The following items were fixed and/or added: VirtualBox 4.3.18 is a maintenance release. Virtual machine definitions can therefore easily be ported to other computers. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. 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. 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 has an extremely modular design with well-defined internal programming interfaces and a client/server design.

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 and AMD64/Intel64 virtualization product for enterprise as well as home use.
