[Bug 1815793] [NEW] 'nova hypervisor-servers' returns unexpected results when working with Ironic
Public bug reported:
Description
===========
I have a baremetal environment using Nova to schedule on top of four Ironic baremetal nodes. I successfully deployed an instance to one of those nodes. Then I ran 'nova hypervisor-servers' against each of the nodes, and the instance showed up against every node.
Steps to reproduce
==================
After registering the nodes in Ironic and creating the server, I can see that the server is deployed on a single Ironic node:

Then, if I run 'nova hypervisor-servers', the one instance shows up for
multiple nodes:
