CC'd to libvir-list, since this is really a libvirt question.

The trouble with the architecture you've described is that it relies
on the IP source address for authentication, one of those things you
should never do if you care about security:


Maybe because it's TCP, and it's a closed system with a firewall, you
can get away with it.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.
