IP addresses are something that machines - virtual or physical - set for
themselves.  It might be statically configured, or it might be from a
dhcp server, but either way the domain itself needs to do the setting.

I guess in principle dom0 could stick the ip address into xenstore and
the domU could fetch it from there, but AFAIK there's no mechanism to do
