I'm pretty much with you on that. As of right now Xen isn't quite ready for prime-time yet. For dev and test machines, it might be appropriate, but I'd be hesitant to go with it in a production environment today. That may well change in the future, though like you, I'm a little leery of what seems to be more or less 'pseudo' virtualization.

For the present, VMware rocks in every test we've thrown at it. We'll be doing some major deployments of VMware here within months. It's going to save us a ton of money and time.

We have been using ESX for more than two years now and it is *SWEET*... I would avoid telling any developers machines are virtual they tend to think CPU's and Memory are not an issue with that being the case..

You might be able to help me out here. I've used virtuals for medium server farms (1 app server, 2 app servers in failover, cluster of 2 DB servers, and a few more), and so far I haven't found anything I can't do with MS Virtual Server. But then I don't know if I'm even pushing the envelope to where the differences between MS and VMWare would show.

Any reason to recommend VMWare over Virtual Server except for VMWare running on other host OSs besides Windows?
