Wow vps is highly experimental and at it's core, it uses "VIMAGE" which is also highly experimental and unsupported. It's hot server swap ability is only achievable because of vps integration into FreeBSD kernel making it require a unique vps version for each release of FreeBSD. To me, I see vps as a wrapper around "VIMAGE" intended to simplify the difficult network configuration setup associated with using "VIMAGE" in a jail environment. Other FreeBSD services need to be made "VIMAGE" aware, like firewalls IPF, PF which dump if run on the host with "VIMAGE" compiled into the kernel and ipfw which does not dump but has very limited functionality. In this thread I read about references to ezjail. It's based on the hosts rc.d boot scripts which in release 10.0 is being depreciated in favor of jail(8). As the number of running jails increase the difficultly of managing them also increases. ezjail has no provisions to address this problem. qjail on the other hand is designed from the ground floor to simplify the administration of large scale jail environments [1 to 2000+ jails]. It's built around jail(8) and has option to build vnet/vimage jails. You should review both qjail and ezjail and choose based on which one best meets your unique usage requirements.
