OpenVPN failed to start

[WolfertK]

LS,

I would like to use the VPN module in my Plesk installation, however I can't seem to get it enabled.

These are the preferences set:
Remote address: <blank>
Remote UDP port: <blank>
Local UDP port: 1194
Local peer address: 10.8.0.1
Remote peer addres: 10.8.0.2

This is the error Plesk gives me:
Error: There was a problem starting or stopping the OpenVPN daemon:
psa-vpn: OpenVPN failed to start

In /var/log/messages I found this error:
Jun 7 16:22:49 vps479 openvpn[20413]: OpenVPN 2.0.1 i686-pc-linux [CRYPTO] [LZO] [EPOLL] built on Jun 13 2006

Jun 7 16:22:49 vps479 openvpn[20413]: Exiting

At first I figured it was only a matter of changing permissions, but even with these settings the same error keeps returning.
[root@vps479 openvpn-2.0.9]# ls -l /dev/net/tun
crwxrwxrwx 1 webadmin root 10, 200 Aug 28 2007 /dev/net/tun


Any idea on how to solve this problem?

Thanks!

Also note:
These commands don't work for me while logged in root on my VPS: http://kb.odin.com/article_130_696_en.html

Might it be the case that my virtuozzo container is not allowed to make use of the tun device because I don't have vzctl access?
