I am not sure if that is possible, but i doubt possible atleast right now.
hypervisor itself is pretty thin and minimal and does not contain most
of the drivers.Directly booting a HVM(e.g a linux kernel on XYZ
distro) means giving hardware control to that HVM drivers which is not
something intended. What happens if there are two HVM?
