This is seen on both vSphere and Baremetal impacting all dhcp IPAM usecases. This is regression as well as new feature. So the dhcp ipam was introduced in 4.0-4.1 but managing it via CNO was introduced in 4.2. No matter you do it via CNO or manually via net-attach-def, its causing pod creation fail Verified it on v4.3.0-0.ci-2019-10-04-083724. Will re-test it when the v4.3 nightly image ready on https://openshift-release.svc.ci.openshift.org/ Verified it on 4.3.0-0.ci-2019-10-09-120159 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
