest CPU definition in case it depends on host
	CPU. This patch implements the same behavior for host-model and
	host-passthrough CPU modes.

2012-01-17  Jiri Denemark  <jdenemar@redhat.com>

	Add support for cpu mode attribute
	The mode can be either of "custom" (default), "host-model",
	"host-passthrough". The semantics of each mode is described in the
	following examples:

	- guest CPU is a default model with specified topology:
	    <cpu>
	      <topology sockets='1' cores='2' threads='1'/>
	    </cpu>

	- guest CPU matches selected model:
	    <cpu mode='custom' match='exact'>
	      <model>core2duo</model>
	    </cpu>

	- guest CPU should be a copy of host CPU as advertised by capabilities
	  XML (this is a short cut for manually copying host CPU specification
	  from capabilities to domain XML):
	    <cpu mode='host-model'/>

	  In case a hypervisor does not support the exact host model, libvirt
	  automatically falls back to a closest supported CPU model and
	  removes/adds features to match host. This behavior can be disabled by
	    <cpu mode='host-model'>
	      <model fallback='forbid'/>
	    </cpu>

	- the same as previous returned by virDomainGetXMLDesc with
	  VIR_DOMAIN_XML_UPDATE_CPU flag:
	    <cpu mode='host-model' match='exact'>
	      <model fallback='allow'>Penryn</model>       --+
	      <vendor>Intel</vendor>                         |
	      <topology sockets='2' cores='4' threads='1'/>  + copied from
	      <feature policy='require' name='dca'/>         | capabilities XML
	      <feature policy='require' name='xtpr'/>        |
	      ...                                          --+
	    </cpu>

	- guest CPU should be exactly the same as host CPU even in the aspects
	  libvirt doesn't model (such domain cannot be migrated unless both
	  hosts contain exactly the same CPUs):
	    <cpu mode='host-passthrough'/>

	- the same as previous returned by virDomainGetXMLDesc with
	  VIR_DOMAIN_XML_UPDATE_CPU flag:
	    <cpu mode='host-passthrough' match='minimal'>
	      <model>Penryn</model>                        --+ copied from caps
	      <vendor>Intel</vendor>                         | XML but doesn't
	      <topology sockets='2' cores='4' threads='1'/>  | describe all
	      <feature policy='require' name='dca'/>         | aspects of the
	      <feature policy='require' name='xtpr'/>        | actual guest CPU
	      ...                                          --+
	    </cpu>

2012-01-17  Jiri Denemark  <jdenemar@redhat.com>

	cpu: Optionally forbid fallback CPU models
	In case a hypervisor doesn't support the exact CPU model requested by a
	domain XML, we automatically fallback to a closest CPU model the
	hypervisor supports (and make sure we add/remove any additional features
	if needed). This patch adds 'fallback' attribute to model element, which
	can be used to disable this automatic fallback.

	    x86-host+guest,models,qemu64-result.xml

	where the expected XML is stored. Better to provide a nice hint in
	verbose mode for failed tests.

	Clarify semantics of virDomainMigrate{,ToURI}2
	Commit 5d784bd6d7b19314b0908aec6b46bfe377aeba42 was a nice attempt to
	clarify the semantics by requiring domain name from dxml to either match
	original name or dname. However, setting dxml domain name to dname
	doesn't really work since destination host needs to know the original
	domain name to be able to use it in migration cookies. This patch
	requires domain name in dxml to match the original domain name. The
	change should be safe and backward compatible since migration would fail
	just a bit later in the process.

	tests: Add qemuxml2argv tests for PPC64 pseries machine
	Add four tests of the XML -> argv handling for the PPC64 pseries machine.

	The first is just a basic test of a bare bones machine.

	The three others test various aspects of the spapr-vio address handling.

	It seems that currently we can't include network devices, doing so leads
	to a segfault because the network driverState is not initialised. Working
	around that leads us to the problem that the 'default' network doesn't
	exist. So for now just leave network devices out.

2012-01-14  Michael Ellerman  <michael@ellerman.id.au>

	tests: Teach qemuxml2argvtest about spapr-vio addresses
	We can't call qemuCapsExtractVersionInfo() from test code, because it
	expects to be able to call the emulator, and for testing we have fake
	emulators that can't be executed. For that reason qemuxml2argvtest.c
	doesn't call qemuDomainAssignPCIAddresses(), instead it open codes its
	own version.

	That means we can't call qemuDomainAssignAddresses() from the test code,
	instead we need to manually call qemuDomainAssignSpaprVioAddresses().

	Also add logic to cope with qemuDomainAssignSpaprVioAddresses() failing,
	so that we can write a test that checks for a known failure in there.

	events: Return the correct number of registered events
	Commit d09f6ba5feb655925175dc80122ca2a1e14db2b9 introduced a regression in event
	registration.  virDomainEventCallbackListAddID() will only return a positive
	integer if the type of event being registered is VIR_DOMAIN_EVENT_ID_LIFECYCLE.
	For other event types, 0 is always returned on success.  This has the
	unfortunate side effect of not enabling remote event callbacks because
	remoteDomainEventRegisterAny() uses the return value from the local call to
	determine if an event callback needs to be registered on the remote end.

	Make sure virDomainEventCallbackListAddID() returns the callback count for the
	eventID being registered.

2012-01-13  Daniel P. Berrange  <berrange@redhat.com>

	Re-write LXC controller end-of-file I/O handling yet again
	Currently the LXC controller attempts to deal with EOF on a
	tty by spawning a thread to do an edge triggered epoll_wait().
	This avoids the normal event loop spinning on POLLHUP. There
	is a subtle mistake though - even after seeing POLLHUP on a
	master PTY, it is still perfectly possible & valid to write
	data to the PTY. There is a buffer that can be filled with
	data, even when no client is present.

	The second mistake is that the epoll_wait() thread was not
	looking for the EPOLLOUT condition, so when a new client
	connects to the LXC console, it had to explicitly send a
	character before any queued output would appear.

	Finally, there was in fact no need to spawn a new thread to
	deal with epoll_wait(). The epoll file descriptor itself
	can be poll()'d on normally.

	This patch attempts to deal with all these problems.

	 - The blocking epoll_wait() thread is replaced by a poll
	   on the epoll file descriptor which then does a non-blocking
	   epoll_wait() to handle events
	 - Even if POLLHUP is seen, we continue trying to write
	   any pending output until getting EAGAIN from write.
	 - Once write returns EAGAIN, we modify the epoll event
	   mask to also look for EPOLLOUT

	Allow 10 chars for domain IDs & 30 chars for names in virsh list
	Domain IDs are at least 16 bits for most hypervisors, theoretically
	event 32-bits.  3 characters is clearly too small an alignment.
	Increase alignment to 5 characters to allow 16-bit domain IDs to
	display cleanly. Commonly seen with LXC where domain IDs are the
	process IDs by default.  Also increase the 'name' field from 20
	to 30 characters to cope with longer guest names which are quite
	common

	stream: Check for stream EOF
	If client stream does not have any data to sink and neither received
	EOF, a dummy packet is sent to the daemon signalising client is ready to
	sink some data. However, after we added event loop to client a race may
	occur:

	Thread 1 calls virNetClientStreamRecvPacket and since no data are cached
	nor stream has EOF, it decides to send dummy packet to server which will
	sent some data in turn. However, during this decision and actual message
	exchange with server -

	Thread 2 receives last stream data from server. Therefore an EOF is set
	on stream and if there is a call waiting (which is not yet) it is woken
	up. However, Thread 1 haven't sent anything so far, so there is no call
	to be woken up. So this thread sent dummy packet to daemon, which
	ignores that as no stream is associated with such packet and therefore
	no reply will ever come.

	This race causes client to hang indefinitely.

	Do not generate security_model when fs driver is anything but 'path'
	QEMU does not support security_model for anything but 'path' fs driver type.
	Currently in libvirt, when security_model ( accessmode attribute) is not
	specified it auto-generates it irrespective of the fs driver type, which
	can result in a qemu error for drivers other than path. This patch ensures
	that the qemu cmdline is correctly generated by taking into account the
	fs driver type.

	This is because the gnulib headers #define close to different strings,

	affect field members declared with a name of struct foo.close. As long

	Add test cases for new ways to access variables in filters
	This patch adds a couple of XML parser / schema validator test cases

	Address side effects of accessing vars via index
	Address side effect of accessing a variable via an index: Filters
	accessing a variable where an element is accessed that is beyond the

	cannot instantiate that filter. Test for this and report proper error
	to user.

2012-01-11  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Add access to elements of variables via index
	This patch adds access to single elements of variables via index. Example:

	  <rule action='accept' direction='in' priority='500'>
	    <tcp srcipaddr='$ADDR[1]' srcportstart='$B[2]'/>
	  </rule>

2012-01-11  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Introduce possibility to have an iterator per variable
	This patch introduces the capability to use a different iterator per
	variable.

	The currently supported notation of variables in a filtering rule like

	  <rule action='accept' direction='out'>
	     <tcp  srcipaddr='$A' srcportstart='$B'/>
	  </rule>

	processes the two lists 'A' and 'B' in parallel. This means that A and B
	must have the same number of 'N' elements and that 'N' rules will be 
	instantiated (assuming all tuples from A and B are unique).

	In this patch we now introduce the assignment of variables to different
	iterators. Therefore a rule like

	  <rule action='accept' direction='out'>
	     <tcp  srcipaddr='$A[@1]' srcportstart='$B[@2]'/>
	  </rule>

	will now create every combination of elements in A with elements in B since
	A has been assigned to an iterator with Id '1' and B has been assigned to an
	iterator with Id '2', thus processing their value independently.

	The first rule has an equivalent notation of

	  <rule action='accept' direction='out'>
	     <tcp  srcipaddr='$A[@0]' srcportstart='$B[@0]'/>
	  </rule>

2012-01-11  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Optimize the elements the iterator visits.
	In this patch we introduce testing whether the iterator points to a
	unique set of entries that have not been seen before at one of the previous
	iterations. The point is to eliminate duplicates and with that unnecessary
	filtering rules by preventing identical filtering rules from being
	instantiated.
	Example with two lists:

	list1 = [1,2,1]
	list2 = [1,3,1]

	The 1st iteration would take the 1st items of each list -> 1,1
	The 2nd iteration would take the 2nd items of each list -> 2,3
	The 3rd iteration would take the 3rd items of each list -> 1,1 but
	skip them since this same pair has already been encountered in the 1st
	iteration

	Implementation-wise this is solved by taking the n-th element of list1 and
	comparing it against elements 1..n-1. If no equivalent is found, then there
	is no possibility of this being a duplicate. In case an equivalent element
	is found at position i, then the n-th element in the 2nd list is compared
	against the i-th element in the 2nd list and if that is not the same, then
	this is a unique pair, otherwise it is not unique and we may need to do
	the same comparison on the 3rd list.

	Aside from two functions which want obj->pid, every bit of the

	snapshot: allow reuse of existing files in disk snapshot
	When disk snapshots were first implemented, libvirt blindly refused
	to allow an external snapshot destination that already exists, since
	qemu will blindly overwrite the contents of that file during the
	snapshot_blkdev monitor command, and we don't like a default of
	data loss by default.  But VDSM has a scenario where NFS permissions
	are intentionally set so that the destination file can only be
	created by the management machine, and not the machine where the
	guest is running, so that libvirt will necessarily see the destination
	file already existing; adding a flag will allow VDSM to force the file
	reuse without libvirt complaining of possible data loss.

	qemu: check for kvm availability before starting kvm guests
	This *kind of* addresses:

	  https://bugzilla.redhat.com/show_bug.cgi?id=772395

	(it doesn't eliminate the failure to start, but causes libvirt to give
	a better idea about the cause of the failure).

	If a guest uses a kvm emulator (e.g. /usr/bin/qemu-kvm) and the guest
	is started when kvm isn't available (either because virtualization is
	unavailable / has been disabled in the BIOS, or the kvm modules
	haven't been loaded for some reason), a semi-cryptic error message is
	logged:

	  libvirtError: internal error Child process (LC_ALL=C
	  PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -device ? -device
	  pci-assign,? -device virtio-blk-pci,? -device virtio-net-pci,?) status
	  unexpected: exit status 1

	This patch notices at process start that a guest needs kvm, and checks
	for the presence of /dev/kvm (a reasonable indicator that kvm is
	available) before trying to execute the qemu binary. If kvm isn't
	available, a more useful (too verbose??) error is logged.

	PolicyKit: Check auth before asking client to obtain it
	I previously mentioned [1] a PolicyKit issue where libvirt would
	proceed with authentication even though polkit-auth failed:

	testusr xen134:~> virsh list --all
	Attempting to obtain authorization for org.libvirt.unix.manage.
	polkit-grant-helper: given auth type (8 -> yes) is bogus
	Failed to obtain authorization for org.libvirt.unix.manage.

	----------------------------------
	  0 Domain-0             running
	  - sles11sp1-pv         shut off

	AFAICT, libvirt attempts to obtain a privilege it already has,
	causing polkit-auth to fail with above message.  Instead of calling
	obtain and then checking auth, IMO the workflow should be for the
	server to check auth first, and if that fails ask the client to
	obtain it and check again.  This workflow also allows for checking
	only successful exit of polkit-auth in virConnectAuthGainPolkit().

	qemu: add new disk device='lun' for bus='virtio' & type='block'
	In the past, generic SCSI commands issued from a guest to a virtio
	disk were always passed through to the underlying disk by qemu, and
	the kernel would also pass them on.

	As a result of CVE-2011-4127 (see:
	http://seclists.org/oss-sec/2011/q4/536), qemu now honors its
	scsi=on|off device option for virtio-blk-pci (which enables/disables
	passthrough of generic SCSI commands), and the kernel will only allow
	the commands for physical devices (not for partitions or logical
	volumes). The default behavior of qemu is still to allow sending
	generic SCSI commands to physical disks that are presented to a guest
	as virtio-blk-pci devices, but libvirt prefers to disable those
	commands in the standard virtio block devices, enabling it only when
	specifically requested (hopefully indicating that the requester
	understands what they're asking for). For this purpose, a new libvirt
	disk device type (device='lun') has been created.

	device='lun' is identical to the default device='disk', except that:

	1) It is only allowed if bus='virtio', type='block', and the qemu
	   version is "new enough" to support it ("new enough" == qemu 0.11 or
	   better), otherwise the domain will fail to start and a
	   CONFIG_UNSUPPORTED error will be logged).

	2) The option "scsi=on" will be added to the -device arg to allow
	   SG_IO commands (if device !='lun', "scsi=off" will be added to the
	   -device arg so that SG_IO commands are specifically forbidden).

	Guests which continue to use disk device='disk' (the default) will no
	longer be able to use SG_IO commands on the disk; those that have
	their disk device changed to device='lun' will still be able to use SG_IO
	commands.

	*docs/formatdomain.html.in - document the new device attribute value.
	*docs/schemas/domaincommon.rng - allow it in the RNG
	*tests/* - update the args of several existing tests to add scsi=off, and
	 add one new test that will test scsi=on.
	*src/conf/domain_conf.c - update domain XML parser and formatter

	*src/qemu/qemu_(command|driver|hotplug).c - treat
	 VIR_DOMAIN_DISK_DEVICE_LUN *almost* identically to
	 VIR_DOMAIN_DISK_DEVICE_DISK, except as indicated above.

	Note that no support for this new device value was added to any
	hypervisor drivers other than qemu, because it's unclear what it might
	mean (if anything) to those drivers.

	qemu: add capabilities flags related to SG_IO

	    set if -device virtio-blk-pci accepts the scsi="on|off" option
	    When present, this is on by default, but can be set to off to disable
	    SG_IO functions.

	  QEMU_CAPS_VIRTIO_BLK_SG_IO
	    set if SG_IO commands are supported in the virtio-blk-pci driver
	    (present since qemu 0.11 according to a qemu developer, if I
	     understood correctly)

	config: report error when script given for inappropriate interface type
	This fixes https://bugzilla.redhat.com/show_bug.cgi?id=638633

	Although scripts are not used by interfaces of type other than
	"ethernet" in qemu, due to the fact that the parser stores the script
	name in a union that is only valid when type is ethernet or bridge,
	there is no way for anyone except the parser itself to catch the
	problem of specifying an interface script for an inappropriate
	interface type (by the time the parsed data gets back to the code that
	called the parser, all evidence that a script was specified is
	forgotten).

	Since the parser itself should be agnostic to which type of interface
	allows scripts (an example of why: a script specified for an interface
	of type bridge is valid for xen domains, but not for qemu domains),
	the solution here is to move the script out of the union(s) in the
	DomainNetDef, always populate it when specified (regardless of
	interface type), and let the driver decide whether or not it is
	appropriate.

	Currently the qemu, xen, libxml, and uml drivers recognize the script
	parameter and do something with it (the uml driver only to report that
	it isn't supported). Those drivers have been updated to log a
	CONFIG_UNSUPPORTED error when a script is specified for an interface
	type that's inappropriate for that particular hypervisor.

	(NB: There was earlier discussion of solving this problem by adding a
	VALIDATE flag to all libvirt APIs that accept XML, which would cause
	the XML to be validated against the RNG files. One statement during
	that discussion was that the RNG shouldn't contain hypervisor-specific
	things, though, and a proper solution to this problem would require
	that (again, because a script for an interface of type "bridge" is
	accepted by xen, but not by qemu).

	build: drop check for ANSI compiler
	Using automake.git (will become 1.12 someday), I got this error:

	configure.ac:90: error: automatic de-ANSI-fication support has been removed
	/usr/local/share/aclocal-1.11a/protos.m4:13: AM_C_PROTOTYPES is expanded from...
	configure.ac:90: the top level
	autom4te: /usr/bin/m4 failed with exit status: 1

	In short, pre-C89 compilers are no longer a viable portability
	target.  Besides, our code base already requires C99, so worrying
	about pre-C89 seems pointless.

	seclabel: fix regression in libvirtd restart
	Commit b434329 has a logic bug: seclabel overrides don't set
	def->type, but the default value is 0 (aka static).  Restarting
	libvirtd would thus reject the XML for any domain with an
	override of <seclabel relabel='no'/> (which happens quite
	easily if a disk image lives on NFS), with a message:

	2012-01-04 22:29:40.949+0000: 6769: error : virSecurityLabelDefParseXMLHelper:2593 : XML error: security label is missing

	Fix the logic to never read from an override's def->type, and
	to allow a missing <label> subelement when relabel is no.  There's
	a lot of stupid double-negatives in the code (!norelabel) because
	of the way that we want the zero-initialized defaults to behave.

	Implement DNS SRV record into the bridge driver
	Hi,
	this is the fifth version of my SRV record for DNSMasq patch rebased
	for the current codebase to the bridge driver and libvirt XML file to
	include support for the SRV records in the DNS. The syntax is based on
	DNSMasq man page and tests for both xml2xml and xml2argv were added as
	well. There are some things written a better way in comparison with
	version 4, mainly there's no hack in tests/networkxml2argvtest.c and
	also the xPath context is changed to use a simpler query using the
	virXPathInt() function relative to the current node.

	Also, the patch is also fixing the networkxml2argv test to pass both
	checks, i.e. both unit tests and also syntax check.

	Please review,

	seclabel: honor device override in selinux
	This wires up the XML changes in the previous patch to let SELinux
	labeling honor user overrides, as well as affecting the live XML
	configuration in one case where the user didn't specify anything
	in the offline XML.

	I noticed that the logs contained messages like this:

	for all my domain images living on NFS.  But if we would just remember
	that on domain creation that we were unable to set a SELinux label (due to
	NFSv3 lacking labels, or NFSv4 not being configured to expose attributes),
	then we could avoid wasting the time trying to clear the label on
	domain shutdown.  This in turn is one less point of NFS failure,

	seclabel: extend XML to allow per-disk label overrides
	When doing security relabeling, there are cases where a per-file
	override might be appropriate.  For example, with a static label
	and relabeling, it might be appropriate to skip relabeling on a
	particular disk, where the backing file lives on NFS that lacks
	the ability to track labeling.  Or with dynamic labeling, it might
	be appropriate to use a custom (non-dynamic) label for a disk
	specifically intended to be shared across domains.

	The new XML resembles the top-level <seclabel>, but with fewer
	options (basically relabel='no', or <label>text</label>):

	<domain ...>
	  ...
	  <devices>
	    <disk type='file' device='disk'>
	      <source file='/path/to/image1'>
	        <seclabel relabel='no'/> <!-- override for just this disk -->
	      </source>
	      ...
	    </disk>
	    <disk type='file' device='disk'>
	      <source file='/path/to/image1'>
	        <seclabel relabel='yes'> <!-- override for just this disk -->
	          <label>system_u:object_r:shared_content_t:s0</label>
	        </seclabel>
	      </source>
	      ...
	    </disk>
	    ...
	  </devices>
	  <seclabel type='dynamic' model='selinux'>
	    <baselabel>text</baselabel> <!-- used for all devices without override -->
	  </seclabel>
	</domain>

	This patch only introduces the XML and documentation; future patches
	will actually parse and make use of it.  The intent is that we can
	further extend things as needed, adding a per-device <seclabel> in
	more places (such as the source of a console device), and possibly
	allowing a <baselabel> instead of <label> for labeling where we want
	to reuse the cNNN,cNNN pair of a dynamically labeled domain but a
	different base label.

	schema: rewrite seclabel rng to match code
	The RNG for <seclabel> was too strict - if it was present, then it
	had to have sub-elements, even if those didn't make sense for the
	given attributes.  Also, we didn't have any tests of <seclabel>
	parsing or XML output.

	In this patch, I added more parsing tests than output tests (since
	the output populates and/or reorders fields not present in certain
	inputs).  Making the RNG reliable is a precursor to using <seclabel>
	variants in more places in the XML in later patches.

	daemon: clean up daemonization
	Valgrind detected a pipe fd leak before the parent exits on success,
	introduced in commit 4296cea; by itself, the leak is not bad, since
	we immediately called _exit(), but we might as well be clean to make
	valgrind analysis easier.  Meanwhile, if the daemon grandchild detects
	an error, the parent failed to flush the error message before exiting.
	Also, we had the possibility of both parent and child returning to the
	caller, such that the user could see duplicated reports of failure
	from the two return paths.  And we might as well be robust to the
	(unlikely) situation of being started with stdin closed.

	* daemon/libvirtd.c (daemonForkIntoBackground): Use exit if an
	error message was generated, avoid fd leaks for valgrind's sake,
	avoid returning to caller in both parent and child, and don't

	Add New address type spapr-vio to domain.rng
	Original patch by Bharata. Updated to use {1,16} in spaprvioReg based
	on example from Eric Blake.

2011-12-21  Michael Ellerman  <michael@ellerman.id.au>

	Add address type for SPAPR VIO devices
	For QEMU PPC64 we have a machine type ("pseries") which has a virtual
	bus called "spapr-vio". We need to be able to create devices on this
	bus, and as such need a way to specify the address for those devices.

	This patch adds a new address type "spapr-vio", which achieves this.

	The addressing is specified with a "reg" property in the address
	definition. The reg is optional, if it is not specified QEMU will
	auto-assign an address for the device.

	qemu: Add a capability flag for -no-acpi
	Currently non-x86 guests must have <acpi/> defined in <features> to
	prevent libvirt from running qemu with -no-acpi. Although it works, it
	is a hack.

	Instead add a capability flag which indicates whether qemu understands
	the -no-acpi option. Use it to control whether libvirt emits -no-acpi.

	Current versions of qemu always display -no-acpi in their help output,

	Only add the timer when a callback is registered
	The lifetime of the virDomainEventState object is tied to
	the lifetime of the driver, which in stateless drivers is
	tied to the lifetime of the virConnectPtr.

	If we add & remove a timer when allocating/freeing the
	virDomainEventState object, we can get a situation where
	the timer still triggers once after virDomainEventState
	has been freed. The timeout callback can't keep a ref
	on the event state though, since that would be a circular
	reference.

	The trick is to only register the timer when a callback
	is registered with the event state & remove the timer
	when the callback is unregistered.

	The demo for the bug is to run

	  while true ; do date ; ../tools/virsh -q -c test:///default 'shutdown test; undefine test; dominfo test' ; done

	prior to this fix, it will frequently hang and / or
	crash, or corrupt memory

	Hide use of timers for domain event dispatch
	Currently all drivers using domain events need to provide a callback
	for handling a timer to dispatch events in a clean stack. There is
	no technical reason for dispatch to go via driver specific code. It
	could trivially be dispatched directly from the domain event code,
	thus removing tedious boilerplate code from all drivers

	Also fix the libxl & xen drivers to pass 'true' when creating the
	virDomainEventState, since they run inside the daemon & thus always
	expect events to be present.

	When registering a callback for a particular event some callers

	which is returned in the specific case of a user abort, while leaving

	Currently, on device detach, we parse given XML, find the device

	virsh: Add option to undefine storage with domains
	Add an option for virsh undefine command, to remove associated storage

	associated (libvirt managed ) storage volumes while undefining a domain.

	The new option --storage for the undefine command takes a string
	argument that consists of comma separated list of target or source path
	of volumes to be undefined. Volumes are removed after the domain has
	been successfully undefined,

	If a volume is not part of a storage pool, the user is warned to remove
	the volume in question himself.

	Option --wipe-storage may be specified along with this, that ensures
	the image is wiped before removing.

	Option --remove-all-storage enables the user to remove all storage. The
	name is chosen long as the users should be aware what they're about to
	do.

	qemu: Fix race between async and query jobs
	If an async job run on a domain will stop the domain at the end of the
	job, a concurrently run query job can hang in qemu monitor and nothing
	can be done with that domain from this point on. An attempt to start
	such domain results in "Timed out during operation: cannot acquire state
	change lock" error.

	However, quite a few things have to happen at the right time... There
	must be an async job running which stops a domain at the end. This race
	was reported with dump --crash but other similar jobs, such as
	(managed)save and migration, should be able to trigger this bug as well.
	While this async job is processing its last monitor command, that is a
	query-migrate to which qemu replies with status "completed", a new
	libvirt API that results in a query job must arrive and stay waiting
	until the query-migrate command finishes. Once query-migrate is done but
	before the async job closes qemu monitor while stopping the domain, the
	other thread needs to wake up and call qemuMonitorSend to send its
	command to qemu. Before qemu gets a chance to respond to this command,
	the async job needs to close the monitor. At this point, the query job
	thread is waiting for a condition that no-one will ever signal so it
	never finishes the job.

	qemu: Do not free the device from activePciHostdevs if it's in use
	* src/qemu/qemu_hostdev.c (qemuDomainReAttachHostdevDevices):
	pciDeviceListFree(pcidevs) in the end free()s the device even if
	it's in use by other domain, which can cause a race.

	How to reproduce:

	<script>

	virsh nodedev-dettach pci_0000_00_19_0
	virsh start test
	virsh attach-device test hostdev.xml
	virsh start test2

	for i in {1..5}; do
	        echo "[ -- ${i}th time --]"
	        virsh nodedev-reattach pci_0000_00_19_0
	done

	echo "clean up"
	virsh destroy test
	virsh nodedev-reattach pci_0000_00_19_0
	</script>

	Device pci_0000_00_19_0 dettached

	Domain test started

	Device attached successfully

	error: Failed to start domain test2
	error: Requested operation is not valid: PCI device 0000:00:19.0 is in use by domain test

	[ -- 1th time --]
	Device pci_0000_00_19_0 re-attached

	Device pci_0000_00_19_0 re-attached

	Device pci_0000_00_19_0 re-attached

	[ -- 4th time --]
	Device pci_0000_00_19_0 re-attached

	[ -- 5th time --]
	Device pci_0000_00_19_0 re-attached

	clean up
	Domain test destroyed

	Device pci_0000_00_19_0 re-attached

	The patch also fixes another problem, there won't be error like
	"qemuDomainReAttachHostdevDevices: Not reattaching active
	device 0000:00:19.0" in daemon log if some device is in active.
	As pciResetDevice and pciReattachDevice won't be called for

	qemu: Honor the original properties of PCI device when detaching
	This patch fixes two problems:
	    1) The device will be reattached to host even if it's not
	       managed, as there is a "pciDeviceSetManaged".
	    2) The device won't be reattached to host with original
	       driver properly. As it doesn't honor the device original
	       properties which are maintained by driver->activePciHostdevs.

	qemu: Disable EOF processing during qemuDomainDestroy
	When destroying a domain qemuDomainDestroy kills its qemu process and
	starts a new job, which means it unlocks the domain object and locks it
	again after some time. Although the object is usually unlocked for a
	pretty short time, chances are another thread processing an EOF event on
	qemu monitor is able to lock the object first and does all the cleanup
	by itself. This leads to wrong shutoff reason and lifecycle event detail
	and virDomainDestroy API incorrectly reporting failure to destroy an
	inactive domain.

	now-deprecated qemu machine type ("fedora-13", which was only ever
	valid for Fedora builds of qemu). Although strictly speaking it's not
	necessary to replace it with an actual supported qemu machine type
	(since the xml in question is never actually sent to qemu), this patch
	changes it to the actually-supported "pc-0.13" just for general
	tidiness. (Also, on some Fedora builds which contain a special patch
	to rid the world of "fedora-13", having it mentioned in the test suite
	will cause make check to fail.)

	network: don't add iptables rules for externally managed networks
	This patch addresses https://bugzilla.redhat.com/show_bug.cgi?id=760442

	When a network has any forward type other than route, nat or none, the
	network configuration should be done completely external to libvirt -
	libvirt only uses these types to allow configuring guests in a manner
	that isn't tied to a specific host (all the host-specific information,
	in particular interface names, port profile data, and bandwidth
	configuration is in the network definition, and the guest
	configuration only references it).

	Due to a bug in the bridge network driver, libvirt was adding iptables
	rules for networks with forward type='bridge' etc. any time libvirtd
	was restarted while one of these networks was active.

	This patch eliminates that error by only "reloading" iptables rules if
	forward type is route, nat, or none.

	(we may not post the DHCP snooping patches for 0.9.9, though)

	Commit ecd8725 tried to silence a spurious warning on the initial
	libvirt install, and commit ba6cbb1 tried to fix up the logic to the
	correct Fedora version, but the warning was still present due to a
	logic bug: since %{fedora} and %{rhel} are never simulatanously
	set, then 0%{rhel} <= 6 made the %if always true.  Checking for
	minimum versions (via >=) is okay, but checking for maximum versions
	(via <=) requires a prerequisite test that the platform being tested
	is non-zero.

	Also fix a bogus setting of with_libxl (although we previously
	hard-code with_libxl to 0 for rhel earlier in the file, so this
	was not as severe a bug).

	* libvirt.spec.in (with_cgconfig): Don't enable cgconfig on F16.

	spec: make it easier to autoreconf when building rpm
	Over time, Fedora and RHEL RPMs have often backported upstream
	patches that touched configure.ac and/or Makefile.am; this
	necessitates rerunning the autotools for the patch to be effective.
	Making this a one-liner spec tweak will make it easier for future
	backports to pull patches without having to find all the places
	to touch to properly use the autotools.  Meanwhile, there have been
	historical instances where an update in the autotools caused FTBFS
	situations, so this is not on by default.

	* libvirt.spec.in (enable_autotools): New variable, default off.
	(BuildRequires): Conditionally add autotools.
	(%build): Conditionally use them before configure.
	* mingw32-libvirt.spec.in: Likewise.

	Clean up qemuBuildCommandLine to remove x86-specific
	 assumptions from generic code.

	This implements the minimal set of changes needed in libvirt to launch a
	PowerPC-KVM based guest.
	It removes x86-specific assumptions about choice of serial driver backend
	from generic qemu guest commandline generation code.
	It also restricts the ACPI capability to be available for an x86 or
	x86_64 domain.
	This is not a complete solution -- it still does not guarantee libvirt
	the capability to flag non-supported options in guest XML. (Eg, an ACPI
	specification in a PowerPC guest XML will still get processed, even
	though qemu-system-ppc64 does not support it while qemu-system-x86_64 does.)
	This drawback exists because libvirt falls back on qemu to query supported
	features, and qemu '-h' blindly lists all capabilities -- irrespective
	of whether they are available while emulating a given architecture or not.
	The long-term solution would be for qemu to list out capabilities based
	on architecture and platform -- so that libvirt can cleanly make out what
	devices are supported on an arch (say 'ppc64') and platform (say, 'mac99').

2011-12-08  Prerna Saxena  <prerna@linux.vnet.ibm.com>

	Add support for ppc64 qemu
	This enables libvirt to select the correct qemu binary (qemu-system-ppc64)
	for a guest vm based on arch 'ppc64'.
	Also, libvirt is enabled to correctly parse the list of supported PowerPC
	CPUs, generated by running 'qemu-system-ppc64 -cpu ?'

	Use sysfs to gather host topology, in place of
	 /proc/cpuinfo

	Libvirt at present depends on /proc/cpuinfo to gather host
	details such as CPUs, cores, threads, etc. This is an architecture-
	dependent approach. An alternative is to use 'Sysfs', which provides
	a platform-agnostic interface to parse host CPU topology.

	spec: don't use chkconfig --list

	Fix updating of haveTheBuck in RPC client to be race-free
	When one thread passes the buck to another thread, it uses
	virCondSignal to wake up the target thread. The variable
	'haveTheBuck' is not updated in a race-free manner when
	this occurs. The current thread sets it to false, and the
	woken up thread sets it to true. There is a window where
	a 3rd thread can come in and grab the buck.

	Even if this didn't lead to crashes & deadlocks, this would
	still result in unfairness in the buckpassing algorithm.

	A better solution is to *never* set haveTheBuck to false
	when we're passing the buck. Only set it to false when there
	is no further thread waiting for the buck.

	qemu: Rework handling of shutdown event
	When QEMU guest finishes its shutdown sequence, qemu stops virtual CPUs
	and when started with -no-shutdown waits for us to kill it using
	SGITERM. Since QEMU is flushing its internal buffers, some time may pass
	before QEMU actually dies. We mistakenly used "paused" state (and
	events) for this which is quite confusing since users may see a domain
	going to pause while they expect it to shutdown. Since we already have
	"shutdown" state with "the domain is being shut down" semantics, we
	should use it for this state.

	However, the state didn't have a corresponding event so I created one
	and called its detail as VIR_DOMAIN_EVENT_SHUTDOWN_FINISHED (guest OS
	finished its shutdown sequence) with the intent to add
	VIR_DOMAIN_EVENT_SHUTDOWN_STARTED in the future if we have a
	sufficiently capable guest agent that can notify us when guest OS starts
	to shutdown.

	build: require more tools from maintainers
	We want our tarballs to be complete - this means that any
	generated file that gets shipped as part of the tarball so that
	ordinary users don't have to rebuild it must be something
	that the maintainer can generate.  There have been various
	reports of random build failures when using libvirt.git
	instead of a tarball, and often it is due to missing a
	maintainer-specific tool to produce one of these generated
	files.  This patch raises the bar for what you must have
	installed to build libvirt.git, but does not impact what
	you can get away with for building tarballs.

	build: fix build at -O2 on rawhide
	I had previously tested commit 059d746 with -O intentionally omitted
	from my CFLAGS; but that means that I missed out on this warning
	from gcc 4.6.2 when optimizations are enabled:

	util/buf.c: In function 'virBufferGetIndent':
	util/buf.c:86:1: error: function might be candidate for attribute 'pure' [-Werror=suggest-attribute=pure]

	While it is probably a good idea to add the attributes and silence
	this warning, it's also invasive; 'make -k' found more than 75 such
	complaints.  And it doesn't help that gcc 4.6.2 is still buggy
	(coreutils reported a case where gcc 4.6.2 incorrectly suggested
	marking a function pure that incremented a global variable; fixed
	in gcc 4.7).  So the best fix for now is to disable the warning.

	It also doesn't help that I stumbled across another problem - gcc
	documents that -Wsuggest-attribute=pure only warns if you use -O,
	or if you use -fipa-pure-const.  But in practice, when I omitted -O
	but added -fipa-pure-const, the warnings are fickle - I got warnings
	for simple compilation that disappeared when I also added -fPIC.
	And the way libtool compiles things is with -fPIC first, then without
	-fPIC but with errors sent to /dev/null - which meant that without
	disabling -Wsuggest-attribute=pure, I got a compile error with no
	message.  :(  See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10197

	* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Silence
	-Wsuggest-attribute warnings for now.

	build: fix 'make dist' without dtrace
	probes.h can only be generated on Linux, and then only with dtrace
	installed.  If it is part of the tarball, then either 'make dist'
	will fail if you don't have that setup, or we would have to start
	keeping probes.h in libvirt.git.  Since we only need it to be
	generated when dtrace is in use, it's better to avoid shipping
	it in the first place, and avoid tracking it in git.

	Meanwhile, there is a build dependency - since the RPC code is
	generated, it can be built early; but when dtrace is enabled, we
	must ensure probes.h is built even earlier.  Commit 1afcfbdd tried
	to fix this, but did so in a way that added probes.h into the
	tarball, and broke VPATH as well.  Commit ecbca767 fixed VPATH,
	but didn't fix the more fundamental problem.  This patch solves
	the issue by adding a dependency instead.

	Tested with 'make dist' in a clean VPATH builds, for both
	'./configure --without-dtrace' and './configure --with-dtrace';
	all configurations were able to correctly build a tarball, and
	the dtrace configuration no longer sticks probes.h in the tarball.

	* src/Makefile.am (REMOTE_DRIVER_GENERATED): Don't ship probes.h;
	rather, make it a dependency.

	spec: mark directories in /var/run as ghosts
	We have several directories that are created on the fly, and which
	only contain state relevant to a running libvirtd process (all
	located in /var/run).  Since the directories are created as needed,
	and make no sense without a running libvirtd, we want them deleted
	if libvirt is uninstalled.  And in F15 and newer, /var/run is on
	tmpfs (forcing us to recreate on the fly); which means that someone
	trying to verify a complete rpm will fail if the directory does not
	currently exist because libvirtd has not been started since boot.
	The solution, then, is to mark the directories as %ghost, so that
	rpm knows that we own them and will clean it up if libvirt is
	uninstalled, but will no longer create the directory for us at
	install, nor complain at verify time if the directory does not exist.

	See https://bugzilla.redhat.com/show_bug.cgi?id=656611.

	* libvirt.spec.in (%files): Add %ghost to temporary directories

	qemu: filter blkio 0-device-weight at two other places
	filter 0-device-weight when:

	  - getting blkio parameters with --config
	  - starting up a domain

	When testing with blkio, I found these issues:

	  (dom is down)
	  virsh blkiotune dom --device-weights /dev/sda,300,/dev/sdb,500
	  virsh blkiotune dom --device-weights /dev/sda,300,/dev/sdb,0
	  virsh blkiotune dom
	  weight         : 800
	  device_weight  : /dev/sda,200,/dev/sdb,0

	  # issue 1: shows 0 device weight of /dev/sdb that may confuse user

	  (continued)
	  virsh start dom

	  # issue 2: If /dev/sdb doesn't exist, libvirt refuses to bring the
	  # dom up because it wants to set the device weight to 0 of a
	  # non-existing device. Since 0 means no weight-limit, we really don't
	  # have to set it.

2011-12-01  Eric Blake  <eblake@redhat.com>

	qemu: amend existing table of device weights
	Prior to this patch, for a running dom, the commands:

	$ virsh blkiotune dom --device-weights /dev/sda,502,/dev/sdb,498
	$ virsh blkiotune dom --device-weights /dev/sda,503
	$ virsh blkiotune dom
	weight         : 500
	device_weight  : /dev/sda,503

	claim that /dev/sdb no longer has a non-default weight, but
	directly querying cgroups says otherwise:

	$ cat /cgroup/blkio/libvirt/qemu/dom/blkio.weight_device
	8:0     503
	8:16    498

	After this patch, an explicit 0 is required to remove a device path
	from the XML, and omitting a device path that was previously
	specified leaves that device path untouched in the XML, to match
	cgroups behavior.

	* src/qemu/qemu_driver.c (parseBlkioWeightDeviceStr): Rename...
	(qemuDomainParseDeviceWeightStr): ...and use correct type.
	(qemuDomainSetBlkioParameters): After parsing string, modify
	rather than replacing existing table.

	conf: reject duplicate paths in device weights
	The next patch will make it possible to have virDomainSetBlkioParameters
	leave device weights unchanged if they are not mentioned in the incoming
	string, but this only works if the list of block weights does not allow
	duplicate paths.  Technically, a user can still confuse libvirt by
	passing alternate spellings that resolve to the same device, but it
	is not worth worrying about working around that kind of abuse.

	paths.

	Introduce a new internal API which is async signal safe.

	  virTimeMillisNowRaw replacement for gettimeofday. Uses clock_gettime

	                      gettimeofday

	  virTimeFieldsThenRaw into a broken out set of fields. No localtime()
	                       replacement is provided, because converting to
	                       local time is not practical with only async signal
	                       safe APIs.

	  virTimeStringNowRaw  replacements for strftime() which print a timestamp
	  virTimeStringThenRaw into a string, using a pre-determined format, with
	                       a fixed size buffer (VIR_TIME_STRING_BUFLEN)

	blkiotune: add interface for blkiotune.device_weight
	This adds per-device weights to <blkiotune>.  Note that the

	Add virsh command to initiate suspend on the host
	Add a new command 'nodesuspend' to perform a timed suspend on the host.

2011-11-29  Srivatsa S. Bhat  <srivatsa.bhat@linux.vnet.ibm.com>

	Implement the core API to suspend/resume the host
	Add the core functions that implement the functionality of the API.
	Suspend is done by using an asynchronous mechanism so that we can return
	the status to the caller before the host gets suspended. This asynchronous
	operation is achieved by suspending the host in a separate thread of
	execution. However, returning the status to the caller is only best-effort,
	but not guaranteed.

	To resume the host, an RTC alarm is set up (based on how long we want to
	suspend) before suspending the host. When this alarm fires, the host
	gets woken up.

	Suspend-to-RAM operation on a host running Linux can take upto more than 20
	seconds, depending on the load of the system. (Freezing of tasks, an operation
	preceding any suspend operation, is given up after a 20 second timeout).
	And Suspend-to-Disk can take even more time, considering the time required
	for compaction, creating the memory image and writing it to disk etc.
	So, we do not allow the user to specify a suspend duration of less than 60
	seconds, to be on the safer side, since we don't want to prematurely declare
	failure when we only had to wait for some more time.

2011-11-29  Srivatsa S. Bhat  <srivatsa.bhat@linux.vnet.ibm.com>

	Add the remote protocol implementation for virNodeSuspendForDuration
	Implement the remote protocol for virNodeSuspendForDuration() API.

	Add a public API to invoke suspend/resume on the host
	Implement the public definitions for the new API
	virNodeSuspendForDuration() which will be subsequently used to
	do a timed suspend on the host.

	Add 'Hybrid-Suspend' power management discovery for the host
	Some systems support a feature known as 'Hybrid-Suspend', apart from the
	usual system-wide sleep states such as Suspend-to-RAM (S3) or Suspend-to-Disk
	(S4). Add the functionality to discover this power management feature and
	export it in the capabilities XML under the <power_management> tag.

	Fix version numbers for isAlive and setKeepAlive driver APIs

	build: Properly generate and check virkeepaliveprotocol-structs
	This fixes make dist broken by recent keepalive series

	examples: Use virConnectOpenAuth in events-c

	qemu: Cancel p2p migration when connection breaks
	If a connection to destination host is lost during peer-to-peer
	migration (because keepalive protocol timed out), we won't be able to
	finish the migration and it doesn't make sense to wait for qemu to
	transmit all data. This patch automatically cancels such migration
	without waiting for virDomainAbortJob to be called.

	qemu: Add support for keepalive messages during p2p migration

	Add keepalive support into domain-events examples

	Implement virConnectIsAlive in all drivers

	Introduce virConnectIsAlive API
	This API can be used to check if the socket associated with
	virConnectPtr is still open or it was closed (probably because keepalive
	protocol timed out). If there the connection is local (i.e., no socket
	is associated with the connection, it is trivially always alive.

	Implement keepalive protocol in remote driver

	Implement keepalive protocol in libvirt daemon

	virsh: Always run event loop
	Since virsh already implements event loop, it has to also run it. So far
	the event loop was only running during virsh console command.

	Introduce virConnectSetKeepAlive
	virConnectSetKeepAlive public API can be used by a client connecting to
	remote server to start using keepalive protocol. The API is handled
	directly by remote driver and not transmitted over the wire to the
	server.

	Implement common keepalive handling
	These APIs are used by both client and server RPC layer to handle
	processing of keepalive messages.

	Define keepalive protocol
	The keepalive program has two procedures: PING, and PONG.
	Both are used only in asynchronous messages and the sender doesn't wait
	for any reply. However, the party which receives PING messages is
	supposed to react by sending PONG message the other party, but no
	explicit binding between PING and PONG messages is made. For backward
	compatibility neither server nor client are allowed to send keepalive
	messages before checking that remote party supports them.

	This patch exports KVM Host Power Management capabilities as XML so that

	If either of them are supported, then a new tag "<power_management>" is
	introduced in the XML under the <host> tag.

	However in case the query to check for power management features succeeded,
	but the host does not support any such feature, then the XML will contain
	an empty <power_management/> tag. In the event that the PM query itself
	failed, the XML will not contain any "power_management" tag.

	tests: avoid xend ABRT crash report
	I installed the xen development packages on my non-Xen F16 machine
	in order to compile-test xen code and ensure we don't break things
	on that front, but being a non-xen machine, /usr/sbin/xend is
	obviously not running.  Unfortunately, xen-4.1.2-1.fc16 has a bug
	where merely trying to probe xend status on a non-xen kernel causes
	xend to issue an ABRT crash report:

	https://bugzilla.redhat.com/show_bug.cgi?id=728696

	Even though libvirt (correctly) skips the test, the xend crash report
	is unnecessary noise.  Fix this by first filtering out non-xen
	kernels even before attempting to probe xend.  The test still runs
	and passes on a RHEL 5 xen kernel after this patch.

	build: fix accidental POTFILES.in regression
	The original patch for commit 4789fb2 considered renaming a file,
	then backed out the name change, but forgot to back out the POTFILES.in
	change, resulting in 'make syntax-check' failure.

	Add test cases for parsing of list values
	This patch adds test cases for parsing of parameters with
	multiple occurrances of the same name.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Extend NWFilter parameter parser to cope with lists of values
	This patch modifies the NWFilter parameter parser to support multiple
	elements with the same name and to internally build a list of items.
	An example of the XML looks like this:

	        <parameter name='TEST' value='10.1.2.3'/>
	        <parameter name='TEST' value='10.2.3.4'/>
	        <parameter name='TEST' value='10.1.1.1'/>

	The list of values is then stored in the newly introduced data type
	virNWFilterVarValue.

	The XML formatter is also adapted to print out all items in alphabetical
	order sorted by 'name'.

	This patch also fixes a bug in the XML schema on the way.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Create rules for each member of a list
	This patch extends the NWFilter driver for Linux (ebiptables) to create
	rules for each member of a previously introduced list. If for example
	an attribute value (internally) looks like this:

	IP = [10.0.0.1, 10.0.0.2, 10.0.0.3]

	then 3 rules will be generated for a rule accessing the variable 'IP',
	one for each member of the list. The effect of this is that this now
	allows for filtering for multiple values in one field. This can then be
	used to support for filtering/allowing of multiple IP addresses per
	interface.

	An iterator is introduced that extracts each member of a list and
	puts it into a hash table which then is passed to the function creating
	a rule. For the above example the iterator would cause 3 loops.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Rework value part of name-value pairs
	NWFilters can be provided name-value pairs using the following
	XML notation:

	      <filterref filter='xyz'>
	        <parameter name='PORT' value='80'/>
	        <parameter name='VAL' value='abc'/>
	      </filterref>

	The internal representation currently is so that a name is stored as a
	string and the value as well. This patch now addresses the value part of it
	and introduces a data structure for storing a value either as a simple
	value or as an array for later support of lists.

	This patch adjusts all code that was handling the values in hash tables
	and makes it use the new data type.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Documentation about chains' priorities, lists of elements etc.
	This patch adds several aspects of documentation about the network filtering
	system:

	- chains, chains' priorities and chains' default priorities
	- talks about lists of elements, i.e., a variable assigned multiple values
	  (part of already ACK-ed series)
	- already mentions the vlan, stp and mac chains added later on
	  (https://www.redhat.com/archives/libvir-list/2011-October/msg01238.html)
	- mentions limitations of vlan filtering (when sent by VM) on Linux systems

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Add test cases
	Add test case for the chain names with known prefixes and the chain
	priority.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Interleave jumping into chains with filtering rules in 'root' table
	The previous patch extends the priority of filtering rules into negative
	numbers. We now use this possibility to interleave the jumping into
	chains with filtering rules to for example create the 'root' table of
	an interface with the following sequence of rules:

	Bridge chain: libvirt-I-vnet0, entries: 6, policy: ACCEPT
	-p IPv4 -j I-vnet0-ipv4
	-p ARP -j I-vnet0-arp
	-p ARP -j ACCEPT 
	-p 0x8035 -j I-vnet0-rarp
	-p 0x835 -j ACCEPT 
	-j DROP 

	The '-p ARP -j ACCEPT' rule now appears between the jumps.
	Since the 'arp' chain has been assigned priority -700 and the 'rarp'
	chain -600, the above ordering can now be achieved with the following
	rule:

	  <rule action='accept' direction='out' priority='-650'>
	    <mac protocolid='arp'/>
	  </rule>

	This patch now sorts the commands generating the above shown jumps into
	chains and interleaves their execution with those for generating rules.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Extend rule priorities into negative numbers
	So far rules' priorities have only been valid in the range [0,1000].
	Now I am extending their priority into the range [-1000, 1000] for subsequently
	being able to sort rules and the access of (jumps into) chains following
	priorities.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Enable chains with names having a known prefix
	This patch enables chains that have a known prefix in their name.
	Known prefixes are: 'ipv4', 'ipv6', 'arp', 'rarp'. All prefixes
	are also protocols that can be evaluated on the ebtables level.

	Following the prefix they will be automatically connected to an interface's
	'root' chain and jumped into following the protocol they evaluate, i.e.,
	a table 'arp-xyz' will be accessed from the root table using

	ebtables -t nat -A <iface root table> -p arp -j I-<ifname>-arp-xyz

	thus generating a 'root' chain like this one here:

	Bridge chain: libvirt-O-vnet0, entries: 5, policy: ACCEPT
	-p IPv4 -j O-vnet0-ipv4
	-p ARP -j O-vnet0-arp
	-p 0x8035 -j O-vnet0-rarp
	-p ARP -j O-vnet0-arp-xyz
	-j DROP 

	where the chain 'arp-xyz' is accessed for filtering of ARP packets.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Extend the filter XML to support priorities of chains
	This patch extends the filter XML to support priorities of chains
	in the XML. An example would be:

	<filter name='allow-arpxyz' chain='arp-xyz' priority='200'>
	[...]
	</filter>

	The permitted values for priorities are [-1000, 1000].
	By setting the priority of a chain the order in which it is accessed
	from the interface root chain can be influenced.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Use the actual names of chains in data structure
	Use the name of the chain rather than its type index (enum).
	This pushes the later enablement of chains with user-given names
	into the XML parser. For now we still only allow those names that
	are well known ('root', 'arp', 'rarp', 'ipv4' and 'ipv6').

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Use scripting for cleaning and renaming of chains
	Use scripts for the renaming and cleaning up of chains. This allows us to get
	rid of some of the code that is only capable of renaming and removing chains
	whose names are hardcoded.

	A shell function 'collect_chains' is introduced that is given the name
	of an ebtables chain and then recursively determines the names of all
	chains that are accessed from this chain and its sub-chains using 'jumps'.

	The resulting list of chain names is then used to delete all the found
	chains by first flushing and then deleting them.

	The same function is also used for renaming temporary filters to their final
	names.

	I tested this with the bash and dash as script interpreters.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Make filter creation in root table more flexible
	Use the previously introduced chain priorities to sort the chains for access
	from an interface's 'root' table and have them created in the proper order.
	This gets rid of a lot of code that was previously creating the chains in a 
	more hardcoded way.

	To determine what protocol a filter is used for evaluation do prefix-
	matching, i.e., the filter 'arp' is used to filter for the 'arp' protocol,
	'ipv4' for the 'ipv4' protocol and 'arp-xyz' will also be used to filter
	for the 'arp' protocol following the prefix 'arp' in its name.

2011-11-19  Stefan Berger  <stefanb@linux.vnet.ibm.com>

	Introduce an internal priority for chains
	For better handling of the sorting of chains introduce an internally used
	priority. Use a lookup table to store the priorities. For now their actual
	values do not matter just that the values cause the chains to be properly
	sorted through changes in the following patches. However, the values are
	chosen as negative so that once they are sorted along with filtering rules
	(whose priority may only be positive for now) they will always be instantiated
	before them (lower values cause instantiation before higher values). This
	is done to maintain backwards compatibility.

	Add function to get hash table's key/value pairs
	Add a function to the virHashTable for getting an array of the hash table's
	key-value pairs and have the keys (optionally) sorted.

	Add support for systemd init service
	This patch adds support for a systemd init service for libvirtd
	and libvirt-guests. The libvirtd.service is *not* written to use
	socket activation, since we want libvirtd to start on boot so it
	can do guest auto-start.

	The libvirt-guests.service is pretty lame, just exec'ing the
	original init script for now. Ideally we would factor out the
	functionality, into some shared tool.

	Instead of

	  ./configure --with-init-script=redhat

	You can now do

	  ./configure --with-init-script=systemd

	Or better still:

	  ./configure --with-init-script=systemd+redhat

	We can also now support install of the upstart init script

	* configure.ac: Add systemd, and systemd+redhat options to
	  --with-init-script option
	* daemon/Makefile.am: Install systemd services
	* daemon/libvirtd.sysconf: Add note about unused env variable
	  with systemd
	* daemon/libvirtd.service.in: libvirtd systemd service unit
	* libvirt.spec.in: Add scripts to installing systemd services
	  and migrating from legacy init scripts
	* tools/Makefile.am: Install systemd services
	* tools/libvirt-guests.init.sh: Rename to tools/libvirt-guests.init.in
	* tools/libvirt-guests.service.in: systemd service unit

	snapshot: refuse to generate names for non-regular backing files
	For whatever reason, the kernel allows you to create a regular
	file named /dev/sdc.12345; although this file will disappear the
	next time devtmpfs is remounted.  If you let libvirt generate
	the name of the external snapshot for a disk image originally
	using the block device /dev/sdc, then the domain will be rendered
	unbootable once the qcow2 file is lost on the next devtmpfs
	remount.  In this case, the user should have used 'virsh
	snapshot-create --xmlfile' or 'virsh snapshot-create-as --diskspec'
	to specify the name for the qcow2 file in a sane location, rather
	than relying on libvirt generating a name that is most likely to
	be wrong.  We can help avoid naive mistakes by enforcing that
	the user provide the external name for any backing file that is
	not a regular file.

	* src/conf/domain_conf.c (virDomainSnapshotAlignDisks): Only
	generate names if backing file exists as regular file.

	virsh: add iface-bridge and iface-unbridge commands
	One of the top questions by libvirt users is how to create a host
	bridge device so that guests can be directly on the physical
	network. There are several example documents that explain how to do
	this manually, but following them often results in confusion and
	failure. virt-manager does a good job of creating a bridge based on an
	existing network device, but not everyone wants to use virt-manager.

	This patch adds a new command, iface-bridge that makes it just about
	as simple as possible to create a new bridge device based on an
	existing ethernet/vlan/bond device (including associating IP
	configuration with the bridge rather than the now-attached device),
	and start that new bridge up ready for action, eg:

	    virsh iface-bridge eth0 br0

	For symmetry's sake, it also adds a command to remove a device from a
	bridge, restoring the IP config to the now-unattached device:

	    virsh iface-unbridge br0

	(I had a short debate about whether to do "iface-unbridge eth0"
	instead, but that would involve searching through all bridge devices
	for the one that contained eth0, which seems like a bit too much
	trouble).

	NOTE: These two commands require that the netcf library be available
	on the host. Hopefully this will provide some extra incentive for
	people using suse, debian, ubuntu, and other similar systems to polish
	up (and push downstream) the ports to those distros recently pushed to
	the upstream netcf repo by Dan Berrange. Anyone interested in helping
	with that effort in any way should join the netcf-devel mailing list
	(subscription info at
	https://fedorahosted.org/mailman/listinfo/netcf-devel)

	During creation of the bridge, it's possible to specify whether or not
	the STP protocol should be started up on the bridge and, if so, how
	many seconds the bridge should squelch traffic from newly added
	devices while learning new topology (defaults are stp='on' and
	delay='0', which seems to usually work best for bridges used in the
	context of libvirt guests).

	There is also an option to not immediately start the bridge (and a
	similar option to not immediately start the un-attached device after
	destroying the bridge. Default is to start the new device, because in
	the case of iface-unbridge not starting is strongly discouraged as it
	will leave the system with no network connectivity on that interface
	(because it's necessary to destroy/undefine the bridge device before
	the unattached device can be defined), and it seemed better to make
	the option for iface-bridge behave consistently.

	NOTE TO THOSE TRYING THESE COMMANDS FOR THE FIRST TIME: to guard
	against any "unexpected" change to configuration, it is advisable to
	issue an "virsh iface-begin" command before starting any interface
	config changes, and "virsh iface-commit" only after you've verified
	that everything is working as you expect. If something goes wrong,
	you can always run "virsh iface-rollback" or reboot the system (which
	should automatically do iface-rollback).

	Aside from adding the code for these two functions, and the two
	entries into the command table, the only other change to virsh.c was
	to add the option name to vshCommandOptInterfaceBy(), because the
	iface-unbridge command names its interface option as "bridge".

	virsh.pod has also been updated with short descriptions of these two
	new commands.

	An <auth> member of the disk source xml specifies how librbd should

	API: add trivial qemu support for VIR_TYPED_PARAM_STRING
	Qemu will be the first driver to make use of a typed string in the
	next round of additions.  Separate out the trivial addition.

	* src/qemu/qemu_driver.c (qemudSupportsFeature): Advertise feature.
	(qemuDomainGetBlkioParameters, qemuDomainGetMemoryParameters)
	(qemuGetSchedulerParametersFlags, qemudDomainBlockStatsFlags):
	Allow typed strings flag where trivially supported.

2011-11-12  Eric Blake  <eblake@redhat.com>

	API: remote support for VIR_TYPED_PARAM_STRING
	Send and receive string typed parameters across RPC.  This also
	completes the back-compat mentioned in the previous patch - the
	only time we have an older client talking to a newer server is
	if RPC is in use, so filtering out strings during RPC prevents
	returning an unknown type to the older client.

	* src/remote/remote_protocol.x (remote_typed_param_value): Add
	another union value.
	* daemon/remote.c (remoteDeserializeTypedParameters): Handle
	strings on rpc.
	(remoteSerializeTypedParameters): Likewise; plus filter out
	strings when replying to older clients.  Adjust callers.
	* src/remote/remote_driver.c (remoteFreeTypedParameters)
	(remoteSerializeTypedParameters)
	(remoteDeserializeTypedParameters): Handle strings on rpc.
	* src/rpc/gendispatch.pl: Properly clean up typed arrays.
	* src/remote_protocol-structs: Update.
	Based on an initial patch by Hu Tao, with feedback from
	Daniel P. Berrange.

2011-11-12  Eric Blake  <eblake@redhat.com>

	API: add VIR_TYPED_PARAM_STRING
	This allows strings to be transported between client and server
	in the context of name-type-value virTypedParameter functions.
	For compatibility,

	    o new clients will not send strings to old servers, based on
	      a feature check
	    o new servers will not send strings to old clients without the
	      flag VIR_TYPED_PARAM_STRING_OKAY; this will be enforced at
	      the RPC layer in the next patch, so that drivers need not
	      worry about it in general.  The one exception is that
	      virDomainGetSchedulerParameters lacks a flags argument, so
	      it must not return a string; drivers that forward that
	      function on to virDomainGetSchedulerParametersFlags will
	      have to pay attention to the flag.
	    o the flag VIR_TYPED_PARAM_STRING_OKAY is set automatically,
	      based on a feature check (so far, no driver implements it),
	      so clients do not have to worry about it

	Future patches can then enable the feature on a per-driver basis.

	This patch also ensures that drivers can blindly strdup() field
	names (previously, a malicious client could stuff 80 non-NUL bytes
	into field and cause a read overrun).

	* src/libvirt_internal.h (VIR_DRV_FEATURE_TYPED_PARAM_STRING): New
	driver feature.
	* src/libvirt.c (virTypedParameterValidateSet)
	(virTypedParameterSanitizeGet): New helper functions.
	(virDomainSetMemoryParameters, virDomainSetBlkioParameters)
	(virDomainSetSchedulerParameters)
	(virDomainSetSchedulerParametersFlags)
	(virDomainGetMemoryParameters, virDomainGetBlkioParameters)
	(virDomainGetSchedulerParameters)
	(virDomainGetSchedulerParametersFlags, virDomainBlockStatsFlags):
	Use them.
	* src/util/util.h (virTypedParameterArrayClear): New helper
	function.
	* src/util/util.c (virTypedParameterArrayClear): Implement it.
	* src/libvirt_private.syms (util.h): Export it.
	Based on an initial patch by Hu Tao, with feedback from
	Daniel P. Berrange.

	qemu: fix domjobabort regression
	This reverts commit ef1065cf5ac; see also this bug report:
	https://bugzilla.redhat.com/show_bug.cgi?id=751900

	In qemu 0.15.1 and earlier, during migration to file, the
	qemu_savevm_state_begin and qemu_savevm_state_iterate methods
	will both process as much migration data as possible until either

	  1. The file descriptor returns EAGAIN
	  2. The bandwidth rate limit is reached

	If we set the rate limit to ULONG_MAX, test 2 never becomes true. We're
	passing a plain file descriptor to QEMU and POSIX does not support EAGAIN on
	regular files / block devices, so test 1 never becomes true either.

	In the 'virsh save --bypass-cache' case, we pass a pipe instead of a
	regular fd, but using a pipe adds I/O overhead, so always passing a
	pipe just so qemu can see EAGAIN doesn't seem nice.

	The ultimate fix needs to come from qemu - background migration must
	respect asynchronous abort requests, or else periodically return
	control to the main handling loop without an EAGAIN and without
	waiting to hit an insanely large amount of data.  But until a
	version of qemu is fixed to support "unlimited" data rates while
	still allowing cancellation, the best we can do is avoid the
	automatic use of unlimited rates from within libvirt (users can
	still explicitly change the migration rates, if they are aware that
	they are giving up the ability to cancel a job).

	Reverting the lone use of QEMU_DOMAIN_FILE_MIG_BANDWIDTH_MAX is
	the simplest patch; this slows migration back down to a default
	32M/sec cap, but also ensures that the main qemu processing loop
	will still be responsive to cancellation requests.  Hopefully
	upstream qemu will provide us a means of safely using unlimited
	speed, including a runtime probe of that capability.

	* src/qemu/qemu_migration.c (qemuMigrationToFile): Revert attempt
	to use unlimited migration bandwidth when migrating to file.

2011-11-12  Hu Tao  <hutao@cn.fujitsu.com>

	fix two bugs in bridge_driver.c
	steps to reproduce:

	1. having a network xml file(named default.xml) like this one:

	<network>
	  <name>default</name>
	  <uuid>c5322c4c-81d0-4985-a363-ad6389780d89</uuid>
	  <bridge name="virbr0" />
	  <forward/>
	  <ip address="192.168.122.1" netmask="255.255.255.0">
	    <dhcp>
	      <range start="192.168.122.2" end="192.168.122.254" />
	    </dhcp>
	  </ip>
	</network>

	in /etc/libvirt/qemu/networks/, and mark it as autostart:

	$ ls -l /etc/libvirt/qemu/networks/autostart
	total 0
	lrwxrwxrwx 1 root root 14 Oct 12 14:02 default.xml -> ../default.xml

	2. start libvirtd and the device virbr0 is not automatically up.

	The reason is that the function virNetDevExists is now returns 1 if
	the device exists, comparing to the former one returns 0 if the device
	exists. But with only this fix will cause a segmentation fault(the same
	steps as above)  that is fixed by the second chunk of code.

	nwfilter: avoid failure with noexec /tmp
	If /tmp is mounted with the noexec flag (common on security-conscious
	systems), then nwfilter will fail to initialize, because we cannot
	run any temporary script via virRun("/tmp/script"); but we _can_
	use "/bin/sh /tmp/script".  For that matter, using /tmp risks collisions
	with other unrelated programs; we already have /var/run/libvirt as a
	dedicated temporary directory for use by libvirt.

	* src/nwfilter/nwfilter_ebiptables_driver.c
	(ebiptablesWriteToTempFile): Use internal directory, not /tmp;
	drop attempts to make script executable; and detect close error.
	(ebiptablesExecCLI): Switch to virCommand, and invoke the shell to
	read the script, rather than requiring an executable script.

	Make all brXXX APIs raise errors, instead of returning errnos
	Currently every caller of the brXXX APIs has to store the returned
	errno value and then raise an error message. This results in

	hard to distinguish different scenarios from 1 errno value.

2011-11-10  Daniel P. Berrange  <berrange@redhat.com>

	Remove 'brControl' object
	The bridge management APIs in src/util/bridge.c require a brControl
	object to be passed around. This holds the file descriptor for the
	control socket. This extra object complicates use of the API for
	only a minor efficiency gain, which is in turn entirely offset by
	the need to fork/exec the brctl command for STP configuration.

	This patch removes the 'brControl' object entirely, instead opening
	the control socket & closing it again within the scope of each method.

	The parameter names for the APIs are also made to consistently use
	'brname' for bridge device name, and 'ifname' for an interface
	device name. Finally annotations are added for non-NULL parameters
	and return check validation

	* src/util/bridge.c, src/util/bridge.h: Remove brControl object
	  and update API parameter names & annotations.

	build: allow for local gnulib diffs
	Commit f7bd00c12 pulled in a gnulib module that fails to compile
	on mingw.  While it would be nice to pull in a newer version of
	.gnulib that fixes this, it is difficult to backport any .gnulib
	update to older releases.  So, it makes sense to take advantage
	of gnulib-tool's ability to support local diffs, where we can
	apply specific diffs in our use of gnulib without waiting for
	upstream gnulib to pick up those changes, as well as avoiding
	a wholesale .gnulib update.  The existence of local diffs will
	also make it easier to backport fixes against a tarball (as long
	as a tarball and libvirt.git share the same .gnulib commit, then
	the tarball can be patched by applying the same local diffs as
	a post-release libvirt.git commit, without having to rerun an
	entire gnulib-tool bootstrap).

	This patch introduces the framework for supporting local diffs,
	without actually introducing any.

	* bootstrap.conf (local_gl_dir): New variable.
	* autogen.sh (bootstrap_hash): Hash any local diffs, to force a
	re-bootstrap if just diffs change.
	* cfg.mk (_update_required): Likewise.

	build: fix build on platforms without ptsname_r
	MacOS lacks ptsname_r, and gnulib doesn't (yet) provide it.
	But we can avoid it altogether, by using gnulib openpty()
	instead.  Note that we do _not_ want the pt_chown module;
	gnulib uses it only to implement a replacement openpty() if
	the system lacks both openpty() and granpt(), but all
	systems that we currently port to either have at least one of
	openpty() and/or grantpt(), or lack ptys altogether.  That is,
	we aren't porting to any system that requires us to deal with
	the hassle of installing a setuid pt_chown helper just to use
	gnulib's ability to provide openpty() on obscure platforms.

	* .gnulib: Update to latest, for openpty fixes

	Fix sending/receiving of FDs when stream returns EAGAIN
	The code calling sendfd/recvfd was mistakenly assuming those
	calls would never block. They can in fact return EAGAIN and
	this is causing us to drop the client connection when blocking
	ocurrs while sending/receiving FDs.

	Fixing this is a little hairy on the incoming side, since at
	the point where we see the EAGAIN, we already thought we had
	finished receiving all data for the packet. So we play a little
	trick to reset bufferOffset again and go back into polling for
	more data.

	* src/rpc/virnetsocket.c, src/rpc/virnetsocket.h: Update

	Add support for multiple consoles in LXC
	Currently the LXC controller only supports setup of a single
	text console. This is wired up to the container init's stdio,
	as well as /dev/console and /dev/tty1. Extending support for
	multiple consoles, means wiring up additional PTYs to /dev/tty2,
	/dev/tty3, etc, etc. The LXC controller is passed multiple open
	file handles, one for each console requested.

	  all the /dev/ttyN links required to symlink to /dev/pts/NN
	* src/lxc/lxc_container.h: Open more container side /dev/pts/NN
	  devices, and adapt event loop to handle I/O from all consoles

2011-11-03  Daniel P. Berrange  <berrange@redhat.com>

	Rewrite LXC I/O forwarding to use main event loop
	The current I/O code for LXC uses a hand crafted event loop
	to forward I/O between the container & host app, based on
	epoll to handle EOF on PTYs. This event loop is not easily
	extensible to add more consoles, or monitor other types of
	file descriptors.

	Remove the custom event loop and replace it with a normal
	libvirt event loop. When detecting EOF on a PTY, disable
	the event watch on that FD, and fork off a background thread
	that does a edge-triggered epoll() on the FD. When the FD
	finally shows new incoming data, the thread re-enables the
	watch on the FD and exits.

	When getting EOF from a read() on the PTY, the existing code
	would do waitpid(WNOHANG) to see if the container had exited.
	Unfortunately there is a race condition, because even though
	the process has closed its stdio handles, it might still
	exist.

	To deal with this the new event loop uses a SIG_CHILD handler
	to perform the waitpid only when the container is known to
	have actually exited.

	* src/lxc/lxc_controller.c: Rewrite the event loop to use
	  the standard APIs.

	fix crash when starting network
	commit 27908453 introduces a regression, and it will

	qemu: allow getting < max typed parameters
	Since all virTypedParameter APIs allow us to return the number
	of slots we actually populated, we should allow the user to
	call with nparams too small (without overrunning their array)
	or too large (ignoring the tail of the array that we can't fill),
	rather than requiring that they get things exactly right.

	Making this change will make it easier for a future patch to
	introduce VIR_TYPED_PARAM_STRING, with filtering in libvirt.c
	rather than in every single driver, since users already have
	to be prepared for *nparams to be smaller on exit than on entry.

	Add support for probing filesystem with libblkid
	The LXC code for mounting container filesystems from block devices
	tries all filesystems in /etc/filesystems and possibly those in
	/proc/filesystems. The regular mount binary, however, first tries

	Workaround for broken kernel autofs mounts
	The kernel automounter is mostly broken wrt to containers. Most
	notably if you start a new filesystem namespace and then attempt
	to unmount any autofs filesystem, it will typically fail with a
	weird error message like

	  Failed to unmount '/.oldroot/sys/kernel/security':Too many levels of symbolic links

	Attempting to detach the autofs mount using umount2(MNT_DETACH)
	will also fail with the same error. Therefore if we get any error on
	unmount()ing a filesystem from the old root FS when starting a
	container, we must immediately break out and detach the entire
	old root filesystem (ignoring any mounts below it).

	This has the effect of making the old root filesystem inaccessible
	to anything inside the container, but at the cost that the mounts
	live on in the kernel until the container exits. Given that SystemD
	uses autofs by default, we need LXC to be robust this scenario and
	thus this tradeoff is worthwhile.

	* src/lxc/lxc_container.c: Detach root filesystem if any umount
	  operation fails.

	Correctly handle '*' in /etc/filesystems
	The /etc/filesystems file can contain a '*' on the last line to

	a check that this '*' only occurs on the last line. Unfortunately
	when we then start reading /proc/filesystems, we mistakenly think
	we've seen '*' in /proc/filesystems and fail

	esx: Support folders in the path of vpx:// connection URIs
	Allow the datacenter and compute resource parts of the path
	to be prefixed with folders. Therefore, the way the path is
	parsed has changed. Before, it was split in 2 or 3 items and
	the items' meanings were determined by their positions. Now
	the path can have 2 or more items and the the vCenter server
	is asked whether a folder, datacenter of compute resource
	with the specified name exists at the current hierarchy level.

	Before the datacenter and compute resource lookup automatically
	traversed folders during lookup. This is logic got removed
	and folders have to be specified explicitly.

	The proper datacenter path including folders is now used when
	accessing a datastore over HTTPS. This makes virsh dumpxml
	and define work for datacenters in folders.

	ServerClient: Flush cached data
	If daemon is using SASL it reads client data into a cache. This cache is

	qemu: Restore the original states of PCI device when restarting daemon
	To support "managed" mode of host PCI device, we record the original
	states (unbind_from_stub, remove_slot, and reprobe) so that could
	reattach the device to host with original driver. But there is no XML
	for theses attrs, and thus after daemon is restarted, we lose the
	original states. It's easy to reproduce:

	    1) virsh start domain
	    2) virsh attach-device dom hostpci.xml (in 'managed' mode)
	    3) service libvirtd restart
	    4) virsh destroy domain

	    You will see the device won't be bound to the original driver
	if there was one.

	This patch is to solve the problem by introducing internal XML
	(won't be dumped to user, only dumped to status XML). The XML is:
	    <origstates>
	      <unbind/>
	      <remove_slot/>
	      <reprobe/>
	    </origstates>

	Which will be child node of <hostdev><source>...</souce></hostdev>.
	(only for PCI device).

	A new struct "virDomainHostdevOrigStates" is introduced for the XML,
	and the according members are updated when preparing the PCI device.
	And function "qemuUpdateActivePciHostdevs" is modified to honor
	the original states. Use of qemuGetPciHostDeviceList is removed
	in function "qemuUpdateActivePciHostdevs", and the "managed" value of
	the device config is honored by the change. This fixes another problem
	alongside:

	    qemuGetPciHostDeviceList set the device as "managed" force
	    regardless of whether the device is configured as "managed='yes'"
	    or not in XML, which is not right.

	xenapi: Improve error reporting in xenapiOpen once again
	privP->session->error_description is a list and in order to get the
	complete error message all parts of the list should be concatenated.
	xenapiSessionErrorHandler does this when its third parameter is NULL.
	The current code discards all but the first part of the error message
	resulting in a potentially incomplete error message.

	This partly reverts 006be75ee214f9b4, that tried to avoid reporting
	a (null) in the error message. The actual problem is more general in
	returnErrorFromSession that might return NULL if there is no error.

	Make sure that returnErrorFromSession return non-NULL always. Also
	don't skip the last error message part.

	Introduce the virDomainOpenGraphics API
	The virDomainOpenGraphics API allows a libvirt client to pass in
	a file descriptor for an open socket pair, and get it connected
	to the graphics display of the guest. This is limited to working
	with local libvirt hypervisors connected over a UNIX domain
	socket, since it will use UNIX FD passing

	virsh: Fix error message on vol-create-from failure
	If vol-create-from is failed due to 'input volume not found',
	virsh outputs like this:
	  $ sudo virsh vol-create-from testpool test-vol.xml test.img
	  error: failed to get vol 'test.img', specifying --pool might help
	  error: Storage volume not found: no storage vol with matching path
	However, '--pool' is incorrect because it is already specified as
	second argument ('testpool' in this case). It should be "--inputpool".

	The patch fixes this by using pooloptname, which will be "inputpool"
	in this case and "pool" in other cases, as error message.

	Use virXMLSaveFile when writing XML config

	Introduce virXMLSaveFile as a wrapper for virFileRewrite
	Every time we write XML into a file we call virEmitXMLWarning to write a
	warning that the file is automatically generated. virXMLSaveFile
	simplifies this into a single step and makes rewriting existing XML file
	safe by using virFileRewrite internally.

	Introduce virFileRewrite for safe file rewrite
	When saving config files we just overwrite old content of the file. In
	case something fails during that process (e.g. disk gets full) we lose
	both old and new content. This patch makes the process more robust by
	writing the new content into a separate file and only if that succeeds
	the original file is atomically replaced with the new one.

	lxc: avoid null deref on lxcSetupLoopDevices failure
	If the function lxcSetupLoopDevices(def, &nloopDevs, &loopDevs) failed,
	the variable loopDevs will keep a initial NULL value, however, the
	function VIR_FORCE_CLOSE(loopDevs[i]) will directly deref it.

	This patch also fixes returning a bogous number of devices from
	lxcSetupLoopDevices on an error path.

	qemu: simplify use of HAVE_YAJL
	Rather than making all clients of monitor commands that are JSON-only
	check whether yajl support was compiled in, it is simpler to just
	avoid setting the capability bit up front if we can't use the capability.

	Break some long lines, and use more efficient functions when possible,

	util: Add virFileAccessibleAs to private symbols
	Commit 458b7099b2e791b58f1286002974927d3e8bcc80 introduced this
	function. However it was not added into libvirt_private.syms so
	the compilation may not succeed on some hosts.

	startupPolicy: Emit event on disk source dropping
	If a disk source gets dropped because it is not accessible,
	mgmt application might want to be informed about this. Therefore
	we need to emit an event. The event presented in this patch
	is however a bit superset of what written above. The reason is simple:
	an intention to be easily expanded, e.g. on 'user ejected disk
	in guest' events. Therefore, callback gets source string and disk alias
	(which should be unique among a domain) and reason (an integer);

	qemu: implement startupPolicy
	This patch implements on_missing feature in qemu driver.
	Upon qemu startup process an accessibility of CDROMs
	and floppy disks is checked. The source might get dropped
	if unavailable and on_missing is set accordingly.
	No event is emit thought. Look for follow up patch.

	qemu: Move device alias assigning before command line construction
	This patch is rather cosmetic as it only moves device alias
	assignation from command line construction just before that.
	However, it is needed in connotation of previous and next patch.

	util: Create virFileAccessibleAs function
	This function checks if a given path is accessible under
	given uid and gid.

2011-10-25  Michal Privoznik  <mprivozn@redhat.com>

	conf: Introduce optional startupPolicy attribute for cdrom and floppy
	This attribute says what to do with cdrom (or floppy) if
	the source is missing. It accepts:
	- mandatory - fail if missing for any reason (the default)
	- requisite - fail if missing on boot up, drop if missing on
	              migrate/restore/revert
	- optional  - drop if missing at any start attempt.

	However, this patch introduces only XML part of this new
	functionality.

	storage: make previous leak less likely to regress
	Splitting into two functions allows the user to call the right

	storage: plug iscsi memory leak
	Detected by Coverity.  virStoragePoolSourceFree does not free the
	actual passed-in pointer.  A bigger patch would be to rename it
	virStoragePoolSourceClear to match behavior, or even split it into
	two functions depending on needed behavior; but this is the minimal
	fix to the one location out of eight that leaked memory.

	* src/storage/storage_backend_iscsi.c
	(virStorageBackendISCSIFindPoolSources): Free memory.

2011-10-25  Eric Blake  <eblake@redhat.com>

	waitpid: improve safety
	Based on a report by Coverity.  waitpid() can leak resources if it
	fails with EINTR, so it should never be used without checking return
	status.  But we already have a helper function that does that, so
	use it in more places.

	virWaitPid.
	* daemon/libvirtd.c (daemonForkIntoBackground): Likewise.

	qemu: avoid leaking uninit data from hotplug to dumpxml
	Detected by Coverity.  Both text and JSON monitors set only the
	bus and unit fields, which means driveAddr.controller spends
	life as garbage on the stack, and is then memcpy()'d into the
	in-memory representation which the user can see via dumpxml.

	* src/qemu/qemu_hotplug.c (qemuDomainAttachSCSIDisk): Only copy
	defined fields.

2011-10-21  Eric Blake  <eblake@redhat.com>

	snapshot: simplify indentation of cpu features
	Auto-indent makes life a bit easier; this patch also drops unused
	arguments and replaces a misspelled flag name with two entry points
	instead, so that callers don't have to worry about how much spacing

	* src/conf/cpu_conf.h (virCPUFormatFlags): Delete.
	(virCPUDefFormat): Drop unused argument.
	(virCPUDefFormatBuf): Alter signature.

	snapshot: indent domain xml when nesting
	<domainsnapshot> is the first public instance of <domain> being
	used as a sub-element, although we have two other private uses
	(runtime state, and migration cookie).  Although indentation has
	no effect on XML parsing, using it makes the output more consistent.

	This uses virBuffer auto-indentation to obtain the effect, for all
	but the portions of <domain> that are not generated a line at a
	time into the same virBuffer.  Further patches will clean up the
	remaining problems.

	* src/conf/domain_conf.h (virDomainDefFormatInternal): New prototype.

	virbuf: add auto-indentation support

	virbuf: more detailed error reporting
	The next patch wants to add some sanity checking, which would
	be a different error than ENOMEM.  Many existing callers blindly
	report OOM failure if virBuf reports an error, and this will be
	wrong in the (unlikely) case that they actually had a usage error
	instead; but since the most common error really is ENOMEM, I'm
	not going to fix all callers.  Meanwhile, new discriminating
	callers can react differently depending on what failure happened.

	* src/util/buf.c (virBufferSetError): Add parameter.
	(virBufferGrow, virBufferVasprintf, virBufferEscapeString)
	(virBufferEscapeSexpr, virBufferEscapeShell): Adjust callers.

2011-10-21  Eric Blake  <eblake@redhat.com>

	virbuf: improve testsuite reporting
	I had some temporary test failures while working on virbuf
	improvements in later patches, with output that looked like:

	Expected [<]
	Actual [  <]

	which is pretty hard to figure out.  Adding an Offset designation
	made it much easier to find which particular '<' was at the
	wrong indentation, to fix the right part of the code.

	* tests/testutils.c (virtTestDifference): Make it easier to
	diagnose test failures.

2011-10-21  Eric Blake  <eblake@redhat.com>

	virbuf: fix const-correctness
	Although the compiler wasn't complaining (since it was the pointer,
	rather than what was being pointed to, that was actually const), it
	looks quite suspicious to call a function with an argument labeled
	const when the nature of the pointer (virBufferPtr) is hidden behind
	a typedef.  Dropping const makes the function declarations easier
	to read.

	* src/util/buf.h: Drop const from all functions that modify buffer
	argument.
	* src/util/buf.c (virBufferSetError, virBufferAdd)
	(virBufferContentAndReset, virBufferFreeAndReset)
	(virBufferAsprintf, virBufferVasprintf, virBufferEscapeString)

	In a recent expansion of the documentation on network forward modes, I

	There is a little difference between the output of domxml-to-native and the actual commandline.

	qemu: Fix name-space handling
	The XML parser for the qemu specific extensions expects the qemu name-space
	to be bound to the 'qemu' prefix. This is too strict, since the name of the
	name-space-prefix is only meant as an internal lookup key. Only the associated
	URI is relevant.
	<domain>...
	  <qemu:commandline xmlns:qemu="http://libvirt.org/schemas/domain/qemu/1.0">
	  ...</qemu:commandline>
	</domain>

	<domain xmlns:ns0="http://libvirt.org/schemas/domain/qemu/1.0">...

