 * The management OCP cluster must have default storage class. [Storage Configuration Documentation](https://docs.openshift.com/container-platform/4.12/post_installation_configuration/storage-configuration.html) Example of how to set a default storage class: `oc patch storageclass ocs-storagecluster-ceph-rbd -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'`

+* A network MTU of 9000 or larger on the OCP cluster hosting the KubeVirt VMs is recommended for optimial network performance. Smaller MTU settings will work, but network latency and throughput of the hosted pods will be impacted. Multiqueue should only be enabled on NodePools when the MTU is 9000 or larger.
