Re: [openstack-dev] Dynamic VM Consolidation Agent as part of Nova
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.

Re: [openstack-dev] Dynamic VM Consolidation Agent as part of Nova
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 BR, Stuart On Nov 19, 2014 12:15 AM, "Mehdi Sheikhalishahi" wrote: > Where do you suggest as the best place for such a service? > > On Tue, Nov 18, 2014 at 11:49 PM, Joe Gordon > wrote: > >> >> >> On Tue, Nov 18, 2014 at 7:40 AM, Mehdi Sheikhalishahi < >> mehdi.alish...@gmail.com> wrote: >> >>> 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.

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

[openstack-dev] Dynamic VM Consolidation Agent as part of Nova
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?
