Instances consolidation to achieve optimized resource allocation

Registered by Lorenzo Affetti on 2014-10-30

Operations on instances (create, delete, resize, etc.) are handled using nova-compute, nova-scheduler and nova-conductor.
The only moment in which operations are performed is when the user (or Heat in his place) asks it.
In this scenario, except for creation, nothing is done to automatically achieve a good (or optimized) resource allocation of instances on physical machines.
The idea is to add a new service (nova-consolidator) that reacts on precise events (e.g. delete, resize) and automatically consolidates instances performing live migrations.
The result should lead to a better usage of physical machines.
