Description of problem: This RFE is part of the request is to introduce logic in the fencing workflow for the engine to determine if an inability to communicate with external hosts is because it is having network connectivity issues, or if there is a legitimate problem with the remote host. We should track the physical devices (i.e., interface, bond) used to establish connectivity from Engine to the hosts in the 'rhevm' logical network. In the event of a physical connectivity problem of an interface, we should be able to alert that so that the fencing flow will take that into consideration and allow the environment time to stabilize/reestablish connectivity with the hosts.
