Description of problem:
Since recently patching our oVirt Hosts, I´ve been having trouble running FreeBSD guests with more than one virtual core or socket. I have managed to take a screenshot of how it looks like when it panics when booting kernel, right after ACPI:
I´ve tried this with similar results using 8.2-RELEASE, 8.3-RELEASE, 9.0-RELEASE and 9-STABLE.
If I edit the guest to have only one virtual core or socket, it boots up without issue.
This issue does not present itself when using a lower version kernel, works with kernel-3.3.4-5.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have kernel-3.3.4-5 and a FreeBSD guest with >1 CPU
2. Update to kernel-3.6.7-4
Thanks for the report, there should be a resolution soon.
Can you load the kvm-intel.ko module with emulate_invalid_guest_state parameter set
as 0, ie:
Its very likely the cause for this are instruction emulation upstream (emulation of invalid guest state by default).
These are being fixed upstream. Once that is completed, it will be necessary to backport
In the meantime, loading kvm-intel.ko with emulate_invalid_guest_state=0 should work around the problem (tested locally on kvm.git as of dec/2012).

"instruction emulation changes upstream".
