Shutdown Openstack HA VM from VM itself?
I want to be able to shutdown an Openstack VM node, especially those from Prometeus within the node itself so that the HA option doesn't bring it back up. Is there someway to accomplish it within the node itself?
Would that require accessing the API from the node itself, or can some feature be set within the node itself which the HA system can detect and avoid bringing it back up again?

In a typical setup, failover will only occur when the host node appears to have failed, not when individual virtual machines look as though they are offline. Shutting down normally (shutdown -h 0) should not result in a failover action.
Is
shutdown -h 0the same asshutdown -h now?Yes, you define time in seconds when would you like the server to shut down.
