Can you please share the output of
 source /etc/ovirt-hosted-engine/hosted-engine.conf
 find /rhev/data-center/ -path
"*/${sdUUID}/images/${conf_image_UUID}/${conf_volume_UUID}" -type f -exec
sh -c 'sudo -u vdsm dd if=$1 2>/dev/null | tar -xOvf - vm.conf
 2>/dev/null' {} {} \;
executed on your first host?
