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

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

We look forward to seeing you in Madrid!

Announcing the OpenNebula Champion Program

We would like to officially announce the OpenNebula Champion program. If you attended our last Conference, you’re probably aware that for the past couple of months, we’ve been designing a program for our community members who are interested in becoming Champions for OpenNebula around the world.

Champions are passionate volunteers who work to connect, teach and spread OpenNebula. They represent OpenNebula and help to teach and spread OpenNebula, throughout the world. In the project web site you have complete information what the program entails, how the project is planning to support its Champions and how to become an OpenNebula champion.

This is the list of the first ever Champions of the OpenNebula project:

champions

During the last years we have traveled all over the world delivering talks and hands-on workshops and organizing TechDays and Tutorials, where we have met a lot of amazing, enthusiastic, resourceful and engaged people. In order to continue with our journey, in a few days we will announce the schedule of OpenNebula Conferences, TechDays and Training for 2017. These events provide a great opportunity to raise awareness for the project and get more of you involved as contributors and users. As we scale the project to the next level, we need your help in spreading the message.

We look forward to your participation, and we would like to heartily thank our Champions and TechDay hosts!

New Contextualization Packages

We are happy to announce new versions of the OpenNebula contextualization packages for Linux (ver. 5.0.3) and Windows (ver. 5.2.0). For Linux, this is mainly a bugfix release with 2 significant improvements. For Windows, this is a very first release, newly distributed as the MSI package.

Linux contextualization contains following changes:

  • User $USERNAME is created, if missing. The user password can be also Base64 encoded in context. variables $CRYPTED_PASSWORD_BASE64 or $PASSWORD_BASE64. Race condition has been also fixed to create the $USERNAME first and contextualize the SSH access later.
  • Refactored code is used to set host and domain names (via $SET_HOSTNAME or $DNS_HOSTNAME context. variables) in a more standard way. Platform dependent scripts were replaced by single unified script. Also, the hostname entry in a local static lookup table (/etc/hosts) is created and even updated on the IP configuration change (PR). Big thanks to Florian Heigl for designing the change request and time spent in testing.
  • Jan Kasprzak provided a patch (PR) for the Red Hat-like systems to disable IPv6 autoconfiguration and by default enable the dual-stack on configured interfaces. This behavior was also fixed for Debian-like systems (PR).
  • C. R. Oldham provided a patch to support growroot with Btrfs (PR).
  • A race condition in run locking was fixed (PR)

Windows contextualization scripts are distributed newly as the MSI package. The source codes archive is still available in case you experience any problems with the package or want to use your own way how to manage the scripts. The package can be installed by double-clicking on the downloaded package icon or from the command line:

msiexec /i one-context-5.2.0.msi

Windows contextualization is started as the Windows service named onecontext (under rhsrvany wrapper). Please remove any existing contextualization (and its startup mechanism) from your virtual machine before installing this package.

You can download the Linux and Windows packages here. Packages are compatible with the OpenNebula versions from 4.6 to 5.2.

OpenNebula 2016: Year in Review

christmas_one_2016We are approaching the end of this year 2016, winter has finally come, and we wish to thank all those individuals and companies that helped with the numerous achievements of OpenNebula throughout the year.

OpenNebula is keeping its momentum, widening its adoption and turning into a very mature product, with more than  9 years of development behind. We like to give a special recognition to the over 1.000 contributors registered in the development portal, who help advance OpenNebula by submitting bug fixes, patches, feature requests, …. We look forward to your contributions to code development!.

Also, we would like to thank Blackberry,  Unity and the Université Catholique de Louvain for funding general interest features that are made available publicly in OpenNebula releases through the Fund a Feature program. The community is certainly in debt with you.

It is always difficult for an open-source project to know who uses its software. So we consider ourselves lucky to know that there are more than 3.500 production OpenNebula clouds connected to our marketplace, with the largest one spanning over 16 data centers with over 300.000 cores. This year a milestone was achieved with more than 180.000 downloads of the OpenNebula packages.

