Baremetal filters and default filters cannot be used simultaneously in the same nova

[Jiang]

Hello, my openstack version is pike.
There is only one nova-scheduler service in environment, but I have ironic nodes and kvm nodes.If I set use_baremetal_filters to True, I can only use baremetal_enabled_filters. If set use_baremetal_filters to False, I can only use enabled_filters.
Is there a way to use both filters at the same time? If I create ironic instance, use baremetal_enabled_filters. If I create vm instance, use enabled_filters.

No that's not supported. I'm not entirely sure how various deployments handle this issue, if it's separate compute API endpoints for VMs and BMs or how they handle a single nova installation doing both VMs and BMs besides using baremetal filters for specific host aggregates that use ironic. What is the intersection of filters that you need and which filters are mutually exclusive in your setup?

It probably helps to know that the baremetal filter stuff is deprecated starting in Pike (and removed in Rocky) since we have custom resource classes now and scheduling based on the Placement service.

Correction in comment #1, I meant "using specific baremetal flavors", not filters.
