Before you install OpenShift Virtualization, ensure that your OpenShift Container Platform cluster meets the following requirements:
Your cluster must be installed on bare metal infrastructure with Red Hat Enterprise Linux CoreOS workers.
Shared storage is required to enable live migration.
You must manage your Compute nodes according to the number and size of the virtual machines that you want to host in the cluster.
To deploy OpenShift Virtualization in a disconnected environment, you must configure Operator Lifecycle Manager on restricted networks.
To use proxy with OpenShift Virtualization, you must configure proxy support in Operator Lifecycle Manager.
If your cluster uses worker nodes from multiple CPU vendors, live migration failures can occur. For example, a virtual machine with an AMD CPU might attempt to live-migrate to a node with an Intel CPU and likely fail migration. To avoid this, label nodes with a vendor-specific label, such as Vendor=Intel or Vendor=AMD, and set node affinity on your virtual machines to ensure successful migration. See Configuring a required node affinity rule for more information.
OpenShift Virtualization works with OpenShift Container Platform by default, but the following installation configurations are recommended:
Configure monitoring in the cluster.
