The team has rev the engines for the next major release, OpenNebula 5.6. Stay tuned for exciting new features!

Community

We are having a very intense year kickoff, this means, great news for and from our community!

OpenNebula team wants to welcome OneHost Cloud. They announced recently via Twitter, OneHost is migrating from OpenStack to OpenNebula.

We have chosen Opennebula to build our new cloud platform which will provide increased performance and simplicity for our current and future customers.

We recommend reading this article where the reasons for this change are listed and explained. It was amazing to find out that before making this turn, OneHost Cloud consulted experts on cloud:

after consulting many experts in the cloud arena we have felt comfortable implementing such platform to replace our current VMware and Openstack cloud

An enlightening tutorial was made by our colleagues from Pandora FMS. In this tutorial you will learn how to do the monitoring of your cloud using OpenNebula, along with other useful tips.

NodeWeaver team has released, for all of you, their LizardFS drivers for OpenNebula. This is a great chance to try out this amazing storage technology. To install this new drivers you can follow the guide on the github repository.

Another amazing addon was developed by a member of our community, Kristián Feldsam. With this addon you will be able to make backups of your qcow2 images inside OpenNebula. Read the post for more information

Cheering news coming from Virtuozzo. They have added support for OpenNebula. Now users will be able to manage their Virtuozzo Hyperconverged Infrastructure through OpenNebula. All the benefits of this synergy are described in this excellent post, written by, Stanislav Khalup, program manager at Virtuozzo.

As announced in our forum, one of our most experienced users, Rafael del Valle, has created PyOne, which is a fantastic implementation of OpenNebula’s XLM-RPC bindings in Python. If you are interested in seeing how this works check this link.

Also this month, Valentina Zaccolo from the National Institute of Nuclear Physics in collaboration with INDIGO DataCloud, has published a very interesting post related to the implementation of a Fair Share Scheduler for OpenNebula. We already heard about it in our last OpenNebulaConf, but do not worry if you couldn’t assist, this article is very explanatory and easygoing.

Our team is very excited to see these type of contributions which not only help OpenNebula, but all the users of the community. If you feel like you can help our community anyhow, do not hesitate to contact team or post directly in our forum.

Outreach

OpenNebula goes to the Netherlands! One more year we are doing the OpenNebulaConf2018 and this year it will take place in Amsterdam, one of the most modern cities in Europe. We are very excited about it because we will be presenting OpenNebula 5.6 with all its new amazing features and probably we’ll be scooping some characteristics of OpenNebula 5.8.

Countdown is on, the date chosen for this OpenNebulaConf2018 is November the 12-13, you can’t miss the chance to come and enjoy our hands-on tutorials and listen to our community speakers which will talk about why they are in love with OpenNebula.

A quick reminder for all of you that have not attend past OpenNebulaConfs. If you are interested in coming to OpenNebulaConf2018 and want to see previous events, check this link and have a look at the videos, pictures, talks, tutorials, etc.

We will be updating this information in our OpenNebulaConf official website. In a few days we will also publish the TechDay and training schedule for 2018, stay tuned!

New Maintenance Release: OpenNebula 5.4.6

The OpenNebula team is pleased to announce the availability of OpenNebula 5.4.6, a new maintenance release of the 5.4.x series.This version fixes multiple bugs and add some minor features, specially relevant the possibility to setting the CPU model to alleviate the performance penalties of Meltdown OS fixes.

Check the release notes for the complete set of changes.

Relevant Links

Mitigating Meltdown Performance Penalty

We are sure you are aware of the various OS patching going on to mitigate the Meltdown and Spectre security flaws.

If all your hypervisors support PCID, you can activate this for all your new VMs setting the following in your `/etc/one/vmm_exec/vmm_exec_kvm.conf` file (and restarting OpenNebula afterwards):

RAW = “<cpu mode=’host-passthrough’></cpu>”

Note that this may impair live migrations of VMs between hypervisors with heterogeneous CPUs.

The OpenNebula team is working towards an easier way to define this option on a per-VM basis, as well as support from the scheduler to pick compatible hypervisors. This will be available to the community shortly through a public maintenance release (5.4.6).

OpenNebulaConf Coming to Amsterdam in November 2018

We are happy to announce that the seventh edition of our community conference will be held in Amsterdam on November 12-13 2018.

