My bad, I use paravirtualized guests. It's just that I didn't know its
termed as PV. Virt-manager, I think it automates the conversion of a linux
kernel to PV, because when I select a linux installation source tree it
takes some-time fetching and converting the kernel and initrd, or it may
even replace the kernel and initrd with the xen-domU kernel and initrd.

I haven't tried the P2V method. That will be a fun experiment. Will try
that one soon.
