Bug description:
When trying to boot a working FreeBSD 9.1/9.2 guest on a kvm/qemu host
with the following command:
kvm -m 256 -cdrom FreeBSD-9.2-RELEASE-amd64-disc1.iso -drive
file=FreeBSD-9.2-RELEASE-amd64.qcow2,if=virtio -net nic,model=virtio
-net user -nographic -vnc :10 -enable-kvm -balloon virtio -cpu
core2duo,+xsave
The FreeBSD Guest will kernel crash on boot with the following error:
panic: CPU0 does not support X87 or SSE: 0
When launching the guest without the cpu flags, it works just fine.
This bug has been resolved in source:
