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 things. Adrian -- Adrian Chadd - adrian@freebsd.org
