Only a Few Days Left for OpenNebulaConf 2014!

This edition of the conference is just around the corner, happening next 2-4 December in Berlin. If you are interested in attending the conference, we entreat you to register swiftly, since only a few seats are left.

1. An Amazing Speaker Lineup and Agenda

This year’s edition of the international OpenNebula Conference is packed with an amazing agenda. If you want to learn about Cloud Computing in general, and OpenNebula in particular. If you are familiar with the software or even an active user or contributor to the project, willing to hear and learn how other members of the community bend OpenNebula for their infrastructure needs, this is the place to be!

Take a look at the highlights from the final agenda:

2. Hacking Workshop and Hands-on Tutorial of the Brand-new OpenNebula 4.10

Besides its amazing talks, there are multiple goodies packed with the OpenNebulaConf registration. Lightning talks, a hands-on tutorial, and meeting OpenNebula users and developers are some of the treats you are in for if you are attending the conference.

One of the major benefits is the possibility to attend an OpenNebula tutorial the day before of the conference. This 3-hour tutorial is included in the registration, so everyone is welcome to attend it. The tutorial is intended for devops and system administrators interested in deploying a private cloud solution, or the integration of OpenNebula with other platforms.

For those that already master OpenNebula, we are organizing a Hacking session that is meant for people that already has OpenNebula deployed and knows how to use it. You can catch up with OpenNebula developers and have conversations that are a bit hard to have in the mailing list. It is also a great place to meet other people that may be doing similar things or have already sorted out some of the problems you may have.

3. Social Event

Right on the riverside, in a beautiful part of Berlin, you can find the old dairy farm with its historic atmosphere. You can experience the most beautiful and varied shades of nature, associated with the four seasons with them.

Last year’s conference was an absolute success, with fruity presentations of long time users of OpenNebula, and with various use cases that, we can confess, largely surprised the OpenNebula team for their artfulness. It is always a pleasure to see how people are using OpenNebula.

See you in Berlin!

OpenNebula is 7 Years Old!

Yes, time flies, and it is now time to celebrate the 7th anniversary of In the post we wrote last year to celebrate our sixth anniversary we described the progress of the project in terms of its community, adoption and innovation. We are really proud to confirm that those figures are growing at the same rate.

This year we would like to focus on our commitment to the open cloud. We think it is important to clearly state what “open”, “simple”, “scalable”, and “flexible” mean for us. Mostly because, as you well know, terms like “open-” and “open-source” are used by many vendors as a marketing tool to lock you into their own version or distribution of a hyped open-source software. Well, I think you know what we mean.

  • Openness means you can run production-ready software that is fully open-source without proprietary extensions that lock you in. Yes, this means that OpenNebula does not need enterprise extensions. Yes, OpenNebula is not a limited version of an enterprise software… There is one and only one OpenNebula distribution, and it is truly open-source, Apache licensed, and enterprise-ready. There is no fragmentation.  As recently stated by one of our users:

“Other open-source cloud management platforms do not work out of the box, you need to go through a vendor – they are open source but vendor-based and brings proprietary components”

  • Simplicity means that you do not need an army of administrators to build and maintain your cloud. OpenNebula is a product and not a toolkit of components that you have to integrate to build something functional. Moreover your cloud will run for years with little maintain. As recently stated by one of our users:

“It is easy to bring existing sysadmins to handle OpenNebula since it is just standard components that is used”

  • Flexibility means that you can easily build a cloud to fit into your data center and policies. Because no two data centers are the same, we do not think there’s a one-size-fits-all in the cloud, and we do not try to impose requirements on data center infrastructure. We try to make cloud an evolution by leveraging existing IT infrastructure, protecting your investments, and avoiding vendor lock-in. As recently stated by one of our users:

“OpenNebula captured my interest for several technical reasons besides the fact that it is truly open. It’s architecture is very elegant; it has C++ bones, ruby muscles and bash tendons. It’s extensible and understandable”

  • Scalability means that you can easily grow the size of each zone and the number of zones. Some of our main users have reported infrastructures with tens of zones distributed worldwide that have executed several hundreds of thousands of virtual machines. As recently stated by one of our users:

“Very simple to use, implement and deploy, but yet, you guys make it very scalable and reliable”

Fully embedded in our commitment to the open-source world, we are immersed in a disruptive move, building a bridge between the proprietary virtualization field dominated by VMware and the open source cloud arena. We are doing so with an integration between OpenNebula and vCenter, easy to use and to deploy, bringing cloud features on top of production virtualized infrastructures. VMware users can take a step toward liberating their stack from vendor lock-in. Being OpenNebula a platform independent software, they can gradually migrate to open virtualization platforms.

