OpenNebula 3 Virtual Data Centers Screencast

A new episode of the screencast series is now available at the OpenNebula YouTube Channel.

This screencast, second part of the oZones screencast, shows how to manage and use Virtual Data Centers, both with the oZones CLI and with the oZones web-based interface, to isolate virtual infrastructure environments within an OpenNebula zone. It shows how to create a VDC by assigning a group of users to a group of physical resources and by granting one of the users, the VDC administrator, with privileges to manage all virtual resources in the VDC. The users in the VDC, including the VDC administrator, only see the virtual resources and not the underlying physical infrastructure, and can create and manage virtual compute, storage and networking capacity.

Enjoy the screencast!

OpenNebula 3.2 Red Spider is out!

January 17th, 2012. The OpenNebula project is happy to announce the availability of the stable release of OpenNebula 3.2. This release of OpenNebula features important improvements in security, networking and user management. It also fully integrates C12G addons, previously only available for OpenNebulaPro customers.

As main new features, OpenNebula 3.2 incorporates an easily-customizable self-service portal for end-users that greatly simplifies VM provisioning in the data center. This new update of OpenNebula also brings the highest levels of flexibility, stability, scalability and functionality for VMware-based data centers and clouds in the open-source domain. OpenNebula 3.2 provides an open management platform that compares to vCenter and vCloud, that can moreover be adapted to fit into your environment.

As usual OpenNebula releases are named after a Nebula. The Red Spider Nebula (NGC 6537) is a bipolar planetary nebula in the constellation Sagittarius.

Highlights of OpenNebula 3.2

Notable improvements include, but are not limited to:

  • VMware, out-of-the-box support for VMware that now includes live migration, advanced contextualization, image and network management.
  • Self-Service Portal, a new easy-to-use web-based end-user interface that complements the existing GUIs for the operation of the data-center (OpenNebula Sunstone) and for the management of multiple zones (OpenNebula Zones).
  • User & Group Management, to easily share virtual resources with other users and groups.
  • Improved Security, that fixes security issues and incorporates new authentication drivers and performance improvements.
  • Networking Drivers, a new set of drivers are now available to perform networking setup operations.
  • Data Center Placement Policies, placement policies can be defined globally to optimize the resources of the datacenter. There are 4 predefined policies: packing, striping, load-aware, and custom.

OpenNebula Self-Service Preview

OpenNebula 3.2 will be released in a few days. Along with other major features, it will include a new easy-to-use web-based end-user interface: OpenNebula Self-Service. This new GUI will complement the existing GUIs for the operation of the cloud (OpenNebula Sunstone) and for the management of multiple zones and virtual data centers (OpenNebula Zones ).

OpenNebula Self-Service is meant to offer a simplified interface to end-users of  the OpenNebula cloud. Self-Service works on top of OpenNebula’s OCCI server and it allows users to easily create, deploy and manage compute, storage (including upload of images) and network resources in seconds. Its aim is to offer a simplified access to shared infrastructure for non-IT end users.

On top of that, OpenNebula Self-Service will come ready to be re-branded, as it is easily customizable (icons, help texts and logos). Last but not least, it will include internationalization support.

Here are some screenshots of the new graphical user interface:

OpenNebula 2011: Year in Review

As 2011 draws to an end, we’d like to review what this year has meant for the OpenNebula project and give you a peek at what you can expect from us in 2012. You have all the details about the great progress that we have seen for the OpenNebula project in our monthly newsletters that we started in June.  Most of the time has been spent developing new features to continue to deliver the open-source industry standard for data center virtualization, offering the most feature-rich and flexible solution for comprehensive management of virtualized data centers.


The stable version of OpenNebula 2.2 was released in March with the new SunStone GUI and important new features for fault tolerance and scalability. Seven months later, in October, the project released OpenNebula 3.0 with management of zones and virtual data centers, new authentication methods with usage quotas, a VM template repository, a new monitoring and accounting service, and a new network subsystem with support for Open vSwitch and 802.1Q tagging. OpenNebula 3.0 features the latest innovations in cloud computing for the deployment of cutting-edge enterprise-ready on-premise IaaS clouds.

A few days ago we announced the availability of the Release Candidate of OpenNebula 3.2. This is the first version developed within the new rapid release development cycle that will allow us to more quickly deliver new features and innovations to the community as well as incorporate our users’ requirements and feedback from the community. OpenNebula 3.2 focuses on network management, security management, enhanced VMware support, and a new OpenNebula self-service portal.

