[one-users] OpenNebula 4.4 Retina Beta (4.3.80) is Out!

[Tino Vazquez]

Dear Community,

This is the official announcement of OpenNebula 4.4 Retina Beta
(4.3.80). This release includes important features that meet real
demands from production environments, with a focus on optimization of
storage, monitoring, cloud bursting, and public cloud interfaces.

OpenNebula Retina includes support for multiple system datastores,
which enables a much more efficient usage of the storage resources for
running Virtual Machines. This feature ships with different scheduling
policies for storage load balancing, intended to instruct OpenNebula
to spread the running Virtual Machines across different storage
mediums to optimize their use. This translates in the ability to
define more than one disk (or other backend) to hold running VMs in a
particular cluster. Monitorization subsystem in OpenNebula underwent a
major redesign as well, effectively switching from a pulling mechanism
to a pushing model, with the implications in scalability improvements.

An important effort has been made in the hybrid cloud model (cloud
bursting). Using the AWS API tools have been deprecated in favor of
the new Ruby SDK released, which allows the support of new AWS
mechanisms like for instance IAM. Also, now is possible to fully
support hybrid VM templates. Moreover, the AWS public cloud interface
implemented by OpenNebula has been revisited and extended to support
new functionality, as well as improved so the instance types are
offered to the end user from OpenNebula templates.

We are now working on two more features to be added post-beta: support
for CephX and native KVM support for glusterFS, the rest of the code
is in feature freeze and just bug fixes will be added. 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.

Behold the clouds with your Retina, they just look nicer ;)
