[openstack-dev] [nova] nova aggregate and nova placement api aggregate
Recently, i am trying to implement a function which aggregate nova hypervisors rather than nova compute host. But seems nova only aggregate nova-compute host. On the other hand, since Ocata, nova depends on placement api which supports aggregating resource providers. But nova-scheduler doesn't use this feature now. So is there any better way to solve such issue? and is there any plan which make nova legacy aggregate and placement api aggregate cloud work together? -- Regards, Jeffrey Zhang Blog: http://xcodest.me __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

There are some new features in Rocky [1] that involve resource provider aggregates for compute nodes which can be used for scheduling and will actually allow you to remove some older filters (AggregateMultiTenancyIsolation and AvailabilityZoneFilter). CERN is using these to improve performance with their cells v2 deployment. -- Thanks, Matt __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
