OpenNebula 4.0 Eagle is Out!

The OpenNebula project is proud to announce the immediate availability of OpenNebula 4.0 Eagle. The project has come a long way since the first “technology preview” of OpenNebula five years ago. During these years we’ve witnessed the rise and hype of the Cloud, the birth and decline of several virtualization technologies, but specially the encouraging and exciting growth of OpenNebula; both as a technology and as an active and engaged community.

OpenNebula 4.0 is the result of the terrific feedback of the day-to-day operation of virtualized infrastructures by many of you, result of all your contributions, bug reports, patches, and translations, but one and foremost, OpenNebula 4.0 is the realization of a vision of simplicity, openness, code-correctness and a sysadmin-centric approach. This defines our personality as a community, it defines the OpenNebula Way. Now the features that you’ve been waiting for….

OpenNebula 4.0 includes new features in most of its subsystems. We are showing for the first time a completely redesigned Sunstone, with a fresh and modern look and an updated workflow for most of the dialogs. The also new Sunstone Views functionality allows to customize the GUI for each type of user or group, so the interface implements a different provisioning model for each role. A whole new set of operations for VMs like system and disk snapshoting, capacity re-sizing, programmable VM actions and IPv6 among others. There are some new drivers also, like Ceph; as well as improvements for VMware, KVM and Xen. The scheduler has received some attention from the OpenNebula team to easily define more placement policies… and much more (see below).

This is a stable release and so a recommended update that incorporates several bug fixes since 4.0 Beta and 4.0 RC. Although this is a major release we’ve done our best to keep compatibility with OpenNebula 3.8 so any application developed for previous versions should work without effort. We have changed the name of some of the operations over the VM (we have now 32 different management actions) so be sure to check the compatibility and upgrade guides.

As enterprise-ready product, each OpenNebula Series is maintained for three years, in few days we will release the first Service Pack for the OpenNebula 3 Series.

As usual OpenNebula releases are named after a Nebula. The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745-46. It is located about 7,000 light-years away from Earth.

Thanks to all people that have contributed to OpenNebula 4.0!
