Open Source Virtualization Software

Sunday May 27, 2007

VirtualBox is a general-purpose Enterprise and Open Source virtualizer for x86 hardware written by the German software house innotek GmbH. It implements full virtualization and lets you run other operating system on your PC without requiring any changes. This is done by running in a special environment called a virtual machine by intercepting access to hardware components. Most of the code running on this virtual machine is run at near native speeds so long as it is targetted for the same hardware.

This allows multiple operating systems to be run without a reboot. The Open Source version of VirtualBox is written in C++ and a link to it has been added to the C++ Code library. Note this version currently lacks the Remote Desktop Protocol server and USB Support of the Closed Source version though these may eventually end up in the Open Source version. The open source version is licensed under the GNU GPL.

Back soon!
