Any chance you can try to provide some more information? Perhaps a tcpdump dump (something like 'tcpdump -i any -w /root/dump1', or '-i NIC' if you know which NIC, perhaps also 'port 53' if it's just that)? From both hosts and the dns server? Perhaps /var/log/vdsm/* and /var/log/ovirt-hosted-engine-ha/* from hosts?
