sorry, but this is the wrong question. Using virtual machines makes some things more complicated, but it also enables simplification of other things. Eg. I use some virtual machines for things I need only occasionally where using physical machines would just be a great waste, and I'm aware of other outfits who use virtual machines to avoid having to tend to a zoo of underutilized servers, but where putting everything into one server was impractical, too. Now they have a few servers running this stuff as virtual machines, while at the same time providing automatic failover in case one of the physical "carrier" machines goes down. So, these guys now have better overall utilization of (much) better hardware, plus increased reliability, plus reduced cost because their hosts and the management suite on top of that provides them with much better facilities and flexibility than having said zoo of individual tin boxes could provide.
