Where do you suggest as the best place for such a service?

 Hi,

 I would like to bring Dynamic VM Consolidation capability into Nova. That
 is I would like to check compute nodes status periodically (let's say every
 15 minutes) and consolidate VMs if there is any opportunity to turn off
 some compute nodes.

 Any hints on how to get into this development process as part of nova?


 While I like the idea of having dynamic VM consolidation capabilities
 somewhere in OpenStack, it doesn't belongs in Nova. This service should
 live outside of Nova and just consume Nova's REST APIs. If there is some
 piece of information that this service would need that isn't made available
 via the REST API, we can fix that.



 Thanks,
 Mehdi

If we define a parameter like 'consolidation degree' and consolidate based
on this factor, we can achieve both objectives with an implementation.
There is an attempt by OpenStack neat project, but it is not integrated
into OS.

 I'd be interested in the opposite, the ability to rebalance the vm's
 across the fleet to even out load. Agreed it should live outside of Nova tho
