Our newsletter contains the highlights of the OpenNebula project and its Community throughout the month.

Technology

This month the team released vOneCloud version 3.2.1, which is based on OpenNebula 5.6.1, and as such, it includes all the bug fixes and functionalities introduced in 5.6.1

A few examples include:

  • Order of elements in list API calls can be selected (ascending or descending).
  • XMLRPC calls can report the client IP and PORT.
  • New quotas for VMS allow you to configure limits for VMs “running”.
  • The Virtual Machines that are associated to a Virtual Router have all actions allowed except nic-attach/dettach.

For more details of what is included in vOneCloud 3.2.1, check the Release Notes.

There are several other items “in the oven”, getting ready for release.  Here are a few:

  • We’ve been working on making Virtual Network self-provisioning easier, by allowing end-users to create their own networks from pre-defined network templates.
  • We are making continued progress on the LXD drivers, and getting them in shape for version 5.8.
  • Very soon vCenter users will be able to download any appliance from the Marketplace. OpenNebula datastore drivers will take care of any image conversion required.
  • Lastly, King has “Funded a Feature” through our FaF program – this one allowing Virtual Machines to define automatic network selection for their NICs. The scheduler will pick the best Virtual Network at deployment time. This will simplify the VM Template management, as it will reduce the overall number of templates needed.

Community

Across the OpenNebula User Community, we continue to see interesting and important conversation and discussion.

Leboncoin posted a thorough overview on their own blog of their infrastructure needs – including High Availability and Production stability – along with details on how their choice of using OpenNebula has helped them to successfully build and manage their own IaaS environment.  Take a moment to read the article.

“[The] OpenNebula community is also particularly active and new features are coming out regularly.”

Nodeweaver posted that they have an update being prepared to allow for single-click deployment of their Terraformer VM which integrates Ansible and Terraform to manage OpenNebula resources.  Along with this, in the near future, expect to see the VM available for use in the OpenNebula Marketplace.

LINBIT has been working on a new storage driver that integrates LINSTOR with OpenNebula. Some of the features are:

  • Deploy disk images to storage nodes automatically, or on selected nodes.
  • Attach images to hosts over the network.
  • Easy deployment of highly available images.
  • Allows live migration of VMs, even using the ssh system datastore transfer manager

LINBIT will be leading the effort to create this as an OpenNebula Add-On, so “keep your eyes peeled”.

Though more generic, here’s a quick reference to an interesting article about the ongoing transformation of Data Centers.

And lastly, as we communicated late in September, OpenNebula released an initial prototype, (with source code and packages available at the OpenNebula GitHub), for Host Provisioning.  We continue to develop this set of capabilities. In the meantime, we published a Blog post reviewing a practical exercise we carried out using this Host Provisioning feature to demonstrate its value as the case for Edge Computing continues to grow.

Outreach

October is a long month, and we have been busy, but mostly with our sights set on November! We’ve put in a great amount of planning into this year’s OpenNebula Conference 2018, which is scheduled for November 12-13 in Amsterdam.  We have a great agenda of speakers lined up, with Hands-on tutorials, and plenty of opportunity to network, share, and discuss with experts and practitioners in the cloud community.  We look forward to seeing many of you in Amsterdam. For those who cannot attend, we will be providing updates, presentation documents, and videos from the #OpenNebulaConf.

In addition, OpenNebula will be attending the VMworld Europe Conference in Barcelona from November 5-8.  We’ll be there ready to showcase OpenNebula’s integration with VMware Cloud on AWS, along with the new features of both OpenNebula 5.6 and vOneCloud 3.2.1.  Be sure to swing by booth #E422!

Soon enough, 2019 will be here.  Start thinking about hosting an OpenNebula TechDay!

We’ll see you in November! Stay Connected!

Our monthly newsletter contains the major achievements of the OpenNebula project and its community during the month of September 2018.

Technology

This month the team released OpenNebula 5.6.1 – a new maintenance release of the 5.6 “Blue Flash” series, which addresses several bug fixes, as well as incorporating various feature enhancements.  A few examples include:

  • List subcommands use pagination when in an interactive shell.
  • Order of elements in list API calls can be selected.
  • XMLRPC calls report the client IP and PORT
  • New quotas for VMS allows to configure limits for running VMs “running”.
  • Update Host hook triggers to include all possible states.
  • ‘onezone set’ should allow temporary zone changes.
  • VMs associated to a Virtual Router now feature all lifecycle actions.

