Doc Text:	In Red Hat OpenStack Platform 16.0, a technology preview has been added to the Orchestration service (heat). A new parameter, `NovaSchedulerQueryImageType,` has been added that controls the Compute service (nova) placement and scheduler components query placement for image type (scheduler/query_placement_for_image_type_support). When set to true (the default), `NovaSchedulerQueryImageType` excludes compute nodes that do not support the disk format of the image used in a boot request. For example, the libvirt driver uses Red Hat Ceph Storage as an ephemeral back end, and does not support qcow2 images (without an expensive conversion step). In this case, enabling `NovaSchedulerQueryImageType` ensures that the scheduler does not send requests to boot a qcow2 image to compute nodes that use Red Hat Ceph Storage.	Story Points:	---

Description Dan Smith 2019-05-15 22:47:49 UTC

This was merged in Train:

https://blueprints.launchpad.net/nova/+spec/request-filter-image-types

We need to be able to enable it in director (probably by default) and it needs some easy QE:

Set up a deployment with Ceph and ideally one compute node without ceph, force_raw_images=False. Boot qemu image instances and make sure placement and scheduler are always choosing the non-ceph one. Also use osc-placement to validate that QCOW2 is present on non-ceph nodes, and absent on ceph ones.
