PhpVirtualBox –An open source, 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. phpVirtualBox was designed to allow users to administer VirtualBox in a headless environment – mirroring the VirtualBox GUI through its web interface.
