I followed the instructions located here: http://wiki.openvz.org/Quick_installation

I followed the instructions exactly down to the end of the section entitled "Rebooting into OpenVZ kernel".

Since i've rebooted I can't seem to access the server on my network via sshd, I have physical access so its not a problem to fix, however I don't know what to fix.

I am running CentOS.

Although this is a test situation I hope to install OpenVZ on a machine at a remote location and therefore need to ask how this can be done without physical access.

Any help would be greatly appreciated!

It seems something has changed my firewall/iptables settings as if i do:

service iptables stop

I'm able to ssh into it again!

I then used:

system-config-securitylevel

From there I realised that eth0 was not "trusted", so I enabled that and I can now ssh in again.

The question is now, how do I ENSURE this will not happen if I do it on a machine at a remote location, otherwise this will cost me to rectify.

Thanks.
