Redhat cluster fencing configuration with fence_rhevm

Hi,

I installed Redhat Cluster with corosync and pacemaker. I am trying to configure fancing device and I am using fence_rhevm device. I need to understand what is the port paramater. It says name of virtual machine but which virtual machine? I searched it google and Redhat web site but I couldnt get clear answer. Can anyone help me about this situation. Thanks.
