Placement is a separate service, independent of Nova. It tracks Ironic nodes as individual resources, not as a "pretend" VM. The Nova integration for selecting an Ironic node as a resource is still being developed, as we need to update our view of the mess that is "flavors", but the goal is to have a single flavor for each Ironic machine type, rather than the current state of flavors pretending that an Ironic node is a VM with certain RAM/CPU/disk quantities.