OpenNebula Conferences are education events that serve as a meeting point of cloud users, developers, administrators, integrators and researchers, featuring talks with experiences and use cases. They also include tutorials, lightning talks, and hacking sessions that provide an opportunity to discuss burning ideas, and meet face to face to discuss development. Previous speakers include Santander Bank, CentOS, European Space Agency, Akamai, FermiLab, Puppet, Red Hat, BlackBerry, Harvard University, Telefonica, Akamai, Runtastic, Unity, Citrix, Trivago …

And remember… OpenNebulaConfs are vendor-neutral events focused on real-world practices and how to successfully implement open source in your cloud.

We look forward to seeing you in Amsterdam!

New Linux Contextualization Packages

We have released new Linux contextualization packages (ver. 5.4.2) with wider platform support, a few improvements and bugfixes. This release is a major update. New packages are available for download on the GitHub with updated documentation for KVM/vCenter environments. Packages are compatible with the OpenNebula versions from 4.6 to 5.4.

The main focus of this release was to come again with updated packages for the Amazon EC2 environments used via OpenNebula Cloud Bursting; these packages weren’t updated for some time. Currently, only main systemd platforms CentOS 7, Ubuntu 16.04 and Debian 9 are supported via the dedicated one-context-ec2 packages, but other similar systems should work as well. Also, we have aligned the support for Alpine Linux contextualization (formerly maintained in the separate repository) and merged the required changes into the general Linux contextualization repository. From this release on, we provide the Alpine Linux package for easy setup. A fix contributed by Dmitry Tyzhnenko ensures the sudo configuration is created, if the contextualized user (specified via context parameter USERNAME) is different to root. There are also several bugfixes in the scripts, dependencies, and package creation. Please see the complete release notes on the download page.

On top of that, new KVM appliances with Alpine Linux 3.6 and Fedora 27 were added, and most of our existing generic Linux KVM appliances were updated on the OpenNebula Marketplace.

We have added the very new EC2 contextualized appliances on the OpenNebula Marketplace for a quick start with the OpenNebula Cloud Bursting on the Amazon EC2! These are available for the current generation of the EBS based HVM instances in the EC2 region us-east-1.

In case of any questions, you can use our public forum or submit an issue on the GitHub.

 

 

 

 

OpenNebula 2017: Year in Review

As we quickly finish the last hours of 2017, we want to recap on what it meant for OpenNebula and summarize the huge achievements and milestones that the project had throughout the year.

OpenNebula turned 10 years old in 2017. We believe this is an astounding accomplishment by an infrastructure open source project that has achieved a high degree of matureness, and we would like to thank the OpenNebula community for their support. It wouldn’t be possible to achieve the adoption that OpenNebula has without your interest and engagement. We’d like to thank specially the project contributors for the efforts in bringing excellence to the cloud management platform field.

Some great improvements have been introduced this year in OpenNebula. Blackberry’s request for VM Groups was a great challenge but finally we could add this new feature in OpenNebula 5.4. Also the University of Louvain has funded new enhancements such as the Non-SLAAC IPv6 Address Range and the configurable image persistence setting. We would like to thank these sponsors, as we understand it they are helping not only the OpenNebula project but also the open source community.

OpenNebula adoption keeps striving at a healthy pace. We are proud to count very large scale infrastructures spanning across datacenters and based on heterogeneous virtualization, storage and networking platforms. We are happy to continue the same download rate as last year of OpenNebula packages served by our repositories, not counting the OpenNebula packages included in the most popular Linux distros.

Two important releases were deployed this year, OpenNebula 5.4 and vOneCloud 3.0, introducing significant features.

OpenNebula 5.4 (Medusa) arrived in June with a great acceptance among our users. Since then, 5 incremental releases were deployed to fix and improve this new software version. One of the major improvements is the native implementation of RAFT consensus algorithm which enables the High Availability deployment of the OpenNebula front-end without relying on third party components. VM groups were born this year, now any user will be able to group virtual machines depending on their role, activity, resources… Thanks to the feedback from our community, we know that this new feature is being really helpful for many of you. Cheers for that! You can follow the changelog on our documentation page to check this release or any previous one.

