Hello again,

I'm still trying to makes ovn works with k8s bootstrapped by kubeadm.

I've been successfull at starting all daemons without errors.

Watchers are running, however, no mac address are shown when doing 
ovn-nbctl show, only the ports.

kube-dns fails to start cause it cannot reach the kube-apiserver.

I'm wondering how to debug this ?

Here's a, example of output, only the infrastructure setup by the 
scripts are showing mac addresses :
