I still plan to make xenner handle that use case.
You can also run xen inside kvm via nested svm.

HVM is more difficuilt. Xen considers the tools <-> hypervisor
interface private, i.e. it is a moving target. For PV this isn't a big
issue as there is little reason to actually change something. HVM
usually has quite a few changes from release to release though, due to
emulation changes/improvements and other reasons.

Gerd
