OMG!! running multiple daemons??? Wow why didn't I think of that?? I *love* OS overhead on misbehaving hardware emulation because it is what "the industry" prescribes. Don't forget the 50% hit on I/O speed because that is what every enterprise needs. And lets not forget the windows only license servers combined with "management" tools that also run only on windows and IE. Virtualization is sooooo awesome.
