In mid-March, our Engineering Team (whose members, along with the rest of the OpenNebula Team, have been working from home for three weeks already) announced Hotfix Release 5.10.3. While OpenNebula is fully open source, packages from hotfix incremental versions are not publicly released, and are only available for users with an active support subscription. This version fixes several issues and includes a number of new features that have been backported.

One of the novelties that the forthcoming OpenNebula v.5.12 will bring along, after several months of intense work, is a fully redesigned OneFlow. This powerful component, whose new version comes with an incredible improvement in performance, allows OpenNebula users to run complex services in their private cloud, now quicker than ever!

In the meantime, if what you want is to set up a simple OpenNebula edge cloud environment for evaluation purposes, you can always refer to this new step-by-step technical guide on MiniONE recently published by bare-metal provider Packet (now part of Equinix). This one follows a first technical guide published last month.


Kudos to Mara Sorella, Postdoctoral Researcher at the Research Center of Cyber Intelligence and Information Security (Sapienza University of Rome), for inaugurating the new Cybersecurity section of our blog with a guest post on “Building Emulation Environments for Cybersecurity Analyses“, which is based on the paper she presented a few months ago in Barcelona at the OpenNebulaConf 2019. Amazing stuff!

Many thanks also to Hitesh Jethva, Technical Writer at Alibaba Cloud, for publishing in early March this great tutorial on how to install and configure OpenNebula on an Alibaba Cloud Elastic Compute Service (ECS) Ubuntu 18.04 server.


One of the many public events that have been cancelled in recent weeks due to COVID-19 is the Red Hat Summit 2020, which we were going to attend as sponsors. The event will run now on April 28-29 as a Virtual Experience. Not quite the same, but still better than nothing…

And in line with the #StayHome movement, in the coming days we’ll be publishing the details of our new Webinar series, to make sure no-one misses any of the action in a year that is becoming a turning point for the OpenNebula project. Stay tuned! πŸš€

PS: Take care of yourselves and of those around you. All our support to those who are fighting the pandemic on the front lines! πŸ’ͺ
