VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. VirtualBox is a powerful x86 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. Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris 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), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, 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.

Some of the features of VirtualBox are:
• Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full 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 descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
• Guest Additions for Windows and Linux. VirtualBox has special software that can be installed inside Windows and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window).
• Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.

A number of extra features are available with the full VirtualBox release only (see the "Editions" page for details):
• Virtual USB Controllers. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host.
• Remote Desktop Protocol. Unlike any other virtualization software, VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data.
• USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in.

Changes in VirtualBox 4.1.6 (released 2011-11-04):
* VRDP: fixed screen corruption
* NAT: the interface stopped working after a lot of failed ICMP requests (bug #9371)
* E1000: fixed rare Windows 7 guest hangs, either at boot time or when reconfiguring the network card in unusual setups (bug #6223)
* ATA: fixed a possible crash during ATAPI passthrough with certain guests
* ATA: improved compatibility with ancient Linux kernels
* Main: fixed incorrect framebuffer information after leaving the fullscreen mode with X11 guests, this lead to a scrambled preview window in the GUI for example
* Mac OS X hosts: fixed the problem with duplicate packets when bridged to a wireless interface (bug #9648)
* Linux hosts: fix for 3D support on Fedora 15 (bug #9799)
* Linux hosts: don't call del_timer_sync from an interrupt context (Fedora bug report 746331)
* Windows Vista and 7 guests: more WDDM fixes
* Linux Additions: fixed kernel module compilation failure on Redhat Enterprise Linux 4 (bug #9709)
* Linux Additions: install the DRI driver correctly on Ubuntu 11.10 guests
* Solaris Additions: added read-only mmap support for shared folders
* Solaris Additions: added directory, file mode and mask options for shared folders
* Windows Additions: implemented faster detection of logged-in guest users and stale sessions
* X.Org Additions: fixed graphical corruption when switching to a virtual terminal (bug #9490)
