Well, I am not sure where this is coming from at all.  Technically speaking
F-12 doesn't support any xen guests, as we have no dom0, though it will
happily run *as* a xen guest in either paravirt or fullvirt.
Perhaps the intention was to point out that systems without hardare virt
capabilities cannot run xen either, since we don't ship a dom0?
