if you haven't tried OpenStack with LXC yet

[Thomas Leonard]

Hi Brian,

Sorry, I wasn't very clear there: it was OpenVPN that I initially installed 
in a VM (not OpenStack itself).

I have been using Juju with local LXC for testing, but we needed a proper 
server-based solution where we could deploy services for others to use. 
Local LXC deployments aren't exposed to the public network and they don't 
come back if the machine is rebooted, so they're not useful for production 
at the moment.

It's interesting that OpenStack can be configured to use LXC. However, I 
went with the default (KVM) and I didn't have any problems with that part.

Thanks,
