All nova-manage command via tht are run as nova user, which is correct. If for some reason a manual nova-manage command was triggered on a controller as root user where no previous nova-manage command was run results in creating the nova-manage.log with root:root as owner. As a result subsequent overcloud deploy runs can fail like:
"Error running ['docker', 'run', '--name', 'nova_api_ensure_default_cell', '--label', 'config_id=tripleo_step3', '--label', 'container_name=nova_api_ensure_default_cell', '--label', 'managed_by=paunch', '-
