Technology

As mentioned last month, we are immersed in a furbishing process for our next big release OpenNebula 5.6, which is around the corner. For this purpose we have published a new hotfix release, OpenNebula 5.4.9, resolving many of the issues reported by our community members. Within these fixes you can find:

  • vCenter issues related to disk and network monitoring have been solved.
  • vCenter driver allows template instantiation without duplicating the MAC address
  • qcow2 driver is automatically selected when a volatile qcow2 disk is added
  • VNet datatable now shows correctly in groupadmin views

The full list of improvements can be found, as always, in our documentation. If you are curious and want to see the technical details, feel free to glance at the official Github repository.

vOneCloud 3.0.5 release!

Alongside with OpenNebula 5.4.9 we have made a new release for users using vCenter. All the fixes and improvements on 5.4.9 and more are available in vOneCloud 3.0.5. Download the package at vonecloud.today.

Have a look at this blog post for further information.

Moreover we have been working in some of the new features for OpenNebula 5.6. The one we are more excited about is the new Lock functionality. With this new tool, cloud administrators using OpenNebula, will be able to lock any resource within the cloud infrastructure (VMs, users, networks, datastores, disks…) We aim to give more control to the users over the their cloud elements.

Looks good right? Stay tuned to get the latest news!

Community

Let’s see what has been going on around our community.

Having a quick look at our forum we noticed the increasing number of contributions, answers and questions of all kind. We want to congratulate all the active members that are sharing their knowledge with the rest of the community. Also we would like to propose a big toast for our Champions and all the users that are acting as ambassadors of OpenNebula on the wild wild internet.

If you want to become an OpenNebula Champion, read our introductory page and see all the benefits of becoming a champ!

OpenNebula’s community is very happy to welcome Inoreader. They have successfully migrated from Bare-metal servers to OpenNebula + StorPool, which means they now operate on a cloud environment with full control over their resources. Cheers for that!

This was an amazing achievement, therefore, Inoreader team has written a very detailed article, describing all the processes, architectures, implementations, installations, integrations and many other experiences happening during the migration. We encourage all of you to have a look at this extensive whitepaper, It is very interesting, simple to read and shows how this migration is possible with OpenNebula. However, if you are a not so experienced user, but still, want to know about this process, do not worry, Inoreader colleagues are preparing a shorter article which we will publish in our blog shortly.

Find Inoreader’s article here and enjoy the reading.

Moving on, we have a great proposal for Ansible’s github project: add one_vm, one_image and one_service modules to manage VM instances, images and services on OpenNebula cloud platform. As the creator says, they have been using these modules in a production environment for the last 3 months and also the integration tests are working. You can see some code on their github repository.

Great news also coming from Telefonica and Amazon. We found out that Amazon is in talks with Telefonica to support its Greengrass edge-computing service, which will allow customers to run cloud computing from end-user devices instead of in large data facilities. This is going to be possible thanks to Telefonica’s facilities which are using OpenNebula in their edge cloud computing deployment. Find more about this move on this article written by Ian Morris for Light Reading

Another successful case study!

This time Université Catholique de Louvain in collaboration with UDS Enterprise, bring us this VDI platform that makes possible for their students to access virtual classrooms as if they were in the standard computer classroom, being able to use the same software as in their labs, anywhere, anytime and using any device.

“the IT staff is really satisfied because they can work with the Open Source KVM-based cloud orchestrator OpenNebula, which is really useful for them.”

Follow this link to discover more details on how this was achieved.

OpenNebula team wants to thanks Computing For Geeks for making a great tutorial about Installing OpenNebula Front-end on CentOS 7. If you are planning to start learning about OpenNebula this tutorial is a great starting point, anyhow if you find any difficulty or need further explanations, check our documentation and ask for help in our forum.

OpenNebula Newsletter – February 2018

One more month this newsletter acts as a brief summary of OpenNebula’s progress. In this newsletter, you will read about new release features, event details, calendar updates and important community contributions during the last month.

Remember, the big event of the year will be the OpenNebulaConf 2018 which will be held in Amsterdam at the end of the year. Passes are being sold right now, do not miss the chance to come!.

