Hypervisor fencing didn't work as expected
Environment
Red Hat Enterprise Virtualization 3.2
Issue
Why didn't the hypervisors fence each other when the rhevm network was disconnected?
Resolution
Fencing cannot occur if the RHEV-M cannot reach any hosts.
Root Cause
The RHEV-M decides what gets fenced. When it does so, it instructs one of the hosts to perform the fencing action. Therefore, if the RHEV-M is unable to reach any of the hypervisors, it cannot instruct them to perform fencing.