Looking back, it is inspiring the distance that we have come together. And that is nothing compared to what is planned for the future. We look forward to meeting you in a few days in Berlin in our second OpenNebula Conference, we have a lot to celebrate.

Thanks to all of you and happy anniversary!

OpenNebulaConf2014: Practical experiences with OpenNebula for cloudifying a SaaS by Deloitte’s Tim Verhoeven

Tim Verhoeven, lead architect for a Business Intelligence and Analytics SaaS cloud platform at Deloitte Consultin, will give a keynote entitled “Practical experiences with OpenNebula for cloudifying a SaaS” in the upcoming OpenNebulaConf 2014 to be held in Berlin on the 2-4 of December.

Tim will speak about how his team manages a SaaS platform for Business Intelligence and Analytics applications using a diverse set of middleware (mostly IBM). However the original setup of this platform was not done using a cloud architecture. In this talk they describe the reasons for selecting OpenNebula. The architecture of the new setup. The process of migrating to that new setup and the lessons they learned during that process and in the daily operation of the platform. And finally this talk will also cover their vision for the next step which is to move towards a hybrid cloud setup.

Tim currently works for Deloitte Consulting in Belgium as the lead architect for a Business Intelligence and Analytics SaaS cloud platform. Tim Verhoeven is been involved in IT Infrastructure for more then 10 years and in these years gathered experience with Linux, networking, servers, storage and the tools and processes to deploy, manage and monitor these infrastructures.

Building Clouds on vSphere: vOneCloud vs vCloud Competitive Pricing Review

This case study assumes you want to build a private cloud on top of an existing virtualized datacenter composed of multiple hosts running vSphere and managed by one or several instances of vCenter. It is understood that you do not want to abandon your investment in VMware by retooling the entire stack. You want to continue managing your infrastructure with already familiar and powerful VMware tools, such as vSphere and vCenter Operations Manager. Your goal is to create a self-service cloud environment on top of your vSphere infrastructure to provide your users with a simple cloud interface featuring elasticity, multi-tenancy and self-service provisioning.

This post compares the pricing of two different approaches to build this cloud environment, the deployment of vOneCloud (an open-source replacement for vCloud based on OpenNebula) on your existing vSphere/vCenter environment versus the adoption of VMware vCloud Suite:

  • The latest version of the vCloud Suite (5.8) brings all the components needed to build and manage a vSphere-based private cloud. The three product editions, Standard, Advanced and Enterprise, include vSphere Enterprise Plus and vCloud Director. According to VMware’s official price list, the average cost (including license and support) per server (2 processors) and year (license cost prorated in three years) of vCloud Standard is €4,883.41 and € 5,243.13 for basic and production support level respectively.
  • vOneCloud requires vSphere (Standard edition is enough) and vCenter Standard. According to VMware’s official price list, the average cost (including license and support) per server (2 processors) and year (license cost prorated in three years) of vSphere Standard is €1,087.35 and €1,177.27 for basic and production support level respectively. If we add the cost of vCenter Standard (we consider a cloud consisting of 10 hosts), the overall cost per server and year is €1,331.52 and €1,439.44 for basic and production support level respectively. vOneCloud is free, open-source software, and the cost of an enterprise support subscription per server and year is between €300 and €900 for basic and premium support.

This case study reveals savings of more than €3,000 per server and year using vOneCloud over vSphere/vCenter to build the cloud. This difference is much higher if you are using servers with more than 2 processors, given that VMware licensing/support costs are per processor while vOneCloud support costs are per server. For example, in infrastructures with 4-CPU servers, savings would be more than €6,000 per server and year.

vCloud defenders will argue that vCloud suite incorporates more features than vOneCloud on top of vSphere/vCenter. However the same arguments could be used in favor of vOneCloud, which offers features for hybrid cloud or federation that are not offered by the vCloud suite (your would require vRealize). In any case, the right cloud tool depends on your specific needs, our experience is that vOneCloud exceeds the cloud management requirements of most users.

The main advantage of vOneCloud is the strategic path to openness as you move beyond virtualization toward a private cloud. Adopting vOneCloud, you take a step toward liberating your stack from vendor lock-in. Being platform independent software, you can gradually migrate to other virtualization platforms. vOneCloud can leverage your existing VMware infrastructure, protecting IT investments, and at the same time avoid future vendor lock-in, strengthening the negotiating position of your company.

Why not give it a try?. The vOneCloud appliance does not interfere in existing vSphere configurations, procedures and workflows. This means that you can try it and if you decide not to adopt it, you can just delete it.

