Wasn't part of the original KVM idea to support a "hypervisor"
interface to a parent, sort of Xen-like, providing interrupt, VM and
inter-VM "IPC" hooks?

I remember seeing this stuff a while back but for some reason all I
read about KVM - outside of what Redhat are doing with it and Xen now
- focuses on hardware virtualisation.

A BSD-licenced KVM hypervisor + FreeBSD kernel might be an interesting
project. I'm pretty sure Rusty wrote a very very lightweight KVM
hypervisor as a demonstration which may serve as a starting point for
