Not as such, no, but: OpenVZ has a single scheduler across all threads
/ processes in all VEs. So, if you imagine the scheduler as working
on a single system with all those tasks the normal rules of process
scheduling apply.
Which means that if you set your higher priority stuff to a high nice
level, or real-time priority, it will take precedence over another VE
that runs lower priority stuff.
Finally, if you assign appropriate CPU shares to the VEs you can
ensure that they will get all the time divided appropriately at a high
level.

Daniel
PS: Native Linux doesn't support this either. :)