	</domain>

	Remove the test for checking the name-space binding on the top-level <domain>
	element. Registering the name-space with XPath is enough.

	qemu: Honor the orginal PCI dev properties when reattaching
	BZ# https://bugzilla.redhat.com/show_bug.cgi?id=736214

	The problem is caused by the original info of domain's PCI dev is
	maintained by qemu_driver->activePciHostdevs list, (E.g. dev->reprobe,
	which stands for whether need to reprobe driver for the dev when do
	reattachment). The fields (dev->reprobe, dev->unbind_from_stub, and
	dev->remove_slot) are initialized properly when preparing the PCI
	device for managed attachment. However, when do reattachment, it
	construct a complete new "pciDevice" without honoring the original
	dev info, and thus the dev won't get the original driver or can get
	other problem.

	This patch is to fix the problem by get the devs from list
	driver->activePciHostdevs.

	Tested with following 3 scenarios:
	  * the PCI was bound to some driver not pci-stub before attaching

	    result: the device will be bound to the original driver

	  * the PCI was bound to pci-stub before attaching

	    result: no driver reprobing, and still bound to pci-stub

	  * The PCI was not bound to any driver

	    result: no driver reprobing, and still not bound to any driver.

	docs: fix network XML documentation
	A few people have attempted to use the new forwarding modes with older
	versions of libvirt. The docs where the modes are described have
	always stated the minimum required libvirt version, but the examples
	at the end didn't, which I believe is what has caused the confusion.

	Similarly, the section on portgroups now has a version tag added at
	the beginning.

	I also noticed that there was no example of defining a <dns> hostname,
	so I added one, as well as making the domain name example more
	recognizable (by adding ".com" to the domain).

	qemu: Do not reattach PCI device used by other domain when shutdown
	When failing on starting a domain, it tries to reattach all the PCI
	devices defined in the domain conf, regardless of whether the devices
	are still used by other domain. This will cause the devices to be deleted
	from the list qemu_driver->activePciHostdevs, thus the devices will be
	thought as usable even if it's not true. And following commands
	nodedev-{reattach,reset} will be successful.

	How to reproduce:
	  1) Define two domains with same PCI device defined in the confs.
	  2) # virsh start domain1
	  3) # virsh start domain2
	  4) # virsh nodedev-reattach $pci_device

	You will see the device will be reattached to host successfully.
	As pciDeviceReattach just check if the device is still used by
	other domain via checking if the device is in list driver->activePciHostdevs,
	however, the device is deleted from the list by step 2).

	This patch is to prohibit the bug by:
	  1) Prohibit a domain starting or device attachment right at
	     preparation period (qemuPrepareHostdevPCIDevices) if the
	     device is in list driver->activePciHostdevs, which means
	     it's used by other domain.

	  2) Introduces a new field for struct _pciDevice, (const char *used_by),
	     it will be set as the domain name at preparation period,
	     (qemuPrepareHostdevPCIDevices). Thus we can prohibit deleting
	     the device from driver->activePciHostdevs if it's still used by
	     other domain when stopping the domain process.

	* src/pci.h (define two internal functions, pciDeviceSetUsedBy and
	    pciDevceGetUsedBy)
	* src/pci.c (new field "const char *used_by" for struct _pciDevice,
	    implementations for the two new functions)

	    device from activePciHostdevs list if it's still used by other domain)

	As this is needed. Although some functions check for domain
	being active before obtaining job, we need to check it after,
	because obtaining job unlocks domain object, during which
	a state of domain can be changed.

	events: Propose a separate lock for event queue
	Currently, push & pop from event queue (both server & client side)
	rely on lock from higher levels, e.g. on driver lock (qemu),
	private_data (remote), ...; This alone is not sufficient as not
	every function that interacts with this queue can/does lock,
	esp. in client where we have a different approach, "passing
	the buck".

	Therefore we need a separate lock just to protect event queue.

	qemu: Implement VIR_DUMP_RESET
	This patch extends qemudDomainCoreDump so it supports new VIR_DUMP_RESET
	flag. If this flag is set, domain is reset on successful dump. However,
	this is needed to be done after we start CPUs.

	virDomainCoreDump: Introduce VIR_DUMP_RESET flag
	This flag is intended to allow user to do so called system reset
	after dump, instead of sending ACPI reboot event.

	example: Support debug output and loop switch
	Add support for enabling debug output via command line option.
	Allow to toggle the loop implementation between pure-Python and
	native-C.

	example: Redirect --help output to stdout/stderr
	When --help is requested, print usage() to stdout.
	When an illegal option is passed, print usage to stderr.

	example: Fix argument handling
	sys.argv contains the original command line arguments, while args only
	contains the arguments not handled by getopt(). Currently this is no
	problem since --help is the only command line option passable, which
	terminates the process, so the code is never reached. Any option added
	in the future will reveal the bug.

	xen: Return tap2 for tap2 disks
	For some versions of Xen the difference between "tap" and "tap2" is
	important. When converting back from xen-sxpr to libvirt-xml, that
	information is lost, which breaks re-defining the domain using that
	data.

	Explicitly return "tap2" for disks defined as "device/tap2".

2011-10-13  Philipp Hahn  <hahn@univention.de>

	xen: fix PyGrub boot device order
	When PyGrub is used as the bootloader in Xen, it gets passed the first
	bootable disk. Xend supports a "bootable"-flag for this, which isn't
	explicitly supported by libvirt.
	When converting libvirt-xml to xen-sxpr the "bootable"-flag gets
	implicitly set by xen.xend.XenConfig.device_add() for the first disk
	(marked as "Compat hack -- mark first disk bootable").
	When converting back xen-sxpr to libvirt-xml, the disks are returned in
	the internal order used by Xend ignoring the "bootable"-flag, which
	loses the original order. When the domain is then re-defined, the order
	of disks is changed, which breaks PyGrub, since a different disk gets
	passed.

	When converting xen-sxpr to libvirt-xml, use the "bootable"-flag to
	determine the first disk.

	This isn't perfect, since several disks can be marked as bootable using
	the Xend-API, but that is not supported by libvirt. In all known cases
	relevant to libvirt exactly one disk is marked as bootable.

	Introduce <driver> under <filesystem> to support open-by-handle
	VirtFS allows the user to choose between path/handle based fs driver.

	daemon: Always advertise libvirtd service
	This is a regression introduced by new RPC codes, previously
	we advertise the service via ssh even if the daemon doesn't
	listen on TLS port (TCP is not choosed). Now the service is
	only advertised when it listens on TLS or TCP port. This breaks
	upper layer apps which intends to discover the service, such
	as virt-manager.

	snapshot: framework for more efficient relation traversal
	No one was using virDomainSnapshotHasChildren, but that was an
	O(n) function.  Exposing and tracking a bit more metadata for each
	snapshot will allow the same query to be made with an O(1) query
	of the member field.  For single snapshot operations (create,
	delete), callers can be trusted to maintain the metadata themselves,
	but for reloading, we can't compute parents as we go since there
	is no guarantee that parents were parsed before children, so we also
	provide a function to refresh the relationships, and which can
	be used to detect if the user has ignored our warnings and been
	directly modifying files in /var/lib/libvirt/qemu/snapshot.  This
	patch only adds metadata; later patches will actually use it.

	This layout intentionally hardcodes the size of each snapshot struct,
	by tracking sibling pointers, rather than having to deal with the
	headache of yet more memory management by directly sticking a
	dynamically sized child[] on each parent.

	* src/conf/domain_conf.h (_virDomainSnapshotObj)
	(_virDomainSnapshotObjList): Add members.

	snapshot: virsh shorthand for operating on current snap
	Rather than having to do:

	$ virsh snapshot-revert dom $(virsh snapshot-current dom --name)

	I thought it would be nice to do:

	$ virsh snapshot-revert dom --current

	I didn't add 'virsh snapshot-dumpxml --current' since we already have
	'virsh snapshot-current' for the same task.  snapshot-list accepted
	a name but did not require it, and that remains the case, with
	--current serving in place of that name.  For all other commands,
	name used to be required, and can now be replaced by --current;
	I intentionally made it so that omitting both --current and a name
	is an error (having the absence of a name imply --current seems
	just a bit too magic, so --current must be explicit).  I also had
	to keep snapshot-edit backwards-compatible, as the only command
	that already had a --current argument alongside a name, which still
	works to both edit a named snapshot and make it current.

	* tools/virsh.c (vshLookupSnapshot): New helper function.
	(cmdSnapshotEdit, cmdSnapshotList, cmdSnapshotParent)
	(cmdSnapshotDelete, cmdDomainSnapshotRevert): Use it, adding an

	build: fix 'make check' linkage with dtrace
	Building on Linux with dtrace enabled was failing 'make check':

	  CCLD   nodeinfotest
	../src/.libs/libvirt_test.a(libvirt_net_rpc_client_la-virnetclient.o): In function `virNetClientNew':
	/home/remote/eblake/libvirt/src/rpc/virnetclient.c:162: undefined reference to `libvirt_rpc_client_new_semaphore'

	On looking further, I see some earlier warnings emitted from libtool:

	*** Warning: Linking the shared library libvirt.la against the non-libtool
	*** objects  probes.o is not portable!

	Since src/probes.o is only built on Linux, and even then, only when
	dtrace is enabled, this failure does not affect other platforms, and
	despite libtool warning that it is not generally portable, it is not
	a problem for our use-case in libvirt.la.  But it turns out that while
	libtool is willing to jam raw .o files into an installed shared
	library (libvirt.la becomes libvirt.so), it is NOT willing to jam
	the same .o file into the convenience library libvirt_test.la.
	Perhaps this is a bug in libtool, but even if we get libtool fixed,
	libvirt must continue to build on platforms with older libtool.  So,
	the fix is the same as we are already using for the libvirt_lxc
	executable - don't rely on the .o file being in the convenience
	library, but instead use LDADD to pull it in directly.

	Update examples for probing with systemtap
	This removes the old example for legacy probes and adds two

	useful in seeing what RPC calls are being made, and also debugging
	problems in the RPC protocol code

	The events.stp script will print out lots of info about the poll
	event loop, which is useful for debugging event handling problems

	Rewrite all the DTrace/SystemTAP probing
	The libvirtd daemon had a few crude system tap probes. Some of
	these were broken during the RPC rewrite. The new modular RPC
	code is structured in a way that allows much more effective
	tracing. Instead of trying to hook up the original probes,
	define a new set of probes for the RPC and event code.

	The master probes file is now src/probes.d.  This contains
	probes for virNetServerClientPtr, virNetClientPtr, virSocketPtr
	virNetTLSContextPtr and virNetTLSSessionPtr modules. Also add
	probes for the poll event loop.

	The src/dtrace2systemtap.pl script can convert the probes.d
	file into a libvirt_probes.stp file to make use from systemtap
	much simpler.

	The src/rpc/gensystemtap.pl script can generate a set of
	systemtap functions for translating RPC enum values into
	printable strings. This works for all RPC header enums (program,
	type, status, procedure) and also the authentication enum

	The PROBE macro will automatically generate a VIR_DEBUG
	statement, so any place with a PROBE can remove any existing
	manual DEBUG statements.

	The kernel element is there but unset. This leads to an empty <kernel/>

	snapshot: avoid accidental renames with snapshot-edit
	I was a bit surprised that 'virsh snapshot-edit dom name' silently
	allowed me to clone things, while still telling me the old name,
	especially since other commands like 'virsh edit dom' reject rename
	attempts (*).  This fixes things to be more explicit (**).

	(*) Technically, 'virsh edit dom' relies on virDomainDefineXML
	behavior, which rejects attempts to mix a new name with existing
	uuid or new uuid with existing name, but you can create a new
	domain by changing both uuid and name.  On the other hand, while
	snapshot-edit --clone is a true clone, creating a new domain
	would also have to decide whether to clone snapshot metadata,
	managed save, and any other secondary data related to the domain.
	Domain renames are not trivial either.

	(**) Renaming or creating a clone is still a risky proposition -
	for offline snapshots and system checkpoints, if the new name
	does not match an actual name recorded in the qcow2 internal
	snapshots, then you cannot revert to the new checkpoint.  But it
	is assumed that anyone using the new virsh flags knows what they
	are doing, and can deal with the fallout caused by a rename/clone;
	that is, we can't completely prevent a user from shooting
	themselves in the foot, so much as we are making the default
	action less risky.

	* tools/virsh.c (cmdSnapshotEdit): Add --rename, --clone.
	* tools/virsh.pod (snapshot-edit): Document them.

	storage: Do not use comma as seperator for lvs output
	* src/storage/storage_backend_logical.c:

	If a logical vol is created as striped. (e.g. --stripes 3),
	the "device" field of lvs output will have multiple fileds which are
	seperated by comma. Thus the RE we write in the codes will not
	work well anymore. E.g. (lvs output for a stripped vol, uses "#" as
	seperator here):

	test_stripes##fSLSZH-zAS2-yAIb-n4mV-Al9u-HA3V-oo9K1B#\
	/dev/sdc1(10240),/dev/sdd1(0)#42949672960#4194304

	The RE we use:

	    const char *regexes[] = {
	        "^\\s*(\\S+),(\\S*),(\\S+),(\\S+)\\((\\S+)\\),(\\S+),([0-9]+),?\\s*$"
	    };

	Also the RE doesn't match the "devices" field of striped vol properly,
	it contains multiple "device path" and "offset".

	This patch mainly does:
	    1) Change the seperator into "#"
	    2) Change the RE for "devices" field from "(\\S+)\\((\\S+)\\)"
	       into "(\\S+)".
	    3) Add two new options for lvs command, (segtype, stripes)
	    4) Extend the RE to match the value for the two new fields.
	    5) Parse the "devices" field seperately in virStorageBackendLogicalMakeVol,
	       multiple "extents" info are generated if the vol is striped. The
	       number of "extents" is equal to the stripes number of the striped vol.

	A incidental fix: (virStorageBackendLogicalMakeVol)
	    Free "vol" if it's new created and there is error.

	Demo on striped vol with the patch applied:

	% virsh vol-dumpxml /dev/test_vg/vol_striped2

2011-10-07  Laine Stump  <laine@laine.org>

	qemu: add separate rerror_policy for disk errors
	Previously libvirt's disk device XML only had a single attribute,
	error_policy, to control both read and write error policy, but qemu
	has separate options for controlling read and write. In one case
	(enospc) a policy is allowed for write errors but not read errors.

	This patch adds a separate attribute that sets only the read error
	policy. If just error_policy is set, it will apply to both read and
	write error policy (previous behavior), but if the new rerror_policy
	attribute is set, it will override error_policy for read errors only.
	Possible values for rerror_policy are "stop", "report", and "ignore"
	("report" is the qemu-controlled default for rerror_policy when
	error_policy isn't specified).

	For consistency, the value "report" has been added to the possible
	values for error_policy as well.

2011-10-07  Laine Stump  <laine@laine.org>

	qemu: leave rerror policy at default when enospace is requested
	commit 12062ab set rerror=ignore when error_policy="enospace" was
	selected (since the rerror option in qemu doesn't accept "enospc", as
	the werror option does).

	After that patch was already pushed, Paolo Bonzini noticed it and
	commented that leaving rerror at the default ("report") would be a
	better choice. This patch corrects the problem - if error_policy =
	"enospace" is given, rerror is left off the qemu commandline,
	effectively setting it to "report". For other values, rerror is still
	set to match werror.

	Additionally, the parsing of error_policy was changed to no longer
	erroneously allow "default" as a choice - as with most other
	attributes, if you want the default setting, just don't specify an
	error_policy.

	Finally, two ommissions in the first patch were corrected - a
	long-dormant qemuxml2argv test for enospace was enabled, and fixed to
	pass, and the argv2xml parser in qemu_command.c was updated to
	recognize the different spelling on the qemu commandline.

	init: raise default system aio limits
	https://bugzilla.redhat.com/show_bug.cgi?id=740899 documents that
	if qemu uses aio=native for its disks, then it consumes 128 aio
	requests per disk.  On a host with multiple guests, this can quickly
	run out of kernel aio requests with the default aio-max-nr of
	65536.  Kernel developers have confirmed that there is no up-front
	cost to raising this limit (a larger limit merely implies that more
	aio requests can be issued in parallel, which in turn will result
	in more kernel memory allocation, only if the system really does use
	that many requests).  Since the system default limit prevents 256
	disks, which is well within libvirt's current scalability, this
	patch installs a file to raise the limit and document it in case a
	system administrator has further cause to tune the limit.  The
	install only works on platforms new enough to source /etc/sysctl.d/*
	alongside /etc/sysctl.conf (F14 and RHEL 6).

	Also create a new error code, so users can distinguish when forcing
	would make a difference, rather than having to blindly request force.

	Commit 9f5e53e introduced the ability to filter snapshots to

	The VBox implementation prohibits deletion of a snapshot with

	qemu: correct misspelled 'enospc' option, and only use for werror
	This resolves:

	     https://bugzilla.redhat.com/show_bug.cgi?id=730909

	When support for setting the qemu disk error policy to "enospc" was
	added, it was inadvertently spelled "enospace". This patch corrects
	that on the qemu commandline (while retaining the "enospace" spelling
	for libvirt's XML).

	Also, while examining the qemu source, I found that "enospc" is not
	allowed for the read error policy, only for write error policy (makes
	sense). Since libvirt currently only has a single error policy
	setting, when "enospace" is selected, the read error policy is set to
	"ignore".

	snapshot: better virsh handling of missing current, parent
	Previously, virsh 'snapshot-parent' and 'snapshot-current' were
	completely silent in the case where the code conclusively proved
	there was no parent or current snapshot, but differed in exit
	status; this silence caused some confusion on whether the commands
	worked.  Furthermore, commit d1be48f introduced a regression where
	snapshot-parent would leak output about an unknown function, but
	only on the first attempt, when talking to an older server that
	lacks virDomainSnapshotGetParent.  This changes things to consistenly
	report an error message and exit with status 1 when no snapshot
	exists, and to avoid leaking unknown function warnings when using
	fallbacks.

	* tools/virsh.c (vshGetSnapshotParent): Alter signature, to
	distinguish between real error and missing parent.  Don't pollute

	Allow passing of command line args to LXC container
	When booting a virtual machine with a kernel/initrd it is possible
	to pass command line arguments using the <cmdline>...args...</cmdline>
	element in the guest XML. These appear to the kernel / init process
	in /proc/cmdline.

	When booting a container we do not have a custom /proc/cmdline,
	but we can easily set an environment variable for it. Ideally
	we could pass individual arguments to the init process as a
	regular set of 'char *argv[]' parameters, but that would involve

	network: fill in bandwidth from portgroup for all forward modes
	This patch is a fix for:

	  https://bugzilla.redhat.com/show_bug.cgi?id=743176

	which was discovered by Dan Berrange while making bandwidth
	configuration work for LXC guests.

	Background: Although virtportprofile data from a network portgroup is
	only applicable for direct mode interfaces, the code that copies
	bandwidth data from the portgroup was also only being executed in the
	case of direct mode interfaces. The result was that interfaces using
	traditional virtual networks (forward mode='nat|route|none'), and
	those using a host bridge for forwarding, would not pick up bandwidth
	data from a portgroup defined in the network.

	This patch moves that code outside the conditional, so that bandwidth
	information is *alway* copied from the appropriate portgroup (unless
	the <interface> definition itself already has bandwidth information,
	which would take precedence over what's in the portgroup anyway).

	qemu: make PCI multifunction support more manual
	When support for was added for PCI multifunction cards (in commit
	9f8baf, first included in libvirt 0.9.3), it was done by always
	turning on the multifunction bit for all PCI devices. Since that time
	it has been realized that this is not an ideal solution, and that the
	multifunction bit must be selectively turned on. For example, see

	  https://bugzilla.redhat.com/show_bug.cgi?id=728174

	and the discussion before and after

	  https://www.redhat.com/archives/libvir-list/2011-September/msg01036.html

	This patch modifies multifunction support so that the multifunction=on
	option is only added to the qemu commandline for a device if its PCI
	<address> definition has the attribute "multifunction='on'", e.g.:

	  <address type='pci' domain='0x0000' bus='0x00'
	           slot='0x04' function='0x0' multifunction='on'/>

	In practice, the multifunction bit should only be turned on if
	function='0' AND other functions will be used in the same slot - it
	usually isn't needed for functions 1-7 (although there are apparently
	some exceptions, e.g. the Intel X53 according to the QEMU source
	code), and should never be set if only function 0 will be used in the
	slot. The test cases have been changed accordingly to illustrate.

	With this patch in place, if a user attempts to assign multiple
	functions in a slot without setting the multifunction bit for function
	0, libvirt will issue an error when the domain is defined, and the
	define operation will fail. In the future, we may decide to detect
	this situation and automatically add multifunction=on to avoid the
	error; even then it will still be useful to have a manual method of
	turning on multifunction since, as stated above, there are some
	devices that excpect it to be turned on for all functions in a slot.

	A side effect of this patch is that attempts to use the same PCI
	address for two different devices will now log an error (previously
	this would cause the domain define operation to fail, but there would
	be no log message generated). Because the function doing this log was
	almost completely rewritten, I didn't think it worthwhile to make a
	separate patch for that fix (the entire patch would immediately be
	obsoleted).

	lvm storage backend: handle command_names=1 in lvm.conf
	If the regexes supported (?:pvs)?, then we could handle this by
	optionally matching but not returning the initial command name.  But it
	doesn't.  So add a new char* argument to
	virStorageBackendRunProgRegex().  If that argument is NULL then we act
	as usual.  Otherwise, if the string at that argument is found at the
	start of a returned line, we drop that before running the regex.

	With this patch, virt-manager shows me lvs with command_names 1 or 0.

	The definitions of PVS_BASE etc may want to be moved into the configure
	scripts (though given how PVS is found, IIUC that could only happen if
	pvs was a link to pvs_real), but in any case no sense dealing with that
	until we're sure this is an ok way to handle it.

	security: properly chown/label bidirectional and unidirectional fifos
	This patch fixes the regression with using named pipes for qemu serial
	devices noted in:

	  https://bugzilla.redhat.com/show_bug.cgi?id=740478

	The problem was that, while new code in libvirt looks for a single
	bidirectional fifo of the name given in the config, then relabels that
	and continues without looking for / relabelling the two unidirectional
	fifos named ${name}.in and ${name}.out, qemu looks in the opposite
	order. So if the user had naively created all three fifos, libvirt
	would relabel the bidirectional fifo to allow qemu access, but qemu
	would attempt to use the two unidirectional fifos and fail (because it
	didn't have proper permissions/rights).

	This patch changes the order that libvirt looks for the fifos to match
	what qemu does - first it looks for the dual fifos, then it looks for
	the single bidirectional fifo. If it finds the dual unidirectional
	fifos first, it labels/chowns them and ignores any possible
	bidirectional fifo.

	(Note commit d37c6a3a (which first appeared in libvirt-0.9.2) added
	the code that checked for a bidirectional fifo. Prior to that commit,
	bidirectional fifos for serial devices didn't work because libvirt
	always required the ${name}.(in|out) fifos to exist, and qemu would
	always prefer those.

	qemu: Preserve fakeReboot flag in domain status
	Thus, when libvirtd is restarted, it will know if a domain is supposed

	qemu: Finish domain shutdown on reconnect
	If a domain started with -no-shutdown shuts down while libvirtd is not
	running, it will be seen as paused when libvirtd reconnects to it. Use

	and finish the process just as if a SHUTDOWN event is delivered from
	qemu.

	qemu: Check domain status details when reconnecting monitor
	Current qemu is able to give us detailed domain status (not just if it

	qemu: add ability to set PCI device "rombar" on or off
	This patch was made in response to:

	  https://bugzilla.redhat.com/show_bug.cgi?id=738095

	In short, qemu's default for the rombar setting (which makes the
	firmware ROM of a PCI device visible/not on the guest) was previously
	0 (not visible), but they recently changed the default to 1
	(visible). Unfortunately, there are some PCI devices that fail in the
	guest when rombar is 1, so the setting must be exposed in libvirt to
	prevent a regression in behavior (it will still require explicitly
	setting <rom bar='off'/> in the guest XML).

	rombar is forced on/off by adding:

	  <rom bar='on|off'/>

	inside a <hostdev> element that defines a PCI device. It is currently
	ignored for all other types of devices.

	At the moment there is no clean method to determine whether or not the
	rombar option is supported by QEMU - this patch uses the advice of a
	QEMU developer to assume support for qemu-0.12+. There is currently a
	patch in the works to put this information in the output of "qemu-kvm
	-device pci-assign,?", but of course if we switch to keying off that,
	we would lose support for setting rombar on all the versions of qemu
	between 0.12 and whatever version gets that patch.

	qemu: Relax -no-shutdown check to [0.14.0, 0.15.50)
	SIGTERM handling for -no-shutdown is already fixed in qemu git and
	libvirt can safely use it. The downside is that 0.15.50 version of qemu
	can be any qemu compiled from git, even that without the fix for
	SIGTERM. However, I think this patch is worth it since excluding 0.15.50
	from the check makes testing current qemu with libvirt much easier and
	someone running qemu from git should be able to rebuild fixed qemu from
	git if they hit the problem with a hang on shutdown.

	virsh: fix regression in argv parsing
	Prior to commit 85d2810, we had an issue where:

	snapshot-create-as dom name --diskspec spec --diskspec spec

	failed to parse the second spec, because the first spec had marked
	that option as no longer requiring an argument.

	In commit 85d2810, I fixed it by making argv options no longer mark
	the option as seen.  But this in turn breaks mandatory argv options,
	which now complain that the argv option is missing.

	This patch reverts that part of 85d2810, and instead replaces it with
	fixes to no longer clear opts_need_arg of an argv argument.

	storage: Wait udev events are handled before removing lvm vol
	Related #BZ: https://bugzilla.redhat.com/show_bug.cgi?id=702260.

	There are two problems described in the BZ:
	1) "Can't remove open logical volume".
	2) "Unable to deactivate logical volume "foo""

	This patch just intends to fix 2), as 1) is expected if the vol
	is still used by something, and you never known if "lvchange -an"
	will fail or not either (sometime, it will succeed, sometimes not).
	We'd better not look for trouble, :-)

	For 2), that's caused by race between lvremove and udev event handling,
	the only workable way now is to wait the events handling are finished,
	though it might introduce latencies, as "udevadmin settle" exits
	after *all* events are handled, it's the only way we can fix
	the racing in libvirt layer.

	See https://bugzilla.redhat.com/show_bug.cgi?id=570359 for more

	qemu: Avoid loop of fake reboots
	Once virDomainReboot is called for a domain, guest OS initiated shutdown
	would always result in reboot instead of shutdown. Only
	virDomainShutdown would actually shutd such domain down. That's because
	we forgot to reset fakeReboot flag once we asked the domain to reboot.

	qemu: Fix shutdown regression with buggy qemu
	The commit that prevents disk corruption on domain shutdown
	(96fc4784177ecb70357518fa863442455e45ad0e) causes regression with QEMU
	0.14.* and 0.15.* because of a regression bug in QEMU that was fixed
	only recently in QEMU git. The affected versions of QEMU do not quit on
	SIGTERM if started with -no-shutdown, which we use to implement fake
	reboot. Since -no-shutdown tells QEMU not to quit automatically on guest
	shutdown, domains started using the affected QEMU cannot be shutdown
	properly and stay in a paused state.

	This patch disables fake reboot feature on such QEMU by not using
	-no-shutdown, which makes shutdown work as expected. However,
	virDomainReboot will not work in this case and it will report "Requested
	operation is not valid: Reboot is not supported with this QEMU binary".

	Update to require sanlock 1.8 for license compliance
	Inexplicably the sanlock code all got placed under the GPLv2-only,
	so libvirt's use of sanlock introduces a license incompatibility.
	The sanlock developers have now rearranged the code such that there
	is a 'sanlock_client.so' which is LGPLv2+ while their daemon remains
	GPLv2-only. To use the new client library we need to call the new
	sanlock_init and sanlock_align APIs instead of sanlock_direct_init
	and sanlock_direct_align. These APIs calls are now routed via the
	sanlock daemon, instead of doing direct I/O calls to disk.

	For all this we require sanlock >= 1.8

	* configure.ac: Check for sanlock_client.so instead of sanlock.so
	  and fix various comments
	* libvirt.spec.in: Mandate sanlock >= 1.8

	conf: Assign newDef of active domain as persistent conf if it is NULL
	Libvirt loads the domain conf from status XML if it's running when
	starting up. The problem is there is no record of the original conf.
	(dom->newDef is NULL here).

	So libvirt won't be able to restore the domain conf to original one
	when destroying/shutdown. E.g.

	1) attach a device without "--persistent"
	2) restart libvirtd
	3) destroy domain
	4) start domain

	One will see the the disk still exists.

	snapshot: allow disk snapshots of qcow2 disks
	For all types of disks other than qcow2, we were requesting that
	SELinux labeling visit the new file as if it were qcow2, which
	means labeling would try to find the backing files of an empty file.
	And for a pre-existing qcow2 disk, we were passing NULL, which meant
	that labelling tried to probe the file type (and if probing is
	disabled, per the default qemu.conf, this made snapshots fail).
	What we really want is to make SELinux labeling visit the new

	made the snapshot.

	Prevent crash from dlclose() of libvirt.so
	When libvirt calls virInitialize it creates a thread local
	for the virErrorPtr storage, and registers a callback to
	cleanup memory when a thread exits. When libvirt is dlclose()d
	or otherwise made non-resident, the callback function is
	removed from memory, but the thread local may still exist
	and if a thread later exists, it will invoke the callback
	and SEGV. There may also be other thread locals with callbacks
	pointing to libvirt code, so it is in general never safe to
	unload libvirt.so from memory once initialized.

	To allow dlclose() to succeed, but keep libvirt.so resident
	in memory, link with '-z nodelete'. This issue was first
	found with the libvirt CIM provider, but can potentially
	hit many of the dynamic language bindings which all ultimately
	involve dlopen() in some way, either on libvirt.so itself,
	or on the glue code for the binding which in turns links
	to libvirt

	qemu: Introduce shutdown reason for paused state
	Qemu sends STOP event as part of the shutdown process. Detect such STOP
	event and consider shutdown to be reason of emitting such event. That's
	the best we can do until qemu provides us the reason directly in STOP
	event. This allows us to report shutdown reason for paused state so that
	apps can detect domains that failed to finish the shutdown process
	(e.g., because qemu is buggy and doesn't exit on SIGTERM or it is
	blocked in flushing disk buffers).

2011-09-16  Jiri Denemark  <jdenemar@redhat.com>

	qemu: Prevent disk corruption on domain shutdown
	Ever since we introduced fake reboot, we call qemuProcessKill as a
	reaction to SHUTDOWN event. Unfortunately, qemu doesn't guarantee it
	flushed all internal buffers before sending SHUTDOWN, in which case
	killing the process forcibly may result in (virtual) disk corruption.

	By sending just SIGTERM without SIGKILL we give qemu time to to flush
	all buffers and exit. Once qemu exits, we will see an EOF on monitor
	connection and tear down the domain. In case qemu ignores SIGTERM or
	just hangs there, the process stays running but that's not any different
	from a possible hang anytime during the shutdown process so I think it's
	just fine.

	Also qemu (since 0.14 until it's fixed) has a bug in SIGTERM processing
	which causes it not to exit but instead send new SHUTDOWN event and keep
	waiting. I think the best we can do is to ignore duplicate SHUTDOWN
	events to avoid a SHUTDOWN-SIGTERM loop and leave the domain in paused
	state.

2011-09-16  Jiri Denemark  <jdenemar@redhat.com>

	qemu: Properly detect crash of a rebooted domain
	When a domain is rebooted using libvirt API, we use fake reboot
	consisting of shutting down and resetting the domain. Thus we see a
	SHUTDOWN event and set gotShutdown flag. But we never reset it back and
	if the domain crashes after it was rebooted this way, we consider it was
	a normal shutdown and not a crash.

	qemu: Fix shutoff reason when domain crashes
	Commit 4454a9efc728b91e791b1f14c26ea23a19d57f48 changed shutoff reason
	from VIR_DOMAIN_SHUTOFF_CRASHED to VIR_DOMAIN_SHUTOFF_FAILED in case we
	see an unexpected EOF on monitor connection. But FAILED reason is
	dedicated for domains that fail to start. CRASHED reason is the right
	one to use in this situation.

	snapshot: tweak snapshot-create-as diskspec docs
	With this patch, it is hopefully a bit more obvious that for
	snapshot-create-as, a literal '--diskspec' is mandatory if name
	or description was omitted, but optional if all earlier options
	were provided.

	These all denote two diskspecs and a description:
	virsh snapshot-create-as dom name desc vda vdb
	virsh snapshot-create-as dom name desc --diskspec vda --diskspec vdb
	virsh snapshot-create-as dom name desc --diskspec vda vdb
	virsh snapshot-create-as dom name desc vda --diskspec vdb
	virsh snapshot-create-as dom --diskspec vda --diskspec vdb name desc

	This gives two diskspecs but no description:
	virsh snapshot-create-as dom name --diskspec vda --diskspec vdb

	And this treats 'vda' as the description, with only one diskspec:
	virsh snapshot-create-as dom name vda vdb

	The help output now shows:
	    snapshot-create-as <domain> [<name>] [<description>] [--print-xml] [--no-metadata] [--halt] [--disk-only] [[--diskspec] <string>]...

	I also checked the help output for echo and send-key, which are two
	other variants of argv commands.

	Use max bandwidth from qemuDomainObjPrivate struct when migrating

	The qemu migration speed default is 32MiB/s as defined in migration.c

	/* Migration speed throttling */
	static int64_t max_throttle = (32 << 20);

	There's no need to throttle migration when targeting a file, so set migration
	speed to unlimited prior to migration, and restore to libvirt default value
	after migration.

	Default units is MB for migrate_set_speed monitor command, so
	(INT64_MAX / (1024 * 1024)) is used for unlimited migration speed.

	snapshot: ABI stability must include memory sizing
	Commit 973fcd8f introduced the ability for qemu to reject snapshot
	reversion on an ABI incompatibility; but the very example that was
	first proposed on-list[1] as a demonstration of an ABI incompatibility,
	namely that of changing the max memory allocation, was not being
	checked for, resulting in a cryptic failure when running with larger
	max mem than what the snapshot was created with:
	error: operation failed: Error -22 while loading VM state

	This commit merely protects the three variables within mem that are
	referenced by qemu_command.c, rather than all 7 (the other 4 variables
	affect cgroup handling, but as far as I can tell, have no visible effect
	to the qemu guest).  This also affects migration and save file handling,
	which are other places where we perform ABI compatibility checks.

	Fix URL-escaping for domainDefine
	'+' in strings get translated to ' ' when editing domains.
	While xenDaemonDomainCreateXML() did URL-escape the sexpr,
	xenDaemonDomainDefineXML() did not.

	Remove the explicit urlencode() in xenDaemonDomainCreateXML() and add
	the direct encoding calls to xend_op_ext() because it calls xend_post()
	which uses "Content-Type: application/x-www-form-urlencoded". According
	to <http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1> this
	requires all parameters to be url-encoded as specified in rfc1738.

	Notice: virBufferAsprintf(..., "%s=%s", ...) is again replaced by three
	calls to virBufferURIEncodeString() and virBufferAddChar() because '='
	is a "reserved" character, which would get escaped by
	virBufferURIEncodeString(), which - by the way - escapes anything not
	c_isalnum().

	xml: Change virtual file names of xml documents parsed in memory
	While parsing XML strings from memory, the previous convention in
	libvirt was to set the virtual file name to "domain.xml" or something
	similar. This could potentialy trick the user into looking for a file
	named domain.xml on the disk in an attempt to fix the error.

	This patch changes these filenames to something that can't be as easily
	confused for a valid filename.

	Don't treat pci_system_init failure as fatal if no PCI bus is present

	which looks for /sys/bus/pci. If it does not find /sys/bus/pci (which it
	won't in a Xen PV domU) it returns unsuccesfully (ENOENT), which libvirt

	link-state: qemu: Add monitor handling for link state modification
	This patch adds handlers for modification of guest's interface
	link state. Both HMP and QMP commands are supported, but as the
	link state functionality is from the beginning supported in QMP
	the HMP code will probably never be used.

	XML: Improve XML parsing error messages
	This patch modifies error handling function for the XML parser provided
	by libxml2.

	Originaly only a line number and error message were logged. With this
	new error handler function, the user is provided with a more complex
	description of the parsing error.

	Context of the error is printed in libXML2 style and filename of the
	file, that caused the error is printed. Example of an parse error:

	13:41:36.262: 16032: error : catchXMLError:706 :
	/etc/libvirt/qemu/rh_bad.xml:58: Opening and ending tag mismatch: name
	line 2 and domain
	</domain>
	---------^

	Context of the error gives the user hints that may help to quickly
	locate a corrupt xml file.

	qemu: Deal with stucked qemu on daemon startup
	If libvirt daemon gets restarted and there is (at least) one
	unresponsive qemu, the startup procedure hangs up. This patch creates
	one thread per vm in which we try to reconnect to monitor. Therefore,
	blocking in one thread will not affect other APIs.

	qemu: Introduce job queue size limit
	This patch creates an optional BeginJob queue size limit. When
	active, all other attempts above level will fail. To set this
	feature assign desired value to max_queued variable in qemu.conf.
	Setting it to 0 turns it off.

2011-09-06  Michal Privoznik  <mprivozn@redhat.com>

	daemon: Create priority workers pool
	This patch annotates APIs with low or high priority.
	In low set MUST be all APIs which might eventually access monitor
	(and thus block indefinitely). Other APIs may be marked as high
	priority. However, some must be (e.g. domainDestroy).

	For high priority calls (HPC), there are some high priority workers
	(HPW) created in the pool. HPW can execute only HPC, although normal
	worker can process any call regardless priority. Therefore, only those
	APIs which are guaranteed to end in reasonable small amount of time
	can be marked as HPC.

	The size of this HPC pool is static, because HPC are expected to end
	quickly, therefore jobs assigned to this pool will be served quickly.
	It can be configured in libvirtd.conf via prio_workers variable.
	Default is set to 5.

	To mark API with low or high priority, append priority:{low|high} to
	it's comment in src/remote/remote_protocol.x. This is similar to
	autogen|skipgen. If not marked, the generator assumes low as default.

	snapshot: wire up live qemu disk snapshots
	Lots of earlier patches led up to this point - the qemu snapshot_blkdev

	SELinux doesn't prevent qemu from open(O_CREAT) on the files.  There's
	still some followup work before things work with SELinux enforcing,

	There's still room for other improvements, too (for example, taking a
	disk snapshot of an inactive domain, by using qemu-img for both internal
	and external snapshots; wiring up delete and revert control, including

	snapshot: reject unimplemented disk snapshot features
	My RFC for snapshot support [1] proposes several rules for when it is

	the existence of new API flags.  These will be incrementally added
	in future patches, but until then, blindly mishandling a disk

	outright reject the attempts until the other pieces are in place,

	I got confused when 'virsh domblkinfo dom disk' required the

	snapshot: allow halting after snapshot
	Since a snapshot is fully recoverable, it is useful to have a
	snapshot as a means of hibernating a guest, then reverting to
	the snapshot to wake the guest up.  This mode of usage is
	similar to 'virsh save/virsh restore', except that virsh
	save uses an external file while virsh snapshot keeps the
	vm state internal to a qcow2 file.  However, it only works on
	persistent domains.

	In the usage pattern of snapshot/revert for hibernating a guest,
	there is no need to keep the guest running between the two points
	in time, especially since that would generate runtime state that
	would just be discarded.  Add a flag to make it possible to
	stop the domain after the snapshot has completed.

	snapshot: expose new delete flag in virsh
	It would technically be possible to have virsh compute the list

	a time.  But it's complex, and not worth writing for a first
	cut at implementing the new flags.

2011-09-05  Eric Blake  <eblake@redhat.com>

	snapshot: introduce new deletion flag
	Reverting to a state prior to an external snapshot risks
	corrupting any other branches in the snapshot hierarchy that
	were using the snapshot as a read-only backing file.  So
	disk snapshot code will default to preventing reverting to
	a snapshot that has any children, meaning that deleting just
	the children of a snapshot becomes a useful operation in
	preparing that snapshot for being a future reversion target.
	The code for the new flag is simple - it's one less deletion,
	plus a tweak to keep the current snapshot correct.

	* include/libvirt/libvirt.h.in
	(VIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN_ONLY): New flag.

	snapshot: reject transient disks where code is not ready
	The previous patch introduced new config, but if a hypervisor does
	not support that new config, someone can write XML that does not
	behave as documented.  This prevents some of those cases by
	explicitly rejecting transient disks for several hypervisors.

	Disk snapshots will require a new flag to actually affect a snapshot
	creation, so there's not much to reject there.

	snapshot: store qemu domain details in xml
	When reverting to a snapshot, the inactive domain configuration
	has to be rolled back to what it was at the time of the snapshot.
	Additionally, if the VM is active and the snapshot was active,
	this now adds a failure if the two configurations are ABI
	incompatible, rather than risking qemu confusion.

	A future patch will add a VIR_DOMAIN_SNAPSHOT_FORCE flag, which
	will be required for two risky code paths - reverting to an
	older snapshot that lacked full domain information, and reverting
	from running to a live snapshot that requires starting a new qemu
	process.  Any reverting that stops a running vm is also a form
	of data loss (discarding the current running state to go back in
	time), but as that is what reversion usually implies, it is
	probably not worth requiring a force flag.

	snapshot: allow full domain xml in snapshot
	Just like VM saved state images (virsh save), snapshots MUST
	track the inactive domain xml to detect any ABI incompatibilities.

	The indentation is not perfect, but functionality comes before form.

	Later patches will actually supply a full domain; for now, this
	wires up the storage to support one, but doesn't ever generate one
	in dumpxml output.

	Happily, libvirt.c was already rejecting use of VIR_DOMAIN_XML_SECURE
	from read-only connections, even though before this patch, there was
	no information to be secured by the use of that flag.

	And while we're at it, mark the libvirt snapshot metadata files

	snapshot: prevent migration from stranding snapshot data
	Migration is another case of stranding metadata.  And since
	snapshot metadata is arbitrarily large, there's no way to
	shoehorn it into the migration cookie of migration v3.

	This patch consolidates two existing locations for migration
	validation into one helper function, then enhances that function
	to also do the new checks.  If we could always trust the source
	to validate migration, then the destination would not have to
	do anything; but since older servers that did not do checking
	can migrate to newer destinations, we have to repeat some of
	the same checks on the destination; meanwhile, we want to
	detect failures as soon as possible.  With migration v2, this
	means that validation will reject things at Prepare on the
	destination if the XML exposes the problem, otherwise at Perform
	on the source; with migration v3, this means that validation
	will reject things at Begin on the source, or if the source
	is old and the XML exposes the problem, then at Prepare on the
	destination.

	This patch is necessarily over-strict.  Once a later patch
	properly handles auto-cleanup of snapshot metadata on the
	death of a transient domain, then the only time we actually
	need snapshots to prevent migration is when using the
	--undefinesource flag on a persistent source domain.

	It is possible to recreate snapshot metadata on the destination
	with VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and
	VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT.  But for now, that is limited,
	since if we delete the snapshot metadata prior to migration,
	then we won't know the name of the current snapshot to pass
	along; and if we delete the snapshot metadata after migration
	and use the v3 migration cookie to pass along the name of the
	current snapshot, then we need a way to bypass the fact that
	this patch refuses migration with snapshot metadata present.

	So eventually, we may have to introduce migration protocol v4
	that allows feature negotiation and an arbitrary number of
	handshake exchanges, so as to pass as many rpc calls as needed
	to transfer all the snapshot xml hierarchy.

	But all of that is thoughts for the future; for now, the best
	course of action is to quit early, rather than get into a
	funky state of stale metadata; then relax restrictions later.

	snapshot: support new undefine flags in qemu
	A nice benefit of deleting all snapshots at undefine time is that
	you don't have to do any reparenting or subtree identification - since
	everything goes, this is an O(n) process, whereas using multiple
	virDomainSnapshotDelete calls would be O(n^2) or worse.  But it is
	only doable for snapshot metadata, where we are in control of the
	data being deleted; for the actual snapshots, there's too much
	likelihood of something going wrong, and requiring even more API
	calls to figure out what failed in the meantime, so callers are
	better off deleting the snapshot data themselves one snapshot at
	a time where they can deal with failures as they happen.

	As more clients start to want to know this information, doing

	snapshot: teach virsh about new undefine flags
	Similar to 'undefine --managed-save' (commit 83e849c1), we must
	assume that the old API is unsafe; however, we cannot emulate
	metadata-only deletion on older servers.  Additionally, we have
	the wrinkle that while virDomainUndefineFlags and managed save
	cleanup were introduced in 0.9.4, it wasn't until 0.9.5 that
	snapshots block undefine of a domain.  Do the best we can given

2011-09-03  Eric Blake  <eblake@redhat.com>

	snapshot: prevent stranding snapshot data on domain destruction
	Just as leaving managed save metadata behind can cause problems
	when creating a new domain that happens to collide with the name
	of the just-deleted domain, the same is true of leaving any
	snapshot metadata behind.  For safety sake, extend the semantic
	change of commit b26a9fa9 to also cover snapshot metadata as a
	reason to reject undefining an inactive domain.  A future patch
	will make sure that shutdown of a transient domain automatically
	deletes snapshot metadata (whether by destroy, shutdown, or
	guest-initiated action).  Management apps of transient domains
	should take care to capture xml of snapshots, if it is necessary
	to recreate the snapshot metadata on a later transient domain
	with the same name and uuid.

	This also documents a new flag that hypervisors can choose to
	support as a shortcut for taking care of the metadata as part of
	the undefine process; however, nontrivial driver support for these
	flags will be deferred to future patches.

	Note that ESX and VBox can never be transient; therefore, they
	do not have to worry about automatic cleanup after shutdown
	(the persistent domain still remains); likewise they never
	store snapshot metadata, so the undefine flag is trivial.
	The nontrivial work remaining is thus in the qemu driver.

	Redefining a qemu snapshot requires a bit of a tweak to the common
	snapshot parsing code, but the end result is quite nice.

	Be careful that redefinitions do not introduce circular parent
	chains.  Also, we don't want to allow conversion between online
	and offline existing snapshots.  We could probably do some more
	validation for snapshots that don't already exist to make sure

	Supporting NO_METADATA on snapshot creation is interesting - we must
	still return a valid opaque snapshot object, but the user can't get
	anything out of it (unless we add a virDomainSnapshotGetName()),
	since it is no longer registered with the domain.

	Also, virsh now tries to query for secure xml, in anticipation of
	when we store <domain> xml inside <domainsnapshot>; for now, we
	can trivially support it, since we have nothing secure.

	from the fact that the older libvirt lost track of the current
	snapshot after a restart).  The snapshot-create-as command is
	intentionally not taught --redefine or --current, as this would
	imply adding a lot of other options for everything else that can
	appear in the <domainsnapshot> xml, but which is normally read-only.

	snapshot: allow recreation of metadata
	The first two flags are essential for being able to replicate
	snapshot hierarchies across multiple hosts, which will come in
	handy for supervised migrations.  It also allows a management app
	to take a snapshot of a transient domain, save the metadata, stop
	the domain, recreate a new transient domain by the same name,
	redefine the snapshot, then revert to it.

	This is not quite as convenient as leaving the metadata behind
	after a domain is no longer around, but doing that has a few
	problems: 1. the libvirt API can only delete snapshot metadata
	if there is a valid domain handle to use to get to that snapshot
	object - if stale data is left behind without a domain, there is
	no way to request that the data be cleaned up. 2. creating a new
	domain with the same name but different uuid than the older
	domain where a snapshot existed cannot use the older snapshot
	data; this risks confusing libvirt, and forbidding the stale
	data is similar to the recent patch to forbid stale managed save.

	The first two flags might be useful on hypervisors with no metadata,
	but only for modifying the notion of the current snapshot;
	however, I don't know how to do that for ESX or VBox.

	The third flag is a convenience option, to combine a creation with
	a delete metadata into one step.  It is trivial for hypervisors
	with no metadata.

	The qemu changes will be involved enough to warrant a separate patch.

	snapshot: allow deletion of just snapshot metadata
	A future patch will make it impossible to remove a domain if it
	would leave behind any libvirt-tracked metadata about snapshots,
	since stale metadata interferes with a new domain by the same name.
	But requiring snaphot contents to be deleted before removing a
	domain is harsh; with qemu, qemu-img can still make use of the
	contents after the libvirt domain is gone.  Therefore, we need
	an option to get rid of libvirt tracking information, but not
	the actual contents.  For hypervisors that do not track any

	snapshot: track current domain across deletion of children
	Deleting a snapshot and all its descendants had problems with
	tracking the current snapshot.  The deletion does not necessarily
	proceed in depth-first order, so a parent could be deleted
	before a child, wreaking havoc on passing the notion of the
	current snapshot to the parent.  Furthermore, even if traversal
	were depth-first, doing multiple file writes to pass current up

	snapshot: avoid crash when deleting qemu snapshots
	This one's nasty.  Ever since we fixed virHashForEach to prevent
	nested hash iterations for safety reasons (commit fba550f6),
	virDomainSnapshotDelete with VIR_DOMAIN_SNAPSHOT_DELETE_CHILDREN
	has been broken for qemu: it deletes children, while leaving
	grandchildren intact but pointing to a no-longer-present parent.
	But even before then, the code would often appear to succeed to
	clean up grandchildren, but risked memory corruption if you have
	a large and deep hierarchy of snapshots.

	For acting on just children, a single virHashForEach is sufficient.
	But for acting on an entire subtree, it requires iteration; and
	since we declared recursion as invalid, we have to switch to a
	while loop.  Doing this correctly requires quite a bit of overhaul,
	so I added a new helper function to isolate the algorithm from the
	actions, so that callers do not have to reinvent the iteration.

	Note that this _still_ does not handle CHILDREN correctly if one
	of the children is the current snapshot; that will be next.

	snapshot: properly revert qemu to offline snapshots
	Commit 5e47785 broke reverts to offline system checkpoint snapshots
	with older qemu, since there is no longer any code path to use
	qemu -loadvm on next boot.  Meanwhile, reverts to offline system
	checkpoints have been broken for newer qemu, both before and
	after that commit, since -loadvm no longer works to revert to
	disk state without accompanying vm state.  Fix both of these by
	using qemu-img to revert disk state.

	Meanwhile, consolidate the (now 3) clients of a qemu-img iteration
	over all disks of a VM into one function, so that any future
	algorithmic fixes to the FIXMEs in that function after partial
	loop iterations are dealt with at once.  That does mean that this

	snapshot: improve reverting to qemu paused snapshots
	If you take a checkpoint snapshot of a running domain, then pause

	you take a checkpoint of a paused domain, then run, then restore,
	there was a brief but non-deterministic window of time where the
	domain was running rather than paused.  Fix both of these

	Also, check that the VM is active every time lock is dropped
	between two monitor calls.

	snapshot: expose --running and --paused in virsh
	Pretty straight-forward exposure of new flags.  For most commands,
	we let the API reject mutually exclusive flags; but for save-image-edit,
	we do the sanity check ourselves to avoid looping on flag failure if
	the edit cycle is ever enhanced to allow the user to retry an edit
	to fix up an xml validation error.

	* tools/virsh.c (cmdManagedSave, cmdRestore, cmdSave)
	(cmdSaveImageDefine, cmdSaveImageEdit): Add new flags.
	* tools/virsh.pod (managedsave, restore, save, save-image-define)

	snapshot: fine-tune ability to start paused
	While it is nice that snapshots and saved images remember whether
	the domain was running or paused, sometimes the restoration phase
	wants to guarantee a particular state (paused to allow hot-plugging,
	or running without needing to call resume).  This introduces new
	flags to allow the control, and a later patch will implement the
	flags for qemu.

	* include/libvirt/libvirt.h.in (VIR_DOMAIN_SAVE_RUNNING)
	(VIR_DOMAIN_SAVE_PAUSED, VIR_DOMAIN_SNAPSHOT_REVERT_RUNNING)
	(VIR_DOMAIN_SNAPSHOT_REVERT_PAUSED): New flags.

	(virDomainManagedSave, virDomainSaveImageDefineXML)
	(virDomainRevertToSnapshot): Document their use, and enforce
	mutual exclusion.

2011-09-03  Eric Blake  <eblake@redhat.com>

	snapshot: better events when starting paused
	There are two classes of management apps that track events - one
	that only cares about on/off (and only needs to track EVENT_STARTED
	and EVENT_STOPPED), and one that cares about paused/running (also
	tracks EVENT_SUSPENDED/EVENT_RESUMED).  To keep both classes happy,
	any transition that can go from inactive to paused must emit two
	back-to-back events - one for started and one for suspended (since
	later resuming of the domain will only send RESUMED, but the first
	class isn't tracking that).

	This also fixes a bug where virDomainCreateWithFlags with the
	VIR_DOMAIN_START_PAUSED flag failed to start paused when restoring
	from a managed save image.

	* include/libvirt/libvirt.h.in (VIR_DOMAIN_EVENT_SUSPENDED_RESTORED)

	storage: Add virsh support for fs pool formating

2011-09-02  Osier Yang  <jyang@redhat.com>

	storage: Add fs pool formatting
	This patch adds the ability to make the filesystem for a filesystem
	pool during a pool build.

	The patch adds two new flags, no overwrite and overwrite, to control
	when mkfs gets executed.  By default, the patch preserves the
	current behavior, i.e., if no flags are specified, pool build on a
	filesystem pool only makes the directory on which the filesystem
	will be mounted.

	If the no overwrite flag is specified, the target device is checked
	to determine if a filesystem of the type specified in the pool is
	present.  If a filesystem of that type is already present, mkfs is
	not executed and the build call returns an error.  Otherwise, mkfs
	is executed and any data present on the device is overwritten.

	If the overwrite flag is specified, mkfs is always executed, and any
	existing data on the target device is overwritten unconditionally.

	qemu: detect incomplete save files
	Several users have reported problems with 'virsh start' failing because
	it was encountering a managed save situation where the managed save file
	was incomplete.  Be more robust to this by using two different magic
	numbers, so that newer libvirt can gracefully handle an incomplete file
	differently than a complete one, while older libvirt will at least fail
	up front rather than trying to load only to have qemu fail at the end.

	Managed save is a convenience - it exists to preserve as much state
	as possible; if the state was not preserved, it is reasonable to just
	log that fact, then proceed with a fresh boot.  On the other hand,
	user saves are under user control, so we must fail, but by making
	the failure message distinct, the user can better decide how to handle
	the situation of an incomplete save file.

	* src/qemu/qemu_driver.c (QEMUD_SAVE_PARTIAL): New define.
	(qemuDomainSaveInternal): Use it to mark incomplete images.
	(qemuDomainSaveImageOpen, qemuDomainObjRestore): Add parameter
	that controls what to do with partial images.
	(qemuDomainRestoreFlags, qemuDomainSaveImageGetXMLDesc)
	(qemuDomainSaveImageDefineXML, qemuDomainObjStart): Update callers.
	Based on an initial idea by Osier Yang.

	qemu: refactor file opening
	In a SELinux or root-squashing NFS environment, libvirt has to go
	through some hoops to create a new file that qemu can then open()
	by name.  Snapshots are a case where we want to guarantee an empty
	file that qemu can open; also, reopening a save file to convert it
	from being marked partial to complete requires a reopen to avoid
	O_DIRECT headaches.  Refactor some existing code to make it easier
	to reuse in later patches.

	* src/qemu/qemu_migration.h (qemuMigrationToFile): Drop parameter.
	* src/qemu/qemu_migration.c (qemuMigrationToFile): Let cgroup do

	lxc: do not require 'ifconfig' or 'ipconfig' in container
	Currently, the lxc implementation invokes 'ip' and 'ifconfig' commands
	inside a container using 'virRun'.  That has the side effect of requiring
	those commands to be present and to function in a manner consistent with
	the usage.  Some small roots (such as ttylinux) may not have 'ip' or
	'ifconfig'.

	This patch replaces the use of these commands with usage of
	netdevice.  The result is that lxc containers do not have to implement
	those commands, and lxc in libvirt is only dependent on the netdevice
	interface.

	I've tested this patch locally against the ubuntu libvirt version enough
	to verify its generally sane.  I attempted to build upstream today, but
	failed with:
	  /usr/bin/ld:
	    ../src/.libs/libvirt_driver_qemu.a(libvirt_driver_qemu_la-qemu_domain.o):

	Create ptmx as a device
	Hi,

	I'm seeing an issue with udev and libvirt-lxc.  Libvirt-lxc creates
	/dev/ptmx as a symlink to /dev/pts/ptmx.  When udev starts up, it
	checks the device type, sees ptmx is 'not right', and replaces it
	with a 'proper' ptmx.

	In lxc, /dev/ptmx is bind-mounted from /dev/pts/ptmx instead of being
	symlinked, so udev sees the right device type and leaves it alone.

	A patch like the following seems to work for me.  Would there be
	any objections to this?

	Subject: [PATCH 1/1] make ptmx a bind mount rather than symlink

	udev on some systems checks the device type of /dev/ptmx, and replaces it if
	not as expected.  The symlink created by libvirt-lxc therefore gets replaced.
	By creating it as a bind mount, the device type is correct and udev leaves it
	alone.

	BlockPull: Set initial bandwidth limit if specified
	The libvirt BlockPull API supports the use of an initial bandwidth limit but the
	qemu block_stream API does not.  To get the desired behavior we use the two APIs
	strung together: first BlockPull, then BlockJobSetSpeed.  We can do this at the
	driver level to avoid duplicated code in each monitor path.

2011-09-02  Adam Litke  <agl@us.ibm.com>

	BlockJob: Bandwidth parameter is in MB when using text monitor
	Due to an unfortunate precedent in qemu, the units for the bandwidth parameter
	to block_job_set_speed are different between the text monitor and the qmp
	monitor.  While the qmp monitor uses bytes/s, the text monitor expects MB/s.

	Fix tracking of RPC messages wrt streams
	Commit 2c85644b0b51fbe5b6244e6773531af29933a727 attempted to
	fix a problem with tracking RPC messages from streams by doing

	-            if (msg->header.type == VIR_NET_REPLY) {
	+            if (msg->header.type == VIR_NET_REPLY ||
	+                (msg->header.type == VIR_NET_STREAM &&
	+                 msg->header.status != VIR_NET_CONTINUE)) {
	                 client->nrequests--;

	In other words any stream packet, with status NET_OK or NET_ERROR
	would cause nrequests to be decremented. This is great if the
	packet from from a synchronous virStreamFinish or virStreamAbort
	API call, but wildly wrong if from a server initiated abort.
	The latter resulted in 'nrequests' being decremented below zero.
	This then causes all I/O for that client to be stopped.

	Instead of trying to infer whether we need to decrement the
	nrequests field, from the message type/status, introduce an
	explicit 'bool tracked' field to mark whether the virNetMessagePtr
	object is subject to tracking.

	Also add a virNetMessageClear function to allow a message
	contents to be cleared out, without adversely impacting the
	'tracked' field as a naive memset() would do

	* src/rpc/virnetmessage.c, src/rpc/virnetmessage.h: Add
	  a 'bool tracked' field and virNetMessageClear() API
	* daemon/remote.c, daemon/stream.c, src/rpc/virnetclientprogram.c,

	Avoid use-after-free on streams, due to message callbacks
	When sending outbound stream RPC messages, a callback is

	Fix memory leak dispatching domain events
	When dispatching domain events we will create an XDR struct
	containing the event info. Some of this data may be allocated

	the events have a dom->name string that needs freeing. The code
	should have used the xdr_free() procedure for doing all this

	Don't leak memory if a cgroup is mounted multiple times
	It is possible (expected/likely in Fedora 15) for a cgroup controller
	to be mounted in multiple locations at the same time, due to bind

	snapshot: forbid snapshot on autodestroy domain
	There is no reason to forbid pausing an autodestroy domain
	(not to mention that 'virsh start --paused --autodestroy'

	Meanwhile, qemu was failing to enforce the API documentation that

	Back in 2008 when this line of util.h was written, gnulib's verify

	in combination with our choice of gcc -W options.  But that has
	since been fixed in gnulib, and newer gnulib even maps verify()
	to the C1x feature of _Static_assert, which gives even nicer

	with the simpler verify().

	hyperv: Add basic driver for Microsoft Hyper-V
	Domain listing, basic information retrieval and domain life cycle

	The driver uses OpenWSMAN to directly communicate with a Hyper-V

	The driver is based on the work of Michael Sievers. This started in
	the same master program project group at the University of Paderborn
	as the ESX driver.

	Fix persistent migration config save
	When a user migrates a domain by command as

	libvirt saves vm's domain XML config in destination host after migration.
	But it saves vm->def. Then, the saved XML contains some garbage.

	  ...

	rpc: Don't close connection if program is unknown
	In case we add a new program in the future (we did that in the past and
	we are going to do it again soon) current daemon will behave badly with
	new client that wants to use the new program. Before the RPC rewrite we
	used to just send an error reply to any request with unknown program.
	With the RPC rewrite in 0.9.3 the daemon just closes the connection
	through which such request was sent. This patch fixes this regression.

2011-08-26  Daniel P. Berrange  <berrange@redhat.com>

	Fix keymap used to talk with QEMU
	The QEMU 'sendkey' command expects keys to be encoded in the same
	way as the RFB extended keycode set. Specifically it wants extended
	keys to have the high bit of the first byte set, while the Linux
	XT KBD driver codeset uses the low bit of the second byte. To deal
	with this we introduce a new keymap 'RFB' and use that in the QEMU
	driver

	* include/libvirt/libvirt.h.in: Add VIR_KEYCODE_SET_RFB

	virsh: Clarify documentation of -d option
	The default is 4, not 0.

	qemu: Correctly label migration TCP socket

	security: Introduce SetSocketLabel
	This API labels all sockets created until ClearSocketLabel is called in
	a way that a vm can access them (i.e., they are labeled with svirt_t
	based label in SELinux).

	security: Rename SetSocketLabel APIs to SetDaemonSocketLabel
	The APIs are designed to label a socket in a way that the libvirt daemon
	itself is able to access it (i.e., in SELinux the label is virtd_t based
	as opposed to svirt_* we use for labeling resources that need to be
	accessed by a vm). The new name reflects this.

	Ignore unused streams in virStreamAbort
	When virStreamAbort is called on a stream that has not been used yet,
	quite confusing error is returned: "this function is not supported by
	the connection driver". Let's just ignore such streams as there's
	nothing to abort anyway.

	Do not try to cancel non-existent migration on source
	If migration failed on source daemon, the migration is automatically
	canceled by the daemon itself. Thus we don't need to call
	virDomainMigrateConfirm3(cancelled=1). Calling it doesn't cause any harm
	but the resulting error message printed in logs may confuse people.

	snapshot: track current snapshot across restarts

2011-08-26  Eric Blake  <eblake@redhat.com>

	snapshot: only pass snapshot to qemu command line when reverting
	Changing the current vm, and writing that change to the file
	system, all before a new qemu starts, is risky; it's hard to
	roll back if starting the new qemu fails for some reason.
	Instead of abusing vm->current_snapshot and making the command
	line generator decide whether the current snapshot warrants
	using -loadvm, it is better to just directly pass a snapshot all
	the way through the call chain if it is to be loaded.

	This frees up the last use of snapshot->def->active for qemu's
	use, so the next patch can repurpose that field for tracking
	which snapshot is current.

	* src/qemu/qemu_command.c (qemuBuildCommandLine): Don't use active
	field of snapshot.
	* src/qemu/qemu_process.c (qemuProcessStart): Add a parameter.

	snapshot: don't leak resources on qemu snapshot failure
	https://bugzilla.redhat.com/show_bug.cgi?id=727709
	mentions that if qemu fails to create the snapshot (such as what
	happens on Fedora 15 qemu, which has qmp but where savevm is only
	in hmp, and where libvirt is old enough to not try the hmp fallback),
	then 'virsh snapshot-list dom' will show a garbage snapshot entry,
	and the libvirt internal directory for storing snapshot metadata
	will have a bogus file.

	This fixes the fallout bug of polluting the snapshot-list with
	garbage on failure (the root cause of the F15 bug of not having
	fallback to hmp has already been fixed in newer libvirt releases).

	* src/qemu/qemu_driver.c (qemuDomainSnapshotCreateXML): Allocate
	memory before making snapshot, and cleanup on failure.  Don't

	Fix command test wrt gnutls initialize & fix debugging
	The VIR_TEST_DEBUG and VIR_TEST_VERBOSE env vars did not work
	because we replaced 'environ' with 'newenv'. Simply calling
	virTestGetDebug/Verbose() before replacing the 'environ' ensures
	we have processed the env variables.

	The gnutls initialization code opens /dev/urandom and keeps that
	FD around for later use. We have code which kills off FDs 3-5
	to avoid interfereing with our test case. Move the virInitialize

	util: only fchown newly created files in virFileOpenAs
	virFileOpenAs takes desired uid:gid as arguments, and not only uses
	them for a fork/setuid/setgid when retrying failed open operations,
	but additionally always forces the opened file to be owned by the
	given uid:gid.

	One example of the problems this causes is that, when restoring a
	domain from a file that is owned by the qemu user, opening the file
	chowns it to root. if dynamic_ownership=1 this is coincidentally
	expected, but if dynamic_ownership=0, no existing file should ever
	have its ownership changed.

	This patch adds an extra check before calling fchown() - it only does
	it if O_CREAT was passed to virFileOpenAs() in the openflags.

	Special case is changes on lxcDomainInterfaceStats, if it's not
	implemented on the platform, prints error like:

	    lxcError(VIR_ERR_OPERATION_INVALID, "%s",
	             _("interface stats not implemented on this platform"));

	As the function is supported by driver actually, error like
	VIR_ERR_NO_SUPPORT is confused.

	build: work around older systemtap header
	Systemtap 1.2 <sys/sdt.h> tried to expand STAP_PROBE3 into an
	initialization:
	  volatile __typeof__(arg) foo = arg;
	but that fails if arg was declared as 'char arg[100]'.
	Rather than make all callers to PROBE deal with the stupidity
	of <sys/sdt.h>, we instead make PROBE cast away the problem.
	Some of this preprocessor abuse copies ideas in src/libvirt.c.

	Revert "xen: Allow to undefine a running domain (xm_internal)"
	ACK was given too soon.  According to the code, the xm driver is
	only used for inactive domains, and has no notion of an active
	domain, thus, it cannot support undefine of a running domain.
	The real fix for xen needs to be in the unified driver and/or
	the xend level.

	This reverts commit 49186deda62161599877b0de6f7f4345c50d842a.

	daemon: initialize GnuTLS
	When spice_tls is set but listen_tls is not, we don't initialize
	GnuTLS library. So any later gnutls call (e.g. during migration,
	where we initialize a certificate) will access uninitialized GnuTLS
	internal structs and throws an error.

	Although, we might now initialize GnuTLS twice, it is safe according
	to the documentation:

	    This function can be called many times,
	    but will only do something the first time.

	This patch creates 2 functions: virNetTLSInit and virNetTLSDeinit
	with respect to written above.

	Ensure async packets never get marked for sync replies
	If a client had initiated a stream abort, it will have a call
	waiting for a reply in the queue. If more data continues to

	Don't attempt to read from a stream if it is closed
	The I/O event callback processes incoming packets first, and then
	does outgoing packets. If the incoming packet caused the stream to
	close, then the attempt to process outgoing data resulted in an
	error. This caused libvirt to then send an error back to the client,
	but the stream had already been stopped. This confused the client
	since it sees 2 error events.

	Fix race condition in abort of stream
	If a stream gets a server initiated abort, the client may still
	send an abort request before it receives the server side abort.
	This causes the server to send back another abort for the
	stream. Since the protocol defines that abort is the last thing
	to be sent, the client gets confused by this second abort from
	the server. If the stream is already shutdown, just drop any
	client requested abort, rather than sending back another message.
	This fixes the regression from previous versions.

	Tested as follows

	In one virsh session

	  virsh # start foo
	  virsh # console foo

	In other virsh session

	  virsh # destroy foo

	The first virsh session should be able to continue issuing
	commands without error. Prior to this patch it saw

	  virsh # list
	  error: Failed to list active domains
	  error: An error occurred, but the cause is unknown

	  virsh # list
	  error: Failed to list active domains
	  error: no call waiting for reply with prog 536903814 vers 1 serial 9

2011-08-17  Daniel P. Berrange  <berrange@redhat.com>

	Ensure client streams are closed when marking a client for close
	Every active stream results in a reference being held on the
	virNetServerClientPtr object. This meant that if a client quit
	with any streams active, although all I/O was stopped the
	virNetServerClientPtr object would leak. This causes libvirtd
	to leak any file handles associated with open streams when a
	client quit

	To fix this, when we call virNetServerClientClose there is a
	callback invoked which lets the daemon release the streams
	and thus the extra references

	* daemon/remote.c: Add a hook to close all streams
	* daemon/stream.c, daemon/stream.h: Add API for releasing
	  all streams
	* src/rpc/virnetserverclient.c, src/rpc/virnetserverclient.h:

	pciDeviceNetName: Function to get the network device name of a pci device
	pciConfigAddressCompare: Function to compare pci config addresses

	pci: Move some pci sriov helper code out of node device driver to util/pci

	qemu: support event_idx parameter for virtio disk and net devices
	In some versions of qemu, both virtio-blk-pci and virtio-net-pci
	devices can have an event_idx setting that determines some details of
	event processing. When it is enabled, it "reduces the number of
	interrupts and exits for the guest". qemu will automatically enable
	this feature when it is available, but there may be cases where this
	new feature could actually make performance worse (NB: no such case
	has been found so far).

	As a safety switch in case such a situation is encountered in the
	field, this patch adds a new attribute "event_idx" to the <driver>
	element of both disk and interface devices. event_idx can be set to
	"on" (to force event_idx on in case qemu has it disabled by default)
	or "off" (for force event_idx off). In the case that event_idx support
	isn't present in qemu, the attribute is ignored (this on the advice of
	the qemu developer).

2011-08-13  Daniel P. Berrange  <berrange@redhat.com>

	Add some APIs which use locking for crashsafe pidfile handling
	In daemons using pidfiles to protect against concurrent
	execution there is a possibility that a crash may leave a stale

	To avoid this problem, introduce a pair of APIs which make
	use of virFileLock to ensure crash-safe & race condition-safe
	pidfile acquisition & releae

	* src/libvirt_private.syms, src/util/virpidfile.c,

	Introduce functions for checking whether a pidfile is valid
	In some cases the caller of virPidFileRead might like extra checks

	the pid is still alive with kill(0, -1), and (on linux only) will
	look at /proc/$PID/path

	We forgot to add virDomainUndefineFlags for a couple of hypervisors.
	This wires up trivial versions (since neither hypervisor supports

	virsh: don't reject undefine on active domain
	The public API documents that undefine may be used to transition a
	running persistent domain into a transient one.  Many drivers still
	do not support this usage, but virsh shouldn't be getting in the
	way of those that do support it.

	This also drops a redundant conditional; vshCommandOptString
	guaranteed that name was non-NULL.

	* tools/virsh.c (cmdUndefine): Allow undefine on active domains;
	the drivers may still reject it, but it is a valid API usage.
	* tests/undefine (error): Fix the test to match.

	Improve tokenizing of linkable terms
	Currently only tabs and blanks are used for tokenizing the description,
	which breaks when a term is at the end of a line or has () appended to

	   return for splitting.
	2. Remove some common non-word characters from the token before lookup.

	network: eliminate potential memory leak on parse failure
	While the first encountered dns host record is being parsed, it's
	possible for virNetworkDef::hosts to point to memory that has been
	allocated, but virNetworkDef::nhosts to still be 0. If there is a
	failure during that time, virNetworkDef::hosts will be leaked.

	Although this isn't currently the case for virNetworkDef::txtrecords,
	it could become that way through future re-factoring, and it hurts
	nothing to restructure the freeing of txtrecord data to match that of
	hosts data.

	qemu: Fix -chardev udp if parameters are omitted
	The following XML:

	    <serial type='udp'>
	      <source mode='connect' service='9999'/>
	    </serial>

	is accepted by domain_conf.c but maps to the qemu command line:

	-chardev udp,host=127.0.0.1,port=2222,localaddr=(null),localport=(null)

	qemu can cope with everything omitting except the connection port, which
	seems to also be the intent of domain_conf validation, so let's not
	generate bogus command lines for that case.
	The defaults are empty strings for addresses and 0 for the localport

	Additionally, tweak the qemu cli parsing to handle omitted host
	parameters
	for -serial udp

	managedsave: prohibit use on transient domains
	Transient domains reject attempts to set autostart, and using
	virDomainCreate to restart a domain only works on persistent
	domains.  Therefore, managed save makes no sense on transient
	domains, and should be rejected up front rather than creating
	an otherwise unrecoverable managed save file.

	Besides, transient domains imply that a lot more management is
	being done by the upper layer; this includes the assumption
	that the upper layer is okay managing the saved state file
	created by virDomainSave, and does not need to use managed save.

	* src/libvirt.c: Document that transient domains are incompatible
	with managed save.
	* src/qemu/qemu_driver.c (qemuDomainManagedSave): Enforce it.

2011-08-08  Daniel P. Berrange  <berrange@redhat.com>

	Allow use of file images for LXC container filesystems
	A previous commit gave the LXC driver the ability to mount
	block devices for the container filesystem. Through use of
	the loopback device functionality, we can build on this to
	support use of plain file images for LXC filesytems.

	By setting the LO_FLAGS_AUTOCLEAR flag we can ensure that
	the loop device automatically disappears when the container
	dies / shuts down

	* src/lxc/lxc_container.c: Raise error if we see a file
	  based filesystem, since it should have been turned into
	  a loopback device already

	Allow use of block devices for guest filesystem
	Currently the LXC driver can only populate filesystems from

	block devices to be mounted. It autodetects the filesystem

	network: eliminate lag in updating dnsmasq hosts files
	This addresses https://bugzilla.redhat.com/show_bug.cgi?id=713728

	When "defining" a new network (or one that exists but isn't currently
	active) the new definition is stored in network->def, but for a
	network that already exists and is active, the new definition is
	stored in network->newDef, and then moved over to network->def as soon
	as the network is destroyed.

	However, the code that writes the dhcp and dns hosts files used by
	dnsmasq was always using network->def for its information, even when
	the new data was actually in network->newDef, so the hosts files
	always lagged one edit behind the definition.

	This patch changes the code to keep the pointer to the new definition
	after it's been assigned into the network, and use it directly
	(regardless of whether it's stored in network->newDef or network->def)
	to construct the hosts files.

	openvz: detect when a domain was shut down from the inside
	This patch adds an internal function openvzGetVEStatus to
	get the real state of the domain. This function is used in
	various places in the driver, in particular to detect when
	the domain has been shut down by the user with the "halt"
	command.

	qemu: fix crash when mixing sync and async monitor jobs
	Currently, we attempt to run sync job and async job at the same time. It
	means that the monitor commands for two jobs can be run in any order.

	In the function qemuDomainObjEnterMonitorInternal():
	    if (priv->job.active == QEMU_JOB_NONE && priv->job.asyncJob) {
	        if (qemuDomainObjBeginNestedJob(driver, obj) < 0)
	We check whether the caller is an async job by priv->job.active and
	priv->job.asynJob. But when an async job is running, and a sync job is
	also running at the time of the check, then priv->job.active is not
	QEMU_JOB_NONE. So we cannot check whether the caller is an async job
	in the function qemuDomainObjEnterMonitorInternal(), and must instead
	put the burden on the caller to tell us when an async command wants
	to do a nested job.

	Once the burden is on the caller, then only async monitor enters need
	to worry about whether the VM is still running; for sync monitor enter,
	the internal return is always 0, so lots of ignore_value can be dropped.

	qemu: Fix a regression of domjobabort
	Introduced by f9a837da73a11ef, the condition is not changed after
	the else clause is removed. So now it quit with "domain is not
	running" when the domain is running. However, when the domain is
	not running, it reports "no job is active".

	How to reproduce:

	1)
	% virsh start $domain
	% virsh domjobabort $domain
	error: Requested operation is not valid: domain is not running

	2)
	% virsh destroy $domain
	% virsh domjobabort $domain
	error: Requested operation is not valid: no job is active on the domain

	3)

	network: don't forward DNS requests from isolated networks
	This is in response to:

	  https://bugzilla.redhat.com/show_bug.cgi?id=723862

	which points out that a guest on an "isolated" network could
	potentially exploit the DNS forwarding provided by dnsmasq to create a
	communication channel to the outside.

	This patch eliminates that possibility by adding the "--no-resolv"
	argument to the dnsmasq commandline, which tells dnsmasq to not
	forward on any requests that it can't resolve itself (by looking at
	its own static hosts files and runtime list of dhcp clients), but to
	instead return a failure for those requests.

	This shouldn't cause any undesirable change from current
	behavior, even in the case where a guest is currently configured with
	multiple interfaces, one of them being connected to an isolated
	network, and another to a network that does have connectivity to the
	outside. If the isolated network's DNS server is queried for a name
	it doesn't know, it will return "Refused" rather than "Unknown", which
	indicates to the guest that it should query other servers, so it then
	queries the connected DNS server, and gets the desired response.

	freebsd: Fix build problem due to picking up the wrong libvirt.h
	Gettext annoyingly modifies CPPFLAGS in-place, putting
	-I/usr/local/include into the search patch if libintl headers
	must be used from that location.  But since we must support
	automake 1.9.6 which lacks AM_CPPFLAGS, and since CPPFLAGS is used
	prior to INCLUDES, this means that the build picks up the _old_
	installed libvirt.h in priority to the in-tree version, leading
	to all sorts of weird build failures on FreeBSD.

	Fix this by teaching configure to undo gettext's actions, but
	to keep any changes required by gettext at the end of INCLUDES
	after all in-tree locations are used first.  Also requires
	adding a wrapper Makefile.am and making gnulib-tool create
	just gnulib.mk files during the bootstrap process.

	libxl: fix build failure due to change in virDomainGraphicsDef
	This failure was introduced by commit dacee3d, which removed
	listenAddr from the unions in virDomainGraphicsDef in favor of putting
	it in the address attribute of virDomainGraphicsListenDef.

2011-07-29  Laine Stump  <laine@laine.org>

	qemu: support type=network in domain graphics <listen>
	The domain XML now understands the <listen> subelement of its
	<graphics> element (including when listen type='network'), and the
	network driver has an internal API that will turn a network name into
	an IP address, so the final logical step is to put the glue into the
	qemu driver so that when it is starting up a domain, if it finds
	<listen type='network' network='xyz'/> in the XML, it will call the
	network driver to get an IPv4 address associated with network xyz, and
	tell qemu to listen for vnc (or spice) on that address rather than the
	default address (localhost).

	The motivation for this is that a large installation may want the
	guests' VNC servers listening on physical interfaces rather than
	localhost, so that users can connect directly from the outside; this
	requires sending qemu the appropriate IP address to listen on. But
	this address will of course be different for each host, and if a guest
	might be migrated around from one host to another, it's important that
	the guest's config not have any information embedded in it that is
	specific to one particular host. <listen type='network.../> can solve
	this problem in the following manner:

	  1) on each host, define a libvirt network of the same name,
	     associated with the interface on that host that should be used
	     for listening (for example, a simple macvtap network: <forward
	     mode='bridge' dev='eth0'/>, or host bridge network: <forward
	     mode='bridge'/> <bridge name='br0'/>

	  2) in the <graphics> element of each guest's domain xml, tell vnc to
	     listen on the network name used in step 1:

	     <graphics type='vnc' port='5922'>
	       <listen type='network'network='example-net'/>
	     </graphics>

	(all the above also applies for graphics type='spice').

2011-07-29  Laine Stump  <laine@laine.org>

	conf: add <listen> subelement to domain <graphics> element
	Once it's plugged in, the <listen> element will be an optional
	replacement for the "listen" attribute that graphics elements already
	have. If the <listen> element is type='address', it will have an
	attribute called 'address' which will contain an IP address or dns
	name that the guest's display server should listen on. If, however,
	type='network', the <listen> element should have an attribute called
	'network' that will be set to the name of a network configuration to
	get the IP address from.

	* docs/schemas/domain.rng: updated to allow the <listen> element

	* docs/formatdomain.html.in: document the <listen> element and its
	  attributes.

	* src/conf/domain_conf.[hc]:

	  1) The domain parser, formatter, and data structure are modified to
	     support 0 or more <listen> subelements to each <graphics>
	     element. The old style "legacy" listen attribute is also still
	     accepted, and will be stored internally just as if it were a
	     separate <listen> element. On output (i.e. format), the address
	     attribute of the first <listen> element of type 'address' will be
	     duplicated in the legacy "listen" attribute of the <graphic>
	     element.

	  2) The "listenAddr" attribute has been removed from the unions in
	     virDomainGRaphicsDef for graphics types vnc, rdp, and spice.
	     This attribute is now in the <listen> subelement (aka
	     virDomainGraphicsListenDef)

	  3) Helper functions were written to provide simple access
	     (both Get and Set) to the listen elements and their attributes.

	* src/libvirt_private.syms: export the listen helper functions

	* src/qemu/qemu_command.c, src/qemu/qemu_hotplug.c,
	  src/qemu/qemu_migration.c, src/vbox/vbox_tmpl.c,
	  src/vmx/vmx.c, src/xenxs/xen_sxpr.c, src/xenxs/xen_xm.c

	  Modify all these files to use the listen helper functions rather
	  than directly referencing the (now missing) listenAddr
	  attribute. There can be multiple <listen> elements to a single
	  <graphics>, but the drivers all currently only support one, so all
	  replacements of direct access with a helper function indicate index
	  "0".

	* tests/* - only 3 of these are new files added explicitly to test the
	  new <listen> element. All the others have been modified to reflect
	  the fact that any legacy "listen" attributes passed in to the domain
	  parse will be saved in a <listen> element (i.e. one of the
	  virDomainGraphicsListenDefs), and during the domain format function,
	  both the <listen> element as well as the legacy attributes will be
	  output.

