I used devstack to set up my openstack ironic. After I added resources to a baremetal node, it reflected on the node however, no resourced showed up in hypervisor stats.

I tried following steps to synchronize the database:

•   nova-manage cell_v2 discover_hosts --by-service --verbose
•   nova-manage db sync
•   nova-manage api_db sync
•   restart placement services
•   restart nova services

But nothing helped.

Here are some of my troubleshoot command output. Any help is appreciated!
