SUN has a free virtualization platform called SUN VirtualBox, so whats new in that you might wander – many companies offer virtualization these days!? The cool thing here is the word “Free” and lets add “Fast” to make it interesting, the solution is not only free it’s also fast and even somewhat compatible with Microsofts virtual pc format (it can import a .VHD file and start it without much hassle).
So if you are into a free, fast and quite well working Virtualization solution then take a look at “VirtualBox” from SUN.