	Fix race in ref counting when handling RPC jobs
	When an incoming RPC message is ready for processing,

	  virNetServerClientDispatchRead()

	will invoke the 'dispatchFunc' callback. This is set to

	  virNetServerDispatchNewMessage

	This function puts the message + client in a queue for processing by the thread
	pool. The thread pool worker function is

	  virNetServerHandleJob

	The first thing this does is acquire an extra reference on the 'client'.

	Unfortunately, between the time the message+client are put on the thread pool
	queue, and the time the worker runs, the client object may have had its last
	reference removed.

	We clearly need to add the reference to the client object before putting the

	util: change virFile*Pid functions to return < 0 on failure
	Although most functions in libvirt return 0 on success and < 0 on
	failure, there are a few functions lingering around that return errno
	(a positive value) on failure, and sometimes code calling those
	functions incorrectly assumes the <0 standard. I noticed one of these
	the other day when auditing networkStartDhcpDaemon after Guido Gunther
	found a place where success was improperly returned on failure (that
	patch has been acked and is pending a push). The problem was that it
	expected the return value from virFileReadPid to be < 0 on failure,
	but it was actually positive (it was also neglected to set the return
	code in this case, similar to the bug found by Guido).

	This all led to the fact that *all* of the virFile*Pid functions in
	util.c are returning errno on failure. This patch remedies that
	problem by changing them all to return -errno on failure, and makes
	any necessary changes to callers of the functions. (In the meantime, I
	also properly set the return code on failure of virFileReadPid in
	networkStartDhcpDaemon).

	semantics of the 'expire_offset' field in the test case struct
	so that instead of being an absolute timestamp, it was a delta
	relative to the current time. This broke the test cases which
	were testing expiry of certificates, by putting the expiry
	time into the future, instead of in the past.

	network: provide internal API to return IP of a network
	The new listenNetwork attribute needs to learn an IP address based on a
	named network. This patch provides a function networkGetNetworkAddress
	which provides that.

	Some networks have an IP address explicitly in their configuration
	(ie, those with a forward type of "none", "route", or "nat"). For
	those, we can just return the IP address from the config.

	The rest will have a physical device associated with them (either via
	<bridge name='...'/>, <forward ... dev='...'/>, or possibly via a pool
	of interfaces inside the network's <forward> element) and we will need
	to ask the kernel for a current IP address of that device (via the
	newly added ifaceGetIPAddress)

	If networkGetNetworkAddress encounters an error while trying to learn
	the address for a network, it will return -1. In the case that libvirt
	has been compiled without the network driver, the call is a macro
	which reduces to -2. This allows differentiating between a failure of
	the network driver, and its complete absence.

2011-07-25  Laine Stump  <laine@laine.org>

	util: add an ifaceGetIPAddress to the interface utilities
	This function uses ioctl(SIOCGIFADDR), which limits it to returning
	the first IPv4 address of an interface, but that's what we want right
	now (the place we're going to use the address only accepts one).

	util: make interface.c functions consistently return < 0 on error
	All of the functions in util/interface.c were returning 0 on success,
	but some returned -1 on error, and some returned a positive value
	(usually the value of errno, but sometimes just 1). Libvirt's standard
	is to return < 0 on error (in the case of functions that need to
	return errno, -errno is returned.

	This patch modifies all functions in interface.c to consistently
	return < 0 on error, and makes changes to callers of those functions
	where necessary.

	Refactor the certification validation code
	There is some commonality between the code for sanity checking
	certs when initializing libvirt and the code for validating
	certs during a live TLS session handshake. This patchset splits
	up the sanity checking function into several smaller functions
	each doing a specific type of check. The cert validation code
	is then updated to also call into these functions

	save: new API to manipulate save file images
	Modifying the xml on either save or restore only gets you so
	far - you have to remember to 'virsh dumpxml dom' just prior
	to the 'virsh save' in order to have an xml file worth modifying
	that won't be rejected due to abi breaks.  To make this more
	powerful, we need a way to grab the xml embedded within a state
	file, and from there, it's not much harder to also support
	modifying a state file in-place.

	save: add virFileDirectFd wrapper type
	O_DIRECT has stringent requirements.  Rather than make lots of changes
	at each site that wants to use O_DIRECT, it is easier to offload
	the work through a helper process that mirrors the I/O between a
	pipe and the actual direct fd, so that the other end of the pipe
	no longer has to worry about constraints.

	Plus, if the kernel ever gains better posix_fadvise support, then we
	only have to touch a single file to let all callers benefit from a
	more efficient way to avoid file system caching.

	save: let iohelper work on O_DIRECT fds
	Required for a coming patch where iohelper will operate on O_DIRECT
	fds.  There, the user-space memory must be aligned to file system
	boundaries (at least 512, but using page-aligned works better, and
	some file systems prefer 64k).  Made tougher by the fact that
	VIR_ALLOC won't work on void *, but posix_memalign won't work on
	char * and isn't available everywhere.

	This patch makes some simplifying assumptions - namely, output
	to an O_DIRECT fd will only be attempted on an empty seekable
	file (hence, no need to worry about preserving existing data
	on a partial block, and ftruncate will work to undo the effects
	of having to round up the size of the last block written), and
	input from an O_DIRECT fd will only be attempted on a complete
	seekable file with the only possible short read at EOF.

	* configure.ac (AC_CHECK_FUNCS_ONCE): Check for posix_memalign.
	* src/util/iohelper.c (runIO): Use aligned memory, and handle
	quirks of O_DIRECT on last write.

2011-07-22  Eric Blake  <eblake@redhat.com>

	save: let iohelper handle inherited fd
	Rather than making the iohelper subject to a race in reopening
	the file, it is nicer to pass an already-open fd by inheritance.

	The old synopsis form must continue to work - if someone updates
	their libvirt package and installs a new libvirt_iohelper but
	without restarting the old libvirtd daemon, then the daemon can
	still make calls using the old syntax but the new iohelper.

	* src/util/iohelper.c (runIO): Split code for open...
	(prepare): ...to new function.
	(usage): Update synopsis.

	For all hypervisors that support save and restore, the new API

	error: add new error type for reflecting partial API support
	VIR_ERR_INVALID_ARG implies that an argument cannot possibly
	be correct, given the current state of the API.
	VIR_ERR_CONFIG_UNSUPPORTED implies that a configuration is
	wrong, but arguments aren't configuration.
	VIR_ERR_NO_SUPPORT implies that a function is completely
	unimplemented.

	But in the case of a function that is partially implemented,
	yet the full power of the API is not available for that
	driver, none of the above messages make sense.  Hence a new
	error message, implying that the argument is known to comply
	with the current state of the API, and that while the driver
	supports aspects of the function, it does not support that
	particular use of the argument.

	A good use case for this is a driver that supports
	virDomainSaveFlags, but not the dxml argument of that API.

	It might be feasible to also use this new error for all functions
	that check flags, and which accept fewer flags than what is possible
	in the public API.  But doing so would get complicated, since
	neither libvirt.c nor the remote driver may do flag filtering,
	and every other driver would have to do a two-part check, first
	using virCheckFlags on all public flags (which gives
	VIR_ERR_INVALID_ARG for an impossible flag), followed by a
	particular mask check for VIR_ERR_ARGUMENT_UNSUPPORTED (for a
	possible public flag but unsupported by this driver).

	* include/libvirt/virterror.h (VIR_ERR_ARGUMENT_UNSUPPORTED): New
	error.
	* src/util/virterror.c (virErrorMsg): Give it a message.
	Suggested by Daniel P. Berrange.

	network: internal API functions to manage assignment of physdev to guest
	The network driver needs to assign physical devices for use by modes
	that use macvtap, keeping track of which physical devices are in use
	(and how many instances, when the devices can be shared). Three calls
	are added:

	networkAllocateActualDevice - finds a physical device for use by the
	domain, and sets up the virDomainActualNetDef accordingly.

	networkNotifyActualDevice - assumes that the domain was already
	running, but libvirtd was restarted, and needs to be notified by each
	already-running domain about what interfaces they are using.

	networkReleaseActualDevice - decrements the usage count of the
	allocated physical device, and frees the virDomainActualNetDef to
	avoid later accidentally using the device.

	bridge_driver.[hc] - the new APIs. When WITH_NETWORK is false, these
	functions are all #defined to be "0" in the .h file (effectively
	becoming a NOP) to prevent link errors.

	qemu_(command|driver|hotplug|process).c - add calls to the above APIs
	    in the appropriate places.

	tests/Makefile.am - we need to include libvirt_driver_network.la
	    whenever libvirt_driver_qemu.la is linked, to avoid unreferenced
	    symbols (in functions that are never called by the test
	    programs...)

2011-07-22  Laine Stump  <laine@laine.org>

	qemu: use virDomainNetGetActual*() in qemuDomainXMLToNative
	This is the one function outside of domain_conf.c that plays around
	with (even modifying) the internals of the virDomainNetDef, and thus
	can't be fixed up simply by replacing direct accesses to the fields of
	the struct with the GetActual*() access functions.

	In this case, we need to check if the defined type is "network", and
	if it is *then* check the actual type; if the actual type is "bridge",
	then we can at least put the bridgename in a place where it can be
	used; otherwise (if type isn't "bridge"), we behave exactly as we used
	to - just null out *everything*.

2011-07-22  Laine Stump  <laine@laine.org>

	qemu: use virDomainNetGetActual*() functions where appropriate
	The qemu driver accesses fields in the virDomainNetDef directly, but
	with the advent of the virDomainActualNetDef, some pieces of
	information may be found in a different place (the ActualNetDef) if
	the network connection is of type='network' and that network is of
	forward type='bridge|private|vepa|passthrough'. The previous patch
	added functions to mask this difference from callers - they hide the
	decision making process and just pick the value from the proper place.

	This patch uses those functions in the qemu driver as a first step in
	making qemu work with the new network types. At this point, the
	virDomainActualNetDef is guaranteed always NULL, so the GetActualX()
	function will return exactly what the def->X that's being replaced
	would have returned (ie bisecting is not compromised).

	There is one place (in qemu_driver.c) where the internal details of
	the NetDef are directly manipulated by the code, so the GetActual
	functions cannot be used there without extra additional code; that
	file will be treated in a separate patch.

	network: separate Start/Shutdown functions for new network types
	Previously all networks were composed of bridge devices created and
	managed by libvirt, and the same operations needed to be done for all
	of them when they were started and stopped (create and start the
	bridge device, configure its MAC address and IP address, add iptables
	rules). The new network types are (for now at least) managed outside
	of libvirt, and the network object is used only to contain information
	about the network, which is then used as each individual guest
	connects itself.

	This means that when starting/stopping one of these new networks, we
	really want to do nothing, aside from marking the network as
	active/inactive.

	This has been setup as toplevel Start/Shutdown functions that do the
	small bit of common stuff, then have a switch statement to execute
	network type-specific start/shutdown code, then do a bit more common
	code. The type-specific functions called for the new host bridge and
	macvtap based types are currently empty.

	In the future these functions may actually do something, and we will
	surely add more functions that are similarly patterned. Once
	everything has settled, we can make a table of "sub-driver" function
	pointers for each network type, and store a pointer to that table in
	the network object, then we can replace the switch statements with
	calls to functions in the table.

	The final step in this will be to add a new table (and corresponding
	new functions) for new network types as they are added.

	conf: support abstracted interface info in network XML
	The network XML is updated in the following ways:

	1) The <forward> element can now contain a list of forward interfaces:

	     <forward .... >
	       <interface dev='eth10'/>
	       <interface dev='eth11'/>
	       <interface dev='eth12'/>
	       <interface dev='eth13'/>
	     </forward>

	   The first of these takes the place of the dev attribute that is
	   normally in <forward> - when defining a network you can specify
	   either one, and on output both will be present. If you specify
	   both on input, they must match.

	2) In addition to forward modes of 'nat' and 'route', these new modes
	   are supported:

	     private, passthrough, vepa - when this network is referenced by a
	     domain's interface, it will have the same effect as if the
	     interface had been defined as type='direct', e.g.:

	        <interface type='direct'>
	          <source mode='${mode}' dev='${dev}>
	          ...
	        </interface>

	     where ${mode} is one of the three new modes, and ${dev} is an interface
	     selected from the list given in <forward>.

	     bridge - if a <forward> dev (or multiple devs) is defined, and
	     forward mode is 'bridge' this is just like the modes 'private',
	     'passthrough', and 'vepa' above. If there is no forward dev
	     specified but a bridge name is given (e.g. "<bridge
	     name='br0'/>"), then guest interfaces using this network will use
	     libvirt's "host bridge" mode, equivalent to this:

	       <interface type='bridge'>
	          <source bridge='${bridge-name}'/>
	          ...
	       </interface>

	3) A network can have multiple <portgroup> elements, which may be
	   selected by the guest interface definition (by adding
	   "portgroup='${name}'" in the <source> element along with the
	   network name). Currently a portgroup can only contain a
	   virtportprofile, but the intent is that other configuration items
	   may be put there int the future (e.g. bandwidth config). When
	   building a guest's interface, if the <interface> XML itself has no
	   virtportprofile, and if the requested network has a portgroup with
	   a name matching the name given in the <interface> (or if one of the
	   network's portgroups is marked with the "default='yes'" attribute),
	   the virtportprofile from that portgroup will be used by the
	   interface.

	4) A network can have a virtportprofile defined at the top level,
	   which will be used by a guest interface when connecting in one of
	   the 'direct' modes if the guest interface XML itself hasn't
	   specified any virtportprofile, and if there are also no matching
	   portgroups on the network.

2011-07-22  Laine Stump  <laine@laine.org>

	conf: support abstracted interface info in domain interface XML
	the domain XML <interface> element is updated in the following ways:

	2) A new attribute "portgroup" has been added to the <source>
	element. When source type='network' (the only time portgroup is
	recognized), extra configuration information will be taken from the
	<portgroup> element of the given name in the network definition.

	3) Each virDomainNetDef now also potentially has a
	virDomainActualNetDef which is a private object (never
	exported/imported via the public API, and not defined in the RNG) that
	is used to maintain information about the physical device that was
	actually used for a NetDef of type VIR_DOMAIN_NET_TYPE_NETWORK.

	The virDomainActualNetDef will only be parsed/formatted if the
	parse/format function is called with the
	VIR_DOMAIN_XML_INTERNAL_ACTUAL_NET flag set (which is only needed when
	saving/loading a running domain's state info to the stateDir).

2011-07-22  Laine Stump  <laine@laine.org>

	conf: virDomainNetDef points to (rather than contains) virtPortProfile
	The virtPortProfile in the domain interface struct is now a separately
	allocated object *pointed to by* (rather than contained in) the main
	virDomainNetDef object. This is done to make it easier to figure out
	when a virtualPortProfile has/hasn't been specified in a particular
	config.

	conf: put virtPortProfile struct / functions in a common location
	virtPortProfiles are currently only used in the domain XML, but will
	soon also be used in the network XML. To prepare for that change, this
	patch moves the structure definition into util/network.h and the parse
	and format functions into util/network.c (I decided that this was a
	better choice than macvtap.h/c for something that needed to always be
	available on all platforms).

	util: define MAX
	If util.h is going to have a MIN, it may as well also have MAX.

	save: new public API to bypass file system cache on save/restore
	In order to choose whether to use O_DIRECT when saving a domain image

	command: avoid leaking fds across fork
	Since libvirt is multi-threaded, we should use FD_CLOEXEC as much
	as possible in the parent, and only relax fds to inherited after
	forking, to avoid leaking an fd created in one thread to a fork
	run in another thread.  This gets us closer to that ideal, by
	making virCommand automatically clear FD_CLOEXEC on fds intended
	for the child, as well as avoiding a window of time with non-cloexec
	pipes created for capturing output.

	rpc: Make the dispatch generator handle 'void name(void)' style procedures
	The only 'void name(void)' style procedure in the protocol is 'close' that
	is handled special, but also programming errors like a missing _args or
	_ret suffix on the structs in the .x files can create such a situation by
	accident. Making the generator aware of this avoids bogus errors from the
	generator such as:

	  Use of uninitialized value in exists at ./rpc/gendispatch.pl line 967.

	Also this allows to get rid of the -c option and the special case code for

	error: preserve errno when saving last error
	It is common to see the sequence:

	virErrorPtr save_err = virSaveLastError();
	// do cleanup
	virSetError(save_err);
	virFreeError(save_err);

	on cleanup paths.  But for functions where it is desirable to
	return the errno that caused failure, this sequence can clobber
	that errno.  virFreeError was already safe; this makes the other
	two functions in the sequence safe as well, assuming all goes
	well (on OOM, errno will be clobbered, but then again, save_err
	won't reflect the real error that happened, so you are no longer
	preserving the real situation - that's life with OOM).

	libvirt: do not mix internal flags into public API
	There were two API in driver.c that were silently masking flags
	bits prior to calling out to the drivers, and several others
	that were explicitly masking flags bits.  This is not
	forward-compatible - if we ever have that many flags in the
	future, then talking to an old server that masks out the
	flags would be indistinguishable from talking to a new server
	that can honor the flag.  In general, libvirt.c should forward
	_all_ flags on to drivers, and only the drivers should reject
	unknown flags.

	In the case of virDrvSecretGetValue, the solution is to separate
	the internal driver callback function to have two parameters
	instead of one, with only one parameter affected by the public
	API.  In the case of virDomainGetXMLDesc, it turns out that
	no one was ever mixing VIR_DOMAIN_XML_INTERNAL_STATUS with
	the dumpxml path in the first place; that internal flag was
	only used in saving and restoring state files, which happened
	to be in functions internal to a single file, so there is no

	implies a set of optional flags, where within the set you can have
	either --current or a choice of 0, 1, or both --live and --config.

	Fix now dead cleanup of VMs on libvirtd restart
	When libvirtd restarts it will attempt to reconnect to existing
	LXC containers. If it loads a XML state file for the container
	the container will appear running. If we fail to read the PID
	file, or fail to connect to the LXC monitor, we should be killing
	off the guest, but if the VMs cgroup does not exist any more,
	cleanup will get skipped. Reading the PID file is also pointless
	since the PID is in the XML statefile

	In lxcReconnectVM we do not need to read the PID file. If part
	of the reconnect process fails we need to run the VM terminate
	code as a safety net.

	In lxcVMTerminate, if we can't obtain the VM cgroup, we know
	the process has died, but we must still run lxcVMCleanup to
	clear out the virDomainObjPtr live state

	The regression is introduced by Commit da1eba6b, the new

	for condition checking.

	How to reproduce:

	% cat test.xml

	  <driver name='qemu' type='raw'/>
	  <source file='/var/lib/libvirt/images/test.img'/>

	virsh: improve option handling
	The documentation for vshCommandOptString claims that it returns
	-1 on a missing required argument, but in reality, that error
	message was unreachable (it was buried inside an if clause that

	that I decided a rewrite would make it easier to understand,
	and actually return the error values we want.

	update apparmor security driver for new udev paths
	In the Ubuntu development release we recently got a new udev that
	moves /var/run to /run, /var/lock to /run/lock and /dev/shm to /run/shm.
	This change in udev requires updating the apparmor security driver in
	libvirt[1].

	Attached is a patch that:
	 * adjusts src/security/virt-aa-helper.c to allow both
	LOCALSTATEDIR/run/libvirt/**/%s.pid and /run/libvirt/**/%s.pid. While
	the profile is not as precise, LOCALSTATEDIR/run/ is typically a symlink
	to /run/ anyway, so there is no additional access (remember that
	apparmor resolves symlinks, which is why this is still required even
	if /var/run points to /run).
	 * adjusts example/apparmor/libvirt-qemu paths for /dev/shm

	We disable some drivers when building without libvirtd in configure,
	but we do not do the same thing in libvirt.spec. It may break rpm
	building without libvirtd.

	storage: Avoid memory leak on metadata fetching
	Getting metadata on storage allocates a memory (path) which need to
	be freed after use otherwise it gets leaked. This means after use of
	virStorageFileGetMetadataFromFD or virStorageFileGetMetadata one
	must call virStorageFileFreeMetadata to free it. This function frees
	structure internals and structure itself.

	qemu: Don't overwrite errors by closefd in error paths
	When qemuMonitorCloseFileHandle is called in error path, we need to
	preserve the original error since a possible further error when running
	closefd monitor command is not very useful to users.

	qemu: Save domain status ASAP after creating qemu process
	When creating new qemu process we saved domain status XML only after the
	process was fully setup and running. In case libvirtd was killed before
	the whole process finished, once libvirtd started again it didn't know
	anything about the new process and we end up with an orphaned qemu
	process. Let's save the domain status XML as soon as we know the PID so
	that libvirtd can kill the process on restart.

	build: avoid ATTRIBUTE_UNUSED in headers
	The compiler might optimize based on our declaration that something
	is unused.  Putting that declaration in the header risks getting
	out of sync with the actual implementation, so it belongs better
	only in the .c files.  We were mostly compliant, and a new syntax
	check will help us in the future.

	* cfg.mk (sc_avoid_attribute_unused_in_header): New syntax check.
	* src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Delete
	attribute already present in .c file.
	* src/qemu/qemu_domain.h (qemuDomainEventFlush): Likewise.

	virsh: fix previous patch
	The last patch breaks make check for two reasons. First, it reverses the
	condition but leaves default level unchanged, so instead of not printing
	anything but errors before the patch it now prints all debug messages by
	default. Second, you forgot to change -d5 option passed to virsh in
	tests/virsh-optparse to -d0; the script wants to see all debug messages.

2011-07-14  Supriya Kannery  <supriyak@linux.vnet.ibm.com>

	virsh: Make "DEBUG" loglevel the superset
	Aligning loglevel values of virsh to that of libvirt.
	"DEBUG"=0 loglevel, when specified through commandline or
	env variable, should log all the messages. "ERROR=4"
	should log only error messages.

	virsh: Avoid using magic numbers for logging
	Replace magic numbers with loglevel variables.

	util: honor anchored names when searching for executables
	I got bit in a debugging session on an uninstalled libvirtd; the
	code tried to call out to the installed $LIBEXECDIR/libvirt_iohelper
	instead of my just-built version.  So I set a breakpoint and altered
	the binary name to be "./src/libvirt_iohelper", and it still failed
	because I don't have "." on my PATH.

	According to POSIX, execvp only searches PATH if the name does
	not contain a slash.  Since we are trying to mimic that behavior,
	an anchored name should be relative to the current working dir.

	This tightens existing behavior, but most callers already pass
	an absolute name or a name with no slashes, so it probably won't
	be noticeable.

	* src/util/util.c (virFindFileInPath): Anchored relative names do
	not invoke a PATH search.

	Most of the code in these two functions is supposed to be identical but
	currently it isn't (which is natural since the code is duplicated).

	qemu: Add support for job phase
	Asynchronous jobs may take long time to finish and may consist of
	several phases which we need to now about to help with recovery/rollback
	after libvirtd restarts.

	qemu: Recover from interrupted jobs
	Detect and react on situations when libvirtd was restarted or killed
	when a job was active.

	qemu: Save job type in domain status XML
	If libvirtd is restarted when a job is running, the new libvirtd process
	needs to know about that to be able to recover and rollback the
	operation.

2011-07-13  Jiri Denemark  <jdenemar@redhat.com>

	qemu: Allow all query commands to be run during long jobs
	Query commands are safe to be called during long running jobs (such as
	migration). This patch makes them all work without the need to
	special-case every single one of them.

	The patch introduces new job.asyncCond condition and associated
	job.asyncJob which are dedicated to asynchronous (from qemu monitor
	point of view) jobs that can take arbitrarily long time to finish while
	qemu monitor is still usable for other commands.

	The existing job.active (and job.cond condition) is used all other
	synchronous jobs (including the commands run during async job).

	Locking schema is changed to use these two conditions. While asyncJob is
	active, only allowed set of synchronous jobs is allowed (the set can be
	different according to a particular asyncJob) so any method that
	communicates to qemu monitor needs to check if it is allowed to be
	executed during current asyncJob (if any). Once the check passes, the
	method needs to normally acquire job.cond to ensure no other command is
	running. Since domain object lock is released during that time, asyncJob
	could have been started in the meantime so the method needs to recheck
	the first condition. Then, normal jobs set job.active and asynchronous
	jobs set job.asyncJob and optionally change the list of allowed job
	groups.

	Since asynchronous jobs only set job.asyncJob, other allowed commands
	can still be run when domain object is unlocked (when communicating to
	remote libvirtd or sleeping). To protect its own internal synchronous
	commands, the asynchronous job needs to start a special nested job
	before entering qemu monitor. The nested job doesn't check asyncJob, it
	only acquires job.cond and sets job.active to block other jobs.

	qemu: Consolidate {Enter,Exit}Monitor{,WithDriver}
	EnterMonitor and ExitMonitor methods are very similar to their

	qemu: Consolidate BeginJob{,WithDriver} into a single method
	This avoids code duplication and also avoids relying on good luck that

	Implement code to attach to external QEMU instances.
	Given a PID, the QEMU driver reads /proc/$PID/cmdline and

	into the ARGV->XML convertor to build an XML configuration
	for the process.

	/proc/$PID/exe is resolved to identify the full command
	binary path

	After checking for name/uuid uniqueness, an attempt is

	Do not drop kernel cmdline for xen pv domains
	Kernel cmdline args can be passed to xen pv domains even when a
	bootloader is specified.  The current config-to-sxpr mapping
	ignores cmdline when bootloader is present.

	Since the xend sub-driver is used with many xen toolstack versions,
	this patch takes conservative approach of adding an else block to
	existing !def->os.bootloader, and only appends sxpr if def->os.cmdline
	is non-NULL.

	If virDomainSaveConfig() failed, we will return NULL to source,
	and the vm is still available to restart during confirm() step in

	In v2 protocol, we should not set vm to NULL, because we hold

	Fix sending of reply to final RPC message
	The dispatch for the CLOSE RPC call was invoking the method
	virNetServerClientClose(). This caused the client connection
	to be immediately terminated. This meant the reply to the
	final RPC message was never sent. Prior to the RPC rewrite
	we merely flagged the connection for closing, and actually
	closed it when the next RPC call dispatch had completed.

	* daemon/remote.c: Flag connection for a delayed close
	* daemon/stream.c: Update to use new API for closing
	  failed connection
	* src/rpc/virnetserverclient.c, src/rpc/virnetserverclient.h:

2011-07-08  Daniel P. Berrange  <berrange@redhat.com>

	Fix leak of remote driver if final 'CLOSE' RPC call fails
	When closing a remote connection we issue a (fairly pointless)
	'CLOSE' RPC call to the daemon. If this fails we skip all the
	cleanup of private data, but the virConnectPtr object still
	gets released as normal. This causes a memory leak. Since the
	CLOSE RPC call is pretty pointless, just carry on freeing the
	remote driver if it fails.

	  RPC call

	Fix release of outgoing stream confirmation/abort message
	When sending back the final OK or ERROR message on completion
	of a stream, we were not decrementing the 'nrequests' tracker
	on the client. With the default requests limit of '5', this
	meant once a client had created 5 streams, they are unable to
	process any further RPC calls.  There was also a bug when
	handling an error from decoding a message length header, which
	meant a client connection would not immediately be closed.

	Fix leak of 'msg' object in client stream code
	In one exit path we forgot to free the virNetMessage object causing
	a large memory leak for streams which send a lot of data. Some other

	although this was (currently) harmless.

	* src/rpc/virnetclientstream.c: Fix leak of msg object

2011-07-08  Daniel P. Berrange  <berrange@redhat.com>

	Fix potential crash in libvirtd with active streams
	If a client disconnects while it has a stream active, there is
	a race condition which could see libvirtd crash. This is because
	the client struct may be freed before the last stream event has
	triggered. This is trivially solved by holding an extra reference
	on the client for the stream callbak

	util: Don't try to fchown files opened as non-root
	When virFileOpenAs is called with VIR_FILE_OPEN_AS_UID flag and uid/gid
	different from root/root while libvirtd is running as root, we fork a
	new child, change its effective UID/GID to uid/gid and run
	virFileOpenAsNoFork. It doesn't make any sense to fchown() the opened
	file in this case since we already know that uid/gid can access the file
	when open succeeds and one of the following situations may happen:

	- the file is already owned by uid/gid and we skip fchown even before
	  this patch
	- the file is owned by uid but not gid because it was created in a
	  directory with SETGID set, in which case it is desirable not to change
	  the group
	- the file may be owned by a completely different user and/or group
	  because it was created on a root-squashed or even all-squashed NFS
	  filesystem, in which case fchown would most likely fail anyway

	public API: prefer unsigned int for flags
	Most APIs use 'unsigned int flags'; but a few stragglers were using
	a signed value.  In particular, the vir*GetXMLDesc APIs were
	split-brain, with inconsistent choice of types.  Although it is
	an API break to use 'int' instead of 'unsigned int', it is ABI
	compatible (pre-compiled apps will have no difference in behavior),
	and generally apps can be recompiled without any issue (only rare
	apps that compiled with extremely high warning levels, or which
	pass libvirt API around as typed function pointers, would have to
	make any code changes to deal with the change).

	The migrate APIs use 'unsigned long flags', which can't be changed,
	due to ABI constraints.

	This patch intentionally touches only the public API, to prove the
	claim that most existing code (including driver callbacks and virsh)
	still compiles just fine in spite of the type change.

	* include/libvirt/libvirt.h.in (virConnectOpenAuth)
	(virDomainCoreDump, virDomainGetXMLDesc, virNetworkGetXMLDesc)
	(virNWFilterGetXMLDesc): Use unsigned int for flags.
	(virDomainHasCurrentSnapshot): Use consistent spelling.
	* src/libvirt.c (virConnectOpenAuth, virDomainCoreDump)
	(virDomainGetXMLDesc, virNetworkGetXMLDesc)
	(virNWFilterGetXMLDesc, do_open): Update accordingly.

	build: fix virBufferVasprintf on mingw
	Gnulib documents that mingw vsnprintf is broken (it returns -1
	on out-of-space, instead of the count of what would have been
	printed); but while we were using the snprintf wrapper, we had
	not yet been using the vsnprintf wrapper.

	Meanwhile, mingw (but not mingw64) has a replacement snprintf
	that fixes return values, but still lacks %1$s support; so in
	that case, gnulib didn't replace snprintf, but libintl then
	went ahead and installed a version that supported %1$s but not
	return values.  Gnulib has since been fixed to guarantee that
	the snprintf module will always guarantee the constraints needed
	by libintl.

	Also, we want to guarantee that strdup sets errno on failure.

	* .gnulib: Update to latest, for vsnprintf fix.
	* bootstrap.conf (gnulib_modules): Add vsnprintf, strdup-posix.

	Fix default value of security label 'relabel' attribute
	When no <seclabel> is present in the XML, the virDomainSeclabelDef

	domain.rng, network.rng, and interface.rng already use a few of the

	Note: POSIX doesn't guarantee the contents of fd[0] and fd[1]
	after pipe failure: http://austingroupbugs.net/view.php?id=467
	We may need to introduce a virPipe2 wrapper that guarantees
	that on pipe failure, the fds are explicitly set to -1, rather
	than our current state of assuming the fds are unchanged from
	their value prior to the failed pipe call.

	Send back an error if we get unexpected stream control message
	We ignore any stream data packets which come in for streams which
	are not registered, since these packets are async and do not have

	Fix release of virNetMessagePtr instances in streams processing

	Fix potential crash when saving guests
	The qemudDomainSaveFlag method will call EndJob on the 'vm'
	object it is passed in. This can result in the 'vm' object
	being free'd if the last reference is removed. Thus no caller
	of 'qemudDomainSaveFlag' must *ever* reference 'vm' again
	upon return.

	Unfortunately qemudDomainSave and qemuDomainManagedSave
	both call 'virDomainObjUnlock', which can result in a
	crash. This is non-deterministic since it involves a race
	with the monitor I/O thread.

	network: Don't ignore errors in dnsmasq config file creation

2011-06-29  Matthias Bolte  <matthias.bolte@googlemail.com>

	network: Fix dnsmasq hostsfile creation logic and related tests
	networkSaveDnsmasqHostsfile was added in 8fa9c2214247 (Apr 2010).
	It has a force flag. If the dnsmasq hostsfile already exists force
	needs to be true to overwrite it. networkBuildDnsmasqArgv sets force
	to false, networkDefine sets it to true. This results in the
	hostsfile being written only in networkDefine in the common case.
	If no error occurred networkSaveDnsmasqHostsfile returns true and
	networkBuildDnsmasqArgv adds the --dhcp-hostsfile to the dnsmasq
	command line.

	networkSaveDnsmasqHostsfile was changed in 89ae9849f744 (24 Jun 2011)
	to return a new dnsmasqContext instead of reusing one. This change broke
	the logic of the force flag as now networkSaveDnsmasqHostsfile returns
	NULL on error, but the early return -- if force was not set and the
	hostsfile exists -- returns 0. This turned the early return in an error
	case and networkBuildDnsmasqArgv didn't add the --dhcp-hostsfile option
	anymore if the hostsfile already exists. It did because networkDefine
	created the hostsfile already.

	Then 9d4e2845d498 fixed the return 0 case in networkSaveDnsmasqHostsfile
	but didn't apply the force option correctly to the new addnhosts file.
	Now force doesn't control an early return anymore, but influences the
	handling of the hostsfile context creation and dnsmasqSave is always
	called now. This commit also added test cases that reveal several
	problems. First, the tests now calls functions that try to write the
	dnsmasq config files to disk. If someone runs this tests as root this
	might overwrite actively used dnsmasq config files, this is a no-go. Also
	the tests depend on configure --localstatedir, this needs to be fixed as
	well, because it makes the tests fail when localstatedir is different
	from /var.

	This patch does several things to fix this:

	1) Move dnsmasqContext creation and saving out of networkBuildDnsmasqArgv
	to the caller to separate the command line generation from the config
	file writing. This makes the command line generation testable without the
	risk of interfering with system files, because the tests just don't call
	dnsmasqSave.

	2) This refactoring of networkSaveDnsmasqHostsfile makes the force flag
	useless as the saving happens somewhere else now. This fixes the wrong
	usage of the force flag in combination with then newly added addnhosts
	file by removing the force flag.

	3) Adapt the wrong test cases to the correct behavior, by adding the
	missing --dhcp-hostsfile option. Both affected tests contain DHCP host
	elements but missed the necessary --dhcp-hostsfile option.

	4) Rename networkSaveDnsmasqHostsfile to networkBuildDnsmasqHostsfile,
	because it doesn't save the dnsmasqContext anymore.

	5) Move all directory creations in dnsmasq context handling code from
	the *New functions to dnsmasqSave to avoid directory creations in system
	paths in the test cases.

	6) Now that networkBuildDnsmasqArgv doesn't create the dnsmasqContext
	anymore the test case can create one with the localstatedir that is
	expected by the tests instead of the configure --localstatedir given one.

	Fix compilation with systemtap 1.3
	Version 1.3 of <sys/sdt.h> uses this macro

	that breaks like this if t is a function

	  remote.c:1775: error: cast from function call of type 'const char *'
	  to non-matching type 'long unsigned int' [-Wbad-function-cast]

	For that to work it should probably look like this

	  #define STAP_CAST(t) ((size_t)(t))

	In systemtap 1.4 this was completely rewritten.

	Anyway, before commit df0b57a95a767c t was always a variable, but now
	also a function is used here, namely virNetSASLSessionGetIdentity.

	Support automatic creation of leases for disks in sanlock
	The current sanlock plugin requires a central management
	application to manually add <lease> elements to each guest,
	to protect resources that are assigned to it (eg writable
	disks). This makes the sanlock plugin useless for usage
	in more ad hoc deployment environments where there is no
	central authority to associate disks with leases.

	This patch adds a mode where the sanlock plugin will
	automatically create leases for each assigned read-write
	disk, using a md5 checksum of the fully qualified disk
	path. This can work pretty well if guests are using
	stable disk paths for block devices eg /dev/disk/by-path/XXXX
	symlinks, or if all hosts have NFS volumes mounted in
	a consistent pattern.

	The plugin will create one lockspace for managing disks
	with filename /var/lib/libvirt/sanlock/__LIBVIRT__DISKS__.
	For each VM disks, there will be another file to hold
	a lease /var/lib/libvirt/sanlock/5903e5d25e087e60a20fe4566fab41fd
	Each VM disk lease is usually 1 MB in size. The script
	virt-sanlock-cleanup should be run periodically to remove
	unused lease files from the lockspace directory.

	To make use of this capability the admin will need to do
	several tasks:

	 - Mount an NFS volume (or other shared filesystem)
	   on /var/lib/libvirt/sanlock
	 - Configure 'host_id' in /etc/libvirt/qemu-sanlock.conf
	   with a unique value for each host with the same NFS
	   mount
	 - Toggle the 'auto_disk_leases' parameter in qemu-sanlock.conf

	Technically the first step can be skipped, in which case
	sanlock will only protect against 2 vms on the same host
	using the same disk (or the same VM being started twice
	due to error by libvirt).

	network: add domain to unqualified names defined with <host>
	If a domain name is defined for a network, add the --expand-hosts
	option to the dnsmasq commandline. This results in the domain being
	added to any hostname that is defined in a dns <host> element and
	contains no '.' characters (i.e. it is an "unqualified"
	hostname). Since PTR records are automatically created for any name
	defined in <host>, the result of a PTR request will change from the
	unqualified name to the qualified name.

	This also has the same effect on any hostnames that dnsmasq reads
	from the host's /etc/hosts file.

	(In the case of guest hostnames that were learned by dnsmasq via DHCP
	requests, they were already getting the domain name added on, even
	without --expand-hosts).

	Ensure sanlock socket is labelled with the VM process label
	The libvirt sanlock plugin is intentionally leaking a file
	descriptor to QEMU. To enable QEMU to use this FD under
	SELinux, it must be labelled correctly. We dont want to use
	the svirt_image_t for this, since QEMU must not be allowed
	to actually use the FD. So instead we label it with svirt_t

	vcpupin: add query option to virsh vcpupin command
	This patch teaches "virsh vcpupin" command to query if no list
	is given. Its feature is to show CPU affinity information in more
	reader-friendly way.

	 # virsh vcpupin VM --config
	 VCPU: CPU Affinity
	 ----------------------------------
	    0: 1-6,9-20
	    1: 10
	    2: 5,9-11,15-20
	    3: 1,3,5,7,9,11,13,15

	When cpulist is omitted, vcpu number is optional. When vcpu number is
	provided, information of only specified vcpu is displayed.

	vcpuinfo: add the code to fallback to try new API
	The "virsh vcpuinfo" command results in failure when the target domain

	virDomainGetVcpus API returns error and the target domain is inactive.

	vcpupin: implement the code to support new API for the qemu driver

	vcpupin: introduce the new libvirt API (virDomainGetVcpupinInfo)
	This patch introduces a new libvirt API (virDomainGetVcpupinInfo),
	as a counterpart to virDomainPinVcpuFlags.

	We can use virDomainGetVcpus API to retrieve CPU affinity information,
	but can't use this API against inactive domains (at least in case of KVM),
	as it lacks a flags parameter.
	The usual thing is to add a new virDomainGetVcpusFlags, but that API name
	is already occupied by the counterpart to virDomainGetMaxVcpus, which
	has a completely different signature.

	The virDomainGetVcpupinInfo is the new API to retrieve CPU affinity
	information of active and inactive domains.  While the usual convention
	is to list an array before its length, this API violates that rule
	in order to be more like virDomainGetVcpus (where maxinfo was doing
	double-duty as the length of two different arrays).

	Move load of AppArmor profile to GenLabel()
	Commit 12317957ecd6c37a2fb16275dcdeeacfe25c517 introduced an incompatible
	architectural change for the AppArmor security driver. Specifically,
	virSecurityManagerSetAllLabel() is now called much later in
	src/qemu/qemu_process.c:qemuProcessStart(). Previously, SetAllLabel() was
	called immediately after GenLabel() such that after the dynamic label (profile
	name) was generated, SetAllLabel() would be called to create and load the
	AppArmor profile into the kernel before qemuProcessHook() was executed. With
	12317957ecd6c37a2fb16275dcdeeacfe25c517, qemuProcessHook() is now called
	before SetAllLabel(), such that aa_change_profile() ends up being called
	before the AppArmor profile is loaded into the kernel (via ProcessLabel() in
	qemuProcessHook()).

	This patch addresses the change by making GenLabel() load the AppArmor
	profile into the kernel after the label (profile name) is generated.
	SetAllLabel() is then adjusted to only reload_profile() and append stdin_fn to
	the profile when it is specified. This also makes the AppArmor driver work
	like its SELinux counterpart with regard to SetAllLabel() and stdin_fn.

	Allow automatic kill of guests when a connection is closed
	If an application is using libvirt + KVM as a piece of its
	internal infrastructure to perform a specific task, it can
	be desirable to guarentee the VM dies when the virConnectPtr
	disconnects from libvirtd. This ensures the app can't leak
	any VMs it was using. Adding VIR_DOMAIN_START_AUTOKILL as
	a flag when starting guests enables this to be done.

	Automatically kill target QEMU if migration aborts abnormally
	Migration is a multi-step process

	  1. Begin(src)
	  2. Prepare(dst)
	  3. Perform(src)
	  4. Finish(dst)
	  5. Confirm(src)

	At step 2, a QEMU process is lauched in the destination to
	accept the incoming migration. Occasionally the process
	that is controlling the migration workflow aborts, and fails
	to call step 4, Finish. This leaves a QEMU process running
	on the target (albeit with paused CPUs). Unfortunately because
	step 2 actives a job on the QEMU process, it is unkillable by
	normal means.

	By registering the VM for autokill against the src virConnectPtr
	in step 2, we can ensure that the guest is forcefully killed off
	if the connection is closed without step 4 being invoked

	* src/qemu/qemu_migration.c: Register autokill in PrepareDirect
	  and PrepareTunnel. Unregister autokill on successful run

	a connection is closed. For example, kill an incoming migration if
	the client managing the migration dies. This introduces a map between
	guest 'uuid' strings and virConnectPtr objects. When a connection is
	closed, any associated guests are killed off.

	* src/qemu/qemu_conf.h: Add autokill hash table to qemu driver
	* src/qemu/qemu_process.c, src/qemu/qemu_process.h: Add APIs
	  for performing autokill of guests associated with a connection
	* src/qemu/qemu_driver.c: Initialize autodestroy map

	Support reboots with the QEMU driver
	For controlled shutdown we issue a 'system_powerdown' command
	to the QEMU monitor. This triggers an ACPI event which (most)
	guest OS wire up to a controlled shutdown. There is no equiv
	ACPI event to trigger a controlled reboot. This patch attempts
	to fake a reboot.

	 - In qemuDomainObjPrivatePtr we have a bool fakeReboot
	   flag.
	 - The virDomainReboot method sets this flag and then
	   triggers a normal 'system_powerdown'.
	 - The QEMU process is started with '-no-shutdown'
	   so that the guest CPUs pause when it powers off the
	   guest
	 - When we receive the 'POWEROFF' event from QEMU JSON
	   monitor if fakeReboot is not set we invoke the
	   qemuProcessKill command and shutdown continues
	   normally
	 - If fakeReboot was set, we spawn a background thread
	   which issues 'system_reset' to perform a warm reboot
	   of the guest hardware. Then it issues 'cont' to
	   start the CPUs again

	* src/qemu/qemu_command.c: Add -no-shutdown flag if
	  we have JSON support
	* src/qemu/qemu_domain.h: Add 'fakeReboot' flag to
	  qemuDomainObjPrivate struct
	* src/qemu/qemu_driver.c: Fake reboot using the
	  system_powerdown command if JSON support is available
	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
	  src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h,

	  binding for system_reset command
	* src/qemu/qemu_process.c: Reset the guest & start CPUs if
	  fakeReboot is set

	Introduce generic RPC client objects
	To facilitate creation of new clients using XDR RPC services,
	pull alot of the remote driver code into a set of reusable
	objects.

	 - virNetClient: Encapsulates a socket connection to a
	   remote RPC server. Handles all the network I/O for
	   reading/writing RPC messages. Delegates RPC encoding
	   and decoding to the registered programs

	 - virNetClientProgram: Handles processing and dispatch
	   of RPC messages for a single RPC (program,version).
	   A program can register to receive async events
	   from a client

	 - virNetClientStream: Handles generic I/O stream
	   integration to RPC layer

	Each new client program now merely needs to define the list of
	RPC procedures & events it wants and their handlers. It does
	not need to deal with any of the network I/O functionality at
	all.

	Introduce generic RPC server objects
	To facilitate creation of new daemons providing XDR RPC services,
	pull a lot of the libvirtd daemon code into a set of reusable
	objects.

	 * virNetServer: A server contains one or more services which
	   accept incoming clients. It maintains the list of active
	   clients. It has a list of RPC programs which can be used
	   by clients. When clients produce a complete RPC message,
	   the server passes this onto the corresponding program for
	   handling, and queues any response back with the client.

	 * virNetServerClient: Encapsulates a single client connection.
	   All I/O for the client is handled, reading & writing RPC
	   messages.

	 * virNetServerProgram: Handles processing and dispatch of
	   RPC method calls for a single RPC (program,version).
	   Multiple programs can be registered with the server.

	 * virNetServerService: Encapsulates socket(s) listening for
	   new connections. Each service listens on a single host/port,
	   but may have multiple sockets if on a dual IPv4/6 host.

	Each new daemon now merely has to define the list of RPC procedures
	& their handlers. It does not need to deal with any network related
	functionality at all.

	Integrate TLS/SASL directly into the socket APIs
	This extends the basic virNetSocket APIs to allow them to have
	a handle to the TLS/SASL session objects, once established.
	This ensures that any data reads/writes are automagically
	passed through the TLS/SASL encryption layers if required.

	* src/rpc/virnetsocket.c, src/rpc/virnetsocket.h: Wire up

	   data encryption/decryption once the session is established

	* src/Makefile.am: Add to libvirt-net-rpc.la
	* src/rpc/virnetsaslcontext.c, src/rpc/virnetsaslcontext.h: Generic

	Provide a simple object for encoding/decoding RPC messages
	This provides a new struct that contains a buffer for the RPC
	message header+payload, as well as a decoded copy of the message
	header. There is an API for applying a XDR encoding & decoding
	of the message headers and payloads. There are also APIs for
	maintaining a simple FIFO queue of message instances.

	Expected usage scenarios are:

	To send a message

	   msg = virNetMessageNew()

	   ...fill in msg->header fields..
	   virNetMessageEncodeHeader(msg)
	   ...loook at msg->header fields to determine payload filter
	   virNetMessageEncodePayload(msg, xdrfilter, data)
	   ...send msg->bufferLength worth of data from buffer

	To receive a message

	   msg = virNetMessageNew()
	   ...read VIR_NET_MESSAGE_LEN_MAX of data into buffer
	   virNetMessageDecodeLength(msg)
	   ...read msg->bufferLength-msg->bufferOffset of data into buffer
	   virNetMessageDecodeHeader(msg)
	   ...look at msg->header fields to determine payload filter
	   virNetMessageDecodePayload(msg, xdrfilter, data)
	   ...run payload processor

	* src/Makefile.am: Add to libvirt-net-rpc.la
	* src/rpc/virnetmessage.c, src/rpc/virnetmessage.h: Internal
	  message handling API.
	* testutils.c, testutils.h: Helper for printing binary differences

	Defines the basics of a generic RPC protocol in XDR
	This patch defines the basics of a generic RPC protocol in XDR.
	This is wire ABI compatible with the original remote_protocol.x.
	It takes everything except for the RPC calls / events from that
	protocol

	 - The basic header virNetMessageHeader (aka remote_message_header)
	 - The error object virNetMessageError  (aka remote_error)
	 - Two dummy objects virNetMessageDomain & virNetMessageNetwork
	   sadly needed to keep virNetMessageError ABI compatible with
	   the old remote_error

	The RPC protocol supports method calls, async events and
	bidirectional data streams as before

	* src/Makefile.am: Add rules for generating RPC code from

	python: events: Fix C->Python handle callback prototype
	If registering our own event loop implementation written in python,

	Problem is, the current setup requires the user's event loop to know
	about this trickery, rather than just treating the opaque value

	requires the handler to return the string data to send rather than
	store the data in a string pointer.

	python: Implement virStreamSend/Recv
	The return values for the python version are different that the C version
	of virStreamSend: on success we return a string, an error raises an exception,
	and if the stream would block we return int(-2). We need to do this

	Fix compile warnings in virsh vcpupin
	The 'char *cur' variable was being assigned from a
	'const char *' string, thus discarding constness.
	As well as causing a compile warning, it masked a
	piece of code which attempts to assign to the
	previously const string.

	vcpupin: add vcpupin resetting feature to qemu driver
	Pinning to all physical cpus means resetting, hence it is preferable to
	delete vcpupin setting of XML.

	This patch changes qemu driver to delete vcpupin setting by invoking
	virDomainVcpupinDel API when pinning the specified virtual cpu to
	all host physical cpus.

2011-06-20  Taku Izumi  <izumi.taku@jp.fujitsu.com>

	vcpupin: add virDomainVcpupinDel function
	This patch add the private API (virDomainVcpupinDel).
	This API can delete the vcpupin setting of a specified virtual cpu.

2011-06-20  Taku Izumi  <izumi.taku@jp.fujitsu.com>

	vcpupin: add reset option to virsh vcpupin command
	When resetting vcpupin setting, we have to specify all host physical
	cpus as a cpulist parameter of virsh vcpupin command. It's a little
	tedious.

	This patch changes to allow to receive the special keyword 'r' as a cpulist
	parameter of virsh vcpupin command when resetting vcpupin setting.

	If you set the following:

	 # virsh vcpupin VM 0 r

	the vcpu0 will be pinned to all physical cpus.

2011-06-20  Taku Izumi  <izumi.taku@jp.fujitsu.com>

	vcpupin: improve vcpupin definition of virsh vcpupin
	When using vcpupin command, we have to speficy comma-separated list as cpulist,
	but this is tedious in case the number of phsycal cpus is large.
	This patch improves this by introducing special markup "-" and "^" which are
	similar to XML schema of "cpuset" attribute.

	The example:

	 # virsh vcpupin Guest 0 0-15,^8

	 is identical to

	 # virsh vcpupin Guest 0 0,1,2,3,4,5,6,7,9,10,11,12,13,14,15

	NOTE: The expression is sequentially evaluated, so "0-15,^8" is not identical
	to "^8,0-15".

	numatune: Add tests for numatune XML
	Only add tests for qemuxmlargvtest.c, as there is no qemu command line

2011-06-20  Osier Yang  <jyang@redhat.com>

	numatune: Support NUMA memory tuning in qemu driver
	Implemented as setting NUMA policy between fork and exec as a hook,
	using libnuma. Only support memory tuning on domain process currently.

	For the nodemask out of range, will report soft warning instead of
	hard error in libvirt layer. (Kernel will be silent as long as one
	of set bit in the nodemask is valid on the host. E.g. For a host
	has two NUMA nodes, kernel will be silent for nodemask "01010101").
	So, soft warning is the only thing libvirt can do, as one might want
	to specify the numa policy prior to a node that doesn't exist yet,
	however, it may come as hotplug soon.

	build: fix building error when building without libvirtd
	When building libvirt without libvirtd, we will receive the following error
	message:

	make[3]: Entering directory `/home/wency/rpmbuild/BUILD/libvirt-0.9.2/tools'
	  CC     virsh-virsh.o
	  CC     virsh-console.o

	./src/.libs/libvirt.so: undefined reference to `numa_available'
	./src/.libs/libvirt.so: undefined reference to `numa_max_node'
	collect2: ld returned 1 exit status

	The reason is that: we check numactl only when building qemu driver, and qemu
	driver will not be built when bulding without libvirtd. So with_numactl's
	value is check and we will not link libnuma.so.

	In the other function, we call numa_available() and numa_max_node() only
	when HAVE_NUMACTL is 1. We should do the same check in the function nodeGetMemoryStats().

	apparmor: implement AppArmorSetFDLabel()
	During a savevm operation, libvirt will now use fd migration if qemu
	supports it. When the AppArmor driver is enabled, AppArmorSetFDLabel()
	is used but since this function simply returns '0', the dynamic AppArmor
	profile is not updated and AppArmor blocks access to the save file. This
	patch implements AppArmorSetFDLabel() to get the pathname of the file by
	resolving the fd symlink in /proc, and then gives that pathname to
	reload_profile(), which fixes 'virsh save' when AppArmor is enabled.

	command: avoid double close
	Previously, the parent process opened 'null' to /dev/null, then
	the child process closes 'null' as well as 'childout'.  But if
	childout was set to be null, then this is a double close.  At
	least the double close was confined to the child process after a
	fork, and therefore there is no risk of another thread opening
	an fd of the same value to be bitten by the double close, but it
	is always better to avoid double-close to begin with.

	Additionally, if all three fds were specified, then opening
	'null' was wasted.

	This patch fixes things to lazily open null on the first use,
	then guarantees it gets closed exactly once.

	we should support parsing "actual".

	Fix dlopen dependency
	Since the addition of the lock manager framework in 6a943419c528fdd7
	dlopen is always required, but the checks in configure wasn't changed
	to reflect that. This didn't show up directly because the VirtualBox
	driver linking dlopen in covered it. But disabling the VirtualBox
	driver makes the build fail due to missing dlopen.

	Change the dlopen check in configure to pick up dlopen when available.

	tests: add a test for multi function PCI device

2011-06-13  Wen Congyang  <wency@cn.fujitsu.com>

	support multifunction PCI device
	If qemu supports multi function PCI device, the format of the PCI address passed
	to qemu is "bus=pci.0,multifunction=on,addr=slot.function".

	If qemu does not support multi function PCI device, the format of the PCI address
	passed to qemu is "bus=pci.0,addr=slot".

2011-06-13  Wen Congyang  <wency@cn.fujitsu.com>

	the hotplugged PCI device should use the whole slot
	Hot pluging/unpluging multi PCI device is not supported now. So the function
	of hotplugged PCI device must be 0. When we hot unplug it, we should set release
	all functions in the slot.

	assign the whole slot to the PCI device that has no address
	If user does not specify the PCI address, we should auto assign an unused slot.

	Reimplement qemuDomainPCIAddressReserveSlot(): reserve all functions in the slot
	We will support multi function PCI device. So we should reserve all functions in
	the slot if we want to reserve a slot.

	the key of hash table should include the function value
	We save all used PCI address in the hash table. The key is generated by domain,
	bus and slot now. We will support multi function PCI device, so the key should
	be generated by domain, bus, slot and function.

	prevent hot unplugging multi function PCI device
	We do not support to hot unplug multi function PCI device now. If the device is
	one function of multi function PCI device, we shoul not allow to hot unplugg
	it.

	check whether qemu supports multi function PCI device
	qemu supports multi function PCI device at least version 0.13.0.

	esx: avoid dead code
	Detected by Coverity.  The beginning of the function already filtered
	out NULL objectContentList as invalid.  Further investigation shows:

	esxVI_RetrieveProperties is generated and returns a list of objects
	that match the given propertyFilterSpec.
	esxVI_LookupObjectContentByType then tests whether the result
	corresponds to the expected occurrence and reports an error otherwise.
	This simplifies the callers of  esxVI_LookupObjectContentByType, but
	due to the missing dereference the check was never performed because
	the code thought that at least one item was obtained. NULL represents
	an empty list. This is a potential segfault fix because callers of
	esxVI_LookupObjectContentByType that specified "required" occurrence
	assume *objectContentList to be non-NULL when
	esxVI_LookupObjectContentByType succeeds.

	debug: avoid null dereference on uuid lookup api
	Detected by Coverity.  Commit a98d8f0d tried to make uuid debugging
	more robust, but missed some APIs.  And on the APIs that it visited,
	the mere act of preparing the debug message ends up dereferencing
	uuid prior to the null check.  Which means the APIs which are supposed
	to gracefully reject NULL arguments now end up with SIGSEGV.

	* src/libvirt.c (VIR_UUID_DEBUG): New macro.
	(virDomainLookupByUUID, virDomainLookupByUUIDString)

	python: avoid unlikely sign extension bug
	Detected by Coverity.  cpumap was allocated with a value of
	(unsigned short)*(int), which is an int computation, and then
	promotes to size_t.  On a 64-bit platform, this fails if bit
	32 of the product is set (because of sign extension giving
	a HUGE value to malloc), even though a naive programmer would
	assume that since the first value is unsigned, the product
	is also unsigned and at most 4GB would be allocated.

	Won't bite in practice (the product should never be that large),
	but worth using the right types to begin with, so that we are
	now computing (unsigned short)*(size_t).

	* python/libvirt-override.c (libvirt_virDomainGetVcpus): Use
	correct type.

2011-06-08  Eric Blake  <eblake@redhat.com>

	storage: avoid mishandling backing store > 2GB
	Detected by Coverity.  The code was doing math on shifted unsigned
	char (which promotes to int), then promoting that to unsigned long
	during assignment to size.  On 64-bit platforms, this risks sign
	extending values of size > 2GiB.  Bug present since commit
	489fd3 (v0.6.0).

	I'm not sure if a specially-crafted bogus qcow2 image could
	exploit this, although it's probably not possible, since we
	were already checking for the computed results being within
	range of our fixed-size buffer.

	* src/util/storage_file.c (qcowXGetBackingStore): Avoid sign
	extension.

	lxc: Improve guest startup error reporting
	Add a simple handshake with the lxc_controller process so we can detect

	Arranges things similar to the qemu driver. Will allow us to more easily

	Avoid virGetVersion failure on specific driver support configurations
	virGetVersion itself doesn't take a virConnectPtr, but in order to obtain
	the hypervisor version against which libvirt was compiled it is used in
	combination with virConnectGetType like this:

	hvType = virConnectGetType(conn)
	virGetVersion(&libVer, hvType, &typeVer)

	When virConnectGetType is called on a remote connection then the remote
	driver returns the type of the underlying driver on the server side, for
	example QEMU. Then virGetVersion compares hvType to a set of strings that
	depend on configure options and returns LIBVIR_VERSION_NUMBER in most
	cases. Now this fails in case libvirt on the client side is just compiled
	with the remote driver enabled only and the server side has the actual
	driver such as the QEMU driver. It just happens to work when the actual
	driver is enabled on client and server side. But that's not always true.
	I noticed this on FreeBSD:

	freebsd# virsh -c qemu+tcp://192.168.178.22/system version
	Compiled against library: libvir 0.9.2
	error: failed to get the library version
	error: this function is not supported by the connection driver: virGetVersion

	This is not FreeBSD specific, happens on Windows as well due to the
	similar driver support configuration. The problem is that virConnectGetType
	returns QEMU, but virGetVersion on the client side only accepts Remote
	as hvType due to all other drivers being disabled on the client side.

	Daniel P. Berrange suggested to get rid of all the conditional code in
	virGetVersion, ignoring the hvType and always setting typeVer to
	LIBVIR_VERSION_NUMBER. virConnectGetVersion is supposed to be used to
	obtain the hypervisor version.

	security driver: ignore EINVAL when chowning an image file
	This fixes:

	  https://bugzilla.redhat.com/show_bug.cgi?id=702044
	  https://bugzilla.redhat.com/show_bug.cgi?id=709454

	Both of these complain of a failure to use an image file that resides
	on a read-only NFS volume. The function in the DAC security driver
	that chowns image files to the qemu user:group before using them
	already has special cases to ignore failure of chown on read-only file
	systems, and in a few other cases, but it hadn't been checking for
	EINVAL, which is what is returned if the qemu user doesn't even exist
	on the NFS server.

	Since the explanation of EINVAL in the chown man page almost exactly
	matches the log message already present for the case of EOPNOTSUPP,

	Explicitly set VM state to paused after migration completes
	In v3 migration, once migration is completed, the VM needs
	to be left in a paused state until after Finish3 has been
	executed on the target. Only then will the VM be killed
	off. When using non-JSON QEMU monitor though, we don't
	receive any 'STOP' event from QEMU, so we need to manually
	set our state offline & thus release lock manager leases.
	It doesn't hurt to run this on the JSON case too, just in
	case the event gets lost somehow

	Fix handling of VIR_EVENT_HANDLE_ERROR in QEMU monitor
	Commit 4454a9efc728b91e791b1f14c26ea23a19d57f48 introduced bad
	behaviour on the VIR_EVENT_HANDLE_ERROR condition. This condition
	is only hit when an invalid FD is used in poll() (typically due
	to a double-close bug). The QEMU monitor code was treating this
	condition as non-fatal, and thus libvirt would poll() in a fast
	loop forever burning 100% CPU. VIR_EVENT_HANDLE_ERROR must be
	handled in the same way as VIR_EVENT_HANDLE_HANGUP, killing the
	QEMU instance.

	Add call to sanlock_restrict() in QEMU lock driver
	In between fork and exec, a connection to sanlock is acquired

	Support passing QEMU lock state to dest during migration
	Some lock managers associate state with leases, allowing a process
	to temporarily release its leases, and re-acquire them later, safe
	in the knowledge that no other process has acquired + released the
	leases in between.

	This is already used between suspend/resume operations, and must
	also be used across migration. This passes the lockstate in the
	migration cookie. If the lock manager uses lockstate, then it
	becomes compulsory to use the migration v3 protocol to get the
	cookie support.

	Integrate the QEMU driver with the lock manager infrastructure
	The QEMU integrates with the lock manager instructure in a number
	of key places

	 * During startup, a lock is acquired in between the fork & exec
	 * During startup, the libvirtd process acquires a lock before
	   setting file labelling
	 * During shutdown, the libvirtd process acquires a lock
	   before restoring file labelling
	 * During hotplug, unplug & media change the libvirtd process
	   holds a lock while setting/restoring labels

	The main content lock is only ever held by the QEMU child process,
	or libvirtd during VM shutdown. The rest of the operations only
	require libvirtd to hold the metadata locks, relying on the active
	QEMU still holding the content lock.

	Support leases in guest XML and lock manager
	A lock manager may operate in various modes. The direct mode of
	operation is to obtain locks based on the resources associated
	with devices in the XML. The indirect mode is where the app
	creating the domain provides explicit leases for each resource
	that needs to be locked. This XML extension allows for listing
	resources in the XML

	  <devices>
	     ...
	     <lease>
	       <lockspace>somearea</lockspace>
	       <key>thequickbrownfoxjumpsoverthelazydog</key>
	       <target path='/some/lease/path' offset='23432'/>
	     </lease>
	     ...
	  </devices>

	The 'lockspace' is a unique identifier for the lockspace which
	the lease is associated

	The 'key' is a unique identifier for the resource associated
	with the lease.

	The 'target' is the file on disk where the leases are held.

	Allow handshake with child process during startup
	Allow the parent process to perform a bi-directional handshake
	with the child process during fork/exec. The child process
	will fork and do its initial setup. Immediately prior to the
	exec(), it will stop & wait for a handshake from the parent
	process. The parent process will spawn the child and wait
	until the child reaches the handshake point. It will do
	whatever extra setup work is required, before signalling the
	child to continue.

	The implementation of this is done using two pairs of blocking
	pipes. The first pair is used to block the parent, until the
	child writes a single byte. Then the second pair pair is used
	to block the child, until the parent confirms with another
	single byte.

	Allow custom XML to be passed in during migration
	Update the qemuDomainMigrateBegin method so that it accepts
	an optional incoming XML document. This will be validated
	for ABI compatibility against the current domain config,
	and if this check passes, will be passed back out for use
	by the qemuDomainMigratePrepare method on the target

2011-05-31  Daniel P. Berrange  <berrange@redhat.com>

	Allow virsh to pass in a custom XML document for migration
	Switch virsh migrate over to use virDomainMigrate2 and
	virDomainMigrateToURI2. This is still compatible with
	older libvirts, because these methods dynamically choose
	whether to perform v1, v2 or v3 migration based on declared
	RPC support from the libvirtd instances

	Add a --xml arg which allows the user to pass in a custom
	XML document. This XML document must be ABI compatible
	with the current *live* XML document for the running guest
	on the source host. ABI compatibility will be enforced by
	any driver supporting this function

	lxc: Seperate domain config loading
	This patch seperate the domain config loading just as qemu driver

	saying can't connect to domain monitor.

	Issue full error messages when processing QEMU monitor I/O
	Currently the QEMU monitor I/O handler code uses errno values
	to report errors. This results in a sub-optimal error messages
	on certain conditions, in particular when parsing JSON strings
	malformed data simply results in 'EINVAL'.

	This changes the code to use the standard libvirt error reporting
	APIs. The virError is stored against the qemuMonitorPtr struct,
	and when a monitor API is run, any existing stored error is copied
	into that thread's error local

	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
	  src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_text.c: Use

2011-05-29  Daniel P. Berrange  <berrange@redhat.com>

	Don't kill QEMU process when a monitor I/O parsing error occurs
	Currently whenever there is any failure with parsing the monitor,
	this is treated in the same was as end-of-file (ie QEMU quit).
	The domain is terminated, if not already dead.

	With this change, failures in parsing the monitor stream do not
	result in the death of QEMU. The guest continues running unchanged,
	but all further use of the monitor will be disabled.

	The VMM_FAILURE event will be emitted, and the mgmt application
	can decide when to kill/restart the guest to re-gain control

	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Run a
	  different callback for monitor EOF vs error conditions.
	* src/qemu/qemu_process.c: Emit VMM_FAILURE event when monitor
	  fails

2011-05-29  Daniel P. Berrange  <berrange@redhat.com>

	Introduce a new event emitted when a virtualization failure occurs
	This introduces a new domain

	  VIR_DOMAIN_EVENT_ID_CONTROL_ERROR

	Which uses the existing generic callback

	typedef void (*virConnectDomainEventGenericCallback)(virConnectPtr conn,
	                                                     virDomainPtr dom,
	                                                     void *opaque);

	This event is intended to be emitted when there is a failure in
	some part of the domain virtualization system. Whether the domain
	continues to run/exist after the failure is an implementation
	detail specific to the hypervisor.

	The idea is that with some types of failure, hypervisors may
	prefer to leave the domain running in a "degraded" mode of
	operation. For example, if something goes wrong with the QEMU
	monitor, it is possible to leave the guest OS running quite
	happily. The mgmt app will simply loose the ability todo various
	tasks. The mgmt app can then choose how/when to deal with the
	failure that occured.

	interface: define internal driver API for network config transactions

2011-05-28  Michal Privoznik  <mprivozn@redhat.com>

	interface: new public API for network config change transactions
	This is the API agreed on in:

	  https://www.redhat.com/archives/libvir-list/2011-May/msg00026.html

	(with a slight name change to use "...begin" rather than
	"...start"). This implements transactional changes to the host network
	config. When a transaction is begun with ncf_change_begin(), all other
	netcf APIs will continue to work as they always have, but a snapshot
	of the existing config will be taken, allowing reversion (rollback,
	using ncf_change_rollback()) to the exact state of config at the time
	ncf_change_begin() was called. Alternately, if it's determined that
	the new changes are acceptable, ncf_change_commit() can be called,
	which will eliminate the snapshot and make the changes permanent.

	As a failsafe measure, if neither ncf_change_commit() or
	ncf_change_rollback() is called by the next time the system reboots,
	the netcf-transaction initscript will be automatically called to
	rollback the changes.

	In most cases this affects flags parameters that are unsigned in the
	public and driver API but signed in the XDR protocol. Switch the
	XDR protocol to unsigned for those.

	A counterexample is virNWFilterGetXMLDesc. Its flags parameter is signed
	in the public API and XDR protocol, but unsigned in the driver API.

	remote generator: Fix XDR sign mismatch for virNodeGet(Cells)FreeMemory
	virNodeGetFreeMemory used unsigned long long in the public API but
	signed hyper in the XDR protocol. Convert the XDR protocol to use
	unsigned hyper.

	As explained by Eric before, this doesn't affect the on-the-wire protocol.

	remote generator: Make call-by-reference handling stricter
	Several functions return values by reference parameters. This is realized
	by passing the members of remote_CALL_ret by reference to the called
	function.

	The position of this parameters in the function signature follows some
	patterns with some exceptions. This patterns and exceptions are hardcoded
	in the generator.

	Add an insert@<offset> annotation to the remote_CALL_ret struct members
	for functions that return lists to remove some of the hardcoded patterns
	and exceptions.

	Fix the signature of virDomainMigrateFinish3 for error reporting
	The current virDomainMigrateFinish3 method signature attempts to
	distinguish two types of errors, by allowing return with ret== 0,
	but ddomain == NULL, to indicate a failure to start the guest.
	This is flawed, because when ret == 0, there is no way for the
	virErrorPtr details to be sent back to the client.

	Change the signature of virDomainMigrateFinish3 so it simply
	returns a virDomainPtr, in the same way as virDomainMigrateFinish2
	The disk locking code will protect against the only possible
	failure mode this doesn't account for (loosing conenctivity to
	libvirtd after Finish3 starts the CPUs, but before the client
	sees the reply for Finish3).

	* src/driver.h, src/libvirt.c, src/libvirt_internal.h: Change
	  virDomainMigrateFinish3 to return a virDomainPtr instead of int
	* src/remote/remote_driver.c, src/remote/remote_protocol.x,
	  daemon/remote.c, src/qemu/qemu_driver.c, src/qemu/qemu_migration.c:
	  Update for API change

2011-05-25  Daniel P. Berrange  <berrange@redhat.com>

	Fix preservation of errors across migration steps
	When doing migration, if an error occurs in Perform, it must not
	be overwritten during Finish/Confirm steps. If an error occurs
	in Finish, it must not be overwritten in Confirm.

	Previous commit a9d12c2444e43a0d3e5135eb15b4b62a7c011427 added
	code to qemudDomainMigrateFinish2 to preserve the error. This
	is not the right place, because it is not applicable in non-p2p
	migration. The src/libvirt.c virDomainMigrateV2/3 methods need
	code to preserve errors for non-p2p migration, while the
	doPeer2PeerMigrate2 and doPeer2PeerMigrate3 methods contain
	code to preverse errors for p2p migration.

	Remove the bogus error preservation from qemudDomainMigrateFinish2
	and qemudDomainMigrateFinish3.

	Fix virDomainMigrateV3 and doPeer2PeerMigrate3 so that they
	preserve any error hit during the Finish3 step, before invoking
	Confirm3.

	Finally if qemuMigrationFinish fails to resume the CPUs, it must
	preserve the error before tearing down the VM, so that VM cleanup
	doesn't overwrite it.

	* src/libvirt.c: Preserve error before invoking Confirm3
	* src/qemu/qemu_driver.c: Remove bogus error preservation
	  code in qemudDomainMigrateFinish2/qemudDomainMigrateFinish3
	* src/qemu/qemu_migration.c: Preserve error before invoking Confirm3
	  and after resume fails in qemuMigrationFinish.

	Fix error propagation in finish method for v3 migration
	Even when failing to start CPUs, the finish method was returning
	a success result. Fix this so that the QEMU process is killed
	off when finish fails under v3 protocol. Also rename the
	killOnFinish boolean to 'v3proto' to make it clearer that this
	is a tunable based on the migration protocol version

	* src/qemu/qemu_driver.c: Update for API change

	Fix SPICE seamless migration hostname
	The SPICE seamless migration process requires data to be passed
	back from the target host, to the source host via a cookie.
	The cookie includes the target host's hostname, but this was not
	stored, merely validated. This patch explicitly records the
	remote hostname after parsing the cookie, and uses it when
	initiating the SPICE migration

	* qemu/qemu_migration.c: Fix SPICE seamless migration hostname

	Fix resume on destination when doing non-live tunnelled migration
	Before running perform in peer-2-peer migration, the current

	  to fix non-live migration

2011-05-25  Daniel P. Berrange  <berrange@redhat.com>

	Introduce two method migration APIs
	There are two pieces of information which are desirable for
	migration, which cannot be supplied by applications

	 - The explicit QEMU migration URI, while using Peer2Peer
	   migration
	 - An override for the target VM XML

	This introduces two new public APIs to support these extra
	parameters. There is no need for extra wire protocool changes,
	since this is supported by the v3 migration enhancements

	* include/libvirt/libvirt.h.in,
	  src/libvirt.c, src/libvirt_public.syms: Add virDomainMigrate2
	  and virDomainMigrateToURI2

2011-05-25  Daniel P. Berrange  <berrange@redhat.com>

	Add a second URI parameter to virDomainMigratePerform3 method
	The virDomainMigratePerform3 currently has a single URI parameter
	whose meaning varies. It is either

	 - A QEMU migration URI (normal migration)
	 - A libvirtd connection URI (peer2peer migration)

	Unfortunately when using peer2peer migration, without also
	using tunnelled migration, it is possible that both URIs are
	required.

	This adds a second URI parameter to the virDomainMigratePerform3
	method, to cope with this scenario. Each parameter how has a fixed
	meaning.

	NB, there is no way to actually take advantage of this yet,
	since virDomainMigrate/virDomainMigrateToURI do not have any
	way to provide the 2 separate URIs

	* daemon/remote.c, src/remote/remote_driver.c,
	  src/remote/remote_protocol.x, src/remote_protocol-structs: Add
	  the second URI parameter to perform3 message
	* src/driver.h, src/libvirt.c, src/libvirt_internal.h: Add
	  the second URI parameter to Perform3 method
	* src/libvirt_internal.h, src/qemu/qemu_migration.c,
	  src/qemu/qemu_migration.h: Update to handle URIs correctly

2011-05-25  Daniel P. Berrange  <berrange@redhat.com>

	Extend v3 migration protocol to allow app supplied XML for target
	This extends the v3 migration protocol such that the
	virDomainMigrateBegin3 and virDomainMigratePerform3
	methods accept an application supplied XML config for
	the target VM.

	If the 'xmlin' parameter is NULL, then Begin3 uses the
	current guest XML as normal. A driver implementing the
	Begin3 method should either reject all non-NULL 'xmlin'
	parameters, or strictly validate that the app supplied
	XML does not change guest ABI.

	The Perform3 method also needed the xmlin parameter to
	cope with the Peer2Peer migration sequence.

	NB it is not yet possible to use this capability since
	neither of the public virDomainMigrate/virDomainMigrateToURI
	methods have a way to pass in XML.

	* daemon/remote.c, src/remote/remote_driver.c,
	  src/remote/remote_protocol.x, src/remote_protocol-structs:
	  Add 'remote_string xmlin' parameter to begin3/perform3
	  RPC messages
	* src/libvirt.c, src/driver.h, src/libvirt_internal.h: Add

	Fix initialization of current vcpus in libxl driver
	The cur_vcpus member of struct libxl_domain_build_info was incorrectly
	initialized to the number of vcpus, when it should have been interpreted
	as a bitmap, where bit X corresponds to online/offline status of vcpuX.

	To complicate matters, cur_vcpus is an int, so only 32 vcpus can be
	set online.  Add a check to ensure vcpus does not exceed this limit.

	V2: Eric Blake noted a compilation pitfal when '1 << 32' on an int.
	    Account for vcpus == 32.

	build: fix VIR_DEBUG on mingw
	We don't use the gnulib vsnprintf replacement, which means that

	virsh: optimize creation of default connection
	Ramon de Carvalho Valle reported a problem with:
	virsh connect qemu:///system
	as a non-root user.  The real root problem appears to be a regression
	in libvirtd being auto-started on the default qemu:///session URI;
	however, the symptom points to an independent flaw in virsh - we
	shouldn't be wasting efforts on making a connection if we aren't going
	to be using that connection.  Fixing virsh avoids Ramon's issue, while
	I work in the meantime to fix the real libvirtd regression.

	This patch looks big, but that's because 'gcc -Wmissing-field-initializers'
	gets triggered by './autobuild.sh --enable-compile-warnings=error', so I
	had to add 0 initialization to everyone (rather than my preference of
	just adding the non-zero flags to virshCmds and to cmdConnect).

	Meanwhile, if you use 'virsh -c URI', the connection must succeed; this
	patch _only_ optimizes the default connection to be deferred to a later
	point where we know if a particular command to be run needs a connection.

	Fix messages using VIR_ERR_XML_ERROR
	This error code has existed since the dawn of time, yet the messages it

	libvirt.h: consolidate typed parameter handling
	The new type is identical to the three old types that it replaces,
	and by creating a common type, this allows future patches to share
	common code that manipulates typed parameters.

	This change is backwards-compatible in API (recompilation works
	without any edits) and ABI (an older client that has not been
	recompiled uses the same layout) for code using only public
	names; only code using private names (those beginning with _)
	will have to adapt.

	* include/libvirt/libvirt.h.in (virTypedParameterType)
	(VIR_TYPED_PARAM_FIELD_LENGTH, _virTypedParameter): New enum,
	macro, and type.
	(virSchedParameter, virBlkioParameter, virMemoryParameter):
	Rewrite in terms of a common type, while keeping all old public
	names for backwards compatibility.

	Refactor tunnelled migration methods
	To facilitate the introduction of the v3 migration protocol,
	the doTunnelMigrate method is refactored into two pieces. One
	piece is intended to mirror the flow of virDomainMigrateVersion2,
	while the other is the helper for setting up sockets and processing
	the data.

	Previously socket setup would be done before the 'prepare' step,
	so errors could be dealt with immediately, avoiding need to shut
	off the destination QEMU. In the new split, socket setup is done
	after the 'prepare' step. This is not a serious problem, since
	the control flow already requires calling 'finish' to tear down
	the destination QEMU upon several errors.

	Introduce migration cookies to QEMU driver
	The migration protocol has support for a 'cookie' parameter which
	is an opaque array of bytes as far as libvirt is concerned. Drivers
	may use this for passing around arbitrary extra data they might
	need during migration. The QEMU driver needs to do a few things:

	 - Pass hostname/uuid to allow strict protection against localhost
	   migration attempts
	 - Pass SPICE/VNC server port from the target back to the source to
	   allow seamless relocation of client sessions
	 - Pass lock driver state from source to destination

	but only includes the host/guest UUID & name.

2011-05-16  Daniel P. Berrange  <berrange@redhat.com>

	Introduce yet another migration version in API.
	Migration just seems to go from bad to worse. We already had to
	introduce a second migration protocol when adding the QEMU driver,
	since the one from Xen was insufficiently flexible to cope with
	passing the data the QEMU driver required.

	It turns out that this protocol still has some flaws that we
	need to address. The current sequence is

	 *  Src: DumpXML
	          - Generate XML to pass to dst

	 *  Dst: Prepare
	          - Get ready to accept incoming VM
	          - Generate optional cookie to pass to src

	 *  Src: Perform
	          - Start migration and wait for send completion
	          - Kill off VM if successful, resume if failed

	 *  Dst: Finish
	          - Wait for recv completion and check status
	          - Kill off VM if unsuccessful

	The problems with this are:

	 - Since the first step is a generic 'DumpXML' call, we can't
	   add in other migration specific data. eg, we can't include
	   any VM lease data from lock manager plugins
	 - Since the first step is a generic 'DumpXML' call, we can't
	   emit any 'migration begin' event on the source, or have
	   any hook that runs right at the start of the process
	 - Since there is no final step on the source, if the Finish
	   method fails to receive all migration data & has to kill
	   the VM, then there's no way to resume the original VM
	   on the source

	This patch attempts to introduce a version 3 that uses the
	improved 5 step sequence

	 *  Src: Begin
	          - Generate XML to pass to dst
	          - Generate optional cookie to pass to dst

	 *  Dst: Prepare
	          - Get ready to accept incoming VM
	          - Generate optional cookie to pass to src

	 *  Src: Perform
	          - Start migration and wait for send completion
	          - Generate optional cookie to pass to dst

	 *  Dst: Finish
	          - Wait for recv completion and check status
	          - Kill off VM if failed, resume if success
	          - Generate optional cookie to pass to src

	 *  Src: Confirm
	          - Kill off VM if success, resume if failed

	The API is designed to allow both input and output cookies
	in all methods where applicable. This lets us pass around
	arbitrary extra driver specific data between src & dst during
	migration. Combined with the extra 'Begin' method this lets
	us pass lease information from source to dst at the start of
	migration

	Moving the killing of the source VM out of Perform and
	into Confirm, means we can now recover if the dst host
	can't successfully Finish receiving migration data.

	qemu: Update domain state when reconnecting monitor

	This API is supposed to replace virDomainGetInfo when the only purpose
	of calling it is getting current domain status.

	esx: Remove 1000 lines of generated but unused code
	Don't make all object and enum types (de)serializable by default.
	Detect this from the input file instead.

	esx: Generate implicit _this macros
	Several vSphere API methods are called on global objects like the
	FileManager, the PerformanceManager or the SearchIndex. The generator
	input file allows to mark such methods and the generator generates
	such method in a way that automatically handles marked parameter. This
	is done by some special macros. Those were manually written and this
	patch moves them to the generator.

	domain: Require <init> for container guests
	Use capabilities to allow a driver to register a default <init> if none

	LXC currently falls over if no init is specified, so an explicit error is
	an improvement IMO.

	(Side note: I don't think we can set a default value for LXC. If we use
	/sbin/init but the user doesn't specify a separate root FS for their guest,
	the container will rerun the host's init which can be traumatic :). For
	virt-install I'm thinking of defaulting to /sbin/init if a root FS has
	been specified, otherwise require the user to manually specify <init>)

	fix xdr detection and use with recent glibc
	glibc 2.13.90 has obsoleted its rpc implementation in favour of
	the one provided by the TI-RPC library:

	> * The RPC implementation in libc is obsoleted.  Old programs keep working
	>   but new programs cannot be linked with the routines in libc anymore.
	>   Programs in need of RPC functionality must be linked against TI-RPC.
	>   The TI-RPC implemtation is IPv6 enabled and there are other benefits.
	>
	>   Visible changes of this change include (obviously) the inability to
	>   link
	>   programs using RPC functions without referencing the TI-RPC library,
	>   the
	>   removal of the RPC headers from the glibc headers, and the lack of
	>   symbols defined in <rpc/netdb.h> when <netdb.h> is installed.
	>   Implemented by Ulrich Drepper.
	(from glibc NEWS)

	Thus with recent glibc, we need to try linking with -ltirpc when looking
	for the XDR functions. The daemon also needs to use XDR_CFLAGS to be able
	to find the XDR headers stored in /usr/include/tirpc.

	When using TI-RPC, there are some warnings about redundant declarations, but
	the fix probably belongs in other modules:

	/usr/include/tirpc/rpc/rpcent.h:68:13: warning: redundant redeclaration of
	'setrpcent' [-Wredundant-decls]
	/usr/include/rpc/netdb.h:53:13: note: previous declaration of 'setrpcent'
	was here

	/usr/include/tirpc/rpc/rpcent.h:69:13: warning: redundant redeclaration of
	'endrpcent' [-Wredundant-decls]
	/usr/include/rpc/netdb.h:54:13: note: previous declaration of 'endrpcent'
	was here

	/usr/include/tirpc/rpc/rpc.h:84:12: warning: redundant redeclaration of
	'bindresvport' [-Wredundant-decls]

	build: avoid gcc preprocessor extensions
	Use of ',##__VA_ARGS__' is a gcc extension not guaranteed by

	into the var-args set.

