I was studying for my RedHat RHCE, and wanted to do some stuff at home, so I downloaded the VMWare Server 2.0 beta. I can't say I was impressed at all with it. The 'neat' thing is that the server console is all now web-based, but, of course, that comes with a price. Tomcat is used as their middleware, and was taking up 3-400 MB on my machine, just to do the management of the box. Talk about overhead.