C12G Labs has delivered new versions of its addons to support VMware, accounting and LDAP. These addons are being incorporated into the main distribution of OpenNebula 3.2. In 2011, C12G announced several releases of the OpenNebulaPro distribution providing the rapid innovation of open-source, with the stability and long-term production support of commercial software.


Last month, we celebrated OpenNebula’s fourth birthday. We took that opportunity to look back at how the project has grown in the last four years. OpenNebula has evolved into an active open-source project with a community that, by many measures, is more than doubling each year.  In 2011, had more than 600,000 visits and 7,000,000 page views.

During 2011, several new components have been contributed to the OpenNebula ecosystem, like SVMSchedPython bindings for OCA , VirtualBox driver, OpenVZ driverStudiCloud or OCCI 1.1 Implementation, and many organizations contributed new guides and experiences to our blog. 2011 also saw a truly remarkable growth in the number of organizations and projects using OpenNebula, and many large companies and research centers were added to our list of featured users.

We revamped the OpenNebula community wiki, which now has its own site: Many OpenNebula community members have used this wiki to share howtos or provide links to guides, white papers, or use cases. We have collaborated with the main open-source projects in the cloud computing domain, such as CFengineLibcloud, Puppet, Xen Cloud Platform, CompatibleOne, OpenVirtualization Alliance… , and companies in the virtualization market, such as Microsoft, which is providing technical guidance to help us add and maintain Hyper-V on the list of officially supported hypervisors. OpenNebula is now part of the repositories of the main Linux distributions: OpenSUSEFedoraDebian and Ubuntu.

We were excited to hear that several public organizations, like UK’s Cabinet Office, the Canadian Cloud Best Practices Council, or the European Commission, reference OpenNebula as an interoperable enterprise-ready open-source alternative to proprietary solutions for cloud computing. We created a new working group to help support the development of standards around OpenNebula.


OpenNebula presented 20 keynotes, invited talks and tutorials in the main international events in cloud computing in 10 different countries

About 2012

The final release of OpenNebula 3.2 will be available in a few days. This update of the 3 series focuses on network management, security management, and out-of-the-box enhanced support for VMware clouds. It also features a first version of the new OpenNebula Self-Service Portal for end-users of the cloud. But that’s not all! We have also started developing the new features that will be available in OpenNebula 3.4, due in Q1 2012. In fact, we’re planning four major releases of OpenNebula in 2012.

In the coming year, we hope to accelerate the initiatives to support our wide community of users and developers, and the ecosystem of open-source components and innovative projects being created around OpenNebula. In addition, we’ll be ramping up some of our plans around developing training materials, collaborating with other communities, and doing our best to help grow the OpenNebula community in a sustainable way. We will also announce new collaborations with leading IT companies in open-source and innovation in cloud computing management.

If OpenNebula has become such a successful open source project, it is in no small part thanks to its awesome community of users and developers. We have updated the list of people that have contributed to OpenNebula during the last four years. Please send us an email if we forgot to include your name. We appreciate your feedback and welcome your comments on all issues. The team will be monitoring this post for the next weeks or so and will try and answer all the questions we can.

Thanks for continuing to spread the word. We’d also like to take this opportunity to wish you health, happiness and prosperity in 2012 to you and your loved ones!

On behalf of the OpenNebula project.

OpenNebula 3.2 RC 1 (3.1.90) out!

Two days before Christmas the OpenNebula team was able to get all the green lights in the Christmas tree as well as in the Jenkins console. A good number of bug fixes has been packed with the OpenNebula 3.2 Release Candidate (RC). This release does not include any new features, but the team (the unlucky part of it) is working this Christmas to get in shape a couple of new additional components to the OpenNebula distribution…

Note that VMware drivers are not fully integrated yet in the release. Data Centers using VMware are advised not to update to this version.

Merry Christmas and cloudy new year!


OpenNebula 3 oZones Screencast

A new episode of the screencast series is now available at the OpenNebula YouTube account.

This screencast shows the ability of the oZones component to manage several instances (zones) of OpenNebula, potentially hosted within the same data center to enhance isolation, scalability and performance, or in different data centers to build a geographically distributed multi-site cloud. The oZones server offers a single access point, and centralized management and monitoring, for multiple zones, providing the ability to show their aggregated resources: templates, images, users, virtual machines, virtual networks and hosts.

