              <nvpair id="rsc-default-1" name="resource-stickiness" value="100"/>
              <nvpair id="rsc-default-2" name="migration-threshold" value="10"/>

              <nvpair id="op-default-1" name="timeout" value="30s"/>
            </meta_attributes>
          </op_defaults>
        </configuration>
        <status/>
      </cib>
   
In the above example, we have one resource (an IP address) that we check
every five minutes and will run on host ``c001n01`` until either the
resource fails 10 times or the host shuts down.
