Title:
FreeBSD Guest crash on boot due to xsave instruction is
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 configurat
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.

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.

As a workaround use the 'host' cpu type so the proper bits are enabled:

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.