Two major OpenNebula releases were published this year: 5.0 Wizard and 5.2 Excession. Moreover, three maintenance versions were released to fix bugs and polish features. Focus in future release will be centered in the vCenter integration, without neglecting the default hypervisor for OpenNebula clouds, KVM. The plan is to bring vCenter up to speed with the KVM support.

vOneCloud achieved v2.0 this year, an important milestone that allowed to settle a number of features and plan for the future roadmap. Lots of new vCenter related features are present in OpenNebula and will make their way to vOneCloud, specially with the redesign expected in OpenNebula 5.4 of the vCenter integration, that will bring full storage and network manage to the table. vOneCloud exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers and a slick self-service portal.

The community has been very active engaged this year 2016. Many contributions in the form of new addons, functionality patches, feedback for future releases, messages in the forum, twitter and so on were delivered in the past 12 months.  You can check these contributions, along with other details about the great progress that we have seen for the OpenNebula project in our monthly newsletters. We are also announcing our new Community Champions Program. An exclusive group of passionate technology and community leaders that help sustain and grow our user base. They represent OpenNebula and work to connect, teach and spread OpenNebula, throughout the world.

This year’s OpenNebulaConf was held again in in Barcelona and featured very interesting keynotes by relevant users like Telefonica or Akamai, among others. It featured three days packed with interesting talks and great experiences exchange. It was a great success thanks to the support and participation of all of our community members, speakers, sponsors and friends. You can check our YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference.  For 2017 we are planning to break down the conference in two instances, one to be held in Europe and another in the US. Yes, our first conference in the US. Stay tuned!

Also this year, members of the OpenNebula team participated in several OpenNebula TechDays around the world. These are full day events to learn about OpenNebula with a hands-on cloud installation and operation workshop and presentations from community. We want to give a warm thank you to all organizations that hosted a TechDay in 2016 for their hospitality: Mimos in Kuala Lumpur, StorPool in Sofia, Rentalia in Madrid, ContainerizeThis in Dallas, C151 Data Centers in Toronto, Harvard FAS Research Computing in Cambridge, BIT.nl in Ede, Netways in Nüremberg and Trinity College Dublin in Dublin. We are organizing the schedule of TechDays for future months, send us an email or send it to the community discuss mailing list if you are interested in hosting a TechDay event.

Finally, we want to highlight the participation in both VMworld Europe and US, where the team were showcasing vOneCloud functionality over vCenter.

Community

We are very happy with the feedback given by the community. OpenNebulaConf 2016 was the perfect place to reunite with all the OpenNebula folks, and to share with them our plans for your favourite Cloud Management Platform.

For instance, we love tweets like this, it helps reminding us why we iterate OpenNebula to give users the smoothest experience.

So far we are happy with @opennebula – much more developer/admin friendly

It is also a joy to learn who is using OpenNebula to build production clouds, and how they are using them. This is a very nice example of a very useful use for an OpenNebula cloud. Having an OpenNebula cloud deployment in the European Space Agency (and, more importantly, knowing about it) is a good kick!.

We also want to give the thumbs up to those kind souls that give us a hand helping newcomers to set up their OpenNebula clouds. It is important to give a warm welcome to people willing to understand OpenNebula and approaching through the user forum, so thanks!

Outreach

If you are new to OpenNebula, one of the best ways of catching up is attending the OpenNebulaConf. You have the chance to meet OpenNebula users with real use cases and production environments, and to solve the doubts you may have about the technology to build private and hybrid clouds. If you are wondering what the OpenNebulaConf looks like, check the post with the material of 2016 OpenNebulaConf. Check out the YouTube channel, download the slides from the slideshare account or take a look to the pictures of the conference. Stay tuned for next years location and format, there will be surprises!

Besides the conference, the OpenNebula team also organize more local, one day events called the OpenNebula Cloud TechDays. These events are designed to learn about OpenNebula with a hands-on workshop on cloud installation and operation, and presentations from community members and users. We’ve opened the Call for Hosts for the TechDays in 2017, so if you are willing to host one for the local OpenNebula community, and give us a shout.

