The OpenNebula team is pleased to announce the immediate availability of the final version of OpenNebula 4.10, codename Fox Fur. This release ships with several improvements in different subsystems and components. But, more importantly, it features a little revolution in shape of vCenter support.

This is the first OpenNebula release that allows to automatically import an existing infrastructure, since the new vCenter drivers allow to import Clusters and Virtual Machines from a vCenter installation, significantly smoothing the set up curve. The concept of the vCenter drivers is akin to the hybrid cloud approach in the sense that OpenNebula will delegate a number of aspects to vCenter, instead of pursuing the management of almost every aspect as it traditionally does with the three supported hypervisors. OpenNebula will use pre defined Virtual Machine Templates existing in the vCenter set up to launch Virtual Machines, very much like it does in its hybrid drivers to access Amazon EC2, IBM SoftLayer and Microsoft Azure, although offering extra features like for instance VNC support and more lifecycle actions.

A refinement has been performed in the OpenNebula networking system, extended in the previous release in order to allow a flexible management of IP leases, decoupling the host-hypervisor configuration attributes with the IP/L3 configuration attributes. In this refinement, end users are allowed to update their VNET reservations and also the address range of their reservations, so they can introduce attributes to be passed along their VMs through contextualization, customizing their VMs network settings in this manner.

Another nifty feature is related to the fact that we are aware that access to professional support in production environments support is a must. Fox Fur introduces an integrated tab in Sunstone to access OpenNebula Systems (the company behind OpenNebula, formerly C12G) professional support. In this way, support tickets management can be performed through Sunstone, avoiding disruption of work and enhancing productivity.

Several improvements are scattered across every other OpenNebula component: improvements in the hybrid drivers, including better Sunstone support, improved auth mechanisms (login token functionality), a solution for the spurious Poweroff state, and many other bugfixes that stabilized features introduced in Lemon Slice.

As usual OpenNebula releases are named after a Nebula. The Fox Fur Nebula (IC 3568) is located in Monoceros and included in the NGC 2264 Region.

This is a stable release and so a recommended update. It incorporate important improvement since 4.8 and several bug fixes since 4.10 Beta. 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.

Network extension model refinement and login token functionality in OpenNebula 4.10 were funded by BlackBerry in the context of the Fund a Feature Program.
