As I said in my Team System post I was able to play with Virtual Server this weekend.  This is an excellent product.  I've used Virtual PC before but Virtual Server really brings it all together in a nice system. 

For those who don't know, virtual server gives you an easy way to setup and run several virtual computers on one physical box.  It has a very slick web app that allows you to monitor the status of, and configure all the virtual systems running.  It also has a web control that will allow you to control the VPC's from a browser, or if you prefer there's a winapp as well.

The performance seems to be much better to me than what I was doing with Virtual PC. 

Microsoft is offering a free 180 day trial for those who are interested.  I recommend it.