	(VIR_ERROR_INT, VIR_DEBUG, VIR_INFO, VIR_WARN, VIR_ERROR): Stick

	libvirt,logging: cleanup VIR_XXX0()
	These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.

	How do these coversions works? The magic is using the gcc extension of ##.
	When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
	avoid compile error.

	example: origin				after CPP
		high_level_api("%d", a_int)	low_level_api("%d", a_int)
		high_level_api("a  string")	low_level_api("a  string")

	About 400 conversions.

	8 special conversions:
	VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions
	VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions
	VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal)
	  (for security) 6 conversions

	xen: parse and generate hpet item in sxpr
	Recent versions of Xen disable the virtual HPET by default.  This is

	the HPET manually: 1) to test the emulation; 2) because distros may
	provide the knob while leaving the default to "enabled" for compatibility
	reasons.

	In preparation for removing generated files, it is necessary

	remote: avoid null dereference on error
	Clang found three instances of uninitialized use of nparams in

	couldn't see that ret->params.params_val is guaranteed to be
	NULL unless allocated within a function, and that nparams is
	guaranteed to be assigned prior to the allocation; hoisting the
	assignment to nparams to be earlier in the function shuts up
	that false positive.  But two of the reports also happened to

	cgroup: avoid leaking a file
	Clang detected a dead store to rc.  It turns out that in fixing this,
	I also found a FILE* leak.

	This is a subtle change in behavior, although unlikely to hit.  The
	pidfile is a kernel file, so we've probably got more serious problems
	under foot if we fail to parse one.  However, the previous behavior
	was that even if one pid file failed to parse, we tried others,
	whereas now we give up on the first failure.  Either way, though,
	the function returns -1, so the caller will know that something is
	going wrong, and that not all pids were necessarily reaped.  Besides,
	there were other instances already in the code where failure in the
	inner loop aborted the outer loop.

	* src/util/cgroup.c (virCgroupKillInternal): Abort rather than
	resuming loop on fscanf failure, and cleanup file on error.

	qemu: avoid null pointer dereference
	This code has had problems historically.  As originally

2011-04-28  Wen Congyang  <wency@cn.fujitsu.com>

	fix virsh's regression
	This patch does the following things:
	1. The return value of cmdSchedInfoUpdate() can be -1, 0 and 1. So the
	   type of return value should be int not bool.(This function is not a
	   entry of a virsh command, but the name of this function likes cmdXXX)

	2. The type of cmdSchedinfo()'s, cmdFreecell()'s, cmdPoolList()'s and
	   cmdVolList()'s return value is bool not int, so change the type of
	   variable ret_val, func_ret and functionReturn.

	3. Add a variable functionReturn for cmdMigrate(), cmdAttachInterface(),
	   cmdDetachInterface(), cmdAttachDisk() and cmdDetachDisk() to save the
	   return value.

	4. Change the type of variable ret in the function cmdAttachDevice(),
	   cmdDetachDevice(), cmdUpdateDevice(), cmdAttachInterface(),
	   cmdDetachInterface(), cmdAttachDisk() and cmdDetachDisk() to int, as
	   we use it to save the return value of virXXX() and the type of virXXX()'s
	   return value is int not bool.

	5. Do some cleanup when virBuff.error is 1.

	The bug 1-4 were introduced by commit b56fa5bb.

	   error: Failed to attach device from net.xml
	   error: internal error unable to execute QEMU command 'device_add': Device 'rtl8139' could not be initialized

	Before the refactoring all users of the ESX_VI__TEMPLATE__DISPATCH
	macro dispatched on the item type, as the item is the input to all those

	Commit ac1e6586ec75 made the dynamically dispatched CastFromAnyType
	functions use this macro too, but this functions dispatched on the
	actual type of the AnyType object. The item is the output of the

	Experimental libvirtd upstart job
	To install it, disable libvirtd sysv initscript:
	    chkconfig libvirtd off
	    service libvirtd stop

	and enable libvirtd upstart job:
	    cp  /usr/share/doc/libvirt-*/libvirtd.upstart \
	        /etc/init/libvirtd.conf
	    initctl reload-configuration
	    initctl start libvirtd

	libvirtd start/running, process 3929
	    killall -9 libvirtd
	    initctl status libvirtd
	libvirtd start/running, process 4047

	I looked into the possibility to use the upstart script from Ubuntu or
	at least getting inspiration from it but that's not possible. "expect
	daemon" is a nice thing but it only works if the process is defined with
	exec stanza instead of script ... no script. Unfortunately, with exec
	stanza environment variables can only be set within upstart script
	(i.e., configuration in /etc/sysconfig/libvirtd can't work). Hence, we
	need to use script stanza, source sysconfig, and execute libvirtd
	without --daemon. For similar reasons we can't use limit stanza and need
	to handle DAEMON_COREFILE_LIMIT in job's script.

	This patch does the following two things:
	1. hold an extra reference while handling watchdog event
	   If the domain is not persistent, and qemu quits unexpectedly before
	   calling processWatchdogEvent(), vm will be freed and the function
	   processWatchdogEvent() will be dangerous.

	2. unlock qemu driver and vm before returning from processWatchdogEvent()
	   When the function processWatchdogEvent() failed, we only free wdEvent,
	   but forget to unlock qemu driver and vm, free dumpfile.

	virsh: fix regression in parsing optional integer
	Regression introduced in 0.8.5, commit c1564268.  The command
	'virsh freecell 0' quit working when it changed from an optional
	string to an optional integer.

	This patch introduces a slight change that specifying an option
	twice is now detected as an error.  It also changes things so
	that a command that has more than 1 required option will not
	complain about missing options if one but not all of the options
	were given in long format, as in 'virsh vol-create --pool p file',
	as well as making positional parsing work for all optional
	options (each positional argument is associated with the earliest
	option that has not yet been seen by name).

	Optional boolean options can appear before required argument
	options, because they don't affect positional argument parsing,
	and obviously a required boolean option makes no sense.

	Technically, this patch renders VSH_OT_STRING and VSH_OT_DATA
	redundant; but cleaning that up can be a separate patch.

	No command should ever need more than 32 options, right? :)

	* tools/virsh.c (vshCmddefGetData, vshCmddefGetOption)
	(vshCommandCheckOpts): Alter parameters to use bitmaps.
	(vshCmddefOptParse): New function.
	(vshCommandParse): Update for better handling of positional
	arguments.
	(vshCmddefHelp): Allow unit tests to validate options.

2011-04-16  Eric Blake  <eblake@redhat.com>

	virsh: list required options first
	The current state of virsh parsing is that:

	$ virsh vol-info /path/to/image
	$ virsh vol-info --pool default /path/to/image
	$ virsh vol-info --pool default --vol /path/to/image

	all lookup the volume by path (technically, the last two also attempt
	a name lookup within a pool, whereas the first skips that step, but
	the end result is the same); meanwhile:

	$ virsh vol-info default /path/to/image

	complains about unexpected data.  Why?  Because the --pool option is
	optional, so default was parsed as the --vol argument, and
	/path/to/image.img doesn't match up with any remaining options that
	require an argument.  For proof, note that:

	$ virsh vol-info default --vol /path/to/image

	complains about looking up 'default' - the parser mis-associated both
	arguments with --vol.  Given the above, the only way to specify pool
	is with an explicit "--pool" argument (you can't specify it
	positionally).  However, named arguments can appear in any order, so:

	$ virsh vol-info /path/to/image --pool default
	$ virsh vol-info --vol /path/to/image --pool default

	have also always worked.  Therefore, this patch has no functional
	change on vol-info option parsing, but only on 'virsh help vol-info'
	synopsis layout.  However, it also allows the next patch to 1) enforce
	that required options are always first (without this patch, the next
	patch would fail the testsuite), and 2) allow the user to omit the
	"--pool" argument.  That is, the next patch makes it possible to do:

	$ virsh vol-info /path/to/image default

	which to date was not possible.

	* tools/virsh.c (opts_vol_create_from, opts_vol_clone)
	(opts_vol_upload, opts_vol_download, opts_vol_delete)

	(opts_vol_path): List optional pool parameter after required
	arguments.

	network: truncate bridges' dummy tap device names to IFNAMSIZ (15) chars
	This patch addresses:

	   https://bugzilla.redhat.com/show_bug.cgi?id=694382

	In order to give each libvirt-created bridge a fixed MAC address,
	commit 5754dbd56d4738112a86776c09e810e32f7c3224, added code to create
	a dummy tap device with guaranteed lowest MAC address and attach it to
	the bridge. This tap device was given the name "${bridgename}-nic".
	However, an interface device name must be IFNAMSIZ (15) characters or
	less, so a valid ${bridgename} such as "verylongname123" (15
	characters) would lead to an invalid tap device name
	("verylongname123-nic" - 19 characters), and that in turn led to a
	failure to bring up the network.

	The solution is to shorten the part of the original name used to
	generate the tap device name. However, simply truncating it is
	insufficient, because the last few characters of an interface name are
	often a number used to indicate one of a list of several similar
	devices (for example, "verylongname123", "verylongname124", etc) and
	simple truncation would lead to duplicate names (eg "verlongnam-nic"
	and "verylongnam-nic"). So instead we take the first 8 characters of
	$bridgename ("verylong" in the example), add on the final 3 bytes
	("123"), then add "-nic" (so "verylong123-nic").  Not pretty, but it
	is much more likely to generate a unique name, and is reproducible
	(unlike, say, a random number).

	sizeof(domain->name) is the wrong thing. Instead of using strdup here
	rewrite escape_specialcharacters to allocate the buffer itself.

	Add a contains_specialcharacters to be used in phypOpen, as phypOpen is
	not interested in the escaped version.

	PHYP: Adding network interface
	This is the implementation of the previous patch now using virInterface*
	API. Ended up this patch got much more simpler, smaller and easier to
	review. Here is some details:

	  * MAC size and interface name are fixed due to specifications on HMC,
	    both are created automatically and CAN'T be specified from user. They
	    have the following format:

	     * MAC: 122980003002
	     * Interface name: U9124.720.067BE8B-V3-C0

	  * I did replaced all the |grep|sed following the comments Eric Blake
	    did on the last patch.

	  * According to my last email, It's not possible to create a network
	    interface without assigning it to a specific lpar. Then, I am using
	    this very minimalistic XML file for testing:

	     <interface type='ethernet' name='LPAR01'>
	     </interface>

	    In this file I am using "name" as the lpar name which I am going to
	    assign the new network interface. I couldn't find a better way to
	    refer to it. Comments are welcome.

	  * Regarding the fact I am sleeping one second waiting for the HMC to
	    complete creation of the interface, I don't have means to check
	    if the whole process is done. All I do is execute a command, wait
	    until is complete (which is not enough in this case) check
	    the return and the exit status. The process of actually creating
	    a networking interface seems to take a little longer than just the
	    return of the ssh control.

	setmaxmem: add the new options to "virsh setmaxmem" command
	This patch adds the new options (--live, --config, and --current) to
	"virsh setmaxmem" command. The behavior of above options is the same
	as that of "virsh setmem".  When the --config option is specified, a
	modification is effective for the persistent domain, while the --live

	domain. The --current option is specified, it affects a current
	domain.

	examples except for the "default" network, since that is a faithful
	reproduction of the default network config that's automatically
	installed, which doesn't include any IPv6 address (for good reason -

	qemu: Remove the managed state file only if restoring succeeded
	1) Both "qemuDomainStartWithFlags" and "qemuAutostartDomain" try to
	restore the domain from managedsave'ed image if it exists (by
	invoking "qemuDomainObjRestore"), but it unlinks the image even
	if restoring fails, which causes data loss. (This problem exists
	for "virsh managedsave dom; virsh start dom").

	The fix for is to unlink the managed state file only if restoring
	succeeded.

	2) For "virsh save dom; virsh restore dom;", it can cause data
	corruption if one reuse the saved state file for restoring. Add
	doc to tell user about it.

	3) In "qemuDomainObjStart", if "managed_save" is NULL, we shouldn't
	fallback to start the domain, skipping it to cleanup as a incidental
	fix. Discovered by Eric.

	We should bind pci device to original driver when pciBindDeviceToStub() failed.

	This patch do the following things:
	1. rename the function as 'Unbind' is better than 'UnBind'.
	2. pciUnbindDeviceFromStub() will be used in the function pciBindDeviceToStub() in
	   next patch. Float it up, instead of having to have a forward declaration

	Change locking for udev monitor and callbacks
	We're seeing bugs apparently resulting from thread unsafety of
	libpciaccess, such as
	https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/726099
	To prevent those, as suggested by danpb on irc, move the
	nodeDeviceLock(driverState) higher into the callers.  In
	particular:

	  udevDeviceMonitorStartup should hold the lock while calling
	  udevEnumerateDevices(), and udevEventHandleCallback should hold it
	  over its entire execution.

	It's not clear to me whether it is ok to hold the
	nodeDeviceLock while taking the virNodeDeviceObjLock(dev) on a
	device.  If not, then the lock will need to be dropped around
	the calling of udevSetupSystemDev(), and udevAddOneDevice()
	may not actually be safe to call from higher layers with the
	driverstate lock held.

	libvirt 0.8.8 with this patch on it seems to work fine for me.
	Assuming it looks ok and I haven't done anything obviously dumb,
	I'll ask the bug submitters to try this patch.

	Allow relative path for qemu backing file
	This patch enables the relative backing file path support provided by
	qemu-img create.

	If a relative path is specified for the backing file, it is converted
	to an absolute path using the storage pool path. The absolute path is
	used to verify that the backing file exists. If the backing file exists,
	the relative path is allowed and will be provided to qemu-img create.

	build: detect potentential uninitialized variables
	Even with -Wuninitialized (which is part of autobuild.sh
	--enable-compile-warnings=error), gcc does NOT catch this
	use of an uninitialized variable:

	{
	  if (cond)
	    goto error;
	  int a = 1;
	error:
	  printf("%d", a);
	}

	which prints 0 (supposing the stack started life wiped) if
	cond was true.  Clang will catch it, but we don't use clang
	as often.  Using gcc -Wjump-misses-init catches it, but also
	gives false positives:

	{
	  if (cond)
	    goto error;
	  int a = 1;
	  return a;
	error:
	  return 0;
	}

	Here, a was never used in the scope of the error block, so
	declaring it after goto is technically fine (and clang agrees).
	However, given that our HACKING already documents a preference
	to C89 decl-before-statement, the false positive warning is
	enough of a prod to comply with HACKING.

	[Personally, I'd _really_ rather use C99 decl-after-statement
	to minimize scope, but until gcc can efficiently and reliably
	catch scoping and uninitialized usage bugs, I'll settle with
	the compromise of enforcing a coding standard that happens to
	reject false positives if it can also detect real bugs.]

	Fix libxl driver startup
	  When you happen to have a libvirtd binary compiled with the
	libxenlight driver (say you have installed xen-4.1 libraries)
	but not running a xen enabled system, then libvirtd fails to start.

	The cause is that libxlStartup() returns -1 when failing to initialize
	the library, and this propagates to virStateInitialize() which consider
	this a failure. We should only exit libxlStartup with an error code
	if something like an allocation error occurs, not if the driver failed
	to initialize.

	qemu: Ignore libvirt debug messages in qemu log
	qemu driver uses a 4K buffer for reading qemu log file. This is enough
	when only qemu's output is present in the log file. However, when
	debugging messages are turned on, intermediate libvirt process fills the
	log with a bunch of debugging messages before it executes qemu binary.
	In such a case the buffer may become too small. However, we are not
	really interested in libvirt messages so they can be filtered out from
	the buffer.

	qemu: fix regression with fd labeling on migration
	My earlier testing for commit 34fa0de0 was done while starting
	just-built libvirt from an unconfined_t shell, where the fds happened
	to work when transferring to qemu.  But when installed and run under
	virtd_t, failure to label the raw file (with no compression) or the
	pipe (with compression) triggers SELinux failures when passing fds
	over SCM_RIGHTS to svirt_t qemu.

	* src/qemu/qemu_migration.c (qemuMigrationToFile): When passing
	FDs, make sure they are labeled.

2011-03-29  Eric Blake  <eblake@redhat.com>

	qemu: improve error message on failed fd transfer
	First fallout of fd: migration - it looks like SELinux enforcing
	_does_ require fd labeling (running uninstalled libvirtd from an
	unconstrained shell had no problems, but once faked out by doing
	 chcon `stat -c %C /usr/sbin/libvirtd` daemon/libvirtd
	 run_init $PWD/daemon/libvirtd
	to run it with the same context as an init script service, and with
	SELinux enforcing, I got a rather confusing failure:
	error: Failed to save domain fedora_12 to fed12.img
	error: internal error unable to send TAP file handle: No file descriptor supplied via SCM_RIGHTS

	This fixes the error message, then I need to figure out a subsequent
	patch that does the fsetfilecon() necessary to keep things happy.
	It also appears that libvirtd hangs on a failed fd transfer; I don't
	know if that needs an independent fix.

	* src/qemu/qemu_monitor_text.c (qemuMonitorTextSendFileHandle):
	Improve message, since TAP is no longer only client.

	qemu: allow simple domain save to use fd: protocol
	This allows direct saves (no compression, no root-squash NFS) to use
	the more efficient fd: migration, which in turn avoids a race where
	qemu exec: migration can sometimes fail because qemu does a generic
	waitpid() that conflicts with the pclose() used by exec:.  Further
	patches will solve compression and root-squash NFS.

2011-03-29  Eric Blake  <eblake@redhat.com>

	qemu: fix restoring a compressed save image
	Latent bug introduced in commit 2d6a581960 (Aug 2009), but not exposed
	until commit 1859939a (Jan 2011).  Basically, when virExec creates a
	pipe, it always marks libvirt's side as cloexec.  If libvirt then
	wants to hand that pipe to another child process, things work great if
	the fd is dup2()'d onto stdin or stdout (as with stdin: or exec:
	migration), but if the pipe is instead used as-is (such as with fd:
	migration) then qemu sees EBADF because the fd was closed at exec().

	This is a minimal fix for the problem at hand; it is slightly racy,
	but no more racy than the rest of libvirt fd handling, including the
	case of uncompressed save images.  A more invasive fix, but ultimately
	safer at avoiding leaking unintended fds, would be to _always and
	atomically_ open all fds as cloexec in libvirt (thanks to primitives
	like open(O_CLOEXEC), pipe2(), accept4(), ...), then teach virExec to
	clear that bit for all fds explicitly marked to be handed to the child
	only after forking.

	Remove the Open Nebula driver
	The Open Nebula driver has been unmaintained since it was first
	introduced. The only commits have been for tree-wide cleanups.
	It also has a major design flaw, in that it only knows about guests
	that it has created itself, which makes it of very limited use.

	Discussions wrt evolution of the VMWare ESX driver, concluded that
	it should limit itself to single-node ESX operation and not try to
	manage the multi-node architecture of VirtualCenter. Open Nebula
	is a cluster like Virtual Center, not a single node system, so
	the same reasoning applies.

	The DeltaCloud project includes an Open Nebula driver and is a much
	better fit architecturally, since it is explicitly targetting the
	distributed multihost cluster scenario.

	Thus this patch deletes the libvirt Open Nebula driver with the
	recommendation that people use DeltaCloud for managing it instead.

2011-03-28  Daniel Veillard  <veillard@redhat.com>

	Update on the goal page
	Some things to note in this patch:
	   - we do extend libvirt scope beyond purely managing domains, there is
	     already a number of blocks which are here as helpr functions to
	     manage the resources on the host.
	   - we are expanding in the direction of libvirt being sufficient to do
	     most of the management on the Host (but within the limits of the need
	     for virtualization, e.g. managing users on the host is out of scope)
	   - we don't require anymore APIs to be supported by multiple
	     hypervisors to get in, it's already the case in practice, but we
	     should still make sure the semantic of those APIs are clear. We
	     added quite a bit for QEmu, but for example I saw on IRC that VBox
	     could emulate a network unplug/replug on a domain interface, and
	     that would be a good addition even if a priori no other hypervisor
	     supports it.
	   - Make clear that all libvirt APIs are available remotely, which is
	     key to use libvirt for building management tools.
	   - link the goal page from the project main page

	As for libvirt project directions, I think it just reflects the natural
	evolution in the last couple of years. We are less hypervisor agnostic
	and extending in the Host management. Clearly there is interest in
	making sure libvirt is complete in term of features for the hypervisors
	supported, especially the ones like KVM or LXC which don't really have
	integrated management library.

	Get cpu time and current memory balloon from libxl

2011-03-24  Jiri Denemark  <jdenemar@redhat.com>

	Make error reporting in libvirtd thread safe
	Bug https://bugzilla.redhat.com/show_bug.cgi?id=689374 reported libvirtd
	crash during error dispatch.

	The reason is that libvirtd uses remoteDispatchConnError() with non-NULL
	conn parameter which means that virConnGetLastError() is used instead of
	its thread safe replacement virGetLastError().

	So when several libvirtd threads are reporting errors at the same time,
	the errors can get mixed or corrupted or in case of bad luck libvirtd
	itself crashes.

	Since Daniel B. is going to rewrite this code from scratch on top of his
	RPC infrastructure, I tried to come up with a minimal fix. Thus,
	remoteDispatchConnError() now just ignores its conn argument and always
	calls virGetLastError(). However, several callers had to be touched as
	well, since no libvirt API is allowed to be called before dispatching
	the error. Doing so would reset the error and we would have nothing to
	dispatch. As a result of that, the code is not very nice but that
	doesn't really make daemon/remote.c worse than it is now :-) And it will
	all die soon, which is good.

	The bug report also contains a reproducer in C which detects both mixed
	up error messages and libvirtd crash. Before this patch, I was able to
	crash libvirtd in about 20 seconds up to 3 minutes depending on number
	of CPU cores (more is better) and luck.

	   error: Failed to attach disk
	   error: operation failed: adding lsi,id=scsi0,bus=pci.0,addr=0x6 device failed: Duplicate ID 'scsi0' for device

	util: Fix return value for virJSONValueFromString if it fails
	Problem:
	  "parser.head" is not NULL even if it's free'ed by "virJSONValueFree",
	returning "parser.head" when "virJSONValueFromString" fails will cause
	unexpected errors (libvirtd will crash sometimes), e.g.
	  In function "qemuMonitorJSONArbitraryCommand":

	        if (!(cmd = virJSONValueFromString(cmd_str)))
	            goto cleanup;

	        if (qemuMonitorJSONCommand(mon, cmd, &reply) < 0)
	            goto cleanup;

	        ......

	     cleanup:
	        virJSONValueFree(cmd);

	  It will continues to send command to monitor even if "virJSONValueFromString"
	is failed, and more worse, it trys to free "cmd" again.

	  Crash example:
	{"error":{"class":"QMPBadInputObject","desc":"Expected 'execute' in QMP input","data":{"expected":"execute"}}}
	{"error":{"class":"QMPBadInputObject","desc":"Expected 'execute' in QMP input","data":{"expected":"execute"}}}
	error: server closed connection:
	error: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Connection refused
	error: failed to connect to the hypervisor

	  This fix is to:
	    1) return NULL for failure of "virJSONValueFromString",
	    2) and it seems "virJSONValueFree" uses incorrect loop index for type
	       of "VIR_JSON_TYPE_OBJECT", fix it together.

	destination host. This is similar to the usage of PREASSOCIATE during
	migration in 8021qbg libvirt code today. PREASSOCIATE-RR is a VDP operation.
	With the latest at IEEE, 8021qbh will need to support VDP operations.
	A corresponding enic driver patch to support PREASSOCIATE-RR for 8021qbh
	will be posted for net-next-2.6 inclusion soon.

	qemu: simplify PCI configfd handling in monitor
	This is also a bug fix - on the error path, qemu_hotplug would
	leave the configfd file leaked into qemu.  At least the next
	attempt to hotplug a PCI device would reuse the same fdname,
	and when the qemu getfd monitor command gets a new fd by the
	same name as an earlier one, it closes the earlier one, so there
	is no risk of qemu running out of fds.

	network driver: log error and abort network startup when radvd isn't found
	This is detailed in:

	  https://bugzilla.redhat.com/show_bug.cgi?id=688957

	Since radvd is executed by daemonizing it, the attempt to exec the
	radvd binary doesn't happen until after libvirtd has already received
	an exit code from the intermediate forked process, so no error is
	detected or logged by __virExec().

	We can't require radvd as a prerequisite for the libvirt package (many
	installations don't use IPv6, so they don't need it), so instead we
	add in a check to verify there is an executable radvd binary prior to
	trying to exec it.

	Fix delayed event delivery when SASL is active
	When SASL is active, it was possible that we read and decoded

	event loop.

	This is a counterpart to the same kind of issue solved in

	Add libxenlight driver
	Add a new xen driver based on libxenlight [1], which is the primary
	toolstack starting with Xen 4.1.0.  The driver is stateful and runs
	privileged only.

	Like the existing xen-unified driver, the libxenlight driver is
	accessed with xen:// URI.  Driver selection is based on the status
	of xend.  If xend is running, the libxenlight driver will not load
	and xen:// connections are handled by xen-unified.  If xend is not
	running *and* the libxenlight driver is available, xen://
	connections are deferred to the libxenlight driver.

	V6:
	 - Address several code style issues noted by Daniel Veillard
	 - Make drive work with xen:/// URI
	 - Hold domain object reference while domain is injected in
	   libvirt event loop.  Race found and fixed by Markus Groß.

	V5:
	 - Ensure events are unregistered when domain private data
	   is destroyed.  Discovered and fixed by Markus Groß.

	V4:
	 - Handle restart of libvirtd, reconnecting to previously
	   started domains
	 - Rebased to current master
	 - Tested against Xen 4.1 RC7-pre (c/s 22961:c5d121fd35c0)

	V3:
	  - Reserve vnc port within driver when autoport=yes

	V2:

	  - Rebased to current master
	  - Plug memory leaks found by Stefano Stabellini and valgrind

	qemu: Fix copy&paste error messages in text monitor

2011-03-18  Wen Congyang  <wency@cn.fujitsu.com>

	do not unref obj in qemuDomainObjExitMonitor*
	Steps to reproduce this bug:
	# cat test.sh
	  #! /bin/bash -x
	  virsh start domain
	  sleep 5
	  virsh qemu-monitor-command domain 'cpu_set 2 online' --hmp
	# while true; do ./test.sh ; done

	Then libvirtd will crash.

	The reason is that:
	we add a reference of obj when we open the monitor. We will reduce this
	reference when we free the monitor.

	If the reference of monitor is 0, we will free monitor automatically and
	the reference of obj is reduced.

	But in the function qemuDomainObjExitMonitorWithDriver(), we reduce this
	reference again when the reference of monitor is 0.

	It will cause the obj be freed in the function qemuDomainObjEndJob().

	Then we start the domain again, and libvirtd will crash in the function
	virDomainObjListSearchName(), because we pass a null pointer(obj->def->name)
	to strcmp().

	Avoid taking lock in libvirt debug dump
	As pointed out, locking the buffer from the signal handler

	The domain has 2 cpus, and we try to set the third cpu online.
	The qemu crashes, and this command will hang.

	The reason is that the refs is not 1 when we unwatch the monitor.
	We lock the monitor, but we do not unlock it. So virCondWait()

	macvtap: log an error if on failure to connect to netlink socket
	A bug in libnl (see https://bugzilla.redhat.com/show_bug.cgi?id=677724
	and https://bugzilla.redhat.com/show_bug.cgi?id=677725) makes it very
	easy to create a failure to connect to the netlink socket when trying
	to open a macvtap network device ("type='direct'" in domain interface
	XML). When that error occurred (during a call to libnl's nl_connect()
	from libvirt's nlComm(), there was no log message, leading virsh (for
	example) to report "unknown error".

	There were two other cases in nlComm where an error in a libnl
	function might return with failure but no error reported. In all three
	cases, this patch logs a message which will hopefully be more useful.

	Note that more detailed information about the failure might be
	available from libnl's nl_geterror() function, but it calls
	strerror(), which is not threadsafe, so we can't use it.

	qemu: improve efficiency of dd during snapshots
	POSIX states about dd:

	If the bs=expr operand is specified and no conversions other than
	sync, noerror, or notrunc are requested, the data returned from each
	input block shall be written as a separate output block; if the read
	returns less than a full block and the sync conversion is not
	specified, the resulting output block shall be the same size as the
	input block. If the bs=expr operand is not specified, or a conversion
	other than sync, noerror, or notrunc is requested, the input shall be
	processed and collected into full-sized output blocks until the end of
	the input is reached.

	Since we aren't using conv=sync, there is no zero-padding, but our
	use of bs= means that a short read results in a short write.  If
	instead we use ibs= and obs=, then short reads are collected and dd
	only has to do a single write, which can make dd more efficient.

	* src/qemu/qemu_monitor.c (qemuMonitorMigrateToFile):
	Avoid 'dd bs=', since it can cause short writes.

	Fix misc bugs in virCommandPtr
	The virCommandNewArgs() method would free the virCommandPtr

	Make LXC container startup/shutdown/I/O more robust
	The current LXC I/O controller looks for HUP to detect
	when a guest has quit. This isn't reliable as during
	initial bootup it is possible that 'init' will close
	the console and let mingetty re-open it. The shutdown
	of containers was also flakey because it only killed
	the libvirt I/O controller and expected container
	processes to gracefully follow.

	Change the I/O controller such that when it see HUP
	or an I/O error, it uses kill($PID, 0) to see if the
	process has really quit.

	Change the container shutdown sequence to use the
	virCgroupKillPainfully function to ensure every
	really goes away

	audit: eliminate potential null pointer deref when auditing macvtap devices
	The newly added call to qemuAuditNetDevice in qemuPhysIfaceConnect was
	assuming that res_ifname (the name of the macvtap device) was always
	valid, but this isn't the case. If openMacvtapTap fails, it always
	returns NULL, which would result in a segv.

	Since the audit log only needs a record of devices that are actually
	sent to qemu, and a failure to open the macvtap device means that no
	device will be sent to qemu, we can solve this problem by only doing
	the audit if openMacvtapTap is successful (in which case res_ifname is
	guaranteed valid).

	network driver: don't send default route to clients on isolated networks
	Normally dnsmasq will send a default route (the address of the host in
	the network definition) to any client requesting an address via
	DHCP. On an isolated network this makes no sense, as we have iptables
	to prevent any traffic going out via that interface, so anything sent
	that way would be dropped anyway.

	This extra/unusable default route becomes problematic if you have
	setup a guest with multiple network interfaces, with one connected to
	an isolated network and another that provides connectivity to the
	outside (example - one interface directly connecting to a physical
	interface via macvtap, with a second connected to an isolated network
	so that the host and guest can communicate (macvtap doesn't support
	guest<->host communication without an external switch that supports
	vepa, or reflecting all traffic back)). In this case, if the guest
	chooses the default route of the isolated network, the guest will not
	be able to get network traffic beyond the host.

	To prevent dnsmasq from sending a default route, you can tell it to
	send 0 bytes of data for the default route option (option number 3)
	with --dhcp-option=3 (normally the data to send for the option would
	follow the option number; no extra data means "don't send this option").

	I have checked on RHEL5 (a good representative of the oldest supported
	libvirt platforms) and its version of dnsmasq (2.45) does support
	--dhcp-option, so this shouldn't create any compatibility problems.

	python: Use hardcoded python path in libvirt.py
	This partially reverts (and fixes that part in a different way) commit
	e4384459c93e3e786aa483c7f077d1d22148f689, which replaced
	``/usr/bin/python'' with ``/usr/bin/env python'' in all examples or
	scripts used during build to generate other files.

	However, python bindings module is compiled and linked against a
	specific python discovered or explicitly provided in configure phase.
	Thus libvirt.py, which is generated and installed into the system,
	should use the same python binary for which the module has been built.

	The hunk in Makefile.am replaces $(srcdir) with $(PYTHON), which might
	seem wrong but it is not. generator.py didn't use any of its command
	line arguments so passing $(srcdir) to it was redundant.

	network driver: Use a separate dhcp leases file for each network
	By default, all dnsmasq processes share the same leases file. libvirt
	also uses the --dhcp-lease-max option to control the maximum number of
	leases allowed. The problem is that libvirt puts in a number equal to
	the number of addresses in the range for the one network handled by a
	single instance of dnsmasq, but dnsmasq checks the total number of
	leases in the file (which could potentially contain many more).

	The solution is to tell each instance of dnsmasq to create and use its
	own leases file. (/var/lib/libvirt/network/<net-name>.leases).

	This file is created by dnsmasq when it starts, but not deleted when
	it exists. This is fine when the network is just being stopped, but if
	the leases file was left around when a network was undefined, we could
	end up with an ever-increasing number of dead files - instead, we
	explicitly unlink the leases file when a network is undefined.

	Note that Ubuntu carries a patch against an older version of libvirt for this:

	hhttps://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/713071
	ttp://bazaar.launchpad.net/~serge-hallyn/ubuntu/maverick/libvirt/bugall/revision/109

	libvirt-users, but couldn't find it.

	network driver: Fix indentation from previous commit

2011-03-12  Laine Stump  <laine@laine.org>

	network driver: Start dnsmasq even if no dhcp ranges/hosts are specified.
	This fixes a regression introduced in commit ad48df, and reported on
	the libvirt-users list:

	  https://www.redhat.com/archives/libvirt-users/2011-March/msg00018.html

	The problem in that commit was that we began searching a list of ip
	address definitions (rather than just having one) to look for a dhcp
	range or static host; when we didn't find any, our pointer (ipdef) was
	left at NULL, and when ipdef was NULL, we returned without starting up
	dnsmasq.

	Previously dnsmasq was started even without any dhcp ranges or static
	entries, because it's still useful for DNS services.

	Another problem I noticed while investigating was that, if there are
	IPv6 addresses, but no IPv4 addresses of any kind, we would jump out
	at an ever higher level in the call chain.

	This patch does the following:

	1) networkBuildDnsmasqArgv() = all uses of ipdef are protected from
	   NULL dereference. (this patch doesn't change indentation, to make
	   review easier. The next patch will change just the
	   indentation). ipdef is intended to point to the first IPv4 address
	   with DHCP info (or the first IPv4 address if none of them have any
	   dhcp info).

	2) networkStartDhcpDaemon() = if the loop looking for an ipdef with
	   DHCP info comes up empty, we then grab the first IPv4 def from the
	   list. Also, instead of returning if there are no IPv4 defs, we just
	   return if there are no IP defs at all (either v4 or v6). This way a
	   network that is IPv6-only will still get dnsmasq listening for DNS
	   queries.

	3) in networkStartNetworkDaemon() - we will startup dhcp not just if there
	   are any IPv4 addresses, but also if there are any IPv6 addresses.

	domain.rng vs. formatdomain.html#elementsUSB
	The Relax-NG schema for domains regarding <hostdev> doesn't match what's
	implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The
	implementation only requires @type, but the schema currently either
	required none or all three attributes (@mode, @type, and @managed) to be
	defined together, because they are declared in the same
	<optional)-section. (@managed is currently even undocumented on
	<http://libvirt.org/formatdomain.html#elementsUSB>).

	Thus the following minimal <hostdev>-example fails to validate:
	<domain type='test'>
	        <name>N</name>
	        <memory>4096</memory>
	        <bootloader>/bin/false</bootloader>
	        <os>
	                <type arch='x86_64' machine='xenpv'>linux</type>
	        </os>
	        <devices>
	                <hostdev type='pci'>
	                        <source>
	                                <address bus='0x06' slot='0x00' function='0x0'/>
	                        </source>
	                </hostdev>
	        </devices>
	</domain>

	The schema is changed to match the current implementation:
	1. @mode is optional (which defaults to 'subsystem')
	2. @type is required
	3. @managed is optional (which defaults to 'no')

	The documentation is updated to mention @managed.

	Ignore backing file errors in FS storage pool
	Currently a single storage volume with a broken backing file will disable the
	whole storage pool. This can happen when the backing file is on some
	unavailable network storage or if the backing volume is deleted, while the
	storage volumes using it remain.
	Since the storage pool can not be re-activated, re-creating the missing
	or deleting the now useless volumes using libvirt only is not possible.

	Fixing this is a little bit tricky:
	1. virStorageBackendProbeTarget() only detects the missing backing file,
	   if the backing file format is not explicitly specified. If the
	   backing file is created using
		   kvm-img create -f qcow2 -o backing_fmt=qcow2,backing_file=... ...
	   no error is detected at this stage.
	   The new return code -3 signals that the backing file could not be
	   opened.
	2. The backingStore.format must be >= 0, since values < 0 would break
	   virStorageVolTargetDefFormat() when dumping the XML data such as
	       <format type='...'/>
	   Because of this the format is faked as VIR_STORAGE_FILE_RAW.
	3. virStorageBackendUpdateVolTargetInfo() always opens the backing file
	   and thus always detects a missing backing file.
	   Since it "only" updates the capacity, allocation, owner, group, mode
	   and SELinux label, just ignore errors at this stage, print an error
	   message and continue.
	4. Using vol-dump on a broken volume still doesn't work, but at least
	   vol-destroy and pool-refresh do work now.

	To reproduce:
	  dir=$(mktemp -d)
	  virsh pool-create-as tmp dir '' '' '' '' "$dir"
	  virsh vol-create-as --format qcow2 tmp back 1G
	  virsh vol-create-as --format qcow2 --backing-vol-format qcow2 --backing-vol back tmp cow 1G
	  virsh vol-delete --pool tmp back
	  virsh pool-refresh tmp
	After the last step, the pool will be gone (because it was not persistent). As
	long as the now broken image stays in the directory, you will not be able to
	re-create or re-start the pool.

	audit: audit use of /dev/net/tun, /dev/tapN, /dev/vhost-net
	Opening raw network devices with the intent of passing those fds to
	qemu is worth an audit point.  This makes a multi-part audit: first,
	we audit the device(s) that libvirt opens on behalf of the MAC address
	of a to-be-created interface (which can independently succeed or
	fail), then we audit whether qemu actually started the network device
	with the same MAC (so searching backwards for successful audits with
	the same MAC will show which fd(s) qemu is actually using).  Note that
	it is possible for the fd to be successfully opened but no attempt
	made to pass the fd to qemu (for example, because intermediate
	nwfilter operations failed) - no interface start audit will occur in
	that case; so the audit for a successful opened fd does not imply
	rights given to qemu unless there is a followup audit about the
	attempt to start a new interface.

	Likewise, when a network device is hot-unplugged, there is only one
	audit message about the MAC being discontinued; again, searching back
	to the earlier device open audits will show which fds that qemu quits
	using (and yes, I checked via /proc/<qemu-pid>/fd that qemu _does_
	close out the fds associated with an interface on hot-unplug).  The
	code would require much more refactoring to be able to definitively
	state which device(s) were discontinued at that point, since we
	currently don't record anywhere in the XML whether /dev/vhost-net was
	opened for a given interface.

	cgroup: allow fine-tuning of device ACL permissions
	Adding audit points showed that we were granting too much privilege
	to qemu; it should not need any mknod rights to recreate any
	devices.  On the other hand, lxc should have all device privileges.
	The solution is adding a flag parameter.

	This also lets us restrict write access to read-only disks.

	qemu: Support vram for video of qxl type
	For qemu names the primary vga as "qxl-vga":

	  1) if vram is specified for 2nd qxl device:

	    -vga qxl -global qxl-vga.vram_size=$SIZE \
	    -device qxl,id=video1,vram_size=$SIZE,...

	  2) if vram is not specified for 2nd qxl device, (use the default
	     set by global):

	    -vga qxl -global qxl-vga.vram_size=$SIZE \
	    -device qxl,id=video1,...

	For qemu names all qxl devices as "qxl":

	  1) if vram is specified for 2nd qxl device:

	    -vga qxl -global qxl.vram_size=$SIZE \
	    -device qxl,id=video1,vram_size=$SIZE ...

	  2) if vram is not specified for 2nd qxl device:

	    -vga qxl -global qxl-vga.vram_size=$SIZE \
	    -device qxl,id=video1,...

	"-global" is the only way to define vram_size for the primary qxl
	device, regardless of how qemu names it, (It's not good a good
	way, as original idea of "-global" is to set a global default for
	a driver property, but to specify vram for first qxl device, we
	have to use it).

	For other qxl devices, as they are represented by "-device", could
	specify it directly and seperately for each, and it overrides the
	default set by "-global" if specified.

	v1 - v2:
	  * modify "virDomainVideoDefaultRAM" so that it returns 16M as the
	    default vram_size for qxl device.

	  * vram_size * 1024 (qemu accepts bytes for vram_size).

	  * apply default vram_size for qxl device for which vram_size is
	    not specified.

	  * modify "graphics-spice" tests (more sensiable vram_size)

	  * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr,
	    to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr).

	v2 - v3:
	  * Modify default video memory size for qxl device from 16M to 24M

	  * Update codes to be consistent with changes on qemu_capabilities.*

	* daemon/libvirtd.c: change default logging to go to libvirtd.log

	Force all logs to go to the round robbin memory buffer
	Initially only the log actually written out by libvirt were

	qemu: avoid corruption of domain hashtable and misuse of freed domains
	This was also found while investigating

	   https://bugzilla.redhat.com/show_bug.cgi?id=670848

	An EOF on a domain's monitor socket results in an event being queued
	to handle the EOF. The handler calls qemuProcessHandleMonitorEOF. If
	it is a transient domain, this leads to a call to
	virDomainRemoveInactive, which removes the domain from the driver's
	hashtable and unref's it. Nowhere in this code is the qemu driver lock
	acquired.

	However, all modifications to the driver's domain hashtable *must* be
	done while holding the driver lock, otherwise the hashtable can become
	corrupt, and (even more likely) another thread could call a different
	hashtable function and acquire a pointer to the domain that is in the
	process of being destroyed.

	To prevent such a disaster, qemuProcessHandleMonitorEOF must get the
	qemu driver lock *before* it gets the DomainObj's lock, and hold it
	until it is finished with the DomainObj. This guarantees that nobody
	else modifies the hashtable at the same time, and that anyone who had
	already gotten the DomainObj from the hashtable prior to this call has
	finished with it before we remove/destroy it.

2011-03-04  Laine Stump  <laine@laine.org>

	qemu: Add missing lock of virDomainObj before calling virDomainUnref
	This was found while researching the root cause of:

	https://bugzilla.redhat.com/show_bug.cgi?id=670848

	virDomainUnref should only be called with the lock held for the
	virDomainObj in question. However, when a transient qemu domain gets
	EOF on its monitor socket, it queues an event which frees the monitor,
	which unref's the virDomainObj without first locking it. If another
	thread has already locked the virDomainObj, the modification of the
	refcount could potentially be corrupted. In an extreme case, it could
	also be potentially unlocked by virDomainObjFree, thus left open to
	modification by anyone else who would have otherwise waited for the
	lock (not to mention the fact that they would be accessing freed
	data!).

	The solution is to have qemuMonitorFree lock the domain object right
	before unrefing it. Since the caller to qemuMonitorFree doesn't expect
	this lock to be held, if the refcount doesn't go all the way to 0,
	qemuMonitorFree must unlock it after the unref.

	util: Allow removing hash entries in virHashForEach
	This fixes a possible crash of libvirtd during its startup. When qemu
	driver reconnects to running domains, it iterates over all domain
	objects in a hash. When reconnecting to an associated qemu monitor
	fails and the domain is transient, it's immediately removed from the
	hash. Despite the fact that it's explicitly forbidden to do so. If
	libvirtd is lucky enough, virHashForEach will access random memory when
	the callback finishes and the deamon will crash.

	Since it's trivial to fix virHashForEach to allow removal of hash
	entries while iterating through them, I went this way instead of fixing
	qemuReconnectDomain callback (and possibly others) to avoid deleting the
	entries.

	build: Fix API docs generation in VPATH build
	XSLT allows for two ways of generating the output of transformation.
	Either implicit, which xsltproc prints to stdout and can be redirected
	to a file using -o file. Or explicit, which means the stylesheet
	contains <xsl:document> element which specifies where the output should
	be saved. This can be used for generating more files by a single run of
	xsltproc and -o directory/ can change the directory where the output
	files will be stored.

	devhelp.xsl is special in that it combines both options in one
	stylesheet, which doesn't work well with -o:

	xsltproc --nonet -o ./devhelp/ ./devhelp/devhelp.xsl ./libvirt-api.xml

	Outputs 4 *.html files into ./devhelp but then tries to write to
	./devhelp/ as a file (hence the I/O error) rather than writing output to
	the fifth file devhelp/libvirt.devhelp.

	This patch modifies devhelp.xsl so that all files are generated using
	<xsl:document> element and -o directory/ can be used to override output
	directory where those files are saved.

2011-02-21  Daniel P. Berrange  <berrange@redhat.com>

	Remove all object hashtable caches from virConnectPtr
	The virConnectPtr struct will cache instances of all other
	objects. APIs like virDomainLookupByUUID will return a
	cached object, so if you do virDomainLookupByUUID twice in
	a row, you'll get the same exact virDomainPtr instance.

	This does not have any performance benefit, since the actual
	logic in virDomainLookupByUUID (and other APIs returning
	virDomainPtr, etc instances) is not short-circuited. All
	it does is to ensure there is only one single virDomainPtr
	in existance for any given UUID.

	The caching has a number of downsides though, all relating
	to stale data. If APIs aren't careful to always overwrite
	the 'id' field in virDomainPtr it may become out of data.
	Likewise for the name field, if a guest is renamed, or if
	a guest is deleted, and then a new one created with the
	same UUID but different name.

	This has been an ongoing, endless source of bugs for all
	applications using libvirt from languages with garbage
	collection, causing them to get virDomainPtr instances
	from long ago with stale data.

	The caching is also a waste of memory resources, since
	both applications, and language bindings often maintain
	their own hashtable caches of object instances.

	This patch removes all the hash table caching, so all
	APIs return brand new virDomainPtr (etc) object instances.

	* src/datatypes.h: Delete all hash tables.
	* src/datatypes.c: Remove all object caching code

	remove duplicated call to reportOOMError

	remove space between function name and (
	There were several occurrences of an extra space inserted between
	a function name and the ( opening the argument list in
	datatypes.c. This is not consistent with the coding style used in
	the rest of this file so removing this extra space makes the
	code slightly more readable.

	don't check for NULL before calling virHashFree
	virHashFree follows the convention described in HACKING that
	XXXFree() functions can be called with a NULL argument.

	remove no longer needed calls to virReportOOMError
	Now that the virHash handling functions call virReportOOMError by
	themselves when needed, users of the virHash API no longer need to
	do it by themselves. Since users of the virHash API were not
	consistently calling virReportOOMError after memory failures from
	the virHash code, this has the added benefit of making OOM
	reporting from this code more consistent and reliable.

	factor common code in virHashAddEntry and virHashUpdateEntry
	The only difference between these 2 functions is that one errors
	out when the entry is already present while the other modifies
	the existing entry. Add an helper function with a boolean argument
	indicating whether existing entries should be updated or not, and
	use this helper in both functions.

	add hash table rebalancing in virHashUpdateEntry
	The code in virHashUpdateEntry and virHashAddEntry is really
	similar. However, the latter rebalances the hash table when
	one of its buckets contains too many elements while the former
	does not. Fix this discrepancy.

	Give each virtual network bridge its own fixed MAC address
	This fixes https://bugzilla.redhat.com/show_bug.cgi?id=609463

	The problem was that, since a bridge always acquires the MAC address
	of the connected interface with the numerically lowest MAC, as guests
	are started and stopped, it was possible for the MAC address to change
	over time, and this change in the network was being detected by
	Windows 7 (it sees the MAC of the default route change), so on each
	reboot it would bring up a dialog box asking about this "new network".

	The solution is to create a dummy tap interface with a MAC guaranteed
	to be lower than any guest interface's MAC, and attach that tap to the
	bridge as soon as it's created. Since all guest MAC addresses start
	with 0xFE, we can just generate a MAC with the standard "0x52, 0x54,
	0" prefix, and it's guaranteed to always win (physical interfaces are
	never connected to these bridges, so we don't need to worry about
	competing numerically with them).

	Note that the dummy tap is never set to IFF_UP state - that's not
	necessary in order for the bridge to take its MAC, and not setting it
	to UP eliminates the clutter of having an (eg) "virbr0-nic" displayed
	in the output of the ifconfig command.

	I chose to not auto-generate the MAC address in the network XML
	parser, as there are likely to be consumers of that API that don't
	need or want to have a MAC address associated with the
	bridge.

	Instead, in bridge_driver.c when the network is being defined, if
	there is no MAC, one is generated. To account for virtual network
	configs that already exist when upgrading from an older version of
	libvirt, I've added a %post script to the specfile that searches for
	all network definitions in both the config directory
	(/etc/libvirt/qemu/networks) and the state directory
	(/var/lib/libvirt/network) that are missing a mac address, generates a
	random address, and adds it to the config (and a matching address to
	the state file, if there is one).

	Add txmode attribute to interface XML for virtio backend
	This is in response to:

	   https://bugzilla.redhat.com/show_bug.cgi?id=629662

	Explanation

	qemu's virtio-net-pci driver allows setting the algorithm used for tx
	packets to either "bh" or "timer". This is done by adding ",tx=bh" or
	",tx=timer" to the "-device virtio-net-pci" commandline option.

	'bh' stands for 'bottom half'; when this is set, packet tx is all done
	in an iothread in the bottom half of the driver. (In libvirt, this
	option is called the more descriptive "iothread".)

	'timer' means that tx work is done in qemu, and if there is more tx
	data than can be sent at the present time, a timer is set before qemu
	moves on to do other things; when the timer fires, another attempt is
	made to send more data. (libvirt retains the name "timer" for this
	option.)

	The resulting difference, according to the qemu developer who added
	the option is:

	    bh makes tx more asynchronous and reduces latency, but potentially
	    causes more processor bandwidth contention since the cpu doing the
	    tx isn't necessarily the cpu where the guest generated the
	    packets.

	Solution

	This patch provides a libvirt domain xml knob to change the option on
	the qemu commandline, by adding a new attribute "txmode" to the
	<driver> element that can be placed inside any <interface> element in
	a domain definition. It's use would be something like this:

	    <interface ...>
	      ...
	      <model type='virtio'/>
	      <driver txmode='iothread'/>
	      ...
	    </interface>

	I chose to put this setting as an attribute to <driver> rather than as
	a sub-element to <tune> because it is specific to the virtio-net
	driver, not something that is generally usable by all network drivers.
	(note that this is the same placement as the "driver name=..."
	attribute used to choose kernel vs. userland backend for the
	virtio-net driver.)

	Actually adding the tx=xxx option to the qemu commandline is only done
	if the version of qemu being used advertises it in the output of

	    qemu -device virtio-net-pci,?

	If a particular txmode is requested in the XML, and the option isn't
	listed in that help output, an UNSUPPORTED_CONFIG error is logged, and
	the domain fails to start.

2011-02-18  Laine Stump  <laine@laine.org>

	Restructure domain struct interface "driver" data for easier expansion
	When the <driver> element (and its "name" attribute) was added to the
	domain XML's interface element, a "backend" enum was simply added to
	the toplevel of the virDomainNetDef struct.

	Ignoring the naming inconsistency ("name" vs. "backend"), this is fine
	when there's only a single item contained in the driver element of the
	XML, but doesn't scale well as we add more attributes that apply to
	the backend of the virtio-net driver, or add attributes applicable to
	other drivers.

	This patch changes virDomainNetDef in two ways:

	1) Rename the item in the struct from "backend" to "name", so that
	   it's the same in the XML and in the struct, hopefully avoiding
	   confusion for someone unfamiliar with the function of the
	   attribute.

	2) Create a "driver" union within virDomainNetDef, and a "virtio"
	   struct in that struct, which contains the "name" enum value.

	3) Move around the virDomainNetParse and virDomainNetFormat functions
	   to allow for simple plugin of new attributes without disturbing
	   existing code. (you'll note that this results in a seemingly
	   redundant if() in the format function, but that will no longer be
	   the case as soon as a 2nd attribute is added).

	In the future, new attributes for the virtio driver backend can be
	added to the "virtio" struct, and any other network device backend that
	needs an attribute will have its own struct added to the "driver"
	union.

	correctly cleaned up. Amongst other things the SELinux
	security label would not be removed, which prevents the VM
	from ever starting again.

	The virDomainIsActive() check at the start of qemudShutdownVMDaemon
	checks for vm->def->id not being -1. By moving the assignment of the
	VM id to the start of qemudStartVMDaemon, we can ensure cleanup will
	occur on failure

	* src/qemu/qemu_driver.c: Move initialization of 'vm->def->id'
	  so that qemudShutdownVMDaemon() will process the shutdown

	xen: Prevent updating device when attaching a device
	When attaching a device that already exists, xend driver updates
	the device with "device_configure", it causes problems (e.g. for
	disk device, 'device_configure' only can be used to update device
	like CDROM), on the other hand, we provide additional API
	(virDomainUpdateDevice) to update device, this fix is to raise up
	errors instead of updating the existed device which is not CDROM
	device.

	Changes from v1 to v2:
	  - allow to update CDROM

	qemu: Fix escape_monitor(escape_shell(command))
	Suspending a VM which contains shell meta characters doesn't work with
	libvirt-0.8.7:
	/var/log/libvirt/qemu/andreas_231-ne\ doch\ nicht.log:
	  sh: -c: line 0: syntax error near unexpected token `doch'
	  sh: -c: line 0: `cat | { dd bs=4096 seek=1 if=/dev/null && dd bs=1048576; }

	Although target="andreas_231-ne doch nicht" contains shell meta
	characters (here: blanks), they are not properly escaped by
	src/qemu/qemu_monitor_{json,text}.c#qemuMonitor{JSON,Text}MigrateToFile()

	First, the filename needs to be properly escaped for the shell, than
	this command line has to be properly escaped for qemu again.

	For this to work, remove the old qemuMonitorEscapeArg() wrapper, rename
	qemuMonitorEscape() to it removing the handling for shell=TRUE, and
	implement a new qemuMonitorEscapeShell() returning strings using single
	quotes.

	Using double quotes or escaping special shell characters with backslashes
	would also be possible, but the set of special characters heavily
	depends on the concrete shell (dsh, bash, zsh) and its setting (history
	expansion, interactive use, ...)

2011-02-11  Daniel P. Berrange  <berrange@redhat.com>

	Imprint all logs with version + package build information
	The logging functions are enhanced so that immediately prior to
	the first log message being printed to any output channel, the
	libvirt package version will be printed.

	eg

	 $ LIBVIRT_DEBUG=1 virsh
	 18:13:28.013: 17536: info : libvirt version: 0.8.7
	 18:13:28.013: 17536: debug : virInitialize:361 : register drivers
	 ...

	The 'configure' script gains two new arguments which can be
	used as

	   --with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10"
	   --with-packager-version="1.fc14"

	to allow distros to append a custom string with package specific
	data.

	The RPM specfile is modified so that it appends the RPM version,
	the build host, the build date and the packager name.

	eg

	 $ LIBVIRT_DEBUG=1 virsh
	 18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
	 18:14:52.086: 17551: debug : virInitialize:361 : register drivers

	Thus when distro packagers receive bug reports they can clearly
	see what version was in use, even if the bug reporter mistakenly
	or intentionally lies about version/builds

	* src/util/logging.c: Output version data prior to first log message
	* libvirt.spec.in: Include RPM release, date, hostname & packager
	* configure.ac: Add --with-packager & --with-packager-version args

	qemu: fix attach-interface regression
	QEMUD_CMD_FLAG_PCI_MULTIBUS should be set in the function
	qemuCapsExtractVersionInfo()

	The flag QEMUD_CMD_FLAG_PCI_MULTIBUS is used in the function
	qemuBuildDeviceAddressStr(). All callers get qemuCmdFlags
	by the function qemuCapsExtractVersionInfo() except that
	testCompareXMLToArgvFiles() in qemuxml2argvtest.c.

	So we should set QEMUD_CMD_FLAG_PCI_MULTIBUS in the function
	qemuCapsExtractVersionInfo() instead of qemuBuildCommandLine()
	because the function qemuBuildCommandLine() does not be called
	when we attach a pci device.

	tests: set QEMUD_CMD_FLAG_PCI_MULTIBUS in testCompareXMLToArgvFiles()

	set QEMUD_CMD_FLAG_PCI_MULTIBUS before calling qemuBuildCommandLine()
	as the flags is not set by qemuCapsExtractVersionInfo().

	Don't use CLONE_NEWUSER for now
	Until now, user namespaces have not done much, but (for that
	reason) have been innocuous to glob in with other CLONE_
	flags.  Upcoming userns development, however, will make tasks
	cloned with CLONE_NEWUSER far more restricted.  In particular,
	for some time they will be unable to access files with anything
	other than the world access perms.

	This patch assumes that noone really needs the user namespaces
	to be enabled.  If that is wrong, then we can try a more
	baroque patch where we create a file owned by a test userid with
	700 perms and, if we can't access it after setuid'ing to that
	userid, then return 0.  Otherwise, assume we are using an
	older, 'harmless' user namespace implementation.

	Comments appreciated.  Is it ok to do this?

	Support booting from hostdev devices

2011-02-04  Jiri Denemark  <jdenemar@redhat.com>

	qemu: Add shortcut for HMP pass through
	Currently users who want to use virDomainQemuMonitorCommand() API or
	it's virsh equivalent has to use the same protocol as libvirt uses for
	communication to qemu. Since the protocol is QMP with current qemu and
	HMP much more usable for humans, one ends up typing something like the
	following:

	    virsh qemu-monitor-command DOM \
	'{"execute":"human-monitor-command","arguments":{"command-line":"info kvm"}}'

	which is not a very convenient way of debugging qemu.

	This patch introduces --hmp option to qemu-monitor-command, which says
	that the provided command is in HMP. If libvirt uses QMP to talk with
	qemu, the command will automatically be converted into QMP. So the
	example above is simplified to just

	    virsh qemu-monitor-command --hmp DOM "info kvm"

	Also the result is converted from

	    {"return":"kvm support: enabled\r\n"}

	to just plain HMP:

	    kvm support: enabled

	If libvirt talks to qemu in HMP, --hmp flag is obviously a noop.

	qemu: avoid double shutdown
	* src/qemu/qemu_driver.c (qemudShutdownVMDaemon): Check that vm is
	still active.
	Reported by Wen Congyang as follows:

	Steps to reproduce this bug:

	1. use gdb to debug libvirtd, and set breakpoint in the function
	   qemuConnectMonitor()
	2. start a vm, and the libvirtd will be stopped in qemuConnectMonitor()
	3. kill -STOP $(cat /var/run/libvirt/qemu/<domain>.pid)
	4. continue to run libvirtd in gdb, and libvirtd will be blocked in the
	   function qemuMonitorSetCapabilities()
	5. kill -9 $(cat /var/run/libvirt/qemu/<domain>.pid)

	Here is log of the qemu:
	=========
	LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin ...
	char device redirected to /dev/pts/3
	2011-01-27 09:38:48.101: shutting down
	2011-01-27 09:41:26.401: shutting down
	=========

	The vm is shut down twice. I do not know whether this behavior has
	side effect, but I think we should shutdown the vm only once.

	Don't sleep in poll() if there is existing SASL decoded data
	In the SASL codepath we typically read far more data off the
	wire than we immediately need. When using a connection from a
	single thread this isn't a problem, since only our reply will
	be pending (or an event we can handle directly). When using a
	connection from multiple threads though, we may read the data
	from replies from other threads. If those replies occur after
	our own reply, they'll not be processed. The other thread will
	then go into poll() and wait for its reply which has already
	been received and decoded. The solution is to set poll() timeout
	to 0 if there is pending SASL data.

2011-01-29  Matthias Bolte  <matthias.bolte@googlemail.com>

	Add VIR_DIV_UP to divide memory or storage request sizes with round up
	Use it in all places where a memory or storage request size is converted
	to a larger granularity. This avoids requesting too small memory or storage
	sizes that could result from the truncation done by a simple division.

	This extends the round up fix in 6002e0406c338668ea0ecbfeb6c1ef20a8b67efe
	to the whole codebase.

	Instead of reporting errors for odd values in the VMX code round them up.

	Update the QEMU Argv tests accordingly as the original memory size 219200
	isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
	it to 219100 and 219136. Use two different values intentionally to make
	sure that rounding up works.

	Update virsh.pod accordingly, as rounding down and rejecting are replaced
	by rounding up.

	Force guest suspend at timeout
	If the memory of guest OS is changed constantly, the live migration
	can not be ended ever for ever.

	We can use the command 'virsh migrate-setmaxdowntime' to control the
	live migration. But the value of maxdowntime is diffcult to calculate
	because it depends on the transfer speed of network and constantly
	changing memroy size. We need a easy way to control the live migration.

	This patch adds the support of forcing guest to suspend at timeout.
	With this patch, when we migrate the guest OS, we can specify a
	timeout. If the live migration timeouts, auto-suspend the guest OS,
	where the migration will complete offline.

	avoid vm to be deleted if qemuConnectMonitor failed
	Steps to reproduce this bug:
	1. service libvirtd start
	2. virsh start <domain>
	3. kill -STOP $(cat /var/run/libvirt/qemu/<domain>.pid)
	4. service libvirtd restart
	5. kill -9 $(cat /var/run/libvirt/qemu/<domain>.pid)

	Then libvirtd will core dump or be in deadlock state.

	Make sure that json is built into libvirt and the version
	of qemu is newer than 0.13.0.

	The reason of libvirtd cores dump is that:
	We add vm->refs when we alloc the memory, and decrease it
	in the function qemuHandleMonitorEOF() in other thread.

	We add vm->refs in the function qemuConnectMonitor() and
	decrease it when the vm is inactive.

	The libvirtd will block in the function qemuMonitorSetCapabilities()
	because the vm is stopped by signal SIGSTOP. Now the vm->refs is 2.

	Then we kill the vm by signal SIGKILL. The function
	qemuMonitorSetCapabilities() failed, and then we will decrease vm->refs
	in the function qemuMonitorClose().
	In another thread, mon->fd is broken and the function
	qemuHandleMonitorEOF() is called.

	If qemuHandleMonitorEOF() decreases vm->refs before qemuConnectMonitor()
	returns, vm->refs will be decrease to 0 and the memory is freed.

	We will call qemudShutdownVMDaemon() as qemuConnectMonitor() failed.
	The memory has been freed, so qemudShutdownVMDaemon() is too dangerous.

	We will reference NULL pointer in the function virDomainConfVMNWFilterTeardown():
	=============
	void
	virDomainConfVMNWFilterTeardown(virDomainObjPtr vm) {
	    int i;

	    if (nwfilterDriver != NULL) {
	        for (i = 0; i < vm->def->nnets; i++)
	            virDomainConfNWFilterTeardown(vm->def->nets[i]);
	    }
	}
	============
	vm->def->nnets is not 0 but vm->def->nets is NULL(We don't set vm->def->nnets
	to 0 when we free vm).

	We should add an extra reference of vm to avoid vm to be deleted if
	qemuConnectMonitor() failed.

	event: fix event-handling allocation crash
	Regression introduced in commit e6b68d7 (Nov 2010).

	Prior to that point, handlesAlloc was always a multiple of
	EVENT_ALLOC_EXTENT (10), and was an int (so even if the subtraction
	had been able to wrap, a negative value would be less than the count
	not try to free the handles array).  But after that point,
	VIR_RESIZE_N made handlesAlloc grow geometrically (with a pattern of
	10, 20, 30, 45 for the handles array) but still freed in multiples of
	EVENT_ALLOC_EXTENT; and the count changed to size_t.  Which means that
	after 31 handles have been created, then 30 handles destroyed,
	handlesAlloc is 5 while handlesCount is 1, and since (size_t)(1 - 5)
	is indeed greater than 1, this then tried to free 10 elements, which
	had the awful effect of nuking the handles array while there were
	still live handles.

	Nuking live handles puts libvirtd in an inconsistent state, and was
	easily reproducible by starting and then stopping 60 faqemu guests.

	* daemon/event.c (virEventCleanupTimeouts, virEventCleanupHandles):
	Avoid integer wrap-around causing us to delete the entire array
	while entries are still active.

	Manually kill gzip if restore fails before starting qemu
	If a guest image is saved in compressed format, and the restore fails
	in some way after the intermediate process used to uncompress the
	image has been started, but before qemu has been started to hook up to
	the uncompressor, libvirt will endlessly wait for the uncompressor to
	finish, but it never will because it's still waiting to have something
	hooked up to drain its output.

	The solution is to close the pipes on both sides of the uncompressor,
	then send a SIGTERM before calling waitpid on it (only if the restore
	has failed, of course).

	Set SELinux context label of pipes used for qemu migration
	This patch is a partial resolution to the following bug:

	   https://bugzilla.redhat.com/show_bug.cgi?id=667756

	(to complete the fix, an updated selinux-policy package is required,
	to add the policy that allows libvirt to set the context of a fifo,
	which was previously not allowed).

	Explanation : When an incoming migration is over a pipe (for example,
	if the image was compressed and is being fed through gzip, or was on a
	root-squash nfs server, so needed to be opened by a child process
	running as a different uid), qemu cannot read it unless the selinux
	context label for the pipe has been set properly.

	The solution is to check the fd used as the source of the migration
	just before passing it to qemu; if it's a fifo (implying that it's a
	pipe), we call the newly added virSecurityManagerSetFDLabel() function
	to set the context properly.

2011-01-26  Laine Stump  <laine@laine.org>

	Add a function to the security driver API that sets the label of an open fd.
	A need was found to set the SELinux context label on an open fd (a
	pipe, as a matter of fact). This patch adds a function to the security
	driver API that will set the label on an open fd to secdef.label. For
	all drivers other than the SELinux driver, it's a NOP. For the SElinux
	driver, it calls fsetfilecon().

	If the return is a failure, it only returns error up to the caller if
	1) the desired label is different from the existing label, 2) the
	destination fd is of a type that supports setting the selinux context,
	and 3) selinux is in enforcing mode. Otherwise it will return
	success. This follows the pattern of the existing function
	SELinuxSetFilecon().

	qemu: sound: Support intel 'ich6' model
	In QEMU, the card itself is a PCI device, but it requires a codec
	(either -device hda-output or -device hda-duplex) to actually output
	sound. Specifying <sound model='ich6'/> gives us -device intel-hda
	-device hda-duplex I think it's important that a simple <sound model='ich6'/>
	sets up a useful codec, to have consistent behavior with all other sound cards.

	This is basically Dan's proposal of

	    <sound model='ich6'>
	        <codec type='output' slot='0'/>
	        <codec type='duplex' slot='3'/>
	    </sound>

	without the codec bits implemented.

	The important thing is to keep a consistent API here, we don't want some
	<sound> devs require tweaking codecs but not others. Steps I see to
	accomplishing this:

	    - every <sound> device has a <codec type='default'/> (unless codecs are
	        manually specified)
	    - <codec type='none'/> is required to specify 'no codecs'
	    - new audio settings like mic=on|off could then be exposed in
	        <sound> or <codec> in a consistent manner for all sound models

	v2:
	    Use model='ich6'

	v3:
	    Use feature detection, from eblake
	    Set codec id, bus, and cad values

	v4:
	    intel-hda isn't supported if -device isn't available

	event: fix event-handling data race
	This bug has been present since before the time that commit

	Dereferencing eventLoop.handles outside the lock risks crashing, since
	any other thread could have reallocated the array in the meantime.

	This provides better security access control than VNC listening on

	Enable tuning of qemu network tap device "sndbuf" size
	This is in response to a request in:

	   https://bugzilla.redhat.com/show_bug.cgi?id=665293

	In short, under heavy load, it's possible for qemu's networking to
	lock up due to the tap device's default 1MB sndbuf being
	inadequate. adding "sndbuf=0" to the qemu commandline -netdevice
	option will alleviate this problem (sndbuf=0 actually sets it to
	0xffffffff).

	Because we must be able to explicitly specify "0" as a value, the
	standard practice of "0 means not specified" won't work here. Instead,
	virDomainNetDef also has a sndbuf_specified, which defaults to 0, but
	is set to 1 if some value was given.

	The sndbuf value is put inside a <tune> element of each <interface> in
	the domain. The intent is that further tunable settings will also be
	placed inside this element.

	     <interface type='network'>
	       ...
	       <tune>
	         <sndbuf>0</sndbuf>
	       ...
	       </tune>
	     </interface>

	Add XML config switch to enable/disable vhost-net support
	This patch is in response to

	  https://bugzilla.redhat.com/show_bug.cgi?id=643050

	The existing libvirt support for the vhost-net backend to the virtio
	network driver happens automatically - if the vhost-net device is
	available, it is always enabled, otherwise the standard userland
	virtio backend is used.

	This patch makes it possible to force whether or not vhost-net is used
	with a bit of XML. Adding a <driver> element to the interface XML, eg:

	     <interface type="network">
	       <model type="virtio"/>
	       <driver name="vhost"/>

	will force use of vhost-net (if it's not available, the domain will
	fail to start). if driver name="qemu", vhost-net will not be used even
	if it is available.

	If there is no <driver name='xxx'/> in the config, libvirt will revert
	to the pre-existing automatic behavior - use vhost-net if it's
	available, and userland backend if vhost-net isn't available.

	Use the new set_password monitor command to set password.
	We try to use that command first when setting a VNC/SPICE password. If
	that doesn't work we fallback to the legacy VNC only password

	Allow an expiry time to be set, if that doesn't work, throw an error
	if they try to use SPICE.

	Change since v1:
	- moved qemuInitGraphicsPasswords to qemu_hotplug, renamed
	  to qemuDomainChangeGraphicsPasswords.
	- updated what looks like a typo (that appears to work anyway) in
	  initial patch from Daniel:
	    - ret = qemuInitGraphicsPasswords(driver, vm,
	    -                                 VIR_DOMAIN_GRAPHICS_TYPE_SPICE,
	    -                                 &vm->def->graphics[0]->data.vnc.auth,
	    -                                 driver->vncPassword);
	    + ret = qemuInitGraphicsPasswords(driver, vm,
	    +                                 VIR_DOMAIN_GRAPHICS_TYPE_SPICE,
	    +                                 &vm->def->graphics[0]->data.spice.auth,

	qemu: Watchdog IB700 is not a PCI device (RHBZ#667091).
	Skip IB700 when assigning PCI slots.

	Note: the I6300ESB watchdog _is_ a PCI device.

	To test this: I applied this patch to libvirt-0.8.3-2.fc14 (rebasing
	it slightly: qemu_command.c didn't exist in that version) and
	installed this on my machine, then tested that I could successfully
	add an ib700 watchdog device to a guest, start the guest, and the
	ib700 was available to the guest.  I also added an i6300esb (PCI)
	watchdog to another guest, and verified that libvirt assigned a PCI
	device to it, that the guest could be started, and that i6300esb was
	present in the guest.

	Note that if you previously had a domain with a ib700 watchdog, it
	would have had an <address type='pci' .../> clause added to it in the
	libvirt configuration.  This patch does not attempt to remove this.
	You cannot start such a domain -- qemu gives an error if you try.
	With this patch you are able to remove the bogus address element
	without libvirt adding it back.

	remote: Don't lose track of events when callbacks are slow
	After the remote driver runs an event callback, it unconditionally disables the
	loop timer, thinking it just flushed every queued event. This doesn't work
	correctly though if an event is queued while a callback is running.

	The events actually aren't being lost, it's just that the event loop didn't
	think there was anything that needed to be dispatched. So all those 'lost
	events' should actually get re-triggered if you manually kick the loop by
	generating a new event (like creating a new guest).

	The solution is to disable the dispatch timer _before_ we invoke any event
	callbacks. Events queued while a callback is running will properly reenable the
	timer.

2011-01-11  Daniel P. Berrange  <berrange@redhat.com>

	Refactor the security drivers to simplify usage
	The current security driver usage requires horrible code like

	    if (driver->securityDriver &&
	        driver->securityDriver->domainSetSecurityHostdevLabel &&
	        driver->securityDriver->domainSetSecurityHostdevLabel(driver->securityDriver,
	                                                              vm, hostdev) < 0)

	This pair of checks for NULL clutters up the code, making the driver
	calls 2 lines longer than they really need to be. The goal of the
	patchset is to change the calling convention to simply

	  if (virSecurityManagerSetHostdevLabel(driver->securityDriver,
	                                        vm, hostdev) < 0)

	The first check for 'driver->securityDriver' being NULL is removed
	by introducing a 'no op' security driver that will always be present
	if no real driver is enabled. This guarentees driver->securityDriver
	!= NULL.

	The second check for 'driver->securityDriver->domainSetSecurityHostdevLabel'
	being non-NULL is hidden in a new abstraction called virSecurityManager.
	This separates the driver callbacks, from main internal API. The addition
	of a virSecurityManager object, that is separate from the virSecurityDriver
	struct also allows for security drivers to carry state / configuration
	information directly. Thus the DAC/Stack drivers from src/qemu which
	used to pull config from 'struct qemud_driver' can now be moved into
	the 'src/security' directory and store their config directly.

	* src/qemu/qemu_conf.h, src/qemu/qemu_driver.c: Update to

	daemon: Fix core dumps if unix_sock_group is set
	Setting unix_sock_group to something else than default "root" in
	/etc/libvirt/libvirtd.conf prevents system libvirtd from dumping core on
	crash. This is because we used setgid(unix_sock_group) before binding to
	/var/run/libvirt/libvirt-sock* and setgid() back to original group.
	However, if a process changes its effective or filesystem group ID, it
	will be forbidden from leaving core dumps unless fs.suid_dumpable sysctl
	is set to something else then 0 (and it is 0 by default).

	Changing socket's group ownership after bind works better. And we can do
	so without introducing a race condition since we loosen access rights by
	changing the group from root to something else.

	bridge: Fix generation of dnsmasq's --dhcp-hostsfile option
	I added a host definition to a network definition:

	<network>
	  <name>Lokal</name>
	  <uuid>2074f379-b82c-423f-9ada-305d8088daaa</uuid>
	  <bridge name='virbr1' stp='on' delay='0' />

	    </dhcp>
	  </ip>
	</network>

	But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get
	added to the dnsmasq command. The patch below fixes it for me.

	qemu: Fix bogus warning about uninitialized saveptr

	Log an error on attempts to add a NAT rule for non-IPv4 addresses
	Although the upper-layer code protected against it, it was possible to
	call iptablesForwardMasquerade() with an IPv6 address and have it
	attempt to add a rule to the MASQUERADE chain of ip6tables (which
	doesn't exist).

	This patch changes that function to check the protocol of the given
	address, generate an error log if it's not IPv4 (AF_INET), and finally
	hardcodes all the family parameters sent down to lower-level functions.

2011-01-06  Laine Stump  <laine@laine.org>

	Improve error reporting when parsing dhcp info for virtual networks
	This is partially in response to

	  https://bugzilla.redhat.com/show_bug.cgi?id=653300

	The crash in that report was coincidentally fixed when we switched
	from using inet_pton() to using virSocketParseAddr(), but the absence
	of an ip address in a dhcp static host definition was still silently
	ignored (and that entry discarded from the saved XML). This patch
	turns that into a logged failure; likewise if the entry has neither a
	mac address nor a name attribute (the entry is useless without at
	least one of those, plus an ip address).

	Since the network name is now pulled into this function in order for
	those error logs to be more informative, the other error messages in
	the function have also been changed to take advantage.

	qemu driver: fix positioning to end of log file
	While doing some testing with Qemu and creating huge logfiles I encountered the case where the VM could not start anymore due to the lseek() to the end of the Qemu VM's log file failing. The patch below fixes the problem by replacing the previously used 'int' with 'off_t'.

	To reproduce this error, you could do the following:

	dd if=/dev/zero of=/var/log/libvirt/qemu/<name of VM>.log bs=1024 count=$((1024*2048))

	and you should get an error like this:

	error: Failed to start domain <name of VM>
	error: Unable to seek to -2147482651 in /var/log/libvirt/qemu/<name of VM>.log: Success

	node_device: udev driver does not handle SR-IOV devices
	The udev driver does not update a PCI device with its SR-IOV capabilities,
	when applicable, the way the hal driver does.  As a result, dumping the

	information.

	Improve virSocketAddrMask[ByPrefix] API
	The original version of these functions would modify the address sent
	in, meaning that the caller would usually need to copy the address
	first. This change makes the original a const, and puts the resulting
	masked address into a new arg (which could point to the same
	virSocketAddr as the original, if the caller really wants to modify
	it).

	This also makes the API consistent with virSocketAddrBroadcast[ByPrefix].

2011-01-01  Laine Stump  <laine@laine.org>

	Set broadcast address for IPv4 addresses on virtual network bridges
	Previously we used ioctl() to set the IP address and netmask of the
	bridges used for virtual networks, and apparently the SIOCSIFNETMASK
	ioctl implicitly set the broadcast address for the interface. The new
	method of using the "ip" command requires broadcast address to be
	explicitly specified though.

	Utility functions to produce an IPv4 broadcast address
	These functions work only for IPv4, becasue IPv6 doesn't have the same
	concept of "broadcast address" as IPv4. They merely OR the inverse of
	the netmask with the given host address, thus turning on all the host
	bits.

	includes major changes in virtual machine and storage medium lookup,
	in RDP server property handling, in session/lock handling and other
	minor areas.

	VirtualBox 4.0 also dropped the old event API and replaced it with a
	completely new one. This is not fixed yet and will be addressed in
	another patch. Therefore, currently the domain events are supported
	for VirtualBox 3.x only.

	Based on initial work from Jean-Baptiste Rouault.

	vbox: Handle different IID representation in Version 2.2 on Windows
	On Windows IID's are represented as GUID by value, instead of nsID
	by reference on non-Windows platforms.

	Patch the vbox_CAPI_v2_2.h header to deal with this difference.

	Rewrite vboxIID abstraction that deals with the different IID
	representations. Add support for the GUID representation. Also unify
	the four context dependent free functions for vboxIIDs

	  vboxIIDUnalloc, vboxIIDFree, vboxIIDUtf8Free, vboxIIDUtf16Free

	into vboxIIDUnalloc that is now safe to be called (even multiple
	times) on a vboxIID independent of the source and context of the
	vboxIID.

	The new vboxIID is designed to be used as a stack allocated variable.
	It has a value member that represents the actual IID value.

	bridge: Fix uninitialized variable

2010-12-24  Laine Stump  <laine@laine.org>

	Replace setuid/setgid/initgroups with virSetUIDGID()
	This patch fixes https://bugzilla.redhat.com/show_bug.cgi?id=664406

	If qemu is run as a different uid, it has been unable to access mode
	0660 files that are owned by a different user, but with a group that
	the qemu is a member of (aside from the one group listed in the passwd
	file), because initgroups() is not being called prior to the
	exec. initgroups will change the group membership of the process (and
	its children) to match the new uid.

	To make this happen, the setregid()/setreuid() code in
	qemuSecurityDACSetProcessLabel has been replaced with a call to
	virSetUIDGID(), which does both of those, plus calls initgroups.

	Similar, but not identical, code in qemudOpenAsUID() has been replaced
	with virSetUIDGID(). This not only consolidates the functionality to a
	single location, but also potentially fixes some as-yet unreported
	bugs.

2010-12-24  Laine Stump  <laine@laine.org>

	new virSetUIDGID() utility function
	virSetUIDGID() sets both the real and effective group and user of the
	process, and additionally calls initgroups() to assure that the
	process joins all the auxiliary groups that the given uid is a member
	of.

	Preserve errno across calls to error reporting functions & VIR_FREE
	There are cases when we want log an error message, and possibly free
	some memory as part of the cleanup, while still preserving errno for a
	caller, but the functions that log errors, and virFree (VIR_FREE) make
	system calls that will clear errno. This patch preserves errno during
	those most basic functions (corresponding to virReportSystemError(),
	virReportOOMError(), networkReportError(), etc, as well as
	virStrError()). It does *not preserve errno across calls to higher
	level items such as virDispatchError(), as it's assumed the caller is
	all finished with any need for errno by the time it dispatches the
	error.

2010-12-24  Laine Stump  <laine@laine.org>

	Run radvd for virtual networks with IPv6 addresses
	Running an instance of the router advertisement daemon (radvd) allows
	guests using the virtual network to automatically acquire an IPv6
	address and default route. Note that acquiring an address only works
	for networks with a prefix length of exactly 64 - radvd is still run
	in other circumstances, and still advertises routes, but autoconf will
	not work because it requires exactly 64 bits of address info from the
	network prefix.

	This patch avoids a race condition with the pidfile by manually
	daemonizing radvd rather than allowing it to daemonize itself, then
	creating our own pidfile (in addition to radvd's own file, which is
	unnecessary, but there is no way to tell radvd to not create it). This
	is accomplished by exec'ing it with "--debug 1" in the commandline,
	and using virCommand's features to fork, create a pidfile, and detach
	from the newly forked process.

	Turn on IPv6 support in the bridge_driver.c virtual network driver
	At this point everything is already in place to make IPv6 happen, we just
	need to add a few rules, remove some checks for IPv4-only, and document
	the changes to the XML on the website.

2010-12-24  Laine Stump  <laine@laine.org>

	Update iptables.c to also support ip6tables.
	All of the iptables functions eventually call down to a single
	bottom-level function, and fortunately, ip6tables syntax (for all the
	args that we use) is identical to iptables format (except the
	addresses), so all we need to do is:

	1) Get an address family down to the lowest level function in each
	   case, either implied through an address, or explicitly when no
	   address is in the parameter list, and

	2) At the lowest level, just decide whether to call "iptables" or
	   "ip6tables" based on the family.

	The location of the ip6tables binary is determined at build time by
	autoconf. If a particular target system happens to not have ip6tables
	installed, any attempts to run it will generate an error, but that
	won't happen unless someone tries to define an IPv6 address for a
	network. This is identical behavior to IPv4 addresses and iptables.

2010-12-24  Laine Stump  <laine@laine.org>

	Support multiple IP addresses on one network in bridge_driver.c
	This patch reorganizes the code in bridge_driver.c to account for the
	concept of a single network with multiple IP addresses, without adding
	in the extra variable of IPv6. A small bit of code has been
	temporarily added that checks all given addresses to verify they are
	IPv4 - this will be removed when full IPv6 support is turned on.

