Couple of things to check,

   - On controller in nova.conf you should have [placement] section with
   below info
      - [placement]
      os_region_name = RegionOne
      project_domain_name = Default
      project_name = service
      user_domain_name = Default
      password = <password>
      username = placement
      auth_url = <auth_url>
      auth_type = password
   - If nova service-list shows your nova-compute is UP and RUNNING, you
   need to run discover commands on controller as below
      - nova-manage cell_v2 map_cell0 --database_connection <db_url>
      - nova-manage cell_v2 simple_cell_setup --transport-url
      <transport_url>
      - nova-manage cell_v2 discover_hosts --verbose

Discover command should show message that it has discovered your compute
nodes. In case still instance launch fails check nova-conductor and
nova-scheduler logs for more info.

For more information refer,

Thanks,

Prashant
