I use LXC in production for all my server services (web hosting, dns servers, internal dhcp, directory services, ...) and for the Edubuntu WebLive VDI service (hundred of desktop installations running under LXC). All in all, that's somewhere around 300-400 containers I'm managing in production, without any problem so far. This is all running on Ubuntu 12.04 LTS with apparmor on both host and containers. Using apparmor fixes all the security concerns that have been highlighted so far with containers and Ubuntu ships the latest upstream LXC and has a container-aware userspace that doesn't require any kind of hack to work in containers. You mention you're using Centos, I'd suggest that's really your problem as nobody is working on LXC on Centos so the distribution probably wasn't made container aware, we don't actually have a maintained template for it and it's likely that some other bits of LXC plain don't work because nobody tested it on centos. We recently got some contributions for LXC support on Oracle Linux which as far as I know is pretty close to RHEL6/CentOS, so maybe that work will lead to a better experience on CentOS, but that may take some time. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
