⁠7.5. CPUs

Each cluster is configured with a minimal CPU type that all hosts in that cluster must support. Guests running on hosts within the cluster all run on this CPU type, ensuring that every guest can be migrated to any host within the cluster.
Red Hat Enterprise Virtualization has a set of supported CPU types to choose from when configuring a cluster.
