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).
