OpenNebula Integrates with Azure to Build Hybrid Clouds

Today we are sharing exciting news about the expansion of the number of public clouds supported by OpenNebula to build hybrid cloud deployments. As a result of the collaboration between OpenNebula and Microsoft, a new set of plug-ins to support Microsoft Azure has been included in OpenNebula. This partnership has been announced today by Microsoft Open Technologies at the O’Reilly Open Source Convention (OSCON).

“With this set of plug-ins, IT pros and system integrations can use OpenNebula’s rich set of infrastructure management tools to manage cloud deployments across Microsoft’s private, public and hosted cloud platforms.”

The Beta version of  OpenNebula 4.8 bringing the new drivers was released today and is available for testing. The integration has been carried out using the Microsoft Azure SDK for Ruby, which interacts with the Azure REST API, enabling a complete control of the lifecycle of Virtual Machines in a transparent way within an OpenNebula cloud. Thanks to these new plug-ins, private resources can be easily supplemented with resources from Azure to meet fluctuating demands.

So far the only public cloud officially supported by OpenNebula to build hybrid cloud deployments was Amazon AWS. Supporting multiple public cloud providers opens the possibility of defining pre-determined schedule or performance-based policies for the execution of applications in different clouds, that can be fine tuned to achieve an optimal placement in terms of performance and cost. This new support also enables the ability to meet services constraints regarding special functionality offered by a subset of the supported public cloud providers, like for instance high availability.

Need more information? You are welcome to use the OpenNebula community instruments to ask around (for instance, the users mailing list is a good place to pose your questions).

As always, we value your feedback and contributions to this new feature!

OpenNebula 4.8 beta released!

The OpenNebula team is really happy to release the first beta for version 4.8 (4.7.80). In this version, alongside several fixes, we have been working on some new features:

  • Improvements to the Cloud View interface like OneFlow integration
  • New VDC admin view that matches the Cloud View.
  • New virtual network model that make its configuration and management more flexible with address ranges.
  • IP reservation.
  • Network interface default configuration
  • Quotas can now specify a value of 0 to disable certain objects for users or groups.
  • Logs now have the zone ID so its easier to parse in a centralized syslog configuration.
  • New datastore to use local block devices.
  • Inter datastore image clone.
  • Support for RBD format 2 in CEPH drivers
  • IO throttling for disk devices.
  • New hybrid drivers for Microsoft Azure and IBM Softlayer services.
  • OneGate can now be used to get information about all the VMs in a service.
  • OneFlow can wait until a VM phones home before starting the rest of VMs.
  • Network configuration in a flow can be specified per role.
  • User input on template instantiation for certain VM parameters.
  • Default view for a group in Sunstone.
  • Instantiate VMs on hold.
  • Boot order can be selected from Sunstone.

You can find more information about the new features in the release notes.

In this new release we also start supporting RHEL/CentOS 7. We encourage everyone that is using or planning to use this distributions to try the new packages and fill any bugs found in them.

We have also created new repositories for this release so its easier to install and your 4.6 installations don’t upgrade automatically to it.

You can download the packages from the software page or use the new repositories. Now is the time to try it and fill bugs so we can fix them before the final release.

This new release code name is “Lemon Slice“. From Wikipedia:


The Lemon slice nebula, also known as IC 3568, is a planetary nebula that is 1.3 kiloparsecs (4500 ly) away from Earth in the constellation of Camelopardalis (just 7.5 degrees from Polaris). It is a relatively young nebula and has a core diameter of only about 0.4 light years. The Lemon slice nebula is one of the most simple nebulae known, with an almost perfectly spherical morphology. It appears very similar to a lemon, for which it is named. The core of the nebula does not have a distinctly visible structure in formation and is mostly composed of ionized helium. The central star is a very hot and bright asymptotic red giant, and can be seen as a red-orange hue in an amateur’s telescope. A faint halo of interstellar dust surrounds the nebula.

Thank you all for the input, patches and bug reports that made this release possible.

OpenNebula Newsletter – June 2014

We want to let you know about what we are up to with the main news from the last month regarding the OpenNebula project, including what you can expect in the following months.

We have created a new user survey that will take you only 5 minutes to complete. As an open-source community, it is very important for us to have information about your deployment. Doing so you will have influence over the project and software direction, and will help us improve the support for most demanded infrastructure platforms and configurations.


OpenNebula 4.8 is steadily approaching the feature freeze phase, to start the certification process. The OpenNebula team is pretty serious about delivering a beta version of your favourite Cloud Management Platform in a couple of weeks!

This release will polish past features as well as address those left aside in OpenNebula 4.6 Carina. The main focus is twofold. On the one hand, OpenNebula 4.8 is going to address simplicity. OpenNebula is already by far in a unique position among its peers in simplicity: simple to install, simple to configure, simple to use. It is indeed one of the design principles behind OpenNebula, as explained in this post about the OpenNebula vision. The team is decided to keep this simplicity and to extend it. A good example of this is the extension of the Cloud Admin view, with support now for vDC administrators (see below a sneak peek), intended to make Virtual Datacenters easy to manage and consume. Check out the complete list of issues the team is working on for this upcoming release.


