VirtualBox is a general-purpose full virtualizer for hardware. Targeted at server, desktop and embedded use, VirtualBox is now the only professional-quality virtualization solution that is also Open Source Software. 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.
