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
conf file appeas in this output<br>
* ip netns - to get the list of namespaces<br>
* ip netns exec <the_right_dhcp_namespace_name>
tcpdump -i any ... - to look for the dhcp offer or arp
issues<br>
* ping each other - instance to dhcp address, and vice
versa (the second one should be done from within the
namespace)<br>