On the other hand, OpenNebula 4.8 will bring an important improvement to the hybrid model. Aside from the possibility to outsource VMs to Amazon EC2, this new release will bring the ability to manage VMs in both IBM SoftLayer and Microsoft Azure. We are excited to be collaborating with these two great companies. You can check here the announcement in the SoftLayer blog of the integration, and here is the branch with the prototype integration. The same plan applies to Microsoft Azure, a partnership will be announced soon and a prototype’s code is already in the OpenNebula repository.

Also, and as part of our commitment with the latest stable version, OpenNebula 4.6.2 was released. This release comes with several bug fixes found after the latest release, the one worth highlighting being the security vulnerability in Sunstone. Thanks to Dennis Felsch and Mario Hei­de­rich from Horst Görtz Institute for IT-Security, Ruhr-University Bochum for telling us about it. You should upgrade your installation to prevent unauthorised access.

Last, but by far not least, we wanted to point the benefits of running OpenNebula versus vCloud. So if you are evaluating both alternatives to manage your infrastructure, we are sure you will find this post an interesting read. In a nutshell, using OpenNebula leverages existing VMware infrastructure, protecting IT investments, and at the same time avoids future vendor lock-in, strengthening the negotiating position of the enterprise.


Feedback from the community has proven to be critical, specially this last month thanks to the vulnerability discovered by folks at Horst Görtz Institute for IT-Security, Ruhr-University Bochum. This feedback was crucial in releasing OpenNebula 4.6.2.

The community also excels at providing new and better ways to manage an OpenNebula cloud. This past month, a new plugin for Knife (a command-line tool that provides an interface between a local chef-repo and the Chef server) was released by our friends at Megam.

OpenNebula is proving steadily as a very good solution for hosting infrastructures. We traveled to Zagreb, Croatia, to be part of the presentation of the new OpenNebula cloud built by AVALON hosting. A fine press release with the CEO of Avalon, the IBM director of Croatia, and Microsoft MVPs, as well as members of the OpenNebula team. Also, folks from HostColor have announced this past month a new datacenter in Indiana running OpenNebula.

It is very important to keep the add-ons catalog up to date, that’s why we deeply appreciate keeping them working with the latest versions of OpenNebula, like David Macleod did this month with the Infiniband (SR-IOV devices) support.

It is very pleasing as well to see that OpenNebula goes a long way into cloud computing research. Guys at MIMOS, the Malaysian national R&D center, are basing their cloud infrastructure in OpenNebula, using Ceph as the storage backend.

We are very proud of the OpenNebula community, as well as very happy to see that is a very healthy and supportive one, as proven by it’s ever growing population.


As usual, first things first, this year’s OpenNebula Conference will be held in Berlin as well, 2-4 of December, 2014. If you want to repeat or find out how it is for yourself, save the date! The Call for Papers and early registration prices are open until the 15th of July, don’t say we didn’t told you!

Last month we organised two successful OpenNebula TechDays in both US coasts. We had the chance to share new features of OpenNebula 4.6 with the attendees and have them build a fully working private cloud in just a matter of hours, as well as interesting talks, ranging from PaaS solutions based on OpenNebula: Megam – Cloud orchestrator for OpenNebula, open hardware initiatives which are a great match for OpenNebula: OCP Open Rack, the renowned distributed object-store: Ceph for Cloud and Virtualization environments and more use cases. We want to give a big thanks to the hosts: TransUnion|TLOxp and Hyve Solutions for their amazing hospitality, organization and making these events a success! Upcoming TechDays include Timisoara in September and Barcelona in October, and they will be collocated with the CentOS Dojo.

Check out the OpenNebula presentation given this last month by Martin Alfke in the Hamburg German Unix User Group. Moreover, if you are fluent in German, do not miss the The Foreman and OpenNebula webinar given by Netways. Moreover, do not miss the talk given by our Project Director at Berkeley Lab, on bringing bringing private clouds to HPC environments with OpenNebula.

Members of the OpenNebula team were also present in the GigaOM: Structure 2014 in San Francisco, as well as the HostingCon 2014 in Florida.

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.

Aftermath of the TechDays in Florida and Bay Area

We have had a great time in OpenNebula Cloud TechDays of the past weeks:

We had the chance to share the new features in OpenNebula 4.6 and the upcoming releases with all the attendess and have them build a fully working private cloud in just a matter of hours. Cloud computing has never been this easy!

But that’s not everything, we had really interesting talks, ranging from PaaS solutions based on OpenNebula: Megam – Cloud orchestrator for OpenNebula, open hardware iniciatives which are a great match for OpenNebula: OCP Open Rack, the renowned distributed object-store: Ceph for Cloud and Virtualization environments and more use cases.