Technology

As we prepare our next big jump to OpenNebula 5.6, the team wants to make sure that everything is up to date on 5.4. This is why this month OpenNebula developers have put all the effort on streamlining the current version with the 5.4.7 and 5.4.8 hotfix releases.
Most of this changes were demanded by community members, thanks to the feedback we were able to fix the following:

  • Make vip sh less error prone
  • Instantiate VM with volatile image
  • Resize VM disk
  • Moref sharing, now works on multiple instances of vCenter

Of course this is just a summary, you can check the full list of changes in our documentation or in our github.

Attention spoiler alert!
We have been working on Hybrid Clouds, improving Amazon EC2 and One-to-One drivers. With this new One-to-One driver we aim to ease the communication between OpenNebula instances.
However, this is just a little leak on what will be available on OpenNebula 5.6.

Community

As an open source project an important part of our labor is to maintain and give support to our community. But as the saying goes “He who gives, receives much more in return” and we receive tons of great contributions, initiatives, answers and many other feedback from our community, and this is for us a source of pride!

Several companies like StorPool, Linbit, Nodeweaver, Virtual Cable, Virtuozzo and DET-IO have signed in the new OpenNebula Ecosystem. Joining our Partner Ecosystem is a really simple process that you can complete following this guide.

It was great to discover, while creating our new Ecosystem how OpenNebula can be integrated with other technologies to provide great solutions. One example is Virtuozzo 7 which will be integrating OpenNebula as an advanced but simple control panel for their infrastructure components. Virtuozzo’s team has made a pretty clear and simple tutorial for installing OpenNebula on top of Virtuozzo 7 which is worth having a look at.

A pleasing discovery was the support for OpenNebula 5.x included by UDS Enterprise. They have written an enlightening post explaining the great advantages of publishing virtual desktops on OpenNebula.
Also you will find an amazing video showing the integration in action, in this video you will see how UDS Enterprise is able to create 1 virtual desktop on OpenNebula every 3 seconds!

StorPool team has made a Reference Architecture document describing the architecture of a complete IT infrastructure including storage, computing, networking and cloud orchestration. This document is very complete and didactic.This is why we recommend reading this paper to learn more about different architectures integrating OpenNebula.

Another great initiative came to us via twitter, where we saw that the team of runtastic has developed an OpenNebula provider for Terraform. You will find a use example and how to contribute notes on the github repository.

Seeing that people are organising some technical meetups regarding OpenNebula, such as the one organised by Computer Port are always great news, this is a good way to teach OpenNebula all around the world and we truly appreciate it.

To finish this community section we would like to congrat all of you that have started new personal or professional projects using OpenNebula, some times it is hard when you start with a new technology, but at the end you will find all the benefits OpenNebula brings to your work. This happened to @kore_less that tells on this tweet:

It took its time, and mistakes and more mistakes, and configs and more configs… But finally I have the base for my project up and running. OpenNebula running on the first node!

We would like to encourage him and all the users like him to continue with this great job and contribute to our project with their feedback, asking and answering using our forum.

Outreach

To start, just a quick reminder that OpenNebulaConf 2018 will be taking place on the 12-13 of November in Amsterdam. Just a few days ago, we announced the very early bird registration and the Call for Sponsors. Gerhard Sternath, CFO at Linbit, already confirmed their attendance via twitter and in a few days we will welcome LINBIT as our first Platinum sponsor. We are hoping to see you all there, to exchange knowledge and most important, to live this amazing experience and enjoy it.

We are excited to present the OpenNebula’s Techday calendar for 2018. Our Call for Hosts was welcomed by many partners and thanks to them members of the OpenNebula team will be visiting Bulgaria, Barcelona, Cambridge, Santa Clara and La Habana. The Call for Hosts is still in progress so if you want to be hosting one of our TechDays you are still on time. Read carefully our information page listing the needed steps.

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.

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

OpenNebula Newsletter – October 2017

A summary of the activity of the OpenNebula project this last month.

