You are only considering the security values of OpenVZ. Where I work,
OpenVZ and Linux-vserver are used for their ability to cleanly
separate processes. Security-wise, we could get the same effect just
by running the processes as separate users, but management-wise it is
so much easier to give them a completely separate environment.
OpenVZ's network virtualization enables us to do things which are
completely impossible with both the vanilla kernel and Xen -- e.g.
hundreds of virtual routers, with their own routing daemons.

Policy routing just doesn't cut it; it's cumbersome to set up, limited
to 256 tables, and routing daemons generally can't handle it well, if
at all.