So a big thank you all, for coming and attending the event, for your great feedback and excitement.

And of course big thanks to the hosts: TransUnion|TLOxp and Hyve Solutions for their amazing hospitality, organization and making these events a success!

AVALON – Why OpenNebula is an Excellent Fit in Hosting

Damir Mujic, founder of AVALON web hosting

Damir Mujic, founder and CEO at AVALON web hosting

As a company that has been in the hosting business for the past 17 years, Avalon has always had only one goal – to provide the best possible service to our customers. We are a premium web hosting provider and we are one of the largest providers in Croatia and the region, hosting more than 16,000 domains across Europe.

Two years ago, we decided to build our web hosting platform entirely from scratch, using the best cloud technology that we could find. While searching for partners, it was extremely important for us to find the best among them and apply the best of their technologies enabling us to provide a premium level service to our customers..

We selected the IBM as a hardware vendor and became the IBM Managed Solutions Provider, building a complete infrastructure on the IBM System x technology. As almost 80% of our customers are using Linux hosting our perfect match was combination of CentOS Linux and KVM hypervisor.

When considering cloud management solutions, we tried many well-known open source and some commercial cloud solutions, and after thorough testing we decided to choose OpenNebula as our foundation platform for future development of our cloud hosting services.

We developed our OpenNebula cloud integration with Ceph, a distributed object store and file system which we found really impressive.  – Today, that is the platform for our shared hosting and virtual server users, and we have over 6 month experience in production.

We believe that OpenNebula with EC2 API support together with Ceph Storage, which is compatible with the S3 object storage, is a very good basis for the further development of our web hosting services, as well as many other services in the future based cloud technology.

Next week in Zagreb, Croatia, on July 3rd at 10 AM, we are organising a press conference where the official launch of our hybrid cloud platform will be announced. I am very grateful to OpenNebula founders Mr. Ignacio M. Llorente and Mr. Rubén S. Montero, who are supporting us in this project, and we are extremely pleased that Mr. Constantion Vasquez, as a Senior Infrastructure Architect at C12G Labs, will attend as a speaker at the conference, introducing OpenNebula project to the Croatian media.

In addition to Mr. Vázquez and myself, other conference speakers will include Mr. Damir Zec, managing director of IBM Croatia, Mr. Dobrisa Adamec, Microsoft MVP and Mr. Tomislav Bronzin, Microsoft MVP who will cover the second smaller part of our platform targeted at  ASP.NET developers.


About Simplicity, Openness, Reliability and Flexibility in Private Cloud Computing

We feel it’s time to remind our vision of a world that won’t be dominated by a single cloud management platform. We’re moving into a world of open cloud — where each organization can find the right cloud for its unique needs. A single cloud management platform can not be all things to all people, there will be a cloud space with several offerings focused on different environments and/or industries. This is the natural evolution, same happened in other markets like relational databases or the web servers.

Our commitment to the open cloud flows directly out of our mission — to become the simplest cloud enabling platform — and our purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure, where:

Simplicity means …

… you do not need an army of administrators to build and maintain your cloud.

Openness means …

… you will run production-ready software that is fully open-source without proprietary extensions that lock you in.

Reliability means …

… your cloud will run for years with little maintain.

Flexibility means …

… you can easily build a cloud to fit into your data center and policies.


Looking for Alternatives to vCloud for your VMware Infrastructure?

Many companies contact us because they are looking for alternatives to VMware vCloud. They usually report that:

  • vCloud is not an easy to use solution
  • vCloud is mostly suited for vSphere and public clouds running VMware
  • vCloud can no be adapted to their needs
  • Last, but not least, VMware announced in september 2013 that vCloud Director was approaching end of life for enterprises with its functionality being split into vCenter and vCloud Automation Center

Because it is completely hypervisor agnostic, fully supports VMware, and is easy to install, maintain and use within existing VMware environments, OpenNebula is widely used as an open alternative to VMware vCloud at significantly lower costs. Some of our users also see OpenNebula as a migration tool that allows them to perform a smooth transition from VMware to more open hypervisor alternatives like KVM. In other words OpenNebula leverages existing VMware infrastructure, protecting IT investments, and at the same time avoids future vendor lock-in, strengthening the negotiating position of the enterprise.

Companies usually evaluate other alternatives, like some of the OpenStack-based products, Red Hat’s mainly. In these cases, we suggest the company to:

  • Compare features and see which product is closer to vCloud in terms of enterprise cloud features
  • Ask the other providers if they offer enterprise support for both VMware and KVM (or any other open-source hypervisor)
  • Check if the other products are really open-source or a proprietary extension of a open-source software

Finally, companies need to develop a hybrid cloud strategy. We understand private cloud as a complement to public cloud, and this is why we provide unique features to build hybrid cloud deployments. OpenNebula offers a single management interface for internal and remote cloud resources.

So before starting the migration from vCloud to vCAC, why do not you give a try to OpenNebula to manage your cloud platform?. Our community is willing to help you.
