OpenNebula 2.0 RC 1 (1.9.90)
23th September, 2010. The OpenNebula team has released the first release candidate version of what is to become OpenNebula 2.0. OpenNebula 2.0 RC 1 is targeted at testers and users that would like to peep at what's coming to their clouds!. OpenNebula 2.0 RC includes a significant amount of changes and new features in many areas, bringing the most flexible, scalable and feature rich Cloud Toolkit to the Free Software community. OpenNebula 2.0 is the result of a close collaboration with our user community to address their scalability, flexibility and security requirements in large-scale production systems.
With respect to the previous Beta Release (1.9.80), the OpenNebula 2.0 RC1 features a new set of decoupled actions from the drivers. This means that wit 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 wokernodes so you should also experiment performance improvements in some areas.
This new release will break compatibility with OpenNebula 1.4 (at DB and API levels), therefore we've decided to follow a larger release cycle to make a smooth transition period, and also to stabilize API's and internal data models for the new components.
Here you can find the complete list of changes
Since OpenNebula 2.0 Beta a new DB schema has been introduced. The new schema is not compatible with the schema present in OpenNebula 1.4. Host, Networks or Virtual Machines defined in OpenNebula 1.4 installs will not longer work with this release.
OpenNebula 2.0 includes new API calls and methods. However there have been no changes in those API calls already supported in OpenNebula 1.4. Applications using OCA (Ruby and Java bindings) are expected to work with OpenNebula 2.0.
The complete source tree for OpenNebula can be freely downloaded here. The compilation has been tested on the main linux distributions, please check the platform notes for more information.
Also binary packages for Ubuntu 10.04, CentOS 5.5, Debian 5.0.6 and RHEL 5.5 are available for download.
