The Supercomputing Center of Galicia (CESGA) and the Supercomputing Center Foundation of Castilla y León (FCSCL) have built a federation of cloud infrastructures using the hybrid cloud computing functionality provided by OpenNebula. Both organizations have collaborated in order to execute an application to fight Malaria across both sites. This is a very interesting use case of cloud federation in the High Performance Computing field.
Last week at ISC Cloud 2010, Ulrich Schwickerath, from the CERN IT-PES/PS Group, presented the last benchmarking results of CERN’s OpenNebula cloud for batch processing. The batch computing farm makes a critical part of the CERN data centre. By making use of the new IaaS cloud, both the virtual machine provisioning system and the batch application itself have been tested extensively at large scale. The results show OpenNebula managing 16,000 virtual machines to support a virtualized computing cluster that executes 400,000 jobs.
As you know, OpenNebula 2.0 is out the door, and we’re delighted with the response from our community. Besides the huge spike in downloads, we have received many congratulations over email and Twitter from many of our users, specially those who are deploying OpenNebula in very large infrastructures. However, we would like to take a moment to acknowledge that, if OpenNebula 2.0 has gotten so far, it is in no small measure due to the many users and organizations in our community who have actively contributed to OpenNebula.

At OGF30, after OpenNebula’s keynote, Dr. Daniel A. Reed, Corporate Vice President Extreme Computing Group & Technology Strategy and Policy at Microsoft, gave an excellent keynote speech about cloud and the future of research. Dr. Reed also presented the new EU-funded VENUS-C project, coordinated by Engineering and aimed at developing, testing and deploying an industry-quality Cloud Computing service for Europe. Microsoft announced that it will work with VENUS-C partners to implement a bridge between Windows Azure and OpenNebula.
We are very happy to announce this collaboration that will extend the current level of interoperability and portability provided by OpenNebula.
The OpenNebula team is very proud to announce the release of a new stable version of the OpenNebula Toolkit! That’s right, OpenNebula 2.0 is now available for download.
OpenNebula 2.0 marks the end of a large and laborious release cycle and an important milestone for the project in terms of functionality, maturity and community engagement. Apart from improved scalability and robustness and many exciting new features, we have also opened the project QA & testing procedures and created a new add-on section for high-quality, third-party open-source components.
OpenNebula 2.0 includes a significant amount of changes and new features across many areas. The following is a selection of notable new functionality:
Image Repository. The Image Repository allows users to easily specify disk images from a catalog without worrying about low-level disk configuration attributes or block device mapping. Also, image access control is applied to the images registered in the repository, hence simplifying multi-user environments and image sharing. The traditional method of specifying VM disks is also fully supported. More info…
MySQL support. OpenNebula can now work with either a MySQL or SQLite database backend. The new MySQL support brings important performance and scalability improvements compared to the SQLite implementation. MySQL is the recommended option for large-scale clouds. More info…
Improved VMWare support. VMware drivers has been re-written to make use of all the features offered by OpenNebula, making the functionality of the drivers on par with the KVM and Xen ones. The new drivers uses the libvirt driver. More info…
Scalability Improvements. Several components of OpenNebula have been tuned to work with tens of thousands of VMs, including the redesign of the scheduler and adjustments to the monitoring modules.
Separate VM and Information actions. The specific operations performed when monitoring a host or performing an specific operation on a VM has been decoupled from the driver code base. Now it is even easier to tune your cloud. The number of connections to the node have also been reduced.
