This means the nova-compute services are not all configured properly to
report into the placement service. Docs are available here:

https://docs.openstack.org/developer/nova/placement.html

https://docs.openstack.org/ocata/install-guide-ubuntu/nova-compute-
install.html

So for example, if you run "nova service-list" and there are 4 nova-
compute services listed, those need to all be reporting inventory data
into the placement service, so the [placement] section of nova.conf on
each compute host has to be configured properly, etc.

Title:
  ` nova-status upgrade check` Warning

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description
  ===========
  When I execute the command `nova-status upgrade check`,
  output:
  +---------------------------------------------------------------------+
  | Upgrade Check Results                                               |

  | Check: Resource Providers                                           |
  | Result: Warning                                                     |
  | Details: There are 1 compute resource providers and 4 compute nodes |
  |   in the deployment. Ideally the number of compute resource         |
  |   providers should equal the number of enabled compute nodes        |
  |   otherwise the cloud may be underutilized. See                     |
  |   http://docs.openstack.org/developer/nova/placement.html           |
  |   for more details.                                                 |
  +---------------------------------------------------------------------+

  I deploy the `nova-placement-api` in the controller node.
  What I will deploy, that is to avoid the `Resource Providers Warning`. multi nova-placment-api or what ?
