So if someone wants to choose mogan for baremetal compute management, the recommended deployment is Mogan+Ironic for baremetals and Nova+Libvirt for VMs, this way we treat baremetals and vms as different compute resources. In a cloud with both vms and baremetals, it's more clear to have different set of APIs to manage them if users really care about what resources they got instead of just the performance. We also create a mogan horizon plugin which adds separated baremetal servers panel[1].

So Mogan does not use the placement service for tracking resources?
