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.]
The following items are required to install an OpenShift Container Platform cluster on a RHV environment.
You reviewed details about the OpenShift Container Platform installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
