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.

Just note that since Essex release Nova by default use fill-first cost
function, meaning that nodes with less free RAM will be preferred for
new instances.
Kind regards, Yuriy.

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

Hi,
Me and my colleague are doing research about openstack and energy
efficiency during part of our master thesis about cloud computing. And
mayby we would like to write something inside nova-scheduler to dynamically

Hi Szymon,
This is a really great that you are working for energy efficiency
datacenter. whatever the topics you mentioned that really affects for
efficient data center. I would like to add some points on this. You should
consider Quantum project to deploy and research for datacenter. Distributed
