I am exploring the potential for resource consolidation from the initial placement perspective, specifically within the filter scheduler. From my research, I understand that OpenStack Watcher can addresses consolidation in a dynamic manner (monitoring resource usage and using live migration), while consolidation in nova seems to rely on a static overcommitment ratio, without accounting for real resource usage.
Has dynamic overcommitment been considered for the initial placement phase? If not, I would like to propose implementing such a feature and would greatly appreciate any feedback or guidance from the community on this idea. Specifically, a custom filter could be interfaced with a monitoring stack to deploy servers as long as some thresholds are not exceeded
