VirtualBox

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). See "About VirtualBox" for an introduction.



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. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while Sun ensures the product always meets professional quality criteria.

The screenshots below show several impressions while running VirtualBox on Linux, Windows, Mac OS X and Solaris platforms:

	VirtualBox for FreeBSD. This screenshot shows a first version running Ubuntu. NAT networking works.
	VirtualBox for FreeBSD. This screenshot shows a first version capable of running Windows.
	VirtualBox for Mac OS X. One virtual machine is running in seamless mode on Leopard. Note the realtime preview of the virtual machine in the dock.
	VirtualBox for Mac OS X, currently in beta test. Two virtual machines are visible: one with Windows Vista, another with Gentoo Linux.
	Creating a new, empty VM for installing Windows Vista.
	The new VM in the VirtualBox main window. Note that an ISO file (containing the Vista setup CD) has been mounted as the VM's CD-ROM drive.
	After starting the VM, it boots off the virtual CD-ROM (the ISO file with the Vista setup), and Vista Setup starts up.
	Vista is installing into the virtual hard drive.
	Vista install complete: the log-on screen.
	Compiling VirtualBox on Ubuntu Edgy Eft in VirtualBox on Windows XP.
	Details of a snapshot performed after Vista installation. We can revert the virtual machine to this snapshot at a later time.
	Damn Small Linux 2.0 works damn well in VirtualBox!
	The Virtual Disk Manager allows you to work with VM images.
	VirtualBox in Vista inside VirtualBox on XP? Perhaps some day...
	A community-based effort is underway to port VirtualBox to OS/2 hosts. This screenshot shows a first alpha version.
