My name is Ronald Beekelaar. I'm a Microsoft MVP of Virtual Machine Technology, based in Amsterdam. I have my own consultancy firm, and since 2002 I focus on virtualization. At first, this was strictly VMware-oriented, but a few years later this included Microsoft's virtualization products as well.

Since the first public beta of Hyper-V more than a year ago, I have done many presentations about Hyper-V at various events, and talked to a lot of customers about transitioning to Hyper-V. The people I talk to can be divided into two groups: they either have experience with Microsoft Virtual PC and Virtual Server, or they only know the VMware products and are just now looking into Hyper-V. However, for both groups, and despite very different opinions, there are five topics that always come up in discussions. Below is my list of the top-5 things you should know and understand about Hyper-V.
