[kernel-xen] UEFI hardware wanted

Thanks Colin,

I'm pretty sure I know *why* it didn't work - although I have a lot of
work to do to make sure it works as intended.

I've just synced up new packages to the EL7 version of my packages that
are under testing that I get working ok with a non-EFI system - but it
should also work with EL7 / grub2 / UEFI. Should.

To make sure it works, I need some physical kit to work with - otherwise
I wouldn't be confident in saying that it is stable.

Hopefully, it will translate to working under EL6 / UEFI as well - but
right now, I can't say anything concrete.

As for the other questions, I know very little about KVM - and I
wouldn't even bother with it. However that's my preference.
