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.

  • 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:
