The OpenNebula newsletter brings the latest news, advances in the technology, community work and the dissemination efforts carried out by the OpenNebula project this month.

We bring some big news this month! There will be two OpenNebulaConf editions this year, one in US and the other in Europe. The US edition will take place on June 19-20 in Cambridge, Massachusetts, and the european edition will be held in Madrid, Spain, on October 23-24.

Looking for a job in cloud computing? We are still looking for Cloud Developers and a Community Specialist to join our team, check this for more details.


A new maintenance release of OpenNebula 5.2 was released, OpenNebula 5.2.1. This release brings minor improvements in the SDRS clustered vcenter datastores, vlan management and the ec2 driver set. Also, a significant number of bugs have been fixed in 5.2.1.

The team is grooming OpenNebula 5.4. A lot of new features are being worked upon, with a focus on the vCenter integration. Besides all the improvements described in our December newsletter, we’ve decided to introduce a very demanded feature in the vCenter drivers, the ability to create linked clones from OpenNebula. A linked clone is a copy of a virtual machine that shares virtual disks with the parent virtual machine in an ongoing manner. This conserves disk space, and allows multiple virtual machines to use the same software installation. This requires a special VM Template with snapshots included, the import process will allow to change the VM Template to meet this requirement or alternatively clone it and change it so it does. Nice and simple! You can check the full planned change log in the development portal.

New contextualization packages were released as well. new versions of the OpenNebula contextualization packages for Linux (ver. 5.0.3) and Windows (ver. 5.2.0). For Linux, this is mainly a bugfix release with 2 significant improvements. For Windows, this is a very first release, newly distributed as the MSI package.

And last, but by no means least, vOneCloud 2.2 is already out! This release brings the improvements of the latest Excession release to the appliance. vOneCloud is zero intrusive (although it fully manages the life cycle of VMs), try it out without the need to commit to it. If you don’t like it (as strange at that may be!) you can just remove the appliance.


This last month we announced officially the OpenNebula Champion Program. Champions are passionate volunteers who work to connect, teach and spread OpenNebula. They represent OpenNebula and help to teach and spread OpenNebula, throughout the world.

vOneCloud is solving a big problem in the self provision of VMware resources. An excellent article in The Register beautifully lays out the simplicity it introduces in a sometimes overbloated paradigm. Being named as one of the five open source tools admins need to know is an honor.

It is a real luxury to count with excellent members (and Champions!) in our community. This extra testing makes OpenNebula more robust and more production ready, and we deeply appreciate that. We also get to receive outstanding contributions like this one, enhancing the virtual router with Load Balancing features. Amazing, big thanks from the team!

And keeping the ecosystem up to date is not small task either, so this update of the Nagios Probes for Monitoring OpenNebula and OCCI is good news.


If attending the OpenNebulaConf is giving you trouble (because you cannot miss it!), then make it double.
