Comment 1 for bug 824167

The templates tweak dhclient.conf so that the container should send its hostname. If you have dnsmasq running (i.e. if you are connecting your clients to a libvirt bridge), and your host has 'nameserver 192.168.122.1' at the top, then you should be able to 'ssh <container>.'.

Since lxc is not setting up your network environment, I'm not sure that it is proper for lxc itself to do any more. Does the above work for you?