Cluster support. Physical hosts can now be grouped in logical clusters, so after a cluster is defined it can be used to set the placement of a VM. More info…
Accounting. New tools are provided to generate accounting reports for cloud users or physical hosts. More info…
Authorization & Authentication Drivers. The authorization and authentication processes in OpenNebula have been totally redesigned. Now they can be handled natively by the OpenNebula core, offering the same functionality as OpenNebula 1.4. Alternatively, the A&A processes can be handled by an external component that can be integrated with any A&A system or user maps (e.g. LDAP, Kerberos…). As an example OpenNebula 2.0 features a quota based authorization module and user authentication based on RSA keys. More info…
Quota Management. Allowing cloud administrators to set limits on cloud resources for users
LDAP Integration. Levering the new authorization & authentication framework, datacenters using LDAP for user management can integrate OpenNebula with it, without the need of re-creating the user data. More info…
Virtual Networking Improvements. OpenNebula 2.0 lets you define generic attributes associated to a Virtual Network (e.g. gateway, dns servers…) that can then be included in the context of a VM. This will let you easily configure VMs with multiple NICs. Additionally Virtual Networks can now be defined as public, and thus shared among multiple users.
Improved EC2 support. The EC2 Query server can now be used with the EC2 ecosystem. Supported third party applications include ElasticFox or EucaTools. More info…
Java Bindings for the OpenNebula Cloud API (OCA) OpenNebula 2.0 includes JAVA bindings that wraps the XML–RPC interface methods exposed by the core. More info…
Improved OCCI support. The OCCI implementation now follows a more coherent schema. The OCCI server also makes a more robust handling of incoming requests. More info…
For a complete list of changes, see this detailed changelog
For a detailed list of bugs addressed by OpenNebula 2.0 check the development portal.
OpenNebula 2.0 is targeted at production environments and 1.4 installations are recommended to update. However, take into account that, starting with OpenNebula 2.0 Beta, a new DB schema was introduced. Thus, this new release will break compatibility with OpenNebula 1.4 (at the DB and API levels). Host, Networks or Virtual Machines defined in OpenNebula 1.4 installs will not longer work with this release, and must be recreated in the new system (we are working to make this process more seamless in future releases). OpenNebula 2.0 also includes new API calls and methods. However there have been no changes in those API calls already supported in OpenNebula 1.4. Applications using OCA (Ruby and Java bindings) are expected to work with OpenNebula 2.0.
Finally, we would like to thank all the people and organizations that have contributed to make OpenNebula the most flexible, scalable and feature rich Cloud Toolkit!
The OpenNebula Team
OpenNebula 2.0 is right around the corner, and we were curious to see how much effort has gone into it. As it turns out, nearly double the effort we put into version 1.4, at least measured by the number of lines inserted/deleted/modified in our code repository:
Of course, lines of code are a notoriously imprecise metric, so take the above with a healthy dose of salt. Plus, the above doesn’t account for the additional effort we’ve put into quality assurance, preparing documentation, helping users on IRC and on the mailing list, etc.
In any case, we’re really happy with the 2.0 release cycle, and specially with all the great contributions and feedback we’ve gotten from our community. Looking at the above graph, we’re also amazed at how far OpenNebula has come, from a small technology preview that we initially just ran on a small cluster to a stable and well-tested piece of software capable of wrangling tens of thousands of virtual machines. Another interesting fact about the OpenNebula source code is the number of programming languages and technologies used: C++/C (63.02%), Ruby (21.89%), Java (6.19%), Shell Script (5.79%), Lex & Yacc (2.13%).
So stay tuned… before you know it, you’ll be getting a release announcement from us!
Last months have been quite busy for the team, a bunch of new features has been added to OpenNebula core as well exciting new components. There has been however a huge amount of effort that may go unnoticed in the upcoming OpenNebula 2.0 release. As part of this release we also wanted to open our internal QA & testing procedures to the community… so OpenNebula QA was born!
Testing & QA of a cloud management tool is particularly challenging as it requires to verify the integration of multiple software components, from different hypervisors (Xen, VMware & KVM) and storage architectures (SSH, NFS) to operating systems (Ubuntu and CentOS) and DB backends (MySQL and sqlite). Just check the OpenNebula QA page for a description of the automated test suite we are using, or if you want to check how your favorite Cloud toolkit behaves go to hudson.opennebula.org!
