RE: [Xen-devel] Is it possible that Xen starts without Domain0

["Hu Jia Yi" <jyhu@xxxxxxxxx>]

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?

Thanks