OpenNebula 5.6.1 is the first version which includes “Enterprise Add-ons”, which are extended capabilities available for customers of OpenNebula Systems with an active support subscription.

For more details of what is included in OpenNebula 5.6.1, check the Release Notes.

We also closed out the month with the Release of our Host Provisioning Prototype!  This is a project on which we have been working in order to bring additional flexibility and improved efficiency to data center configurations. And it’s just the first step in OpenNebula’s focus to support the deployment of Edge Computing environments.  You can review here the details surrounding this “oneProvision” prototype.

We continue to move ahead with OpenNebula 5.8.  One of the key features that will be included in this upcoming version is OpenNebula’s support for managing LXD containers (Operating System-level Virtualization).  Some of the details and key benefits are outlined in this earlier post.

For vOneCloud, we are currently working on vOne 3.2.1, which will incorporate the same functionalities and advances which we included in our release of OpenNebula 5.6.1.

Lastly, our push for completeness and flexibility continues to grow as we focus on incorporating Python binding, (in addition to Ruby and Java) within OpenNebula.

Community

This section is where we, at OpenNebula, get most excited!  As we all continue to work and focus on bringing real value to the market through the OpenNebula platform, one of the key goals we maintain is to foster genuine interest and engagement amongst our Community.  So much of what are able to achieve depends on you, the OpenNebula users and contributors. So when we see involvement and commitment across the Community, we know that the OpenNebula project is bound for continued growth.

For example, check out this great blog contribution by Inoreader, outlining their step-by-step evolution from a Bare-Metal server architecture to completely virtualizing their infrastructure using OpenNebula and KVM for virtualization, along with StorPool for storage.

Simon Haly, the CEO of LizardFS published a brief about their collaboration with Nodeweaver to create a plugin “scale [your] OpenNebula cloud to Petabytes and beyond.” https://www.prurgent.com/2018-09-18/pressrelease447786.htm

Additionally, in a tweet earlier this month – both simple and direct – LINBIT highlighted the ease with which one can use the OpenNebula image driver,…and then posted a video demo.

The image driver for @opennebula makes #DRBD volumes easily to place VMs on.

Even beyond the direct impacts of our code, many contributors from the OpenNebula Community provided feedback and insight into a recent European Union publication on how to bring Standards and the Open Source community closer together.

And lastly, in the Community space, OpenNebula introduced Michael Abdou, their new Community and Customer Success Manager…read here.

Outreach

In the last week of September, we collaborated with LINBIT as they hosted an OpenNebula TechDay in Frankfurt, Germany!  In addition to offering a FREE Hands-on Tutorial of OpenNebula, we saw presentations and demos carried out by LINBIT, Mellanox, and Hystax.  Here you can check out how things fared at the Frankfurt TechDay.

Keep an eye out for upcoming TechDays, as we try to schedule these sessions periodically throughout the year, in various locations – all free of charge. Or even partner with us to host one of your own!!  OpenNebula TechDay info.

Don’t forget!  The OpenNebula Conference 2018 is right around the corner.  On November 12-13 we will be in Amsterdam, and there will be plenty of which you can take advantage!  From Hands-on Tutorials and Keynotes to Lightning Talks and Community discussions. Take a look at the agenda – plan on joining us in Amsterdam!  http://2018.opennebulaconf.com/

Join our Sponsor Program and be sure to maximize your benefits from the Conference.  The OpenNebula Conference 2018 is currently sponsored by StorPool, LINBIT and NTS as Platinum Sponsors and Virtual Cable SLU and ROOT as Silver Sponsors.  We would love to see you be a part of our team of sponsors!

One more item to put on your calendar is VMworld in Barcelona, on November 5-8, 2018.  We will be there with an exhibit for all things OpenNebula and vOneCloud.  Make sure to swing by booth E422!

More to come in October!!  Stay connected!

