I'm using corosync instead of qdiskd. And here's my cluser.conf, it
looks really simple:

<?xml version="1.0"?>
<cluster name="ckvm1_pod1" config_version="5">
    <clusternodes>
    <clusternode name="***.host1.ckvm1.***" votes="1" nodeid="1">
      <fence>
        <method name="single">
          <device name="host1_ipmi"/>
        </method>
      </fence>
    </clusternode>
    <clusternode name="***.host2.ckvm1.***" votes="1" nodeid="2">
      <fence>
        <method name="single">
          <device name="host2_ipmi"/>
        </method>
      </fence>
    </clusternode>
  </clusternodes>
  <fencedevices>
    <fencedevice name="host1_ipmi" agent="fence_ipmilan" ipaddr="***" login="***" passwd="***"/>
    <fencedevice name="host2_ipmi" agent="fence_ipmilan" ipaddr="***" login="***" passwd="***"/>
  </fencedevices>
  <rm>
    <failoverdomains/>
    <resources/>
  </rm>
</cluster>