2010-12-24  Laine Stump  <laine@laine.org>

	Change virtual network XML parsing/formatting to support IPv6
	This commit adds support for IPv6 parsing and formatting to the
	virtual network XML parser, including moving around data definitions
	to allow for multiple <ip> elements on a single network, but only
	changes the consumers of this API to accommodate for the changes in
	API/structure, not to add any actual IPv6 functionality. That will
	come in a later patch - this patch attempts to maintain the same final
	functionality in both drivers that use the network XML parser - vbox
	and "bridge" (the Linux bridge-based driver used by the qemu
	hypervisor driver).

	* src/libvirt_private.syms: Add new private API functions.
	* src/conf/network_conf.[ch]: Change C data structure and
	  parsing/formatting.
	* src/network/bridge_driver.c: Update to use new parser/formatter.
	* src/vbox/vbox_tmpl.c: update to use new parser/formatter
	* docs/schemas/network.rng: changes to the schema -
	  * there can now be more than one <ip> element.
	  * ip address is now an ip-addr (ipv4 or ipv6) rather than ipv4-addr
	  * new optional "prefix" attribute that can be used in place of "netmask"
	  * new optional "family" attribute - "ipv4" or "ipv6"
	    (will default to ipv4)
	  * define data types for the above
	* tests/networkxml2xml(in|out)/nat-network.xml: add multiple <ip> elements
	  (including IPv6) to a single network definition to verify they are being
	  correctly parsed and formatted.

2010-12-24  Laine Stump  <laine@laine.org>

	make the <dhcp> element optional in network.rng
	In practice this has always been optional, but the RNG has shown it as
	mandatory, and since all the examples for make check had it, it was
	never noticed. One of the existing test cases has been changed to
	check for this.

	I also noticed that the dhcp/host/ip was still defined as <text/>,
	but should really be <ref name='ipv4-addr'/>

2010-12-24  Laine Stump  <laine@laine.org>

	Replace brSetInetAddress/brSetInetNetmask with brAddInetAddress
	brSetInetAddress can only set a single IP address on the bridge, and
	uses a method (ioctl(SIOCSETIFADDR)) that only works for IPv4. Replace
	it and brSetInetNetmask with a single function that uses the external
	"ip addr add" command to add an address/prefix to the interface - this
	supports IPv6, and allows adding multiple addresses to the interface.

	Although it isn't currently used in the code, we also add a
	brDelInetAddress for completeness' sake.

	Also, while we're modifying bridge.c, we change brSetForwardDelay and
	brSetEnableSTP to use the new virCommand API rather than the
	deprecated virRun, and also log an error message in bridge_driver.c if
	either of those fail (previously the failure would be completely
	silent).

2010-12-24  Laine Stump  <laine@laine.org>

	Make virtual network netmasks optional
	When a netmask isn't specified for an IPv4 address, one can be implied
	based on what network class range the address is in. The
	virNetworkDefPrefix function does this for us, so netmask isn't
	required.

2010-12-24  Laine Stump  <laine@laine.org>

	Pass prefix rather than netmask into iptables functions
	IPv6 will use prefix exclusively, and IPv4 will also optionally be
	able to use it, and the iptables functions really need a prefix
	anyway, so use the new virNetworkDefPrefix() function to send prefixes
	into iptables functions instead of netmasks.

	Also, in a couple places where a netmask is actually needed, use the
	new private API function for it rather than getting it directly. This
	will allow for cases where no netmask or prefix is specified (it
	returns the default for the current class of network.)

2010-12-24  Laine Stump  <laine@laine.org>

	Consistently return 0 on success, -1 on failure in bridge_driver.c
	Some functions in this file were returning 1 on success and 0 on
	failure, and others were returning 0 on success and -1 on
	failure. Switch them all to return the libvirt-preferred 0/-1.

	Fix logging of failed iptables commands
	The functions in iptables.c all return -1 on failure, but all their
	callers (which all happen to be in bridge_driver.c) assume that they
	are returning an errno, and the logging is done accordingly. This
	patch fixes all the error checking and logging to assume < 0 is an
	error, and nothing else.

2010-12-24  Laine Stump  <laine@laine.org>

	New virNetworkDef utility functions
	Later patches will add the possibility to define a network's netmask
	as a prefix (0-32, or 0-128 in the case of IPv6). To make it easier to
	deal with definition of both kinds (prefix or netmask), add two new
	functions:

	virNetworkDefNetmask: return a copy of the netmask into a
	virSocketAddr. If no netmask was specified in the XML, create a
	default netmask based on the network class of the virNetworkDef's IP
	address.

	virNetworkDefPrefix: return the netmask as numeric prefix (or the
	default prefix for the network class of the virNetworkDef's IP
	address, if no netmask was specified in the XML)

2010-12-24  Laine Stump  <laine@laine.org>

	New virSocketAddr utility functions
	virSocketPrefixToNetmask: Given a 'prefix', which is the number of 1
	bits in a netmask, fill in a virSocketAddr object with a netmask as an
	IP address (IPv6 or IPv4).

	virSocketAddrMask: Mask off the host bits in one virSocketAddr
	according to the netmask in another virSocketAddr.

	virSocketAddrMaskByPrefix, Mask off the host bits in a virSocketAddr

	qemu: Reparent children when deleting a snapshot
	Shorten qemuDomainSnapshotWriteSnapshotMetadata function name
	and make it take a snapshot pointer instead of dealing with
	the current snapshot. Update other functions accordingly.

	Add a qemuDomainSnapshotReparentChildren hash iterator to
	reparent the children of a snapshot that is being deleted. Use
	qemuDomainSnapshotWriteMetadata to write updated metadata
	to disk.

	This fixes a problem where outdated parent information breaks

	Set bitmap size when allocating a bitmap
	I began noticing a race when reserving VNC ports as described here

	https://www.redhat.com/archives/libvir-list/2010-November/msg00379.html

	Turns out that we were not initializing the size field of bitmap
	struct when allocating the bitmap.  This subsequently caused
	virBitmapSetBit() to fail since bitmap->size is 0, hence we never
	actually reserved the port.

	cpu: Unify CPUID data structures
	So far, CPUID data were stored in two different data structures. First
	of them was a structure allowing direct access for CPUID data according

	from one type to the other and back again or implementing similar
	functionality for both data structures.

	The patch leaves only the direct access structure. This makes the code

	qemu: Introduce two new job types
	Currently, all of domain "save/dump/managed save/migration"
	use the same function "qemudDomainWaitForMigrationComplete"
	to wait the job finished, but the error messages are all
	about "migration", e.g. when a domain saving job is canceled
	by user, "migration was cancled by client" will be throwed as
	an error message, which will be confused for user.

	As a solution, intoduce two new job types(QEMU_JOB_SAVE,
	QEMU_JOB_DUMP), and set "priv->jobActive" to "QEMU_JOB_SAVE"
	before saving, to "QEMU_JOB_DUMP" before dumping, so that we
	could get the real job type in
	"qemudDomainWaitForMigrationComplete", and give more clear
	message further.

	And as It's not important to figure out what's the exact job
	is in the DEBUG and WARN log, also we don't need translated
	string in logs, simply repace "migration" with "job" in some
	statements.

	Convert dhcpStartDhcpDaemon from virRun to virCommand
	This is pretty straightforward - even though dnsmasq gets daemonized
	and uses a pid file, those things are both handled by the dnsmasq
	binary itself. And libvirt doesn't need any of the output of the
	dnsmasq command either, so we just setup the args and call
	virRun(). Mainly it was just a (mostly) mechanical job of replacing
	the APPEND_ARG() macro (and some other *printfs()) with
	virCommandAddArg*().

	Instead of just reporting that a task failed get the
	localized message from the TaskInfo error and include
	it in the reported error message.

	Implement minimal deserialization support for the
	MethodFault type in order to obtain the actual fault
	type.

	For example, this changes the reported error message

	qemu: Distinguish between domain shutdown and crash
	When we get an EOF event on monitor connection, it may be a result of
	either crash or graceful shutdown. QEMU which supports async events
	(i.e., we are talking to it using JSON monitor) emits SHUTDOWN event on
	graceful shutdown. In case we don't get this event by the time monitor
	connection is closed, we assume the associated domain crashed.

	qemu: call drive_del in DetachPciDiskDevice
	Currently libvirt doesn't confirm whether the guest has responded to the
	disk removal request.  In some cases this can leave the guest with
	continued access to the device while the mgmt layer believes that it has
	been removed.  With a recent qemu monitor command[1] we can
	deterministically revoke a guests access to the disk (on the QEMU side)
	to ensure no futher access is permitted.

	This patch adds support for the drive_del() command and introduces it
	in the disk removal paths.  If the guest is running in a QEMU without this
	command we currently explicitly check for unknown command/CommandNotFound
	and log the issue.

	If QEMU supports the command we issue the drive_del command after we attempt
	to remove the device.  The guest may respond and remove the block device
	before we get to attempt to call drive_del.  In that case, we explicitly check
	for 'Device not found' from the monitor indicating that the target drive
	was auto-deleted upon guest responds to the device removal notification.

	Changes since v2:
	 - use VIR_ERROR to report when unplug command not found
	Changes since v1:

	qemu: avoid adding "" in smbios arguments
	The log lists things like -smbios type=1,vendor="Red Hat", which
	is great for shell parsing, but not so great when you realize that
	execve() then passes those literal "" on as part of the command
	line argument, such that qemu sets SMBIOS with extra literal quotes.

	The eventual addition of virCommand is needed before we have the API
	to shell-quote a string representation of a command line, so that the
	log can still be pasted into a shell, but without inserting extra
	bytes into the execve() arguments.

	* src/qemu/qemu_conf.c (qemuBuildSmbiosBiosStr)
	(qemuBuildSmbiosSystemStr): Qemu doesn't like quotes around uuid
	arguments, and the remaining quotes are passed literally to

	quotes makes the log harder to parse, but that can be fixed later
	with virCommand improvements.
	* tests/qemuxml2argvdata/qemuxml2argv-smbios.args: 'Fix' test; it
	will need fixing again once virCommand learns how to shell-quote a
	potential command line.

	tests: Support for faking emulator in qemuxml2argv
	This patch allows for using custom scripts instead of /usr/bin/qemu
	emulator in domain XML. To do so, one would specify relative path to the
	custom script in <emulator/>. The path needs to be relative to
	qemuxml2argvdata directory and it will be transparently made absolute in
	runtime. The expected command line needs to contain the exact relative
	path as was used in domain XML.

	The problem is RelaxNG schema for domain XML only allows for absolute
	path within <emulator/>. To workaround it, an extra '/' must be added at
	the beginning of the path. That is, instead of "./qemu.sh" or
	"../emulator/qemu.sh" one would use "/./qemu.sh" or
	"/../emulator/qemu.sh". The extra slash is removed before further
	processing. I don't like this workaround, it's very ugly but it's the
	best option I was able to come up with. Relaxing domain XML schema is
	not an option IMO.

	802.1Qbg: use pre-associate state at beginning of inc. migr
	This patch introduces the usage of the pre-associate state of the IEEE 802.1Qbg standard on incoming VM migration on the target host. It is in response to bugzilla entry 632750.

	https://bugzilla.redhat.com/show_bug.cgi?id=632750

	For being able to differentiate the exact reason as to why a macvtap device is being created, either due to a VM creation or an incoming VM migration, I needed to pass that reason as a parameter from wherever qemudStartVMDaemon is being called in order to determine whether to send an ASSOCIATE (VM creation) or a PRE-ASSOCIATE (incoming VM migration) towards lldpad.

	I am also fixing a problem with the virsh domainxml-to-native call on the way.

	Gerhard successfully tested the patch with a recent blade network 802.1Qbg-compliant switch.

	The patch should not have any side-effects on the 802.1Qbh support in libvirt, but Roopa (cc'ed) may want to verify this.

2010-11-25  Jiri Denemark  <jdenemar@redhat.com>

	Fix host CPU counting on unusual NUMA topologies
	The nodeinfo structure includes

	    nodes   : the number of NUMA cell, 1 for uniform mem access
	    sockets : number of CPU socket per node
	    cores   : number of core per socket
	    threads : number of threads per core

	which does not work well for NUMA topologies where each node does not
	consist of integral number of CPU sockets.

	We also have VIR_NODEINFO_MAXCPUS macro in public libvirt.h which
	computes maximum number of CPUs as (nodes * sockets * cores * threads).

	As a result, we can't just change sockets to report total number of
	sockets instead of sockets per node. This would probably be the easiest
	since I doubt anyone is using the field directly. But because of the
	macro, some apps might be using sockets indirectly.

	This patch leaves sockets to be the number of CPU sockets per node (and
	fixes qemu driver to comply with this) on machines where sockets can be
	divided by nodes. If we can't divide sockets by nodes, we behave as if
	there was just one NUMA node containing all sockets. Apps interested in
	NUMA should consult capabilities XML, which is what they probably do
	anyway.

	This way, the only case in which apps that care about NUMA may break is
	on machines with funky NUMA topology. And there is a chance libvirt
	wasn't able to start any guests on those machines anyway (although it
	depends on the topology, total number of CPUs and kernel version).
	Nothing changes at all for apps that don't care about NUMA.

	security, storage: plug memory leaks for security_context_t
	security_context_t happens to be a typedef for char*, and happens to
	begin with a string usable as a raw context string.  But in reality,
	it is an opaque type that may or may not have additional information

	include pointers that can only be freed via freecon().

	Proof is from this valgrind run of daemon/libvirtd:

	Always close drivers when a virConnectPtr is released
	virConnectClose calls virUnrefConnect which in turn closes
	all open drivers when the refcount of that connection dropped
	to zero. This works fine when you free all other objects that
	hold a ref to the connection before you close it, because in
	this case virUnrefConnect is the one that removes the last
	ref to the connection.

	But it doesn't work when you close the connection first before
	freeing the other objects. This is because the other virUnref*
	functions call virReleaseConnect when they detect that the
	connection's refcount dropped to zero. In this case another
	virUnref* function (different from virUnrefConnect) removes the
	last ref to the connection. This results in not closing the
	open drivers and leaking things that should have been cleaned
	up in the driver close functions.

	To fix this move the driver close calls to virReleaseConnect.

	remote: Fix TLS transport on Windows

	into file descriptor based ones that are used in libvirt.

	Even though GnuTLS is using gnulib too, it explicitly doesn't use
	gnulib's replacement functions on Windows. By default GnuTLS uses the
	SOCKET handle based send() and recv(). This makes gnutls_handshake()
	fail internally with a WSAENOTSOCK error because libvirt passes a
	file descriptor; GnuTLS needs the SOCKET handle.

	To avoid this mismatch make sure that GnuTLS uses gnulib's replacment

	Improve SCSI volume name generation

	pools is dynamically allocated by the kernel at time of login.
	This changes the name to be 'unit:0:0:1', ie removes the leading

	Remove bogus port handling code in virsh
	The "find-storage-pool-sources-as" command takes two arguments,
	a hostname and a port number. For some reason the code would
	also then look for a port number appended to the hostname
	string by searching for ':'. This totally breaks if the user
	gives an IPv6 address, and is redundant, since you can already
	provide a port as a separate argument

	The code generating XML for storage pool source discovery is

	parameters.

	* tools/virsh.c: Refactor XML generator

2010-11-23  Daniel P. Berrange  <berrange@redhat.com>

	Add support for iSCSI target auto-discovery
	Since the previous patch added support for parsing the output of
	the 'sendtargets' command, it is now trivial to support the
	storage pool discovery API.

	Given a hostname and optional portnumber and initiator IQN,
	the code can return a full list of storage pool source docs,
	each one representing a iSCSI target.

	* src/storage/storage_backend_iscsi.c: Wire up target
	  auto-discovery

2010-11-23  Daniel P. Berrange  <berrange@redhat.com>

	Stop iSCSI targets automatically logging back in after logout
	The Linux iSCSI initiator toolchain has the dubious feature that
	if you ever run the 'sendtargets' command to merely query what
	targets are available from a server, the results will be recorded
	in /var/lib/iscsi. Any time the '/etc/init.d/iscsi' script runs
	in the future, it will then automatically login to all those
	targets. /etc/init.d/iscsi is automatically run whenever a NIC
	comes online.

	So from the moment you ask a server what targets are available,
	your client will forever more automatically try to login to all
	targets without ever asking if you actually want it todo this.

	To stop this stupid behaviour, we need to run

	  iscsiadm --portal $PORTAL --target $TARGET
	   --op update --name node.startup --value manual

	For every target on the server.

	* src/storage/storage_backend_iscsi.c: Disable automatic login
	  for targets found as a result of a 'sendtargets' command

	Refactor iSCSI driver code to facilitate future changes
	The following series of patches are adding significant
	extra functionality to the iSCSI driver. THe current
	internal helper methods are not sufficiently flexible
	to cope with these changes. This patch refactors the
	code to avoid needing to have a virStoragePoolObjPtr
	instance as a parameter, instead passing individual
	target, portal and initiatoriqn parameters.

	It also removes hardcoding of port 3260 in the portal
	address, instead using the XML value if any.

	Don't catch SIGCHLD in libvirtd
	libvirtd no longer deals with SIGCHLD in its signal handler
	since the QEMU driver switched to always daemonize processes.
	Thus remove the sigaction for it, to avoid warning log
	messages

	* daemon/libvirtd.c: Don't catch SIGCHLD

	Ensure logfile isn't truncated by shutdown message.
	When running non-root, the QEMU log file is usually opened with
	truncation, since there is no logrotate for non-root usage.
	This means that when libvirt logs the shutdown timestamp, the
	log is accidentally truncated

	* src/qemu/qemu_driver.c: Never truncate log file with shutdown
	  message

2010-11-23  Daniel P. Berrange  <berrange@redhat.com>

	Remove trailing ':' from timestamp

2010-11-23  Daniel P. Berrange  <berrange@redhat.com>

	Log all errors at level INFO to stop polluting syslog
	Everytime a public API returns an error, libvirtd pollutes

	qemu: setvcpus: Save config changes to disk
	Currently changes to the persistent config aren't flushed to disk, meaning
	they are lost if the domain is redefined or libvirtd is restarted.

2010-11-23  Cole Robinson  <crobinso@redhat.com>

	qemu: setvcpus: Simplify altering the persistent config
	Do this by adding a helper function to get the persistent domain config. This
	should be useful for other functions that may eventually want to alter
	the persistent domain config (attach/detach device). Also make similar changes
	to the test drivers setvcpus command.

	A caveat is that the function will return the running config for a transient
	domain, rather than error. This simplifies callers, as long as they use
	other methods to ensure the guest is persistent.

2010-11-23  Cole Robinson  <crobinso@redhat.com>

	qemu: setvcpus: Fix maxvcpus check
	Doing 'virsh setvcpus $vm --config 10' doesn't check the value against the

	Also make a similar change to the test driver.

	conf: domain: Improve vcpus validation reporting

2010-11-23  Cole Robinson  <crobinso@redhat.com>

	Make state driver device hotplug/update actually transient
	The current semantics of non-persistent hotplug/update are confusing: the
	changes will persist as long as the in memory domain definition isn't
	overwritten. This means hotplug changes stay around until the domain is
	redefined or libvirtd is restarted.

	Call virDomainObjSetDefTransient at VM startup, so that we properly discard
	hotplug changes when the VM is shutdown.

2010-11-23  Cole Robinson  <crobinso@redhat.com>

	domain_conf: Add virDomainObjSetDefTransient
	This function sets the running domain definition as transient, by reparsing
	the persistent config and assigning it to newDef. This ensures that any
	changes made to the running definition and not the persistent config are
	discarded when the VM is shutdown.

	xend: Escape reserved sexpr characters
	If we don't escape ' or \ xend can't parse the generated sexpr. This
	might over apply the EscapeSexpr routine, but it shouldn't hurt.

	buf: Simplify virBufferEscapeString
	We are about to copy this function, so clean it up before we do.

	xend: urlencode: Properly escape '&'
	Since we send the sexpr to xend via HTTP, we need to properly escape
	'&'

	conf: Fix parsing python style triple quotes
	An incorrect check broke matching the closing set of quotes. Update
	tests to cover this case for XM config files.

	conf: Convert ParseString to use STRPREFIX

	Allow probing of image formats without version information
	Disk image formats that wish to opt-out of version validation are supposed to
	set versionOffset to -1 in their fileTypeInfo entry.

	By unconditionally returning False for these formats,
	virStorageFileMatchesVersion() incorrectly reports a version mismatch when the
	test was actually skipped.  The correct behavior is to return True so these

	maint: tighten strncmp syntax check
	Using 'int ret = strcmp(a, b)' in a qsort function is a valid use of
	str[n]cmp that should _not_ be turned to STREQ, but it was falling
	foul of our specific syntax-check.  Meanwhile, gnulib's maint.mk

	calls bindtextdomain(), but this is insufficient without the

	in this patch doesn't hurt, but serves as a good example for other

	replace last instances of close()
	I am replacing the last instances of close() I found with VIR_CLOSE() / VIR_FORCE_CLOSE respectively.

	The first part patches virsh, which I missed out on previously.

	The 2nd patch I had left out intentionally to look at it more carefully:
	The 'closed' variable could be easily removed since it wasn't used anywhere else. The possible race condition that could result from the filedescriptor being closed and not set to -1 (and possibly let us write into 'something' totally different if the fd was allocated by another thread) seems to be prevented by the qemuMonitorLock() already placed around the code that reads from or writes to the fd. So the change of this code as shown in the patch should not have any side-effects.

	Most of the files are opened in read-only mode, so usage of
	VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write
	mode already had the fclose()<  0 check and I converted those to
	VIR_FCLOSE()<  0.

	I did not find occurrences of possible double-closed files on the way.

	Do a better job of validating IP and MAC addresses in network.rng

	ignore SELinuxSetFilecon error in SELinuxSetSecurityFileLabel if on nfs
	If virDomainAttachDevice() was called with an image that was located
	on a root-squashed NFS server, and in a directory that was unreadable
	by root on the machine running libvirtd, the attach would fail due to
	an attempt to change the selinux label of the image with EACCES (which
	isn't covered as an ignore case in SELinuxSetFilecon())

	NFS doesn't support SELinux labelling anyway, so we mimic the failure
	handling of commit 93a18bbafaf11729d3ca1241e11bee133d77fa77, which
	just ignores the errors if the target is on an NFS filesystem (in
	SELinuxSetSecurityAllLabel() only, though.)

	This can be seen as a follow-on to commit
	347d266c51705f4987fa5ce2a0ecb314ed8745ce, which ignores file open
	failures of files on NFS that occur directly in

	This adds supported for the stream callbacks and non-blocking

	Allow non-file disk backingStores
	I am trying to use a qcow image with libvirt where the backing 'file' is a
	qemu-nbd server.  Unfortunately virDomainDiskDefForeachPath() assumes that
	backingStore is always a real file so something like 'nbd:0:3333' is rejected
	because a file with that name cannot be accessed.  Note that I am not worried
	about directly using nbd images.  That would require a new disk type with XML
	markup, etc.  I only want it to be permitted as a backingStore

	The following patch implements danpb's suggestion:
	> I think I'm inclined to push the logic for skipping NBD one stage higher.
	> I'd rather expect virStorageFileGetMetadata() to return all backing
	> stores, even if not files. The virDomainDiskDefForeachPath() method
	> should definitely ignore non-file backing stores though.
	>
	> So what I'm thinking is to extend the virStorageFileMetadata struct and
	> just add a 'bool isFile' field to it. Default this field to true, unless
	> you see the prefix of nbd: in which case set it to false. The
	> virDomainDiskDefForeachPath() method can then skip over any backing
	> store with isFile == false

	Add a new test for sysinfo and smbios handling

2010-11-08  Daniel Veillard  <veillard@redhat.com>

	Add sysinfo/smbios support to the QEmu driver
	The patch is based on the possiblity in the QEmu command line to
	add -smbios options allowing to override the default values picked
	by QEmu. We need to detect this first from QEmu help output.
	If the domain is defined with smbios to be inherited from host
	then we pass the values coming from the Host own SMBIOS, but
	if the domain is defined with smbios to come from sysinfo, we
	use the ones coming from the domain definition.

	* src/qemu/qemu_conf.h: add the QEMUD_CMD_FLAG_SMBIOS_TYPE enum
	  value
	* src/qemu/qemu_conf.c: scan the help output for the smbios support,
	  and if available add support based on the domain definitions,
	  and host data
	* tests/qemuhelptest.c: add the new enum in the outputs

	macvtap: libvirtd forgot macvtap dev name when restarted
	During a shutdown/restart cycle libvirtd forgot the macvtap device name that it had created on behalf of a VM so that a stale macvtap device remained on the host when the VM terminated. Libvirtd has to actively tear down a macvtap device and it uses its name for identifying which device to tear down.

	The solution is to not blank out the <target dev='...'/> completely, but only blank it out on VMs that are not active. So, if a VM is active, the device name makes it into the XML and is also being parsed. If a VM is not active, the device name is discarded.

	Fix virPipeReadUntilEOF on more than 1024 bytes of data
	virPipeReadUntilEOF is used to read the stdout of exec'ed
	and this could fail to capture the full output and read only
	1024 bytes.
	  The problem is that this is based on a poll loop, and in the
	loop we read at most 1024 bytes per file descriptor, but we also
	note in the loop if poll indicates that the process won't output
	more than that on that fd by setting finished[i] = 1.
	  The simplest way is that if we read a full buffer make sure
	finished[i] is still 0 because we will need another pass in the
	loop.

	qemu: check compression program availability of virsh save and dump

2010-10-30  KAMEZAWA Hiroyuki  <kamezawa.hiroyu@jp.fujitsu.com>

	add compression support for "virsh dump"
	Add dump_image_format[] to qemu.conf and support compressed dump
	at virsh dump. coredump compression is important for saving disk space
	in an environment where multiple guests run.

	In general, "disk space for dump" is specially allocated and will be
	a dead space in the system. It's used only at emergency. So, it's better
	to have both of save_image_format and dump_image_format. "save" is done
	in scheduled manner with enough calculated disk space for it.

	This code reuses some of save_image_format[] and supports the same format.

	Changelog:
	 - modified libvirtd_qemu.aug
	 - modified test_libvirtd_qemu.aug
	 - fixed error handling of qemudSaveCompressionTypeFromString()

	Avoid squashing errors during network startup cleanup path
	When failing to start a virtual network, we have to cleanup,
	tearing down any iptables rules. If the iptables rules were
	not present yet though, this raises an error, which squashes
	the original error we were handling.

	* src/network/bridge_driver.c: When failing to start a virtual
	  network, don't squash the original error in cleanup

	Fix formatting of network address in iptables helpers

	Convert virNetwork to use virSocketAddr everywhere
	Instead of storing the IP address string in virNetwork related
	structs, store the parsed virSocketAddr. This will make it
	easier to add IPv6 support in the future, by letting driver
	code directly check what address family is present

	* src/conf/network_conf.c, src/conf/network_conf.h,
	  src/network/bridge_driver.c: Convert to use virSocketAddr
	  in virNetwork, instead of char *.

	* daemon/libvirtd.c: Include socket address in client
	  connect/disconnect probes

	Add dtrace static probes in libvirtd
	Adds initial support for dtrace static probes in libvirtd
	daemon, assuming use of systemtap dtrace compat shim on
	Linux. The probes are inserted for network client connect,
	disconnect, TLS handshake states and authentication protocol
	states.

	This can be tested by running the xample program and then
	attempting to connect with any libvirt client (virsh,
	virt-manager, etc).

	 # stap examples/systemtap/client.stp
	  Client fd=44 connected readonly=0
	  Client fd=44 auth polkit deny pid:24997,uid:500
	  Client fd=44 disconnected
	  Client fd=46 connected readonly=1
	  Client fd=46 auth sasl allow test
	  Client fd=46 disconnected

	The libvirtd.stp file should also really not be required,
	since it is duplicated info that is already available in
	the main probes.d definition file. A script to autogenerate
	the .stp file is needed, either in libvirtd tree, or better
	as part of systemtap itself.

	* Makefile.am: Add examples/systemtap subdir

	Ban use of all inet_* functions
	All the inet_* functions can be replaced with calls to the
	virSocket APIs. Since many of the inet_* funtions are unsafe,
	and the remainder are obsolete, forbid all future use of them
	in libvirt.

	* Makefile.nonreentrant: Ban use of inet_*

2010-10-22  Daniel P. Berrange  <berrange@redhat.com>

	Remove all use of inet_pton and inet_ntop
	The  inet_pton and inet_ntop functions are obsolete, replaced
	by getaddrinfo+getnameinfo with the AI_NUMERICHOST flag set.
	These can be accessed via the virSocket APIs.

	The bridge.c code had methods for fetching the IP address of
	a bridge which used inet_ntop. Aside from the use of inet_ntop
	these methods are broken, because a NIC can have multiple
	addresses and this only returns one address. Since the methods
	are never used, just remove them.

	* src/conf/network_conf.c, src/nwfilter/nwfilter_learnipaddr.c:
	  Replace inet_pton and inet_ntop with virSocket APIs
	* src/util/bridge.c, src/util/bridge.h: Remove unused methods

	Fix error reporting for virSocketParse
	The virSocketParse method was not doing any error reporting

	* src/conf/domain_conf.c, src/conf/network_conf.c,

2010-10-22  Daniel P. Berrange  <berrange@redhat.com>

	Expand virSocketFormat to be more flexible
	The getnameinfo() function is more flexible than inet_ntop()
	avoiding the need to if/else the code based on socket family.
	Also make it support UNIX socket addrs and allow inclusion
	of a port (service) address. Finally do proper error reporting
	via normal APIs.

	* src/conf/domain_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c,
	  src/qemu/qemu_conf.c: Fix error handling with virSocketFormat

2010-10-22  Daniel P. Berrange  <berrange@redhat.com>

	Remove pointless nwIPAddress struct & void *casts
	The nwIPAddress was simply a wrapper about virSocketAddr.
	Just use the latter directly, removing all the extra field

	void * and then immediately back to strong types.

	* src/conf/nwfilter_conf.h: Remove nwIPAddress
	* src/conf/nwfilter_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c:

2010-10-22  Daniel P. Berrange  <berrange@redhat.com>

	Fix passing of address family to virSocketParseAddr
	The virSocketParseAddr function was accepting any AF_* constant
	and using that to set the ai_flags field in struct addrinfo.
	This is invalid, since address families must go in the ai_family
	field of the struct.

	* src/util/network.c: Fix handling of address family
	* src/conf/network_conf.c, src/network/bridge_driver.c: Pass
	  AF_UNSPEC instead of relying on it being 0.

2010-10-22  Daniel P. Berrange  <berrange@redhat.com>

	Include length with virSocketAddr data
	Some operations on socket addresses need to know the length of
	the sockaddr struct for the particular address family. This
	info was being discarded when passing around virSocketAddr
	instances. Turn it from a union into a struct containing
	union+socklen_t fields, so length is always kept around.

	* src/util/network.h: Add socklen_t field to virSocketAddr
	* src/util/network.c, src/network/bridge_driver.c,
	  src/conf/domain_conf.c: Update to take account of new
	  struct definition.

2010-10-22  Daniel P. Berrange  <berrange@redhat.com>

	Remove useless code in error path of getnameinfo()
	If getnameinfo() with NI_NUMERICHOST set fails, there are no

	in the getnameinfo() error path.

	* daemon/remote.c, src/remote/remote_driver.c: Remove
	  calls to inet_ntop

2010-10-20  Daniel P. Berrange  <berrange@redhat.com>

	Fix symbol exports & remove duplicated libvirt_util.la linkage
	The libvirt_util.la library was mistakenly linked into libvirtd
	directly. Since libvirt_util.la is already linked to libvirt.so,
	this resulted in libvirtd getting two copies of the code and
	more critically 2 copies of static global variables.

	Testing in turn exposed a issue with loadable modules. The
	gnulib replacement functions are not exported to loadable
	modules. Rather than trying to figure out the name sof all
	gnulib functions & export them, just linkage all loadable
	modules against libgnu.la statically.

	* daemon/Makefile.am: Remove linkage of libvirt_util.la
	  and libvirt_driver.la
	* src/Makefile.am: Link driver modules against libgnu.la
	* src/libvirt.c: Don't try to load modules which were

	Audit SELinux label assignment.
	A more natural auditing point would perhaps be
	SELinuxSetSecurityProcessLabel, but this happens in the child after root
	permissions are dropped, so the kernel would refuse the audit record.

2010-10-20  Miloslav Trmač  <mitr@redhat.com>

	Audit VM start/stop/suspend/resume
	Most operations are audited at the libvirtd level; auditing in
	src/libvirt.c would result in two audit entries per operation (one in
	the client, one in libvirtd).

	The only exception is a domain stopping of its own will (e.g. because
	the user clicks on "shutdown" inside the interface).  There can often be
	no client connected at the time the domain stops, so libvirtd does not
	have any virConnectPtr object on which to attach an event watch.  This
	patch therefore adds auditing directly inside the qemu driver (other
	drivers are not supported).

2010-10-20  Daniel P. Berrange  <berrange@redhat.com>

	Basic framework for auditing integration
	Integrate with libaudit.so for auditing of important operations.
	libvirtd gains a couple of config entries for auditing. By
	default it will enable auditing, if its enabled on the host.
	It can be configured to force exit if auditing is disabled
	on the host. It will can also send audit messages via libvirt
	internal logging API

	Places requiring audit reporting can use the VIR_AUDIT
	macro to report data. This is a no-op unless auditing is
	enabled

	* autobuild.sh, mingw32-libvirt.spec.in: Disable audit
	  on mingw
	* configure.ac: Add check for libaudit
	* daemon/libvirtd.aug, daemon/libvirtd.conf,

	qemu: let qemu group look below /var/lib/libvirt/qemu/
	Vdsm needs to communicate with its guest agent via unix domain socket,
	which qemu creates due to the following domain xml device:

	    <channel type='unix'>
	      <target type='virtio' name='com.redhat.rhevm.vdsm'/>
	      <source mode='bind' path='/var/lib/libvirt/qemu/channels/fcp-xp-1.com.redhat.rhevm.vdsm'/>
	    </channel>

	The location of the socket below /var/lib/libvirt/qemu/channels makes
	sense, to humans and selinux policy alike. However, that socket should
	be accessible to vdsm, too.

	Due to other (storage) reasons, vdsm is to join the "qemu" group. With
	this patch, vdsm can look below /var/lib/libvirt/qemu and connect to the
	socket.

	The socket itself should be chmod'ed to allow qemu group read/write, but
	that's for another project.

	did previously not cut off existing (ssh) connections but only prevented newly initiated ones. The attached patch allows to cut off existing connections as well, thus enforcing what the filter is showing.

	I had only tested with a configuration where the physical interface is connected to the bridge where the filters are applied. This patch now also solves a filtering problem where the physical interface is not connected to the bridge, but the bridge is given an IP address and the host routes between bridge and physical interface. Here the filters drop non-allowed traffic on the outgoing side on the host.

	nwfilter: resolve deadlock between VM ops and filter update
	 This is from a bug report and conversation on IRC where Soren reported that while a filter update is occurring on one or more VMs (due to a rule having been edited for example), a deadlock can occur when a VM referencing a filter is started.

	The problem is caused by the two locking sequences of

	qemu driver, qemu domain, filter             # for the VM start operation
	filter, qemu_driver, qemu_domain            # for the filter update operation

	that obviously don't lock in the same order. The problem is the 2nd lock sequence. Here the qemu_driver lock is being grabbed in qemu_driver:qemudVMFilterRebuild()

	The following solution is based on the idea of trying to re-arrange the 2nd sequence of locks as follows:

	qemu_driver, filter, qemu_driver, qemu_domain

	and making the qemu driver recursively lockable so that a second lock can occur, this would then lead to the following net-locking sequence

	qemu_driver, filter, qemu_domain

	where the 2nd qemu_driver lock has been ( logically ) eliminated.

	The 2nd part of the idea is that the sequence of locks (filter, qemu_domain) and (qemu_domain, filter) becomes interchangeable if all code paths where filter AND qemu_domain are locked have a preceding qemu_domain lock that basically blocks their concurrent execution

	So, the following code paths exist towards qemu_driver:qemudVMFilterRebuild where we now want to put a qemu_driver lock in front of the filter lock.

	-> nwfilterUndefine()   [ locks the filter ]
	    -> virNWFilterTestUnassignDef()
	        -> virNWFilterTriggerVMFilterRebuild()
	            -> qemudVMFilterRebuild()

	-> nwfilterDefine()
	    -> virNWFilterPoolAssignDef() [ locks the filter ]
	        -> virNWFilterTriggerVMFilterRebuild()
	            -> qemudVMFilterRebuild()

	-> nwfilterDriverReload()
	    -> virNWFilterPoolLoadAllConfigs()
	        ->virNWFilterPoolObjLoad()
	            -> virNWFilterPoolAssignDef() [ locks the filter ]
	                -> virNWFilterTriggerVMFilterRebuild()
	                    -> qemudVMFilterRebuild()

	-> nwfilterDriverStartup()
	    -> virNWFilterPoolLoadAllConfigs()
	        ->virNWFilterPoolObjLoad()
	            -> virNWFilterPoolAssignDef() [ locks the filter ]
	                -> virNWFilterTriggerVMFilterRebuild()
	                    -> qemudVMFilterRebuild()

	Qemu is not the only driver using the nwfilter driver, but also the UML driver calls into it. Therefore qemuVMFilterRebuild() can be exchanged with umlVMFilterRebuild() along with the driver lock of qemu_driver that can now be a uml_driver. Further, since UML and Qemu domains can be running on the same machine, the triggering of a rebuild of the filter can touch both types of drivers and their domains.

	In the patch below I am now extending each nwfilter callback driver with functions for locking and unlocking the (VM) driver (UML, QEMU) and introduce new functions for locking all registered callback drivers and unlocking them. Then I am distributing the lock-all-cbdrivers/unlock-all-cbdrivers call into the above call paths. The last shown callpath starting with nwfilterDriverStart() is problematic since it is initialize before the Qemu and UML drives are and thus a lock in the path would result in a NULL pointer attempted to be locked -- the call to virNWFilterTriggerVMFilterRebuild() is never called, so we never lock either the qemu_driver or the uml_driver in that path. Therefore, only the first 3 paths now receive calls to lock and unlock all callback drivers. Now that the locks are distributed where it matters I can remove the qemu_driver and uml_driver lock from qemudVMFilterRebuild() and umlVMFilterRebuild() and not requiring the recursive locks.

	For now I want to put this out as an RFC patch. I have tested it by 'stretching' the critical section after the define/undefine functions each lock the filter so I can (easily) concurrently execute another VM operation (suspend,start). That code is in this patch and if you want you can de-activate it. It seems to work ok and operations are being blocked while the update is being done.
	I still also want to verify the other assumption above that locking filter and qemu_domain always has a preceding qemu_driver lock.

	virsh: rework command parsing
	Old virsh command parsing mashes all the args back into a string and
	miss the quotes, this patches fix it. It is also needed for introducing
	qemu-monitor-command which is very useful.

	This patches uses the new vshCommandParser abstraction and adds
	vshCommandArgvParse() for arguments vector, so we don't need
	to mash arguments vector into a command sting.

	And the usage was changed:
	old:
	virsh [options] [commands]

	new:
	virsh [options]... [<command_string>]
	virsh [options]... <command> [args...]

	So we still support commands like:
	"define D.xml; dumpxml D" was parsed as a commands-string.

	and support commands like:
	we will not mash them into a string, we use new argv parser for it.

	But we don't support the command like:
	"define D.xml; dumpxml" was parsed as a command-name, but we have no such command-name.

	virsh: add vshCommandParser abstraction

2010-10-13  Lai Jiangshan  <laijs@cn.fujitsu.com>

	virsh: better handling the boolean option
	in old code the following commands are equivalent:
	     virsh # dumpxml --update-cpu=vm1
	     virsh # dumpxml --update-cpu vm1
	because the old code split the option argument into 2 parts:
	--update-cpu=vm1 is split into update-cpu and vm1,
	and update-cpu is a boolean option, so the parser takes vm1 as another
	argument, very strange.

	after this patch applied, the first one will become illegal.

	To achieve this, we don't parse/check options when parsing command sting,
	but check options when parsing a command argument. And the argument is
	not split when parsing command sting.

	virsh: better support double quote
	In origin code, double quote is only allowed at the begin or end
	"complicated argument"
	--some_opt="complicated string"  (we split this argument into 2 parts,

	This patch makes it allow double quote at any position of
	an argument:
	complicated" argument"
	complicated" "argument
	--"some opt=complicated string"

	This patch is also needed for the following patches,
	the following patches will not split option argument into 2 parts,
	so we have to allow double quote at any position of an argument.

	xen: Fix virDomain{At,De}tachDevice
	According to API documentation virDomain{At,De}tachDevice calls are
	supposed to only work on active guests for device hotplug. For anything
	beyond that, their *Flags variants have to be used.

	Despite the variant which was acked on libvirt mailing list
	(https://www.redhat.com/archives/libvir-list/2010-January/msg00385.html)
	commit ed9c14a7ef86d7a45a6d57cbfee5410fca428633 (by Jim Fehlig)
	introduced automagic behavior of these API calls for xen driver. Since
	January, these calls always change persistent configuration of a guest
	and if the guest is currently active, they also hot(un)plug the device.

	That change didn't follow API documentation and also broke device
	hot(un)plug for older xend implementations which do not support changing
	persistent configuration of a guest and hot(un)plugging in one step.

	This patch should not break anything for active guests. On the other
	hand, changing inactive guests is not supported any more.

	implement usb and pci hot attach in AppArmor driver
	Description: Implement AppArmorSetSecurityHostdevLabel() and
	AppArmorRestoreSecurityHostdevLabel() for hostdev and pcidev attach.

	virt-aa-helper also has to be adjusted because *FileIterate() is used for pci
	and usb devices and the corresponding XML for hot attached hostdev and pcidev
	is not in the XML passed to virt-aa-helper. The new '-F filename' option is
	added to append a rule to the profile as opposed to the existing '-f
	filename', which rewrites the libvirt-<uuid>.files file anew. This new '-F'
	option will append a rule to an existing libvirt-<uuid>.files if it exists,
	otherwise it acts the same as '-f'.

	load_profile() and reload_profile() have been adjusted to add an 'append'
	argument, which when true will use '-F' instead of '-f' when executing
	virt-aa-helper.

	All existing calls to load_profile() and reload_profile() have been adjusted
	to use the old behavior (ie append==false) except AppArmorSetSavedStateLabel()
	where it made sense to use the new behavior.

	This patch also adds tests for '-F'.

	tests: silence qemuargv2xmltest noise
	Before this patch, the testsuite was noisy:

	TEST: qemuargv2xmltest
	      ........................................ 40
	      ................20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument '-unknown', adding to the qemu namespace
	20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument 'parameter', adding to the qemu namespace
	.                        57  OK
	PASS: qemuargv2xmltest

	It's not a real failure (which is why the test was completing
	successfully), so much as an intentional warning to the user that use
	of the qemu namespace has the potential for undefined effects that
	leaked through the default logging behavior.  After this patch series,
	all tests can access any logged data, and this particular test can
	explicitly check for the presence or absence of the warning, such that
	the test output becomes:

	TEST: qemuargv2xmltest
	      ........................................ 40

	buf: Fix possible infinite loop in EscapeString, VSnprintf
	The current code will go into an infinite loop if the printf generated
	string is >= 1000, AND exactly 1 character smaller than the amount of free
	space in the buffer. When this happens, we are dropped into the loop body,
	but nothing will actually change, because count == (buf->size - buf->use - 1),
	and virBufferGrow returns unchanged if count < (buf->size - buf->use)

	Fix this by removing the '- 1' bit from 'size'. The *nprintf functions handle
	the NULL byte for us anyways, so we shouldn't need to manually accommodate
	for it.

	Here's a bug where we are actually hitting this issue:
	https://bugzilla.redhat.com/show_bug.cgi?id=602772

2010-09-03  Matthias Bolte  <matthias.bolte@googlemail.com>

	esx: Rework datastore path parsing and handling
	Instead of splitting the path part of a datastore path into
	directory and file name, keep this in one piece. An example:

	  "[datastore] directory/file"

	was split into this before:

	  datastoreName = "datastore"
	  directoryName = "directory"
	  fileName = "file"

	Now it's split into this:

	  datastoreName = "datastore"
	  directoryName = "directory"
	  directoryAndFileName = "directory/file"

	This simplifies code using esxUtil_ParseDatastorePath, because
	directoryAndFileName is used more often than fileName. Also the
	old approach expected the datastore path to reference an actual
	file, but this isn't always correct, especially when listing
	volumes. In that case esxUtil_ParseDatastorePath is used to parse
	a path that references a directory. This fails for a vpx://
	connection because the vCenter returns directory paths with a
	trailing '/'. The new approach is robust against this and the
	actual decision if the datastore path should reference a file or
	a directory is up to the caller of esxUtil_ParseDatastorePath.

	Update the tests accordingly.

	Explicitly pass uml_dir argument to user-mode-linux
	uml_dir overrides user-mode-linux's default of ~/.uml. This is needed
	for a couple of different reasons:

	libvirt expects this to default to virGetUserDirectory(geteuid()) +
	'/.uml'. However, user-mode-linux actually uses the HOME environment
	variable to determine where to look for the uml sockets, but if running
	libvirtd under sudo (which I routinely do during development), $HOME is
	pointing at my user's homedir, while my euid is 0, so libvirt looks in
	/root.

	Also (and this was my actual motivation for this patch), if HOME isn't
	set at all, user-mode-linux utterly fails. Looking at the code, it seems
	it's meant to emit a warning, but alas, it doesn't for some reason.
	If running libvirtd from upstart, HOME is not set, so any system using
	upstart will need this change.

	Allow chardev of type 'file' for UML domains.
	Like the comment suggested, we just open the file and pass the file
	descriptor to uml. The input "stream" is set to "null", since I couldn't
	find any useful way to actually use a file for input for a chardev and
	this also mimics what e.g. QEmu does internally.

	xen tests: Fix PV-VFB tests with RHEL-5 API
	RHEL-5 Xen doesn't support the old style vnc configuration. In sexpr, we

	xen tests: Fix missing "type ioemu" with rhel5-api
	The most common cause of errors with rhel5-api turn on was missing
	"(type ioemu)" in sexpr or its equivalent in XM configuration file. This
	happens because the presence of that part in sexpr (or cfg) depends on
	xen version the host is running. Let's avoid it by explicitly specifying
	interface model which ensures "type ioemu" will always be emitted.

	This patch adds

	    <model type='e1000'/>

	withing the interface element in all affected xml files. And

	    (model 'e1000')

	to all corresponding sexpr files with similar fix to cfg files. Such
	configuration works regardless on Xen version.

	nwfilter: extend nwfilter reload support
	In this patch I am extending and fixing the nwfilter module's reload support to stop all ongoing threads (for learning IP addresses of interfaces) and rebuild the filtering rules of all interfaces of all VMs when libvirt is started. Now libvirtd rebuilds the filters upon the SIGHUP signal and libvirtd restart.

	About the patch: The nwfilter functions require a virConnectPtr. Therefore I am opening a connection in qemudStartup, which later on needs to be closed outside where the driver lock is held since otherwise it ends up in a deadlock due to virConnectClose() trying to lock the driver as well.

	I have tested this now for a while with several machines running and needing the IP address learner thread(s). The rebuilding of the firewall rules seems to work fine following libvirtd restart or a SIGHUP. Also the termination of libvirtd worked fine.

	Make umlConnectTapDevice ask brAddTap for a persistent tap device.
	This patch does two things:

	 * It makes umlConnectTapDevice ask brAddTap for a persistent tap by
	   passing it a NULL tapfd argument.
	 * Stops umlConnectTapDevice from immediately dismantling the bridge
	   it just set up.

2010-08-15  Soren Hansen  <soren@linux2go.dk>

	Close fd's of persistent tap devices
	When passing a NULL tapfd argument to brAddTap, we need to close the fd
	of the tap device. If we don't, libvirt will keep the fd open
	indefinitely and renders the the guest unable to configure its side of
	the tap device.

	Make sure all command line arguments get passed to UML
	If umlBuildCommandLineChr fails (e.g. due to an unsupported chardev
	type), it returns NULL. umlBuildCommandLine does not check for this and
	sets this as an argument on the comand line, effectively ending the
	argument list. This patch checks for this case and sets the chardev to
	"none".

	nwfilter: Discard class D,E IP addresses when sniffing pkts
	When sniffing the network traffic, discard class D and E IP addresses when sniffing traffic. This was a reason why filters were not correctly rebuilt on VMs on the local 192.* network when libvirt was restarted and those VMs did not use a DHCP request to get its IP address.

	nwfilter: serialize execution of scripts with ebtables cmds
	While testing the SIGHUP handling and reloading of the nwfilter driver, I found that when the filters are rebuilt and mutlipe threads handled the individual interfaces, concurrently running multiple external bash scripts causes strange failures even though the executed ebtables commands are working on different tables for different interfaces. I cannot say for sure where the concurrency problems are caused, but introducing this lock definitely helps.

	--dhcp-no-override description from dnsmasq man page:

	      Disable  re-use  of  the  DHCP servername and filename fields as
	      extra option space. If it can, dnsmasq moves the boot server and
	      filename  information  (from  dhcp-boot)  out of their dedicated
	      fields into DHCP options. This make extra space available in the
	      DHCP  packet  for options but can, rarely, confuse old or broken
	      clients. This flag forces "simple and safe" behaviour  to  avoid
	      problems in such a case.

	It seems some virtual network card ROMs are this old/buggy so let's add
	--dhcp-no-override as a workaround for them. We don't use extra DHCP
	options so this should be safe. The option was added in dnsmasq-2.41,
	which becomes the minimum required version.

	qemu: Hack around asynchronous device_del
	device_del command is not synchronous for PCI devices, it merely asks
	the guest to release the device and returns. If the host wants to use
	that device before the guest actually releases it, we are in big
	trouble. To avoid this, we already added a loop which waits up to 10
	seconds until the device is actually released before we do anything else
	with that device. But we only added this loop for managed PCI devices
	before we try reattach them back to the host.

	However, we need to wait even for non-managed devices. We don't reattach
	them automatically, but we still want to prevent the host from using it.
	This was revealed thanks to sVirt: when we relabel sysfs files
	corresponding to the PCI device before the guest finished releasing the
	device, qemu is no longer allowed to access those files and if it wants
	(as a result of guest's request) to write anything to them, it just
	exits, which kills the guest.

	This is not a proper fix and needs some further work both on libvirt and
	qemu side in the future.

	length buffer, and therefore the potential to overflow.

	This change also provided the oppurtunity to eliminate the character

	past the end of the number, then simply skip the \n to get to the

	build: rerun bootstrap if po/Makevars got nuked
	There has been a frequent complaint of:

	make[2]: Entering directory `/home/remote/eblake/libvirt/po'
	make[2]: *** No rule to make target `/config.status', needed by `Makefile'.  Stop.

	It happens after nuking and regenerating the po directory,
	which is a common action after running anything like
	'make dist' or 'make rpm' that dirties all the .po files.

	Teach autogen.sh that it must regenerate po/Makevars to avoid
	the missing variable declaration, and teach cfg.mk to recognize
	that a nuked po directory is cause to rerun autogen.sh.

	* cfg.mk (_update_required): Check for po/Makevars.

	qemu: Fix PCI address allocation
	Patch version revamped by Eric Blake <eblake@redhat.com> of Jiri
	Denemark <jdenemar@redhat.com> original patch

	When attaching a PCI device which doesn't explicitly set its PCI
	address, libvirt allocates the address automatically. The problem is
	that when checking which PCI address is unused, we only check for those
	with slot number higher than the highest slot number ever used.

	Thus attaching/detaching such device several times in a row (31 is the
	theoretical limit, less then 30 tries are enough in practise) makes any
	further device attachment fail. Furthermore, attaching a device with
	predefined PCI address to 0:0:31 immediately forbids attachment of any
	PCI device without explicit address.

	This patch changes the logic so that we always check all PCI addresses
	before we say there is no PCI address available.

	Modifications from v1: revert back to remembering the last slot
	reserved, but allow wraparound to not be limited by the end.
	In this way, slots are still assigned in the same order as
	before the patch, rather than filling in the gaps closest to
	0 and risking making windows guests mad.

	* src/qemu/qemu_conf.c: fix pci reservation code to do a round-robbin
	  check of all available PCI splot availability before failing.

	Add iptables rule to fixup DHCP response checksum.
	This patch attempts to take advantage of a newly added netfilter
	module to correct for a problem with some guest DHCP client
	implementations when used in conjunction with a DHCP server run on the
	host systems with packet checksum offloading enabled.

	The problem is that, when the guest uses a RAW socket to read the DHCP
	response packets, the checksum hasn't yet been fixed by the IP stack,
	so it is incorrect.

	The fix implemented here is to add a rule to the POSTROUTING chain of
	the mangle table in iptables that fixes up the checksum for packets on
	the virtual network's bridge that are destined for the bootpc port (ie
	"dhcpc", ie port 68) port on the guest.

	Only very new versions of iptables will have this support (it will be
	in the next upstream release), so a failure to add this rule only
	results in a warning message. The iptables patch is here:

	  http://patchwork.ozlabs.org/patch/58525/

	A corresponding kernel module patch is also required (the backend of
	the iptables patch) and that will be in the next release of the
	kernel.

2010-08-02  Chris Lalancette  <clalance@redhat.com>

	Fix the ACS checking in the PCI code.
	When trying to assign a PCI device to a guest, we have
	to check that all bridges upstream of that device support
	ACS.  That means that we have to find the parent bridge of
	the current device, check for ACS, then find the parent bridge
	of that device, check for ACS, etc.  As it currently stands,
	the code to do this iterates through all PCI devices on the
	system, looking for a device that has a range of busses that
	included the current device's bus.

	That check is not restrictive enough, though.  Depending on
	how we iterated through the list of PCI devices, we could first
	find the *topmost* bridge in the system; since it necessarily had
	a range of busses including the current device's bus, we
	would only ever check the topmost bridge, and not check
	any of the intermediate bridges.

	Note that this also caused a fairly serious bug in the
	secondary bus reset code, where we could erroneously
	find and reset the topmost bus instead of the inner bus.

	This patch changes pciGetParentDevice() so that it first
	checks if a bridge device's secondary bus exactly matches
	the bus of the device we are looking for.  If it does, we've
	found the correct parent bridge and we are done.  If it does not,
	then we check to see if this bridge device's busses *include* the
	bus of the device we care about.  If so, we mark this bridge device
	as best, and go on.  If we later find another bridge device whose
	busses include this device, but is more restrictive, then we
	free up the previous best and mark the new one as best.  This
	algorithm ensures that in the normal case we find the direct
	parent, but in the case that the parent bridge secondary bus
	is not exactly the same as the device, we still find the
	correct bridge.

	This patch was tested by me on a 4-port NIC with a
	bridge without ACS (where assignment failed), a 4-port
	NIC with a bridge with ACS (where assignment succeeded),
	and a 2-port NIC with no bridges (where assignment
	succeeded).

	esx: Improve blocked task detection and fix race condition
	esxVI_WaitForTaskCompletion can take a UUID to lookup the
	corresponding domain and check if the current task for it
	is blocked by a question. It calls another function to do
	this: esxVI_LookupAndHandleVirtualMachineQuestion looks up
	the VirtualMachine and checks for a question. If there is
	a question it calls esxVI_HandleVirtualMachineQuestion to
	handle it.

	If there was no question or it has been answered the call
	to esxVI_LookupAndHandleVirtualMachineQuestion returns 0.
	If any error occurred during the lookup and answering
	process -1 is returned. The problem with this is, that -1
	is also returned when there was no error but the question
	could not be answered. So esxVI_WaitForTaskCompletion cannot
	distinguish between this two situations and reports that a
	question is blocking the task even when there was actually
	another problem.

	This inherent problem didn't surface until vSphere 4.1 when
	you try to define a new domain. The driver tries to lookup
	the domain that is just in the process of being registered.
	There seems to be some kind of race condition and the driver
	manages to issue a lookup command before the ESX server was
	able to register the domain. This used to work before.

	Due to the return value problem described above the driver
	reported a false error message in that case.

	To solve this esxVI_WaitForTaskCompletion now takes an
	additional occurrence parameter that describes whether or
	not to expect the domain to be existent. Also add a new
	parameter to esxVI_LookupAndHandleVirtualMachineQuestion
	that allows to distinguish if the call returned -1 because
	of an actual error or because the question could not be
	answered.

	libcurl allows to disable the type-checking code that triggers those

	Invert logic for checking for QEMU disk cache options
	QEMU has had two different syntax for disk cache options

	 Old: on|off
	 New: writeback|writethrough|none

	QEMU recently added another 'unsafe' option which broke the
	libvirt check. We can avoid this & future breakage, if we
	do a negative check for the old syntax, instead of a positive
	check for the new syntax

	qemu: Allow setting boot menu on/off
	Add a new element to the <os> block:

	  <bootmenu enable="yes|no"/>

	Which maps to -boot,menu=on|off on the QEMU command line.

	I decided to use an explicit 'enable' attribute rather than just make the
	bootmenu element boolean. This allows us to treat lack of a bootmenu element
	as 'use hypervisor default'.

	libvirt-guests: Don't throw errors if libvirtd is not installed
	When only client parts of libvirt are installed (i.e., no libvirtd
	daemon), libvirt-guests init script in its default configuration would
	throw seriously looking errors during host shutdown:

	Running guests on default URI: error: unable to connect to
	'/var/run/libvirt/libvirt-sock', libvirtd may need to be started: No
	such file or directory
	error: failed to connect to the hypervisor

	This patch changes the script to print rather harmless message in that
	situation:

	Running guests on default URI: libvirtd not installed; skipping this
	URI.

	Force FLR on for buggy SR-IOV devices.
	Some buggy PCI devices actually support FLR, but
	forget to advertise that fact in their PCI config space.
	However, Virtual Functions on SR-IOV devices are

	on if this is a virtual function.

	pciResetDevice: use inactive devices to determine safe reset
	When doing a PCI secondary bus reset, we must be sure that there are no
	active devices on the same bus segment.  The active device tracking is
	designed to only track host devices that are active in use by guests.
	This ignores host devices that are actively in use by the host.  So the
	current logic will reset host devices.

	Switch this logic around and allow sbus reset when we are assigning all
	devices behind a bridge to the same guest at guest startup or as a result
	of a single attach-device command.

	* src/util/pci.h: change signature of pciResetDevice to add an
	  inactive devices list
	* src/qemu/qemu_driver.c src/xen/xen_driver.c: use (or not) the new
	  functionality of pciResetDevice() depending on the place of use
	* src/util/pci.c: implement the interface and logic changes

	qemudDomainAttachHostPciDevice refactor to use new helpers
	- src/qemu/qemu_driver.c: Eliminate code duplication by using the new
	  helpers qemuPrepareHostdevPCIDevices and qemuDomainReAttachHostdevDevices.
	  This reduces the number of open coded calls to pciResetDevice.

	Add helpers qemuPrepareHostdevPCIDevice and qemuDomainReAttachHostdevDevices
	- src/qemu/qemu_driver.c: These new helpers take hostdev list and count
	  directly rather than getting them indirectly from domain definition.

	Commit 68719c4bddb85fbcc931a5b7d99ac7c8a0af09b0 added the disk format
	probing option. This makes virt-aa-helper-test fail because the domain

	virt-aa-helper: Fix return value of add_file_path
	Commit a8853344994a7c6aaca882a5e949ab5536821ab5 added this
	function and wrapped vah_add_file in it. vah_add_file may
	return -1, 0, 1. It returns 1 in case the call to valid_path
	detects a restricted file. The original code treated a return
	value != 0 as error. The refactored code treats a return
	value < 0 as error. This triggers segfault in virt-aa-helper
	and breaks virt-aa-helper-test for the restricted file tests.

	Make sure that add_file_path returns -1 on error.

2010-07-24  Chris Lalancette  <clalance@redhat.com>

	Add tests for the new Qemu namespace XML.
	Thanks to DV for knocking together the Relax-NG changes
	quickly for me.

	Changes since v1:
	 - Change the domain.rng to correspond to the new schema
	 - Don't allocate caps->ns in testQemuCapsInit since it is a static table

	Changes since v2:
	 - Change domain.rng to add restrictions on allowed environment names

	Changes since v3:
	 - Remove a bogus comment in the tests

	Qemu remote protocol.
	Since we are adding a new "per-hypervisor" protocol, we
	make it so that the qemu remote protocol uses a new
	PROTOCOL and PROGRAM number.  This allows us to easily
	distinguish it from the normal REMOTE protocol.

	This necessitates changing the proc in remote_message_header
	from a "remote_procedure" to an "unsigned", which should
	be the same size (and thus preserve the on-wire protocol).

	Changes since v1:
	 - Fixed up a couple of script problems in remote_generate_stubs.pl
	 - Switch an int flag to a bool in dispatch.c

	Changes since v2:
	 - None

	Changes since v3:
	 - Change unsigned proc to signed proc, to conform to spec

2010-07-24  Chris Lalancette  <clalance@redhat.com>

	Qemu arbitrary monitor commands.
	Implement the qemu driver's virDomainQemuMonitorCommand
	and hook it into the API entry point.

	Changes since v1:
	 - Rename the (external) qemuMonitorCommand to qemuDomainMonitorCommand
	 - Add virCheckFlags to qemuDomainMonitorCommand

	Changes since v2:
	 - Drop ATTRIBUTE_UNUSED from the flags

	Changes since v3:
	 - Add a flag to priv so we only print out monitor command warning once.  Note
	   that this has not been plumbed into qemuDomainObjPrivateXMLFormat or
	   qemuDomainObjPrivateXMLParse, which means that if you run a monitor command,
	   restart libvirtd, and then run another monitor command, you may get an
	   an erroneous VIR_INFO.  It's a pretty minor matter, and I didn't think it
	   warranted the additional code.
	 - Add BeginJob/EndJob calls around EnterMonitor/ExitMonitor

2010-07-24  Chris Lalancette  <clalance@redhat.com>

	Qemu Monitor API entry point.
	Add the library entry point for the new virDomainQemuMonitorCommand()
	entry point.  Because this is not part of the "normal" libvirt API,
	it gets its own header file, library file, and will eventually
	get its own over-the-wire protocol later in the series.

	Changes since v1:
	 - Go back to using the virDriver table for qemuDomainMonitorCommand, due to
	   linking issues
	 - Added versioning information to the libvirt-qemu.so

	Changes since v2:
	 - None

	Changes since v3:
	 - Add LGPL header to libvirt-qemu.c
	 - Make virLibConnError and virLibDomainError macros instead of function calls

	Changes since v4:
	 - Move exported symbols to libvirt_qemu.syms

2010-07-24  Chris Lalancette  <clalance@redhat.com>

	Handle arbitrary qemu command-lines in qemuParseCommandLine.
	Now that we have the ability to specify arbitrary qemu
	command-line parameters in the XML, use it to handle unknown
	command-line parameters when doing a native-to-xml conversion.

	Changes since v1:
	 - Rename num_extra to num_args
	 - Fix up a memory leak on an error path

	Changes since v2:
	 - Add a VIR_WARN when adding the argument via qemu:arg

	Changes since v3:
	 - None

2010-07-24  Chris Lalancette  <clalance@redhat.com>

	Qemu arbitrary command-line arguments.
	Implement the qemu hooks for XML namespace data.  This
	allows us to specify a qemu XML namespace, and then
	specify:

	<qemu:commandline>
	 <qemu:arg value='arg'/>
	 <qemu:env name='name' value='value'/>
	</qemu:commandline>

	In the domain XML.

	Changes since v1:
	 - Change the <qemu:arg>arg</qemu:arg> XML to <qemu:arg value='arg'/> XML
	 - Fix up some memory leaks in qemuDomainDefNamespaceParse
	 - Rename num_extra and extra to num_args and args, respectively
	 - Fixed up some error messages
	 - Make sure to escape user-provided data in qemuDomainDefNamespaceFormatXML

	Changes since v2:
	 - Add checking to ensure environment variable names are valid
	 - Invert the logic in qemuDomainDefNamespaceFormatXML to return early

	Changes since v3:
	 - Change strspn() to c_isalpha() check of first letter of environment variable

2010-07-24  Chris Lalancette  <clalance@redhat.com>

	Add namespace callback hooks to domain_conf.
	This patch adds namespace XML parsers to be hooked into
	the main domain parser.  This allows for individual hypervisor
	drivers to add per-namespace XML into the main domain XML.

	Changes since v1:
	 - Use a statically declared table for caps->ns, removing the need to
	   allocate/free it.

	Changes since v2:
	 - None

	Changes since v3:
	 - None

	Fix SEGV on exit after domainEventDeregister()
	When the last callback is removed using domainEventDeregister(), the
	events dispatcher is deregistered from the C-library, but
	domainEventsCallbacks is still an empty list.
	On shutdown __del__() deregisters the dispatacher again, which SEGVs

		# You need the event-loop implementation from the Python examples;
		# give the file a name which is importable by Python.
		ln examples/domain-events/events-python/event-test.py eloop.py
		python -c 'from eloop import *

		virEventLoopPureStart()
		c = libvirt.open("xen:///")
		c.domainEventRegister(dump, None)
		c.domainEventDeregister(dump)
		sys.exit(0)'

	domainEventDeregister() needs to delete domainEventCallbacks so subsequent
	calls to __del__() and domainEventRegister() choose the right code paths.
	Setting it to None is not enough, since calling domainEventRegiser() again
	would trigger an TypeError.

	pciSharesBusWithActive fails to find multiple devices on bus
	The first conditional is always true which means the iterator will
	never find another device on the same bus.

	    if (dev->domain != check->domain ||
	        dev->bus != check->bus ||
	  ----> (check->slot == check->slot &&
	         check->function == check->function)) <-----

	The goal of that check is to verify that the device is either:

	  in a different pci domain
	  on a different bus
	  is the same identical device

	This means libvirt may issue a secondary bus reset when there are
	devices
	on that bus that actively in use by the host or another guest.

	Set a stable & high MAC addr for guest TAP devices on host
	A Linux software bridge will assume the MAC address of the enslaved
	interface with the numerically lowest MAC addr. When the bridge
	changes MAC address there is a period of network blackout, so a
	change should be avoided. The kernel gives TAP devices a completely
	random MAC address. Occassionally the random TAP device MAC is lower
	than that of the physical interface (eth0, eth1etc) that is enslaved,
	causing the bridge to change its MAC.

	This change sets an explicit MAC address for all TAP devices created
	using the configured MAC from the XML, but with the high byte set
	to 0xFE. This should ensure TAP device MACs are higher than any
	physical interface MAC.

	* src/qemu/qemu_conf.c, src/uml/uml_conf.c: Pass in a MAC addr

	Remove erroneous setting of return value to errno.
	One error exit in virStorageBackendCreateBlockFrom was setting the
	return value to errno. The convention for volume build functions is to
	return 0 on success or -1 on failure. Not only was it not necessary to
	set the return value (it defaults to -1, and is set to 0 when
	everything has been successfully completed), in the case that some
	caller were checking for < 0 rather than != 0, they would incorrectly
	believe that it completed successfully.

	Change virDirCreate to return -errno on failure.
	virDirCreate also previously returned 0 on success and errno on
	failure. This makes it fit the recommended convention of returning 0
	on success, -errno (ie a negative number) on failure.

	Make virStorageBackendCopyToFD return -errno.
	Previously virStorageBackendCopyToFD would simply return -1 on
	error. This made the error return from one of its callers inconsistent
	(createRawFileOpHook is supposed to return -errno, but if
	virStorageBackendCopyToFD failed, createRawFileOpHook would just
	return -1). Since there is a useful errno in every case of error
	return from virStorageBackendCopyToFD, and since the other uses of
	that function ignore the return code (beyond simply checking to see if
	it is < 0), this is a safe change.

2010-07-22  Laine Stump  <laine@laine.org>

	Change virFileOperation to return -errno (ie < 0) on error.
	virFileOperation previously returned 0 on success, or the value of
	errno on failure. Although there are other functions in libvirt that
	use this convention, the preferred (and more common) convention is to
	return 0 on success and -errno (or simply -1 in some cases) on
	failure. This way the check for failure is always (ret < 0).

	* src/util/util.c - change virFileOperation and virFileOperationNoFork to
	                    return -errno on failure.

	* src/storage/storage_backend.c, src/qemu/qemu_driver.c

	Rearrange VGA/IDE controller address reservation
	The first VGA and IDE devices need to have fixed PCI address
	reservations. Currently this is handled inline with the other
	non-primary VGA/IDE devices. The fixed virtio balloon device
	at slot 3, ensures auto-assignment skips the slots 1/2. The
	virtio address will shortly become configurable though. This
	means the reservation of fixed slots needs to be done upfront
	to ensure that they don't get re-used for other devices.

	This is more or less reverting the previous changeset:

	  Fix restore of QEMU guests with PCI device reservation

	The difference is that this time, instead of unconditionally

	Fix a deadlock in bi-directional p2p concurrent migration.
	If you try to execute two concurrent migrations p2p
	from A->B and B->A, the two libvirtd's will deadlock
	trying to perform the migrations.  The reason for this is
	that in p2p migration, the libvirtd's are responsible for
	making the RPC Prepare, Migrate, and Finish calls.  However,
	they are currently holding the driver lock while doing so,
	which basically guarantees deadlock in this scenario.

	This patch fixes the situation by adding
	qemuDomainObjEnterRemoteWithDriver and
	qemuDomainObjExitRemoteWithDriver helper methods.  The Enter
	take an additional object reference, then drops both the
	domain object lock and the driver lock.  The Exit takes
	both the driver and domain object lock, then drops the
	reference.  Adding calls to these Enter and Exit helpers
	around remote calls in the various migration methods
	seems to fix the problem for me in testing.

	This should make the situation safe. The additional domain
	object reference ensures that the domain object won't disappear
	while this operation is happening.  The BeginJob that is called
	inside of qemudDomainMigratePerform ensures that we can't execute a
	second migrate (or shutdown, or save, etc) job while the
	migration is active.  Finally, the additional check on the state
	of the vm after we reacquire the locks ensures that we can't
	be surprised by an external event (domain crash, etc).

	Make virsh setmaxmem balloon only when successful.
	After playing around with virsh setmaxmem for a bit,
	I ran into some surprising behavior; if a hypervisor does
	not support the virDomainSetMaxMemory() API, but the value
	specified for setmaxmem is less than the current amount
	of memory in the domain, the domain would be ballooned
	down *before* an error was reported.

	To make this more consistent, run virDomainSetMaxMemory()
	before trying to shrink; that way, if an error is thrown,
	no changes to the running domain are made.

	Use unsigned long in cmdSetmem.
	The virsh command "setmem" takes as input a number that

	cmdSetmem to properly parse this as an unsigned long instead
	of an int.

	fsync new storage volumes even if new volume was copied.
	Originally the storage volume files were opened with O_DSYNC to make
	sure they were flushed to disk immediately. It turned out that this
	was extremely slow in some cases, so the O_DSYNC was removed in favor
	of just calling fsync() after all the data had been written. However,
	this call to fsync was inside the block that is executed to zero-fill
	the end of the volume file. In cases where the new volume is copied
	from an old volume, and they are the same length, this fsync would
	never take place.

	Now the fsync is *always* done, unless there is an error (in which
	case it isn't important, and is most likely inappropriate.

2010-07-20  Laine Stump  <laine@laine.org>

	Don't skip zero'ing end of volume file when inputvol is shorter than newvol
	A missing set of braces around an error condition caused us to skip
	zero'ing out the remainder of a new volume file if the new volume was
	longer than the original (the goto was supposed to be taken only in
	the case of error, but was always being taken).

2010-07-20  Chris Lalancette  <clalance@redhat.com>

	Always clear out the last_error in virshReportError.
	Otherwise you can get bogus "unknown error" printouts on
	subsequent commands.

	Fix up inconsistent virsh option error reporting.
	The virsh option error reporting was not being used
	consistently; some commands would spit out errors on
	missing required options while others would just silently fail.
	However, vshCommandOptString knows which ones are required
	and which ones aren't, so make it spit out an error where
	appropriate.  The rest of the patch is just cleaning up
	the uses of vshCommandOptString to deal with the new error
	reporting.

	Use the extract backing store format in storage volume lookup
	The storage volume lookup code was probing for the backing store
	format, instead of using the format extracted from the file
	itself. This meant it could report in accurate information. If
	a format is included in the file, then use that in preference,
	with probing as a fallback.

	Rewrite qemu-img backing store format handling
	When creating qcow2 files with a backing store, it is important
	to set an explicit format to prevent QEMU probing. The storage
	backend was only doing this if it found a 'kvm-img' binary. This
	is wrong because plenty of kvm-img binaries don't support an
	explicit format, and plenty of 'qemu-img' binaries do support
	a format. The result was that most qcow2 files were not getting
	a backing store format.

	This patch runs 'qemu-img -h' to check for the two support
	argument formats

	  '-o backing_format=raw'
	  '-F raw'

	and use whichever option it finds

	Refactor virStorageFileGetMetadataFromFD to separate functionality
	The virStorageFileGetMetadataFromFD did two jobs in one. First

	Extract the backing store format as well as name, if available
	When QEMU opens a backing store for a QCow2 file, it will
	normally auto-probe for the format of the backing store,
	rather than assuming it has the same format as the referencing
	file. There is a QCow2 extension that allows an explicit format
	for the backing store to be embedded in the referencing file.
	This closes the auto-probing security hole in QEMU.

	This backing store format can be useful for libvirt users
	of virStorageFileGetMetadata, so extract this data and report
	it.

	QEMU does not require disk image backing store files to be in
	the same format the file linkee. It will auto-probe the disk
	format for the backing store when opening it. If the backing
	store was intended to be a raw file this could be a security
	hole, because a guest may have written data into its disk that
	then makes the backing store look like a qcow2 file. If it can
	trick QEMU into thinking the raw file is a qcow2 file, it can
	access arbitrary files on the host by adding further backing
	store links.

	To address this, callers of virStorageFileGetMeta need to be
	told of the backing store format. If no format is declared,
	they can make a decision whether to allow format probing or
	not.

	CVE-2010-2242 Apply a source port mapping to virtual network masquerading
	IPtables will seek to preserve the source port unchanged when
	doing masquerading, if possible. NFS has a pseudo-security
	option where it checks for the source port <= 1023 before
	allowing a mount request. If an admin has used this to make the

	man pages: update authors and copyright notice for libvirtd and virsh
	This patch removes the individual author names from the libvirtd and virsh

	RFC: Canonicalize block device paths
	There are many naming conventions for partitions associated with a
	block device.  Some of the major ones are:

	/dev/foo -> /dev/foo1
	/dev/foo1 -> /dev/foo1p1
	/dev/mapper/foo -> /dev/mapper/foop1
	/dev/disk/by-path/foo -> /dev/disk/by-path/foo-part1

	The universe of possible conventions isn't clear.  Rather than trying
	to understand all possible conventions, this patch divides devices
	into two groups, device mapper devices and everything else.  Device
	mapper devices seem always to follow the convention of device ->
	devicep1; everything else is canonicalized.

	daemon: dispatch.c should include stdio.h (and stdarg.h)
	dispatch.c requires stdio.h (and stdarg.h), however, currently
	dispatch.c implicitly relys on rpc/xdr.h to include stdio.h.
	If rpc/xdr.h unxpectedly does not include stdio.h, the compilation
	of dispatch.c fails.

	This can happen, for example, when portablexdr is installed
	under /usr/local; because portablexdr's rpc/xdr.h does not
	include stdio.h and gcc looks up it not /usr/include/rpc/xdr.h.

	Note that stdarg.h is also included according to man va_start,

	cpu: Fail when CPU type cannot be detected from XML
	When autodetecting whether XML describes guest or host CPU, the presence
	of <arch> element is checked. If it's present, we treat the XML as host
	CPU definition. Which is right, since guest CPU definitions do not
	contain <arch> element. However, if at the same time the root <cpu>
	element contains `match' attribute, we would silently ignore it and
	still treat the XML as host CPU. We should rather refuse such invalid
	XML.

	cpuCompare: Fix comparison of two host CPUs
	When a CPU to be compared with host CPU describes a host CPU instead of
	a guest CPU, the result is incorrect. This is because instead of
	treating additional features in host CPU description as required, they

	In the current libvirt PCI code, there is no checking whether

	phyp: don't steal storage management from other drivers
	Fix regression introduced in commit a4a287242 - basically, the
	phyp storage driver should only accept the same URIs that the
	main phyp driver is willing to accept.  Blindly accepting all
	URIs meant that the phyp storage driver was being consulted for
	'virsh -c qemu:///session pool-list --all', rather than the
	qemu storage driver, then since the URI was not for phyp, attempts
	to then use the phyp driver crashed because it was not initialized.

	lxc: Fix virsh console doesn't work after restarting libvirtd
	Because tty path is unexpectedly not saved in the live configuration
	file of a domain, libvirtd cannot get the console of the domain back
	after restarting.

	The reason why the tty path isn't saved is that, to save the tty path,
	the save function, virDomainSaveConfig, requires that the target domain
	is running (pid != -1), however, lxc driver calls the function before
	starting the domain to pass the configuration to controller.

	To ensure to save the tty path, the patch lets lxc driver call the save
	function again after starting the domain.

	lxc: Fix error handlings in lxcContainerRenameAndEnableInterfaces
	The function is expected to return negative value on failure,

	Selectively ignore domainSetSecurityAllLabel failure in domain restore
	When the saved domain image is on an NFS share, at least some part of

	ignore the errors.

	call until it gets to a partial path that *can* be stat'ed.

	Fix migration in text mode and shared storage migration in json mode
	The patches for shared storage migration were not correctly written
	for json mode. Thus the 'blk' and 'inc' parameters were never being
	set. In addition they didn't set the QEMU_MONITOR_MIGRATE_BACKGROUND
	so migration was synchronous. Due to multiple bugs in QEMU's JSON

	Avoid blocking all APIs during incoming migration
	During incoming migration the QEMU monitor is not able to be
	used. The incoming migration code did not keep hold of the
	job lock because migration is split across multiple API calls.
	This meant that further monitor commands on the guest would
	hang until migration finished with no timeout.

	In this change the qemuDomainMigratePrepare method sets the
	job flag just before it returns. The qemuDomainMigrateFinish
	method checks for this job flag & clears it once done. This
	prevents any use of the monitor between prepare+finish steps.

	The qemuDomainGetJobInfo method is also updated to refresh
	the job elapsed time. This means that virsh domjobinfo can
	return time data during incoming migration

	Set labelling for character devices in security drivers
	When configuring serial, parallel, console or channel devices
	with a file, dev or pipe backend type, it is necessary to label

	file, it is neccessary to pre-create (touch) the file if it does

	cgroup: Enable memory.use_hierarchy of cgroup for domain
	Through conversation with Kumar L Srikanth-B22348, I found
	that the function of getting memory usage (e.g., virsh dominfo)
	doesn't work for lxc with ns subsystem of cgroup enabled.

	This is because of features of ns and memory subsystems.
	Ns creates child cgroup on every process fork and as a result
	processes in a container are not assigned in a cgroup for
	domain (e.g., libvirt/lxc/test1/). For example, libvirt_lxc
	and init (or somewhat specified in XML) are assigned into
	libvirt/lxc/test1/8839/ and libvirt/lxc/test1/8839/8849/,
	respectively. On the other hand, memory subsystem accounts
	memory usage within a group of processes by default, i.e.,
	it does not take any child (and descendant) groups into
	account. With the two features, virsh dominfo which just
	checks memory usage of a cgroup for domain always returns
	zero because the cgroup has no process.

	Setting memory.use_hierarchy of a group allows to account
	(and limit) memory usage of every descendant groups of the group.
	By setting it of a cgroup for domain, we can get proper memory
	usage of lxc with ns subsystem enabled. (To be exact, the
	setting is required only when memory and ns subsystems are
	enabled at the same time, e.g., mount -t cgroup none /cgroup.)

2010-06-24  Ryota Ozaki  <ozaki.ryota@gmail.com>

	cgroup: Change virCgroupRemove to remove all descendant groups at first
	As same as normal directories, a cgroup cannot be removed if it
	contains sub groups. This patch changes virCgroupRemove to remove
	all descendant groups (subdirectories) of a target group before
	removing the target group.

	The handling is required when we run lxc with ns subsystem of cgroup.
	Ns subsystem automatically creates child cgroups on every process
	forks, but unfortunately the groups are not removed on process exits,
	so we have to remove them by ourselves.

	With this patch, such child (and descendant) groups are surely removed
	at lxc shutdown, i.e., lxcVmCleanup which calls virCgroupRemove.

	Add '-nodefconfig' command line arg to QEMU
	We already use the '-nodefaults' command line arg with QEMU to stop
	it adding any default devices to guests. Unfortunately, QEMU will
	load global config files from /etc/qemu that may also add default
	devices. These aren't blocked by '-nodefaults', so we need to also
	add the '-nodefconfig' arg to prevent that.

	Unfortunately these global config files are also used to define
	custom CPU models. So in blocking global hardware device addition
	we also block definitions of new CPU models. Libvirt doesn't know
	about these custom CPU models though, so it would never make use
	of them anyway. Thus blocking them via -nodefconfig isn't a show
	stopping problem. We would need to expand libvirt's own CPU model
	XML database to support these instead.

	Fix reference handling leak on qemuMonitor
	The current code pattern requires that callers of qemuMonitorClose
	check for the return value == 0, and if so, set priv->mon = NULL
	and release the reference held on the associated virDomainObjPtr

	The change d84bb6d6a3bd2fdd530184cc9743249ebddbee71 violated that
	requirement, meaning that priv->mon never gets set to NULL, and
	a reference count is leaked on virDomainObjPtr.

	This design was a bad one, so remove the need to check the return
	valueof qemuMonitorClose(). Instead allow registration of a
	callback that's invoked just when the last reference on qemuMonitorPtr
	is released.

	Finally there was a potential reference leak in qemuConnectMonitor
	in the failure path.

	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add a destroy
	  callback invoked from qemuMonitorFree

	Make checks for inactive QEMU guest more robust
	Before issuing monitor commands it is neccessary to check whether
	the guest is still running. Most places use virDomainIsActive()
	correctly, but a few relied on 'priv->mon != NULL'. In theory
	these should be equivalent, but the release of the last reference
	count on priv->mon can be delayed a small amount of time until
	the event handler is finally deregistered. A further ref counting
	bug also means that priv->mon might be never released. In such a
	case, code could mistakenly issue a monitor command and wait for
	a response that will never arrive, effectively leaving the QEMU
	driver waiting on virCondWait() forever..

