Virtualisation continues to be a buzzword. The idea isn’t new in itself; IBM mainframes have always had to have a hypervisor. It’s in the news now because even simple desktops can now act as virtual machine hosts. A lot of possibilities have opened up as a result. Let’s take a brief tour of what virtualisation means, in its classic sense, and look at why open source virtualisation is going to win.
KVM, the Kernel Virtual Machine monitor, was announced in late 2006, and was merged in Linus’ tree in December the same year. It has very quickly gained wide acceptance and adoption for being the most promising and capable virtualisation strategy on Linux. Though a very young project, new features are being added at a very brisk pace thanks to the interest taken by several companies and developers across the globe.
