Fixed In Version: openstack-nova-2014.1-3.el7ost Doc Type: Enhancement
Doc Text:
With this update: * Weights have been normalized in OpenStack Compute so that there is no need to artificially inflate multipliers. The maximum weight that a weigher puts for a node is 1.0, and the minimum is 0.0. * A new multiplier option, 'offset_weight_multiplier' (nova.cells.weights.weight_offset.WeightOffsetWeigher), has been introduced. * Stacking flags for weighers have been introduced. Negative multipliers should not be using for stacking, but the weighers are still compatible (they issue a deprecation warning message).

We probably shouldn't be linking gerrit reviews in release note text, my bad.

Comment 4 Russell Bryant 2014-04-01 13:52:24 UTC
Updated doc text to reflect the changes that did not merge into Icehouse
