VirtualBox is an open source virtualization application that lets you run one operating system inside another. For free. Say, for example you want to check out a new Linux distribution but you don't want to go through the trouble of rebooting your computer. Simple. Just download the disc image for Ubuntu, Fedora, or whatever OS you want to try out, fire up VirtualBox and run create a virtual machine that will let you run the disc image in a window on your desktop.
VirtualBox 2.1 was released last week, and it adds a bunch of new features, including:
- Ability to load 64-bit guest operating systems on host machines running 32-bit operating systems
- Experimental 3D acceleration via OpenGL on 32-bit Windows guest systems
- Easier setup for networking on Windows and Linux host systems
You can find a complete list of new features and bug fixes in the changelog
