My first attempt was to install avahi-daemon on host and container, replace hostname in container config, fstab, /etc/hosts, /etc/hostname and dhclient.conf with some unique id. This worked in VirtualBox, but for some reason not on a real machine.

Hi Stéphane,

I should note that I'm working with a server installation of 12.04, and packages dnsmasq and resolvconf are actually not installed by default. I've added them but I'm not sure what's next. So I think I'm missing some configuration that you assume on your blog.

Eg output of host $(echo %h | sed "s/\\.lxc//g") 10.0.3.1 is

Using domain server:
Name: 10.0.3.1
Address: 10.0.3.1#53
Aliases: 

Host %h not found: 3(NXDOMAIN)

Thanks,
Marko
