oVirt’s development is continuing on pace, as the calendar year draws to a close and we get ready for a new year of development, evangelism, and making virtual machine management a simple process for everyone.
Here’s what happened in November of 2016.
Software Releases
oVirt 4.0.6 Third Release Candidate is now available
oVirt 4.1.0 First Beta Release is now available for testing

The ovirt-engine component of oVirt is the brain of oVirt and is responsible for managing attached systems; providing the webadmin UI and REST interfaces; and other core tasks. The process of setting up a real cluster on which to deploy the project is a time-consuming task that greatly increases patch turnaround time and can provide a significant barrier of entry to those wanting to contribute to the project.
Development Environment
There are couple of preparation steps you must take to create your development environment. I am using CentOS 7 as my development machine so I will use […]
oVirt offers not only its own internal networking, but also an API for external network providers. This API enables using external network management software inside environments managed by oVirt and takes advantage of their extended capabilities.
One of such solutions is OVN: Open Virtual Network. OVN is an OVS (Open vSwitch) extension that brings Software Defined Networking to OVS.
OVN enables support for virtual networks abstraction by adding native OVS support for virtual L2 and L3 overlays.
This allows the user to create as many VM networks as required, without troubling the adminstrator with vlan requests or infrastructure changes.

The oVirt community is made up of a diverse mix of individuals using and contributing to all aspects of the project from all over the world, and we want to make sure that the community is a safe and friendly place for everyone.
This code of conduct applies equally to founders, mentors, and those seeking help and guidance. It applies to all spaces managed by the oVirt project, including IRC, mailing lists, GitHub, Gerrit, oVirt events, and any other forums created by the project team which the community uses for communication.
While we have contribution guidelines for […]
I am excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2017, to be hosted on February 4, 2017.
This year will mark FOSDEM’s 17th anniversary as one of the longest-running free and open source software developer events, attracting thousands of developers and users from all over the world. FOSDEM will be held once again in Brussels, Belgium, on February 4 & 5, 2017.
This devroom is a collaborative effort, and is organized by dedicated folks from projects such as OpenStack, Xen Project, Mesos, oVirt, […]
Recently the oVirt community was pretty excited to find a series of new videos walking users through some key steps in installing and using oVirt.
The video were created by Nathan Llaneza from Coastal IT Solutions, who also teaches at a local community college.
“We needed to be able to give our students virtual machines that could be utilized from anywhere,” Llaneza explained. “We have finally been granted our second server, so now we are going to be able to let more instructors use the oVirt environment. I am building these videos to encourage more of our […]
As powerful a tool that oVirt is in the datacenter, we know it’s not the only tool that’s available for IT administrators to manage their virtual machines. A VM datacenter solution may be the best and only answer for your organization’s needs, but you may also need bare-metal and even hybrid or public cloud management.
For that reason, the oVirt project team has made concerted efforts to integrate with other management tools so you can scale your admin toolchain as needed. oVirt has already achieved such integration with ManageIQ, the open source platform that enables control of all your […]
In June, the oVirt Project shipped version 4.0 of its open source virtualization management system. With a new release comes an update to this howto for running oVirt together with Gluster storage using a trio of servers to provide for the system’s virtualization and storage needs, in a configuration that allows you to take one of the three hosts down at a time without disrupting your running VMs.
One of the biggest new elements in this version of the howto is the introduction of gdeploy, an Ansible based deployment tool that was initially written to install GlusterFS clusters, but […]
Recently I’ve been working on improving the scalability of monitoring in oVirt. That is, how to make oVirt-engine, the central management unit in the oVirt management system, able to process and report changes in a growing number of virtual machines that are running in a data center. In this post, I will elaborate on what we did and share some measurements.
Monitoring in oVirt
In short, oVirt is an open-source management platform for virtual data centers. It allows centralized management of a distributed system of virtual machines, compute, storage, and networking resources.
In this post, the […]
Hosted engine has seen a lot of progress and evolution, and today it is is the de facto recommended way to to deploy your oVirt Engine. But since that special Hosted Engine High Availability (HA) cluster itself needs management, we worked on making that be managed by the hosted engine itself, too.
Recent oVirt versions made it lot more easier to deploy hosted-engine, first by introducing the appliance and cloud-init customization
phase, next with VM configuration being stored on the shared storage and making the VM itself manageable from the UI itself. A few more under-the-hood changes resulted in storing […]
