As physical boxes gain more and more processing capability it makes no sense

Libvirt will support nested VM's that pass through the VT capabilities to
the next level.  So it makes sense that Xen should be able to do the same
thing and pass through the cpu VT capabilities to other hypervisors.  Is
there some law of the universe that prevents this?

While KVM could probably do it, Xen currently can't. You might be able
to get more answers about "why" and possible time line to support it
(if any available) from xen-devel.
I'll bring the thread over to xen-devel.
