Pods stuck on 'ContainerCreating' when redhat/openshift-ovs-multitenant enabled



Hi,
I tried to install OCP 3.11 with following variables set.
openshift_use_openshift_sdn=true
os_sdn_network_plugin_name='redhat/openshift-ovs-multitenant’

Some pods stuck on ‘ContainerCreating’.
[root buzz1 openshift-ansible]# oc get pods --all-namespaces
NAMESPACE               NAME                                    READY     STATUS              RESTARTS   AGE
default                 docker-registry-1-deploy                0/1       ContainerCreating   0          5h
default                 registry-console-1-deploy               0/1       ContainerCreating   0          5h

openshift-sdn           ovs-ff7r7                               1/1       Running             0          5h
openshift-sdn           sdn-7frfw                               1/1       Running             10         5h
openshift-web-console   webconsole-85494cdb8c-s2dnh             0/1       ContainerCreating   0          5h

Run ‘oc describe pods’, I got something as below.

  Normal   SandboxChanged          2s (x8 over 2m)  kubelet, buzz1  Pod sandbox changed, it will be killed and re-created.

How could I resolve this problem?
Any thoughts?

Thanks,
Jared
