I thought the default behavior in essex was spread-first:

From: 

https://github.com/openstack/nova/blob/stable/essex/nova/scheduler/least_cost.py#L41

    cfg.FloatOpt('compute_fill_first_cost_fn_weight',
             default=-1.0,
               help='How much weight to give the fill-first cost function. '
                    'A negative value will reverse behavior: '
                    'e.g. spread-first'),
    ]




Take care,