The OpenNebula team is growing at a fast pace. Are you looking to get into the cloud professionally? If you are looking to work in an agile environment to develop new features and integrations and participate in the upstream community, this is your chance. Check out the OpenNebula Systems vacancies if this is the case, we are currently interested in Cloud Developers and Community Specialists.

Remember that you can see slides and resources from past events in our Events page. We have also created a Slideshare account where you can see the slides from some of our recent presentations.

We Have Redesigned the Public MarketPlace!

The new MarketPlace is in the same place, and looks almost the same, but it’s now easier to use than ever!

marketplace

You can still see your favourite appliances from within Sunstone:

marketapps

But the good news is that the way you can contribute to the MarketPlace has changed drastically, it’s now a much simpler procedure, far more comfortable for developers. To add a new MarketPlaceApp you simply need to send us a pull request to this repo:
https://github.com/OpenNebula/marketplace

The procedure is quite intuitive and is explained in detail in the README.md of that repo, but in a nutshell you need to:

  • Fork the repo
  • Create a new folder for your company
  • Generate a uuid using uuidgen for instance
  • Create a new appliance file following the syntax explained in the README.md file. Feel free to take a look at other examples in the repo.

So if you want to contribute a new appliance, you can start by following this guide to enable OpenNebula compatibility, and then you can submit it the new MarketPlace!

Happy contributing!

OpenNebula 5.4 – Enhancements in vCenter Integration

The development of OpenNebula 5.4 has already started, and the biggest focus for this release is improving the vCenter integration. In particular, two areas will be addressed, networking and storage, in order to bring the vCenter up to speed with the open source hypervisor, KVM. After this release there will be virtually no differences between managing VMs on VMware or on KVM.

Networking

The goal in the vCenter network integration is to be able to create Networks (ie Port Groups and Distributed Port Groups) from within OpenNebula, not just consume then. We will be using the same mechanism as in KVM, ie, configuring the underlying network dynamically as required by the Virtual Machines, including the management of VLAN IDs.

 

picture1

There is a clear benefit from this new feature, as it implies a great improvement to the provisioning model. Typical use cases involves administrators creating groups of users or even VDCs on a multi-tenancy environment, where network isolation is a must. Currently, the administrators are required to create beforehand either Port Groups or Distributed vSwitches in the vCenter in order to provide tenants with isolation.

The second step is a big enterprise, which will take more than just one release to accomplish, which  is to offer this functionality directly in OneFlow, with the ability to create new networks automatically whenever a service is launched. This will allow tenants to spin up network isolated multi-vm services without further management steps in vCenter or OpenNebula.

picture2

Storage

The aim here is to improve the vCenter storage drivers to be at the same level than the KVM counterpart, enabling:

  • System Datastores
  • Non persistent images

This again is a big enterprise that will take more than one release to accomplish.

This functionality will enable important features for the vCenter integration, like for instance the ability to allow the OpenNebula scheduler to intelligently choose the target system datastore (replacing Storage DRS!), support for storage quotas, disk resize both at boot and running time, and much more!

***

The Network and Storage import process will be greatly improved. Whenever a VM Template is imported, all the NICs and DISKs of the VM Template will be imported, and associated networks, datastores and images will be created.

Additionally, improvements in the driver efficiency will ensure the scalability of OpenNebula with very large scale infrastructures. The main focus will be time and memory efficiency, mainly in the monitoring operations.

OpenNebula roadmap is strictly based on your input. Thanks for your amazing feedback!

9 Years of OpenNebula!

nine

Today is the 9th anniversary of the founding of the OpenNebula open source project. We still remember the early days of OpenNebula, when we decided to start an open-source project to grow, distribute and support the software prototypes that we developed to support our research in virtualization management on distributed infrastructures. Yet here we are, nine years later, with one of the most successful projects in the open cloud ecosystem.

OpenNebula has grown into a widely-used user-driven project, with lots of examples of production use in academia, research and industry, over 100K downloads from the project repositories in the last year, more than 1,500 clouds connected to our marketplace, and large-scale infrastructures with tens of data centers and hundreds of thousands of cores. We are very proud of this growth as the only fully-open enterprise-ready management platform to build clouds.

None of it would be possible without your help, the hard work of thousands of users and contributors!
