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

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?
