The program was created by Innotek using the source code Qemu. The first publicly available version of VirtualBox has appeared on Jan. 15, 2007. In February 2008 Innotek has been bought by Sun Microsystems, the model distribution VirtualBox with no change.

VirtualBox - a program for creating virtual machines. By allocating resources to the computer creates a separate virtual system with its own resources and, most importantly, with its own operating system. For example, on a computer with the Windows operating system you are in the two accounts can create a virtual system, under which select certain resources and install Linux. Or, conversely, to a computer running Linux to install Windows. As the main operating system, VirtualBox supports Windows, Linux, Mac OS and Solaris. In the role as a virtual system can perform virtually all popular operating systems. The program supports the installation of the operating system either from CD or from the image file. It is very simple and will not cause serious difficulties even for novice. It remains to add that the program is absolutely free and is distributed through open source.

Key features:

Cross-platform
Modularity
Support USB 2.0, when the device host machines are available for guest OS (only in proprietary versions)
64-bit guest operating systems [1] (since version 2.0), even on 32-bit host systems [2] (since version 2.1, for it must support virtualization technology processor)
SMP support on the side of guest system (starting with version 3.0, for this must support virtualization technology processor)
Built-in RDP-server and client support for USB-devices on top of protocol RDP (only in proprietary versions)
Experimental support for hardware 3D-acceleration (OpenGL, DirectX using code wine)
Support for a hard disk VMDK (VMware) and VHD (Microsoft Virtual PC), including snapshots (beginning with version 2.1 [3])
Support for iSCSI (only in proprietary versions)
Virtualization audio
Support for different types of networking (NAT, Host Networking via Bridged, Internal)
Support the chain of saved virtual machine states (snapshots), which can be rolled back from any state guest system
Support for Shared Folders for easy sharing of files between the host and guest systems
Support the integration of desktops (seamless mode) host and guest OS
It is possible to choose the interface language (supported and Russian interface).

Unattended - this program is installed automatically ie you do not need to enter keys are not and do not use other methods of registration (patches, cracks, etc.) program, with Unattended installation does not have to constantly continue to reap the program itself will do everything for vas.Posle installation was fully prepared work.
