We only create a few device nodes by default:

  http://libvirt.org/drvlxc.html#devnodes

You can ask for more using this syntax:

  http://libvirt.org/formatdomain.html#elementsHostDevCaps

eg

  <hostdev mode='capabilities' type='misc'>
    <source>
      <char>/dev/net/tun</char>
    </source>
  </hostdev>
