How big will OpenNebula 2.0 be?

OpenNebula 2.0 is right around the corner, and we were curious to see how much effort has gone into it. As it turns out, nearly double the effort we put into version 1.4, at least measured by the number of lines inserted/deleted/modified in our code repository:

Of course, lines of code are a notoriously imprecise metric, so take the above with a healthy dose of salt. Plus, the above doesn’t account for the additional effort we’ve put into quality assurance, preparing documentation, helping users on IRC and on the mailing list, etc.

In any case, we’re really happy with the 2.0 release cycle, and specially with all the great contributions and feedback we’ve gotten from our community. Looking at the above graph, we’re also amazed at how far OpenNebula has come, from a small technology preview that we initially just ran on a small cluster to a stable and well-tested piece of software capable of wrangling tens of thousands of virtual machines. Another interesting fact about the OpenNebula source code is the number of programming languages and technologies used: C++/C (63.02%), Ruby (21.89%), Java (6.19%), Shell Script (5.79%), Lex & Yacc (2.13%).

So stay tuned… before you know it, you’ll be getting a release announcement from us!

New OpenNebula QA & site!

Last months have been quite busy for the team, a bunch of new features has been added to OpenNebula core as well exciting new components. There has been however a huge amount of effort that may go unnoticed in the upcoming OpenNebula 2.0 release.  As part of this release we also wanted to open our internal QA & testing  procedures to the community… so OpenNebula QA was born!

Testing & QA of a cloud management tool is particularly challenging as it requires to verify the integration of multiple software components, from different hypervisors (Xen, VMware & KVM) and storage architectures (SSH, NFS) to operating systems (Ubuntu and CentOS) and DB backends (MySQL and sqlite). Just check the OpenNebula QA page for a description of the automated test suite we are using, or if you want to check how your favorite Cloud toolkit behaves go to!

OpenNebula Addons: A New Way to Contribute

The OpenNebula Project is happy to announce OpenNebula Addons, a new way to contribute to OpenNebula!. An OpenNebula Addon is an open source, production-ready software extension designed to extend the functionality of OpenNebula, but can not be included in OpenNebula distributions because of license conflicts.  OpenNebula is released under Apache 2.0 license.

The OpenNebula project does endorse these extensions and supports them through the user mailing list. Moreover, the project ensures its full compatibility with current and upcoming releases of OpenNebula. This will allow us to offer new state-of-the-art functionality from companies and organizations that for any reason can not release the software under the Apache license. Participation in OpenNebula Addons requires the contributors to allocate resources to maintain, improve and support the Addon.

OpenNebula 2.0 RC1, ready for testing!

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.
