Exactly. The hypervisor i must support nested virtualization.

Your picture is exactly what I mean.

Do you mean you want to migrate the guests from m.h to n.i.h? Or do you mean you want to migrate the hypervisor itself from running on bare metal to running in a VM?

I think the Intel guys have been looking at the first (migrating a VM running on Xen-on-metal to Xen-on-Xen). Not sure about AMD.

I don't think anyone has tried the second even with a normal operating system, much less a hypervisor with things running on top of it.
