Mike Kolitz has made some good posts about using the February CTP of Vista under Virtual PC / Virtual Server.

First he covers how to install Vista under Virtual PC / Virtual Server (pretty much just the same as it was for the December CTP).

And then he goes on to talk about the really cool trick to getting Glass in a virtual machine - thanks to the hard work of our friends in the remote desktop team (Whoo hoo!).

Cheers,
Ben
