For Dublin release there is a workaround for providing OVN address in the configmap for the K8sPlugin. Updated the wiki with this information. Also copied here.
The master branch for k8sPlugin is under active development and it is not tested. It would be better just to stick to the release version of the K8s plugin.
Workaround for R4 Dublin. This step will not be needed in R5.
Edit the configMap helm-release-name-multicloud-k8s for K8s plugin to make changes to the config like below to add ovn-central-address:
{
"ca-file": "/opt/multicloud/k8splugin/certs/root_ca.cer",
"server-cert": "/opt/multicloud/k8splugin/certs/multicloud-k8s.pub",
"server-key": "/opt/multicloud/k8splugin/certs/multicloud-k8s.pr",
"password": "c2VjcmV0bWFuYWdlbWVudHNlcnZpY2VzZWNyZXRwYXNzd29yZA==",
"database-type": "mongo",
"database-address": "multicloud-k8s-mongo",
"etcd-ip": "multicloud-k8s-etcd",
"plugin-dir": "/opt/multicloud/k8splugin/plugins",
"ovn-central-address": "<IP address of the Kubernetes controller>:6641"
}
(the configMap is based on oom/kubernetes/multicloud/charts/multicloud-k8s/resources/config/k8sconfig.json )
Restart the Multoclod-K8s Plugin for the changes to take effect.

Hi Ritu,
Can you check? Could this be due to not using default namespace in helm charts?

Hi again,
I've managed to launch some more basic tests today and it looks like my change doesn't fix this issue completely. It fixes creating network resources and they are created correctly (please see log below), however pods are having issues with creating sandbox
due to multus issues. Nevertheless I think that pod sandbox issue may have root cause anchored somewhere else, so probably additional fix may be needed.

Hi Łukasz, All
I came across the same issue as you today. I think I've located culprit of this error and I've addressed it in review
https://gerrit.onap.org/r/c/multicloud/k8s/+/91812.
Please note it's work in progress as I didn't manage today to thoroughly test it, but I expect to do it tomorrow morning.
With Regards,
Konrad Bańka
