This monthly newsletter features the latest developments in the OpenNebula project, highlights from the community and the dissemination efforts carried out in the project this past month.

As you may know, the first ever US edition of the OpenNebulaConf will take place on June 19-20 in Cambridge, Massachusetts. Check out the keynotes by Akamai and Harvard, and reserve your seat in Boston! The complete agenda will be out in a few days.


OpenNebula 5.4 is going to place a new mark in cloud management excellence. A wealth of new features are being now stabilized, and that is what’s keeping the development team busy these days. As you know, the vCenter driver is getting a major revamp in terms of storage and network management (check out more details in this article). These new features will enhance OpenNebula provisioning model over vCenter based infrastructures, increasing the already wide range of use cases that can be implemented with your favourite Cloud Management Platform.

Let us lay down another set of features that are recent arrivals to the release:

  • Enhanced VM history logging
  • Image persistency selection
  • Modifiable semantics for permissions
  • IPv6 non SLAAC Address Ranges

.. and there will be more before the beta is released by the end of the month!

The team is particularly excited about the scheduler new ability of creating VM Groups with roles in which you can define affinity/anti affinity between VMs and virtualization hosts. This way OpenNebula supports use cases where VMs needs to be placed together for license issues, network performance reasons (place the DB and server together for instance), computational reasons or a wide range of other use cases. As usual, a picture speaks a thousand words. This feature has been sponsored by BlackBerry in the context of the Fund a Feature program.


Check out in the project’s development portal all the things we are still working on.


New advancements in the community are always a pleasure to review, it is the time to notice that the OpenNebula community is as supporting and caring as always. Newcomers surely feel the warmth of the support forum, where users, developers and integrators give their best to aid users with questions and problems about OpenNebula and really interesting use cases. We’d like to show this spirit with this thread, where people show their best to help use OpenNebula with resources from a hosting company. Way to go!

It is always a pleasure learning how OpenNebula is used in a wide range of industry niches and institutions, like it use in the Turin INFN science cloud. Building reliable and useful, real world clouds is our main goal all along!.

An excellent post describing the hybrid model and why is interesting for enterprises and institutions is featured in the OpenNebula blog this month. The hybrid model in OpenNebula is a native capability, which can leverage the traditional cloud promise: infrastructure elasticity.

The idea of combining resources of public cloud providers with private depending on the terms of execution, the need of more resources, an extra protection of the data, more or less security in services with sensitive information, etc. are some of the capabilities that this model has to answer.

NodeWeavers shows us how to create an OpenNebula cloud in record time. Whoa! Their portable cloud looks nifty indeed!

We are very proud to announce that OpenNebula is a key components of the recently announced Telefonica rendering of the CORD framework (R-Cord)! We believe this is an important step to develop resilient clouds to deliver residentials phone and cloud services to end users. The architecture of the solution can be found here and it is a good read for all people interested in cloud and NFVs.


The OpenNebulaConf is the perfect spot to meet up with other cloud professionals and take the temperature of the cloud computing field (check the material of 2016 edition if you want to know more). The first US edition of the OpenNebulaConf is happening this 2017, as one of 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.

June is approaching fast! Have your seat prepared in Boston? If you are interested listening at what Harvard and Akamai have to say about their use of OpenNebula in their production infrastructures, then you need to move quickly and make sure that you get a place!

This past month members of the OpenNebula team went to Prague, and did the first test on the field of the new tutorial format where the cloud is deployed within a public cloud provider. This helped a lot for people with Windows or 32 bit laptops.


The next TechDay will take place in Madrid, hosted by Telefonica,and the speakers line up look promising. Stay tuned if you are in the area since you may be interested in attending the hands-on and the talks.

The OpenNebula team is going to feature a booth in both VMworlds this year. If you are going to attend, do not forget to come by the OpenNebula booth to see a live demo of the latest stable version of your favourite CMP:

  • VMworld 2017 US, August 27-31, Las Vegas, Mandalay Bay Hotel & Convention Center
  • VMworld 2017 Europe, September 11-14, Barcelona, Fira Gran Via

Also, check out the list of official training from OpenNebula Systems for this year. If you are new to OpenNebula, or want to improve you knowledge with an in-depth OpenNebula admin course, those are the dates and locations you need to keep in mind.

Remember that you can see slides and resources from past events in our Events page. We have also created a Slideshare account where you can see the slides from some of our recent presentations.
