VirtualBox 7.0 Alpha 1

VirtualBox is an extremely powerful x86 and AMD64/Intel64-based virtualization solution for both enterprise and home use. This product is targeted at desktop, server and embedded applications It is the only virtualization tool of professional quality that is Open Source Software.

VirtualBox has a variety of features. VirtualBox include:

Modularity. VirtualBox is extremely flexible in its design, with clearly defined internal programming interfaces as well as an interface that is client/server. It is therefore easy to control it using multiple interfaces at the same time. For example, you could start the virtual machine using the typical computer GUI and then control the machine using the command line, or even remotely. VirtualBox comes with a complete Software Development Kit: even while it’s Open Source Software, you do not need to modify the source code to create an entirely new interface to VirtualBox.

Virtual machine descriptions in XML. The settings for virtual machines are completely stored within XML and are not dependent on their local machine. Virtual machine definitions can easily be transferred to different computers.
