Dom0 itself is a virtual domain. I think the function of HVM should not
on the dom0. So the question is if without any interference from dom0,
helps HVM to function, such as creating a virtual disk for HVM, PCI,
Does this need modification of xen?

I am not sure if that is possible, but i doubt possible atleast right
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?
