OpenNebula Newsletter – January 2016

Check this Newsletter to find out the what kept us busy this month: latest developments, events and future plans for the upcoming months.

We are starting this 2016 willing to share with the OpenNebula community another chapter of excellent cloud management. If you, as we do, like planning ahead check the sponsorship opportunities for the next OpenNebula Conf 2016, due in October in Barcelona. Take a look also to the projected OpenNebula TechDays for this year.


The OpenNebula team, after the release of a new maintenance release for Great A’Tuin, the 4.14.2, is working around the clock on the next upgrade of OpenNebula, v5.0.
This new version will come packed with features and interface changes to iron out the wrinkles in the user experience, to make the experience managing and using an OpenNebula cloud even smoother. vCenter storage management (you are right, including datastore selection and disk hotplug), fully integrated virtual router management (including default and transparent HA for routers), marketplace datastore to easily import/export images to other OpenNebula clouds (we think this is a badass feature), Cloud View improvements, and a long list of other features. As a teaser see this blog entry about resource tagging in Sunstone to keep VMs, networks, images and templates perfectly organized.

Results from the last survey, aimed to understand the use of OpenNebula by the community, has been analyzed and published in the blog. After a careful filter, 190 organizations were chosen as a representative sample of the community. The main changes with respect to the last, 2014 survey are (read a more extensive report here):

  • OpenNebula shows its increasing maturity, with 73% of deployments in production compared to 62% reported in our previous survey.
  • Growth in North America has accelerated, now representing 30% of responses, up from 20%.
  • KVM provides the majority of OpenNebula support, growing from 48% to 79%.
  • There is a high rate of adoption in VMware environments from 28% to 37%.
  • Ubuntu grows from 36% to 40% and Debian falls from 33% to 22% as OS to build the cloud.
  • The use of the EC2 cloud API decreases from 25% to 10%.
  • The use of Ceph has grown considerably from 17% to 40%


The OpenNebula community never sleeps! Well, that may be an overstatement, but certainly when they don’t they contribute to the common knowledge as well as come up with cool integrations to enhance the already mighty power of OpenNebula clouds. Floating IPs for OpenNebula can be easily achieved now thanks to this nifty tool developed OpenNebula clouds, developed by the same authors as CloudVAMP and Docker drivers.

Billing is crucial for VPS providers, which will greatly benefit from this provisioning module for Blesta which can be plugged into OpenNebula infrastructures.
It is crucial for an open source project such as your favourite cloud management platform to receive its users feedback. As you may heard from us before (once or twice), our roadmap is defined using our knowledge of our user and community developer needs. This is why it is so important messages like this one, with very useful feedback to be taken into account in future OpenNebula releases. Thanks, keep up the good work!


Recently after our last OpenNebula Conference (talks, slides,pictures), the next, 2016 edition have been announced!. We know it is hard to plan that much in advance, but if you are willing to attend and can save now the date you can take advantage of a huge 40% discount in your Conf tickets.

Remember our December newsletter? We said you should stay tuned for the OpenNebula TechDay schedule in 2016. If you did then you already know about the quite a few already scheduled TechDays around the world for this year, to which we promptly added others in US. The OpenNebula Cloud TechDays are full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop, and presentations from community members and users. TechDays hosts have an important role, and that is the local promotion of the event to gather OpenNebula enthusiasts in this technical event. If you are interested in participating in (or hosting) any of these TechDays agenda let us know.


OpenNebula was spoken of in the Journée interministérielle du libre 2016 in France, country which recommends OpenNebula in their open source software reference list. Rubén S. Montero, our chief architect, gave an interesting interview to DatacenterDynamics magazine, check it out.
