Virtualisation has become so popular that it is even available as an integrated option in Windows 7. Most people prefer to turn to a dedicated virtualisation tool, however, and VirtualBox has proved to be one of the most popular and impressively powerful programs available. Version 4.0.6 of the app has just been released, bringing with it a sizeable list of bug fixes.

There have been major improvements in the stability of the app, helping to provide a far more user-friendly virtualisation experience. Memory leaks have also been plugged and the option to store snapshots in the same directory as virtual machines has been added.

A number of networking issues have been addressed in VirtualBox 4.0.6 and problems with sleep mode and system resumption have also been fixed. Linux users can now take full advantage of more recent kernels thanks to improved support, while Mac and Windows users will find that interface quirks and unexpected hangs have also been eliminated.

VirtualBox is available for Windows, Linux and Mac, and can be used to run virtualised copies of Windows , DOS, Linux, Solaris and OpenSolaris, OS/2, and OpenBSD. To find out more and to download a free copy of the application, pay a visit to the VirtualBox review page.
