== The tunctl problem ==
Unfortunately, you are limited to [http://forum.openvz.org/index.php?t=msg&th=4280&goto=22066&#msg_22066 non-persistent tunnels inside the VEs]:
<pre>
# tunctl
enabling TUNSETPERSIST: Operation not permitted
</pre>
Get a patched tunctl [https://github.com/xl0/uml-utilities here], and run it with the -n option. It will create a non-persistent tun device and sleep instead of terminating, to keep the device from deletion. To remove the tunnel, kill the tunctl process.
