That was referring to the introspection stage. From what I can tell you are experiencing issues during deployment as it fails to provision the nova instances, can you check if during that stage the nodes get powered on? 

Make sure that before overcloud deploy the ironic nodes are available for provisioning (ironic node-list and check the provisioning state column). Also check that you didn't miss any step in the docs in regards to kernel and ramdisk assignment, introspection, flavor creation(so it matches the nodes resources)

No, the nodes details should be enough.

> And which log files should I watch during deployment?

You can check the openstack-ironic-conductor logs(journalctl -fl -u openstack-ironic-conductor.service) and the logs in /var/log/nova.