Again, enjoy the screencast!

OpenNebula 3.2 Beta released!

The OpenNebula project announces the general availability of the first beta release of OpenNebula 3.2. This is the second release of the OpenNebula’s new development cycle. With this release we start the process of integrating C12G addons-contributions into OpenNebula main distribution, hence the VMware drivers are not fully functional on this beta. Clouds using VMware hypervisor are advised not to update.

With this Beta release, the master branch of the OpenNebula repository is in a feature-freeze mode and the OpenNebula developers concentrate on fixing bugs and smoothing rough edges in the software.


OpenNebula 3.2 Bringing Full Support for VMware

We are very happy to announce that the OpenNebula add-ons will be released under Apache license and incorporated into the main distribution of OpenNebula. The LDAP authentication, the accounting toolset and the VMWare support will be included in subsequent OpenNebula releases without needing to download any additional component. OpenNebula 3.2 support for VMware will also include the following new features that have been developed by C12G Labs for its customers and partners:
  • Support for VMware’s vMotion to allow live migration of VMs between VMware hosts, enabling load balancing between cloud worker nodes without downtime in the migrated VM.
  • Support for contextualization to provide a method to pass arbitrary data to a VM, enabling the configuration of the services at boot time.
  • Support for non-cloned, non-persistent disks, enabling the configuration of multiple Windows VMs using the same base non-persistent disk.
  • Support for SSH disk transfers, a replacement for the out-of-the-box shared filesystem Transfer Manager drivers, allowing the copy of the VM disks using the OpenSSH protocol, instead of relying on a shared datastore between the OpenNebula front-end and the VMware hypervisor hosts.

OpenNebula 3.2, pre-release 1!

November 18th, 2011. Today we announce the general availability of the first pre-release of OpenNebula 3.2. With this release we make our debut with a new development cycle that aims at rapidly delivering new features to the community and faster react to their needs and feedback.

The pre-release series are not suitable for production environments as you may find some rough edges. However the packages have gone through the standard testing procedure made for final releases so you should consider them stable. The first pre-release of OpenNebula 3.2 includes important new features and improvements in the security area, and in the management of networks, users and VM images.

With this release we also wanted to celebrate our 4th birthday. Happy testing everybody!


Four Years of the OpenNebula Project

Back in November 2007 (four years ago!) we published the first OpenNebula project website (see what it looked like back then, thanks to the Internet Archive), as we geared up for our first release of code (which did not take place until March 2008). The OpenNebula project was created as a way to transfer the main results of our cutting-edge research on efficient management of virtualization in large-scale distributed infrastructures and, since our first software release, OpenNebula has evolved into an active open-source project with a community that, by many measures, is more than doubling each year:

  • Website Access. From 35,842 visits and 285,965 page views in 2008 to 579,571 visits and 6,992,300 page views in 2011, which means a 150% and 190% average annual growth respectively. During the last week we had 15,300 visits, 194,000 page views, and 570,000 hits.
  • Mailing List. From 227 messages in 2008 to 4,341 in 2011, which means a 170% average annual growth. At present we have more than 800 registered users.
  • Downloads from Project Site. From 1,865 downloads in 2008 to 25,200 in 2011, which means a 140% average annual growth. In the last week, we had 900 downloads. These numbers do not include the OpenNebula packages distributed in openSUSE, Ubuntu or Debian, the downloads from our code repository, or the several cloud solutions embedding OpenNebula.
  • Codebase History. From 30,000 lines of code in 2008 to almost 300,000 in 2011. Another interesting fact about the source code is how OpenNebula effectively uses several programming languages and technologies. Nevertheless, each programming language has its relative strengths and provides unique features to meet the needs of the different components in the architecture. Ohloh provides a very nice interface to see inside OpenNebula development and to compare it with other open-source projects.

These stats highlight the success of our strategy to deliver a fully open-source, Apache-licensed cutting-edge technology with the stability, the integration capabilities, and the latest innovations in Data Center virtualization to enable the most demanding cloud environments. OpenNebula features address real needs of leading IT organizations that depend on OpenNebula for their production environments. The requirements of our users are the driving force behind all our development efforts and we recently announced a new release cycle to improve user satisfaction by rapidly delivering changes based on user requirements and feedback. In other words, giving users what they want more quickly, in smaller increments, while additionally increasing technical quality.

Congratulations everyone for this 4th birthday of OpenNebula!
