When using a migration network, the populator pod is stuck in ContainerCreating state and this event is logged:

OCP 4.17

Always

1. Create a NAD for the migration:

apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
  annotations:
    forklift.konveyor.io/route: 10.37.201.254
  name: mtv-migrations
  namespace: openshift-mtv
spec:
  config: |
    {
            "cniVersion": "0.3.1",
            "name": "ovn-localnet-1",
            "type": "ovn-k8s-cni-overlay",
            "topology": "localnet",
            "netAttachDefName": "openshift-mtv/mtv-migrations",
            "subnets": "10.37.200.0/23"
    }


2. Configure the OCP provider to use the network:

apiVersion: forklift.konveyor.io/v1beta1
kind: Provider
metadata:
  annotations:
    forklift.konveyor.io/defaultTransferNetwork: openshift-mtv/mtv-migrations
  name: host
  namespace: openshift-mtv
spec:
  secret: {}
  type: openshift
  url: ""


3. Run a migration

Populator pod stuck in ContainerCreating, with FailedCreatePodSandBox events logged.

The populator pod has the 'v1.multus-cni.io/default-network' annotation:

apiVersion: v1
kind: Pod
metadata:
  annotations:
    k8s.ovn.org/pod-networks: '{"default":{"ip_addresses":["10.129.2.159/23"],"mac_address":"0a:58:0a:81:02:9f","gateway_ips":["10.129.2.1"],"routes":[{"dest":"10.128.0.0/14","nextHop":"10.129.2.1"},{"dest":"172.30.0.0/16","nextHop":"10.129.2.1"},{"dest":"169.254.169.5/32","nextHop":"10.129.2.1"},{"dest":"100.64.0.0/16","nextHop":"10.129.2.1"}],"ip_address":"10.129.2.159/23","gateway_ip":"10.129.2.1","role":"primary"}}'
    openshift.io/scc: forklift-controller-scc
    seccomp.security.alpha.kubernetes.io/pod: runtime/default
    v1.multus-cni.io/default-network: openshift-mtv/mtv-migrations

- No errors creating the pod.
- Migration performed over the defined network.

Looks like this change is missing in v2.7:
