--- deprecations: - | The ``os-hosts`` API is deprecated as of the 2.43 microversion. Requests made with microversion >= 2.43 will result in a 404 error. To list and show host details, use the ``os-hypervisors`` API. To enable or disable a service, use the ``os-services`` API. There is no replacement for the `shutdown`, `startup`, `reboot`, or `maintenance_mode` actions as those are system-level operations which should be outside of the control of the compute service.
