Since the Xen hypervisor doesn't run on Dom0 (it's the other way
around), to get nested virtualizations, you would have to run a second
Xen hypervisor on top of the first hypervisor. AFAIK, Xen hasn't been
ported to the PV API, it needs the full, real hardware.

Or run a Xen HVM and then you can run PVs inside of that (I've heard). We had a discussion here quite a long time ago about this.
I'm not sure why Xen drags on nesting as other VM solutions provide it through hardware support (Mostly AMD). I've had the need for nested VMs so I can teach VMs. Each student would have their own VM which would allow them to act as though it were a Dom0 and run other VMs including the network. I'll be testing this out later this quarter.

Some people, when confronted with a problem, think "I know, I'll use Windows."
Now they have two problems.
