I'm not currently using #, though both it and # are on my list (as well as manipulating LXC directly) of things to explore.

I also considered #, but took a look at the installation instructions and found that the instructions are designed to give you # (the paid version, perhaps better called ClosedVZ or PaidVZ). I'm sure I can figure out how to get the desired configuration, but I thought that was a little deceptive. It does not inspire much hope that they won't try other tricks to prevent people from running the FLOSS version, so they'll pay for it.

I'm not against paying for software, but I am against using manipulation to push people into paying.