Our monthly newsletter contains the major achievements of the OpenNebula project and its community this August.

Technology

The team is working to release a new maintenance release of Blue Flash shortly, version 5.6.1. It includes several bugfixes as well as non disruptive minor enhancements like revisited quota categories for running and total VMs. Included in the bugfixes comes a new way of handling the DB upgrades so different encodings do not break the final OpenNebula install. Stay tuned!

Also, 5.8 roadmap is getting shape. One of the novelties will be support for a new container technology. This is still work in progress, so we’ll disclose it in the next newsletter (or before if you are up to date in our development portal). How’s that for a cliffhanger?

We are proud to be among the first batch of technologies which are ready to manage VMware clouds on AWS, in their new shiny service. Check out more in our blog.

A new version of vOneCloud, 3.2, has been released this month. vOneCloud 3.2 is powered by OpenNebula 5.6 ‘Blue Flash’, and, as such, includes functionality presents in Blue Flash relevant to vOneCloud, like a revamped import mechanism, overall driver performance, VNC options for Wild VMs, network creation reworked, migrate VMs between clusters, marketplace (this one is a biggie!), Docker integration,Schedule periodic actions, and more. If you have a vSphere infrastructure, and you want to turn it into a multi-tenant private cloud, with a slick self-service provisioning portal, give it a try!

Community

It is always pleasant to see how people from the community are engaged during these summer months. We want to give a shout out and two big thumbs up to everyone that helps newcomers to OpenNebula in the community support forum! This greatly helps the project.

A report by the European Union on open source and standards is bound to talk about OpenNebula, and this one indeed does. Is worth reading it to see the scope of your favorite CMP project.

OpenNebula was designed to be Cloud-API agnostic. It provides Cloud consumers with choice of interfaces, from open Cloud to de-facto standards. OpenNebula does not try to reinvent the wheel and implements existing standards when available.

Also about standards, we are very proud that OpenNebula is the first reference implementation of the OCCI cloud computing API standard.

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!

Technology

OpenNebula 5.6 is here!!

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 ;)

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.

Last month we have been working on solving all the reported issues and “voilá!” we brought three hotfix releases for you.

OpenNebula 5.4.10 brought vOneCloud 3.0.6, which includes all the bug fixes and functionalities. Check this post for helpful links and further information. Find all the improvements and changelog on the Release Notes in our documentation site.

I know you are all anxious about the next major release OpenNebula 5.6, so again this month I will personally leak some of the new features coming, don’t tell anyone ;)

Cloud view changes, for the better of course. End-users will be able to see and control their quotas in real time. Surely your users will love to have all this information and keep a real time control of their resources.

As mentioned in past newsletters, the new amazing dashboard is faster and nicer, and this could only be possible with the integration of the latest Font Awesome libraries. We know many of the designers will love to play around with this new update.

Last one, KVM and vCenter will be more united than ever! In the new OpenNebula you will be able to control your hypervisors under the same view.

Stay tuned, probably for next month you will be able to read all about OpenNebula 5.6

Community

Lets go and start a quick review on the activity of our community. This section will go through all the actions concerning OpenNebula and community interests. Keep reading.

Get your cloud up and running with this detailed tutorial written by Jonathan Philipos and published at Packet.net. In this tutorial you will learn how to build your cloud on fast and secure servers provided by Packet. We have already follow this tutorial step by step and it was so nice and simple that even we were surprised about the greatness of this synergy!. Find this tutorial here and delight yourself.

Again our active partners from CSUC have made an interesting report on the OpenNebula provider for terraform developed by Runtastic team. Not only this, they have also a great tutorial explaining how to deploy kubernetes cluster on OpenNebula, in a fully automated way with Terraform and Ansible.

Even more! They have another tutorial about how to deploy Docker machines in OpenNebula using the docker-machine driver. We would like to propose a big toast to this amazing work, cheers!

 

Impressive achievement coming from Carlo Daffara, one of the most respected members of OpenNebula’s community. Via twitter he has proved to have a soft-realtime scheduling engine, which will guarantee a percentage of CPU to a KVM over some range of time. As he states on the tweet:

“Will make quite an interesting option for industrial control systems”

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.

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.

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.
