New oVirt Project Underway

As oVirt continues to grow, the many projects within the broader oVirt community are thriving as well. Today, the oVirt community is pleased to announce the addition of a new incubator subproject, Vagrant Provider, as well as the graduation of another subproject, moVirt, from incubator to full project status!

According to maintainer Marc Young, Vagrant Provider is a provider plugin for the Vagrant suite that enables command-line ease of virtual machine provisioning and lifecycle management.

Testing ovirt-engine changes without a real cluster

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.

oVirt Software Defined Networking, The OVN Network Provider

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.

Call For Proposals—FOSDEM 2017 Virtualization & IaaS DevRoom

FOSDEM logo 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.

Manage oVirt with Ansible Playbooks

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 virtual infrastructure. It only makes sense, then, to integrate with Ansible, another powerful IT automation tool. We are happy to announce the creation of new Ansbile modules that will enable the management of an oVirt environment via playbooks.

Up and Running with oVirt 4.0 and Gluster Storage

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 that's grown to take on a bunch of complementary tasks. For this process, it'll save us a bunch of typing and speed things up significantly.

Important Note: I want to stress that while Red Hat has recently begun to sell and support a converged virtualization and storage configuration on a limited basis, the converged oVirt/Gluster setup I describe here should be considered somewhat bleeding edge.

If you're looking instead for a simpler, single-machine option for trying out oVirt, your best bet is the oVirt Live ISO. This is a LiveCD image that you can burn onto a blank CD or copy onto a USB stick to boot from and run oVirt. This is probably the fastest way to get up and running, but once you're up, this is definitely a low-performance option, and not suitable for extended use or expansion.

Monitoring Improvements in oVirt

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.
