OpenNebula 5.6 ‘Blue Flash’ is Out!

The OpenNebula team is proud to announce a new stable version of the leading open source Cloud Management Platform. OpenNebula 5.6 (Blue Flash) is the fourth major release of the OpenNebula 5 series. A significant effort has been applied in this release to enhance features introduced in 5.4 Medusa, while keeping an eye in implementing those features more demanded by the community. A massive set of improvements happened at the core level to increase robustness and scalability, and a major refactor happened in the vCenter integration, particularly in the import process, which has been streamlined. Virtually 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.

In this release several development efforts have been invested in making OpenNebula even better for large scale deployments. This improvements includes both, changes in OpenNebula core to better handle concurrency as well as refined interfaces. Sunstone dashboard has been redesigned to provided sensible information in a more responsive way. Sunstone also features some new styling touches here and there, and it has been updated to version 5 of Fontawesome.

Blue Flash also includes several quality of life improvements for end-users. In particular, it is now possible to schedule periodic actions on VMs. Want to shutdown your VM every Friday at 5p.m. and start it on Monday 7p.m. just before work… We got you covered. Also, don’t to want accidentally terminate that important VM or want to freeze a Network; now you can set locks on common resources to prevent actions to be performed on them.

5.6. ends the major redesign on the vCenter driver started in 5.4. The new integration with vCenter features stability and performance improvements, as well as important new features like a extended multicluster support or a redesigned importation workflow with new Sunstone tabs as well as a new CLI.

New integrations also bring Docker management. Any OpenNebula cloud can import from the marketplace a VM prepared to act as docker engine, allowing the deployment of Docker applications on top. Also, an integration with Docker Machine is available to seamlessly manage docker engines without having to interact with OpenNebula APIs or interfaces.

Following our tradition this OpenNebula release is named after NGC 6905, also known as the Blue Flash Nebula, a planetary nebula in the constellation Delphinus. It was discovered by William Herschel in 1784.

OpenNebula 5.6 Blue Flash is considered to be a stable release and as such, and update is available in production environments.

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 SetUID/SetGID functionality for VM Templates is funded by University of Louvain. The Ceph drivers enabling VM disks in the hypervisor local storage are funded by Flexyz B.V.

OpenNebula Newsletter – May 2018

Have a compact view of OpenNebula state by reading this monthly newsletter. Current development stages and overviews of following events are summarised in this document to keep our customers and community up to date.

This month OpenNebula travelled to Sofia and Barcelona for two splendid Technology Days. For this and more event related information go to the Outreach section of this newsletter.

For the OpenNebulaConf EU 2018, Amsterdam we are glad to announce some of the keynote speakers like Jonathan Grahl from King.com, German Gutiérrez from Booking.com, and Yordan Yordanov from Inoreader and we opened a Call for Presentations so that you can send us your suggestions for talks.

Technology

Facing the last weeks for the release of the new version of OpenNebula, the team is hardworking on bug fixing and fine tuning the software, so you can just sit and enjoy the experience of deploying and managing your own public, private or hybrid cloud.

For this reason we launched another hotfix release, OpenNebula 5.4.12 with minor bug fixes regarding importation of vCenter resources.

Now everything is ready for the release, we cannot wait much longer for you to try out all the new features coming with version 5.6 of OpenNebula. However we still need to do some testing in order to bring you a proven, trusty and stable software.

 

 

Community

We need you!!
Our software is widely used around the world, thus OpenNebula needs to speak all the languages possible for the good of the community. For this purpose we have launched a Call for Translations to which any of you can contribute in a really simple way. Read more about how to contribute in this short post with more details.

Now lets see some of the greatest contributions made by many of you. This month we have amazing news, keep reading!

What if we tell you that in next versions of Ansible you will have full integration for OpenNebula modules, with which to deploy VMs, create Hosts and Images? Well, this is not science fiction, it is a reality now!!!

Thanks to the work of the great Rafael del Valle and members of the Nordeus team, like Milan Ilic, we can say Ansible supports OpenNebula modules. This will make your infrastructure automation process a bed of roses. Ilic Milan has written this amusing article describing how to use Ansible to automate OpenNebula. Here you will find more detailed information of the functions you can use inside each module. It is indeed a good summary of the new OpenNebula modules inside Ansible.

One good example of this is shown by Digital Repositories on this tweet, where they tell how they use Ansible and OpenNebula for deploying VMs and automating processes on their own private cloud. You can see the work done and contribute to this modules in Ansible’s Github page.

We try to be updated with latest libraries and technologies to keep OpenNebula powerful and useful to our community. This is why we encourage you to demand new features through our forum or openning new issues in the Github repositories. For example @tobx and @jpfoures in our forum, demanded the integration of the new IOPS bursting option included in newer versions of QEMU libraries and we decided to include it for OpenNebula 5.6. You can find this love story in this forum thread ;)

Of course we have limited resources for developing all your demands, however as in this case, we are constantly listening to your demands and analyzing the viability for their development.
If you feel like you need some specific feature and you want it to be developed by our team you can follow this guide and contribute to the OpeNebula Project.
