As far as I know, libvirt always assumes that the guest is responsible
for obtaining an IP address e.g. using DHCP (which makes perfect sense in
the context of virtualisation technologies which emulate a PC). So at
this time, I think you need to have a script which runs dhclient before
running sshd.

Another alternative is just to run a full Linux distribution inside LXC,
and then the LXC guest's init will be responsible for bringing up the
network. However, I haven't managed to do this (init just dies
immediately when I've tried it, on Fedora 12).
