The OpenShift Web Console does not display the correct IP addresses for Virtual Machines using multiple network interfaces, specifically when combining the default Pod network, Cluster User Defined Networks (CUDN), and secondary networks with localnet topology.

Environment

• Platform: OpenShift Container Platform (OCP) 4.19

• Operator: OpenShift Virtualization (CNV) 4.19.15

• Networking Plugin: OVN-Kubernetes

• Interface Count: 3 (1x Pod Network, 1x CUDN, 1x NAD Localnet)

Steps to Reproduce

1. Create a CUDN with Layer3 topology (Role: Secondary) as defined in the provided YAML.
2. Create a NetworkAttachmentDefinition (NAD) using ovn-k8s-cni-overlay with localnet topology.
3. Deploy a Virtual Machine with three interfaces mapping to:

• default pod network.

• first-cudn (ClusterUserDefinedNetwork).

• br-ex-network (NAD localnet).

Navigate to the Virtualization -> VirtualMachines -> [VM Name] -> Network Interfaces tab in the OpenShift Console.

Expected Behavior

The console should display the assigned IPv4 (and IPv6, if applicable) for all three interfaces. Specifically:

• The Pod Network interface should show the assigned cluster-internal IP.

• The CUDN interface should show the IP assigned from the 10.100.0.0/16 range.

• The Localnet interface should show the actual IP assigned via the external bridge/DHCP.

Actual Behavior

• Pod Network: The IP address is missing/blank in the dashboard view.

• CUDN Interface: Does not display the real assigned IP.

• Localnet Interface: Displays an incorrect/link-local IPv6 address instead of the primary IP address.
