Domains don't stack. There's no concept of one domain running on top of
a different one, not even with the original dom0.

But many of the tasks dom0 performs on behalf of domU's could be done by
other domUs as well. Primary example would be I/O virtualization for
normal, non-privileged guests.

So the dependency graph you can build for a 'service' model is *much*
more flexible than the rather static 3-level block scheme depicting the
bare binary interface.

That's maybe not the answer you were looking for.

If you're rather looking for recursive virtualization, I don't think
that's going to fly all that well either.

Daniel
