Technology

Good news for our beloved users, OpenNebula 5.4.6 is here! This release brings a lot of bug fixes and some new functionalities.

Recent news regarding to Meltdown and Spectre vulnerabilities put OpenNebula team to work hard trying to alleviate performance issues. Well, do not worry, fortunately we came up with a solution. Now you will be able to specify your host’s CPU model so that KVM virtual machines can improve their performance and security. How does this work? You can find more technical details on this link

Some bugs have been also fixed on this release:

• The network topology now works as a charm with networks with over a thousand machines.
  You can see how we managed to do so here.
• As some of you requested, we have also include new commands to onedb on the CLI. These new commands will be extremely useful for recovery purposes, like for example, adjusting the showback.
  • update-history
  • show-history

Of course these are just some examples, for the full list of features and fixes you can always visit our documentation.

The team has rev the engines for the next major release, OpenNebula 5.6. Stay tuned for exciting new features!

OpenNebula team wants to welcome OneHost Cloud. They announced recently via Twitter, OneHost is migrating from OpenStack to OpenNebula.

We have chosen Opennebula to build our new cloud platform which will provide increased performance and simplicity for our current and future customers.

We recommend reading this article where the reasons for this change are listed and explained. It was amazing to find out that before making this turn, OneHost Cloud consulted experts on cloud:

after consulting many experts in the cloud arena we have felt comfortable implementing such platform to replace our current VMware and Openstack cloud

An enlightening tutorial was made by our colleagues from Pandora FMS. In this tutorial you will learn how to do the monitoring of your cloud using OpenNebula, along with other useful tips.

Cheering news coming from Virtuozzo. They have added support for OpenNebula. Now users will be able to manage their Virtuozzo Hyperconverged Infrastructure through OpenNebula. All the benefits of this synergy are described in this excellent post, written by, Stanislav Khalup, program manager at Virtuozzo.

As announced in our forum, one of our most experienced users, Rafael del Valle, has created PyOne, which is a fantastic implementation of OpenNebula’s XLM-RPC bindings in Python. If you are interested in seeing how this works check this link.

Also this month, Valentina Zaccolo from the National Institute of Nuclear Physics in collaboration with INDIGO DataCloud, has published a very interesting post related to the implementation of a Fair Share Scheduler for OpenNebula. We already heard about it in our last OpenNebulaConf, but do not worry if you couldn’t assist, this article is very explanatory and easygoing.
