Download VirtualBox 3.0.10

Sun Microsystems has released the fifth update for VirtualBox version 3.0, which was released at the end of June. This program can be used to install other operating systems on a computer in a virtual environment. That way, different OSes can be used on the same hardware. VirtualBox is available for Windows 2000 and above, Mac OS X, Linux, and Solaris, and can handle a variety of guest operating systems.

VirtualBox is available in two versions. The full version has additional functionality, such as support for USB ports and the remote display protocol, but it is only free for private use and evaluation purposes. This extra functionality is closed source and is therefore missing in the open source version. Version 3.0.10 contains a number of changes that should improve stability and performance and of course make support for Windows 7 better. The changelog also mainly shows bug fixes:

• VMM: guest SMP stability fixes
