Yes. If I understood correctly. Just setup a clone with
clone_node_max set to 1. And an extra constraint to make room for
the other resource which would say "don't run these two on the
same node". Furthermore, make sure that the score for the
loadbalancer resource is always higher than for the clone.

Not sure to what do you refer.
