Sorry, my bad.
The more free RAM is better (cost is smaller) thanks to this -1.0. So
the default behavior is spread-first indeed. To make it fill-first,
you can add flag --compute_fill_first_cost_fn_weight=1.0 to scheduler
node.
Kind regards, Yuriy.

I thought the defa
Fill-first cost function returns the amount of free RAM. By default it
is negated (multiplied by -1.0), so the less free RAM is better.
I think, this is a bit misguiding, but was changed right before Essex
(see https://bugs.launchpad.net/nova/+bug/965732 ).
