How has that VMotion stuff worked for you? I saw a demo of a migration of a fully operational database server from one machine to another. It was one of the most impressive tech demos I've ever seen. It takes a lot to make me go "wow", and that did it. I'm interested in how well it actually works in the real world.
We have had no problems with it, nothing impressive as moving an online DB. But we have moved around live webservers, fileservers, domain controllers and the like with no downtime..
