EGI Community Forum 2014 Aftermath

Last week was the EGI Community Forum 2014 in Helsinki.

The OpenNebula in Science/HPC workshop was full of interesting talks about OpenNebula clouds for HPC. Thanks to all the speakers for sharing their use case and their feedback.

One of the most commented areas where OpenNebula is still a bit short in features is accounting. Currently people need to parse the accounting output to generate their own reports, but this is precisely something we are already working on. You can try the accounting widget right now in release 4.6.1, which we will continue improving for the next 4.8 version.

On Friday we held the tutorial to build an OCCI-compatible OpenNebula cloud. The attendants were happy to have a more technically oriented session, and all of them were able to build their small cloud in their laptops.

You can download the slides from the workshop here and for the tutorial here.

OpenNebula Conf: Call for Papers Started



After one long year of waiting, finally the second ever OpenNebula Conf opens its Call for Papers again. Everybody who wants to join as a speaker can now propose a talk via the online form at

If you do so, you should definitely reserve a bit of time from December 2nd to 4th and check out flights to Berlin/Germany, because this is when and where cool things will happen.

We are looking forward to your talks and will come back to you by the end of CfP on JulyOpenNebulaConf_CFP_July 15th.


OpenNebula Announces Cloud Technology Day Events in Florida and the Bay Area

The OpenNebula Project has officially announced upcoming TechDay events in Boca Raton, Florida, on June 19th and in Fremont, California, on June 24th. These TechDays are free, full-day events for CIOs, CTOs, VPs of technology, IT directors, cloud architects, sys-admins and devops, featuring a hands-on workshop, as well as presentations from community members and power users.

The event in Boca Raton will be hosted by TransUnion|TLOxp, global leader in information and risk management. The event in Fremont will be hosted by Hyve Solutions, a leader in providing large scale deployments of fully integrated racks of purpose-built data center solutions, and an original Open Compute solutions provider. During this event, attendees will have the chance to participate in the manufacturing plant tour of the Facebook OCP Racks.

“We are happy to host the first Cloud TechDay in USA in our headquarters and present how we are using OpenNebula to deploy our on-premise cloud,”said Armando Escalante, EVP and Chief Technology and Product Officer at TransUnion|TLOxp.

“The Bay Area Cloud TechDay will be an opportunity to discuss how our OCP Open Rack solution can be used in conjunction with OpenNebula to deliver a robust on-premise cloud solution,” said Steve Ichinaga, Senior Vice President and General Manager, Hyve Solutions.

“We are excited to have these leading companies hosting our first community events in the States,” said Ignacio M. Llorente, Director of OpenNebula.

OpenNebula TechDays are an excellent opportunity to meet peers with practical experience building clouds, to find out how leading companies are using OpenNebula, and to learn to design, set-up and operate private clouds.

We look forward to your participation!

Come Meet us at EGI CF 2014

Next week we will be at the EGI Community Forum 2014 in Helsinki, Finland.

On Thursday you will have the chance to gain insight about high performance computing OpenNebula clouds. The workshop, titled “OpenNebula in Science/HPC and Cloud Federation“, will serve as a meeting point for users, operators, and researchers of OpenNebula clouds in Science and HPC. It will also present a unique opportunity for discussion and collaboration with related projects and federated cloud e-infrastructures. This event will focus on:

  • Presenting use cases and deployment experiences
  • Introducing new integrations and developments
  • Discussing limitations and potential enhancements
  • Collaborating with other projects and communities

And on Friday we have prepared a tutorial where you will install an OCCI-compatible OpenNebula cloud in your own laptop. If you are a devop or system administrator interested in a private cloud solution, don’t miss it! No prior knowledge of OpenNebula is required, although you should be familiar with Unix/Linux and virtualization. Even if you are already using OpenNebula, you might be interested in this tutorial since it will showcase the latest cloud provisioning portal introduced in 4.6, and the integration with OCCI.


See you there.
