[Pacemaker] fence_rhevm (fence-agents-3.1.5-25.el6_4.2.x86_64) not working with pacemaker (pacemaker-1.1.8-7.el6.x86_64) on RHEL6.4

Mine is:
<primitive id="Fencing" class="stonith" type="fence_rhevm">
<instance_attributes id="Fencing-params">
<nvpair id="Fencing-ipport" name="ipport" value="443"/>
<nvpair id="Fencing-shell_timeout" name="shell_timeout" value="10"/>
<nvpair id="Fencing-passwd" name="passwd" value="{pass}"/>
<nvpair id="Fencing-ipaddr" name="ipaddr" value="{ip}"/>
<nvpair id="Fencing-ssl" name="ssl" value="1"/>
<nvpair id="Fencing-login" name="login" value="{user}@{domain}"/>
</instance_attributes>
<operations>
<op id="Fencing-monitor-120s" interval="120s" name="monitor" timeout="120s"/>
<op id="Fencing-stop-0" interval="0" name="stop" timeout="60s"/>
<op id="Fencing-start-0" interval="0" name="start" timeout="60s"/>
</operations>
</primitive>
Maybe ipport is important?
Also, there was a RHEVM API change recently, I had to update the fence_rhevm agent before it would work again.
