Actually you can get virtualization completely free these days. From VMWare, we have VMWare Player, which is based on VMWare Workstation, and VMWare Server, which is based on VMWare GSX Server. Microsoft recently announced that Microsoft Virtual Server 2005 R2 is now free. Microsoft is even supporting Linux with Virtual Server, including virtual machine additions for Linux. Microsoft has also loosened up its licensing policy when it comes to virtualization technologies. So whether you prefer VMWare’s or Microsoft’s virtualization products, things just got a whole lot cheaper!
