OpenNebula 5.2 ‘Excession’ Beta is Out!

The OpenNebula project is proud to announce the availability of the first beta release of OpenNebula 5.2 ‘Excession’. OpenNebula 5.2 (Excession) is the second release of the OpenNebula 5 series. A significant effort has been applied in this release to stabilize features introduced in 5.0 Wizard, while keeping an eye in implementing those features more demanded by the community.

As usual almost every component of OpenNebula has been reviewed to target usability and functional improvements, trying to keep API changes to a minimum to avoid disrupting ecosystem components. Also, new components have been added to enhance the OpenNebula experience.


One important new module is the IPAM subsystem. In order to foster SDN integration, a important step is being able to integrate OpenNebula with existing IPAM modules, in those cases where outsourcing of IP management is required in the datacenter. Fitting in the OpenNebula architecture design principles, the IPAM subsystem interacts with IPAM servers using drives, and as such a IPAM driver lets you delegate IP lease management to an external component. This way you can coordinate IP use with other virtual or bare metal servers in your datacenter. No default integration is provided, but rather to effectively use an external IPAM you need to develop four action scripts that hooks on different points of the IP network/lease life-cycle.

Another great addition in Excession is the ability to use group bound tokens. The goal is to be able to use OpenNebula for different projects, which are identified with different groups. For instance, the same user can use OpenNebula for “WebDevelopment” project and a “BioResearch” one, for instance. This user can request a couple of tokens tied to each of these groups. Upon login with the “WebDevelopment” token, she will only be seeing resources from that particular project, and all new resources (VMs, images, networks) will be created within that group, isolating them from the “BioResearch” group. This feature is available both in the CLI and Sunstone, with helpers and dialogs to create, maintain and use the tokens.


All the OpenNebula drivers have been improved for robustness. For instance, a new default timeout (which is configurable) has been defined to identify hanging operations and kill crashed processes. In this regard, the EC2 drivers has also been thoroughly revisited, being updated to the v2 of the aws ruby gem, ensuring compatibility with all Amazon EC2 regions. Error handling has been improved as well in the EC2 driver, adding operation retries to circumvent those situations where the EC2 API is not consistent, and adding improved logging.

Sunstone is the face of OpenNebula for both administrators and users, and hence a constant target of enhancements to improve usability. Excession brings to the cloud table stabilized features that were introduced in the Wizard maintenance releases, like for instances advanced searches (that now are maintained regardless of tab switching), labels colors and ergonomics, improved vCenter dialogs and import tables (now with feature à la Gmail), hyperlinks to access resources displayed in the info tabs, and many other minor improvements.


There are many other improvements in 5.2 like revamped group mapping in LDAP authentication -now being dynamic mapping-, rollback mechanism in failed migrate operations, significantly improved fault tolerant hook -to provide high availability at the VM level-, improved driver timeout, vCenter storage functionality wrinkles ironed out, more robust Ceph drivers -for instance, in volatile disks-, improved SPICE support, improvements in ebtables and Open vSwitch drivers, multiple CLI improvements -imrpved onedb patch, password handling in onevcenter command, default columns reviewed in all commands- and much more. As with previous releases, it is paramount to the prject to help build and maintain robust private, hybrid and public clouds with OpenNebula, fixing reported bugs and improving general usability.

This OpenNebula release is named after the Ian M. Banks novel, a recommended read, as well as having a fitting slang meaning, “something so technologically superior that it appears as magic to the viewer.”. We are confident that OpenNebula, if not really appearing as magic, at least solves elegantly your IaaS needs.

The OpenNebula team is now set to bug-fixing mode. Note that this is a beta release aimed at testers and developers to try the new features, hence not suitable for production environments. Feedback is more than welcome for the final release.

The OpenNebula project would like to thank the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.

The group token functionality and dynamic LDAP group mapping into OpenNebula groups were funded by BlackBerry in the context of the Fund a Feature Program.

OpenNebula Newsletter – August 2016

Read this monthly newsletter to learn about the latest developments, events and future plans in all things OpenNebula and keep up to date with the state of your favorite virtualization manager. This newsletter suffered a minor delay due to the summer holiday break, we hope you understand!

The OpenNebulaConf 2016 is around the corner! Until the 15th of this month there is still a chance to register with the early bird price. The final agenda has already been published. You may also be interested in the sponsorship opportunities.


Summer vacations are over, and the team is focused on prepping the beta of the next major OpenNebula version, 5.2. The main goal of this release is to stabilize the wealth of features introduced in 5.0, but several outstanding functionality has been introduced as well:

  • New IPAM module, a general mechanism to integrate with different IPAM servers
  • Enhanced user authentication tokens, which binds to specific groups and allows to maintain different sessions with the same user account working in different projects
  • Usability improvements in Sunstone and CLI
  • VM migration between clusters
  • Better VM fault tolerance hook
  • Improvements in ec2 hybrid drivers and vCenter drivers

Also vOneCloud, the appliance encapsulating an OpenNebula tailored for vCenter infrastructures, has a new version as of this past month, namely version 2.0.1. vOneCloud 2.0.1 is based in OpenNebula 5.0.2 and as such it includes all the bug fixes and functionalities introduced in 5.0.2. New functionality includes resize capabilities for the Virtual Router (VR), as well as a new VR Template instantiate action and the possibility to modify cardinality of the Virtual Router HA, Sunstone labels now have colors, search users by password field, implement oneuser login in Sunstone and a service create dialog in the admin view. You are welcome to try vOneCloud out, it is fully open source and zero intrusive!


We are proud to count as members of the OpenNebula community members of useful software that uses the advanced features of OpenNebula to offer top notch products, like the one developed by folks at UDS to manage VDIs.

Also proud to learn that new software being released to resource centers management support OpenNebula as part of their default distribution, like the INDIGO project does.

It is also nice to learn how OpenNebula can be integrated with other technologies to create better solutions, like with Vagrant as known by Florian.

Having people that knows the project inside out and are willing to defend it is a good motivation to keep up with the excellence of the project. Thanks Nodeweavers!

Outstanding to have people also willing to create material around OpenNebula knowledge, check this out. And being included in articles named Five open source cloud tools admins need to know makes our faces red with blush (the good kind!).

Big thumbs up to all the maintainers of the OpenNebula ecosystem for their new releases (during August, no less!). New versions of Net::OpenNebula Perl module, Test Kitchen Driver for Opennebula, the ruby gem to clean forgotten iptables rules, driver for creating OpenNebula instances in Chef Provisioning and the OpenNebula provider for Vagrant where releases this last month.

This last month member of the team travelled to fabulous Las Vegas to attend the VMworld 2016 US where vOneCloud had its own booth in the Mandalay Bay Convention Center. A very positive experience with lots of interest on behalf of the attendees that saw first hand how vOneCloud can be used to easily provision vCenter resources to end users through a slick self-service portal.

The OpenNebula team will be present in the VMworld 2016 Europe, October 17 – 20, Barcelona (Fira Barcelona Gran Via). We will be featuring also a vOneCloud booth, so come round to see a live demo if you are in town, or to ask anything about all things OpenNebula.

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.
