In OpenShift Container Platform version 4.9, you can install a customized OpenShift Container Platform cluster on Red Hat Virtualization (RHV) and other infrastructure that you provide. The OpenShift Container Platform documentation uses the term user-provisioned infrastructure to refer to this infrastructure type.

The following diagram shows an example of a potential OpenShift Container Platform cluster running on a RHV cluster.

The RHV hosts run virtual machines that contain both control plane and compute pods. One of the hosts also runs a Manager virtual machine and a bootstrap virtual machine that contains a temporary control plane pod.]

Prerequisites

The following items are required to install an OpenShift Container Platform cluster on a RHV environment.

Internet access for OpenShift Container Platform

In OpenShift Container Platform 4.9, you require access to the internet to install your cluster.

You must have internet access to:

  • Access OpenShift Cluster Manager to download the installation program and perform subscription management. If the cluster has internet access and you do not disable Telemetry, that service automatically entitles your cluster.

  • Access Quay.io to obtain the packages that are required to install your cluster.

  • Obtain the packages that are required to perform cluster updates.

If your cluster cannot have direct internet access, you can perform a restricted network installation on some types of infrastructure that you provision. During that process, you download the required content and use it to populate a mirror registry with the installation packages. With some installation types, the environment that you install your cluster in will not require internet access. Before you update the cluster
