|VirtualBox is a general-purpose
cross-platform virtualization application by
Oracle, for x86
What does that mean? For one thing, it installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac, Linux or Solaris operating systems. Secondly, it extends the capabilities of your existing computer so that it can run multiple operating systems (inside multiple virtual machines) at the same time. This way, you can run software written for one operating system on another (for example, Windows software on Linux or a Mac) without having to reboot to use it.
There are versions of VirtualBox for Windows, Mac OS X, Linux and Solaris hosts. VirtualBox runs on a large number of 32-bit and 64-bit host operating systems. You can install and run as many virtual machines as you like -- the only practical limits are disk space and memory.
VirtualBox is deceptively simple yet also very powerful.
VirtualBox comes in many different packages, and installation depends on your host operating system.
The base package consists of all open-source components and is licensed under the GNU General Public License V2.
