The OpenNebula Project is proud to announce the first agenda and line-up of speakers for the fifth OpenNebula Conference to be held in Cambridge, MA from the 19 to the 20 of June 2017. Guided by your feedback from previous edition, we included more educational and community sessions to learn and do networking.


The agenda includes four keynote speakers:

Educational Sessions 

This year we will have two pre-conference tutorials:

We have also increased the number of educational contents with presentations from the OpenNebula team showing and demoing some of the most demanded features and latest integrations.

Community Sessions

We had a big response to the call for presentations. Thanks for submitting a talk proposal!. Although all submissions were of very high quality and merit, because this year we increased the educational contents we only have space for a few community presentations. Jordi Guijarro from CSUC,  Roy Keene from Knight Point and Hayley Swimelar from LINBIT will discuss their experiences and integrations with OpenNebula.

We will also have two Meet the Experts sessions providing an informal atmosphere where delegates can interact with experts who will give their undivided attention for knowledge, insight and networking; and a session for 5-minute lightning talksIf you would like to talk in these sessions, please contact us!

Besides its amazing talks, there are multiple goodies packed with the OpenNebulaConf registration. You are still in time for getting a good price deal for tickets. There is a 20% discount until May 12nd.


We are looking forward to welcoming you personally in Boston!


OpenNebula Newsletter – March 2017

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.

Hybrid Clouds: Dancing with Virtual Machines

Today, the model of hybrid cloud comes under the eyes of a lot of organizations. 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. The case of CSUC, acting as Opennebula powered cloud provider and at the same time as user of external IaaS and PaaS services, is analyzed sharing its first experiences in the way to archive a real multicloud architecture.


Figure 1- The Hybrid Cloud, acts as a slicing bridge.

The majority of organizations have not been born in the “cloud”, situation that produces a lot of cases where the cloud resources have to interact or to be connected to traditional systems and applications with some criticality and usually are situated in its own dependencies. This kind of architecture is the most usual, where the main keys for its success go through to be aware about things like the integration capabilities or the impact in the organization roles where could exist different interpretation of the same concept.

For a solutions designer the model has to offer flexibility, speed and capacity. In the case of the infrastructure team it’s easy to think that more “different things” have to be managed. The business development staff will ask if it will be more expensive and which is the value that the hybrid model will contribute.

From the IT infrastructure perspective, when a public cloud provider is selected/procured, a good approach to start with in the adoption of hybrid cloud model is to focus in these first three challenges.

  • Networking: to extend your network layers with capable “dedicated” circuits provision with bandwidth control outside and inside public cloud provider(s).
  • Management: to consolidate a truly global infrastructure management platform through a cloud orchestrator and its cloud bursting capabilities.
  • Security: to extend to public cloud provider current security layers (platforms, tools, policies,…) under the current organizations umbrella.

Definitely, the model or architecture to implement will be different depending on each case where the applications/services have a lot to say and have to be listened. The pure reality is that nowadays almost all the organizations work in two different speeds and this is something that the technology departments have to work with. Some very changing environments like web and mobile applications and other more robust systems associated to critical processes with high levels of stability and security. A real cloud hybrid model should support the combination of this two speed ecosystems maintaining its specific dependences and needs.

The CSUC use case: driving to a hybrid cloud architecture

CSUC, in these last two years has worked in these challenges with some actions that are transforming roles, the management models at ICT infrastructure level, the way of services provision, etc.

The first action was to start a procurement process to provision the first IaaS provider with the idea of infrastructure and services optimization in a new model of payment by use. In parallel as RREN, the adoption of a orchestrator role with its own cloud management platform (Opennebula based) to manage distributed resources in a real multicloud environment. The network design, the unified management and security conditioned the strategy.

Regarding the new external cloud provider and after an a intense procurement process, the company Nexica  resulted adjudicator for four years of the provision of IaaS services for Catalan Universities and CSUC.

Nowadays, the catalan institutions who are using this shared service are:

What work has already been done:

  • First IaaS provider procurement process.
  • Service catalog, service-level agreements and governance.
    Architecture redefinition.
  • RREN extended to the provider: Layers 2&3.
  • A new Opennebula cloud bursting driver was developed (VCLOUD compliance)
  • Integration of CSUC opencloud orchestrator.
  • Deployment of first production services.

TechDay Prague 2017 Wrap Up

This little post is here only to thank the people from CESNET for organizing the event. I also want to thank the attendees for sharing the day with me.

We’ve changed the format of the TechDay a bit and it turned out to be great:

  • The tutorial now is done in prepared laboratories in the cloud. This helped a lot for people with Windows or 32 bit laptops.
  • Instead of talks after the lunch there was a demonstration of OpenNebula and vCenter and a session of QA where the attendees could ask for specific features or how to accomplish some workflows.


Akamai and Harvard to Speak at OpenNebula Conf US 2017 in Boston


We are excited to announce that Jack Wadden of Akamai Technologies, and James Cuff and Justin Riley of FAS Research Computing at Harvard University will be keynote speakers at the Fifth OpenNebula Cloud Conference, the must-attend open cloud event, that will take place on June 19-20 in Cambridge, Massachusetts.
