VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product 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 General Public License (GPL) version 2. See "About VirtualBox" for an introduction.

Presently, 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.

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 Oracle ensures the product always meets professional quality criteria.

It's portable

Oracle VirtualBox is portable, requires no hardware virtualization, includes guest additions and great hardware support. It also features USB device support, full ACPI support, multiscreen resolutions, and built-in iSCSI support. Support for PXE network boot, multigeneration branched snapshots, remote machine display, extensible RDP authentication, and USB over RDP (Remote Desktop Protocol) is also integrated in Oracle VirtualBox.

Supports 32-bit and 64-bit architectures

At the moment, the program is capable of running only AMD64/Intel64 and x86 architectures. By default, when creating a new virtual machine, you will be able to select the operating system that you plan on virtualizing. Ever since Oracle acquired the Sun Microsystems company, VirtualBox is actively developed by a team of professional engineers who implement new features and functionality with every release.
