I don’t know anyone is working on porting Xen to dragonfly. I don’t even know whether dragonfly runs as domU (i.e. guest) in Xen.

I believe it’s much more difficult to port Xen dom0 to dragonfly than porting a type-2 hypervisor (like NVMM). But I don’t know much about Xen and thus don’t know the details.

I know NetBSD supports Xen dom0 and domU, FreeBSD supports Xen domU, but I’m not sure whether FreeBSD supports dom0.
