Intel has recently released their new “Sandy Bridge” processors which is the second generation of the Core i3/i5/i7 processors. Most of these new processors hitting the market with the first wave of product released are designed for notebooks and a few for desktops with server processors on the way. An easy way to identify the new Sandy Bridge processors is that the processor models are 4 digits. For example, you’ll see processors such as the i7-2600k or i5-2500k and so on. There are a number of good articles on these new processors (like this) so take a look if you’re interested in what’s new.

I’m raising this topic because I want you to be aware of an issue with both Windows Server 2008 R2 Hyper-V and Microsoft Hyper-V Server 2008 R2 and the new Sandy Bridge processors and provide the solutions.

Issue: When you attempt to start a VM running on a system with a Sandy Bridge processor, the virtual machine will not start. If you go to the Event Viewer you will see an error that states: “<VM Name> could not initialize” error.
