 * If your cluster uses worker nodes with different CPUs, live migration failures can occur because different CPUs have different capabilities. To avoid such failures, use CPUs with appropriate capacity for each node and set node affinity on your virtual machines to ensure successful migration. See xref:../../nodes/scheduling/nodes-scheduler-node-affinity.adoc#nodes-scheduler-node-affinity-configuring-required_nodes-scheduler-node-affinity[Configuring a required node affinity rule] for more information.