	To protect against these possibilities, make sure all code uses
	virDomainIsActive(), not 'priv->mon != NULL'

	* src/qemu/qemu_driver.c: Replace 'priv->mon != NULL' with

	nwfilter: add XML attribute to control iptables state match
	This patch adds an optional XML attribute to a nwfilter rule to give the user control over whether the rule is supposed to be using the iptables state match or not. A rule may now look like shown in the XML below with the statematch attribute either having value '0' or 'false' (case-insensitive).

	[...]
	<rule action='accept' direction='in' statematch='false'>
	<tcp srcmacaddr='1:2:3:4:5:6'
	           srcipaddr='10.1.2.3' srcipmask='32'
	           dscp='33'
	           srcportstart='20' srcportend='21'
	           dstportstart='100' dstportend='1111'/>
	</rule>
	[...]

	I am also extending the nwfilter schema and add this attribute to a test case.

	This patch works around a recent extension of the netlink driver I had made use of when building the netlink messages. Unfortunately older kernels don't accept IFLA_IFNAME + name of interface as a replacement for the interface's index, so this patch now gets the interface index ifindex if it's not provided (ifindex <= 0).

2010-06-17  Matthias Bolte  <matthias.bolte@googlemail.com>

	Add several missing vir*Free calls in libvirtd's remote code
	Justin Clift reported a problem with adding virStoragePoolIsPersistent
	to virsh's pool-info command, resulting in a strange problem. Here's
	an example:

	    virsh # pool-create-as images_dir3 dir - - - - "/home/images2"
	    Pool images_dir3 created

	    virsh # pool-info images_dir3
	    Name:           images_dir3
	    UUID:           90301885-94eb-4ca7-14c2-f30b25a29a36
	    State:          running
	    Capacity:       395.20 GB
	    Allocation:     30.88 GB
	    Available:      364.33 GB

	    virsh # pool-destroy images_dir3
	    Pool images_dir3 destroyed

	At this point the images_dir3 pool should be gone (because it was
	transient) and we should be able to create a new pool with the same name:

	    virsh # pool-create-as images_dir3 dir - - - - "/home/images2"
	    Pool images_dir3 created

	    virsh # pool-info images_dir3
	    Name:           images_dir3
	    UUID:           90301885-94eb-4ca7-14c2-f30b25a29a36
	    error: Storage pool not found

	The new pool got the same UUID as the first one, but we didn't specify
	one. libvirt should have picked a random UUID, but it didn't.

	It turned out that virStoragePoolIsPersistent leaks a reference to the
	storage pool object (actually remoteDispatchStoragePoolIsPersistent does).
	As a result, pool-destroy doesn't remove the virStoragePool for the
	"images_dir3" pool from the virConnectPtr's storagePools hash on libvirtd's
	side. Then the second pool-create-as get's the stale virStoragePool object
	associated with the "images_dir3" name. But this object has the old UUID.

	This commit ensures that all get_nonnull_* and make_nonnull_* calls for
	libvirt objects are matched properly with vir*Free calls. This fixes the
	reference leaks and the reported problem.

	All remoteDispatch*IsActive and remoteDispatch*IsPersistent functions were
	affected. But also remoteDispatchDomainMigrateFinish2 was affected in the
	success path. I wonder why that didn't surface earlier. Probably because
	domainMigrateFinish2 is executed on the destination host and in the common
	case this connection is opened especially for the migration and gets closed
	after the migration is done. So there was no chance to run into a problem
	because of the leaked reference.

	Fix auto-adding of virtio serial controllers
	The domain parsing code would auto-add a virtio serial controller
	if it saw any virtio serial channel defined. Unfortunately it
	always added a controller with index=0, even if the channel address
	specified an index != 0. It only added one controller, even if
	multiple controllers were referenced by channels. Finally, it let
	the ports+vectors parameters initialize to zero instead of -1, which
	prevented the controllers accepting any ports.

	  virtio serial controllers. Add all neccessary virtio serial
	  controllers, instead of hardcoding controller 0

	Fix dereference of potentially freed pointer in qemudDomainSaveFlags
	The pointer to the xml describing the domain is saved into an object

	phyp: Strict check when listing domains

2010-06-03  Stefan Berger  <stefanb@us.ibm.com>

	add 802.1Qbh and 802.1Qbg handling
	This patch that adds support for configuring 802.1Qbg and 802.1Qbh
	switches. The 802.1Qbh part has been successfully tested with real
	hardware. The 802.1Qbg part has only been tested with a (dummy)
	server that 'behaves' similarly to how we expect lldpad to 'behave'.

	The following changes were made during the development of this patch:

	 - Merging Scott's v13-pre1 patch
	 - Fixing endptr related bug while using virStrToLong_ui() pointed out
	   by Jim Meyering
	 - Addressing Jim Meyering's comments to v11
	 - requiring mac address to the vpDisassociateProfileId() function to
	   pass it further to the 802.1Qbg disassociate part (802.1Qbh untouched)
	 - determining pid of lldpad daemon by reading it from /var/run/libvirt.pid
	   (hardcode as is hardcode alson in lldpad sources)
	 - merging netlink send code for kernel target and user space target
	   (lldpad) using one function nlComm() to send the messages
	 - adding a select() after the sending and before the reading of the
	   netlink response in case lldpad doesn't respond and so we don't hang
	 - when reading the port status, in case of 802.1Qbg, no status may be
	   received while things are 'in progress' and only at the end a status
	   will be there.
	 - when reading the port status, use the given instanceId and vf to pick
	   the right IFLA_VF_PORT among those nested under IFLA_VF_PORTS.
	 - never sending nor parsing IFLA_PORT_SELF type of messages in the
	   802.1Qbg case
	 - iterating over the elements in a IFLA_VF_PORTS to pick the right
	   IFLA_VF_PORT by either IFLA_PORT_PROFILE and given profileId
	   (802.1Qbh) or IFLA_PORT_INSTANCE_UUID and given instanceId (802.1Qbg)
	   and reading the current status in IFLA_PORT_RESPONSE.
	 - recycling a previous patch that adds functionality to interface.c to
	   - get the vlan identifier on an interface
	   - get the flags of an interface and some convenience function to
	     check whether an interface is 'up' or not (not currently used here)
	 - adding function to determine the root physical interface of an
	   interface. For example if a macvtap is linked to eth0.100, it will
	   find eth0. Also adding a function that finds the vlan on the 'way to
	   the root physical interface'
	 - conveying the root physical interface name and index in case of 802.1Qbg
	 - conveying mac address of macvlan device and vlan identifier in
	   IFLA_VFINFO_LIST[ IFLA_VF_INFO[ IFLA_VF_MAC(mac), IFLA_VF_VLAN(vlan) ] ]
	   to (future) lldpad via netlink
	  - To enable build with --without-macvtap rename the
	    [dis|]associatePortProfileId functions, prepend 'vp' before their
	    name and make them non-static functions.
	  - Renaming variable multicast to nltarget_kernel and inverting
	    the logic
	  - Addressing Jim Meyering's comments; this also touches existing
	    code for example for correcting indentation of break statements or
	    simplification of switch statements.
	  - Renamed occurrencvirVirtualPortProfileDef to virVirtualPortProfileParamses
	  - 802.1Qbg part prepared for sending a RTM_SETLINK and getting
	    processing status back plus a subsequent RTM_GETLINK to
	    get IFLA_PORT_RESPONSE.
	    Note: This interface for 802.1Qbg may still change
	  - [David Allan] move getPhysfn inside IFLA_VF_PORT_MAX to avoid
	compiler
	    warning when latest if_link.h isn't available
	  - move from Stefan's 802.1Qb{g|h} XML v8 to v9
	  - move hostuuid and vf index calcs to inside doPortProfileOp8021Qbh
	  - remove debug fprintfs
	  - use virGetHostUUID (thanks Stefan!)
	  - fix compile issue when latest if_link.h isn't available
	  - change poll timeout to 10s, at 1/8 intervals
	     - if polling times out, log msg and return -ETIMEDOUT
	  - Add Stefan's code for getPortProfileStatus
	  - Poll for up to 2 secs for port-profile status, at 1/8 sec intervals:
	     - if status indicates error, abort openMacvtapTap
	     - if status indicates success, exit polling
	     - if status is "in-progress" after 2 secs of polling, exit
	       polling loop silently, without error

	My patch finishes out the 802.1Qbh parts, which Stefan had mostly complete.
	I've tested using the recent kernel updates for VF_PORT netlink msgs and
	enic for Cisco's 10G Ethernet NIC.  I tested many VMs, each with several
	direct interfaces, each configured with a port-profile per the XML.  VM-to-VM,
	and VM-to-external work as expected.  VM-to-VM on same host (using same NIC)
	works same as VM-to-VM where VMs are on diff hosts.  I'm able to change
	settings on the port-profile while the VM is running to change the virtual
	port behaviour.  For example, adjusting a QoS setting like rate limit.  All
	VMs with interfaces using that port-profile immediatly see the effect of the
	change to the port-profile.

	I don't have a SR-IOV device to test so source dev is a non-SR-IOV device,
	but most of the code paths include support for specifing the source dev and
	VF index.  We'll need to complete this by discovering the PF given the VF
	linkdev.  Once we have the PF, we'll also have the VF index.  All this info-
	mation is available from sysfs.

2010-06-02  Justin Clift  <justin@salasaga.org>

	Add --source-format argument to virsh pool-define-as and pool-create-as
	When creating pools from dedicated disks, the existing pool-define-as
	and pool-create-as commands are a bit non-optimal.

	Ideally, a person would be able to specify all of the required options
	directly on the command line instead of having to edit the XML.

	At the moment, there is no way to specify the format type (ie gpt) so it
	gets included in the XML the pool is constructed with.

	Please find attached a simple (tested) patch to add an optional
	"--source-format 'type'" to virsh.  This is patched against current git
	master and will apply cleanly.

	Also created a Red Hat BZ ticket for this (#597790) for tracking.

	storage: Check for invalid storage mode before opening
	If a directory pool contains pipes or sockets, a pool start can fail or hang:

	https://bugzilla.redhat.com/show_bug.cgi?id=589577

	We already try to avoid these special files, but only attempt after
	opening the path, which is where the problems lie. Unify volume opening
	into helper functions, which use the proper open() flags to avoid error,
	followed by fstat to validate storage mode.

	Previously, virStorageBackendUpdateVolTargetInfoFD attempted to enforce the
	storage mode check, but allowed callers to detect this case and silently
	continue. In practice, only the FS backend was using this feature, the rest
	were treating unknown mode as an error condition. Unfortunately the InfoFD
	function wasn't raising an error message here, so error reporting was
	busted.

	This patch adds 2 functions: virStorageBackendVolOpen, and
	virStorageBackendVolOpenModeSkip. The latter retains the original opt out
	semantics, the former now throws an explicit error.

	This patch maintains the previous volume mode checks: allowing specific
	modes for specific pool types requires a bit of surgery, since VolOpen
	is called through several different helper functions.

	v2: Use ATTRIBUTE_NONNULL. Drop stat check, just open with
	    O_NONBLOCK|O_NOCTTY.

	v3: Move mode check logic back to VolOpen. Use 2 VolOpen functions with
	    different error semantics.

	v4: Make second VolOpen function more extensible. Didn't opt to change
	    FS backend defaults, this can just be to fix the original bug.

	v5: Prefix default flags with VIR_, use ATTRIBUTE_RETURN_CHECK

	macvtap: cannot support target device name
	Since the macvtap device needs active tear-down and the teardown logic
	is based on the interface name, it can happen that if for example 1 out
	of 3 interfaces was successfully created, that during the failure path
	the macvtap's target device name is used to tear down an interface that
	is doesn't own (owned by another VM).

	So, in this patch, the target interface name is reset so that there is
	no target interface name and the interface name is always cleared after
	a tear down.

	Fix failing virGetHostname.
	We've been running into a lot of situations where
	virGetHostname() is returning "localhost", where a plain
	gethostname() would have returned the correct thing.  This
	is because virGetHostname() is *always* trying to canonicalize
	the name returned from gethostname(), even when it doesn't
	have to.

	This patch changes virGetHostname so that if the value returned
	from gethostname() is already FQDN or localhost, it returns
	that string directly.  If the value returned from gethostname()
	is a shortened hostname, then we try to canonicalize it.  If
	that succeeds, we returned the canonicalized hostname.  If
	that fails, and/or returns "localhost", then we just return
	the original string we got from gethostname() and hope for
	the best.

	Note that after this patch it is up to clients to check whether
	"localhost" is an allowed return value.  The only place
	where it's currently not is in qemu migration.

	vepa: parsing for 802.1Qb{g|h} XML
	This patch parses the following two XML descriptions, one for
	802.1Qbg and one for 802.1Qbh, and stores the data internally.
	The actual triggering of the switch setup protocol has not been
	implemented here but the relevant code to do that should go into
	the functions associatePortProfileId() and disassociatePortProfileId().

	   <interface type='direct'>
	      <source dev='eth0.100' mode='vepa'/>
	      <model type='virtio'/>
	      <virtualport type='802.1Qbg'>
	        <parameters managerid='12' typeid='0x123456' typeidversion='1'
	         instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/>
	      </virtualport>
	      <filterref filter='clean-traffic'/>
	    </interface>

	    <interface type='direct'>
	      <source dev='eth0.100' mode='vepa'/>
	      <model type='virtio'/>
	      <virtualport type='802.1Qbh'>
	        <parameters profileid='my_profile'/>
	      </virtualport>
	    </interface>

	I'd suggest to use this patch as a base for triggering the setup
	protocol with the 802.1Qb{g|h} switch.

	Several rounds of changes were made to this patch. The
	following is a list of these changes.
	- Renamed structure virVirtualPortProfileDef to virVirtualPortProfileParams
	  as per Daniel Berrange's request
	- Addressing Daniel Berrange's comments:
	 - removing macvtap.h's dependency on domain_conf.h by
	   moving the virVirtualPortProfileDef structure into macvtap.h
	   and not passing virtDomainNetDefPtr to any functions in
	   macvtap.c
	- Addressed most of Chris Wright's comments:
	  - indicating error in case virtualport XML node cannot be parsed
	    properly
	  - parsing hex and decimal numbers using virStrToLong_ui() with
	    parameter '0' for base
	  - tgifname (target interface name) variable wasn't necessary
	    to pass to openMacvtapTap function anymore
	- assigning the virtual port data structure to the virDomainNetDef
	  only if it was previously parsed
	- make sure that the error code returned by openMacvtapTap() is a negative n
	  in case the associatePortProfileId() function failed.
	- renaming vsi in the XML to virtualport
	- replace all occurrences of vsi in the source as well
	- removing mode and MAC address parameters from the functions that
	  will communicate with the hareware diretctly or indirectly
	- moving the associate and disassociate functions to the end of the
	  file for subsequent patches to easier make them generally available
	  for export
	- passing the macvtap interface name rather than the link device since
	  this otherwise gives funny side effects when using netlink messages
	  where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev
	  all of a sudden gets the MAC address of the macvtap interface.
	- Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case
	  we wanted to use hook scripts for the setup and so the setup doesn't fail
	  here.
	- if instance ID UUID is not supplied it will automatically be generated
	  - adapted schema to make instance ID UUID optional
	  - added test case
	- parser and XML generator have been separated into their own
	  functions so they can be re-used elsewhere (passthrough case
	  for example)
	- Adapted XML parser and generator support the above shown type
	  (802.1Qbg, 802.1Qbh).
	- Adapted schema to above XML
	- Adapted test XML to above XML
	- Passing through the VM's UUID which seems to be necessary for
	  802.1Qbh -- sorry no host UUID
	- adding virtual function ID to association function, in case it's
	  necessary to use (for SR-IOV)

	storage: Sanitize pool target paths
	Spurious / in a pool target path makes life difficult for apps using the

	Fix handling of disk backing stores with cgroups
	The cgroups ACL code was only allowing the primary disk image.
	It is possible to chain images together, so we need to search
	for backing stores and add them to the ACL too. Since the ACL
	only handles block devices, we ignore the EINVAL we get from
	plain files. In addition it was missing code to teardown the
	cgroup when hot-unplugging a disk

	Fix up basic migration.
	Basic live migration was broken by the commit that added
	non-shared block support in two ways:

	1)  It added a virCheckFlags() to doNativeMigrate().  Besides
	the fact that typical usage of virCheckFlags() is in driver
	entry points, and doNativeMigrate() is not an entry point,
	it was missing important flags like VIR_MIGRATE_LIVE.  Move
	the virCheckFlags to the top-level qemuDomainMigratePrepare2
	and friends.

	2)  It also added a memory leak in qemuMonitorTextMigrate()
	by not freeing the memory used by virBufferContentAndReset().
	This is fixed by storing the pointer in a temporary variable
	and freeing it at the end.

	With this patch in place, normal live migration works again.

	v3: Instead of the churn for virCheckFlagsUI and UL, instead
	always promote flags to an unsigned long and always use %lx
	for the fprintf.
	v2: Add back flags check, which required adding virCheckFlagsUI
	and virCheckFlagsUL

	qemu: Allow using regular audio backends with VNC
	Currently all host audio backends are disabled if a VM is using VNC, in
	favor of the QEMU VNC audio extension. Unfortunately no released VNC

	to work if using VNC.

	Add a new config option in qemu.conf which allows changing libvirt's
	behavior, but keep the default intact.

	Query block allocation extent from QEMU monitor
	The virDomainGetBlockInfo API allows query physical block
	extent and allocated block extent. These are normally the
	same value unless storing a special format like qcow2
	inside a block device. In this scenario we can query QEMU
	to get the actual allocated extent.

	Fix race in finding available vnc port
	The qemu driver contains a subtle race in the logic to find next
	available vnc port.  Currently it iterates through all available ports
	and returns the first for which bind(2) succeeds.  However it is possible
	that a previously issued port has not yet been bound by qemu, resulting
	in the same port used for a subsequent domain.

	This patch addresses the race by using a simple bitmap to "reserve" the
	ports allocated by libvirt.

	V2:
	  - Put port bitmap in struct qemud_driver
	  - Initialize bitmap in qemudStartup

	V3:
	  - Check for failure of virBitmapGetBit

	Domain snapshot RNG and tests.

2010-05-21  Chris Lalancette  <clalance@redhat.com>

	Fix up the python bindings for snapshotting.
	This involved a few fixes.  To start with,
	an virDomainSnapshot object is really tied to a
	domain, not a connection, so we have to generate
	a slightly different object so that we can get
	at self._dom for the object.

	Next, we had to "dummy" up an override piece of
	XML with a bogus argument that the function doesn't
	actually take.  That's so that the generator places
	virDomainRevertToSnapshot underneath the correct
	class (namely, the virDomain class).

	Finally, we had to hand-implement the
	virDomainRevertToSnapshot implementation, ignoring the
	bogus pointer we are being passed.

	With all of this in place, I was able to successfully
	take a snapshot and revert to it using only the
	Python bindings.

	Protect against NULL pointer flaws in monitor usage
	History has shown that there are frequent bugs in the QEMU driver
	code leading to the monitor being invoked with a NULL pointer.
	Although the QEMU driver code should always report an error in
	this case before invoking the monitor, as a safety net put in a
	generic check in the monitor code entry points.

	* src/qemu/qemu_monitor.c: Safety net to check for NULL monitor
	  object

2010-05-18  Daniel P. Berrange  <berrange@redhat.com>

	Fix multiple potential NULL pointer references in monitor usage
	Any method which intends to invoke a monitor command must have
	a check for virDomainObjIsActive() before using the monitor to
	ensure that priv->mon != NULL.

	There is one subtle edge case in this though. If a method invokes
	multiple monitor commands, and calls qemuDomainObjExitMonitor()
	in between two of these commands then there is no guarentee that
	priv->mon != NULL anymore. This is because the QEMU process may
	exit or die at any time, and because qemuDomainObjEnterMonitor()
	releases the lock on virDomainObj, it is possible for the background
	thread to close the monitor handle and thus qemuDomainObjExitMonitor
	will release the last reference allowing priv->mon to become NULL.

	This affects several methods, most notably migration but also some
	hotplug methods. This patch takes a variety of approaches to solve
	the problem, depending on the particular usage scenario. Generally
	though it suffices to add an extra virDomainObjIsActive() check
	if qemuDomainObjExitMonitor() was called during the method.

	Setting dynamic_ownership=0 in /etc/libvirt/qemu.conf prevents
	libvirt's DAC security driver from setting uid/gid on disk
	files when starting/stopping QEMU, allowing the admin to manage
	this manually. As a side effect it also stopped setting of
	uid/gid when saving guests to a file, which completely breaks
	save when QEMU is running non-root. Thus saved state labelling
	code must ignore the dynamic_ownership parameter

	* src/qemu/qemu_security_dac.c: Ignore dynamic_ownership=0 when
	  doing save/restore image labelling

	Don't reset user/group/security label on shared filesystems during migrate
	When QEMU runs with its disk on NFS, and as a non-root user, the
	disk is chownd to that non-root user. When migration completes
	the last step is shutting down the QEMU on the source host. THis
	normally resets user/group/security label. This is bad when the
	VM was just migrated because the file is still in use on the dest
	host. It is thus neccessary to skip the reset step for any files
	found to be on a shared filesystem

	* src/libvirt_private.syms: Export virStorageFileIsSharedFS
	* src/util/storage_file.c, src/util/storage_file.h: Add a new
	  method virStorageFileIsSharedFS() to determine if a file is
	  on a shared filesystem (NFS, GFS, OCFS2, etc)
	* src/qemu/qemu_driver.c: Tell security driver not to reset
	  disk labels on migration completion
	* src/qemu/qemu_security_dac.c, src/qemu/qemu_security_stacked.c,
	  src/security/security_selinux.c, src/security/security_driver.h,
	  src/security/security_apparmor.c: Add ability to skip disk
	  restore step for files on shared filesystems.

	Fix handling of disk backing stores with cgroups
	The cgroups ACL code was only allowing the primary disk image.
	It is possible to chain images together, so we need to search
	for backing stores and add them to the ACL too. Since the ACL
	only handles block devices, we ignore the EINVAL we get from
	plain files. In addition it was missing code to teardown the
	cgroup when hot-unplugging a disk

	* src/qemu/qemu_driver.c: Allow backing stores in cgroup ACLs
	  and add missing teardown code in unplug path

	Fix possible crash in handling IO Error event
	If the IO error event does not include a reason, then there
	is a possible crash dispatching the event

	* src/conf/domain_event.c: Missing check for a NULL reason before
	  strduping allows for a crash

2010-05-14  Daniel P. Berrange  <berrange@redhat.com>

	Add support for NIC hotplug using netdev_add in QEMU
	QEMU is gaining a new monitor command netdev_add for hotplugging
	NICs using the netdev backend code. We already support this on
	the command this, though it is disabled. This adds support for
	hotplug too, also to remain disabled until 0.13 QEMU is released

	* src/qemu/qemu_driver.c: Support netdev hotplug for NICs
	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
	  src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h,
	  src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add

2010-05-12  Jiri Denemark  <jdenemar@redhat.com>

	Fix monitor ref counting when adding event handle
	When closing a monitor using qemuMonitorClose(), we are aware of
	the possibility the monitor is still being used somewhere:

	    /* NB: ordinarily one might immediately set mon->watch to -1
	     * and mon->fd to -1, but there may be a callback active
	     * that is still relying on these fields being valid. So
	     * we merely close them, but not clear their values and
	     * use this explicit 'closed' flag to track this state */

	but since we call virEventAddHandle() on that monitor without increasing
	its ref counter, the monitor is still freed which makes possible users
	of it quite unhappy. The unhappiness can lead to a hang if qemuMonitorIO
	tries to lock mutex which no longer exists.

2010-05-12  Jiri Denemark  <jdenemar@redhat.com>

	Remove watches before calling REMOTE_PROC_CLOSE
	First calling REMOTE_PROC_CLOSE and then removing watches might lead to
	a hang as HANGUP event can be triggered before the watches are actually
	removed but after virConnectPtr is already freed. As a result of that
	remoteDomainEventFired() would try to lock uninitialized mutex, which
	would hang for ever.

	qemu: live migration with non-shared storage for kvm
	Support for live migration between hosts that do not share storage was
	added to qemu-kvm release 0.12.1.
	It supports two flags:
	-b migration without shared storage with full disk copy
	-i migration without shared storage with incremental copy (same base image
	shared between source and destination).

	I tested the live migration without shared storage (both flags) for native
	and p2p with and without tunnelling.  I also verified that the fix doesn't
	affect normal migration with shared storage.

	configure.ac: Avoid uname, which breaks cross-compilation
	When cross-compiling on Linux, configure will misdetect the target as

	nwfilter: skip some interfaces on filter update
	When a filter is updated, only those interfaces must have their old
	rules cleared that either reference the filter directly or indirectly
	through another filter. Remember between the different steps of the
	instantiation of the filters which interfaces must be skipped. I am
	using a hash map to remember the names of the interfaces and store a
	bogus pointer to ~0 into it that need not be freed.

	pass info where request stems from to have rules applied
	For the decision on whether to instantiate the rules, the check for a
	pending IP address learn request is not sufficient since then only the
	thread could instantiate the rules. So, a boolean needs to be passed
	when the thread instantiates the filter rules late and the IP address
	learn request is still pending in order to override the check for the
	pending learn request. If the rules are to be updated while the thread
	is active, this will not be done immediately but the thread will do that
	later on.

	The reason of the failure is that lxc driver unexpectedly re-uses

	again. The failure will happen when a domain has multiple network
	interfaces and the names of those are not specified in XML.

	Add support for another explicit IO error event
	This introduces a new event type

	   VIR_DOMAIN_EVENT_ID_IO_ERROR_REASON

	This event is the same as the previous VIR_DOMAIN_ID_IO_ERROR
	event, but also includes a string describing the cause of
	the event.

	Thus there is a new callback definition for this event type

	typedef void (*virConnectDomainEventIOErrorReasonCallback)(virConnectPtr conn,
	                                                           virDomainPtr dom,

	Prevent updates while IP address learn thread is running
	Prevent updating and tearing down of filter while the IP

	rules applied.

	Syncronize the teardown of rules with the thread
	Introduce a function to notify the IP address learning

	Fix a virsh edit memory leak
	When running virsh edit, we are unlinking and setting
	the tmp variable to NULL before going to the end of the

	Fix a qemuDomainPCIAddressSetFree memory leak
	qemuDomainPCIAddressSetFree was freeing up the hash

	is mis-using LDADD; it shouldn't be putting direct paths to

	Fix handling of security driver restore failures in QEMU domain save
	In cases where the security driver failed to restore a label after a

	This is not good, because the operation has in fact completed and
	cannot be rolled back completely. Label restore is non-critical, so
	just log the problem instead. Also add a missing restore call in
	the error cleanup path

2010-04-28  Daniel P. Berrange  <berrange@redhat.com>

	Fix QEMU domain save to block devices with cgroups enabled
	When cgroups is enabled, access to block devices is likely to be
	restricted to a whitelist. Prior to saving a guest to a block device,
	it is necessary to add the block device to the whitelist. This is
	not required upon restore, since QEMU reads from stdin

	* src/qemu/qemu_driver.c: Add block device to cgroups whitelist
	  if neccessary during domain save.

2010-04-28  Daniel P. Berrange  <berrange@redhat.com>

	Fix QEMU save/restore with block devices
	The save process was relying on use of the shell >> append
	operator to ensure the save data was placed after the libvirt
	header + XML. This doesn't work for block devices though.
	Replace this code with use of 'dd' and its 'seek' parameter.
	This means that we need to pad the header + XML out to a
	multiple of dd block size (in this case we choose 512).

	The qemuMonitorMigateToCommand() monitor API is used for both
	save/coredump, and migration via UNIX socket. We can't simply
	switch this to use 'dd' since this causes problems with the
	migration usage. Thus, create a dedicated qemuMonitorMigateToFile
	which can accept an filename + offset, and remove the filename
	from the current qemuMonitorMigateToCommand() API

	nwfilter: let qemu's after-migration packet pass
	Qemu currently sends an Ethernet packet with protocol id 0x835 once a VM
	was successfully migrated. The content of the packet looks like a
	gratuitous RARP, just with the wrong protocol ID, which should be
	0x8035. I wrote some filters to let either one of the packets pass and
	am adapting the clean-traffic sample filter to use it. I am also
	doing some changes on the existing ARP filter which was lacking a
	test for source MAC address.

	nwfilter: add support for RAPR protocol
	This patch adds support for the RARP protocol. This may be needed due to
	qemu sending out a RARP packet (at least that's what it seems to want to
	do even though the protocol id is wrong) when migration finishes and
	we'd need a rule to let the packets pass.

	Unfortunately my installation of ebtables does not understand -p RARP
	and also seems to otherwise depend on strings in /etc/ethertype
	translated to protocol identifiers. Therefore I need to pass -p 0x8035
	for RARP. To generally get rid of the dependency of that file I switch
	all so far supported protocols to use their protocol identifier in the
	-p parameter rather than the string.

	I am also extending the schema and added a test case.

	changes from v1 to v2:
	- added test case into patch

2010-04-27  Jiri Denemark  <jdenemar@redhat.com>

	Ignore qemu STOP event when stopping CPUs
	With JSON qemu monitor, we get a STOP event from qemu whenever qemu
	stops guests CPUs. The downside of it is that vm->state is changed to
	PAUSED and a new generic paused event is send to applications. However,
	when we ask qemu to stop the CPUs we are not really interested in qemu
	event and we usually want to issue a more specific event.

	By setting vm->status to PAUSED before actually sending the request to
	qemu (and resetting it back if the request fails) we can ignore the
	event since the event handler does nothing when the guest is already
	paused. This solution is quite hacky but unfortunately it's the best
	solution which I was able to come up with and it doesn't introduce a
	race condition.

	Changes from V1 to V2:  - using INT_BUFSIZE_BOUND() to determine the length of the buffersize for printing and integer into
	 - not explicitly initializing static var threadsTerminate to false
	anymore, since that's done automatically

	Changes after V2:
	  - removed while looks in case of OOM error
	  - removed on ifaceDown() call
	  - preceding one ifaceDown() call with an ifaceCheck() call

	Since the name of an interface can be the same between stops and starts
	of different VMs I have to switch the IP address learning thread to use
	the index of the interface to determine whether an interface is still
	available or not - in the case of macvtap the thread needs to listen for
	traffic on the physical interface, thus having to time out periodically
	to check whether the VM's macvtap device is still there as an indication
	that the VM is still alive. Previously the following sequence of 2 VMs
	with macvtap device

	virsh start testvm1; virsh destroy testvm1 ; virsh start testvm2

	would not terminate the thread upon testvm1's destroy since the name of
	the interface on the host could be the same (i.e, macvtap0) on testvm1
	and testvm2, thus it was easily race-able. The thread would then
	determine the IP address parameter for testvm2 but apply the rule set
	for testvm1. :-(
	I am also introducing a lock for the interface (by name) that the thread
	must hold while it listens for the traffic and releases when it
	terminates upon VM termination or 0.5 second thereafter. Thus, the new
	thread for a newly started VM with the same interface name will not
	start while the old one still holds the lock. The only other code that I
	see that also needs to grab the lock to serialize operation is the one
	that tears down the firewall that were established on behalf of an
	interface.

	I am moving the code applying the 'basic' firewall rules during the IP
	address learning phase inside the thread but won't start the thread
	unless it is ensured that the firewall driver has the ability to apply
	the 'basic' firewall rules.

	Fix locking in qemudDomainCoreDump
	The hang fix in d376b7d63ec1ef24ba4c812d58b9a414ddb561f8 was incomplete
	since it left quite a few {Enter,Exit}Monitor calls which require driver
	to be unlocked. Since the driver is locked throughout the whole
	function, {Enter,Exit}MonitorWithDriver need to be used instead to
	ensure driver is not locked when issuing monitor commands.

	Poll for migration end every 50ms instead of 50us

	Fake host CPU for qemu tests

	Use configured CPU model if possible
	Adds ability to provide a preferred CPU model for CPUID data decoding.
	Such model would be considered as the best possible model (if it's
	supported by hypervisor) regardless on number of features which have to
	be added or removed for describing required CPU.

2010-04-22  Jiri Denemark  <jdenemar@redhat.com>

	Support removing features when converting data to CPU
	So far, when CPUID data were converted into CPU model and features, the
	features can only be added to the model. As a result, when a guest asked
	for something like "qemu64,-svm" it would get a qemu32 plus a bunch of
	additional features instead.

	This patch adds support for removing feature from the base model.
	Selection algorithm remains the same: the best CPU model is the model
	which requires lowest number of features to be added/removed from it.

2010-04-22  Jiri Denemark  <jdenemar@redhat.com>

	Move MIN macro to util.h so that others can use it

	Deal with CPU models in []
	Qemu committed a patch which list some CPU names in [] when asked for
	supported CPUs (qemu -cpu ?). Yet, it needs such CPUs to be passed
	without those square braces. When probing for supported CPU models, we
	can just strip the square braces and pretend we have never seen them.

	Fix initial VCPU pinning in qemu driver
	First, inital VCPU pinning is set correctly but then it is reset by
	assigning qemu process to a new cgroup (which contains all CPUs). It's
	easily fixed by swapping these two actions.

	esx: Don't treat an empty root snapshot list as error
	An empty root snapshot list was considered as error condition. Creating a

	Use virCheckFlags for APIs added in 0.8.0

2010-04-16  Jiri Denemark  <jdenemar@redhat.com>

	Introduce virCheckFlags for consistent flags checking
	The idea is that every API implementation in driver which has flags
	parameter should first call virCheckFlags() macro to check the function
	was called with supported flags:

	    virCheckFlags(VIR_SUPPORTED_FLAG_1 |
	                  VIR_SUPPORTED_FLAG_2 |
	                  VIR_ANOTHER_SUPPORTED_FLAG, -1);

	The error massage which is printed when unsupported flags are passed
	looks like:

	    invalid argument in virFooBar: unsupported flags (0x2)

	Where the unsupported flags part only prints those flags which were
	passed but are not supported rather than all flags passed.

	qemudDomainAttachSCSIDisk: avoid FP NULL-ptr-deref from clang
	* src/util/conf.c (virConfParseValue): Add an sa_assert.

	xend_internal.c: assure clang that we do not dereference NULL
	* src/xen/xend_internal.c (xend_parse_sexp_desc_char): Add three

	sa_assert: assert-like macro, enabled only for use with static analyzers
	Among some here, there is a strong aversion to the use of "assert", yet
	some others think it is essential (when applied judiciously) even --
	perhaps "especially" -- at the heart of libraries and core hypervisor-
	related code.
	Here is a compromise that lets us make assertions about the code (e.g.,
	to tell static analyzers about invariants) without even a hint of risk
	of an abort.
	* src/internal.h [STATIC_ANALYSIS]: Include <assert.h>.
	(sa_assert): Define.  A no-op most of the time, but equivalent
	to classical assert when STATIC_ANALYSIS is nonzero.

	necessary CLI tools and a shutdown function to free allocated memory.
	The rest of the patch mostly deals with availability of the CLI tools
	and to not call certain code blocks if a tool is not available and that

	nwfilter: fix for directionality of ICMP traffic
	Changes from V1 to V2 of this patch
	- I had reversed the logic thinking that icmp type 0 is a echo

	- Found that ebtables takes the --ip-tos argument only as a hex number

	This patch enables the skipping of some of the ICMP traffic rules on the
	iptables level under certain circumstances so that the following filter
	properly enables unidirectional pings:

	<filter name='testcase'>
	    <uuid>d6b1a2af-def6-2898-9f8d-4a74e3c39558</uuid>
	    <!-- allow incoming ICMP Echo Request -->

	    <!-- allow outgoing ICMP Echo Reply -->
	    <rule action='accept' direction='out' priority='500'>

	nwfilter: Support for learning a VM's IP address
	This patch implements support for learning a VM's IP address. It uses
	the pcap library to listen on the VM's backend network interface (tap)
	or the physical ethernet device (macvtap) and tries to capture packets
	with source or destination MAC address of the VM and learn from DHCP
	Offers, ARP traffic, or first-sent IPv4 packet what the IP address of
	the VM's interface is. This then allows to instantiate the network
	traffic filtering rules without the user having to provide the IP
	parameter somewhere in the filter description or in the interface
	description as a parameter. This only supports to detect the parameter
	IP, which is for the assumed single IPv4 address of a VM. There is not
	support for interfaces that may have multiple  IP addresses (IP
	aliasing) or IPv6 that may then require more than one valid IP address
	to be detected. A VM can have multiple independent interfaces that each
	uses a different IP address and in that case it will be attempted to
	detect each one of the address independently.

	So, when for example an interface description in the domain XML has
	looked like this up to now:

	    <interface type='bridge'>
	      <source bridge='mybridge'/>
	      <model type='virtio'/>
	      <filterref filter='clean-traffic'>
	        <parameter name='IP' value='10.2.3.4'/>
	      </filterref>
	    </interface>

	you may omit the IP parameter:

	    <interface type='bridge'>
	      <source bridge='mybridge'/>
	      <model type='virtio'/>
	      <filterref filter='clean-traffic'/>
	    </interface>

	Internally I am walking the 'tree' of a VM's referenced network filters
	and determine with the given variables which variables are missing. Now,
	the above IP parameter may be missing and this causes a libvirt-internal
	thread to be started that uses the pcap library's API to listen to the
	backend interface  (in case of macvtap to the physical interface) in an
	attempt to determine the missing IP parameter. If the backend interface
	disappears the thread terminates assuming the VM was brought down. In
	case of a macvtap device a timeout is being used to wait for packets
	from the given VM (filtering by VM's interface MAC address). If the VM's
	macvtap device disappeared the thread also terminates. In all other
	cases it tries to determine the IP address of the VM and will then apply
	the rules late on the given interface, which would have happened
	immediately if the IP parameter had been explicitly given. In case an
	error happens while the firewall rules are applied, the VM's backend
	interface is 'down'ed preventing it to communicate. Reasons for failure
	for applying the network firewall rules may that an ebtables/iptables
	command failes or OOM errors. Essentially the same failure reasons may
	occur as when the firewall rules are applied immediately on VM start,
	except that due to the late application of the filtering rules the VM
	now is already running and cannot be hindered anymore from starting.
	Bringing down the whole VM would probably be considered too drastic.
	While a VM's IP address is attempted to be determined only limited
	updates to network filters are allowed. In particular it is prevented
	that filters are modified in such a way that they would introduce new
	variables.

	A caveat: The algorithm does not know which one is the appropriate IP
	address of a VM. If the VM spoofs an IP address in its first ARP traffic
	or IPv4 packets its filtering rules will be instantiated for this IP
	address, thus 'locking' it to the found IP address. So, it's still
	'safer' to explicitly provide the IP address of a VM's interface in the
	filter description if it is known beforehand.

	nwfiler: fix due to non-symmetric src mac address match in iptables
	The attached patch fixes a problem due to the mac match in iptables only
	supporting --mac-source and no --mac-destination, thus it not being
	symmetric. Therefore a rule like this one

	<rule action='drop' direction='out'>
	  <all match='no' srcmacaddr='$MAC'/>
	</rule>

	should only have the MAC match on traffic leaving the VM and not test
	for the same source MAC address on traffic that the VM receives.

2010-04-06  Chris Lalancette  <clalance@redhat.com>

	Better error reporting in virsh.
	When hitting failures in virsh, a common idiom is
	to jump to a cleanup label, free some resources, and
	then return a FALSE error code to vshCommandRun.
	In theory, vshCommandRun is then supposed to print
	out the last error.  The problem is that many of
	the cleanup paths have library calls to free resources,
	and all of those library calls clear out the last error.
	This is leading to situations where no error is being
	reported at all.

	This patch remedies the situation somewhat by
	printing out the errors inside the command methods
	themselves when we know it will go through a cleanup
	path that will lose the error.

	discarded once the domain is created.

	from the API would load the state from the managed file, similary if
	the domain is autostarted when libvirtd starts.
	Once a domain has restarted his managed save image is destroyed,

	./autogen.sh

	Use git diff to expose whether the submodule has untracked changes,
	which are typical on an incremental pull if .gnulib was updated but
	the user did not manually run 'git submodule update'.

	After this patch is applied, I encountered a new problem when
	following the reproducing pattern.  Basically, the change to .gnulib
	between libvirt's commit 96e5a2d4 and this patch introduced a change
	to sys_ioctl.in.h, but gnulib (intentionally) does not make the
	replacement headers depend on Makefile changes.  Therefore, I ended up
	with the generated replacement header being broken:
	gnulib/lib/sys/ioctl.h complained about a use of @.  But that seems
	like something that should be fixed upstream in gnulib's bootstrap
	script (that is, when doing a gnulib update, all files created from
	.in.h file should probably be deleted).  Without the benefit of that
	proposed gnulib fix, I worked around the problem by manually removing
	the stale gnulib/lib/sys/ioctl.h.

	- ebtables complains about protocol identifiers lower than 0x600, so already discard anything lower than 0x600 in the parser

	- make the protocol entry types more readable using a #define for its entries

	- continue parsing a filtering rule even if a faulty entry is encountered; return an error value at the end and let the caller decide what to do with the rule's object

	1) 'wallclock' is changed to 'track', and the possible values are 'boot'
	 (corresponds to old 'host'), 'guest', and 'wall'.

	2) 'mode' has an additional value 'smpsafe'

	3) when tickpolicy='catchup', there can be an optional sub-element of
	   timer called 'catchup':

	   <catchup threshold=123 slew=120 limit=10000/>

	Those three values are all longs, always optional, and if they are present,

	Allow domain disk images on root-squash NFS to coexist with security driver.
	(suggested by Daniel Berrange, tested by Dan Kenigsberg)

	virStorageFileGetMetadata will fail for disk images that are stored on
	a root-squash NFS share that isn't world-readable.
	SELinuxSetSecurityImageLabel is called during the startup of every
	domain (as long as security_driver != "none"), and it will propogate
	the error from virStorageFileGetMetadata, causing the domain startup
	to fail. This is, however, a common scenario when qemu is run as a
	non-root user and the disk image is stored on NFS.

	Ignoring this failure (which doesn't matter in this case, since the
	next thing done by SELinuxSetSecurityImageLabel - setting the file
	context - will also fail (and that function already ignores failures
	due to root-squash NFS) will allow us to continue bringing up the
	domain. The result is that we don't need to disable the entire
	security driver just because a domain's disk image is stored on
	root-squashed NFS.

	Don't use virFileReadLimFD in qemuDomainRestore.
	virFileReadLimFD is a poor fit for reading the header
	of the restore file.  The problem is that virFileReadLimFD
	returns an error when there is more data after the amount
	you ask to read, but that is *expected* in this case.

	This patch is essentially a revert of
	1a4d5c9543641c444dccd682f6256ee3faf22a80, but I don't think
	that commit does what it says anyway.  It purports to prevent
	an unwarranted OOM error, but since virFileReadLimFD will
	allocate memory up to the maximum anyway, the upper limit
	on the total amount of memory allocated is the same for either
	the old version or the new version.  Since the old saferead
	actually works and virFileReadLimFD does not, revert to
	using saferead.

	  VIR_DOMAIN_EVENT_SUSPENDED_IOERROR
	  VIR_DOMAIN_EVENT_SUSPENDED_WATCHDOG

	This also fixes a bug in the UML driver, that always returned 0
	as version number.

	Introduce STRSKIP to check if a string has a certain prefix and
	to skip this prefix.

	Replace sscanf in nwfilter rule parsing
	Parsing is stricter now and doesn't accept trailing characters
	after the actual value anymore.

	Replace sscanf in legacy device address parsing
	Parsing is stricter now and doesn't accept trailing characters
	after the actual <domain>:<bus>:<slot> sequence anymore.

2010-04-01  Stefan Berger  <stefanb@us.ibm.com>

	While writing a couple of test cases for the nwfilter's XML parser I found some cases where the output ended up not looking as expected. So the following changes are in the patch below:
	- if the protocol ID in the MAC header is an integer, just write it into
	the datastructure without trying to find a corresponding string for it
	and if none is found failing
	- when writing the protocol ID as string, simply write it as integer if
	no corresponding string can be found
	- same changes for arpOpcode parsing and printing
	- same changes for protocol ID in an IP packet
	- DSCP value needs to be written into the data structure
	- IP protocol version number is redundant at this level, so remove it
	- parse the protocol ID found inside an IP packet not only as string but
	also as uint8
	- arrange the display of the src and destination masks to be shown after
	the src and destination ip address respectively in the XML
	- the existing libvirt IP address parser accepts for example '25' as an
	IP address. I want this to be parsed as a CIDR type netmask. So try to
	parse it as an integer first (CIDR netmask) and if that doesn't work as
	a dotted IP address style netmask.
	- instantiation of rules with MAC masks didn't work because they weren't
	printed into a buffer, yet.

	ESX test case needs '/' in interface name
	To fix an ESX test case, valid interface names need '/' as valid letter.

	Use libvirt's existing ipv6/ipv4 parser/printer rather than self-written ones
	This patch changes the network filtering code to use libvirt's existing
	IPv4 and IPv6 address parsers/printers rather than my self-written ones.

	I am introducing a new function in network.c that counts the number of
	bits in a netmask and ensures that the given address is indeed a netmask,
	return -1 on error or values of 0-32 for IPv4 addresses and 0-128 for
	IPv6 addresses. I then based the function checking for valid netmask
	on invoking this function.

2010-03-30  Stefan Berger  <stefanb@us.ibm.com>

	Add ip6tables support for IPv6 filtering

	- ah-ipv6
	- sctp-ipv6
	- all-ipv6
	- icmpv6

	Many of the IPv4 data structure could be re-used for IPv6 support.
	Since ip6tables also supports pretty much the same command line parameters
	as iptables does, also much of the code could be re-used and now
	command lines are invoked with the ip(6)tables tool parameter passed
	through the functions as a parameter.

2010-03-30  Laine Stump  <laine@laine.org>

	Implement the qemu-kvm backend of clock timer elements
	Since the timers are defined to cover all possible config cases for
	several different hypervisors, many of these possibilities generate an
	error on qemu. Here is what is currently supported:

	RTC: If the -rtc commandline option is available, allow setting
	"clock=host"
	     or "clock=vm" based on the rtc timer clock='host|guest' value. Also
	     add "driftfix=slew" if the tickpolicy is 'catchup', or add nothing
	if
	     tickpolicy is 'delay'. (Other tickpolicies will raise an error).

	     If -rtc isn't available, but -rtc-td-hack is, add that option
	     if the tickpolicy is 'catchup', add -rtc-td-hack, if it is 'delay'
	     add nothing, and if it's anything else, raise an error.

	PIT: If -no-kvm-pit-reinjection is available, and tickpolicy is
	     'delay', add that option. if tickpolicy is 'catchup', do
	     nothing. Anything else --> raise an error.

	     If -no-kvm-pit-reinjection *isn't* available, but -tdf is, when
	     tickpolicy is 'catchup' add -tdf. If it's 'delay', do
	     nothing. Anything else --> raise an error.

	     If neither of those commandline options is available, and
	     tickpolicy is anything other than 'delay' (or unspecified), raise
	     an error.

	HPET: If -no-hpet flag is available and present='no', add -no-hpet.
	      If -no-hpet is not available, and present='yes', raise an error.
	      If present is unspecified, the default is to do whatever this
	      particular qemu does by default, so don't raise an error.

	All other timer types are unsupported by QEMU, so they will raise an
	error.

	* src/qemu/qemu_conf.c: extend qemuBuildClockArgStr() to generate the
	  command line arguments for the new options

2010-03-30  Laine Stump  <laine@laine.org>

	                        features indicated by each flag.
	* tests/qemuhelptest.c: add appropriate flags into the masks for each test

2010-03-30  Laine Stump  <laine@laine.org>

	Add timer element to domain schema
	timers are sub-elements of clocks. A clock can have zero or more
	instances of timer. Within the timer, only the name attribute is
	required; all other attributes are optional.

	A simpler representation of a timer element is:

	  <timer name='platform|pit|rtc|hpet|tsc'
	         wallclock='host|guest'
	         tickpolicy='delay|catchup|merge|discard'
	         frequency='123'
	         mode='auto|native|emulate|paravirt'
	         present='yes|no'/>

	frequency is a ulong. All other attributes are simple enums.

	Fix QEMU cpu affinity at startup to include all threads
	The QEMU cpu affinity is used in NUMA scenarios to ensure that
	guest memory is allocated from a specific node. Normally memory
	is allocate on demand in vCPU threads, but when using hugepages
	the initial thread leader allocates memory upfront. libvirt was
	not setting affinity of the thread leader, or I/O threads. This
	patch changes the code to set the process affinity in between
	the fork()/exec() of QEMU. This ensures that every single QEMU
	thread gets the affinity

	virsh: support VISUAL, and allow metacharacters in EDITOR
	Common Unix practice is to prefer VISUAL over EDITOR, particularly if
	the editor of choice spawns a new window.  Thus, it is also common to
	see settings like EDITOR='emacs -nw', with the expectation that the
	shell will parse this as an argument to 'emacs' and not try to invoke
	a file containing a space.

	If a user puts junk in EDITOR, they deserve what they get (much more
	than virsh will misbehave); furthermore, sudo scrubs EDITOR by
	default.  So the blind use of metacharacters in EDITOR should not be
	considered too much of a security issue.

	* tools/virsh.c (editFile): Prefer VISUAL over EDITOR.  Don't
	reject shell metacharacters in EDITOR.
	* tools/virsh.pod (edit, net-edit, ENVIRONMENT): Document VISUAL.

2010-03-30  Daniel Veillard  <veillard@redhat.com>

	Add hook utilities
	This exports 3 basic routines:
	  - virHookInitialize() initializing the hook support by looking for
	    scripts availability
	  - virHookPresent() used to test if there is a hook for a given driver
	  - virHookCall() which actually calls a synchronous script hook with
	    the needed parameters
	Note that this doesn't expose any public API except for the locations
	and arguments passed to the scripts

	* src/Makefile.am: add the 2 new files
	* src/util/hooks.h src/util/hooks.c: implements the 3 functions
	* src/libvirt_private.syms: export the 3 symbols internally

	Helper function for making a copy of virCPUDefPtr

2010-03-27  Jiri Denemark  <jdenemar@redhat.com>

	cpuUpdate() for updating guest CPU according to host CPU
	Useful mainly for migration. cpuUpdate changes guest CPU requirements in
	the following way:

	- match == "strict" || match == "exact"
	    - optional features which are supported by host CPU are changed into
	      required features
	    - optional features which are not supported by host CPU are disabled
	    - all other features remain untouched
	- match == "minimum"
	    - match is changed into "exact"
	    - optional features and all features not mentioned in guest CPU
	      specification which are supported by host CPU become required
	      features
	    - other optional features are disabled
	    - all other features remain untouched

	This ensures that no feature will suddenly disappear from the guest
	after migration.

2010-03-27  Jiri Denemark  <jdenemar@redhat.com>

	Don't replace persistent domain config with migrated config
	When a domain is defined on host1, migrated to host2 and then migrated
	back to host1, its current configuration would overwrite the libvirtd's
	in-memory copy of persistent configuration of that domain. This is not
	desired as we want to preserve the persistent configuration untouched.

	This patch introduces new 'live' parameter to virDomainAssignDef.
	Passing 'true' for 'live' means the configuration passed to
	virDomainAssignDef describes a configuration of live instance of the
	domain. This applies for saved domains which are being restored or for
	incoming domains during migration.

	All callers have been changed to pass the appropriate value.

	Add IPv6 support for the ebtables layer
	This patch adds IPv6 support for the ebtables layer. Since the parser
	etc. are all parameterized, it was fairly easy to add this...

	Add qemu support
	Add support for Qemu to have firewall rules applied and removed on VM
	startup and shutdown respectively. This  patch also provides support for
	the updating of a filter that causes all VMs that reference the filter
	to have their ebtables/iptables rules updated.

	Core driver implementation with ebtables support
	This patch implements the core driver and provides
	- management functionality for managing the filter XMLs
	- compiling the internal filter representation into ebtables rules
	- applying ebtables rules on a network (tap,macvtap) interface
	- tearing down ebtables rules that were applied on behalf of an
	interface
	- updating of filters while VMs are running and causing the firewalls to
	be rebuilt
	- other bits and pieces

	Add XML parser extensions for network filtering
	This patch adds XML processing for the network filter schema
	and extends the domain XML processing to parse the top level
	referenced filter along with potentially provided parameters

	Add virsh support for new CLI commands
	This patch adds virsh support for the five new CLI commands to manage
	network filters.

	Definition of the wire format, RPC client & server
	This patch adds the definition of the wire format for RPC calls
	and implementation of the RPC client & server code

	Implementation of the public API
	This patch adds the implementation of the public API for the network
	filtering (ACL) extensions to libvirt.c .

	Add internal API
	This patch adds the internal API extensions for network filtering (ACL) support.

	Add public API
	This patch adds extensions to libvirt's public API necessary for
	controlling the new functionality from remote for example.

	Add recursive locks
	This patch adds recursive locks necessary due to the processing of
	network filter XML that can reference other network filters, including
	references that cause looks. Loops in the XML are prevented but their
	detection requires recursive locks.

	Introduce a new virDomainUpdateDeviceFlags public API
	The current virDomainAttachDevice API can be (ab)used to change
	the media of an existing CDROM/Floppy device. Going forward there

2010-03-26  Daniel P. Berrange  <berrange@redhat.com>

	Add domain events for graphics network clients
	This introduces a new event type

	   VIR_DOMAIN_EVENT_ID_GRAPHICS

	The same event can be emitted in 3 scenarios

	  typedef enum {
	      VIR_DOMAIN_EVENT_GRAPHICS_CONNECT = 0,
	      VIR_DOMAIN_EVENT_GRAPHICS_INITIALIZE,
	      VIR_DOMAIN_EVENT_GRAPHICS_DISCONNECT,
	  } virDomainEventGraphicsPhase;

	Connect/disconnect are triggered at socket accept/close.
	The initialize phase is immediately after the protocol
	setup and authentication has completed. ie when the
	client is authorized and about to start interacting with
	the graphical desktop

	This event comes with *a lot* of potential information

	 - IP address, port & address family of client
	 - IP address, port & address family of server
	 - Authentication scheme (arbitrary string)
	 - Authenticated subject identity. A subject may have
	   multiple identities with some authentication schemes.
	   For example, vencrypt+sasl results in a x509dname
	   and saslUsername identities.

	This results in a very complicated callback :-(

	   typedef enum {
	      VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4,
	      VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV6,
	   } virDomainEventGraphicsAddressType;

	   struct _virDomainEventGraphicsAddress {
	       int family;
	       const char *node;
	       const char *service;
	   };
	   typedef struct _virDomainEventGraphicsAddress virDomainEventGraphicsAddress;
	   typedef virDomainEventGraphicsAddress *virDomainEventGraphicsAddressPtr;

	   struct _virDomainEventGraphicsSubject {
	      int nidentity;
	      struct {
	          const char *type;
	          const char *name;
	      } *identities;
	   };
	   typedef struct _virDomainEventGraphicsSubject virDomainEventGraphicsSubject;
	   typedef virDomainEventGraphicsSubject *virDomainEventGraphicsSubjectPtr;

	   typedef void (*virConnectDomainEventGraphicsCallback)(virConnectPtr conn,
	                                                         virDomainPtr dom,
	                                                         int phase,
	                                                         virDomainEventGraphicsAddressPtr local,
	                                                         virDomainEventGraphicsAddressPtr remote,
	                                                         const char *authScheme,
	                                                         virDomainEventGraphicsSubjectPtr subject,
	                                                         void *opaque);

	The wire protocol is similarly complex

	   struct remote_domain_event_graphics_address {
	     int family;
	     remote_nonnull_string node;
	     remote_nonnull_string service;
	   };

	   const REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX = 20;

	   struct remote_domain_event_graphics_identity {
	     remote_nonnull_string type;
	     remote_nonnull_string name;
	   };

	   struct remote_domain_event_graphics_msg {
	     remote_nonnull_domain dom;
	     int phase;
	     remote_domain_event_graphics_address local;
	     remote_domain_event_graphics_address remote;
	     remote_nonnull_string authScheme;
	     remote_domain_event_graphics_identity subject<REMOTE_DOMAIN_EVENT_GRAPHICS_IDENTITY_MAX>;
	   };

	This is currently implemented in QEMU for the VNC graphics
	protocol, but designed to be usable with SPICE graphics in
	the future too.

	Add support for an explicit IO error event
	This introduces a new event type

	   VIR_DOMAIN_EVENT_ID_IO_ERROR

	This event includes the action that is about to be taken
	as a result of the watchdog triggering

	  typedef enum {
	     VIR_DOMAIN_EVENT_IO_ERROR_NONE = 0,
	     VIR_DOMAIN_EVENT_IO_ERROR_PAUSE,

	  } virDomainEventIOErrorAction;

	In addition it has the source path of the disk that had the
	error and its unique device alias. It does not include the
	target device name (/dev/sda), since this would preclude
	triggering IO errors from other file backed devices (eg
	serial ports connected to a file)

	Thus there is a new callback definition for this event type

	typedef void (*virConnectDomainEventIOErrorCallback)(virConnectPtr conn,

	Add support for an explicit  RTC change event
	This introduces a new event type

	   VIR_DOMAIN_EVENT_ID_RTC_CHANGE

	This event includes the new UTC offset measured in seconds.

	Add support for an explicit guest reboot event
	The reboot event is not a normal lifecycle event, since the
	virtual machine on the host does not change state. Rather the
	guest OS is resetting the virtual CPUs. ie, the QEMU process
	does not restart. Thus, this does not belong in the current
	lifecycle events callback.

	This introduces a new event type

	    VIR_DOMAIN_EVENT_ID_REBOOT

	use the generic callback signature.

2010-03-26  Daniel P. Berrange  <berrange@redhat.com>

	Remote driver & daemon impl of new event API
	This wires up the remote driver to handle the new events APIs.
	The public API allows an application to request a callback filters
	events to a specific domain object, and register multiple callbacks
	for the same event type. On the wire there are two strategies for
	this

	 - Register multiple callbacks with the remote daemon, each
	   with filtering as needed
	 - Register only one callback per event type, with no filtering

	Both approaches have potential inefficiency. In the first scheme,
	the same event gets sent over the wire many times if multiple
	callbacks are registered. With the second scheme, unneccessary
	events get sent over the wire if a per-domain filter is set on
	the client. The second scheme is far easier to implement though,
	so this patch takes that approach.

	* daemon/dispatch.h: Don't export remoteRelayDomainEvent since it
	  is no longer needed for unregistering callbacks, instead the
	  unique callback ID is used
	* daemon/libvirtd.c, daemon/libvirtd.h: Track and unregister
	  callbacks based on callback ID, instead of function pointer
	* daemon/remote.c: Switch over to using virConnectDomainEventRegisterAny
	  instead of legacy virConnectDomainEventRegister function. Refactor
	  remoteDispatchDomainEventSend() to cope with arbitrary event types
	* src/driver.h, src/driver.c: Move verify() call into source file
	  instead of header, to avoid polluting the global namespace with
	  the verify function name
	* src/remote/remote_driver.c: Implement new APIs for event
	  registration. Refactor processCallDispatchMessage() to cope
	  with arbitrary incoming event types. Merge remoteDomainQueueEvent()
	  into processCallDispatchMessage() to avoid duplication of code.

	Add new internal domain events APIs for handling other event types
	The current internal domain events API tracks callbacks based on
	the function pointer, and only supports lifecycle events. This
	adds new internal APIs for registering callbacks for other event
	types. These new APIs are postfixed with the word 'ID' to indicate
	that they operated based on event ID, instead of hardcoded to
	lifecycle events

	* src/conf/domain_event.c, src/conf/domain_event.h,
	  src/libvirt_private.syms: Add new APIs for handling callbacks
	  for non-lifecycle events

2010-03-26  Daniel P. Berrange  <berrange@redhat.com>

	Refactor domain events to handle multiple event types
	The internal domain events APIs are designed to handle the lifecycle
	events. This needs to be refactored to allow arbitrary new event
	types to be handled.

	 * The signature of virDomainEventDispatchFunc changes to use
	   virConnectDomainEventGenericCallback instead of the lifecycle
	   event specific virConnectDomainEventCallback
	 * Every registered callback gains a unique ID to allow its
	   removal based on ID, instead of function pointer
	 * Every registered callback gains an 'eventID' to allow callbacks
	   for different types of events to be distinguished
	 * virDomainEventDispatch is adapted to filter out callbacks
	   whose eventID does not match the eventID of the event being
	   dispatched
	 * virDomainEventDispatch is adapted to filter based on the
	   domain name and uuid, if this filter is set for a callback.
	 * virDomainEvent type/detail fields are moved into a union to
	   allow different data fields for other types of events to be
	   added later

	* src/conf/domain_event.h, src/conf/domain_event.c: Refactor
	  to allow handling of different types of events
	* src/lxc/lxc_driver.c, src/qemu/qemu_driver.c,
	  src/remote/remote_driver.c, src/test/test_driver.c,
	  src/xen/xen_driver.c: Change dispatch function signature
	  to use virConnectDomainEventGenericCallback

2010-03-26  Daniel P. Berrange  <berrange@redhat.com>

	Make internal domain events struct definitions private
	The virtual box driver was directly accesing the domain events
	structs instead of using the APIs provided. To prevent this kind
	of abuse, make the struct definitions private, forcing use of the
	internal APIs. This requires adding one extra internal API.

	* src/conf/domain_event.h, src/conf/domain_event.c: Move
	  virDomainEventCallback and virDomainEvent structs into
	  the source file instead of header
	* src/vbox/vbox_tmpl.c: Use official APIs for dispatching domain
	  events instead of accessing structs directly.

2010-03-26  Daniel P. Berrange  <berrange@redhat.com>

	Introduce a new public API for domain events
	The current API for domain events has a number of problems

	 - Only allows for domain lifecycle change events
	 - Does not allow the same callback to be registered multiple times
	 - Does not allow filtering of events to a specific domain

	This introduces a new more general purpose domain events API

	  typedef enum {
	     VIR_DOMAIN_EVENT_ID_LIFECYCLE = 0,       /* virConnectDomainEventCallback */
	      ...more events later..
	  }

	  int virConnectDomainEventRegisterAny(virConnectPtr conn,
	                                       virDomainPtr dom, /* Optional, to filter */
	                                       int eventID,
	                                       virConnectDomainEventGenericCallback cb,
	                                       void *opaque,
	                                       virFreeCallback freecb);

	  int virConnectDomainEventDeregisterAny(virConnectPtr conn,
	                                         int callbackID);

	Since different event types can received different data in the callback,
	the API is defined with a generic callback. Specific events will each
	have a custom signature for their callback. Thus when registering an

	tests: Don't add extra padding if counter mod 40 is 0
	This change only affects the output of tests that have an exact
	multiple of 40 test cases. For example the domainschematest currently:

	TEST: domainschematest
	      ........................................ 40
	      ........................................ 80
	      ........................................ 120
	      ........................................ 160
	      ........................................                                         200 OK
	PASS: domainschematest

	It outputs additional 40 spaces on the last line.

	The domainschematest output is fixed by the change in test-lib.sh. The
	change in testutils.c fixes this for tests written in C. Currently no
	C test has an exact multiple of 40 test cases, but I checked it and
	the same problem exists there.

	This patch stops that in both cases.

	Allow suspend during live migration
	Currently no command can be sent to a qemu process while another job is
	active. This patch adds support for signaling long-running jobs (such as
	migration) so that other threads may request predefined operations to be
	done during such jobs. Two signals are defined so far:
	    - QEMU_JOB_SIGNAL_CANCEL
	    - QEMU_JOB_SIGNAL_SUSPEND

	The first one is used by qemuDomainAbortJob.

	The second one is used by qemudDomainSuspend for suspending a domain
	during migration, which allows for changing live migration into offline
	migration. However, there is a small issue in the way qemudDomainSuspend
	is currently implemented for migrating domains. The API calls returns
	immediately after signaling migration job which means it is asynchronous
	in this specific case.

	the qemuDriverLock to be held when it's called.  This
	patch does the simple thing and moves the qemuDriveUnlock
	to the end of the qemudDomainCoreDump so that the driver
	lock is held for the entirety of the call (as it is done
	in qemudDomainSave).  We will probably want to make the
	lock more fine-grained than that in the future, but
	we can fix both qemudDomainCoreDump and qemudDomainSave
	at the same time.

	Make sure qemudDomainSetVcpus doesn't hang.
	The code to add job support into libvirtd caused a problem
	in qemudDomainSetVcpus.  In particular, a qemuDomainObjEndJob()
	call was added at the end of the function, but a
	corresponding qemuDomainObjBeginJob() was not.  Additionally,
	a call to qemuDomainObj{Enter,Exit}Monitor() was also missed
	in qemudDomainHotplugVcpus().  These missing calls conspired to
	cause a hang in the libvirtd process after the command was
	finished.  Fix this by adding the missing calls.

	Remove qemudDomainSetMaxMemory.
	As previously discussed[1], this patch removes the
	qemudDomainSetMaxMemory() function, since it doesn't
	work.  This means that instead of getting somewhat
	cryptic errors, you will now get:

	error: Unable to change MaxMemorySize
	error: this function is not supported by the hypervisor: virDomainSetMaxMemory

	Which describes the situation perfectly.

	Get thread and socket information in virsh nodeinfo.
	The current code for "nodeinfo" is pretty naive
	about socket and thread information.  To determine the
	sockets, it just takes the number of cpus and divides
	by the number of cores.  For the thread count, it always
	sets it to 1.  With more recent Intel machines, however,
	hyperthreading is again an option, meaning that these
	heuristics no longer work and give bogus numbers.  This
	patch goes through /sys to get the additional
	information so we properly report it.

	Note that I had to edit the tests not to report on
	socket and thread counts, since these are determined
	dynamically now.

	Fix USB passthrough based on product/vendor
	Changeset

	  commit 5073aa994af460e775cb3e548528e28d7660fcc8
	  Author: Cole Robinson <crobinso@redhat.com>
	  Date:   Mon Jan 11 11:40:46 2010 -0500

	Added support for product/vendor based passthrough, but it only
	worked at the security driver layer. The main guest XML config
	was not updated with the resolved bus/device ID. When the QEMU
	argv refactoring removed use of product/vendor, this then broke
	launching guests.

	THe solution is to move the product/vendor resolution up a layer
	into the QEMU driver. So the first thing QEMU does is resolve
	the product/vendor to a bus/device and updates the XML config
	with this info. The rest of the code, including security drivers
	and QEMU argv generated can now rely on bus/device always being
	set.

	* src/util/hostusb.c, src/util/hostusb.h: Split vendor/product
	  resolution code out of usbGetDevice and into usbFindDevice.
	  Add accessors for bus/device ID
	* src/security/virt-aa-helper.c, src/security/security_selinux.c,
	  src/qemu/qemu_security_dac.c: Remove vendor/product from the
	  usbGetDevice() calls
	* src/qemu/qemu_driver.c: Use usbFindDevice to resolve vendor/product
	  into a bus/device ID

	Tweak container initialization to make upstart/init happier
	Upstart crashes & burns in a heap if $TERM environment variable
	is missing. Presumably the kernel always sets this when booting
	init on a real machine, so libvirt should set it for containers
	too.

	To make a typical inittab / mingetty setup happier, we need to
	symlink the primary console /dev/pts/0 to /dev/tty1.

	Misc fixes for LXC cgroups setup
	When using the 'ns' cgroup controller, the moment a process calls
	'unshare(CLONE_NEWNS)', it will be given a private cgroup tree
	under its current location. This really messages up the LXC
	controller process, because it ends up creating the containers'
	cgroup in the wrong place. The fix is fairly easy, just move
	the cgroup setup before the code which calls unshare(). The
	'ns' controller will still create extra undesired cgroups, but
	they at least won't break libvirt's setup now.

	The patch also adds a missing cgroups allow rule for /dev/tty
	device node

2010-03-05  Daniel P. Berrange  <berrange@redhat.com>

	Avoid creating top level cgroups if just querying for existance
	When getting the driver/domain cgroup it is possible to specify

	Change default for storage uid/gid from getuid()/getgid() to -1/-1
	This allows the config to have a setting that means "leave it alone",
	eg when building a pool where the directory already exists the user
	may want the current uid/gid of the directory left intact. This
	actually gets us back to older behavior - before recent changes to the
	pool building code, we weren't as insistent about honoring the uid/gid
	settings in the XML, and virt-manager was taking advantage of this
	behavior.

	As a side benefit, removing calls to getuid/getgid from the XML
	parsing functions also seems like a good idea. And having a default
	that is different from a common/useful value (0 == root) is a good
	thing in general, as it removes ambiguity from decisions (at least one
	place in the code was checking for (perms.uid == 0) to see if a
	special uid was requested).

	Note that this will only affect newly created pools and volumes. Due
	to the way that the XML is parsed, then formatted for newly created
	volumes, all existing pools/volumes already have an explicit uid and
	gid set.

	src/conf/storage_conf.c: Remove calls to setuid/setgid for default values
	                         of uid/gid, and set them to -1 instead

	Support VCPU hotplug in QEMU guests
	QEMU has a monitor command 'set_cpu' which allows a specific
	CPU to be toggled between online& offline state. libvirt CPU
	hotplug does not work in terms of individual indexes CPUs.

	Add a define for NFS_SUPER_MAGIC
	Commit 3c12a67b766cce51b47861ccde2be41de369f832 added
	a dependency on the NFS_SUPER_MAGIC macro, which is
	defined in linux/magic.h.  Unfortunately linux/magic.h
	is not available in RHEL-5, and causes a compile error.
	Just define it locally, since this is something that

	Make domain save work on root-squash NFS
	Move *all* file operations related to creation and writing of libvirt
	header to the domain save file into a hook function that is called by
	virFileOperation. First try to call virFileOperation as root. If that
	fails with EACCESS, and (in the case of Linux) statfs says that we're
	trying to save the file on an NFS share, rerun virFileOperation,
	telling it to fork a child process and setuid to the qemu user. This
	is the only way we can successfully create a file on a root-squashed
	NFS server.

	This patch (along with setting dynamic_ownership=0 in qemu.conf)
	makes qemudDomainSave work on root-squashed NFS.

	* src/qemu/qemu_driver.c: provide new qemudDomainSaveFileOpHook()
	  utility, use it in qemudDomainSave() if normal creation of the
	  file as root failed, and after checking the filesystem type for
	  the storage is NFS. In that case we also bypass the security
	  driver, as this would fail on NFS.

2010-03-03  Laine Stump  <laine@laine.org>

	Fix domain restore for files on root-squash NFS
	If qemudDomainRestore fails to open the domain save file, create a
	pipe, then fork a process that does setuid(qemu_user) and opens the
	file, then reads this file and stuffs it into the pipe. the parent
	libvirtd process will use the other end of the pipe as its fd, then
	reap the child process after it's done reading.

	This makes domain restore work on a root-squash NFS share that is only
	visible to the qemu user.

	* src/qemu/qemu_driver.c: add new qemudOpenAsUID() helper function,
	  and use it in qemudDomainRestore() if reading as root directly failed.

2010-03-03  Daniel P. Berrange  <berrange@redhat.com>

	Fix USB/PCI device address aliases in QEMU hotplug driver

2010-03-03  Daniel P. Berrange  <berrange@redhat.com>

	Fix detection of errors in QEMU device_add command
	The code assumed that 'device_add' returned an empty string upon
	success. This is not true, it sometimes prints random debug info.
	THus we need to check for an explicit fail string

	* src/qemu/qemu_monitor_text.c: Fix error checking of the device_add

	Introduce public API for cancelling async domain jobs
	The new virDomainAbortJob() method provides a way for a second
	thread to abort an ongoing job run by another thread. This
	extends to any API with  which the virDomainGetJobInfo() API
	is intended to work. Cancellation is not guarenteed, rather best

	* include/libvirt/libvirt.h.in: Define virDomainAbortJob()

2010-03-03  Daniel P. Berrange  <berrange@redhat.com>

	Add QEMU driver support for job info on migration ops
	Introduce support for  virDomainGetJobInfo in the QEMU driver. This
	allows for monitoring of any API that uses the 'info migrate' monitor
	command. ie virDomainMigrate, virDomainSave and virDomainCoreDump

	Unfortunately QEMU does not provide a way to monitor incoming migration
	so we can't wire up virDomainRestore yet.

	The virsh tool gets a new command 'domjobinfo' to query status

	* src/qemu/qemu_driver.c: Record virDomainJobInfo and start time

	Introduce public API for domain async job handling
	Introduce a new public API that provides a way to get progress

	are initially within scope of this idea are

	 virDomainMigrate
	 virDomainMigrateToURI
	 virDomainSave
	 virDomainRestore
	 virDomainCoreDump

	These all take a potentially long time and benefit from monitoring.
	The virDomainJobInfo struct allows for various pieces of information

	Fix PCI address handling when controllers are deleted
	* src/qemu/qemu_driver.c: in qemudDomainDetachPciControllerDevice()
	  when a controller is not present in the system anymore, the PCI
	  address must be deleted from libvirt's hashtable because it can
	  be re-used for other purposes.

	Fix data structure handling when controllers are attached
	* src/qemu/qemu_driver.c: in qemudDomainAttachDevice(), one must not
	  delete the data part when the operation succeeds because it is
	  required later on. The correct pattern to handlethe parsed
	  representation of the device information on success
	  is dev->data.controller = NULL; virDomainDeviceDefFree(dev);,
	  which leaves the structure pointed at by data in memory.

	Support variable clock offset mode in QEMU
	This allows QEMU guests to be started with an arbitrary clock

	remote: Improve daemon startup error reporting
	If I toggle enable_tcp in libvirtd.conf and add --listen in
	/etc/init.d/libvirtd, I get the unhelpful error:

	Starting libvirtd daemon: error: Unable to initialize network sockets.

	Running without --daemon provides much more useful info:

	sudo libvirtd --listen
	11:29:26.117: error : remoteCheckCertFile:270 : Cannot access CA certificate '/etc/pki/CA/cacert.pem': No such file or directory

	The daemon architecture makes it difficult to report this useful

	Ignore SIGWINCH in remote client call to poll(2) (RHBZ#567931).
	In bug 567931 we found that virt-top would exit occasionally
	when the terminal window was resized.  Tracking this down it
	turned out that SIGWINCH was being delivered to the process at
	exactly the point where the libvirt remote driver was calling
	poll(2) waiting for a reply from libvirtd.

	This caused the poll(2) call to be interrupted (returning errno
	EINTR).  However handling EINTR the same way as EAGAIN was not
	the solution to this problem since we found previously that this
	would break Ctrl-C handling (commit 47fec8eac2bb3).

	The correct solution is to mask out SIGWINCH for the duration
	of the poll(2) system call.  The per-thread mask is changed and
	restored immediately after the call.  Since we are using
	pthread_sigmask, this should not affect other threads, and
	since we restore the signal mask immediately afterwards it should
	not affect the current thread visibly either.  Other possibly
	problematic signals are SIGCHLD and SIGPIPE and these are
	masked too.

	Note use of ignore_value: It's not fatal if we cannot mask out
	SIGWINCH, and in any case pthread_sigmask never fails on Linux
	as long as you supply the correct arguments.

	I tested this patch and it cures the original problem with
	virt-top.

	Fix daemon-conf invalid failures
	The daemon-conf test would fail on my system if there was a system libvirtd
	running.  In the course of troubleshooting that problem, I discovered that the
	daemon-conf script would always fail if run by itself because it found the line:

	\# that each "PARAMETER = VALUE" line in this file have the parameter

	which it mistook for a line containing a parameter.  I have changed the test to
	avoid mistaking a line containing \"PARAMETER = VALUE\" for a parameter line.

	The corrupted config tests turned out to be failing because the test daemon was
	discovering the pid file from the running daemon and exiting before it processed
	the test config file.  Specifying the pid file for the corrupt config tests in
	the same way as for the valid config test solved that problem.

2010-02-20  Laine Stump  <laine@laine.org>

	Use virFileOperation hook function in virStorageBackendFileSystemVolBuild
	There were a few operations on the storage volume file that were still
	being done as root, which will fail if the file is on a root-squashed
	NFS share. The result was that attempts to create a storage volume of
	type "raw" on a root-squashed NFS share would fail.

	This patch uses the newly introduced "hook" function in
	virFileOperation to execute all those file operations in the child
	process that's run under the uid that owns the file (and, presumably,
	has permission to write to the NFS share)

	* src/storage/storage_backend.c: use virFileOperation() in
	  virStorageBackendCreateRaw, turning virStorageBackendCreateRaw()
	  into a new createRawFileOpHook() hook

2010-02-20  Laine Stump  <laine@laine.org>

	Rename virFileCreate to virFileOperation, add hook function
	It turns out it is also useful to be able to perform other operations
	on a file created while running as a different uid (eg, write things
	to that file), and possibly to do this to a file that already
	exists. This patch adds an optional hook function to the renamed (for
	more accuracy of purpose) virFileOperation; the hook will be called
	after the file has been opened (possibly created) and gid/mode
	checked/set, before closing it.

	As with the other operations on the file, if the VIR_FILE_OP_AS_UID
	flag is set, this hook function will be called in the context of a
	child process forked from the process that called virFileOperation.
	The implication here is that, while all data in memory is available to
	this hook function, any modification to that data will not be seen by
	the caller - the only indication in memory of what happened in the
	hook will be the return value (which the hook should set to 0 on
	success, or one of the standard errno values on failure).

	Another piece of making the function more flexible was to add an
	"openflags" argument. This arg should contain exactly the flags to be
	passed to open(2), eg O_RDWR | O_EXCL, etc.

	In the process of adding the hook to virFileOperation, I also realized
	that the bits to fix up file owner/group/mode settings after creation
	were being done in the parent process, which could fail, so I moved
	them to the child process where they should be.

	* src/util/util.[ch]: rename and rework virFileCreate-->virFileOperation,
	  and redo flags in virDirCreate
	* storage/storage_backend.c, storage/storage_backend_fs.c: update the
	  calls to virFileOperation/virDirCreate to reflect changes in the API,
	  but don't yet take advantage of the hook.

	macvtap IFF_VNET_HDR configuration

	Use virFork() in __virExec(), virFileCreate() and virDirCreate()
	For __virExec() this is a semantic NOP except for when fork()
	fails. __virExec() would previously forget to restore the signal mask
	in this case; virFork() corrects this behavior.

	virFileCreate() and virDirCreate() gain the code to reset the logging
	and properly deal with the signal handling race condition.

	This also removes a log message that had a typo ("cannot fork o create
	file '%s'") - this error is now logged in a more generic manner in
	virFork() (more generic, but really just as informative, since the
	fact that it's forking to create a file is immaterial to the fact that
	it simply can't fork)

	* src/util/util.c: use the generic virFork() in the 3 functions

2010-02-19  Laine Stump  <laine@laine.org>

	Add virFork() function to utils
	virFork() contains bookkeeping that must be done any time a process
	forks. Currently this includes:

	1) Call virLogLock() prior to fork() and virLogUnlock() just after,
	   to avoid a deadlock if some other thread happens to hold that lock
	   during the fork.

	2) Reset the logging hooks and send all child process log messages to
	   stderr.

	3) Block all signals prior to fork(), then either a) reset the signal
	   mask for the parent process, or b) clear the signal mask for the
	   child process.

	Note that the signal mask handling in __virExec erroneously fails to
	restore the signal mask when fork() fails. virFork() fixes this
	problem.

	Other than this, it attempts to behave as closely to fork() as
	possible (including preserving errno for the caller), with a couple
	exceptions:

	1) The return value is 0 (success) or -1 (failure), while the pid is
	   returned via the pid_t* argument. Like fork(), if pid < 0 there is
	   no child process, otherwise both the child and the parent will
	   return to the caller, and both should look at the return value,
	   which will indicate if some of the extra processing outlined above
	   encountered an error.

	2) If virFork() returns with pid < 0 or with a return value < 0
	   indicating an error condition, the error has already been
	   reported. You can log an additional message if you like, but it
	   isn't necessary, and may be awkwardly extraneous.

	Note that virFork()'s child process will *never* call _exit() - if a
	child process is created, it will return to the caller.

	* util.c util.h: add virFork() function, based on what is currently
	                 done in __virExec().

	macvtap teardown rework
	Rework and simplification of teardown of the macvtap device.

	Basically all devices with the same MAC address and link device are kept
	alive and not attempted to be torn down. If a macvtap device linked to a
	physical interface with a certain MAC address 'M' is to be created it
	will automatically fail if the interface is 'up'ed and another macvtap
	with the same properties (MAC addr 'M', link dev) happens to be 'up'.
	This will prevent the VM from starting or the device from being attached
	to a running VM. Stale interfaces are assumed to be there for some
	reason and not stem from libvirt.

	In the VM shutdown path, it's assuming that an interface name is always
	available so that if the device type is DIRECT it can be torn down
	using its name.

	qemu: Make SetVcpu command hotplug only
	Similar to the Set*Mem commands, this implementation was bogus and
	misleading. Make it clear this is a hotplug only operation, and that the
	hotplug piece isn't even implemented.

	Also drop the overkill maxvcpus validation: we don't perform this check
	at XML define time so clearly no one is missing it, and there is
	always the risk that our info will be out of date, possibly preventing
	legitimate CPU values.

2010-02-17  Cole Robinson  <crobinso@redhat.com>

	qemu: Make Set*Mem commands hotplug only
	SetMem and SetMaxMem are hotplug only APIs, any persistent config
	changes are supposed to go via XML definition. The original implementation
	of these calls were incorrect and had the nasty side effect of making
	a psuedo persistent change that would be lost after libvirtd restart
	(I didn't know any better).

	Fix these APIs to rightly reject non running domains.

	Make error reporting for QEMU JSON mode more friendly
	Current error reporting for JSON mode returns the full JSON
	command string and full JSON error string. This is not very
	user friendly, so this change makes the error report only
	contain the basic command name, and friendly error message
	description string. The full JSON data is logged instead.

	* src/qemu/qemu_monitor_json.c: Always return the 'desc' field from

2010-02-16  Daniel P. Berrange  <berrange@redhat.com>

	Run 'qmp_capabilities' command at QEMU monitor startup
	When in JSON mode, QEMU requires that 'qmp_capabilities' is run as

	Convert virSecurityReportError into a macro
	The virRaiseError macro inside of virSecurityReportError expands to

	information. But this three values are always the same for every call
	to virSecurityReportError and do not reflect the actual error context.

