VirtualBox application is a family of powerful x86 virtualization products for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU Public License (GPL). See "About VirtualBox" for an introduction; see "InnoTek" for more about our company.

Presently, VirtualBox runs on Windows and Linux 32-bit hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista), DOS/Windows 3.x, Linux (2.4 and 2.6), and OpenBSD.

VirtualBox is being actively developed with frequent releases and has an ever growing list of features, supported guest operating systems and platforms it runs on. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while InnoTek ensures the product always meets professional quality criteria.

Requirements:

· You will need to install some additional libraries on your Linux system in order to run VirtualBox - in particular, you will need libxalan-c, libxerces-c and version 5 of libstdc++. How to install these will depend on the Linux distribution you are using.
