Install oVirt on CentOS 7

Posted on by

Recently, as you could see in previous posts, oVirt got to my attention. oVirt is the upstream project of Red Hat Enterprise Visualization or RHEV. While oVirt it isn’t providing everything that competitor VMWare ESXi does, it comes close and is a very good alternative for smaller or home setups. For a long time, oVirt wasn’t supported on Enterprise Linux 7 (like RHEL 7 or CentOS 7) but since a short time it is. Here you can find how to install oVirt and get started.

Move a guest from VMWare ESX to oVirt or RHEV

When working in an environment where you have both a VMWare hypervisor and an oVirt or RHEV hypservisor or you want to migrate away from VMWare ESX to oVirt or RHEV, you will need a way to move or copy your current virtual machines from one to another. Unfortunately this can’t be done without downtime but at least it can be done. In this post I’ll try to explain how to successfully move a VM running on ESX or vCenter to an oVirt or Red Hat Enterprise Virtualization host.

Create a new virtual machine in oVirt with Python using the API

Recently, I started to work or play, it’s a matter of definition, a little more with oVirt. oVirt is less known than VMWare but it’s the upstream project for Red Hat’s Enterprise Virtualization (RHEV) and based on libvirt. In an earlier post, I explained how to create VM’s on VMWare vSphere environments using Python and the VMWare API. In this post, I’ll explain how to acomplish the same using the oVirt API. It turned out to be easier than I expected.

Monitor oVirt or libvirt with SNMP and Zabbix

Somehow, I expected to have little to no work when I wanted to monitor an oVirt host over SNMP. One would expect this since oVirt is the upstream project for Red Hat’s Enterprise Virtualization (RHEV) which seems to be quite strong in the market. While it isn’t that hard to get information about using SNMP for oVirt or libvirt the outcome can be disappointing. There is some documentation about it but here you can find a more hands-on explanation.
