…ures II When metal3-dnsmasq pod restarts during a node's DHCP lease renewal on the provisioning network (172.23.0.0/24), NetworkManager fails to renew and sets ipv4.method=disabled. NMState operator then preserves this disabled state, causing permanent loss of provisioning network connectivity on that node. The issue occurs when OpenStackProvisionServer and metal3 pods run on different nodes. If metal3 restarts while a node is attempting DHCP renewal, the temporary unavailability of metal3-dnsmasq causes the renewal to fail. Solution: Automatically detect the node running metal3 pod (via k8s-app=metal3 label) and configure provisionServerNodeSelector in baremetalSetTemplate to schedule OpenStackProvisionServer on the same node. This ensures provisioning network connectivity is maintained because metal3-static-ip-manager maintains a static IP (172.23.0.3) on the metal3 node regardless of dnsmasq restarts.
