The starlingx may be running with an external keystone for authentication, so I plan to stop itself keystone and use haproxy to connect the external. I think it is ugly，but I don’t know other ways to achieve this requirement.

Maybe a bit off topic, have you consider keystone federation? FYI.

Also sm-unmanage tells SM not to attempt to monitor the service. Sm will always show the service in good working condition. once you run sm-unmanage service <service>, you can mange the service yourself. SM will regain control to the service after reboot or you run "sm-manage service <service>".
