It's pretty simple. What OpenVZ kernel does it creates a container and
runs /sbin/init inside it. What goes next is up to that particular
/sbin/init. If you need to run an app let /sbin/init run just it, or let
this app be /sbin/init (but bear in mind there will be no child reaper
as in usual linux system so you might need to take some extra care about
zombie processes).
