Not sure if this is a FreeBSD or Virtualbox bug. When you create a new virtual machine in Virtualbox and you specify you are running FreeBSD as guest system, Virtualbox by defaults disables the IO APIC. This crashes the FreeBSD loader with a "AE_ALREADY_EXISTS, unable to install system control interrupt handler" message. Screenshot: http://postimage.org/image/zgtgx57o/ When enabling the IO APIC manually in the Virtualbox VM settings, it does continue to boot FreeBSD. >How-To-Repeat: - install Virtualbox - create a new VM. - in the wizzard specify you are running FreeBSD as guest OS - attach the FreeBSD 9.0 beta 3 AMD64 install CD to the VM - start the VM >Fix: Workaround: - in virtualbox: click the VM - press the "settings" button - "system" -> "motherboard" tab -> enable the 'extended features: "Enable IO Apic"' checkbox. >Release-Note: >Audit-Trail: Responsible-Changed-From-To: freebsd-amd64->vbox Responsible-Changed-By: eadler Responsible-Changed-When: Sun Oct 16 22:57:31 UTC 2011 Responsible-Changed-Why: over to (correct) maintainer http://www.freebsd.org/cgi/query-pr.cgi?pr=161419 >Unformatted:
