Add an extension to the NUMA filter scheduler for host memory bw

Registered by Sudipta Biswas on 2015-06-24

We have added a spec in liberty to collect the memory bandwidth utilization on a given NUMA node.
The spec can be found here: https://review.openstack.org/#/c/180983/

The spec initially consisted of writing an extension to the NUMA topology scheduler filter
but was scoped out into a seperate BP.

In order to make use of the data updated for the host memory bandwidth utilizations on each NUMA node, an extension could be written to the existing numa_topology_filter that could make use of this data and do the necessary filtering of NUMA nodes based on the aforementioned attribute.

Unapproved for liberty due to the Non-Priority Feature Proposal Freeze. --johnthetubaguy 16th July 2015

Does this actually need more code? What is left to do? -- mriedem 20151008

mriedem - no code was merged for this during the liberty cycle. - sbiswas7 20151009

As there is no code up for review, removing this blueprint from mitaka, as part of the non-priority Feature Freeze. For more details please see: http://docs.openstack.org/developer/nova/process.html --johnthetubaguy 2015.01.15