	Add persistence of PCI addresses to QEMU
	Current PCI addresses are allocated at time of VM startup.
	To make them truely persistent, it is neccessary to do this

	Fix <cpu> element in domain XML schema
	The current schema is more permissive than the XML parsing code in

	- <cpu> element without 'match' attribute is allowed only if <topology>

	Fix disk stats retrieval with QEMU >= 0.12
	With QEMU >= 0.12 the host and guest side of disks no longer have
	the same naming convention. Specifically the host side will now
	get a 'drive-' prefix added to its name. The 'info blockstats'
	monitor command returns the host side name, so it is neccessary
	to strip this off when looking up stats since libvirt stores the
	guest side name !

	* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Move 'drive-' prefix
	  string to a defined constant
	* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_text.c: Strip

	qemu: Increase guest startup timeout to 30 seconds
	Currently the timeout for reading startup output is 3 seconds. If the
	host is under any sort of load, we can easily trigger this. Lets bump
	it to 30 seconds.

	Since the polling loop checks to see if the process has died, we shouldn't
	erroneously hit this timeout if qemu bombs (only if it is stuck in some
	infinite loop).

	Another fork() log locking cleanup in file creation

	Fix log locking problem when using fork() in the library
	Ad pointed out by Dan Berrange:
	So if some thread in libvirtd is currently executing a logging call,
	while another thread calls virExec(), that other thread no longer
	exists in the child, but its lock is never released. So when the
	child then does virLogReset() it deadlocks.

	The only way I see to address this, is for the parent process to call
	virLogLock(), immediately before fork(), and then virLogUnlock()
	afterwards in both parent & child. This will ensure that no other
	thread
	can be holding the lock across fork().

	* src/util/logging.[ch] src/libvirt_private.syms: export virLogLock() and
	  virLogUnlock()
	* src/util/util.c: lock just before forking and unlock just after - in
	  both parent and child.

	Remove direct storage of hostnet_name & vlan
	The current way of assigning names to the host network backend and
	NIC device in QEMU was over complicated, by varying naming scheme
	based on the NIC model and backend type. This simplifies the naming
	to simply be 'net0' and 'hostnet0', allowing code to easily determine
	the host network name and vlan based off the primary device alias
	name 'net0'. This in turn allows removal of alot of QEMU specific
	code from the XML parser, and makes it easier to assign new unique
	names for NICs that are hotplugged

	* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove hostnet_name
	  and vlan fields from virNetworkDefPtr
	* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c:

	Assign PCI addresses before hotplugging devices
	PCI disk, disk controllers, net devices and host devices need to
	have PCI addresses assigned before they are hot-plugged

	* src/qemu/qemu_conf.c: Add APIs for ensuring a device has an
	  address and releasing unused addresses
	* src/qemu/qemu_driver.c: Ensure all devices have addresses
	  when hotplugging.

2010-02-03  Daniel P. Berrange  <berrange@redhat.com>

	Rewrite way QEMU PCI addresses are allocated
	The current QEMU code allocates PCI addresses incrementally starting
	at 4. This is not satisfactory because the user may have given some
	addresses in their XML config, which need to be skipped over when
	allocating addresses to remaining devices.

	It is thus neccessary to maintain a list of already allocated PCI
	addresses and then only allocate ones that remain unused. This is
	also required for domain device hotplug to work properly later.

	* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
	  list of existing PCI addresses, and allocating new addresses.
	  Refactor address assignment to use this code
	* src/qemu/qemu_driver.c: Pull PCI address assignment up into the

	  whereever possible

2010-02-03  Daniel P. Berrange  <berrange@redhat.com>

	Introduce internal QEMU monitor APIs for drive + device hotadd
	The way QEMU is started has been changed to use '-device' and

	udev: Don't let strtoul parse USB busnum and devnum as octal
	udevGetUintProperty was called with base set to 0 for busnum and devnum.
	With base 0 strtoul parses the number as octal if it start with a 0. But
	busnum and devnum are decimal and udev returns them padded with leading

	Cleanup of large buffer on stack in virFileMakePath
	virFileMakePath is a recursive function that was creates a buffer
	PATH_MAX bytes long for each recursion (one recursion for each element
	in the path). This changes it to have no buffers on the stack, and to
	allocate just one buffer total, no matter how many elements are in the
	path. Because the modified algorithm requires a char* to be passed in
	rather than const char *, it is now 2 functions - a toplevel API

	Certain hypervisors (like qemu/kvm) map the PCI bar(s) on
	the host when doing device passthrough.  This can lead to a race
	condition where the hypervisor is still cleaning up the device while
	libvirt is trying to re-attach it to the host device driver.  To avoid
	this situation, we look through /proc/iomem, and if the hypervisor is
	still holding onto the bar (denoted by the string in the matcher variable),
	then we can wait around a bit for that to clear up.

	v2: Thanks to review by DV, make sure we wait the full timeout per-device

	Fix device assignment with root devices
	The patches to add ACS checking to PCI device passthrough
	introduced a bug.  With the current code, if you try to
	passthrough a device on the root bus (i.e. bus 0), then
	it denies the passthrough.  This is because the code in
	pciDeviceIsBehindSwitchLackingACS() to check for a parent
	device doesn't take into account the possibility of the
	root bus.  If we are on the root bus, it means we
	legitimately can't find a parent, and it also means that
	we don't have to worry about whether ACS is enabled.
	Therefore return 0 (indicating we don't lack ACS) from
	pciDeviceIsBehindSwitchLackingACS().

	Add a rule to check for uses of readlink.

	Use virFileResolveLink instead of readlink in AppArmor

	Fix security driver calls in hotplug cleanup paths
	The hotplug code was not correctly invoking the security driver
	in error paths. If a hotplug attempt failed, the device would

	Fix leak of allocated security label
	If a VM fails to start, we can't simply free the security label
	strings, we must call the domainReleaseSecurityLabel() method
	otherwise the reserved 'mcs' level will be leaked in SElinux

	* src/qemu/qemu_driver.c: Invoke domainReleaseSecurityLabel()
	  when domain fails to start

2010-01-21  Daniel P. Berrange  <berrange@redhat.com>

	Refactor setup & cleanup of security labels in security driver
	The current security driver architecture has the following
	split of logic

	 * domainGenSecurityLabel

	    Allocate the unique label for the domain about to be started

	 * domainGetSecurityLabel

	    Retrieve the current live security label for a process

	 * domainSetSecurityLabel

	    Apply the previously allocated label to the current process
	    Setup all disk image / device labelling

	 * domainRestoreSecurityLabel

	    Restore the original disk image / device labelling.
	    Release the unique label for the domain

	The 'domainSetSecurityLabel' method is special because it runs
	in the context of the child process between the fork + exec.

	This is require in order to set the process label. It is not
	required in order to label disks/devices though. Having the
	disk labelling code run in the child process limits what it
	can do.

	In particularly libvirtd would like to remember the current
	disk image label, and only change shared image labels for the
	first VM to start. This requires use & update of global state
	in the libvirtd daemon, and thus cannot run in the child
	process context.

	The solution is to split domainSetSecurityLabel into two parts,
	one applies process label, and the other handles disk image
	labelling. At the same time domainRestoreSecurityLabel is
	similarly split, just so that it matches the style. Thus the
	previous 4 methods are replaced by the following 6 new methods

	 * domainGenSecurityLabel

	    Allocate the unique label for the domain about to be started
	    No actual change here.

	 * domainReleaseSecurityLabel

	   Release the unique label for the domain

	 * domainGetSecurityProcessLabel

	   Retrieve the current live security label for a process
	   Merely renamed for clarity.

	 * domainSetSecurityProcessLabel

	   Apply the previously allocated label to the current process

	 * domainRestoreSecurityAllLabel

	    Restore the original disk image / device labelling.

	 * domainSetSecurityAllLabel

	    Setup all disk image / device labelling

	The SELinux and AppArmour drivers are then updated to comply with
	this new spec. Notice that the AppArmour driver was actually a
	little different. It was creating its profile for the disk image
	and device labels in the 'domainGenSecurityLabel' method, where as
	the SELinux driver did it in 'domainSetSecurityLabel'. With the
	new method split, we can have consistency, with both drivers doing
	that in the domainSetSecurityAllLabel method.

	NB, the AppArmour changes here haven't been compiled so may not
	build.

2010-01-21  Daniel P. Berrange  <berrange@redhat.com>

	Make security drivers responsible for checking dynamic vs static labelling
	The QEMU driver is doing 90% of the calls to check for static vs
	dynamic labelling. Except it is forgetting todo so in many places,
	in particular hotplug is mistakenly assigning disk labels. Move
	all this logic into the security drivers themselves, so the HV
	drivers don't have to think about it.

	* src/security/security_driver.h: Add virDomainObjPtr parameter
	  to virSecurityDomainRestoreHostdevLabel and to
	  virSecurityDomainRestoreSavedStateLabel
	* src/security/security_selinux.c, src/security/security_apparmor.c:
	  Add explicit checks for VIR_DOMAIN_SECLABEL_STATIC and skip all

	  or VIR_DOMAIN_SECLABEL_DYNAMIC. Add missing checks for possibly NULL

	Create storage pool directories with proper uid/gid/mode
	Previously the uid/gid/mode in the xml was ignored when creating new
	storage pool directories. This commit attempts to honor the requested
	permissions, and spits out an error if it can't.

	Note that when creating the directory, the rest of the path leading up
	to the final element is created using current uid/gid/mode, and the
	final element gets the settings from xml. It is NOT an error for the
	directory to already exist; in this case, the perms for the existing
	directory are just set (if necessary).

	* src/storage/storage_backend_fs.c: update the virStorageBackendFileSystemBuild
	  function to check the directory hierarchy separately then create the
	  leaf directory with the right attributes

2010-01-21  Laine Stump  <laine@laine.org>

	Create storage volumes directly with desired uid/gid
	In order to avoid problems trying to chown files that were created by
	root on a root-squashing nfs server, fork a new process that setuid's
	to the desired uid before creating the file. (It's only done this way
	if the pool containing the new volume is of type 'netfs', otherwise
	the old method of creating the file followed by chown() is used.)

	This changes the semantics of the "create_func" slightly - previously
	it was assumed that this function just created the file, then the
	caller would chown it to the desired uid. Now, create_func does both
	operations.

	There are multiple functions that can take on the role of create_func:

	createFileDir - previously called mkdir(), now calls virDirCreate().
	virStorageBackendCreateRaw - previously called open(),
	                             now calls virFileCreate().
	virStorageBackendCreateQemuImg - use virRunWithHook() to setuid/gid.
	virStorageBackendCreateQcowCreate - same.
	virStorageBackendCreateBlockFrom - preserve old behavior (but attempt
	                                   chown when necessary even if not root)

	* src/storage/storage_backend.[ch] src/storage/storage_backend_disk.c
	  src/storage/storage_backend_fs.c src/storage/storage_backend_logical.c
	  src/storage/storage_driver.c: change the create_func implementations,
	  also propagate the pool information to be able to detect NETFS ones.

2010-01-21  Laine Stump  <laine@laine.org>

	New utility functions virFileCreate and virDirCreate
	These functions create a new file or directory with the given
	uid/gid. If the flag VIR_FILE_CREATE_AS_UID is given, they do this by
	forking a new process, calling setuid/setgid in the new process, and
	then creating the file. This is better than simply calling open then
	fchown, because in the latter case, a root-squashing nfs server would
	create the new file as user nobody, then refuse to allow fchown.

	If VIR_FILE_CREATE_AS_UID is not specified, the simpler tactic of
	creating the file/dir, then chowning is is used. This gives better
	results in cases where the parent directory isn't on a root-squashing
	NFS server, but doesn't give permission for the specified uid/gid to
	create files. (Note that if the fork/setuid method fails to create the
	file due to access privileges, the parent process will make a second
	attempt using this simpler method.)

	If the bit VIR_FILE_CREATE_ALLOW_EXIST is set in the flags, an
	existing file/directory will not cause an error; in this case, the
	function will simply set the permissions of the file/directory to
	those requested. If VIR_FILE_CREATE_ALLOW_EXIST is not specified, an
	existing file/directory is considered (and reported as) an error.

	Return from both of these functions is 0 on success, or the value of
	errno if there was a failure.

	* src/util/util.[ch]: add the 2 new util functions

2010-01-21  Laine Stump  <laine@laine.org>

	Add virRunWithHook util function
	* src/util/util.[ch]: similar to virExecWithHook, but waits for child to

	Make all bitfields unsigned ints to avoid unexpected values in casts
	The 'int virInterfaceIsActive()' method was directly returning the
	value of the 'int active:1' bitfield in virIntefaceDefPtr. A bitfield
	with a signed integer, will hold the values 0 and -1, not 0 and +1
	as might be expected. This meant that virInterfaceIsActive() was
	always returning -1 when the interface was active, not +1 & thus all
	callers thought an error had occurred. To protect against this kind
	of mistake again, change all bitfields to be unsigned ints

	Update interface.rng and xml test files to match netcf 0.1.5
	The RNG now supports IPv6 and bonds attached to bridges, along with
	some other minor tweaks. All test files from netcf have been copied to
	the test directory and added to the xml2xml and schema tests (and they
	all pass, of course ;-)

2010-01-20  Laine Stump  <laine@laine.org>

	Support bond interfaces attached to bridges in interface xml.
	This was accomplished in xml parsing by doing away with the
	stripped-down virInterfaceBareDef object, and just always using
	virInterfaceDef, but with restrictions in certain places (eg, the type
	of subordinate interface allowed in parsing depends on the parent
	interface).

	xml formatting was similarly adjusted. In addition, the formatting
	functions keep track of the level of interface nesting, and insert
	extra leading spaces on each line accordingly (using %*s).

	The only change in formatted xml from previous (aside frmo supporting
	new combinations of interface types) is that the subordinate ethernet
	interfaces take up 2 lines rather than one, eg:

	   <interface type='ethernet' name='eth0'>
	   </interface>

	instead of:

	   <interface type='ethernet' name='eth0'/>

	Allow for CPU topology specification without model
	Currently CPU topology may only be specified together with CPU model:

	Current version expects name=value,... list and when an incorrect string
	such as "a,b,c=d" would be parsed as "a,b,c" keyword with "d" value
	without reporting any error, which is probably not the expected
	behavior.

	This patch adds an extra argument called allowEmptyValue, which if
	non-zero will permit keywords with no value; "a,b=c,,d=" will be parsed
	as follows:
	    keyword value
	    "a"     NULL
	    "b"     "c"
	    ""      NULL
	    "d"     ""

	In case allowEmptyValue is zero, the string is required to contain
	name=value pairs only; retvalues is guaranteed to contain non-NULL
	pointers. Now, "a,b,c=d" will result in an error.

	Convert VirtIO balloon over to -device syntax
	Replace

	   -balloon virtio

	With

	   -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3

	This allows it to get correct assigned PCI address as declared in
	previous patch

	 * src/qemu/qemu_conf.c: Convert Virtio ballon to -device and
	   give it an explicit PCI address
	 * tests/qemuxml2argvdata/qemuxml2argv-*args: Add in virtio balloon
	   where appropriate

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Auto-assign PCI addresses
	Instead of relying on QEMU to assign PCI addresses and then querying
	them with 'info pci', manually assign all PCI addresses before starting
	the guest.  These addresses are not stable across reboots. That will
	come in a later patch

	NB, the PIIX3 (IDE, FDC, ISA-Bridge) will always have slot 1 and
	VGA will always have slot 2. We declare the Virtio Balloon gets
	slot 3, and then all remaining slots are for configured devices.

	* src/qemu/qemu_conf.c: If -device is supported, then assign all PCI
	  addresses when building the command line
	* src/qemu/qemu_driver.c: Don't query monitor for PCI addresses if
	  they have already been assigned
	* tests/qemuxml2argvdata/qemuxml2argv-hostdev-pci-address-device.args,
	  tests/qemuxml2argvdata/qemuxml2argv-net-virtio-device.args,

	Pass -vga none if no video card specified
	QEMU always configures a VGA card. If no video card is included in
	the libvirt XML, it is neccessary to explicitly turn off the default
	using -vga none

	* src/qemu/qemu_conf.c: Pass -vga none if no video card is configured
	* tests/qemuargv2xmltest.c, tests/qemuxml2argvtest.c: Test for
	  handling -vga none.
	* tests/qemuxml2argvdata/qemuxml2argv-nographics-vga.args,

	Add support for explicit -sdl flag to QEMU
	Not all QEMU builds default to SDL graphics for their display.
	Newer QEMU now has an explicit -sdl flag, which we can use to
	explicitly request SDL intead of relying on the default. This
	protects libvirt against unexpected changes in graphics default

	* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Probe for -sdl
	  flag and use it if it is found
	* tests/qemuhelptest.c: Add SDL flag to tests

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert guestfwd to -device, and add -sdl explicit args
	The old syntax was

	   -chardev SOMECONFIG
	   -nic user,guestfwd=tcp:IP:PORT-chardev:CHARDEV

	The new syntax is

	   -chardev SOMECONFIG
	   -netdev user,guestfwd=tcp:IP:PORT,chardev=ID,id=user-ID

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert PCI device assignment over to -device
	The old syntax is

	  -pcidevice host=BUS:SLOT:FUNCTION

	The new syntax is

	  -device pci-assign,host=BUS:SLOT:FUNCTION,addr=<PCI SLOT>,id=host0

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert USB input devices to -device

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert USB hostdevices over to -device
	The old syntax was

	   -usbdevice host:PRODUCT:VENDOR

	Or

	   -usbdevice host:BUS.DEV

	The new syntax is

	   -device usb-host,product=PRODUCT,vendor=VENDOR

	Or

	   -device usb-host,hostbus=BUS,hostaddr=DEV

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert USB disks over to -device
	The previous syntax was severely limited in its options

	  -usbdevice disk:/home/berrange/output.img

	The new syntax is the same as for other disk types

	  -drive file=/home/berrange/output.img,if=none,id=usb-1,index=1
	  -device usb-storage,drive=usb-1

	Again, the index= arg is wrong here, and will be removed in a
	later merge

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert NICs over to use -device & -netdev where possible
	The current syntax uses a pair of args

	   -net nic,macaddr=52:54:00:56:6c:55,vlan=3,model=pcnet,name=pcnet.0
	   -net user,vlan=3,name=user.0

	The new syntax does not  need the vlan craziness anymore, and
	so has a simplified pair of args

	   -netdev user,id=user.0
	   -device pcnet,netdev=user.0,id=pcnet.0,mac=52:54:00:56:6c:55,addr=<PCI SLOT>

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert disk drive over to use -device where available
	The current preferred syntax for disk drives uses

	  -drive file=/vms/plain.qcow,if=virtio,index=0,boot=on,format=qcow

	The new syntax splits this up into a pair of linked args

	  -drive file=/vms/plain.qcow,if=none,id=drive-virtio-0,format=qcow2
	  -device virtio-blk-pci,drive=drive-virtio-0,id=virtio-0,addr=<PCI SLOT>

	SCSI/IDE devices also get a bus property linking them to the
	controller

	  -device scsi-disk,drive=drive-scsi0-0-0,id=scsi0-0-0,bus=scsi0.0,scsi-id=0
	  -device ide-drive,drive=drive-ide0-0-0,id=ide0-0-0,bus=ide0,unit=0

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert audio devices over to -device syntax
	The current syntax for audio devices is a horrible multiplexed
	arg

	    -soundhw sb16,pcspk,ac97

	The new syntax is

	    -device sb16,id=sound0

	or

	    -device AC97,id=sound1,addr=<PCI SLOT>

	NB, pcspk still uses the old -soundhw syntax

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert watchdog to -device
	The current syntax for watchdogs is

	    -watchdog i6300esb

	The new syntax will now be

	    -device i6300esb,id=watchdogNN,addr=<PCI-SLOT>

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Convert character devices over to use -device
	The current character device syntax uses either

	  -serial tty,path=/dev/ttyS2

	Or

	  -chardev tty,id=serial0,path=/dev/ttyS2 -serial chardev:serial0

	With the new -device support, we now prefer

	  -chardev file,id=serial0,path=/tmp/serial.log -device isa-serial,chardev=serial0

	This patch changes the existing -chardev syntax to use this new
	scheme, and fallbacks to the old plain -serial syntax for old
	QEMU.

	The monitor device changes to

	  -chardev socket,id=monitor,path=/tmp/test-monitor,server,nowait -mon chardev=monitor

	In addition, this patch adds --nodefaults, which kills off the
	default serial, parallel, vga and nic devices. THis avoids the
	need for us to explicitly turn each off

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Assign device aliases for all devices at startup
	When starting a guest, give every device a unique alias. This will
	be used for the 'id' parameter in -device args in later patches.
	It can also be used to uniquely identify devices in the monitor

	For old QEMU without -device, assign disk names based on QEMU's
	historical naming scheme.

	* src/qemu/qemu_conf.c: Assign unique device aliases
	* src/qemu/qemu_driver.c: Remove obsolete qemudDiskDeviceName
	  and use the device alias in eject & blockstats commands

2010-01-18  Jim Meyering  <meyering@redhat.com>

	storage_backend_fs.c: do not ignore probe failure
	* src/storage/storage_backend_fs.c (virStorageBackendFileSystemRefresh):
	Correct parentheses.  The documented intent is to ignore non-regular
	files, yet due to a parenthesization error all errors were handled
	that way.

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Probe for -device and use -nodefaults
	Probe for the new -device flag and if available set the -nodefaults
	flag, instead of using -net none, -serial none or -parallel none.
	Other device types will be converted to use -device in later patches.
	The -nodefaults flag will help avoid unwelcome surprises from future
	QEMU releases

	* src/qemu/qemu_conf.c: Probe for -device. Add -nodefaults flag.
	  Remove -net none, -serial none or -parallel none
	* src/qemu/qemu_conf.h: Define QEMU_CMD_FLAG_DEVICE

	Add device info to serial, parallel, channel, input & fs devices
	Although the serial, parallel, chanel, input & fs devices do
	not have PCI address info, they can all have device aliases.
	Thus it neccessary to associate the virDomainDeviceInfo data
	with them all.

	* src/conf/domain_conf.c, src/conf/domain_conf.h: Add hooks for
	  parsing / formatting device info for serial, parallel, channel
	  input and fs devices.
	* docs/schemas/domain.rng: Associate device info with character
	  devices, input & fs device

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Introduce device aliases
	This patch introduces the support for giving all devices a short,
	unique name, henceforth known as a 'device alias'.  These aliases
	are not set by the end user, instead being assigned by the hypervisor
	if it decides it want to support this concept.

	The QEMU driver sets them whenever using the -device arg syntax
	and uses them for improved hotplug/hotunplug. it is the intent
	that other APIs (block / interface stats & device hotplug) be
	able to accept device alias names in the future.

	The XML syntax is

	   <alias name="video0"/>

	This may appear in any type of device that supports device info.

	* src/conf/domain_conf.c, src/conf/domain_conf.h: Add a 'alias'
	  field to virDomainDeviceInfo struct & parse/format it in XML
	* src/libvirt_private.syms: Export virDomainDefClearDeviceAliases
	* src/qemu/qemu_conf.c: Replace use of "nic_name" field with the
	  standard device alias
	* src/qemu/qemu_driver.c: Clear device aliases at shutdown

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Clear assigned PCI devices at shutdown
	The PCI device addresses are only valid while the VM is running,
	since they are auto-assigned by QEMU. After shutdown they must
	all be cleared. Future QEMU driver enhancement will allow for
	persistent PCI address assignment

	* src/conf/domain_conf.h, src/conf/domain_conf.c, src/libvirt_private.syms
	  Add virDomainDefClearPCIAddresses() method for wiping out auto assigned
	  PCI addresses
	* src/qemu/qemu_driver.c: Clear PCI addresses at VM shutdown

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Auto-add disk controllers based on defined disks
	Existing applications using libvirt are not aware of the disk
	controller concept. Thus, after parsing the <disk> definitions
	in the XML, it is neccessary to create <controller> elements
	to satisfy all requested disks, as per their defined drive
	addresses

	* src/conf/domain_conf.c, src/conf/domain_conf.h,
	  src/libvirt_private.syms: Add virDomainDefAddDiskControllers()
	  method for populating disk controllers, and call it after
	  parsing disk definitions.
	* src/qemu/qemu_conf.c: Call virDomainDefAddDiskControllers()
	  when doing ARGV -> XML conversion
	* tests/qemuxml2argvdata/qemuxml2argv*.xml: Add disk controller
	  data to all data files which don't have it already

	Remove restriction on duplicated sound devices in parser
	It is perfectly acceptable to have multiple sound devices of
	same type in guest configuration. If the underlying hypervisor
	does not like this, it is its job to complain, not the XML
	parser's

	* src/conf/domain_conf.c: Remove hack which deleted duplicated
	  sound device models.
	* tests/xml2sexprdata/xml2sexpr-fv-sound.xml: Remove duplicate
	  models

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Detect PCI addresses at QEMU startup
	Hotunplug of devices requires that we know their PCI address. Even
	hotplug of SCSI drives, required that we know the PCI address of
	the SCSI controller to attach the drive to. We can find this out
	by running 'info pci' and then correlating the vendor/product IDs
	with the devices we booted with.

	Although this approach is somewhat fragile, it is the only viable
	option with QEMU < 0.12, since there is no way for libvirto set
	explicit PCI addresses when creating devices in the first place.
	For QEMU > 0.12, this code will not be used.

	* src/qemu/qemu_driver.c: Assign all dynamic PCI addresses on
	  startup of QEMU VM, matching vendor/product IDs
	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
	  src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h,
	  src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h: Add
	  API for fetching PCI device address mapping

2010-01-18  Daniel P. Berrange  <berrange@redhat.com>

	Properly support SCSI drive hotplug
	The current SCSI hotplug support attaches a brand new SCSI controller
	for every disk. This is broken because the semantics differ from those
	used when starting the VM initially. In the latter case, each SCSI
	controller is filled before a new one is added.

	If the user specifies an high drive index (sdazz) then at initial
	startup, many intermediate SCSI controllers may be added with no
	drives.

	This patch changes SCSI hotplug so that it exactly matches the
	behaviour of initial startup. First the SCSI controller number is
	determined for the drive to be hotplugged. If any controller upto
	and including that controller number is not yet present, it is
	attached. Then finally the drive is attached to the last controller.

	NB, this breaks SCSI hotunplug, because there is no 'drive_del'
	command in current QEMU. Previous SCSI hotunplug was broken in
	any case because it was unplugging the entire controller, not
	just the drive in question.

	A future QEMU will allow proper SCSI hotunplug of a drive.

	This patch is derived from work done by Wolfgang Mauerer on disk
	controllers.

	* src/qemu/qemu_driver.c: Fix SCSI hotplug to add a drive to
	 the correct controller, instead of just attaching a new
	  controller.

	  support for 'drive_add' command

2010-01-18  Wolfgang Mauerer  <wolfgang.mauerer@siemens.com>

	Implement SCSI controller hotplug/unplug for QEMU
	This patch allows for explicit hotplug/unplug of SCSI controllers.
	Ordinarily this is not required, since QEMU/libvirt will attach
	a new SCSI controller whenever one is required. Allowing explicit
	hotplug of controllers though, enables the caller to specify a
	static PCI address, instead of auto-assigning the next available
	PCI slot. Or it will when we have static PCI addressing.

	This patch is derived from Wolfgang Mauerer's disk controller
	patch series.

	Use closest CPU model when decoding from CPUID
	Current implementation of x86Decode() used for CPUID -> model+features
	translation does not always select the closest CPU model. When walking
	through all models from cpu_map.xml the function considers a new
	candidate as a better choice than a previously selected candidate only
	if the new one is a superset of the old one. In case the new candidate
	is closer to host CPU but lacks some feature comparing to the old
	candidate, the function does not choose well.

	This patch changes the algorithm so that the closest model is always
	selected. That is, the model which requires the lowest number of
	additional features to describe host CPU.

	Change detection of xen so that it's actually automatic rather than forced.
	This ensures that ./configure will work fine if xen development packages

	qemu: Use log output for pty assignment if 'info chardev' is unavailable
	qemudFindCharDevicePTYsMonitor reports an error if 'info chardev' didn't
	provide information for a requested device, even if the log output parsing
	had found the pty path for that device. This makes pty assignment fail for
	older QEMU/KVM versions. For example KVM 72 on Debian doesn't support
	'info chardev', so qemuMonitorTextGetPtyPaths cannot parse any useful
	information and the hash for device-id-to-pty-path mapping stays empty.

	Make qemudFindCharDevicePTYsMonitor report an error only if the log output
	parsing and the 'info chardev' parsing failed to provide the pty path.

	Specify bus/unit instead of index for disks with QEMU
	The current code for using -drive simply sets the -drive 'index'
	parameter. QEMU internally converts this to bus/unit depending
	on the type of drive. This does not give us precise control over
	the bus/unit assignment though. This change switches over to make
	libvirt explicitly calculate the bus/unit number.

	In addition bus/unit/index are actually irrelevant for VirtIO
	disks, since each virtio disk is a separate PCI device. No disk
	controller is involved.

	Doing the conversion to bus/unit in libvirt allows us to correctly
	attach SCSI controllers when required.

	* src/qemu/qemu_conf.c: Specify bus/unit instead of index for

	This makes the number of parameters smaller & easier to deal with.
	No functional change

	  src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_text.c,

	Minor fixes for API extension doc
	Update the API Extensions doc to reflect new source directory layout.

2010-01-16  Wolfgang Mauerer  <wolfgang.mauerer@siemens.com>

	Add new domain device: "controller"
	This augments virDomainDevice with a <controller> element
	that is used to represent disk controllers (e.g., scsi
	controllers). The XML format is given by

	  <controller type="scsi" index="<num>">
	     <address type="pci" domain="0xNUM" bus="0xNUM" slot="0xNUM"/>
	  </controller>

	where type denotes the disk interface (scsi, ide,...), index
	is an integer that identifies the controller for association
	with disks, and the <address> element specifies the controller
	address on the PCI bus as described in previous commits
	The address element can be omitted; in this case, an address
	will be assigned automatically.

	Most of the code in this patch is from Wolfgang Mauerer's
	previous disk controller series

	 * docs/schemas/domain.rng: Define syntax for <controller>
	   XML element
	 * src/conf/domain_conf.c, src/conf/domain_conf.h: Define
	   virDomainControllerDef struct, and routines for parsing
	   and formatting XML
	* src/libvirt_private.syms: Add virDomainControllerInsert
	   and virDomainControllerDefFree

2010-01-16  Daniel P. Berrange  <berrange@redhat.com>

	Set default disk controller/bus/unit props
	When parsing the <disk> element specification, if no <address>
	is provided for the disk, then automatically assign one based on
	the <target dev='sdXX'/> device name. This provides for backwards
	compatability with existing applications using libvirt, while also
	allowing new apps to have complete fine grained control.

	* src/conf/domain_conf.h, src/conf/domain_conf.c,
	  src/libvirt_private.syms: Add virDomainDiskDefAssignAddress()
	  for assigning a controller/bus/unit address based on disk target
	* src/qemu/qemu_conf.c: Call virDomainDiskDefAssignAddress() after
	  generating XML from ARGV
	* tests/qemuxml2argvdata/*.xml: Add in drive address information
	  to all XML files

2010-01-16  Daniel P. Berrange  <berrange@redhat.com>

	Add address info to sound, video and watchdog devices
	Add the virDomainDeviceAddress information to the sound, video
	and watchdog devices. This means all of them gain the new XML
	element

	  <address .... />

	This brings them upto par with disk/net/hostdev devices which
	already have address info

	* src/conf/domain_conf.h: Add virDomainDeviceAddress to sound,
	  video & watchdog device struts.
	* src/conf/domain_conf.c: Hook up parsing/formatting for
	  virDomainDeviceAddress in sound, video & watchdog devices
	* docs/schemas/domain.rng: Associate device address info
	  with sound, video & watchdog

2010-01-16  Daniel P. Berrange  <berrange@redhat.com>

	Extend the virDomainDeviceAddress struture to allow disk controller addresses
	Introduce a new structure

	      struct _virDomainDeviceDriveAddress {
	        unsigned int controller;
	        unsigned int bus;
	        unsigned int unit;
	      };

	and plug that into virDomainDeviceAddress and generates XML that
	looks like

	  <address type='drive' controller='1' bus='0' unit='5'/>

	This syntax will be used by the QEMU driver to explicitly control
	how drives are attached to the bus

	* src/conf/domain_conf.h, src/conf/domain_conf.c: Parsing and
	  formatting of drive addresses
	* docs/schemas/domain.rng: Define new address format for drives

2010-01-16  Daniel P. Berrange  <berrange@redhat.com>

	Introduce a standardized data structure for device addresses
	All guest devices now use a common device address structure
	summarized by:

	  enum virDomainDeviceAddressType {
	    VIR_DOMAIN_DEVICE_ADDRESS_TYPE_NONE,
	    VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI,
	  };

	  struct _virDomainDevicePCIAddress {
	    unsigned int domain;
	    unsigned int bus;
	    unsigned int slot;
	    unsigned int function;
	  };

	  struct _virDomainDeviceInfo {
	    int type;
	    union {
	        virDomainDevicePCIAddress pci;
	    } addr;
	  };

	This replaces the anonymous structs in Disk/Net/Hostdev data
	structures. Where available, the address is *always* printed
	in the XML file, instead of being hidden in the internal state
	file.

	  <address type='pci' domain='0x0000' bus='0x1e' slot='0x07' function='0x0'/>

	The structure definition is based on Wolfgang Mauerer's disk
	controller patch series.

	* docs/schemas/domain.rng: Define the <address> syntax and
	  associate it with disk/net/hostdev devices
	* src/conf/domain_conf.h, src/conf/domain_conf.c,
	  src/libvirt_private.syms: APIs for parsing/formatting address
	  information. Also remove the QEMU specific 'pci_addr' attributes
	* src/qemu/qemu_driver.c: Replace use of 'pci_addr' attrs with
	  new standardized format.

	Implement path lookup for USB by vendor:product
	Based off how QEMU does it, look through /sys/bus/usb/devices/* for
	matching vendor:product info, and if found, use info from the surrounding
	files to build the device's /dev/bus/usb path.

	This fixes USB device assignment by vendor:product when running qemu
	as non-root (well, it should, but for some reason I couldn't reproduce
	the failure people are seeing in [1], but it appears to work properly)

	node_device: udev: Fix memory leak
	We are setting the same property two different ways without
	free'ing in between. Just drop the second assignment.

	node_device: udev: Enumerate floppy devices
	There are quite a few differences between how udev exposes legacy
	and USB floppy devs, but this patch takes care of both variants.

2010-01-13  Cole Robinson  <crobinso@redhat.com>

	node_device: udev: Use base 16 for product/vendor
	udev doesn't prefix USB product/vendor info with '0x', so the
	strtol conversions were wrong for the product field (vendor already
	set the correct base). Make the change for PCI product/vendor as
	well to be safe.

	This fixes USB device assignment via virt-manager.

	Fix migration in xend driver
	Upstream xen has changed parameters to the migration operation
	several times over the past 18 months.  Changeset 17553 removed
	the resouce parameter,  Changesets 17709, 17753, and 20326 added
	ssl, node, and change_home_server parameters respectively.

	Fortunately, testing has revealed that xend will fail the
	operation if a parameter is missing but happily honor it if
	unknown parameters are provided.  Thus all currently supported
	parameters can be provided, satisfying current xend but not
	regressing older versions.

	Ensure error handling callback functions are called from safe context
	The virRaiseErrorFull() may invoke the error handler callback
	functions an application has registered. This is not good
	because the connection object may not be available at this
	point, and the caller may be holding locks. This creates a
	problem if the error handler calls back into libvirt.

	The solutuon is to move invocation of the handler into the
	final cleanup code in the public API entry points, where it
	is guarenteed to have safe state.

	* src/libvirt.c: Invoke virDispatchError() in all error paths
	* src/util/virterror.c: Remove virSetConnError/virSetGlobalError,

	qemudWaitForMonitor calls qemudReadLogOutput with qemudFindCharDevicePTYs

	esx: Fix 'vpx' MAC address range and allow arbitrary MAC addresses
	The MAC addresses with 00:50:56 prefix are split into several ranges:

	  00:50:56:00:00:00 - 00:50:56:3f:ff:ff  'static' range (manually assigned)
	  00:50:56:80:00:00 - 00:50:56:bf:ff:ff  'vpx' range (assigned by a VI Client)

	Erroneously the 'vpx' range was assumed to be larger and to occupy the
	remaining addresses of the 00:50:56 prefix that are not part of the 'static'
	range.

	00:50:56 was used as prefix for generated MAC addresses, this is not possible
	anymore, because there are gaps in the allowed ranges. Therefore, change the
	prefix to 00:0c:29 which is the prefix for auto generated MAC addresses anyway.

	Allow arbitrary MAC addresses to be used and set the checkMACAddress VMX option
	to false in case the MAC address doesn't fall into any predefined range.

	* docs/drvesx.html.in: update website accordingly
	* src/esx/esx_driver.c: set the auto generation prefix to 00:0c:29

	esx: Don't warn about an empty URI path

	esx: Also allow virtualHW version 4 for ESX 4.0
	A domain with virtualHW version 4 is allowed on an ESX 4.0 server.
	If a domain is migrated from an ESX 3.5 server to an ESX 4.0 server
	then the virtualHW version stays the same. So a ESX 4.0 server can
	host domains with virtualHW version 4.

	on a 0.6.3 (RHEL-5) machine, the errors are not properly reported.
	This patch from Olivier Fourdan <ofourdan@redhat.com> , slightly
	modified to not change the semantic when the domain os details cannot
	be provided

	Fix undefined reference to 'close_used_without_including_unistd_h'
	Found while trying to cross-compile libvirt on Fedora 12 for Windows.
	gnulib redefines 'close' to 'close_used_without_including_unistd_h'
	in sys/socket.h if winsock2.h is present and unistd.h has not been
	included before sys/socket.h. Reorder some includes to fix this.

	Fix argument type of virProcessInfoSetAffinity dummy function

	Define ATTRIBUTE_SENTINEL for GCC < 4.0 too
	ATTRIBUTE_SENTINEL was defined for GCC >= 4.0 only, resulting in
	compile errors when using GCC < 4.0.

	Fix compilation  with configure --disable-nls

	cpu: Fix memory leaks in x86FeatureLoad and x86ModelLoad
	Also backup and restore the original ctxt->node value in x86FeatureLoad.

	Fix configure check for SASL
	The option --with-sasl defaults to 'check', but an inverted test logic
	lets the SASL check fail with an error instead of disabling SASL.
	Fix the test logic so SASL support gets disabled if SASL is missing and
	--with-sasl is set to check.

	Fix GnuTLS pkg-config check
	The testlogic for $PKG_CONFIG was inverted, checking for an empty string
	before using PKG_CHECK_MODULES. Use -x instead of -z and add an else branch
	to the if checking for $GNUTLS_FOUND = no to add -lgcrypt in case the
	GnuTLS libraries are detected by pkg-config.

	Report an error if no XDR library can be found

	Make Xen VT-d PCI attach/detach work
	The Xen code for making HVM VT-d PCI passthrough attach and detach
	wasn't working properly:

	1)  In xenDaemonAttachDevice(), we were always trying to reconfigure
	a PCI passthrough device, even the first time we added it.  This was
	because the code in virDomainXMLDevID() was not checking xenstore for
	the existence of the device, and always returning 0 (meaning that
	the device already existed).

	2)  In xenDaemonDetachDevice(), we were trying to use "device_destroy"
	to detach a PCI device.  While you would think that is the right
	method to call, it's actually wrong for PCI devices.  In particular,
	in upstream Xen (and soon in RHEL-5 Xen), device_configure is actually
	used to destroy a PCI device.

	To fix the attach
	problem I add a lookup into xenstore to see if the device we are
	trying to attach already exists.  To fix the detach problem I change
	it so that for PCI detach (only), we use device_configure with the
	appropriate sxpr to do the detachment.

	* src/xen/xend_internal.c: don't use device_destroy for PCI devices
	  and fix the other issues.
	* src/xen/xs_internal.c src/xen/xs_internal.h: add
	  xenStoreDomainGetPCIID()

	Fix detection of JSON when restarting libvirtd
	The XML XPath for detecting JSON in the running VM statefile was
	wrong causing all VMs to get JSON mode enabled at libvirtd restart.

	In addition if a VM was running a JSON enabled QEMU once, and then
	altered to point to a non-JSON enabled QEMU later the 'monJSON'
	flag would not get reset to 0.

	Fix reporting of TLS connection errors
	The code for connecting to a server tries each socket in turn

	python: Add python bindings for virDomainMemoryStats
	Enable virDomainMemoryStats in the python API.  dom.memoryStats() will return a
	dictionary containing the supported statistics.  A dictionary is required
	because the meaining of each quantity cannot be inferred from its index in a
	list.

	* python/generator.py: reenable bindings for this entry point
	* python/libvirt-override-api.xml python/libvirt-override.c: the
	  generator can't handle this new function, add the new binding,
	  and the XML description

2009-12-20  Adam Litke  <agl@us.ibm.com>

	Add a new command dommemstats for virDomainMemoryStats
	Define a new command 'dommemstats' to report domain memory statistics.  The
	output format is inspired by 'domblkstat' and 'domifstat' and consists of
	tag/value pairs, one per line.  The command can complete successfully and
	print no output if virDomainMemoryStats is supported by the driver, but not
	the guest operating system.

	Sample output:
	swap_in 0
	swap_out 0
	major_fault 54
	minor_fault 58259
	unused 487680
	available 502472

	All stats referring to a quantity of memory (eg. all above except major and
	minor faults) represent the quantity in KBytes.

	* tools/virsh.c: implements the new command

	Add domainMemoryStats support to remote driver
	Use a dynamically sized xdr_array to pass memory stats on the wire.  This

	Implements domainMemStats in the qemu driver
	Support for memory statistics reporting is accepted for qemu inclusion.
	Statistics are reported via the monitor command 'info balloon' as a comma
	seprated list:

	(qemu) info balloon
	balloon: actual=1024,mem_swapped_in=0,mem_swapped_out=0,major_page_faults=88,minor_page_faults=105535,free_mem=1017065472,total_mem=1045229568

	Libvirt, qemu, and the guest operating system may support a subset of the
	statistics defined by the virtio spec.  Thus, only statistics recognized by
	components will be reported.

	* src/qemu/qemu_driver.c src/qemu/qemu_monitor_text.[ch]: implement the

	esx: Add more links to external documentation

	esx: Destroy virtual machine on a vCenter if available
	If a virtual machine is destroyed on a ESX server then immediately
	undefining this virtual machine on a vCenter may fail, because the
	vCenter has not been informed about the status change yet. Therefore,
	destroy a virtual machine on a vCenter if available, so the vCenter
	is up-to-date when the virtual machine should be undefined.

	esx: Undefine virtual machine on a vCenter if available
	Undefining a virtual machine on an ESX server leaves a orphan on the
	vCenter behind. So undefine a virtual machine on a vCenter if available
	to fix this problem.

	esx: Don't warn about '/' paths

	esx: Use occurrence enum to specify expected result of a SOAP call
	Also move XPath expression composition into esxVI_Context_Execute().

	esx: Fix occurence typo

	esx: Extend documentation about 'vcenter' and add some about 'auto_answer'

	esx: Extend vCenter query parameter
	If an ESX host is managed by a vCenter, it knows the IP address of the
	vCenter. Setting the vCenter query parameter to * allows to connect to the
	vCenter known to an ESX host without the need to specify its IP address
	or hostname explicitly.

	esx: Removed unused inttypes.h include

	esx: Replace libxml1 'xmlChildrenNode' with libxml2 'children'

2009-12-19  Matthias Bolte  <matthias.bolte@googlemail.com>

	esx: Improve domain lookup by UUID
	esxDomainLookupByUUID() and esxDomainIsActive() lookup a domain by asking
	ESX for all known domains and searching manually for the one with the
	matching UUID. This is inefficient. The VI API allows to lookup by UUID
	directly: FindByUuid().

	* src/esx/esx_driver.c: change esxDomainLookupByUUID() and esxDomainIsActive()
	  to use esxVI_LookupVirtualMachineByUuid(), also reorder some functions to
	  keep them in sync with the driver struct

	Fix compilation with gcrypt < 1.4.2
	Commit 33a198c1f6a4a1bc7f34d50a31032e03bec10fee increased the gcrypt
	version requirement to 1.4.2 because the GCRY_THREAD_OPTION_VERSION
	define was added in this version.

	The configure script doesn't check for the gcrypt version. To support
	gcrypt versions < 1.4.2 change the virTLSThreadImpl initialization
	to use GCRY_THREAD_OPTION_VERSION only if it's defined.

2009-12-19  Diego Elio Pettenò  <flameeyes@gmail.com>

	Don't mix LDFLAGS and LIBS in the configure script
	* configure.in: If you pass libraries in the LDFLAGS variable, and then
	  try AC_CHECK_FUNCS to find whether a function is present or not,
	  it'll fail badly when using the --as-needed linker flag. Instead,
	  pass the libraries through the LIBS library, so that they are passed
	  after the conftest.c source file and the tests are done properly.

	Don't make it possible to define HAVE_HAL but not enable it in automake
	* configure.in: With the previous logic, if libhal_get_all_devices
	  function was not found, HAVE_HAL would be defined for the preprocessor
	  but it wouldn't be enabled in automake conditionals, causing the final
	  link to fail with missing references to HAL entries.

2009-12-18  Jiri Denemark  <jdenemar@redhat.com>

	Adds CPU selection infrastructure
	Each driver supporting CPU selection must fill in host CPU capabilities.
	When filling them, drivers for hypervisors running on the same node as
	libvirtd can use cpuNodeData() to obtain raw CPU data. Other drivers,
	such as VMware, need to implement their own way of getting such data.
	Raw data can be decoded into virCPUDefPtr using cpuDecode() function.

	When implementing virConnectCompareCPU(), a hypervisor driver can just
	call cpuCompareXML() function with host CPU capabilities.

	For each guest for which a driver supports selecting CPU models, it must
	set the appropriate feature in guest's capabilities:

	    virCapabilitiesAddGuestFeature(guest, "cpuselection", 1, 0)

	Actions needed when a domain is being created depend on whether the
	hypervisor understands raw CPU data (currently CPUID for i686, x86_64
	architectures) or symbolic names has to be used.

	Typical use by hypervisors which prefer CPUID (such as VMware and Xen):

	- convert guest CPU configuration from domain's XML into a set of raw
	  data structures each representing one of the feature policies:

	    cpuEncode(conn, architecture, guest_cpu_config,
	              &forced_data, &required_data, &optional_data,
	              &disabled_data, &forbidden_data)

	- create a mask or whatever the hypervisor expects to see and pass it
	  to the hypervisor

	Typical use by hypervisors with symbolic model names (such as QEMU):

	- get raw CPU data for a computed guest CPU:

	    cpuGuestData(conn, host_cpu, guest_cpu_config, &data)

	- decode raw data into virCPUDefPtr with a possible restriction on
	  allowed model names:

	    cpuDecode(conn, guest, data, n_allowed_models, allowed_models)

	- pass guest->model and guest->features to the hypervisor

	XML schema for CPU flags
	XML schema for CPU flags

	Firstly, CPU topology and model with optional features have to be
	advertised in host capabilities:

	    <host>
	        <cpu>
	            <arch>ARCHITECTURE</arch>
	            <features>
	                <!-- old-style features are here -->
	            </features>
	            <model>NAME</model>
	            <topology sockets="S" cores="C" threads="T"/>
	            <feature name="NAME"/>
	        </cpu>
	        ...
	    </host>

	Secondly, drivers which support detailed CPU specification have to
	advertise
	it in guest capabilities:

	    <guest>
	    ...
	    <features>
	            <cpuselection/>
	        </features>
	    </guest>

	And finally, CPU may be configured in domain XML configuration:

	<domain>
	    ...
	    <cpu match="MATCH">
	        <model>NAME</model>
	        <topology sockets="S" cores="C" threads="T"/>
	        <feature policy="POLICY" name="NAME"/>
	    </cpu>
	</domain>

	Where MATCH can be one of:
	    - 'minimum'     specified CPU is the minimum requested CPU
	    - 'exact'       disable all additional features provided by host CPU
	    - 'strict'      fail if host CPU doesn't exactly match

	POLICY can be one of:
	    - 'force'       turn on the feature, even if host doesn't have it
	    - 'require'     fail if host doesn't have the feature
	    - 'optional'    match host
	    - 'disable'     turn off the feature, even if host has it
	    - 'forbid'      fail if host has the feature

	'force' and 'disable' policies turn on/off the feature regardless of its
	availability on host. 'force' is unlikely to be used but its there for
	completeness since Xen and VMWare allow it.

	'require' and 'forbid' policies prevent a guest from being started on a host
	which doesn't/does have the feature. 'forbid' is for cases where you disable
	the feature but a guest may still try to access it anyway and you don't want
	it to succeed.

	'optional' policy sets the feature according to its availability on host.
	When a guest is booted on a host that has the feature and then migrated to
	another host, the policy changes to 'require' as we can't take the feature
	away from a running guest.

	Default policy for features provided by host CPU but not specified in domain
	configuration is set using match attribute of cpu tag. If 'minimum' match is
	requested, additional features will be treated as if they were specified
	with 'optional' policy. 'exact' match implies 'disable' policy and 'strict'
	match stands for 'forbid' policy.

	Initialize gcrypt threading
	GNUTLS uses gcrypt for its crypto functions. gcrypt requires
	that the app/library initializes threading before using it.
	We don't want to force apps using libvirt to know about
	gcrypt, so we make virInitialize init threading on their
	behalf. This location also ensures libvirtd has initialized
	it correctly. This initialization is required even if libvirt
	itself were only using one thread, since another non-libvirt
	library (eg GTK-VNC) could also be using gcrypt from another
	thread

	on some types of file systems, it is invalid, so do not rely on it.
	Use gnulib's areadlink module instead.
	* bootstrap (modules): Add areadlink.
	* src/util/util.c: Include "areadlink.h".
	Let areadlink perform the readlink and malloc.
	* configure.in (AC_CHECK_FUNCS): Remove readlink.  No need,
	since it's presence is guaranteed by gnulib.

	build: update gnulib submodule to latest

	xm_internal.c: remove misleading dead code
	* src/xen/xm_internal.c (xenXMConfigGetULong): Remove useless and
	misleading test (always false) for val->str == NULL before code that
	always dereferences val->str.  "val" comes from virConfGetValue, and
	at that point, val->str is guaranteed to be non-NULL.
	(xenXMConfigGetBool): Likewise.
	* src/util/conf.c (virConfSetValue): Ensure that vir->str is never NULL,
	not even if someone tries to set such a value via virConfSetValue.

	libvirt.c: don't let a NULL "cpumaps" argument provoke a NULL-deref

	qemu migration: avoid NULL-deref given an invalid input
	* src/qemu/qemu_driver.c (doNonTunnelMigrate): Don't let a
	NULL "uri_out" provoke a NULL-dereference in doNativeMigrate:
	supply omitted goto-after-qemudReportError.

	qemu_driver.c: don't unlink(NULL) on OOM error path
	* src/qemu/qemu_driver.c (qemudDomainMigratePrepareTunnel): Upon an
	out of memory error, we would end up with unixfile==NULL and attempt
	to unlink(NULL).  Skip the unlink when it's NULL.

	remote_driver.c: also zero out ->saslDecodedOffset member
	* src/remote/remote_driver.c (remoteIOReadMessage): ...rather than
	zeroing out priv->saslDecodedLength twice.

	qemu_driver.c: avoid double free on error path
	* src/qemu/qemu_driver.c (qemudDomainMigrateFinish2): Set
	"event" to NULL after qemuDomainEventQueue frees it, so a
	subsequent free (after endjob label) upon qemuMonitorStartCPUs
	failure does not cause a double free.

	libvirtd: avoid a NULL dereference on error path
	* daemon/libvirtd.c (qemudDispatchServer): Since "client" may be

	Fix install location for Python bindings
	Commit 66137344feb488ea87b0d92f3c03844d9a7a7786 changed the Python detection
	mechanism in configure to use AM_PATH_PYTHON. This results in a changed
	install location for the Python bindings, at least on Fedora 12 64bit systems.

	Before this commit libvirt.py and libvirtmod.so were installed to

	  /usr/lib64/python2.6/site-packages

	After this commit they are installed to

	  /usr/lib/python2.6/site-packages

	Mixed Python packages (containing *.py and *.so files) should be installed to
	the pyexecdir directory detected by AM_PATH_PYTHON.

	This restores the install location from before the AM_PATH_PYTHON commit.

	* configure.in: remove unnecessary pythondir export
	* python/Makefile.am: switch from pythondir to pyexecdir

	Get QEMU pty paths from the monitor
	This change makes the QEMU driver get pty paths from the output of the
	monitor 'info chardev' command. This output is structured, and contains
	both the name of the device and the path on the same line. This is
	considerably more reliable than parsing the startup log output, which
	requires the parsing code to know which order QEMU will print pty
	information in.

	Note that we still need to parse the log output as the monitor itself
	may be on a pty. This should be rare, however, and the new code will
	replace all pty paths parsed by the log output method once the monitor
	is available.

	* src/qemu/qemu_monitor.(c|h) src/qemu_monitor_text.(c|h): Implement
	  qemuMonitorGetPtyPaths().

	retrieve paused/running state at migration start
	This patch fixes the bug where paused/running state is not

	for example the machine was always started on the destination

	In order to do so, just read the state and if it is appropriate and

	remove iptablesReloadRules() and related code
	We don't use this method of reloading rules anymore, so we can just

	remove all traces of lokkit support
	Long ago we tried to use Fedora's lokkit utility in order to register
	our iptables rules so that 'service iptables restart' would
	automatically load our rules.

	There was one fatal flaw - if the user had configured iptables without
	lokkit, then we would clobber that configuration by running lokkit.

	We quickly disabled lokkit support, but never removed it. Let's do
	that now.

	The 'my virtual network stops working when I restart iptables' still
	remains. For all the background on this saga, see:

	  https://bugzilla.redhat.com/227011

	* src/util/iptables.c: remove lokkit support

	* configure.in: remove --enable-lokkit

	* libvirt.spec.in: remove the dirs used only for saving rules for lokkit

	* src/Makefile.am: ditto

	* src/libvirt_private.syms, src/network/bridge_driver.c,

2009-12-10  Mark McLoughlin  <markmc@redhat.com>

	reload iptables rules on libvirtd restart
	This is the expected behaviour, I think - reloading libvirtd should
	be a subset of restarting it.

	Note, we reload the rules after we've determined which networks
	are active (because we only add the rules for active networks)
	and before we start autostart networks (to avoid re-adding the
	rules).

	* src/network/bridge_driver.c: reload iptables rules on startup

2009-12-10  Mark McLoughlin  <markmc@redhat.com>

	reload iptables rules simply by re-adding them
	Currently, when we add iptables rules, we keep them on a list so that
	we can easily reload them on e.g. 'service libvirtd reload'.

	However, we don't save this list to disk, so if libvirtd is restarted
	we lose the ability to reload the rules.

	The fix is simple - just re-add the damn things on reload.

	Note, we delete the rules before re-adding them, just like the current
	behaviour of iptRulesReload().

	* src/network/bridge_driver.c: re-add the iptables rules on reload.

	Make QEMU text monitor parsing more robust
	The QEMU 0.10.0 release (and possibly other 0.10.x) has a bug where
	it sometimes/often forgets to display the initial monitor greeting
	line, soley printing a (qemu).  This in turn confuses the text
	console parsing because it has a '(qemu)' it is not expecting. The
	confusion results in a negative malloc. Bad things follow.

	This re-writes the text console handling to be more robust. The key
	idea is that it should only look for a (qemu), once it has seen the
	original command echo'd back. This ensures it'll skip the bogus stray
	(qemu) with broken QEMUs.

	* src/qemu/qemu_monitor.c: Add some (disabled) debug code

	Fix virDomainObj ref handling in QEMU driver
	Since the monitor I/O is processed out of band from the main
	thread(s) invoking monitor  commands, the virDomainObj may be
	deleted by the I/O thread. The qemuDomainObjBeginJob takes an
	extra reference to protect against final deletion, but this
	reference is released by the corresponding EndJob call. THus
	after the EndJob call it may not be valid to reference the
	virDomainObj any more. To allow callers to detect this, the
	EndJob call is changed to return the remaining reference count.

	* src/conf/domain_conf.c: Make virDomainObjUnref return the
	  remaining reference count
	* src/qemu/qemu_driver.c: Avoid referencing virDomainObjPtr
	  after qemuDomainObjEndJob if it has been deleted.

	Use AM_PATH_PYTHON and python-config to detect Python configuration
	Using AM_PATH_PYTHON solves the site-packages directory problem. At least
	in Ubuntu with Python 2.6 and later site-packages is renamed to dist-packages
	and site-packages is not part of sys.path anymore. So installing the libvirt
	Python bindings to site-packages renders them unusable, because they can be
	imported from there without manually including site-packages into sys.path.

	AM_PATH_PYTHON detects the correct site-packages/dist-packages directory.

	python-config --includes gives the correct include path for the Python header
	files. The old probing code stays there as fallback mechanism.

	Fix crash when deleting monitor while a command is in progress
	If QEMU shuts down while we're in the middle of processing a

	the qemuMonitorPtr object, and hold an extra reference whenever
	executing a command.

	vbox: Use virIndexToDiskName() in vboxGenerateMediumName()

2009-12-05  Jiri Denemark  <jdenemar@redhat.com>

	Tests for interface type/model configuration
	add a set of tests for Xen interface type and model configurations

2009-12-04  Jiri Denemark  <jdenemar@redhat.com>

	Support for interface model='netfront'
	Xen HVM guests with PV drivers end up with two network interfaces for
	each configured interface. One of them being emulated by qemu and the
	other one paravirtual. As this might not be desirable, the attached
	patch provides a way for users to specify that only paravirtual network
	interface should be presented to the guest.

	The configuration was inspired by qemu/kvm driver, for which users can
	specify model='virtio' to use paravirtual network interface.

	The patch adds support for model='netfront' which results in
	type=netfront instead of type=ioemu (or nothing for newer xen versions)
	in guests native configuration. Xen's qemu ignores interfaces with
	type != ioemu and only paravirtual network device will be seen in the
	guest.

	Four possible configuration scenarios follow:

	- no model specified in domain's XML
	    - libvirt will behave like before this change; it will set
	      type=ioemu for HVM guests on xen host which is not newer than
	      XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU
	    - covered by existing tests

	- PV guest, any model
	    - no functional change, model is passed as is (and ignored by the
	      hypervisor)
	    - covered by existing tests (e.g., *-net-e1000.*)
	- HVM guest, model=netfront
	    - type is set to "netfront", model is not specified
	    - covered by new *-net-netfront.* tests

	- HVM guest, model != netfront
	    - type is set to "ioemu", model is passed as is
	    - covered by new *-net-ioemu.* tests

	The fourth scenario feels like a regression for xen newer than
	XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified
	in their guest's configuration won't see a paravirtual interface in
	their guests any more. On the other hand, the reason for specifying a
	model is most likely the fact that they want to use such model which
	implies emulated interface. Users of older xen won't be affected at all
	as their xen provides paravirtual interface regardless of the type used.

	- src/xen/xend_internal.c: add netfront support for the xend backend
	- src/xen/xm_internal.c: add netfront support for the XM serialization too

	Add virIndexToDiskName and fix mapping gap
	esxVMX_IndexToDiskName handles indices up to 701. This limit comes
	from a mapping gap in virDiskNameToIndex:

	  sdzy -> 700
	  sdzz -> 701
	  sdaaa -> 728
	  sdaab -> 729

	This line in virDiskNameToIndex causes this gap:

	  idx = (idx + i) * 26;

	Fixing it by altering this line to:

	  idx = (idx + (i < 1 ? 0 : 1)) * 26;

	Also add a new version of virIndexToDiskName that handles the inverse
	mapping for arbitrary indices.

	Fix event test timer checks on kernels with HZ=100
	On kernels with HZ=100, the resolution of sleeps in poll() is
	quite bad. Doing a precise check on the expiry time vs the
	current time will thus often thing the timer has not expired
	even though we're within 10ms of the expected expiry time. This
	then causes another pointless sleep in poll() for <10ms. Timers
	do not need to have such precise expiration, so we treat a timer
	as expired if it is within 20ms of the expected expiry time. This
	also fixes the eventtest.c test suite on kernels with HZ=100

	Don't return fatal error in HAL driver init if HAL isn't running
	The HAL driver returns a fatal error code in the case where HAL

	AppArmor handling of accesses to readonly files
	Fixes https://launchpad.net/bugs/453335

	* src/security/virt-aa-helper.c: suppress confusing and misleading
	  apparmor denied message when kvm/qemu tries to open a libvirt specified

	Remove capng_lock() call when spawning LXC container init process
	The capng_lock() call sets the SECURE_NO_SETUID_FIXUP and SECURE_NOROOT

	Allow timeouts waiting for QEMU job lock
	Some monitor commands may take a very long time to complete. It is
	not desirable to block other incoming API calls forever. With this
	change, if an existing API call is holding the job lock, additional
	API calls will not wait forever. They will time out after a short
	period of time, allowing application to retry later.

	* include/libvirt/virterror.h, src/util/virterror.c: Add new
	  VIR_ERR_OPERATION_TIMEOUT error code
	* src/qemu/qemu_driver.c: Change to a timed condition variable
	  wait for acquiring the monitor job lock

2009-11-10  Daniel P. Berrange  <berrange@redhat.com>

	Release driver and domain lock when running monitor commands
	QEMU monitor commands may sleep for a prolonged period of time.
	If the virDomainObjPtr or qemu driver lock is held this will
	needlessly block execution of many other API calls. it also
	prevents asynchronous monitor events from being dispatched
	while a monitor command is executing, because deadlock will
	ensure.

	To resolve this, it is neccessary to release all locks while
	executing a monitor command. This change introduces a flag
	indicating that a monitor job is active, and a condition
	variable to synchronize access to this flag. This ensures that
	only a single thread can be making a state change or executing
	a monitor command at a time, while still allowing other API
	calls to be completed without blocking

	* src/qemu/qemu_driver.c: Release driver and domain lock when
	  running monitor commands. Re-add locking to disk passphrase
	  callback
	* src/qemu/THREADS.txt: Document threading rules

2009-11-10  Daniel P. Berrange  <berrange@redhat.com>

	Fully asynchronous monitor I/O processing
	Change the QEMU monitor file handle watch to poll for both
	read & write events, as well as EOF. All I/O to/from the
	QEMU monitor FD is now done in the event callback thread.

	When the QEMU driver needs to send a command, it puts the
	data to be sent into a qemuMonitorMessagePtr object instance,
	queues it for dispatch, and then goes to sleep on a condition
	variable. The event thread sends all the data, and then waits
	for the reply to arrive, putting the response / error data
	back into the qemuMonitorMessagePtr and notifying the condition
	variable.

	There is a temporary hack in the disk passphrase callback to
	avoid acquiring the domain lock.  This avoids a deadlock in
	the command processing, since the domain lock is still held
	when running monitor commands. The next commit will remove
	the locking when running commands & thus allow re-introduction
	of locking the disk passphrase callback

	* src/qemu/qemu_driver.c: Temporarily don't acquire lock in
	  disk passphrase callback. To be reverted in next commit
	* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Remove

	Add reference counting on virDomainObjPtr objects
	Add reference counting on the virDomainObjPtr objects. With the
	forthcoming asynchronous QEMU monitor, it will be neccessary to
	release the lock on virDomainObjPtr while waiting for a monitor
	command response. It is neccessary to ensure one thread can't
	delete a virDomainObjPtr while another is waiting. By introducing
	reference counting threads can make sure objects they are using
	are not accidentally deleted while unlocked.

	Make use of private data structure for monitor state
	Introduce a new qemuDomainObjPrivate object which is used to store
	the private QEMU specific data associated with each virDomainObjPtr
	instance. This contains a single member, an instance of the new
	qemuMonitorPtr object which encapsulates the QEMU monitor state.
	The internals of the latter are private to the qemu_monitor* files,

	Move code for low level QEMU monitor interaction into separate file
	The qemu_driver.c code should not contain any code that interacts
	with the QEMU monitor at a low level. A previous commit moved all
	the command invocations out. This change moves out the code which
	actually opens the monitor device.

	* src/qemu/qemu_driver.c: Remove qemudOpenMonitor & methods called
	  from it.
	* src/Makefile.am: Add qemu_monitor.{c,h}
	* src/qemu/qemu_monitor.h: Add qemuMonitorOpen()

	Allow character devices to have different target types
	A character device's target (it's interface in the guest) had only a
	single property: port. This patch is in preparation for adding targets
	which require other properties.
	Since this changes the conf type for character devices this affects
	a number of drivers:

	* src/conf/domain_conf.[ch] src/esx/esx_vmx.c src/qemu/qemu_conf.c
	  src/qemu/qemu_driver.c src/uml/uml_conf.c src/uml/uml_driver.c
	  src/vbox/vbox_tmpl.c src/xen/xend_internal.c src/xen/xm_internal.c:
	  target properties are moved into a union in virDomainChrDef, and a
	  targetType field is added to identify which union member should be
	  used. All current code which touches a virDomainChrDef is updated both
	  to use the new union field, and to populate targetType if necessary.

	LXC allow container to have ethN interfaces
	Current implementation of lxc driver creates vethN named
	interface(s) in the host and passes as it is to a container.
	The reason why it doesn't use ethN is due to the limitation
	that one namespace cannot have multiple iterfaces that have
	an identical name so that we give up creating ethN named
	interface in the host for the container.

	However, we should be able to allow the container to have
	ethN by changing the name after clone(CLONE_NEWNET).

	* src/lxc/lxc_container.c src/lxc/veth.c src/lxc/veth.h: do the clone
	  and then renames interfaces eth0 ... ethN to keep the interface names

	  in the two functions if <dhcp> is not provided

	Make monitor type (miimon/arpmon) optional in bond xml
	* src/conf/interface_conf.c: lack of one of these in the live xml output

2009-11-04  Laine Stump  <laine@laine.org>

	Support reporting live interface IP/netmask
	This patch adds the flag VIR_INTERFACE_XML_INACTIVE to
	virInterfaceGetXMLDesc's flags. When it is*not* set (the default), the
	live interface info will be returned in the XML (in particular, the IP
	address(es) and netmask(s) will be retrieved by querying the interface
	directly, rather than  reporting what's in the config file). The
	backend of this is in netcf's ncf_if_xml_state() function.

	* configure.in libvirt.spec.in: requires netcf >= 0.1.3
	* include/libvirt/libvirt.h.in: adds flag VIR_INTERFACE_XML_INACTIVE
	* src/conf/interface_conf.c src/interface/netcf_driver.c src/libvirt.c:

2009-11-04  Laine Stump  <laine@laine.org>

	Make startmode optional in toplevel interface definition
	The minimal XML returned from ncf_if_xml_state() doesn't contain this

	through the parse/format step.

	* src/conf/interface_conf.[ch]: add a new virInterfaceStartMode value
	  and modify loading/saving accordingly

2009-11-04  Daniel P. Berrange  <berrange@redhat.com>

	Move libvirtd event loop into background thread
	The virStateInitialize() call for starting up stateful drivers
	may require that the event loop is running already. This it is
	neccessary to start the event loop before this call. At the
	same time, network clients must not be processed until afte
	virStateInitialize has completed.

	The qemudListenUnix() and remoteListenTCP() methods must
	therefore not register file handle watches, merely open the
	network sockets & listen() on them. This means clients can
	connected and are queued, pending completion of initialization

	The qemudRunLoop() method is moved into a background thread
	that is started early to allow access to the event loop during
	driver initialization. The main process thread leader pretty
	much does nothing once the daemon is running, merely waits
	for the event loop thread to quit

	* daemon/libvirtd.c, daemon/libvirtd.h: Move event loop into
	  a background thread
	* daemon/THREADING.txt: Rewrite docs to better reflect reality

	Allow NULL mac address in virGetInterface
	There are places where an interface will not have a mac address, and netcf

	in the virInterface object as an empty string.

	Fix return value in virStateInitialize impl for LXC
	The LXC driver was mistakenly returning -1 for lxcStartup()
	in scenarios that are not an error. This caused the libvirtd

	The user assumes to communicate with the server over a secure transport
	but isn't.

	This patch disables automatical redirection following. The driver reports

	Don't let parent of daemon exit until basic initialization is done
	The daemonizing code lets the parent exit almost immediately. This
	means that it may think it has successfully started even when
	important failures occur like not being able to acquire the PID
	file. It also means network sockets are not yet open.

	To address this when daemonizing the parent passes an open pipe
	file descriptor to the child. The child does its basic initialization
	and then writes a status code to the pipe indicating either success,
	or failure. This ensures that when daemonizing, the parent does not
	exit until the pidfile is acquired & basic network sockets are open.

	Initialization of the libvirt drivers is still done asynchronously
	since this may take a very long time.

	Fix duplicating logging of errors in libvirtd
	The libvirt default error handling callback will print all errors
	to stderr. The libvirtd default logging callback will do the same.
	Set a no-op error handling callback in libvirtd to prevent this
	duplication

	* daemon/libvirtd.c: Register a no-op error handling function

	Annotate many methods with ATTRIBUTE_RETURN_CHECK & fix problems
	Nearly all of the methods in src/util/util.h have error codes that

	Add ATTRIBUTE_RETURN_CHECK to ensure compile time validation of
	this

	* daemon/libvirtd.c: Add explicit check on return value of virAsprintf
	* src/conf/domain_conf.c: Add missing check on virParseMacAddr return
	  value status & report error

	Allow for a driver specific private data blob in virDomainObjPtr
	The virDomainObjPtr object stores state about a running domain.
	This object is shared across all drivers so it is not appropriate
	to include driver specific state here. This patch adds the ability
	to request a blob of private data per domain object instance. The
	driver must provide a allocator & deallocator for this purpose

	THis patch abuses the virCapabilitiesPtr structure for storing the
	allocator/deallocator callbacks, since it is already being abused
	for other internal things relating to parsing. This should be moved
	out into a separate object at some point.

	* src/conf/capabilities.h: Add privateDataAllocFunc and
	  privateDataFreeFunc fields
	* src/conf/domain_conf.c: Invoke the driver allocators / deallocators
	  when creating/freeing virDomainObjPtr instances.
	* src/conf/domain_conf.h: Pass virCapsPtr into virDomainAssignDef
	  to allow access to the driver specific allocator function
	* src/lxc/lxc_driver.c, src/opennebula/one_driver.c,
	  src/openvz/openvz_driver.c, src/qemu/qemu_driver.c,
	  src/test/test_driver.c, src/uml/uml_driver.c: Update for
	  change in virDomainAssignDef contract

	Don't use private struct member names of in6_addr
	__in6_u.__u6_addr16 is the private name for this struct member,

	  Richard Jones

2009-10-29  Daniel P. Berrange  <berrange@redhat.com>

	Convert virDomainObjListPtr to use a hash of domain objects
	The current virDomainObjListPtr object stores domain objects in
	an array. This means that to find a particular objects requires
	O(n) time, and more critically acquiring O(n) mutex locks.

	The new impl replaces the array with a virHashTable, keyed off
	UUID. Finding a object based on UUID is now O(1) time, and only
	requires a single mutex lock. Finding by name/id is unchanged
	in complexity.

	In changing this, all code which iterates over the array had
	to be updated to use a hash table iterator function callback.
	Several of the functions which were identically duplicating
	across all drivers were pulled into domain_conf.c

	* src/conf/domain_conf.h, src/conf/domain_conf.c: Change
	  virDomainObjListPtr to use virHashTable. Add a initializer
	  method virDomainObjListInit, and rename virDomainObjListFree
	  to virDomainObjListDeinit, since its not actually freeing
	  the container, only its contents. Also add some convenient
	  methods virDomainObjListGetInactiveNames,
	  virDomainObjListGetActiveIDs and virDomainObjListNumOfDomains
	  which can be used to implement the correspondingly named
	  public API entry points in drivers
	* src/libvirt_private.syms: Export new methods from domain_conf.h
	* src/lxc/lxc_driver.c, src/opennebula/one_driver.c,
	  src/openvz/openvz_conf.c, src/openvz/openvz_driver.c,
	  src/qemu/qemu_driver.c, src/test/test_driver.c,
	  src/uml/uml_driver.c, src/vbox/vbox_tmpl.c: Update all code
	  to deal with hash tables instead of arrays for domains

	libvirt-devel should only require libvirt-client
	There's a long known issue where if you install libvirt in a guest,
	the default virtual network will conflict with the default virtual
	network in the host.

	That's one of the reasons we have the libvirt-client RPM - it allows
	you to install the client library without having the host side
	installed.

	Rich Jones points out that if you install libvirt-devel in a guest,
	then you get libvirtd installed and the network conflict:

	  https://bugzilla.redhat.com/531200

	libvirt-devel should only require libvirt-client - e.g. nothing in
	the devel package pertains to anything in the libvirt RPM. The Fedora
	packaging guidelines say:

	  https://fedoraproject.org/wiki/Packaging/Guidelines#Devel_Packages

	  Devel packages must require the base package using a fully versioned
	  dependency ...

	But for all intents and purposes, libvirt-client is our base RPM.

	* libvirt.spec.in: make libvirt-devel require libvirt-client

	virterror: Add a missing 'break' for VIR_ERR_INVALID_SECRET

	qemu: migrate: Don't require manual URI to specify a port
	The xen driver will generate a migration port if only a hostname is passed
	in the optional migrate URI, so let's do the same in qemu.

	Fix p2p migration without a passed uri.

	qemu: Fix an error message in GetVcpus

	test: Support virStorageFindPoolSources
	The results are hardcoded into the test driver, no option to read from a
	testfile is implemented at this time.

	storage: Add ParseSourceString function for use with FindPoolSources.
	This will simplify adding FindPoolSources support to more pool backends in
	the future (as well as the test driver).

	storage: Break out function to add pool source to a SourceList.
	Similar in theory to *AssignDef type functions, this duplicate functionality
	will be used by an future FindPoolSources implementations.

	storage: Break out pool source parsing to a separate function.
	We need to parse a source XML block for FindPoolSources, so this is a step
	in sharing the parsing. The new storage pool XML 2 XML tests cover this area
	pretty well to ensure we aren't causing regressions.

2009-10-28  Paolo Bonzini  <pbonzini@redhat.com>

	Add support for an external TFTP boot server
	This patch adds an optional attribute to the <bootp> tag, that
	allows to specify a TFTP server address other than the address of
	the DHCP server itself.

	This can be used to forward the BOOTP settings of the host down to the
	guest.  This is something that configurations such as Xen's default
	network achieve naturally, but must be done manually for NAT.

	* docs/formatnetwork.html.in: Document new attribute.
	* docs/schemas/network.rng: Add it to schema.
	* src/conf/network_conf.h: Add it to struct.
	* src/conf/network_conf.c: Add it to parser and pretty printer.
	* src/network/bridge_driver.c: Put it in the dnsmasq command line.
	* tests/networkxml2xmlin/netboot-proxy-network.xml
	  tests/networkxml2xmlout/netboot-proxy-network.xml

2009-10-26  Chris Lalancette  <clalance@redhat.com>

	Add a new syntax-check rule for gethostname.
	We should always be using virGetHostname in place of
	gethostname; thus add in a new syntax-check rule to make
	sure no new uses creep in.

	Various syntax-check fixes.
	Make a pass over the syntax-check files, tightening up regex's,
	un-ignoring certain files, and cleaning things up.

	Tighten up nonreentrant syntax-check.
	We can slightly tighten up the regex's used to detect the use of
	nonreentrant functions.  We can also check src/util/virterror.c
	by modifying a comment; I think it's worth it to get the additional
	coverage.

	Replace a gethostname by virGetHostname in libvirtd.c

	Replace two strcmp() by STREQ() in qemu_driver.c

	Replace gethostname by virGetHostname in xend_internal.c

	Remove a completely bogus reference increment in the Xen driver.
	xenUnifiedDomainEventRegister() calls out to
	virDomainEventCallbackListAdd(), which increments the reference
	count on the connection.  That is fine, but then
	xenUnifiedDomainEventRegister() increments the usage count again,
	leading to a usage count leak.  Remove the increment in the xen
	register, and the UnrefConnect in the xen unregister.

	Add a default log_level to qemudSetLogging to remove a build warning.
	(original patch from Charles Duffy)

	Better error message when libvirtd fails to start.

2009-10-22  Matthias Bolte  <matthias.bolte@googlemail.com>

	Fix potential false-positive OOM error reporting.
	If no matching device was found (cap == NULL) then no strdup() call
	was made and *wwnn and *wwpn are untouched. Checking them for NULL
	in this situation may result in reporting an false-positive OOM error
	because *wwnn and *wwpn may be initialized to NULL by the caller.

	Only check *wwnn and *wwpn for NULL if a matching device was found
	(cap != NULL) and thus strdup() was called.

	* src/conf/node_device_conf.c: only report an OOM error if there
	  really is one

	Consolidate virXPathNodeSet()
	virXPathNodeSet() could return -1 when doing an evaluation failure
	due to xmlXPathEval() from libxml2 behaviour.

	  XPath type is of the wrong type (meaning the query passed didn't
	  evaluate to a node set and code must be fixed)

2009-10-12  Mark McLoughlin  <markmc@redhat.com>

	Fix schema to allow missing machine type
	The domain/os/type element may have an arch specified without having
	a machine variant specified. In fact, this is what python-virtinst
	does when defining a guest.

	* docs/schemas/domain.rng: allow missing machine type

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Rewrite example domain events programm for python
	The existing python demo for domain events does not fully
	implement the event loop contract. This makes the code useless
	for real world applications. This change re-writes the demo so
	that it has a full event loop implementation which is suitable
	for application usage & better demonstrates integration

	* examples/domain-events/events-python/event-test.py: Rewrite
	  to include a real world usable event loop implementation

	  auto-generated files from source control
	* Makefile.am: Add rule for generating NEWS file
	* docs/Makefile.am: Remove rule for generating NEWS file

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Support a new peer-to-peer migration mode & public API
	Introduces several new public API options for migration

	 - VIR_MIGRATE_PEER2PEER: With this flag the client only
	   invokes the virDomainMigratePerform method, expecting
	   the source host driver to do whatever is required to
	   complete the entire migration process.
	 - VIR_MIGRATE_TUNNELLED: With this flag the actual data
	   for migration will be tunnelled over the libvirtd RPC
	   channel. This requires that VIR_MIGRATE_PEER2PEER is
	   also set.
	 - virDomainMigrateToURI: This is variant of the existing
	   virDomainMigrate method which does not require any
	   virConnectPtr for the destination host. Given suitable
	   driver support, this allows for all the same modes as
	   virDomainMigrate()

	The URI for VIR_MIGRATE_PEER2PEER must be a valid libvirt
	URI. For non-p2p migration a hypervisor specific migration
	URI is used.

	virDomainMigrateToURI without a PEER2PEER flag is only
	support for Xen currently, and it involves XenD talking
	directly to XenD, no libvirtd involved at all.

	* include/libvirt/libvirt.h.in: Add VIR_MIGRATE_PEER2PEER
	  flag for migration
	* src/libvirt_internal.h: Add feature flags for peer to
	  peer migration (VIR_FEATURE_MIGRATE_P2P) and direct
	  migration (VIR_MIGRATE_PEER2PEER mode)
	* src/libvirt.c: Implement support for VIR_MIGRATE_PEER2PEER
	  and virDomainMigrateToURI APIs.
	* src/xen/xen_driver.c: Advertise support for DIRECT migration
	* src/xen/xend_internal.c: Add TODO item for p2p migration
	* src/libvirt_public.syms: Export virDomainMigrateToURI
	  method
	* src/qemu/qemu_driver.c: Add support for PEER2PEER and
	  migration, and adapt TUNNELLED migration.
	* tools/virsh.c: Add --p2p and --direct args and use the
	  new virDomainMigrateToURI method where possible.

	Re-arrange doTunnelMigrate to simplify cleanup code
	Re-arrange the doTunnelMigrate method putting all non-QEMU local
	state setup steps first. This maximises chances of success before
	then starting destination QEMU for receiving incoming migration.
	Altogether this can reduce the number of goto cleanup labels to
	something more managable.

	* qemu/qemu_driver.c: Re-order steps in doTunnelMigrate

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Separate out code for sending tunnelled data
	Simplify the doTunnelMigrate code by pulling out the code for
	sending all tunnelled data into separate helper

	* qemu/qemu_driver.c: introduce doTunnelSendAll() method

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Pull connection handling code out of doTunnelMigrate
	Simplify the doTunnelMigrate() method by pulling out the code
	which opens/closes the virConnectPtr  object into a parent
	method

	* qemu/qemu_driver.c: Add doPeer2PeerMigrate which then calls
	  doTunnelMigrate with dconn & dom_xml

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Fix stream abort upon I/O failure during migration
	virStreamAbort is needed when the caller wishes to terminate
	the stream early, not when virStreamSend fails.

	* qemu/qemu_driver.c: Fix calling of virStreamAbort during
	  tunnelled migration

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Refactor native QEMU migration code
	The code for tunnelled migration was added in a dedicated method,
	but the native migration code is still inline in the top level
	qemudDomainMigratePerform() API. Move the native code out into
	a dedicated method too to make things more maintainable.

	* src/qemu/qemu_driver.c: Pull code for performing a native
	  QEMU migration out into separate method

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Don't force dconn to be NULL in virDomainMigrate
	The code for tunnelled migration wierdly required the app to pass
	a  NULL 'dconn' parameter, only to have to use virConnectOpen
	itself shortly thereafter to get a 'dconn' object. Remove this
	bogus check & require the app to always pas 'dconn' as before

	* src/libvirt.c: Require 'dconn' for virDomainMigrate calls again
	  and remove call to virConnectOpen

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Remove unneccessary uri_in parameter from virMigratePrepareTunnel
	Since virMigratePrepareTunnel() is used for migration over the
	native libvirt connection, there is never any need to pass the
	target URI to this method.

