I think there are a couple of tools around that will do what you're
asking - essentially clone the VM on the fly on another host. One thing
you need to be careful of here is that many of the attributes of the VMs
may be identical - for example, the MAC address of the cloned domU will
be the same on both hosts, meaning that, if the domUs share the same
network interface, you'll end up with a duplicate MAC and probably
duplicate IP addresses. Also, the disk used by the domU will also be
exactly the same, which is very, very dangerous - this usually ends in
corruption of the filesystem on the domU disk. Whatever tool you find
for this needs to change MAC addresses and needs to copy the disk or use
the disk device in such a way that does not affect the first one.
What, exactly, are you trying to accomplish in this scenario?
