Nov 22h, 2013. After the release and evaluation of the second beta of OpenNebula 4.4 (4.3.85) Retina, the OpenNebula project announces the immediate availability of the release candidate of OpenNebula 4.4 Retina.
Several improvements have been made to the cloud bursting model, including better scheduler support, better storage management (ie, prolog and epilog bypassing when cloud bursting) and improved AWS EC2 functionality support (broader monitoring, drop CLI for Ruby SDK, etc).
We are now set to basically bug-fixing and feature-freeze. Note that this is a beta release aimed at testers and developers to try the new features, and send a more than welcomed feedback for the final release.
As usual OpenNebula releases are named after a Nebula. The Retina Nebula (IC 4406) is a planetary nebula near the western border of the constellation Lupus, the Wolf. It has dust clouds and has the shape of a torus.
