phpVirtualBox is an AJAX implementation of the VirtualBox user interface written in PHP. As a modern Web interface, it allows you to access and control remote VirtualBox instances. Much of its verbage and some of its code is based on the (inactive) vboxweb project. It was created for people who prefer not to have to log in to their headless VirtualBox host to administer their virtual machines.
