Empty output from "ip netns" can be either not using namespaces (run 
grep "use_namespaces /etc/neutron/l3_agent.ini" to find out) or using 
wrong iproute package.
Could you please also check what does tcpdump report? could you see the 
discover on the dhcp nic (when using ovs it's a tapxxxxxxxx-xx nic)? 
could you see an offer sent from that nic?
