    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.<br>
    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?<br>

              I would start with:<br>
              * ps -efl | grep dnsmasq | grep -v grep - to verify that
              the dnsmasq process is running, you can also check the
