During a deployment of the control plane I kept hitting an issue where the deployment would hang at creating the DNSmasq service definition.  After beating my head against the failed deployment for longer than I care to admit, I found the error in the metallb-controller pod:

Nooba-STS and Nooba-s3 had been assigned IPs randomly from the Openstack subnet pools I had created.  The same IP I had intended to use for my ctlplane VIP(172.20.85.80) had been assigned to nooba-sts.  There were no obvious errors in the Openstack namespace and the deployment would just hang.  I had installed ODF prior to installing metallb or defining any IP pools.
