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:

  Can this fix be included in Precise ASAP!
