The OpenNebulaConf 2016 will be held in Barcelona on the 24-26 of October. The preliminary agenda has already been published, the final version will soon be available. You might be interested in taking a look at the sponsorship opportunities. Check out the list of upcoming OpenNebula TechDays to see if there is one on your doorstep that you cannot miss.


The first stable release of OpenNebula 5.0 Wizard has been published. The OpenNebula project is proud to announce the availability of the first stable release of OpenNebula 5.0 ‘Wizard’. This major update comes with several improvements in different subsystems and components, with minimal changes in the API and the VM life-cycle states, which embodies long overdue changes but implemented to minimize the impact and ensure backwards compatibility as far as possible.

Also, a new maintenance release 5.0.1 fixing bugs reported by the community has also been published this month, fixing fix Ceph pool names, VM Template update wizard, oned crashes when a context variable contains a filter, PCI element in KVM deployment file, better checks for IPv4 strings, wrong attach disk in vCenter, VM instantiate when NIC contains a fixed IP, migration for STOPPED and UNDEPLOYED states and the apptemplate generation. We would like to thanks all members of the community that contributed hugely with their evaluation of the beta, RC and final stable version and provided feedback on it.
Based on 5.0 Wizard, also a new release of vOneCloud, 2.0, is available for download. vOneCloud is an OpenNebula distribution optimized to work on small VMware vCenter deployments. This new release of the appliance, based on a tailored version of OpenNebula 5.0 Wizard to ease the provisioning of resources from vSphere based infrastructures, comes packed with exciting new features:

  • Datastore and VMDK image management, as well as import.
  • New Virtual Router Resource, to allow routing between isolated virtual networks.
  • More flexible vCenter VM naming, with a configurable prefix.
  • New resource pool mode, with the ability to select in which resource pool a particular VM is confined.
  • New OneFlow templates operations, like the ability to clone existing service templates.
  • Keep disks on done, to avoid deleting disks when the VM is terminated.
  • Instantiate to persistent, to easily create a rich VM Template catalog.
  • Dynamic VM reconfiguration, that can be performed while the VM is running or powered off.


We cannot emphasise this enough. The OpenNebula community is continuously contributing to the OpenNebula maturity and success, and we would like to thank you all for your excellent feedback on the several betas and RC of 5.0 Wizard.
Also, the amazing job of the different translators has enabled the availability of the Sunstone web interface to 20 different languages. Kudos to you!
The community shows its engagement in integrations like this one between OpenNebula and the Happy module by EOLE team, GO bindings for the OpenNebula Cloud API (OCA) by Megam and OpenNebula and Foreman by Netways. This enriches the OpenNebula ecosystem and shows its health, thanks!
Also important is to spread the word, with initiatives like users groups and local meetups and workshops. Also welcome are reviews in blogs, like this one about vOneCloud 2.0 (In French), or this excellently crafted post on OpenNebula and Docker Swarm with consul.
And, as usual, is very good to be reminded about nice things, like for instance the amount of years we’ve been working to make OpenNebula a mature product that you can find today.
