I think the overhead on the processor is from 1 to 4% when virtualbox has
nothing to do.
We don't have a big pool of users of POVB, but I have had no complaints.


Our main pool is a dual boot one that we auto switch from Windows to
Linux/Condor over night and weekends. This works well for us, but
obviously the pool we can provide during normal working hours is quite
small (200 cores).
