Hi every one;
when I want to place a new scheduling policy which code I have change on openstack?
Hi Fares, does this help you? http://docs.openstack.org/kilo/config-reference/content/section_compute-scheduler.html
Thank you very much Evan for your help. but my scheduler can integrate it in nova.conf file?and language used in Openstack is Python only, isn't?
That's right, you make changes to the scheduler in nova.conf. And yes, OpenStack is primarily Python.
Here is some more information about developing your own scheduling driver: http://docs.openstack.org/openstack-ops/content/customize.html: "Customizing the OpenStack Compute (nova) Scheduler".
