What can be done is running Xen PVM inside Xen HVM. For that, you set up
a domain with Xen HVM, running a suitable Linux distro. Then, inside
that HVM domain, you can install Xen and create PVM domains. I tested
that for fun & giggles with IIRC Xen 3.1 and it does work. Be warned,
however, that the PVM domains will probably be very slow.
