OpenNebula Newsletter – July 2018

This monthly newsletter gives an overview of the work and achievements during the last month by the OpenNebula project and its community.

The Santa Clara’s TechDay is around the corner. If you are in the area by the end of August, do not miss the chance to register.

Technology

The team is working on the roadmap definition for OpenNebula 5.8. Yes! You read it right. 5.6 has been just recently taken out of the oven, but 5.8 is already on the works. There is still time to influence the roadmap, so please feel free to steer towards our development page in GitHub and let us know about which cool features we can add to your favourite cloud management platform.

After the recent release of vOneCloud 3.0.7, the team is also working on a new version of vOneCloud (3.2), based on OpenNebula ‘Blue Flash’ 5.6.0, to bring the innovations in the vCenter driver to vOneCloud: stability and performance improvements, new features like a extended multi cluster support or a redesigned importation workflow with new Sunstone tabs.

In case you haven’t heard, AWS now offers a bare metal service as another choice of EC2 instances. This condition enables you to leverage the highly scalable and available AWS public cloud infrastructure in order to deploy your own Private Cloud platform based on full virtualization. We’ve prepared a post describing in high detail how can you deploy an OpenNebula instance in AWS bare metal to build a private cloud on a public cloud provider.

During the last months we have been working on a new internal project to enable disaggregated private clouds. The next OpenNebula release will bring the tools and methods needed to grow your private cloud infrastructure with physical resources from bare-metal cloud, initially individual hosts but eventually complete clusters, running on a remote bare-metal cloud providers.

Community

It appears that not everyone is in the beach this past month of July. The OpenNebula community is engaged and vibrant as ever, let us highlight a few examples.

Our friends at Nordeus agrees with us that OpenNebula and Ansible are a match made in heaven. See this blog post on how they manage their virtual infrastructure with Ansible modules that talk with OpenNebula. Delicious!

And now for a reisited blast from the past. This article describes a vulnerability in OpenNebula which has been fixed a while back, it is a very interesting security read. Also, it describes OpenNebula in a very to the point paragraph, which we would like to highlight further.

By relying on standard Linux tools as far as possible, OpenNebula reaches a high level of customizability and flexibility in hypervisors, storage systems, and network infrastructures.

We love community feedback. The critical one because it makes us improve further. And the good one, because it makes us blush, like this tweet about a smooth upgrade to 5.6. Smooth upgrade is our sign of identity!

Well, almost. We have released OpenNebula ‘Blue Flash’ Release Candidate which is just one step from being completely ready. You know we like to do things right even if it takes a bit longer. You can help us downloading this RC version, testing and reporting issues through our GitHub project or our community forum.

The OpenNebula team is now set to bug-fixing mode. Note that this is a Release Candidate aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release.

Of course we didn’t forget about our stable release OpenNebula 5.4 for which we have uploaded a maintenance release 5.4.13 including all the bug fixes from previous hotfix packages. You can download this built packages here.

Moreover we got some bugs solved in our latests hotfix updates OpenNebula 5.4.14 and 5.4.15

You know we, at OpenNebula, love to make your life easier, that is why we are so excited to present you the new oneprivision tool. Yes, as you might have guessed, this will make your host provisioning much quicker and easier. By just running a few commands you will be able to have a complete bare-metal host configured and running perfectly integrated with your cloud front-end. Our engineering team has tested this tool with Packet bare-metal servers and it works as a charm!

You can read everything about this new provisioning tool thanks to Alejandro Huertas, who has written this article containing a description and a how-to-use guide.

Community

It is impressive to be almost in July with the summer started and see how some of you are still working on bringing some great features to OpenNebula, instead of having a relaxing bath on the freshwater by the sea. We truly appreciate ;)

Before listing all the contributions of the community I would like to remind you that, until the day we release the stable version of OpenNebula 5.6, you still have time to help with the translations. So if you want OpenNebula to speak your language, contribute through this link. Contributions of any size are welcomed so don’t be shy.

To start with, we want to let you know that you now dispose of the latest Devuan ASCII free guest images ready to import in your OpenNebula infrastructures. You can check this neat tutorial for details on where to download and an installation guide.

Having new technologies integrated with OpenNebula is one of the biggest pleasures for the OpenNebula Team, this is why we are very excited to present the new TM driver developed by our colleagues at LizardFS. With this driver OpenNebula and LizardFS storage ar fully blended. For further information visit the following link.

Next, we would like to thanks @bestopensource for their great job on promoting open source projects like OpenNebula. This week they reminded all OpenNebula administrators that they can use this collection of scripts created by one of our most experienced and active users. Find these scripts here.

Also in Twitter Lorenzo Faleschini, CTO at NodeWeaver points out the easiness of working with OpenNebula:

 

Playing around with @nodeweaver at @HigecoSrl.
Devs are enjoying the ability to boot entire infrastructures to test their stack with a couple of clicks.
@opennebula Flow Happiness is in the air.

 

Outreach

Still a long way to the OpenNebulaConf 2018, however, we keep working on the organization to get interesting talks regarding open source projects and OpenNebula use cases in real world scenarios. Remember that if you register before the 15th of September you will have a 20% discount!

We know some of you can’t wait until November to see us but do not worry, we will be present in many events this summer.

If you live in the US this is your lucky summer. First you will be able to visit us at the VMworld US in Las Vegas on the 26-30th of August and then we will be present at Santa Clara’s OpenNebula TechDay hosted by Hitachi in their headquarters on the 30th of August. This TechDay is costless so feel free to register here and join us. Visit the event’s website to get all the information related.

Of course, as every year, we will have a booth at VMworld EU 2018 that will be held on the 5-8th of November in Barcelona presenting some of the greatest advances coming in OpenNebula Blue Flash.

We have some other events coming in between like Frankfurt TechDay hosted by LINBIT. Check out our official agenda to see more events and updates.

Okay, enough talk-shop!

I want to grasp this newsletter to wish you all, happy and long holidays. See you next month, with a nicer tan I hope ;)

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.

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.

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.

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!

The OpenNebula team wishes happiness and prosperity in 2018 to you and your loved ones!

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
