+NOTE: If the HA resources of a positive resource affinity rule are currently
+running on different nodes, the CRS will move the HA resources to the node,

 However, suppose there are computationally expensive, and/or distributed
 programs running on the HA resources `vm:200` and `ct:300`, for example,
 sharded database instances. In that case, running them on the same node could
