Here’s our monthly newsletter with the main news from the last month, including what you can expect in the coming months.


OpenNebula 3.8 Twin Jet has just been released, check out the release notes for release highlights and a summary of the new features incorporated in OpenNebula 3.8.

OpenNebula 3.8 enhances the integration with VMware and KVM, which are the most widely used hypervisors in OpenNebula clouds, and with heterogeneous infrastructures using multiple hypervisors. Twin Jet features an improved storage VMware interface with native support for VMFS and integration with cgroups and SPICE on KVM deployments. This new version seamlessly integrates with the new Virtual Router in the OpenNebula marketplace to provide L3 services based on the OpenNebula virtual networks.

Twin Jet also enhances the EC2 Query API server, which now provides a complete implementation of the Elastic Block Store (EBS) and keypairs, along with other minor enhancements to be more compliant with the Amazon EC2 specification. The OCCI cloud API now brings new actions and hotplugging functionality.

An effort was also carried out to come closer to the popular linux distributions, the new packages for  3.8 distributed by the OpenNebula team for each supported distribution will be the same as the packages contained in the linux distros.

One of the changes introduced in OpenNebula 3.8 is the new contextualization packages The new version comes with some changes that we hope will make people creating images happier.

There is also worth emphasizing the aspects that makes OpenNebula the platform of choice for the enterprise cloud. In a nutshell: it is a production ready software, easily integrated with third party tools and with unique features the management of enterprise clouds.


An interesting study was published by C12G Labs, resulting from a survey among 820 users with a running OpenNebula cloud. The results state that  43% of the deployments are in industry and 17% in research centers, KVM at 42% and VMware at 27% are the dominant hypervisors, and Ubuntu at 31% and CentOS at 26% are the most widely used linux distributions for OpenNebula clouds.

As member of the OpenNebula community, China Mobile has posted their work on how does it take to deploy 100 virtual machines using a single instance of OpenNebula, and the answer is less than 5 minutes! The post is very interesting since it shows the configuration that China Mobile has set in their OpenNebula cloud to achieve this very nice results.

Another awesome contribution to the OpenNebula ecosystem was described by Research in Motion, giving a detailed description of the features and architecture of Carina. The Carina project was motivated by the need to speed up the deployment of services onto the OpenNebula private cloud at RIM,  it is a successful attempt to standardize the process for automating multi-VM deployments and setting auto-scaling and availability management policies in the cloud.

We want to give a big two thumbs up to our community for their amazing contributions to OpenNebula 3.8. We can highlight contributions by China Mobile, Research in Motion, Atos, FermiLab, CentOS and many others. OpenNebula’s Development Portal provides more details about the specific contributions. We would also like to thank all the people that have contributed translations for Self-Service and Sunstone, as well as to Bill Campbell, the author of the nifty integration of OpenNebula and Ceph, with a set of TM/DS/VMM scripts. Moreover, kudos to SZTAKI LPDS for the enhancement in the iSCSI drivers, focused to achieve higher reliability and stability while working with iscsi datastores with TGT server.
