Today, the OpenNebula team has released a candidate (RC) of what is to become OpenNebula 2.0. This means that the team is now officially in bug fixing mode, and the repository has been set to feature freeze. Please also note that OpenNebula 2.0 RC 1 is targeted at testers and is not recommended for production environments.
With respect to the previous Beta Release (1.9.80), OpenNebula 2.0 RC1 solves most of the bugs identified during the testing phase and features a new set of decoupled actions from the drivers. This means that with OpenNebula 2.0 it is even easier to tune the operations performed upon specific actions (e.g. shutdown, create, cancel). Also this reduces the number of connections to the cluster nodes so you should also experiment performance improvements in some areas.
We really appreciate the work of the community testing the previous release and giving feedback about issues and bugs. Thank you for helping making a better OpenNebula 2.0!
The OpenNebula Team.
