Before that we ran openvz. And before that, we ran vserver.
If you have a minute and can share, I'd love to hear why you switched away from vserver (and then openvz but especially vserver). Or maybe you have those transitions written up somewhere?
Sure - for openvz it was more powerful resource accounting and limits (this is back in 2008). I think there was extra goodness around networking, but honestly I can't remember. Mostly we were trying to figure out which project would find its way into mainstream, so we could standardize on that. vserver had been around forever and somehow never made it in, so OpenVZ looked like our best bet. Of course we turned out to be wrong :)
