Hi! I just installed openvz on a Ubuntu 14.04 host. I followed this tutorial: https://www.howtoforge.com/installing-and-using-openvz-on-ubuntu-13.04-amd64 Everything seems to be working ok - I already installed an ISPConfig Server in a Container, and tested most functions. Only the Firewall gives me some troubles. When I enable the Firewall over the ISPConfig Interface in the OpenVZ Container, I can't execute apt-get update inside the container for example. There seems to be some problem with the firewall configuration - and I think I already found a first indicator: On my other hosts (debian wheezy) I could just enable the Firewall-capabilities for the container by executing the following on the host: vzctl set xxx --netfilter full --save However when I do that on my ubuntu 14.04 host I get the following: "vzctl: unrecognized option '--netfilter'" I don't find anything on the net regarding this problem. Any ideas where this could come from, and how to fix it?
