Yes, but please note: in spite of having plenty capacity at every node, 
utilization prevented to (re)start one. Originally the stonith resources 
hadn't got memory capacity set, but after setting those to explicit zero, 
the resource still wasn't started. Only disabling placement strategy 
helped. One type of capacity is defined alone.

At the moment utilization is disabled and "crm_simulate -U -L" produces:
