it worked in 4.10 as there was no explicit check on single vs dual stack. Since this fix "https://github.com/kubevirt/ssp-operator/commit/b9ad74a8c52f22993e62de937c6e0deae38fbc4a" , there has been a hardcoded configuration for IPv4 which is causing the failure Spec: v1.ServiceSpec{ InternalTrafficPolicy: &policyCluster, IPFamilies: []v1.IPFamily{v1.IPv4Protocol}, IPFamilyPolicy: &familyPolicy, Ports: []v1.ServicePort{ { Name: metrics.MetricsPortName, Port: 443, Protocol: v1.ProtocolTCP, TargetPort: intstr.FromString(metrics.MetricsPortName), }, }, Selector: map[string]string{ metrics.PrometheusLabelKey: metrics.PrometheusLabelValue, "name": OperatorName, }, SessionAffinity: v1.ServiceAffinityNone, Type: v1.ServiceTypeClusterIP, }, Petr, do you know if CNV should support single stack IPV6? If not, we need to generate new alert, if yes it will be completely different discussion. Hey. We do not support single-stack IPv6. The feature is tracked in https://issues.redhat.com/browse/CNV-14598 and not pinned to any release. The decision is to improve on error raised, so it's not as cryptic as of now. Tested with: OCP-4.14.0-0.nightly-2023-09-20-033502 CNV-v4.14.0.rhel9-2040 Installing CNV operator on the single stack IPv6 OCP cluster, throws the critical alert - "SingleStackIPv6Unsupported KubeVirt Hyperconverged is not supported on a single stack IPv6 cluster" With this observation moving this bug to VERIFIED Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Important: OpenShift Virtualization 4.14.0 Images security and bug fix update), and where to find the updated files, follow the link below.

Description of problem: Openshift Virtualization does not currently support single-stack ipv6 and should fail immediately with an error stating that. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Configure shift for single-stack ipv6 2.