	* daemon/remote.c, src/driver.h, src/libvirt.c, src/libvirt_internal.h,
	  src/qemu/qemu_driver.c, src/remote/remote_driver.c,
	  src/remote/remote_protocol.c, src/remote/remote_protocol.h,

2009-10-09  Daniel P. Berrange  <berrange@redhat.com>

	Move the VIR_DRV_FEATURE* constants
	Move the VIR_DRV_FEATURE* constants into libvirt_internal.h
	since these flags are indicating whether  APIs in the
	libvirt_internal.h file are supported by a driver

	* src/driver.h: Remove VIR_DRV_FEATURE* constants
	* src/libvirt_internal.h: Add VIR_DRV_FEATURE* constants, using

	LXC add augeas support for config file
	* src/lxc/libvirtd_lxc.aug src/lxc/test_libvirtd_lxc.aug: augeas schemas
	  for lxc.conf
	* src/Makefile.am libvirt.spec.in: glue the new augeas files in

2009-10-08  Amy Griffis  <amy.griffis@hp.com>

	LXC add driver config file lxc.conf
	* src/lxc/lxc.conf: new configuration file, there is currently one
	  tunable "log_with_libvirtd" that controls whether an lxc controller will
	  log only to the container log file, or whether it will honor libvirtd's
	  log output configuration. This provides a way to have libvirtd and its
	  children log to a single file.  The default is to log to the container
	  log file.
	* src/Makefile.am libvirt.spec.in: add the new file
	* src/lxc/lxc_conf.[ch] src/lxc/lxc_driver.c: read the new log value
	  from the configuration file and pass the log informations when
	  starting up a container.

	LXC do not truncate container log files on restart
	* src/lxc/lxc_driver.c: use O_APPEND instead of O_TRUNC when opening
	  the log file on lxcVmStart()

	LXC initialize logging configuration
	* src/lxc/lxc_driver.c src/lxc/lxc_controller.c: before launching the
	  lxc controller, have the lxc driver query the log settings and setup
	  envp[]. This provides the advantage of honoring the actual log
	  configuration instead of only what had been set in the environment.
	  The lxc controller now simply has to call virLogSetFromEnv().

	Add debug for envp[] in virExecWithHook()
	* src/util/util.c: output some debug if caller of virExecWithHook have
	  set envp[]

2009-10-08  Amy Griffis  <amy.griffis@hp.com>

	Add accessors for logging filters and outputs
	When configuring logging settings, keep more information about the
	output destination. Add accessors to retrieve the filter and output
	settings in the original string form; this to be used to set up
	environment for a child process that also logs.

	* src/util/logging.[ch]: add virLogGetFilters and virLogGetOutputs
	  accessors and modify the internals (including virLogDefineOutput())
	  to save the data needed for the accessors

2009-10-08  Amy Griffis  <amy.griffis@hp.com>

	Add virFileAbsPath() utility
	* src/util/util.[ch]: Add virFileAbsPath() function to ensure an

	LXC implement memory control APIs
	The patch implements the missing memory control APIs for lxc, i.e.,
	domainGetMaxMemory, domainSetMaxMemory, domainSetMemory, and improves
	domainGetInfo to return proper amount of used memory via cgroup.

	* src/libvirt_private.syms: Export virCgroupGetMemoryUsage
	  and add missing virCgroupSetMemory
	* src/lxc/lxc_driver.c: Implement missing memory functions
	* src/util/cgroup.c, src/util/cgroup.h: Add the function

2009-10-07  Jamie Strandboge  <jamie@canonical.com>

	Add a domain argument to SVirt *RestoreImageLabel
	When James Morris originally submitted his sVirt patches (as seen in
	libvirt 0.6.1), he did not require on disk labelling for
	virSecurityDomainRestoreImageLabel. A later commit[2] changed this
	behavior to assume on disk labelling, which halts implementations for
	path-based MAC systems such as AppArmor and TOMOYO where
	vm->def->seclabel is required to obtain the label.

	* src/security/security_driver.h src/qemu/qemu_driver.c
	  src/security/security_selinux.c: adds the 'virDomainObjPtr vm'
	  argument back to *RestoreImageLabel

2009-10-07  Chris Lalancette  <clalance@redhat.com>

	Fix up "make check"
	While running make check, I noticed that it was actually using
	the virsh binary from my system, in /usr/bin/virsh, and not the
	one that was just compiled.  This is actually caused by a bug
	in Makefile.am, where we didn't update the PATH to include tools.

	While here, I also updated all of the scripts to properly define
	the srcdir, abs_top_srcdir, and abs_top_builddir environment
	variables.  This is required if you want to be able to run the
	tests standalone (i.e. ./test instead of from make check).  I've
	tested this on both RHEL-5 and Fedora-10 machines, and make check
	works on both, as does running the individual tests by hand.

	Create /var/log/libvirt/{lxc,uml} dirs
	Otherwise logrotate barfs:

	  error: found error in /var/log/libvirt/qemu/*.log /var/log/libvirt/uml/*.log /var/log/libvirt/lxc/*.log , skipping

	* qemud/Makefile.am: always create /var/log/libvirt/{lxc,uml} when
	  installing the logrotate conf; not ideal, but easier than making
	  the logrotate conf depend on which drivers are enabled

2009-10-06  Daniel P. Berrange  <berrange@redhat.com>

	Fix rebuilding of devhelp files
	The devhelp/ directory files depend on libvirt-api.xml being
	uptodate, but automake always processes SUBDIRS before the
	current directory. So devhelp would be built and then the
	libvirt-api.xml re-build, invalidating the devhelp data again.

	To fix this all the rules for devhelp are moved directly
	into the docs/Makefile.am allowing make to see the global
	dependancy chain and thus build things in the correct order

	* docs/Makefile.am: Add rules for devhelp rebuild
	* docs/devhelp/Makefile.am: Remove devhelp rebuild
	* configure.in: Remove docs/devhelp/Makefile.am

	python: Fix generated virInterface method names
	A mistake in the generator was causing virInterface methods to be generated

	Does anyone care if we are breaking API compat? My guess is that no one is
	using the python interface bindings yet.

2009-10-06  Cole Robinson  <crobinso@redhat.com>

	python: Use a pure python implementation of 'vir*GetConnect'
	The API docs explictly warn that we shouldn't use the C vir*GetConnect calls
	in bindings: doing so can close the internal connection pointer and cause

	python: Don't generate bindings for vir*Ref
	They are only for use in implementing the bindings, so shouldn't be
	exposed to regular API users.

	Change signature of remoteSendStreamData() to fix compile warning
	The actual type of size_t is architecture dependent. Because the len
	parameter is used as unsigned int in remoteSendStreamData(), change its
	type to unsigned int.

	  remoteSendStreamData()

	* src/security/security_selinux.c: re-label backing store files in
	  SELinuxSetSecurityImageLabel()

2009-09-30  Mark McLoughlin  <markmc@redhat.com>

	  the caller does not need to open the file

2009-09-30  Mark McLoughlin  <markmc@redhat.com>

	Move virStorageGetMetadataFromFD() to libvirt_util
	Finally, we get to the point of all this.

	Move virStorageGetMetadataFromFD() to virStorageFileGetMetadataFromFD()
	and move to src/util/storage_file.[ch]

	Introduce a metadata structure and make virStorageGetMetadataFromFD()
	fill it in.

	* src/util/storage_file.h: add virStorageFileMetadata

	* src/backend/storage_backend_fs.c: virStorageGetMetadataFromFD() now
	  fills in the virStorageFileMetadata structure

2009-09-30  Mark McLoughlin  <markmc@redhat.com>

	Split virStorageGetMetadataFromFD() from virStorageBackendProbeTarget()
	Prepare the code probing a file's format and associated metadata for
	moving into libvirt_util.

	* src/storage/storage_backend_fs.c: re-factor the format and metadata
	  probing code in preparation for moving it

2009-09-30  Mark McLoughlin  <markmc@redhat.com>

	Move file format enum to libvirt_util

2009-09-30  Matthias Bolte  <matthias.bolte@googlemail.com>

	Fix memory leaks in libvirtd's message processing
	Commit 47cab734995fa9521b1df05d37e9978eedd8d3a2 changed the way how
	qemud_client_message objects were reused. Before this commit
	remoteDispatchClientRequest() reused the received message for normal responses
	and to report non-fatal errors. If a fatal error occurred qemudWorker() frees
	the message. After this commit non-fatal errors are reported by
	remoteSerializeReplyError() using a new qemud_client_message object and the
	original message leaks.

	To fix this leak the original message has to be freed if
	remoteSerializeReplyError() succeeds. If remoteSerializeReplyError()
	fails the original message is freed in qemudWorker().

	* daemon/dispatch.c: free qemud_client_message objects that will not be reused
	  and would leak otherwise, also free the allocated qemud_client_message object
	  in remoteSerializeError() if an error occurs

2009-09-30  Daniel P. Berrange  <berrange@redhat.com>

2009-09-29  Daniel P. Berrange  <berrange@redhat.com>

	Allow control over QEMU audio backend
	When using VNC for graphics + keyboard + mouse, we shouldn't
	then use the host OS for audio. Audio should go back over
	VNC.

	When using SDL for graphics, we should use the host OS for
	audio since that's where the display is. We need to allow
	certain QEMU env variables to be passed through to guest
	too to allow choice of QEMU audio backend.

	* qemud/libvirtd.sysconf: Mention QEMU/SDL audio env vars
	* src/qemu_conf.c: Passthrough QEMU/SDL audio env for SDL display,
	  disable host audio for VNC display

	  operation so that it accepts a client object too.
	* daemon/qemud.c: Refactor code for free'ing message objects
	  which have been fully transmitted into separate method.
	  Release all active streams when client shuts down. Change
	  filter function to be responsible for queueing the message

2009-09-29  Daniel P. Berrange  <berrange@redhat.com>

	Maintain value of ctxt->node in virInterfaceDefParseDhcp
	* src/conf/interface_conf.c: This was causing subsequent calls to
	  virXPathxxx() to fail, since ctxt->node was left pointing at the
	  dhcp node, rather than the protocol node.

2009-09-29  Daniel Veillard  <veillard@redhat.com>

	Fix some XPath relative node resets
	* src/util/xml.c: The virXPath... function take extra care to preserve
	  the XPath context node (ctxt->node) but in the case of virXPathString
	  and virXPathBoolean they forgot to do this on the error path. This
	  patch fixes this and move all ctxt->node = relnode instuctions just
	  after the xmlXPathEval() to make sure this doesn't happen if this code
	  is modified.

	Fix API doc extractor to stop munging comment formatting
	The python method help docs are copied across from the C
	funtion comments, but in the process all line breaks and
	indentation was being lost. This made the resulting text
	and code examples completely unreadable. Both the API
	doc extractor and the python generator were destroying
	whitespace & this fixes them to preserve it exactly.

	* docs/apibuild.py: Preserve all whitespace when extracting
	  function comments. Print function comment inside a <![CDATA[
	  section to fully preserve all whitespace. Look for the
	  word 'returns' to describe return values, instead of 'return'
	  to avoid getting confused with code examples including the
	  C 'return' statement.
	* python/generator.py: Preserve all whitespace when printing
	  function help docs
	* src/libvirt.c: Change any return parameter indicated by
	  'return' to be 'returns', to avoid confusing the API extractor
	* docs/libvirt-api.xml: Re-build for fixed descriptions

	network: add 'bootp' and 'tftp' config
	Currently, libvirtd will start a dnsmasq process for the virtual
	network, but (aside from killing the dnsmasq process and replacing it),
	there's no way to define tftp boot options.

	This change introduces the appropriate tags to the dhcp configuration:

	 <network>
	   <name>default</name>
	   <bridge name="virbr%d" />
	   <forward/>
	   <ip address="192.168.122.1" netmask="255.255.255.0">
	     <tftp root="/var/lib/tftproot" />
	     <dhcp>
	       <range start="192.168.122.2" end="192.168.122.254" />
	       <bootp file="pxeboot.img"/>
	     </dhcp>
	   </ip>
	 </network>

	When the attributes are present, these are passed to the
	arguments to dnsmasq:

	 dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img
	               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^
	                      from <tftp />                     from <bootp />

	At present, only local tftp servers are supported (ie, dnsmasq runs as
	the tftp server), but we could improve this in future by adding a
	server= attribute.

	Introduce virStrncpy.
	Add the virStrncpy function, which takes a dst string, source string,
	the number of bytes to copy and the number of bytes available in the
	dest string.  If the source string is too large to fit into the
	destination string, including the \0 byte, then no data is copied and
	the function returns NULL.  Otherwise, this function copies n bytes
	from source into dst, including the \0, and returns a pointer to the
	dst string.  This function is intended to replace all unsafe uses
	of strncpy in the code base, since strncpy does *not* guarantee that
	the buffer terminates with a \0.

	Fix xen driver refcounting.
	The commit cb51aa48a777ddae6997faa9f28350cb62655ffd "Fix up connection
	reference counting." changed the driver closing and virConnectPtr
	unref-logic in virConnectClose().

	Before this commit virConnectClose() closed all drivers of the given
	virConnectPtr and virUnrefConnect()'ed it afterwards. After this
	commit the driver-closing is done in virUnrefConnect() if and only if
	the ref-count of the virConnectPtr dropped to zero.

	This change in execution order leads to a virConnectPtr leak, at least
	for connections to Xen.

	The relevant call sequences:

	virConnectOpen() -> xenUnifiedOpen() ...

	... xenInotifyOpen() -> virConnectRef(conn)

	... xenStoreOpen() -> xenStoreAddWatch() -> conn->refs++

	virConnectClose() -> xenUnifiedClose() ...

	... xenInotifyClose() -> virUnrefConnect(conn)

	... xenStoreClose() -> xenStoreRemoveWatch() -> virUnrefConnect(conn)

	Before the commit this additional virConnectRef/virUnrefConnect calls
	where no problem, because virConnectClose() closed the drivers
	explicitly and the additional refs added by the Xen subdrivers were
	removed properly. After the commit this additional refs result in a
	virConnectPtr leak (including a leak of the hypercall file handle;
	that's how I noticed this problem), because now the drivers are only
	close if and only if the ref-count drops to zero, but this cannot
	happen anymore, because the additional refs from the Xen subdrivers
	would only be removed if the drivers get closed, but that doesn't
	happen because the ref-count cannot drop to zero.

	The fix for this problem is simple: remove the
	virConnectRef/virUnrefConnect calls from the Xen subdrivers (see
	attached patch). Maybe someone could explain why the Xen Inotify and
	Xen Store driver do this extra ref-counting, but none of the other Xen
	subdrivers. It seems unnecessary to me and can be removed without
	problems.

	Refactor libvirt.spec to allow client-only builds
	Some architectures in certain RHEL versions do not include any
	hypervisors. Update the specfile to allow those to easily build
	a remote client only version of libvirt. ie no libvirtd related
	bits at all.

	* qemud/Makefile.am: Always instal SASL config since its needed
	  by client too
	* libvirt.spec.in: Re-factor specfile conditionals to allow entire
	  server side build to be disabled easily, eg a remote client only
	  build. Make RHEL-5 do client only build for s390/ppc. Make RHEL-6
	  do a client only build for all non-x86_64 archs. Enable LXC on
	  RHEL-6. Enable all Fedora >= 6 features on RHEL-6 too. Add some
	  more conditionals around dnsmasq/iptables/hal Requires tags.
	  Add missing e2fsprogs-devel BR for RHEL-5 as workaround for broken
	  parted. Fix the device mapper BR for RHEL-5. Add conditional rules
	  for ESX build. Add conditional rules for SELinux + HAL builds.
	  Fix a mistaken %{with_qemu} to be %{with_network} when setting
	  up default network XML

	Integrate with QEMU monitor to provide encryption passphrase when
	starting a guest using encrypted qcow volumes

	* src/qemu_driver.c (findDomainDiskEncryption,
	  findVolumeQcowPassphrase,
	  qemudMonitorSendVolumePassphrase, qemudMonitorSendCont): Send a volume
	  passphrase if qemu asks for it.

2009-09-11  Miloslav Trmač  <mitr@redhat.com>

	Provide missing passphrase when creating a volume.
	If the <encryption format='qcow'> element does not specify a secret
	during volume creation, generate a suitable secret and add it to the
	<encryption> tag.  The caller can view the updated <encryption> tag
	using virStorageVolGetXMLDesc().

	Similarly, when <encryption format='default'/> is specified while
	creating a qcow or qcow2-formatted volume, change the format to "qcow"
	and generate a secret as described above.

	* src/storage_encryption_conf.h (VIR_STORAGE_QCOW_PASSPHRASE_SIZE,
	  virStorageGenerateQcowPasphrase),
	  src/storage_encryption_conf.c (virStorageGenerateQcowPasphrase),
	  src/libvirt_private.syms: Add virStorageGenerateQcowPasphrase().

	* docs/virsh.pod, virsh.1: Update documentation.

2009-09-11  Miloslav Trmač  <mitr@redhat.com>

	Local file implementation of secret driver API
	This implementation stores the secrets in an unencrypted text file,
	for simplicity in implementation and debugging.

	(Symmetric encryption, e.g. using gpgme, will not be difficult to add.
	Because the TLS private key used by libvirtd is stored unencrypted,
	encrypting the secrets file does not currently provide much additional
	security.)

	* include/libvirt/virterror.h, src/virterror.c (VIR_ERR_NO_SECRET): New
	  error number.
	* po/POTFILES.in, src/Makefile.am: Add secret_driver.

	Add an internal <secret> XML handling API
	Add a <secret> XML handling API, separate from the local driver, to
	avoid manually generating XML in other parts of libvirt.

	* src/secret_conf.c, src/secret_conf.h: New files.
	* po/POTFILES.in, src/Makefile.am: Add secret_conf.

2009-09-10  Miloslav Trmač  <mitr@redhat.com>

	Mask out flags used internally for virSecretGetValue
	Add a VIR_SECRET_GET_VALUE_INTERNAL_CALL flag value, replacing the
	originally separate libvirt_internal_call parameter.  The flag is used
	to differentiate external virSecretGetValue() calls from internal calls
	by libvirt drivers that need to use the secret even if it is private.

	* src/libvirt_internal.h Remove VIR_DOMAIN_XML_FLAGS_MASK
	* src/driver.h Add VIR_SECRET_GET_VALUE_FLAGS_MASK constant and
	  VIR_SECRET_GET_VALUE_INTERNAL_CALL. Re-add the
	  VIR_DOMAIN_XML_FLAGS_MASK constant
	* src/libvirt.c (virSecretGetValue): Don't allow the user to specify
	  internal flags.

2009-09-10  Daniel P. Berrange  <berrange@redhat.com>

2009-09-10  Miloslav Trmač  <mitr@redhat.com>

	Consolidate "cont" into qemudMonitorSendCont()
	The interface allows qemudMonitorSendCont() to report errors that are
	not overridden by its callers.

	Also fix a potential infinite loop in qemuDomainCoreDump() if sending
	cont repeatedly fails.

	* src/qemu_driver.c (qemudMonitorSendCont): New function.
	  (qemudAutostartConfigs): Reset error before each call to
	  qemudStartVMDaemon().
	  (qemudInitCpus, qemudDomainResume, qemudDomainCoreDump,
	  qemudDomainRestore, qemudDomainMigratePerform,

	Fix misc thread locking bugs / bogus warnings
	Fix all thread locking bugs reported by object-locking test
	case.

	NB, some of the driver locking is getting too coarse. Driver
	mutexes really need to be turned into RW locks instead to
	significantly increase concurrency.

	* src/lxc_driver.c: Fix useof driver when unlocked in the methods
	  lxcDomainGetInfo, lxcSetSchedulerParameters, and
	  lxcGetSchedulerParameters
	* src/opennebula/one_driver.c: Fix missing unlock in oneDomainUndefine.

	  warnings.
	* tests/object-locking.ml: Add oneDriverLock, oneDriverUnlock
	  and one_driver_t methods/types to allow lock checking on the
	   OpenNebula drivers

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Test that domain-specific qemu machine types are used correctly
	* tests/testutilsqemu.c: add a machine types list for /usr/bin/kvm
	  which doesn't have any aliases, while the guest has aliases

	* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases2.*,
	  tests/qemuxml2argvtest.c: add a test using /usr/bin/kvm and make
	  sure that 'pc' machine type doesn't get canonicalized using the
	  aliases in the guest machine type list

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Simplify and fix qemudCanonicalizeMachine()
	The algorithm is quite simple:

	  If the emulator matches a guest's domain:
	    if domain has machine type info:
	      check the domain's machine type info
	    else
	      check the guest's default machine type info
	  else if the emulator matches the guest's default emulator:
	     check the guest's default machine type info

	The previous implementation was incorrectly falling back to the default
	machine type info if the domain's machine type info didn't have an
	alias.

	* src/qemu_driver.c: simplify and fix qemudCanonicalizeMachine()

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Probe machine types from kvm binary too
	Currently we only probe the main qemu binary for machine types, but we
	should also probe the kvm binary.

	* src/qemu_conf.c: probe kvm binary machines in qemudCapsInitGuest()

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Look up machine types from all domains in qemudGetOldMachines()
	Rather than just looking at the default domain info, look at all
	domains

	* src/qemu_conf.c: look at all domains in qemudGetOldMachines()

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Split up qemudGetOldMachines()
	We need to look at all the domain infos in guest capabilities, not
	just the defaults.

	In order to allow that, split out a qemudGetOldMachinesFromInfo()
	from qemudGetOldMachines(). We'll make more use of it in the next
	patch.

	* src/qemu_conf.c: split out qemudGetOldMachinesFromInfo() from
	  qemudGetOldMachines()

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Re-factor qemu test machine allocation code
	* test/testutilsqemu.c: split out code to testQemuAllocMachines()

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Canonicalize the qemu machine type in qemuxml2argvtest
	This doesn't have any affect on the current tests because we don't have
	any machine aliases in the current test data.

	* src/qemu_conf.h, src/qemu_driver.c: expose qemudCanonicalizeMachine()
	  for the tests

	* tests/qemuxml2argvtest.c: canonicalize the machine type

2009-09-10  Mark McLoughlin  <markmc@redhat.com>

	Add esx and tcp migration uri transports to capabilities schema
	* docs/schemas/capabilities.rng: include esx and tcp uri_transport

2009-09-10  Chris Lalancette  <clalance@redhat.com>

	Fix regression from "Avoid polling on FDs with no events"
	After the mentioned patch was applied, I noticed that
	shutting down a kvm guest from inside (i.e. poweroff) caused
	the guest to shutdown, but not removed from the list of
	active guests.  DanB pointed out that the problem is that
	the virEventAddHandle() call in the qemu driver was asking
	to watch for 0 events, not HANGUP | ERROR as it should.  Add
	these events so that shutdown works again.

2009-09-10  Jim Meyering  <meyering@redhat.com>

	qemu_driver.c: factor out more duplication

	advantages distinct from xz. This has been addressed in the mailing list post
	archived at http://permalink.gmane.org/gmane.comp.emulators.libvirt/16487, and
	support for lzop is re-added here.

	* libvirt.spec.in: add dependancy on lzop

	  to implement the compression options

2009-09-09  Maximilian Wilhelm  <max@rfc2324.org>

	Check for libssh2 >= 1.0 for phy driver
	* configure.in: phyp driver uses libssh2_session_block_directions()
	  which is only available in libssh2 >= 1.0, so check for this symbol
	  too when configuring

2009-09-09  Jim Meyering  <meyering@redhat.com>

	xm_internal.c: remove four useless comparisons after strchr
	* src/xm_internal.c (xenXMDomainConfigParse): After t=strchr...
	don't test *t; it's known.  This was *not* detected by clang,

	VBox fix minor bugs in display and added OOM checks
	* src/vbox/vbox_tmpl.c: minor bug in selecting the graphics type. if the
	  graphics type was desktop it was assumed that display is set for it,

	use "goto cleanup" rather than returning immediately.

	qemu_conf.c: add a comment suggesting why we leave a dead-store
	* src/qemu_conf.c (qemuBuildHostNetStr): Do not remove the type_sep=','

2009-09-04  Daniel P. Berrange  <berrange@redhat.com>

	Avoid polling on FDs with no events enabled
	If a file descriptor with events=0 was added to the libvirtd
	event loop, it would still be added to the poll() fds' array.
	While it wouldn't see any POLLIN/OUT events, it'd still get
	triggered for HANGUP/ERROR events which was not in compliance
	with the libvirt events API contract.

	* qemud/event.c: Don't poll on FDs with events=0
	* tests/eventtest.c: Add test case to validate fix to event.c

2009-09-04  Jim Meyering  <meyering@redhat.com>

2009-09-04  Jim Meyering  <meyering@redhat.com>

	python: let libvirt_virConnectDomainEventCallback indicate success
	* python/libvir.c (libvirt_virConnectDomainEventCallback): Return 0
	when successful, rather than always returning -1.
	clang flagged this function for its dead-store of "ret=0".
	Once "ret" was set to 0, it was never used, and
	the function would always return -1.

	mdns.c: remove dead initialization
	* qemud/mdns.c (libvirtd_mdns_client_callback): Remove dead
	initialization.

	node_device_conf.c: remove dead initialization
	* src/node_device_conf.c (virNodeDeviceDefFormat): Remove dead
	initialization.

	openvz_conf.c: don't use undefined local, "net"
	* src/openvz_conf.c (openvzReadNetworkConf): Initialize "net".
	Otherwise, upon openvzRead... failure, we would "goto error;"
	where an uninitialized "net" could be dereferenced.

	test.c: don't use undefined local, "def"
	* src/test.c (testOpenVolumesForPool): Upon early virAsprintf or
	virXPathNodeSet failure, "goto error" would take us to
	virStorageVolDefFree(def), but with "def" not defined.
	Initialize it to NULL.

	uml_conf.c: don't return an uninitialized pointer
	* src/uml_conf.c (umlBuildCommandLineChr): Initialize "ret".

	storage_backend.c: assure clang that inputvol can't be NULL
	* src/storage_backend.c: Include "internal.h".
	(virStorageBackendCopyToFD): Mark inputvol parameter as "nonnull".
	Remove test for non-NULL inputvol.  Both callers ensure it's non-NULL.

	libvir.c: avoid NULL dereference in virStoragePoolSetAutostart
	* src/libvirt.c (virStoragePoolSetAutostart): Return -1 if the pool
	argument is invalid, rather than "goto error" where we could dereference
	that possibly-NULL "pool".
	(virConnectFindStoragePoolSources): Likewise.
	(virConnectNumOfDomains): Likewise.
	Daniel P. Berrange spotted that the two latter functions
	needed the same treatment.

	remote_internal.c: appease clang
	* src/remote_internal.c (remoteNetworkOpen): Mark "conn" parameter
	as non-NULL.  Remove now-unnecessary "conn == NULL" test.
	(remoteDevMonOpen): Likewise.
	(remoteSecretOpen): Likewise.
	(remoteStorageOpen): Likewise.
	(remoteInterfaceOpen): Likewise.

	infra: define ATTRIBUTE_NONNULL to mark non-NULL parameters
	* src/internal.h (ATTRIBUTE_NONNULL): Define.

	lxc: don't unlink(NULL) in main
	* src/lxc_controller.c (main): Unlink sockpath only if it's non-NULL.

	lxc: avoid NULL dereference upon getmntent failure
	* src/lxc_container.c (lxcContainerUnmountOldFS): Don't pass
	a NULL pointer to qsort.

	storage_conf.c: avoid overflow upon use of "z" or "Z" (zebi) suffix
	* src/storage_conf.c (virStorageSize): Don't try to compute 1024^7,
	since it's too large for a 64-bit type.

	storage_backend_fs: avoid NULL dereference on opendir failure
	* src/storage_backend_fs.c (virStorageBackendFileSystemRefresh):
	Don't call closedir on a NULL pointer.

	  the structure.

2009-09-02  Chris Lalancette  <clalance@redhat.com>

	Fix bugs in virDomainMigrate v2 code.
	Paolo Bonzini points out that in my refactoring of the code for
	virDomainMigrate(), I added a check for the return value from
	virDomainMigratePerform().  The problem is that we don't want to
	exit if we fail, we actually want to go on and do
	virDomainMigrateFinish2() with a non-0 return code to clean things
	up.  Remove the check.

	While reproducing this issue, I also noticed that we wouldn't
	always properly propagate an error message.  In particular, I
	found that if you blocked off the migration ports (with iptables)
	and then tried the migration, it would actually fail but we would
	get no failure output from Qemu.  Therefore, we would think we
	succeeded, and leave a huge mess behind us.  Execute the monitor
	command "info migrate", and look for a failure string in there
	as well.

2009-09-02  Matthias Bolte  <matthias.bolte@googlemail.com>

	VMware ESX: Don't warn on some query parameter
	* src/esx/esx_util.c: esxUtil_ParseQuery() warns if a known query
	  parameter should be ignored due to the corresponding char/int pointer
	  being NULL, instead of silently ignoring it. Fix the control flow.

	VMware ESX: Allow ethernet address type 'vpx'
	* src/esx/esx_vmx.c: add an extra type of addressType beside 'static'
	  and 'generated', 'vpx' indicates that the MAC address was generated
	  by a vCenter.

2009-09-02  Daniel P. Berrange  <berrange@redhat.com>

	Don't blindly reorder disk drives
	Calling qsort() on the disks array causes disk to be
	unneccessarily re-ordered, potentially breaking the
	ability to boot if the boot disk gets moved later in
	the list. The new algorithm will insert a new disk as
	far to the end of the list as possible, while being
	ordered correctly wrt other disks on the same bus.

	* src/domain_conf.c, src/domain_conf.h: Remove disk sorting
	  routines. Add API to insert a disk into existing list at
	  the optimal position, without resorting disks
	* src/libvirt_private.syms: Export virDomainDiskInsert
	* src/xend_internal.c, src/xm_internal.c: Remove calls to
	  qsort, use virDomainDiskInsert instead.
	* src/qemu_driver.c: Remove calls to qsort, use virDoaminDiskInsert
	  instead. Fix reordering bugs when hotunplugging disks and
	  networks. Fix memory leak in disk/net unplug

	  build under proxy
	* src/test.c: Add a dummy no-op secrets driver for test suite

	Only add glusterfs dep for Fedora >= 11
	* libvirt.spec.in: Conditionalize glusterfs requires line for

2009-09-02  Miloslav Trmač  <mitr@redhat.com>

	Don't assume buffered output echoes the command.
	The if ((nlptr...)) implicitly assumes commptr != NULL (and that "buf"
	starts with "cmd").  Make the assumption explicit, it will be broken in
	a future patch.

	* src/qemu_driver.c: Don't assume buffered monitor output echoes the
	  command.

2009-09-02  Miloslav Trmač  <mitr@redhat.com>

	Attach encryption information to virDomainDiskDef.
	The XML allows <encryption format='unencrypted'/>, this implementation
	canonicalizes the internal representation so that "disk->encryption" is
	non-NULL iff encryption information is available.

	A domain with partial encryption information can be defined,

	Note that partial encryption information (e.g. specifying an encryption
	format, but not the key/passphrase) is valid, libvirt will automatically
	choose value for the missing information during volume creation.  The
	user can read the volume XML, and use the unmodified <encryption> tag in

	support lzop save compression for qemu
	Per prior discussion -- this was, indeed, trivial.

	I'm a little disappointed to be breaking the ordering characteristics of
	the enum (as it had been ordered by increasing time requirements and
	decreasing output size), but breaking any save files with the old
	constants in the headers would of course be worse.

	Subject: [PATCH] support lzop save compression for qemu

	One of the larger disincentives towards use of compression for migrated-out save
	files is performance impact. This patch adds support for lzop; CPU time for
	compression is about 5x faster than gzip (the next most performant algorithm)
	and decompression is about 3x faster.

2009-09-01  Chris Lalancette  <clalance@redhat.com>

	OpenVZ: accept NULL as type for GetMaxVCPUs.
	All of the other drivers that support the getMaxVcpus callback
	also accept a NULL value for type.  Make openvz also accept a
	NULL value.

	Remove use of strncpy in qemudExtractMonitorPath.
	qemudExtractMonitorPath() was doing a VIR_ALLOC_N followed by a
	strncpy.  However, this isn't necessary; we can do the same thing
	using strndup, which is much safer.

	Fix up virNodeGetCellsFreeMemory
	The documentation for virNodeGetCellsFreeMemory claims the values
	returned are in kilobytes, but that's actually wrong; the value
	returned is actually in bytes.  Fix up the documentation to be
	correct.

	Matthias correctly points out that escape_specialcharaters() takes a
	length, and since we are now malloc()'ing string in phypOpen instead of
	making it a static array, we can't use sizeof(string) anymore.  Calculate
	the proper strlen and then use that both to allocate the string and also
	pass it to escape_specialcharacters().

	Power Hypervisor: fix potential segfault
	I came across this line in the phypOpen function:

	char string[strlen(conn->uri->path)];

	Here the path part of the given URI is used without checking it for
	NULL, this can cause a segfault as strlen expects a string != NULL.
	Beside that uuid_db and connection_data leak in case of an error.

	In this line

	conn->uri->path = string;

	the original path of the URI leaks. The patch adds a VIR_FREE call
	before setting the new path.

	The attached patch is compile-tested but I don't have a Power

	Maintain a list of active PCI hostdevs and use it in pciResetDevice()

	Simplify PCI hostdev prepare/re-attach using a pciDeviceList type
	The qemuPrepareHostDevices() and qemuDomainReAttachHostDevices()
	functions are clutter with a bunch of calls to pciGetDevice() and
	pciFreeDevice() obscuring the basic logic.

	Add a pciDeviceList type and add a qemuGetPciHostDeviceList() function
	to build a list from a domain definition. Use this in prepare/re-attach
	fto simplify things and eliminate the multiple pciGetDevice calls.

	This is especially useful because in the next patch we need to iterate
	the hostdevs list a third time and we also need a list type for keeping
	track of active devices.

	Fix up connection reference counting.
	Currently the reference counting for connections is busted.  I
	first noticed it while trying to use virConnectRef; it would
	eventually cause a crash in the remote_internal driver, although
	that was really just a victim.  Really, we should only call the
	close callbacks on the methods when the references drop to 0.  To
	accomplish this, move all of the close callbacks into
	virUnrefConnect (since there are lots of internal users of that
	function), and arrange for virConnectClose to call that.

	Compressed save image format for Qemu.
	Implement a compressed save image format for qemu.  While ideally
	we would have the choice between compressed/non-compressed
	available to the libvirt API, unfortunately there is no "flags"
	parameter to the virDomainSave() API.  Therefore, implement this
	as a qemu.conf option.  gzip, bzip2, and lzma are implemented, and
	it should be very easy to implement additional compression
	methods.

	One open question is if/how we should detect the compression
	binaries.  One way to do it is to do compile-time setting of the
	paths (via configure.in), but that doesn't seem like a great thing
	to do.  My preferred solution is not to detect at all;
	when we go to run the commands that need them, if they
	aren't available, or aren't available in one of the standard paths,
	then we'll fail.  That's also the solution implemented in this patch.

	In the future, we'll have a more robust (managed) save/restore API,
	at which time we can expose this functionality properly in the API.

	V2: get rid of redundant dd command and just use >> to append data.
	V3: Add back the missing pieces for the enum and bumping the save version.
	V4: Make the compressed field in the save_header an int.
	    Implement LZMA compression.

	If a PCI device reset causes other devices to be reset, allow it so long

	Allow pciResetDevice() to reset multiple devices

	Extend the pciResetDevice() API so that a 'check' callback can be

	on the bus.

	The virDomainObjPtr parameter is needed so that when the check function
	iterates over the domain list, it can avoid double locking.

	* src/pci.[ch]: add a 'check' callback to pciResetDevice(), re-work
	  pciIterDevices() to pass the check function to the iter functions,

	* src/pci.c: set errors in pciTryPowerManagementReset() and

	Reset and re-attach PCI host devices on guest shutdown

	In the case of managed hostdevs, we should reset and re-attach the
	devices. In the case of unmanaged hostdevs, we should just reset them.

	Note, KVM will already reset assigned devices when the guest shuts
	down using whatever means it can, so we are only doing it to cover the
	cases the kernel can't handle.

	Allow PM reset on multi-function PCI devices
	It turns out that a PCI Power Management reset only affects individual
	functions, and not the whole device.

	The PCI Power Management spec talks about resetting the 'device' rather
	than the 'function', but Intel's Dexuan Cui informs me that it is
	actually a per-function reset.

	Also, Yu Zhao has added pci_pm_reset() to the kernel, and it doesn't
	reject multi-function devices, so it must be true! :-)

	(A side issue is that we could defer the PM reset to the kernel if we
	could detect that the kernel has PM reset support, but barring version
	number checks we don't have a way to detect that support)

	* src/pci.c: remove the pciDeviceContainsOtherFunctions() check from

	Detect KVM's PCI device assignment support
	PCI device assignment is only supported in KVM's fork of qemu, so we
	should really detect its availability and give a nice error if its
	not supported.

	* src/qemu_conf.[ch]: introduce QEMUD_CMD_FLAG_PCIDEVICE indicating
	  that the -pcidevice command line option is available

	* tests/*: update the tests

2009-08-14  Mark McLoughlin  <markmc@redhat.com>

	Add host PCI device hotplug support
	Attaching a host PCI device to a qemu guest is done with a
	straightforward 'pci_add auto host host=XX:XX.X' command.

	Like with NIC and disk hotplug, we need to retain the guest PCI address
	assigned by qemu so that we can use it for hot-unplug.

	Identifying a device for detach is done using the host PCI address.

	Managed mode is handled by detaching/resetting the device before
	attaching it to the guest and re-attaching it after detaching it from
	the guest.

	* src/qemu_driver.c: add qemudDomainAttachHostPciDevice() and
	  qemudDomainDetachHostPciDevice()

	* src/domain_conf.h: add somewhere to store the guest PCI address

	* src/domain_conf.c: handle formatting and parsing the guest PCI
	  address

2009-08-14  Mark McLoughlin  <markmc@redhat.com>

	Re-factor hostdev hotplug
	Re-factor the hostdev hotplug code so that we can easily add PCI
	hostdev hotplug to qemudDomainAttachHostDevice().

	* src/qemu_driver.c: rename qemudDomainAttachHostDevice() to
	  qemudDomainAttachHostUsbDevice(); make qemudDomainAttachHostDevice()
	  handle all hostdev types

	* src/libvirt_private.syms: export a couple of hostdev related
	  ToString() functions

2009-08-13  Daniel P. Berrange  <berrange@redhat.com>

	Make LXC / UML drivers robust against NUMA topology brokenness
	Some kernel versions expose broken NUMA topology for some machines.
	This causes the LXC/UML drivers to fail to start. QEMU driver was
	already fixed for this problem

	* src/lxc_conf.c: Log and ignore failure to populate NUMA info
	* src/uml_conf.c: Log and ignore failure to populate NUMA info
	* src/capabilities.c: Reset nnumaCell to 0 after freeing

2009-08-11  Mark McLoughlin  <markmc@redhat.com>

	Fix some URLs in virsh manpage
	* docs/virsh.pod: don't reference format.html anymore, reference
	  the formatdomain.html etc. pages

	* virsh.1: re-generate

2009-08-11  Chris Lalancette  <clalance@redhat.com>

	Remove a duplicated assignment in Xen PCI parsing.

	Fix up a few minor indentation issues.

	Fix phyp escape_specialcharacters.
	A couple of minor fixes to phyp escape_specialcharacters.  Make it
	a static function (since it's only used in phyp/phyp_driver.c), and
	make it take a dstlen parameter.  This paves the way for removing
	strncpy in the future.

	Make openvzGetVPSUUID take a len.
	Minor fix to openvzGetVPSUUID to make it take a length parameter.
	This ensures that it doesn't make assumptions about the length
	of the UUID buffer, and paves the way for removal of strncpy in
	the future.

	Minor cleanup of error path for c_oneVmInfo.

	Fix up a whitespace in comments in src/console.c

	Fix up a stray whitespace in virHashGrow.

	Run 'cont' on successful migration finish.
	As of qemu 0.10.6, qemu now honors the -S flag on incoming migration.
	That means that when the migration completes, we have to issue a
	'cont' command to get the VM running again.  We do it unconditionally
	since it won't hurt on older qemu.

	Split virDomainMigrate into functions.
	Re-factor virDomainMigrate to split out the version 1 and version 2
	protocols into their own functions.  In reality, the two versions share
	very little in common, so forcing them together in the same function was
	just confusing.  This will also make adding tunnelled migration easier.

	Fix QEMU domain status after restore.
	When doing a restore, we were forgetting to update the state file
	for the VM.  That means that if you do a save/restore, then shut
	down libvirtd, then start it back up, you'll see the state of the
	guest as "paused", even though it is really running.  We were
	just forgetting a "virDomainSaveStatus" call in the restor path.

2009-08-10  Mark McLoughlin  <markmc@redhat.com>

	Handle kernels with no ipv6 support
	If the ipv6 kernel module is not loaded, then we get this when starting
	a virtual network:

	  libvir: Network Config error :
	  cannot enable /proc/sys/net/ipv6/conf/virbr0/disable_ipv6:
	  No such file or directory

	If disable_ipv6 is not present, we should just merrily continue on our
	way.

	* src/network_driver.c: make networkDisableIPV6() not fail if the kernel
	  has no ipv6 support

2009-08-10  Mark McLoughlin  <markmc@redhat.com>

	Set perms on /var/lib/libvirt/boot to 0711
	Allow qemu user to open kernel/initrds in this dir, but still prevent
	others from listing it.

	* libvirt.spec.in: set /var/lib/libvirt/boot perms to 0711

2009-08-10  Mark McLoughlin  <markmc@redhat.com>

	chown kernel/initrd before spawning qemu
	If we're running qemu unprivileged, we need to chown any supplied kernel
	or initrd before spawning it.

	* src/qemu_driver.c: rename qemuDomainSetDiskOwnership() to
	  qemuDomainSetFileOwnership(), pass it a path string instead of a disk
	  definition and use it for chowning the kernel/initrd in
	  qemuDomainSetAllDeviceOwnership()

2009-08-07  Daniel P. Berrange  <berrange@redhat.com>

	Add link to AbiCloud web management system

2009-08-07  Chris Lalancette  <clalance@redhat.com>

	Remove unsafe strncpy from esx_vmx.c
	While trying to remove uses of unsafe strncpy in the tree, I came
	across a couple of usages in the ESX driver.  To my eyes, the snprintf
	replacements do the same thing in less code, and are also safer.

	Tested-by: Mattias Bolte <matthias.bolte@googlemail.com>

2009-08-06  Amy Griffis  <amy.griffis@hp.com>

	Update logging documentation
	* docs/logging.html[.in] try to include a little more description about
	  the corner cases, things someone might get hung up on on.

	Consolidate code for parsing the logging env
	* src/logging.c src/logging.h src/libvirt_private.syms:
	  define new functions virLogSetFromEnv and virLogParseDefaultPriority
	* qemud/qemud.c src/libvirt.c tests/eventtest.c: cleanup to use the
	  unified functions

	Cleanup VIR_LOG_DEBUG parsing in eventtest
	* tests/eventtest.c: don't covert high priority levels to debug level.
	  Consider an invalid priority level setting a setup failure.

	Several fixes to libvirtd's log setup
	* qemud/qemud.c src/logging.[ch]: Similar as for general libvirt, don't
	  convert high priority levels to debug level. Ignore LIBVIRT_LOG_FILTERS
	  and LIBVIRT_LOG_OUTPUTS when they're set to the empty string, otherwise
	  they can override a valid setting from the config file. Send all
	  settings through the parser functions for validation, so that the
	  existence of a bad setting doesn't nullify a good setting that should
	  have applied -- particularly the default output. Keep the order of
	  precedence consistent for all variables between the environment and
	  the config file.  Warn when an invalid log level, filter, or output
	  is ignored.
	* src/libvirt_private.syms: export internally a few convenience functions

	Tighten libvirt's parsing of logging env
	* src/libvirt.c src/logging.c: Don't convert high priority levels to the
	  debug level. Don't parse LIBVIRT_LOG_FILTERS and LIBVIRT_LOG_OUTPUTS
	  when they're set to the empty string. Warn when the user specifies an
	  invalid value (empty string remains a noop).
	* po/POTFILES.in: src/logging.c now include translatable strings

2009-08-06  Matthias Bolte  <matthias.bolte@googlemail.com>

	Cleanup structure name naming

	  just a name change

	Fix memleak if esxOpen fails
	* src/esx/esx_driver.c: if esxOpen failed, priv->transport wasn't freed

	Add proper OOM reporting for esxDomainGetOSType
	* src/esx/esx_driver.c: catch an unchecked strdup in
	  esxDomainGetOSType()

	  shutdown

	Don't try to activate cgroups if not present for LXC

	  the cgroups driver mount isn't available. Improve error
	  logging for resource setup

	Fix configure checks from previous commits
	* configure.in: Don't set AM_CONDITIIONAL until *after* making
	  the checks

	Avoid a warning if compiling without inotify
	* src/xm_internal.c: split the implementations of xenInotifyActive()

2009-08-05  Aron Griffis  <aron.griffis@hp.com>

	Typo and comment fixes
	* docs/schemas/*.rng: the comments were wrong

2009-08-05  Cole Robinson  <crobinso@redhat.com>

	Refresh /etc/xen if inotify wasn't
	* src/xm_internal.c: in case of multiple connections to the xen driver
	  and some clients were not using domain events, the whole /etc/xen
	  monitoring would break leading to disapearing domains.

	Don't loose id on xen domain redefine
	* src/xm_internal.c: bug when redefining a domain, if it was running
	  we would loose its id

	  and add a workaround for a GCC bug in Debian Etch on limit definitions

	Xen Inotify support needs sys/inotify.h
	* configure.in: to activate Xen Inotify checking we need to check for
	  sys/inotify.h availability

	LXC driver requires sched.h and unshare()
	* configure.in: make it check by default for both

	Configure UML support only if sys/inotify.h present
	* configure.in: UML support requires sys/inotify.h so make it check
	  by default.

	Fix libcurl automatic check and ESX status
	* configure.in: if libcurl is not present ESX should be desactivated
	  so default to check for esx

2009-08-05  Matthias Bolte  <matthias.bolte@googlemail.com>

	Extend the ESX URL to habdle ports and GSX
	* src/esx/esx_driver.c src/esx/esx_vi.[ch] src/esx/esx_vmx.[ch]:

	  for the connection and also add a new specific gsx scheme for

	Use virGetHostname instead of gethostname.
	Fix up qemudDomainMigratePrepare2 to use virGetHostname instead of

	there was a latent bug in the handling that could cause a buffer overflow
	on a very long hostname.

	Fix up a minor indentation issue with virDomainMigratePrepare.

	Fix virCapabilitiesDefaultGuestMachine documentation.

	Fix up a silly typo in apibuild.py.

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Add support for attaching network/bridge NICs in QEMU driver
	In order to hotplug a network/bridge backed NIC, we need to first create
	the tap file descriptor, add the tap interface to the bridge and then
	pass the file descriptor to the qemu process using the 'getfd' monitor
	command.

	Once the tapfd has been accepted, we create the network backend using
	host_net_add, supplying the name assigned to the tapfd. If this fails,
	we need to close the tapfd in qemu using the 'closefd' monitor command.

	If the version of qemu does not support the getfd/closefd monitor
	commands we detect "unknown command" in the getfd reply and fail the
	attach operation.

	* src/qemu_driver.c: add support for tapfd based hotplug in
	  qemudDomainAttachNetDevice()

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Add SCM_RIGHTS support to QEMU monitor code
	Add qemudMonitorCommandWithFd() which allows a file descriptor to be
	sent to qemu over a unix monitor socket using SCM_RIGHTS. See the
	unix(7) and cmsg(3) man pages.

	* src/qemu_conf.c: add a scm_fd param to qemudMonitorCommandExtra(),
	  add qemudMonitorCommandWithFd(), implement SCM_RIGHTS support in
	  qemudMonitorSendUnix()

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Use sendmsg() on QEMU monitor socket
	Switch from using write() to using sendmsg() on QEMU's monitor socket
	so that we can add support for SCM_RIGHTS.

	* src/qemu_driver.c: add sendmsg() based qemudMonitorSendUnix() and use
	  it when the monitor fd is a unix socket

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Factor qemudMonitorSend() out of qemudMonitorCommandExtra()
	Add a little helper function to write the monitor command followed by
	carriage return in a single write.

	This doesn't make any real difference, but allows us to more easily

	Clean up error handling in qemudDomainAttachNetDevice()
	In subsequent patches we're going to have a file descriptor to close
	too, so centralize the error handling cleanups to make things easier.

	* src/qemu_conf.c: in qemudDomainAttachNetDevice() consolidate the
	  error handling cleanups together

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Make qemuBuildHostNetStr() take tapfd as a string
	With hotplug, we're going to want to pass a tapfd name rather than an
	actual file descriptor, so prepare the way by passing a string tapfd to
	qemuBuildHostNetStr().

	* src/qemu_conf.h: qemuBuildHostNetStr() takes a string tapfd now

	* src/qemu_conf.c: pass qemuBuildHostNetStr() a string rather than an
	  actual file descriptor

	* src/qemu_driver.c: update qemudDomainAttachNetDevice() for change

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Move vnet_hdr logic into qemudNetworkIfaceConnect() and export it
	* src/qemu_conf.h: export qemudNetworkIfaceConnect()

	* src/qemu_conf.c: move vnet_hdr logic into qemudNetworkIfaceConnect()
	  since we need it for hotplug too

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Only probe qemu for machine types when binary changes
	By probing for qemu machine types, we increased the time of a
	GetCapabilities call from 100us to a whopping 60ms.

	This patch takes the approach of only probing for machine types
	when the mtime of the emulator binary changed since the last time
	the capabilities were generated.

	* src/capabilities.h: cache the emulator binary mtime

	* src/qemu_conf.c: add qemudGetOldMachines() to copy the machine
	  types from the old caps struct if the mtime for the binary hasn't
	  changed

	* src/qemu_conf.h, src/qemu_driver.c: pass the old caps pointer to
	  qemudCapsInit()

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Add canonical machine name to capabilities output
	e.g. <machine canonical='pc'>pc-0.11</machine>

	* src/capabilities.c: output the canonical machine names in the
	  capabilities output, if available

	* docs/schemas/capabilities.rng: add the new attribute

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Probe QEMU directly for machine aliases if not found in capabilties
	Not all possible emulators are actually in the capabilities, so if we
	don't find the supplied emulator we should probe it directly for machine
	types.

	* src/qemu_driver.c: add qemudCanonicalizeMachineDirect() to directly
	  probe an emulator for the canonical machine type

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Canonicalize qemu machine types
	In qemu-0.11 there is a 'pc-0.10' machine type which allows you to run
	guests with a machine which is compatible with the pc machine in
	qemu-0.10 - e.g. using the original PCI class for virtio-blk and
	virtio-console and disabling MSI support in virtio-net. The idea here
	is that we don't want to suprise guests by changing the hardware when
	qemu is updated.

	I've just posted some patches for qemu-0.11 which allows libvirt to
	canonicalize the 'pc' machine alias to the latest machine version.

	This patches makes us use that so that when a guest is configured to
	use the 'pc' machine type, we resolve that to 'pc-0.11' machine and
	save that in the guest XML.

	See also:

	  https://fedoraproject.org/wiki/Features/KVM_Stable_Guest_ABI

	* src/qemu_conf.c: add qemudCanonicalizeMachine() to canonicalize
	  the machine type according to the machine aliases in capabilities

	* src/qemu_driver.c: parse aliases in qemudParseMachineTypesStr()

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Add virCapsGuestMachine structure
	A subsequent commit will add a "canonical" field to this structure,
	this patch basically just prepares the way for that.

	The new type is added, along with virCapabilitiesAlloc/FreeMachines()
	helpers and a whole bunch of code to make the transition.

	One quirk is that virCapabilitiesAddGuestDomain() and
	virCapabilitiesAddGuest() take ownership of the machine list rather
	than duping it. This makes sense to avoid needless copying.

	* src/capabilities.h: add the virCapsGuestMachine struct and use it
	  in virCapsGuestDomainInfo, add prototypes for new functions and
	  update the AddGuest() prototypes

	* src/capabilities.c: add code for allocating and freeing the new
	  type, change the machines parameter to AddGuest() etc.

	* src/libvirt_private.syms: export the new helpers

	* src/qemu_conf.c: update all the machine type code to use the new
	  struct

	* src/xen_internal.c: ditto

	* tests/testutilsqemu.c: ditto

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Probe for QEMU machine types
	Currently we hardcode the QEMU machine types. We should really just
	parse the output of 'qemu -M ?' so the lists don't get out of sync.

	xenner doesn't support '-M ?', so we still need to hardcode that.

	The horrible (const char *const *) is removed in a subsequent patch.

	* src/qemu_conf.c: kill the arch_info*machines tables, retain the
	  hardcoded xenner machine type, add qemudProbeMachineTypes() to
	  run and parse 'qemu -M ?' and use it in qemudCapsInitGuest()

2009-07-27  Mark McLoughlin  <markmc@redhat.com>

	Cleanup qemu binary detection logic in qemudCapsInitGuest()
	There's no need for the hasbase/hasaltbase confusion, just store the
	first binary path found in a variable.

	* src/qemu_conf.c: kill hasbase/hasaltbase logic in qemudCapsInitGuest()

	Commit newly generated docs, after changes from commit 2348cf.

	Add phyp files to POTFILES, to make syntax-check happy.

	test: Implement BlockStats and InterfaceStats
	We fake stats values based on the current time, similar to how it's done
	for cpu time.

	test: Generate net interface names when assigning XML.
	We need interface names to implement InterfaceStats.

	Don't allow NULL paths for BlockStats and InterfaceStats
	Do the check in libvirt.c, to save drivers from the burden. This changes
	behavior slightly in the qemu driver: we no longer explictly error if
	passed an empty string. An error will still be thrown when the device
	lookup fails.

	python: Raise exceptions if virDomain*Stats fail.
	The generator couldn't tell that the stats return values were pointers.

	Fix misc Win32 compile warnings
	GCC >= 4.4 assumes the 'printf' attribute refers to the native
	runtime libraries format specifiers. Thanks to gnulib, libvirt

	Always add -no-kvm and -no-kqemu, for qemu domains
	If the qemu binary supports "-no-kvm" and/or "-no-kqemu", they should
	always be added for plain "qemu" domains.  Previously, we omitted them
	whenever the host and guest architectures implied that they would be
	disabled automatically, but that logic was flawed in some cases
	(such as i686 and x86_64).

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Add support for network device detach
	qemu network devices are hot-unplugged in two stages - first the PCI NIC
	is removed using 'pci_del <pci_addr>' and then the backend is removed
	using 'host_net_remove <vlan> <name>'.

	In order to perform these operations we need to have retained the
	PCI address, backend name and vlan number.

	* src/qemu_driver.c: add qemudDomainDetachNetDevice()

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Retain PCI address from NIC attach
	When we pci_add a NIC, we need to retain the PCI address assigned by
	qemu for using during detach.

	* src/qemu_driver.c: use qemudParsePciAddReply() to pull the PCI
	  address from the pci_add reply

	* src/domain_conf.c: handle storing and parsing the PCI address in the
	  domain state XML file

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Re-factor pci_add reply parsing and parse domain/bus numbers
	The current code for parsing pci_add replies ignores the the domain and
	bus numbers. Re-write the code to rectify that.

	Also, since pci_add is used for NIC hotplug as well ask disk hotplug,
	re-factor the code into a separate function.

	* src/qemu_driver.c: add qemudParsePciAddReply() function which can
	  handle parsing domain and bus numbers

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Remove the network backend if NIC hotplug fails
	If we fail to pci_add a NIC, we should remove the network backend and
	leave things the way we found them. To do that, we pre-allocate a
	host_net_remove monitor command and issue that if the pci_add fails.
	If the remove fails, we just log a warning.

	We can only do this if we have a name for the network backend and
	we know the vlan number its associated with.

	* src/qemu_driver.c: host_net_remove the network backend if the
	  pci_add fails

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Basic qemu NIC hotplug support
	Implement basic NIC hotplug support using the 'host_net_add' and
	'pci_add' qemu monitor commands.

	For now, we don't support 'bridge' or 'network' types.

	Also, if pci_add fails, we currently fail to remove the backend
	which we added.

	Finally, NIC hot-unplug support is missing.

	* src/qemu_driver.c: add qemudDomainAttachNetDevice()

	* src/qemu_conf.[ch]: export qemuBuildNicStr(), qemuBuildHostNetStr()
	  and qemuAssignNames()

	* src/libvirt_private.syms: export virDomainNetTypeToString()

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Make qemuCmdFlags available in qemudDomainAttachDevice()
	qemudDomainChangeEjectableMedia() currently extracts the qemu command

	* src/qemu_driver.c: move the qemudExtractVersionInfo() call from
	  qemudDomainChangeEjectableMedia() to qemudDomainAttachDevice()

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Store the interface vlan number in the domain state
	Currently, an interface's vlan number corresponds to its index in
	the table of network interfaces. That is no longer true when we
	allow devices to be removed.

	To fix this, we store the vlan number in the domain's state XML
	so that it survives libvirtd restarts.

	* src/domain_conf.h: add vlan number to virDomainNetDef

	* src/domain_conf.c: store it in XML as <state vlan='N'/>, defaulting
	  to -1 if this is state saved by a previous version of libvirt

	* src/qemu_conf.c: assign vlan numbers before starting qemu

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Add NIC and hostnet names to domain state XML
	The qemu driver needs to assign and keep track of identifiers for
	network devices so that it can remove them. We need to keep this state
	across libvirtd restarts, but it's not configuration that needs to
	be kept across guest restarts.

	* src/domain_conf.c: parse and format <state nic="foo" hostnet="bar"/>

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Assign names to qemu NICs and network backends
	We need these so that we can remove the devices via the monitor.

	* src/domain_conf.h: add nic_name and hostnet_name to virDomainNetDef

	* src/domain_conf.c: free nic_name and hostnet_name

	* src/qemu_conf.c: add qemuAssignNetNames(), use it if qemu has
	  support for the param and pass the names on the command line

	* tests/qemuxml2argv*: add a test for this

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Add checks for some NIC hotplug related features added in qemu-0.10.0
	Add QEMUD_CMD_FLAG_NET_NAME to indicate that '-net ...,name=foo' is
	supported and QEMUD_CMD_FLAG_HOST_NET_ADD to indicate that the
	'host_net_add' monitor command is available.

	Set both these flags if the qemu version is greater than 0.10.0.
	Checking via the '-help' output would not work for the monitor command
	and even for the command line arg, it would be quite fragile.

	* src/qemu_conf.h: add new flags as aliases of QEMUD_CMD_FLAG_0_10

	* src/qemu_conf.c: set QEMUD_CMD_FLAG_0_10 for versions >= 0.10.0

	* tests/qemuhelptest.c: set QEMUD_CMD_FLAG_0_10 for the appropriate
	  qemu versions

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Factor qemuBuildHostNetStr() out from qemuBuildCommandLine()
	Re-factor this code so that it can be used for NIC hotplug
	too. The awkward prefix and type_sep arguments are needed to
	allow us to do "host_net_add tap vlan=..."

	* src/qemu_conf.c: factor the net backend string formatting
	  code into its own function

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Factor qemuBuildNicStr() out from qemuBuildCommandLine()
	Re-factor this code so that it can be used for NIC hotplug
	too. The awkward arguments are needed to allow use to do
	"pci_add auto nic macaddr=..."

	* src/qemu_conf.c: factor the nic string formatting code into
	  its own function

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Retain disk PCI address across libvirtd restarts
	When we hot-plug a disk device into a qemu guest, we need to retain its
	PCI address so that it can be removed again later. Currently, we do
	retain the slot number, but not across libvirtd restarts.

	Add <state devaddr="xxxx:xx:xx"/> to the disk device XML config when the
	VIR_DOMAIN_XML_INTERNAL_STATUS flag is used. We still don't parse the
	domain and bus number, but the format allows us to do that in future.

	* src/domain_conf.h: replace slotnum with pci_addr struct, add helper
	  for testing whether the address is valid

	* src/domain_conf.c: handle formatting and parsing the address

	* src/qemu_driver.c: store the parsed slot number as a full PCI address,
	  and use this address with the pci_del monitor command

	* src/vbox/vbox_tmpl.c: we're debug printing slotnum here even though
	  it can never be set, just delete it

2009-07-22  Mark McLoughlin  <markmc@redhat.com>

	Add internal XML parsing/formatting flag
	We need to store things like device names and PCI slot numbers in the
	qemu domain state file so that we don't lose that information on
	libvirtd restart. Add a flag to indicate that this information should

2009-07-21  Laine Stump  <laine@laine.org>

	Add interface object list manipulation functions
	* interface_conf.c interface_conf.h: utilities function usful for

	virGetinterface matching of MAC and interface name
	MAC address of a particular interface may change over time, and the
	reduced virInterface object (which contains just name and mac) needs
	to reflect these changes. Since we can't modify the mac address of an
	existing virInterface (some other thread may currently be using it) we
	just create a new virInterface, and let the old one die a dignified
	death when its refct goes to 0.
	* src/datatypes.c: fix the matching and lifetime of virInterface object
	  accordingly

	Add an error code for conflicting mac addresses
	* include/libvirt/virterror.h src/virterror.c: if a driver's

	qemu: Try multiple times to open unix monitor socket
	Unlike the pty monitor (which we know exists since we scrape its path from
	stdout), we have no way of knowing that the unix monitor socket should exist/
	be initialized. As a result, some of my KVM guests randomly fail to start on
	F10 host.

	Try to open the unix socket in a 3 second timeout loop. Ignore EACCES (path
	does not exist if a first time run) and ECONNREFUSED (leftover socket from
	a previous run hasn't been removed yet). Fixes things for me.

2009-07-17  Cole Robinson  <crobinso@redhat.com>

	storage: Implement CreateVolFrom for logical and disk backend.
	With the previous refactoring, this is a simple process, since the global
	'CreateBlockFrom' in storage_backend does all the work.

	storage: Don't try sparse detection if writing to block device.
	We don't gain any space savings, so skip the detection to speed up
	the cloning operation.

	storage: Implement 'CreateBlockFrom' helper.
	Add a 'CreateBlockFrom' in the global storage_backend, which sets up the
	destination block device: CopyFromFD does the rest of the cloning.

	storage: Break out actual raw cloning to separate function.
	The CreateRaw function has some 'file' only assumptions, so break the agnostic
	cloning bits to a separate function.

	storage: cleanup: do away with 'createFile'
	Have storage building functions be definitions of
	virStorageBackendBuildVolFrom: we will need to do this in the future anyways
	if we ever support the flags attribute.

	storage: Move most of the FS creation functions to common backend.
	These will be used by other pool cloning implementations.

2009-07-17  Cole Robinson  <crobinso@redhat.com>

	storage: Refactor FS backend 'create' function choosing.
	Break out separate functions for

	- Determining the supported '*-img' tool,
	- The tool's associated create function,
	- Desired function for cloning (CreateXMLFrom).

	This will be eventually used to unify cloning across all backends.

2009-07-17  Cole Robinson  <crobinso@redhat.com>

	storage: Fix deadlock when cloning across pools.
	We need to unlock the first pool before looking up the second, since the
	search locks every pool it checks.

	storage: disk: Use capacity, not allocation, when creating volume.
	There isn't any way to dictate allocation when creating disk volumes, so
	capacity is the only relevant value.

2009-07-17  Cole Robinson  <crobinso@redhat.com>

	storage: disk: Default to 'ext2' for new volumes.
	Currently, if no format is specified for a new disk volume, we pass the
	invalid value "none" as the FS type to 'parted mkpart'.

	There doesn't seem to be a way to have parted not format the drive, so
	just default to using 'ext2' in this case: this shouldn't cause any harm,
	since we are creating a new partition in the first place.

2009-07-17  Cole Robinson  <crobinso@redhat.com>

	storage: disk: Fix segfault creating volume without target path
	Remove unneeded target path duplication, which could carelessly dereference
	NULL. Make it clear where 'key' is actually filled in.

	storage: disk: Fix parthelper '-g' option handling.
	Typo was breaking 'parthelper -g', preventing disk pool definition.

	build: submodule machinery now works also when no tag is reachable
	The code in cfg.mk to detect when the git submodule was out of date
	worked most of the time, but not when checked out in a certain way.
	* cfg.mk: Extract submodule hash from command output and file,
	and compare only that, since the format of the full line may vary.
	Reported by Mike Burns, with some diagnosis by Daniel P Berrange.

	Rename a bunch of internal methods to clarify their meaning
	This renames a lot of the methods in the remote driver client
	to more accurately reflect their responsibility of IO handling
	vs message handling.

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Simplify remote driver error reporting
	Remove redundant error reporting functions which obscured the
	filename/line number reporting. Removed code which created a
	virDomain/virNetwork object, since those are silently dropped
	in error reporting functions now

	* src/remote_internal.c: Remove error() and errorf() in favour of
	 macros, and remove server_error in favour of direct call

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Refactor message sending to allow code reuse for data streams
	Splits up the 'call' method moving generic IO code out into
	separate method to allow it to be easily reused for sending
	data streams

	* src/remote_internal.c: Split 'call' into two methods, the first
	  with same name serializes a set of method arguments into a
	  message, the second 'remoteIO' takes a pre-serialized messages,
	  sends it and awaits a reply

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Refactor incoming message handling to prepare for data stream support
	* src/remote_internal.c: Rename processCallRecvMsg to
	  processCallDispatch, and move code specific to method replies
	  into processCallDispatchReply, and rename processCallAsyncEvent
	  to processCallDispatchMessage

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Rename 'direction' to 'type' in remote_message_header
	The 'remote_message_header' struct has a mis-leadingly named
	field 'direction'. It is really a reflection of the type of
	message, and some types can be sent in either direction. Thus
	the field is more accurately named 'type'. No function change.

	* qemud/remote_protocol.x: Rename 'direction' to 'type' in
	  'remote_message_header. Write better docs describing the
	  message header field semantics & usage
	* qemud/remote_protocol.c, qemud/remote_protocol.h: Regenerate
	* qemud/remote.c, qemud/dispatch.c, src/remote_internal.c
	  Update to reflect rename of 'direction' to 'type'

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Define an API for registering incoming message dispatch filters
	All incoming messages currently get routed to the generic method
	remoteDispatchClientRequest() for processing. To allow incoming
	data stream messages to bypass this and be routed to a specific
	location, a concept of dispatch filters is introduced.

	* qemud/qemud.h: Add a qemud_client_filter struct and a callback
	  qemud_client_filter_func. Maintain a list of filters on every
	  struct qemud_client
	* qemud/qemud.c: Move remoteDecodeClientMessageHeader() out of
	  qemudWorker() into qemudDispatchClientRead(). Check registered
	  message filters in qemudDispatchClientRead() to decide where
	  to send incoming messages for dispatch.

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Split out code for handling incoming method call messages
	The remoteDispatchClientRequest() method is currently hardwired to
	assume there is only one type of incoming message, a method call.
	To allow for alternate types of incoming messags, the code that is
	specific to method calls is being split into a separate method
	remoteDispatchClientCall

	* qemud/dispatch.c: Move method call specific code out into
	  remoteDispatchClientCall. Add a helper remoteSerializeError
	  for returning error messages to client

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Change the way client event loop watches are managed
	The current qemudRegisterClientEvent() code is used both for
	registering the initial socket watch, and updating the already
	registered watch. This causes unneccessary complexity in alot
	of code which only cares about updating existing watches. The
	updating of a watch cannot ever fail, nor is a reference to the
	'qemud_server' object required.

	This introduces a new qemudUpdateClientEvent() method for that
	case, allowing the elimination of unneccessary error checking
	and removal of the server back-reference in struct qemud_client.

	* qemud/qemud.h: Remove 'server' field from struct qemud_client.
	  Add qemudUpdateClientEvent() method. Remove 'update' param
	  from qemudRegisterClientEvent method
	* qemud/dispatch.c, qemud/qemud.c, qemud/remote.c: Update alot
	  of code to use qemudUpdateClientEvent() instead of
	  qemudRegisterClientEvent(). Move more logic from remoteRelayDomainEvent
	  into remoteDispatchDomainEventSend.

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Move queuing of RPC replies into dispatch code
	This removes an assumption from qemudWorker() code that every
	incoming message will generate a reply.

	* qemud/dispatch.c: remoteDispatchClientRequest now has responsibility
	  for queuing the reply message to the RPC call
	* qemud/qemud.c: Do not queue the RPC call reply in qemudWorker(),
	  allowing remoteDispatchClientRequest() to take care of it

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Change code generator to give async event messages their own postfix
	The naming convention for structs used in the RPC layer is for
	incoming requests to be called XXXX_args, and the associated
	outgoing reply to be called XXXX_ret.  Asynchronously emitted
	messages (eg events) are re-using the XXXX_ret naming scheme.
	This patch changes that such that async messages are XXXX_msg,
	and stops adding entries for them in the dispatch table, avoiding
	the need for a dummy no-op implementation.

	* qemud/remote.c: Remove dummy remoteDispatchDomainEvent, no
	  longer required. Update to replace remote_domain_event_ret
	  with xdr_remote_domain_event_msg
	* qemud/remote_protocol.x: Rename remote_domain_event_ret to
	  remote_domain_event_msg
	* qemud/remote_generate_stubs.pl: Adding handling for new
	  XXX_msg structs.
	* src/remote_internal.c: Rename remote_domain_event_ret to
	  remote_domain_event_msg
	* qemud/remote_dispatch_prototypes.h, qemud/remote_dispatch_ret.h,
	  qemud/remote_dispatch_table.h, qemud/remote_protocol.h,
	  qemud/remote_protocol.c: auto-regenerate

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Separate code for encoding outgoing remote message headers
	Introduces an API for encoding the header field for outgoing messages
	allowing some duplicated code to be eliminated

	* qemud/dispatch.c, qemud/dispatch.h: add remoteEncodeClientMessageHeader
	  for encoding message header. Update remoteDispatchClientRequest to
	  use this method.
	* qemud/remote.c: Update remoteDispatchDomainEventSend to use the
	  generic remoteEncodeClientMessageHeader() for encoding event
	  message hedaders. Push some logic from remoteRelayDomainEvent
	  down into remoteDispatchDomainEventSend.

2009-07-16  Daniel P. Berrange  <berrange@redhat.com>

	Decode incoming request header before invoking dispatch code
	Separate the decoding of incoming request header out from the
	dispatch code. This will allow later code to making dispatcher
	routing decisions based on the header field data.

	* qemud/dispatch.c, qemud/dispatch.h: Add remoteDecodeClientMessageHeader
	  API for decoding the header of a client message. Update the
	  remoteDispatchClientRequest method to assume a pre-decoded
	  header.
	* qemud/qemud.h: Include a 'remote_message_header' field in
	  'struct qemud_client_message' for pre-decoded header data
	* qemud/qemud.c: Decode the incoming client message header before
	  invoking remoteDispatchClientRequest

	* qemud/Makefile.am: Add dispatch.c to build
	* qemud/qemud.c: Include dispatch.h
	* qemud/qemud.h: Remove remoteDispatchClientRequest, remoteRelayDomainEvent
	  now in dispatch.h
	* qemud/remote.c: Remove remoteDispatchClientRequest, remoteRelayDomainEvent
	  now in dispatch.c, and dispatch_args, dispatch_ret, dispatch_fn & dispatch_data
	  now in remote.h
	* qemud/remote.h: Add typedefs for dispatch_args, dispatch_ret,
	  dispatch_fn, dispath_data. Add remoteGetDispatchData() API

2009-07-10  Jim Meyering  <meyering@redhat.com>

	build: automatically rerun ./bootstrap when needed
	When "git pull" (or any other operation) brings in a new version of the
	gnulib git submodule, you must rerun the autogen.sh script.  With this
	change, "make" now fails and tells you to run ./autogen.sh, when needed.
	* autogen.sh: Maintain a new file, .git-module-status, containing
	the current submodule status.  If it doesn't exist or its content
	is different from what "git submodule status" prints, then run
	./bootstrap
	* .gitignore: Add .git-module-status
	* cfg.mk: Diagnose out of date submodule and fail.
	* README-hacking: Update not to mention bootstrap.
	* Makefile.am (MAINTAINERCLEANFILES): Add .git-module-status,
	so that "make maintainerclean" will remove it.

	build: make autogen.sh use autoreconf -if
	* autogen.sh: Use "autoreconf -if" instead of open-coding it with
	manual and unconditional invocation of each separate tool.

2009-07-10  Mark McLoughlin  <markmc@redhat.com>

	Use virDomainChrTypeFromString() instead of open coding
	* src/domain_conf.c: replace open coded chr type parsing with
	  virDomainChrTypeFromString(), retaining the existing semantics
	  where unknown types are silently mapped to the "null" type and
	  "pty" is used if none is specified

2009-07-10  Mark McLoughlin  <markmc@redhat.com>

	Switch to using a unix socket for the qemu monitor
	We keep support for the pty based monitor so that we can re-connect
	to VMs started by older versions of libvirtd.

	* src/domain_conf.c: handle formatting and parsing unix monitors

	* src/qemu_driver.c: add qemudOpenMonitorUnix(), remove the monitor
	  pty path searching from qemudFindCharDevicePTYs(), switch
	  qemudStartVMDaemon() and qemuDomainXMLToNative() to using a unix
	  monitor

	* tests/qemuxml2argvtest.c: switch to using a unix monitor

	* tests/qemuxml2argvdata/qemuxml2argv-*.args: update test data

2009-07-10  Mark McLoughlin  <markmc@redhat.com>

	Add the monitor type to the domain state XML
	There are no functional changes in this patch apart from adding the
	monitor type to the state XML.

	The patch mostly consists of switching to use virDomainChrDef every
	where to describe the monitor.

	* src/domain_conf.h: replace monitorpath with monitor_chr

	* src/domain_conf.c: handle parsing the monitor type and initializing
	  monitor chr

	* src/qemu_conf.[ch]: make qemudBuildCommandLine take a
	  virDomainChrDefPtr and use that to build the -monitor parameter

	* src/qemu_driver.c: split pty specific and common code from
	  qemudOpenMonitor, have qemudStartVMDaemon() initialize monitor_chr

	* tests/qemuxml2argvtest.c: update for qemudBuildCommandLine() change

2009-07-10  Mark McLoughlin  <markmc@redhat.com>

	Minor qemu monitor coding style fixes
	* src/qemu_driver.c: use a consistent coding style for function
	  definitions

	Don't leak vm->monitorpath on re-connect
	* src/qemu_driver.c: vm->monitorpath is already initialized in the case
	  of re-connect, so move the initialization for the normal startup case
	  out of the common code

2009-07-10  Jim Meyering  <meyering@redhat.com>

	build: update from gnulib, for latest maint.mk
	* gnulib: Update submodule to latest.
	This fixes the make syntax-check failure whereby sc_po_check
	would complain about cfg.mk.

	avoid a "make syntax-check" failure
	* .x-sc_avoid_if_before_free: Ignore *all* ChangeLog files,
	now, including ChangeLog-old.

2009-07-09  Daniel P. Berrange  <berrange@redhat.com>

	Fix wierd build problems due to autopoint overwriting gnulib m4
	* Makefile.am: List -I m4 first, in ACLOCAL_AMFLAGS
	* .gitignore: ignore gnulib/, ChangeLog, *rej, *orig, *#*# (emacs
	  temporary files)

2009-07-09  Jim Meyering  <meyering@redhat.com>

	doc: clone+build instructions
	* README-hacking: New file.
	* bootstrap: Remove obsolete comments.

	build: adjust aclocal's search patch to prefer gnulib's m4 files.
	* Makefile.am (ACLOCAL_AMFLAGS): Search gnulib/m4/ before m4/.

2009-07-08  Jim Meyering  <meyering@redhat.com>

	generate ChangeLog from git logs into distribution tarball
	No longer maintain a version-controlled ChangeLog file, but do
	continue to include a ChangeLog file in distribution tarball.
	* Makefile.am (gen-ChangeLog): New rule.
	(dist-hook): Depend on it.
	(EXTRA_DIST): Add ChangeLog-old.
	* bootstrap (modules): Add gitlog-to-changelog.
	* ChangeLog: Remove file.  Renamed to...
	* ChangeLog-old: ...this.  New file.
	* autogen.sh: Touch ChangeLog, to ensure it exists.  For automake.

	use gnumakefile and maintainer-makefile modules from gnulib
	* bootstrap (modules): Add gnumakefile and maintainer-makefile.
	* GNUmakefile: Remove file, now provided by gnulib.
	* Makefile.maint: Remove.  Replaced by maint.mk from gnulib.
	.gitignore: Add GNUmakefile and maint.mk.
	* cfg.mk (prev_version_file): Disable this feature.
	Setting this to /dev/null avoids an otherwise harmless diagnostic.

	remove all .cvsignore files

2009-07-08  Jim Meyering  <meyering@redhat.com>

	make .gnulib a submodule
	This makes it so we record (via a git submodule)
	a snapshot of whatever version of gnulib we're using,
	and none of gnulib sources are in the libvirt repository.
	The result is that we have as much reproducibility as when
	we version-controlled imported copies of the gnulib sources,
	but without the hassle of the manual process we used when
	syncing with upstream.

	Note that when you clone libvirt, you get only the libvirt
	repository, but when you first run ./bootstrap, it clones
	gnulib (at the SHA1 recorded via the submodule), creating
	the .gnulib/ hierarchy.  Then, the bootstrap script runs
	gnulib-tool to populate gnulib/ with the files that make
	up the selected modules.

	Put the following in your ~/.gitconfig file.
	[alias]
	  syncsub = submodule foreach git pull origin master

	The update procedure is simple:
	  git syncsub
	  ...build & test...
	  git commit -m 'gnulib: sync submodule to latest' .gnulib

	* .gitmodules: New file.
	* .gnulib: Initialize.
	* bootstrap: Set up to use the new submodule.
	Stop using --no-vc-files.
	Don't remove .gitignore files.
	Don't use or create .cvsignore.
	Diagnose an invalid --gnulib-srcdir=DIR argument.
	* build-aux/vc-list-files: Delete file, now pulled from gnulib.
	* build-aux/useless-if-before-free: Likewise.
	* po/POTFILES.in: Remove gnulib/lib/gai_strerror.c, since
	it no longer contains translatable strings.
	* gnulib/*: Remove gnulib/ hierarchy.

2009-07-08  Jim Meyering  <meyering@redhat.com>

	skip some of gnulib's new rules
	* cfg.mk (local-checks-to-skip): Add these: sc_error_message_uppercase,
	sc_program_name, sc_require_test_exit_idiom, sc_makefile_check.

	Prepare to use maint.mk from gnulib
	Since Makefile.maint will soon come from gnulib's maint.mk,
	sync Makefile.maint to have the same contents (modulo minor
	things).  In syncing it, we have to remove some libvirt-specific
	rules.  Since we want to keep them (of course), put those in cfg.mk.
	* Makefile.maint: Merge from gnulib's maint.mk.
	* cfg.mk (sc_avoid_write): New rule.  From Makefile.cfg.
	(sc_prohibit_strcmp_and_strncmp): Likewise, and rename.
	(sc_prohibit_asprintf, sc_prohibit_VIR_ERR_NO_MEMORY): Likewise.
	(sc_prohibit_nonreentrant): Likewise.
	(sc_prohibit_ctype_h): Likewise.
	(sc_TAB_in_indentation, sc_avoid_ctype_macros): Likewise.
	(sc_prohibit_virBufferAdd_with_string_literal): Likewise.
	(sc_prohibit_gethostby): Likewise.
	(sc_libvirt_unmarked_diagnostics): Likewise.  Also, rename the
	rule, inserting "_libvirt", since this rule is a specialization of
	the one in gnulib.
	* GNUmakefile: Include cfg.mk, not Makefile.cfg
	* .x-sc_prohibit_strcmp_and_strncmp: New file.
	* Makefile.am (EXTRA_DIST): Add .x-sc_prohibit_strcmp_and_strncmp

	* Makefile.cfg: Rename to...
	* cfg.mk: ...this.  New file.

2009-07-08  Jim Meyering  <jim@meyering.net>

	use automake-1.11's silent-rules option, when possible
	Don't use mylibtool, (subsumed by automake's silent rules)
	Its use was causing a non-srcdir build to fail.
	* Makefile.am (EXTRA_DIST): Remove mylibtool.
	* configure.in: Don't use mylibtool.

	* configure.in: Use AM_SILENT_RULES([yes]),
	but only if that m4 macro is defined.
	Thus, it works even on systems that lack automake-1.11.
	Daniel Berrange suggested adding the conditional, so that
	we don't have a hard requirement on 1.11, e.g., for RHEL5.

2009-07-08  Jim Meyering  <meyering@redhat.com>

	fix another failing "make distcheck" (qemuhelptest)
	It failed in a non-srcdir build because those 5 sample output
	files were not included in the distribution tarball.  Include them.
	* tests/Makefile.am (qemuhelpdata, EXTRA_DIST): Include these:
	kvm-74, kvm-86, qemu-0.10.5, qemu-0.9.1, qemu-kvm-0.10.5.

	fix failing "make distcheck"
	* docs/Makefile.am (xml): Distribute testpool.xml and testvol.xml,
	which are referenced from testnode.xml.

2009-07-08  Daniel P. Berrange  <berrange@redhat.com>

		element for testing graphics adapter
		* tests/qemuxml2argvtest.c: Add QEMUD_CMD_FLAG_VGA flag
		* tests/qemuxml2xmltest.c: Add missing graphics-vnc-sasl/tls tests

	Support <video> tag for defining VGA card properties
	 * docs/schemas/domain.rng: Define <video> element schema
	 * src/domain_conf.c, src/domain_conf.h, src/libvirt_private.syms:
	   Add parsing and formatting for <video> element

2009-07-08  Daniel Veillard  <veillard@redhat.com>

	Report the object name on lookup error
	* src/network_driver.c src/node_device.c src/storage_driver.c:
	  many places in the code reported 'No xxx with matching name" after
	  a Lookup error without reporting the name used by the failed lookup

2009-07-08  Harshavardhana  <harsha@gluster.com>

	Add new net filesystem glusterfs
	* src/storage_conf.c src/storage_conf.h: adds glusterfs to the list
	  of network storage
	* libvirt.spec.in: adds the dependency on glusterfs-client

2009-07-07  Paolo Bonzini  <pbonzini@redhat.com>

	Avoid raising an internal error
	* src/qemu_conf.c: when connecting an interface if it reference
	  an undefined network, then we used to raise an internal error.

2009-07-07  Daniel Veillard  <veillard@redhat.com>

	Fix informations about previous git server
	* docs/downloads.html[.in]: update the secton about
	the server on git.et.redhat.com based on the plans
	Jim posted.

	Fix python examples to use read-write conn
	* docs/examples/python/domstart.py python/tests/create.py:
	The two example were broken as they needed full-access connection
	but only opened read-only connections

2009-07-06  Daniel Veillard  <veillard@redhat.com>

	update download informations after switch to git * docs/downloads.html docs/downloads.html.in: update download   informations after switch to git daniel
