Download VirtualBox

VirtualBox is a powerful x86 and AMD64 / Intel64 virtualization product for both corporate and home use. VirtualBox is not only a very feature-rich and high-performance product for enterprise customers, but also the only professional solution freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2. See “About VirtualBox” for an introduction.

Currently, VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10) , DOS / Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS / 2, and OpenBSD.

Modularity.

VirtualBox has a very modular design with a well defined internal programming interface and a client / server design. This makes it easy to control it from multiple interfaces at once: for example, you can run a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or perhaps remotely. VirtualBox also comes with a complete Software Development Kit: even though it is Open Source Software, you don’t have to hack the source to write a new interface for VirtualBox.

Virtual machine description in XML.

The virtual machine configuration settings are stored entirely in XML and are independent of the local machine. Therefore, the virtual machine definition can easily be transferred to other computers.

Guest Additions for Windows, Linux and Solaris.

VirtualBox has special software that can be installed inside Windows, Linux and Solaris virtual machines to increase performance and make integration much smoother. Among the features this Guest Addition provides are integration of the mouse pointer and arbitrary screen solutions (eg by resizing the guest window). There is also a guest addition for OS / 2 with slightly reduced functionality.

Shared folders.

Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox makes it possible to declare specific host directories as “shared folders”, which can then be accessed from within the virtual machine.

VirtualBox is being actively developed with frequent releases and has a growing list of features, supports both guest operating systems and the platforms they run on. VirtualBox is a community effort supported by a dedicated company: everyone is encouraged to contribute while Oracle ensures products always meet criteria of professional quality.
