Actually what I meant was to *replace* kvmconfig with virtconfig and
then add the Xen stuff to it, i.e. to have a single thing to maintain
for all virt platforms, rather than end up with all 3 options.

I think the overhead of having some Xen stuff enabled in .config when
running on KVM and vice versa is small.
