The following command creates a fence device instance for an RHEV-M REST API device:
ccs -f cluster.conf --addfencedev rhevmtest1 agent=fence_rhevm ipaddr=192.168.0.1 login=root passwd=password123 \
 power_wait=60 ssl=on
The following is the cluster.conf entry for the fence_rhevm device:

 <fencedevices>
  <fencedevice agent="fence_rhevm" ipaddr="192.168.0.1" login="root" name="rhevmtest1" passwd="password123" \
   power_wait="60" ssl="on"/>
 </fencedevices>
