Also LXC domains can use the nwfilter subsystem and make use of the IP 
address detection in the same way as Qemu does and with that also an LXC 
domain's XML should display the IP_LEASE information now. I haven't used 
LXC myself, though. I guess for your purposes someone would have to 
extend the perl wrappers to provide access to that information.

Let me know when you tested it. I have pretty high confidence in the 
correctness of the code now :-)