OpenNebulaConf2014: Puppet and OpenNebula by Puppet Labs’ David Lutterkort

David Lutterkort, Principal Engineer at Puppet Labs, will give a keynote entitled “Puppet and OpenNebula” in the upcoming OpenNebulaConf 2014 to be held in Berlin on the 2-4 of December.

This talk will show how Puppet can be used by adminsitrators to manage OpenNebula hosts, and by users to manage their infrastructure as well as how to use Puppet during image builds. Many facets of using an IaaS cloud like OpenNebula can be greatly simplified by using a configuration management tool such as Puppet. This includes the management of hosts as well as the management of cloud resources such as virtual machines and networks. Of course, Puppet can also play an important role in the management of the actual workload of virtual machine instances. Besides using it in the traditional, purely agent-based way, it is also possible to use Puppet during the building of machine images. This serves two purposes: firstly, it speeds up the initial Puppet run when an instance is launched off that image, sometimes quite dramatically. Secondly, it supports operating immutable infrastructure without losing Puppet’s benefits to organize and simplify the description of the entire infrastructure.

David is a principal engineer at Puppet Labs and the technical lead for Puppet Labs’ development of Razor. Before joining Puppet Labs, David worked at Red Hat on a variety of management tools and served as the maintainer of Apache Deltacloud. He was one of the earliest contributors to Puppet, and is the main author of the Augeas configuration management tool.

vOneCloud: The Simplest Alternative to vCloud

We are glad to announce the Beta release of vOneCloud, a CentOS Linux virtual appliance for vSphere that contains all required OpenNebula services optimized to work on existing VMware vCenter deployments. 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. vOneCloud deploys an enterprise-ready OpenNebula cloud just in a few minutes where the infrastructure is managed by already familiar VMware tools, such as vSphere and vCenter Operations Manager, and the provisioning, elasticity and multi-tenancy cloud features are offered by OpenNebula.

vOneCloud is our answer to those companies 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 cannot 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



vOneCloud is for companies that want to keep VMware management tools, procedures and workflows. vOneCloud seamlessly integrates running vCenter virtualized infrastructures so leveraging the advanced features such as vMotion, HA or DRS scheduling provided by the VMware vSphere product family. On top of it, OpenNebula exposes a multi-tenant, cloud-like provisioning layer, including features like virtual data centers, datacenter federation or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. You also take a step toward liberating your stack from vendor lock-in.

It is all about simplicity. vOneCloud is extremely simple to install, adopt, update and use. Why do not you give a try to vOneCloud to manage your VMware environment?. We look forward to your feedback.

OpenNebula Newsletter – October 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 are excited about China Mobile’s impressive announcement of their Mobile Cloud based on OpenNebula! Read below.


Winter is coming, be prepared with the warm Fox Fur of the new stable release of OpenNebula: 4.10. Did you have a chance to try it out yet? We would love to hear your feedback, so we have time to include possible changes in the next maintenance release. You can reach us through the user mailing list, praise is also welcome! But we do not kick back and coast, and we have already started work that will eventually lead to OpenNebula 4.12.

This release ships with several improvements in different subsystems and components. But probably the most important novelty is the new integration with VMware vCenter. OpenNebula 4.10 is able to interact with a farm of ESX servers without contacting them individually, but rather through their associated vCenter. This turns Fox Fur in the first OpenNebula release that allows to automatically import an existing infrastructure, since the new vCenter drivers allow to import Clusters and Virtual Machines from a vCenter installation, significantly smoothing the set up curve.

Adding to the above, this integration will leverage vCenter advanced features such as vMotion, HA or DRS scheduling provided by the VMware vSphere product family. OpenNebula will expose on top of existing vCenter clusters a multi-tenant, cloud-like provisioning layer, offering virtual data centers, datacenter federation or hybrid cloud computing to connect in-house vCenter infrastructures with public clouds. In this manner, adopters will take a definitive step toward liberating their stack from vendor lock-in.

Fox Fur also introduces an integrated tab in Sunstone to access OpenNebula Systems professional support, avoiding disruption of work and enhancing productivity. Moreover, several improvements are scattered across every other OpenNebula component: improvements in the hybrid drivers, including better Sunstone support, improved auth mechanisms (login token functionality) and many bugfixes stabilizing features introduced in Lemon Slice.


