[openstack-dev] [nova] schedule instance based on CPU frequency ?

CPU frequency is an import performance parameter, currently nova drivers
just report cpu_info without frequency. we stored the compute node
cpu_info in database with colum compute_nodes.cpu_info, we can add the
The usage of cpu frequency I can think is used to schedule to meet
applications which need high frequency. add a frequency based filter ?
if we need this , I would like to propose a spec for this .
There are two steps to leverage cpu frequency:
1. report cpu frequency and record the value, nova hypervisor-show will
include the value .
2. filter compute nodes based cpu frequency.
add a new scheduler filter to do that
before I start to do these stuff. I would like to your input .
Do we need leverage CPU frequency in Nova ?
if yes, do we need a new filter or leverage existing filter to use
