[Qemu-devel] [Bug 1285708] [NEW] FreeBSD Guest crash on boot due to xsave instruction issue

[Jesse Pretorius]

Public bug reported:

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: https://lkml.org/lkml/2014/2/22/58

Can this fix be included in Precise ASAP!
