Hi Juergen,

Sorry for huge delay. It looks that I am recovering slowly and
probably I will have more time for reviews.

AIUI PVH is quite generic idea and can be implemented by different
virtualization platforms. IIRC Maran Wilson works on PVH for KVM.
So, would not it make more sense to have platform independent GRUB2
PVH code and then on top of that build Xen and KVM support? Could
you do that?

Thank you for your work.
