What do you do if you are Microsoft, and you realise that people want to run Linux? Attack its credibility? Try to offer what it does well in Windows for free? Advertise Windows better? No, no. The best thing to do is... [drum roll...] support it. Yes, support it. You did hear that correctly. Windows is going to support Linux. And no, that wasn't a flying pig you just saw.
"We've added support for non-Windows virtual machines being hosted on top of our Virtual Server product, including support for Linux. Remember what I said earlier about interoperability? We're really believing that. We know folks are going to want to run Windows systems and Linux systems and other systems together on top of our Virtual Server and Windows. You'll see support for that later in the year." - Comments made by Microsoft CEO at the Microsoft Management Summit in Las Vegas.
