OpenNebula 2.2 RC1 adds:

• General stability, and performance improvements
• See the complete changelist from the previous betas

As well as these features from previous OpenNebula 2.2 Betas:

• Sunstone. A web application to manage and administer a cloud. This is the first public release of this new component, which levels the functionality of the command line interface tools. Next releases of OpenNebula will improve Sunstone to include more features, like user profiles or graphical representations of the cloud status.
• Fault Tolerance (FT). OpenNebula FT has been improved in this release to automatically trigger recover actions when a physical host (or VM) fails.
• Ganglia. Ganglia is a wide-spread monitoring system. Large deployments may benefit from the scalability of Ganglia and use it as the monitoring source for physical hosts and VMs.
• Image support in OCCI. The OCCI cloud interface it is now integrated with the OpenNebula image repository and exposes most of its functionality.
• Virtual Networks, have been improved to allow its dynamic modification without the need of re-create them.

OpenNebula is released under the Apache 2 open source license. The complete source tree and binary packages for OpenNebula can be downloaded here.
