Xen Orchestra is an open-source project that gives a web-interface to the Xen virtualization platform via XCP and its API (XAPI).
The Xen Orchestra project was conceived back in 2009 but then abandoned due to time constraints and only recently restarted. Olivier Lambert of the project wrote an email to Phoronix with details of this project revival. "The project was born in 2009, but dead since, due to a lack of time for myself and my friend. But in the end of 2012, we decide to reboot the project for XCP/XAPI, supported by our own company. There is no other Open source living project for this, so we are 'expected' by Citrix themselves: they gave us the opportunity to talk about the project during the FOSDEM."
The goals of Xen Orchestra are to provide a simple and nice interface for managing virtual machines and XCP servers, displaying the global state of the virtualization infrastructure, and expose nice functionalities of XAPI to the web interface.
