The OpenNebula team is pleased to announce the immediate availability of the final version of OpenNebula 4.6, codename Carina. This release introduces important improvements in several areas. The provisioning model has been greatly simplify by supplementing user groups with resource providers. This extended model, the Virtual Data Center, offers an integrated and comprehensive framework for resource allocation and isolation. Another important new feature has taken place in the OpenNebula core. It has undergone a minor re-design of its internal data model to allow federation of OpenNebula daemons. With OpenNebula Carina your users can access resource providers from multiple datacenters in a federated way.
With Carina the OpenNebula team has started a journey to deliver a more intuitive and simpler provisioning experience for users. Our goal is level the final user usability with the system administration and operation ones. OpenNebula Carina brings a new cloud provisioning portal with a simpler, clean and intuitive design. The Sunstone graphical interface has also been tweaked to help implement common cloud admin workflows and improved in order to support the new Marketplace version, which makes even easier for a user to get a virtual application up and running.
Finally, some other areas have received the attention of the OpenNebula developers, like for example a better Gluster support through libgfapi, improved access to large pools pagination, or optionally limit the resources exposed by a host, among many others are included in Carina.
This is a stable release and so a recommended update that incorporates several bug fixes since 4.6 RC. We’ve done our best to keep compatibility with OpenNebula 4.4, so any application developed for previous versions should work without effort. In any case, 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.
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.
