A VM/Host anti-affinity (or affinity) rule specifies the relationship between a group of virtual machines and a group of hosts. Anti-affinity rules force the selected virtual machines to remain hosted on different hosts during failover actions. You create the rules to enable a high availability for the Cloud Management Platform.