Recently, China Mobile announced in our blog their cloud based on OpenNebula. We are very excited to see a project of the scale and importance of using OpenNebula as the base of their infrastructure, leveraging the matureness of your favourite CMP with a well proven infrastructure set up:

the platform has been running for two years and proven to be stable enough to manage more than 600 physical servers and thousands of VMs

Our community has been very active this last month. For instance, do you like Ansible and OpenNebula? Look no further! Read here how this two proven technologies play with each other, thanks to Vincent Vanderkussen. Are you instead living on a Windows world, and like .NET? Play with OpenNebula as well thanks to our partners at Terradue.

OpenNebula keeps growing in Croatia, with a new web hosting company presenting their Win VPSs based on ONE. Also, It’s always refreshing to see how OpenNebula is helping people, thanks Daniel for sharing! Spanish speakers can dwell into this study, placing OpenNebula as the only european open source technology to build clouds.

Comparing with others is always a healthy exercise, check out Carlo view on OpenNebula and OpenStack.


This year’s OpenNebula Conference, to be held in Berlin 2-4 of December, 2014 is round the corner. Check the final agenda at the conference page, with folks from PuppetLabs, E-Post, Deloitte and many other companies sharing their experiences with production clouds based on OpenNebula. Moreover, check out the venue for the evening event, and register soon if you like it since there are few places available.

Last but not least, if you are interested in reaching a wide cloud audience, check the sponsorship opportunities for the OpenNebula Conference 2014.

If you live in Spain, and around Extremadura, do not miss out the OpenNebula course next 11th and 12th of this month.

OpenNebula team members were on the road this last month to spread the OpenNebula word. For instance, in Santiago de Compostela, Spain, a TechDay was held with Agasol, with great audience response. We learned for instance how the Supercomputing Center of Galicia (CESGA) is using a hybrid OpenNebula cloud.

OpenNebula was present in Europe ICT Proposer’s Day. We were also present in the spanish Digital Agenda Day, where both the OpenNebula project and OpenNebula Systems expressed their inconditional love for open source technologies.

In our mission of spreading we went to Düsseldorf for the LinuxCon Cloud Open. And held another Tech Day in Barcelona, where a great and numerous audience learned about OpenNebula.


We have more upcoming TechDays in future months, if you are interested in OpenNebula you can check the project page.

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.

OpenNebula 4.10 Fox Fur is Out!

The OpenNebula team is pleased to announce the immediate availability of the final version of OpenNebula 4.10, codename Fox Fur. This release ships with several improvements in different subsystems and components. But, more importantly, it features a little revolution in shape of vCenter support.

This is the first OpenNebula release that allows to automatically import an existing infrastructure, since the new vCenter drivers allow to import Clusters and Virtual Machines from a vCenter installation, significantly smoothing the set up curve. The concept of the vCenter drivers is akin to the hybrid cloud approach in the sense that OpenNebula will delegate a number of aspects to vCenter, instead of pursuing the management of almost every aspect as it traditionally does with the three supported hypervisors. OpenNebula will use pre defined Virtual Machine Templates existing in the vCenter set up to launch Virtual Machines, very much like it does in its hybrid drivers to access Amazon EC2, IBM SoftLayer and Microsoft Azure, although offering extra features like for instance VNC support and more lifecycle actions.

A refinement has been performed in the OpenNebula networking system, extended in the previous release in order to allow a flexible management of IP leases, decoupling the host-hypervisor configuration attributes with the IP/L3 configuration attributes. In this refinement, end users are allowed to update their VNET reservations and also the address range of their reservations, so they can introduce attributes to be passed along their VMs through contextualization, customizing their VMs network settings in this manner.

Another nifty feature is related to the fact that we are aware that access to professional support in production environments support is a must. Fox Fur introduces an integrated tab in Sunstone to access OpenNebula Systems (the company behind OpenNebula, formerly C12G) professional support. In this way, support tickets management can be performed through Sunstone, avoiding disruption of work and enhancing productivity.

Several improvements are scattered across every other OpenNebula component: improvements in the hybrid drivers, including better Sunstone support, improved auth mechanisms (login token functionality), a solution for the spurious Poweroff state, and many other bugfixes that stabilized features introduced in Lemon Slice.

As usual OpenNebula releases are named after a Nebula. The Fox Fur Nebula (IC 3568) is located in Monoceros and included in the NGC 2264 Region.

This is a stable release and so a recommended update. It incorporate important improvement since 4.8 and several bug fixes since 4.10 Beta. Be sure to check the compatibility and upgrade guides. We invite you to download it and to check the QuickStart guides, as well as to browse the documentation, which has also been properly updated.

Network extension model refinement and login token functionality in OpenNebula 4.10 were funded by BlackBerry in the context of the Fund a Feature Program.

Thanks the community members and users who have contributed to this software release by being active with the discussions, answering user questions, or providing patches for bugfixes, features and documentation.
