Don't forget though that with security becoming a rising concern and
problem, you open a bigger vunerability buy running on this model. If
the host system is compromised (from outside or via one of the virtual
machines), all of the virtual machines become compromised. If those 100
virtual machines were independant, if one is breached, the other 99 are
still secure.
Just my something which popped up in my head while re-reading this thread.
