Hi Alioune, It is weird that when you create a port chain, you get a “chain delete failed” error message. We never had this problem. Chain deletion is only involved when you do “delete chain” or “update chain”. Not sure which networking code file combination you are using or whether it is because your system is not properly cleaned up or not properly installed. We are going to release the networking-sfc mitaka version soon. I would suggest that you wait a little bit and then use the official released mitaka version and reinstall the feature on your system.

I've installed OVS (Open vSwitch) 2.3.90 with Linux kernel 3.13.0-62 and the neutron L2-agent runs correctly. I followed the process by creating classifier, port pairs and port_group but I got a wrong message "delete_port_chain failed." when creating port_chain [2] I tried to create the neutron ports with and without the option "--no-security-groups" then tcpdpump on SFs tap interfaces but the ICMP packets don't go through the SFs.
