OpenNebula 2.2 Released

OpenNebula 2.2 adds new features to help production Clouds and improves the user experience with the new graphical interface Sunstone.

The OpenNebula Project announced today the general availability of OpenNebula 2.2 for download. OpenNebula is the open-source reference technology to deploy enterprise-class infrastructure clouds, used by thousands of organizations across multiple industries. OpenNebula 2.2 is the seventh major release of the project and with it, it continues to fulfill the promise of building a state-of-the-art open source toolkit that also addresses the scalability, flexibility and security requirements of large-scale production systems.

“With OpenNebula 2.2 we continue to make OpenNebula the open-source choice to deploy an Infrastructure Cloud”, said Ignacio M. Llorente, Project Director at “We are adding new features to strength the production-ready nature of OpenNebula, making it the most proven, powerful an interoperable technology in the cloud arena”.

OpenNebula 2.2 extends the fault-tolerance features of the toolkit and includes out-of-the-box integration with data-center’s monitoring systems.

“We are also very excited with Sunstone, the brand new web application. Since the start of the project we have received a lot of requests from the community to include a graphical interface, and now OpenNebula 2.2 makes a reality this long awaited feature”, said Ruben S. Montero, Chief Architect at “Sunstone leverages the functionality of previous interfaces and allows you to manage and administer your cloud in a graphical manner, with lots of eye candy.”

OpenNebula is the result of many years of research and development in close collaboration with leading IT organizations. Many of its innovative features have been developed to support business use cases from leading companies in RESERVOIR, flagship of the EU-funded projects in cloud computing. This last version also brings features developed in other groundbreaking projects, such as StratusLab and BonFIRE.

The OpenNebula project would like to thank the community for their effort and valuable contributions that have made this release possible; the European Commission for founding part of the developments of this release; and our private sponsor, C12G Labs, for supporting the community and software contributions.
