This appears to be an AVX instruction which none of my test systems
appear to support which is probably why I cannot reproduce this.

Which dom0 kernel are you running?

If you boot the same kernel natively what happens when you run pygrub?
(this should work natively, although obviously you won't be able to
actually start a VM).

Can you please provide /proc/cpuinfo and the output of dmesg for both
the native and Xen case and in the xen case the output of "xl dmesg".

Lastly it might be worth trying xsave=0 on your hypervisor command line.

Ian.
