From the logs, I can see the quick hint actually works in terms of solving the management server's complain about vc cert thumbprint issue you mentioned before. Now the issue changes to how to update the vc certs information on the controller nodes easier. Thanks for this good question and we will improve in the next versions or patches. For now, unset vmware_ca_file from cinder.conf file will remove the cinder's complain. Another potential issue you mentioned is VIO VM does not startup sometimes, could you past a console screenshot when you meet it next time?
Thanks,
Jun