The OpenNebulaConf EU 2017 happened this month in Madrid, with keynote speakers including BlackBerry, Trivago, Runtastic and the Ministry of the Flemish community. More information in the wrap-up post, where all the videos, pictures and slides for the conference has been made available.

Technology

OpenNebula Systems added as a benefit for support subscriptions hotfix incremental releases. While OpenNebula is fully open source, packages from hotfix incremental versions are not publicly released, and are only available for users with an active commercial subscription. However, rest assured that the code is publicly available in the GitHub repository, as is the templates to create packages for the different supported platforms.
A new hotfix release for Medusa, 5.4.2, (you can learn more about hotfix releases in this link), has been released. Some new functionality is available in 5.4.2:

  • Show key instead of value for restricted attribute
  • Enable template save as for vCenter
  • Better error messages in get_dc function

Also, a numerous set of bugfixes were included in 5.4.2.

The team is finishing the roadmap for the next OpenNebula version, 5.6. Not a lot of time or space to fit more functionality, but it is still worthy to let us know about the features you’d like to see in OpenNebula!

Community

A beautiful post about CloX, a solution based on OpenNebula and LXD, features in the OpenNebula blog this month. We think CloX shows one of the many strengths of OpenNebula, it’s small footprint, which enables several interesting use cases.

you can expect an easy of use, fully featured cloud orchestrator with minimum overhead, great performance and reduced deployment times. CloX is meant to be deployed over Single Board Computers (SBCs) based on ARM processors providing low capital expenses and power consumption.

Newcomers might find it hard at the beginning to understand all the concepts behind the OpenNebula platform. This is why having the community produce detailed tutorials on how to install OpenNebula in specific platforms, such as this example, are great contributions to the project since they go at great lengths to foster OpenNebula adoption.
It is always a pleasure, and a great honor, to discover new services and business that base their IaaS management needs on OpenNebula, like Wedos VPS does, as well as several other hosting companies.

As usual, we want to give two thumbs up to the brave people that helps other OpenNebula users in the community forum. Kudos to you!

This month of August was also good news for vOneCloud users, with the release of vOneCloud 3.0.0 (and subsequent 3.0.1), which brings all the innovation introduced in OpenNebula 5.4. You can check the details in the release notes, the following are highlights of the new functionality in vOneCloud 3.0.0:

  • Enhanced storage management, vOneCloud is fully aware of all VMs disks. Non-persistent images and volatiles disks are now supported.
  • Storage quotas and datastore capacity check, never run out of capacity correctly dimensioning the available datastores and the storage quotas given to end users
  • Linked clone support, add support for linked clones for VMs at the time of importing a VM Template
  • Disk resize capabilities, resize the capacity of a VM disk at boot time or when the VM is in poweroff
  • Network creation support, a new vCenter network model is available in virtual network definition, standard and different port groups and vSwitches can be created from within OpenNebula. VLAN IDs, MTUs and number of ports can be specified when a port group is created.
  • Full storage and networking support in imported VM Templates, images and networks representing disks and network interfaces are created for VM templates and folder placement features.

Community

The team put a lot of effort in Medusa, and we want to thank you for the marvellous feedback received in the community forum, as well as the support given by the community to newcomers and people willing to upgrade their OpenNebula infrastructures.

It is also very welcome how people are keeping up to date with the latest releases. We hope you enjoying using OpenNebula as much as we enjoy developing it!

Integrations such as this one from UDS Enterprise gives indeed more flexibility to OpenNebula, with the ability to manage a VDI environment in an OpenNebula based infrastructure.

Release 5.2-4.1 of the LXDoNe OpenNebula addon has been released. LXDoNe add LXD management capabilities to OpenNebula, bringing container management to the cloud!

Outreach

The OpenNebulaConf EU will take place in Madrid, Spain, this October. The conference will be packed with very interesting talks about the real world uses of OpenNebula, check the agenda for more details, keynotes feature BlackBerry, Trivago, Runtastic and the Ministry of the Flemish community. Also, make sure you register if you’ll be on the area! The conference is a great place to learn about OpenNebula and cloud computing in general, don’t take our word for granted and watch the talks in the YouTube playlist, download the slides or take a look to the pictures of the first US edition of the OpenNebulaConf that happened in Boston this past June.

