How reproducible: ----------------- 100% Steps to Reproduce: ------------------- 1. Deploy disconnected BM IPI cluster with provisioning network IPv4 and baremetal network IPv6 Actual results: --------------- Deployment failed Expected results: ----------------- Deployment succeeded Additional info: ---------------- The upstream DNS server received via DHCP is later added to the /etc/resolv.conf The possible race is here: https://github.com/openshift/machine-config-operator/blob/master/templates/common/baremetal/files/NetworkManager-resolv-prepender.yaml#L29 when we do connection down ; connection up /var/run/NetworkManager/resolv.conf is empty; adding a 3 sec delay before and DNS server received via DHCP is there.
