The hardware has nothing to do with it. It works because the hypervisor
API has a spec and is maintained compatibly. Its not entirely hardware
architected either, it has chunks of interfaces that are not present
hardware level or not meaningful at that level - the paging assists for
example are purely a hypervisor interface as are hipersockets.
