Description
=====================
Finalize installation

Start the Compute services and configure them to start when the system boots:
In brief the document misses openstack-nova-consoleauth.service from enabling and starting .

the following commands are not correct

# systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
# systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

The correct ones are

# systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service openstack-nova-consoleauth.service
# systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service openstack-nova-consoleauth.service

I discovered the problem when trying to list the openstack hosts on controller node.
i found that openstack-nova-consoleauth.service is missing
So i had to start and enable the service to get it work

The bug is found while deploying openstack rocky release ( using CentOS )

As noted in the duplicated bug, the nova-consoleauth service is deprecated starting in Rocky, so you don't really need to install it if you're doing a fresh install, but you might still need it if doing an upgrade.
