In July, Microsoft contributed over 20,000 lines of source code to the Linux kernel under GPL V2. Linus Torvalds provided assessment: “I agree that it's driven by selfish reasons, but that's how all open source code gets written! We all "scratch our own itches". It's why I started Linux, it's why I started git, and it's why I am still involved. It's the reason for everybody to end up in open source, to some degree. So complaining about the fact that Microsoft picked a selfish area to work on’s just silly. Of course they picked an area that helps them. That's the point of open source - the ability to make the code better for your particular needs, whoever the 'your' in question happens to be.[…]”. And Jason Perlow was so intrigued by the new capabilities in Windows Server 2008 R2 Hyper-V and Microsoft Hyper-V Server 2008 R2 that he installed various Linux distros (CentOS, Scientific Linux, OpenSUSE) atop Hyper-V R2. This documented here with step-by-step instructions for each distro!
