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.
You have a supported combination of versions in the Support Matrix for OpenShift Container Platform on Red Hat Virtualization (RHV).

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
