VirtualBox is a virtualization tool for both enterprise and home use, that allows you to create virtual machines. This Open Source application is feature rich and boasts high performance, enabling you to run multiple guest operating systems that include Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (2.4 and 2.6), and OpenBSD.

Everyone is encouraged to contribute to VirtualBox and that will lead to more features, an increase in supported guest operating systems and platforms.
