Configuring several interface will cause /usr/local/bin/configure-ovs.sh to "loop" adding 15 minutes to boot time.  This will cause kubelet to NOT start requiring manual intervention.

Always

1. Add 15 or more interfaces, of any type, to network config. This can be done via install or post install nmstate.
2. Restart node.
3. Observer /usr/local/bin/configure-ovs.sh cycles through adding interfaces but stalls after 10 or so and sleeps for 90s between adding each interface. Having 20 or more interface can cause Kubelet to not start.
