Do you mean running xserver in domain0? You should better setup separate
domain for it.
But are you sure that such a setup will be usable and fast enough? I'm
definitely interested in results, anyway.

If I'm not mistaken, you can start up new VMs only from domain0 or
through HTTP interface, So you can easily firewall all traffic inside
domain0 to local port 8000 (except for 127.0.0.1/32).