The next OpenNebula TechDay will happen in Vancouver after the summer break, the 1st of September, hosted by Best Buy Canada. The event is almost full, so if you are in the area make sure you register a soon as possible, or risk missing the opportunity!

OpenNebula Newsletter – July 2017

Check out the highlights of the OpenNebula project this last month regarding technology, community and outreach in this monthly newsletter of your favourite cloud management platform.

The agenda for the OpenNebulaConf EU 2017, in Madrid this October have been announced, including BlackBerry, Trivago, Runtastic and the Ministry of the Flemish community. Also, you can check the videos, pictures and slides of the OpenNebulaConf US 2017 in this post.

Technology

OpenNebula Medusa 5.4 is out in the wild, and the team is now analyzing carefully the feedback given by users to identify any issue with the release. So far things are looking good, the team will probably be releasing a 5.4.1 maintenance release in September to address the minor issues seen in the forum.

In Medusa, 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. Three major features that are important to highlight follow.

An important focus has been on the vCenter integration, with an enhanced network and storage management. Also, new components have been added to improve the OpenNebula experience.

  • Full storage management. Non-Persistent images are now supported as well as volatile disks. OpenNebula is now aware of all VM disks and storage quotas can be enforced. Support for linked clones and Marketplace.
  • Full network management. It is now possible to create vCenter standard and distributed port groups and even vSwitches directly from within OpenNebula. You can assign a VLAN ID to a port group created by OpenNebula.
  • Improved monitoring. Up to two orders of magnitude of speedup.
  • An enhanced import process where naming limitations in imported resources has been removed and the ability to enable VNC automatically for Wild VMs.
  • Disk resizing, VM and Templates folder selection when a VM is deployed… and many more changes!

A new resource, the VM Groups, has been added to implement VM-VM and VM-Host affinity/anti-affinity rules. A VM group is a set of related virtual machines that may impose placement constraints based on affinity and anti-affinity rules. A VM group is defined as a set of Roles. A Role defines a VM type or class, and expressions to the VM Group can be added to define affinity between VM roles, or between VM and hosts. This ensures a dynamic approach to affinity/anti-affinity since new VMs can be enrolled to a particular Role at boot time, after the VM Group has been defined and other VMs added to it.

OpenNebula 5.4 brings to the table a native implementation of a consensus algorithm, which enables the High Availability deployment of the OpenNebula front-end without relying to third party components. This distributed consensus protocol provides fault-tolerance and state consistency across OpenNebula services.

And many other new features that can be checked out in the Medusa release notes.

The team is working now on a new release of vOneCloud, 3.0, which is going to bring all the excellence in vCenter management exposed by OpenNebula 5.4.

Community

Even in summer, the OpenNebula community does not go into vacation mode. It seems that it never sleeps

Spreading the word is a great support for the project, and it is very good news to learn how OpenNebula enables learning computer science and makes teachers jobs easier.

Software integrations with third party applications, like for instance this VDI (Disclaimer, tweet in spanish) really enriches the OpenNebula ecosystem.

Equally important are the maintenance of OpenNebula addons. Contributing an addon is great by all means, but maintaining it and extending the documentation, ie, keeping it alive, is what really makes it useful for future OpenNebula releases. This is why notices such as this new version of the LXDoNe or new documentation for the vCloud driver are very good news!

Outreach

The first ever OpenNebulaConf in the US was held this past June, in Boston to be precise. We had a lot of wonderful attendees and some really great speakers delivering really interesting talks and sharing their experiences. We would like to thank all attendees and speakers for their support. If you missed the conference, now you have a chance to watch the talks in the YouTube playlist, download the slides or take a look to the pictures of the conference.

The agenda for the next edition of the OpenNebulaConf EU that will take place in Madrid, Spain, this October. The conference will be packed with very interesting talks about the production use of OpenNebula, so make sure you register if you’ll be on the area!
