I tried with downstream 6.2.0.4, upstream carbon and Nitrogen pre-built tar too. I started the karaf, installed netvirt-sfc feature and checked contents of these files.
Also I did add netvirt-sfc feature to featuresBoot in org.apache.karaf.features.cfg and "service start odl". The content of these files dont match with what puppet configures when sfc feature is enabled.
These files content collide with that of auto-tunnel enablement.
