Comment 5 for bug 1817833

Having said that, I see something missed in the fix for bug 1756179 here:

https://github.com/openstack/nova/blob/b9bcbab86b8314fbaaeb2d2af6282d4a612aeb8d/nova/api/openstack/compute/services.py#L270

That does not account for ironic where the compute service could be managing more than one node and will only delete the resource provider in placement for the first compute node in the list:
