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

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.

Thanks for reporting this bug. Given the lkml.org fix, I assume this is
in fact a kernel bug, so assigning it as such.
This is presumably fix-released in utopic, but SRU-able to precise and
trusty's backport kernels. I'm not clearn on how that process works, so
leaving it like this.

As a workaround use the 'host' cpu type so the proper bits are enabled:
-cpu host,+xsave

You don't need "+xsave", "-cpu host" just works.
The bug is invalid. You are requesting a CPU that doesn't exist (a
core2duo that supports XSAVE), and the guest's behavior is probably not
going to be well defined.

Quite right - our workaround was to switch to using the host
capabilities instead of the compatibility fallback. However, the
decision for a compatibility fallback was automatically made and
included the above combination. I don't know where that bug should sit.

Testing with the identified patch doesn't solve the issue, in addition
looking at the cpu flags (core2duo +xsave) this may not be a valid
configuration since xsave assumes additional features will be there
(instead of creating an older cpu model with xsave.) Therefore I believe
this is a configuration issue.
The comment above in #4 assumes your host has the correct cpu features, you can always run something like:
kvm -cpu host,+xsave,check to check if are issues with the host plus additional features settings. In addition I've been able to use '-cpu SandyBridge,+xsave' and this also works.
Marking this 'Won't Fix' as there is a clear workaround (use another CPU
model), and this configuration may not be valid.
Thanks
