Are you sure you're stopping the nova-compute service before deleting
the actual service record via the API?

https://developer.openstack.org/api-ref/compute/#delete-compute-service

Otherwise the ResourceTracker in the compute process will recreate the
compute node.

The Service.destroy is called from the API here:

Which eventually calls the DB API to delete the associated compute node
record:

Title:
  Deleting a service with nova-compute binary doesn't remove compute
  node

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  If you are taking a nova-compute service out of service permanently,
  the logical steps would be:

  1) Take down the service
  2) Delete it from the service list (nova service-delete <uuid>)

  However, this does not delete the compute node record which stays
  forever, leading to the scheduler to always complain about it as well:

  2018-09-20 13:15:45.312 131035 WARNING nova.scheduler.host_manager
  [req-c4a7c383-c606-48a7-b870-cc143710114a
  234412d3482f4707877ca696e105bf5b acb15d2ffaae4eda98580c7b874d7f89 -
  default default] No compute service record found for host
  <snip>.vexxhost.net

  https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L716-L720

  We should be deleting the compute node if a nova-compute binary is
  deleted, or that section should automatically clean up while warning
  (because service records can be rebuilt anyways?)
