So let's change the thread and explore yours a bit...

I'd be
interested in where virtual QMTs choke.  Is it IO, proc, mem? 
Maybe too many other guests?

While I only have about 1/2 of
your 500 user choke point, I get very good performance from my VM server
based QMT.  I did have issues before I found some of the tuning
points that I'm documenting in the wiki.  I've been running some sort
of VM in my small business since the days of GSX and in work I have a very
large install of ESX / vSphere.  I do know things like heavily used
databases and the like don't run too well virtualized.  I'd be
interested to see if the QMT limit is something that can be overcome?

I saw your discussion a few days ago with Eric about slow virtual
performance but you said that was with something other than VM?
