Download VirtualBox 2.2.2

Sun Microsystems today released version 2.2.2 of VirtualBox. This program can be used to install another operating system in a virtual environment. This makes it possible, for example, to test applications in multiple environments, without having to purchase specific hardware. VirtualBox is available for Windows 2000 and above, Mac OS X, Linux, and Solaris, and can handle a variety of guest operating systems.

The software is available in two versions. The full version has more functionality, such as support for USB ports and the remote display protocol, but is only free for private use and evaluation purposes. This extra functionality is closed source and is missing in the other version, the open source version. Version 2.2.2 is the successor of version 2.2.0, which includes support for the Open Virtualization Format, USB support on OpenSolaris and OpenGL for Linux. This release is a maintenace release and mainly fixes issues:
