I was able to go through creating PV DomUs images via corresponding pygrub's profiles for F10,CentOS 5.2,SNV_106 (64-bit all).
However, only Solaris Nevada PV DomU gets loaded via standard
pygrub profile.
Attempt to load F10 PV:-

Mask X86_FEATURE_XSAVE in cpuid leaf 1, ecx, as we don't allow guests to
use it (by setting cr4.OSXSAVE).
This prevents crashes in pvops dom0 kernels, as new versions of Linux try
to use this feature.
(This patch deals with dom0 cpuid; I'm not sure where the right place to
set up the default mask for domU is.)
