The OpenNebula project is proud to announce the availability of OpenNebula 3.6 (Lagoon). This release is focused on stabilizing the features introduced in OpenNebula 3.4, improving the performance of some existing features, and adding new features for virtualization management and integration with the new OpenNebula Marketplace.

OpenNebula 3.6 features a new hotplug mechanism for disk volumes that supports attaching either volatile volumes or existing images to a running VM. Also for OpenNebula 3.6 we have re-written from scratch the Quota and Accounting tools, so now they are included in the OpenNebula core to enhance their integration with the existing AuthZ & AuthN mechanisms and other related tools (e.g. Sunstone). There are some other new features like VM rescheduling, hard reboots, cloning of disk images, support for per-cluster definition of system datastores…

OpenNebula 3.6 also features improvements in other systems, especially in Sunstone’s interface with the redesign of several tabs as well as in the OpenNebula Zones where we got rid of the datamapper dependency to ease the packaging of OpenNebula.

Last but not least, OpenNebula 3.6 is fully integrated with the new OpenNebula Marketplace. Any user of an OpenNebula cloud can very easily find and deploy virtual appliances through familiar tools like the SunStone GUI or the OpenNebula CLI. The OpenNebula Marketplace is also of the interest of any software developer to quickly distribute a new appliance, making it available to all OpenNebula deployments worldwide.

This is a final release and it is aimed at production environments, any infrastructure running a previous version is recommended to upgrade.

As usual OpenNebula releases are named after a Nebula. The Lagoon Nebula (also known as M8, or NGC 6523) is a giant interstellar cloud in the constellation Sagittarius.
