PhpVirtualBox - A web-based front-end to VirtualBox written in PHP

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. phpVirtualBox is designed to allow users to administer VirtualBox in a headless environment - mirroring the VirtualBox GUI through its web interface.
