Hey, You can do more dynamic distribution during initial scheduling through a metric weighter. This question has been already raised and very well explained by Sean some time ago in this thread: https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack....

Hello,
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
Thank you for your time and input. Best regards,
Pierre
