We have around 150 per host running fine. It obviously depends on your virtualization backend, host, memory, disk, NIC etc. So I'm not sure what you're after. I'm pretty much sure I could easily create something like 10k virtual machines running DOS or something like that on a box with 16GB memory; however, I doubt that it would be useful. On the other hand, this might be a nice test to see how well the libvirt tools handle things.