The OpenNebula team managed to implement full storage and network management capabilities on vOneCloud 3.0. Of course we did many more things that you can check on the release notes. Meanwhile, documentation has been updated to match this last vOneCloud release.

The OpenNebula community are most active than ever. 2017 was the year of amazing contributions to the OpenNebula ecosystem, ranging from support to LXD containers to many other contributions like addons, functionality patches, feedback for future releases, messages in the forum, twitter and so on. If interested in learning more about these contributions, along with other details about the great progress that we have seen for the OpenNebula project, check our monthly newsletters.

This year the first OpenNebulaConf in the US was held in Boston where important institutions such as Harvard, Akamai and Telefonica showed the multiple advantages of using OpenNebula. If you missed it or just wish to review the talks and courses given, check the web page of the conference. One more year the OpenNebulaConf in Europe was a success with people attending from everywhere around the world. This meeting was held in Madrid and was a two day long event where the people from Runtastic, Blackberry, Trivago and many other companies spoke about how they use OpenNebula and why. If you are interested on what they said you can find slides, pictures, videos and many other content in the conference’s website

In addition OpenNebula experts were present at the TechDays organised all around the globe. These events aim to teach and show the advantages of using OpenNebula. Of course this would not have been possible without our beloved hosts that prepared a warm and nice environment for our TechDays talks: Bit in Netherlands, Best Buy in CanadaFlyTech and CSUC in SpainStorPool in BulgariaTelefonica in SpainCESNET in Czech Republic….

Finally, same as in 2016, we want to highlight the participation in both VMworld editions, Europe and US, where the team were showcasing vOneCloud functionality over vCenter, with massive improvements like full networking and storage support. We are planning to come back in 2018 with even more advanced functionality, so stay tuned!

OpenNebula Newsletter – December 2017

As expected, we have been working hard to finish 2017 stronger than ever. Below you will find a brief recap on the work done this month to keep OpenNebula ready.

The amazing response from our community to the call for TechDay hosts published last month is just another sign that things are going great around OpenNebula and we appreciate the effort. The schedule of events for 2018 will be published within the first weeks of January. Now we are focussing on keeping everything prepared for the upcoming year, which seems to be full of new and amazing challenges.

Technology

Improvements on Sunstone and the EC2 drivers were introduced this month. These came along with our two latests hotfix releases: OpenNebula 5.4.4 and 5.4.5.

An even faster Sunstone? Yes!

Our team managed to improve Sunstone’s load times so you can focus on your cloud administration. Some other suggestions have been implemented such us the request to make changes on the settings page and increase the disk size with the beautiful Sunstone slider. For the EC2 drivers some issues related with custom userdata have been solved successfully, also we made it possible to add EC2 target hosts through Sunstone.

But this is just a little summary, you can check other changes and enhancements on the following links:

We never give up! Even though migrating from Redmine to Github was a very tedious job, we managed to label all the issues correctly and in a cleaner way.

Community

As an open source project, OpenNebula needs the support of a proactive community of users, which we are glad to have!

It is a pleasure for us to see how you interact with each other solving doubts and asking questions. However, to enhance the activity of our Forum we have an active support team trying to solve your questions at any time. Feel free to ask and answer any question and if you are not yet part of our amazing community you can register with a few clicks at the forum’s main page.

Great news coming from Germany. Adacor Hosting now manages it’s virtualization system using OpenNebula. They published an interesting article where you can find the reasons for their change from OpenStack to OpenNebula.

OpenNebula is an open source cloud solution that provides a highly available, scalable and highly efficient virtualization platform

Another inspiring article, this time about vOneCloud, can be found here . In this article you will find an overall explanation of what vOneCloud can do for you, along with some useful links for downloading the latest vOneCloud release.

vOneCloud is for companies that want to create a self-service cloud environment on top of their VMware infrastructure without having to abandon their investment in VMware and retool the entire stack.

It is also worth noting that Virtuozzo now seamlessly integrates with OpenNebula. Therefore OpenNebula can be used as the orchestrator of this fine hyperconvergence platform. This is very good news for the OpenNebula ecosystem!

We are pleased to announce support of OpenNebula as a management panel for Virtuozzo’s Hyperconverged Platform. By combining the vast capabilities of OpenNebula with Virtuozzo-specific features of hypervisor and software defined storage, users are able to take advantages of the combined synergies
