Thanks Michal, php version I used.

$xml = new SimpleXMLElement($lv->domain_get_xml($res)) ;
$data = $xml->xpath('//channel/target[@name="org.qemu.guest_agent.0"]/@state') ;

This error message is "harmless" in a sense that there is no split brain
of states between libvirt and QEMU. But yeah, your API is going to fail.

You can check for the agent status in the domain XML, for instance with
the following (rewrite in your favorite language):

virsh dumpxml fedora | xpath -e "string(//channel/target[@name='org.qemu.guest_agent.0']/@state)"
