Installing oVirt 4.2 on CentOS 7.5

Welcome to our oVirt 4.2 series (find more articles here)!  In this article, we'll go over the quick and easy install of oVirt 4.2 on CentOS 7.5.  In total, installation should take about five minutes or less.

  1. First, let's add the official oVirt 4.2 yum repo:

    yum install -y https://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm
  2. Next, we'll install oVirt Engine. Think of this as what vCenter is in the ESXi universe.

    yum install -y ovirt-engine
  3. After the installation has completed, we'll go through the initial setup:

    engine-setup
