dnsmaq is running, ip netns doesn't return anything.
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?

Hi,
I gpt an instance UP but it doesnot get an IP address. neutron
agent-list lists DHCP agent happy. While booting I see cirros
stuck at sending discover... multiple times. dnsmasq process is
running. how do i debug?
I would start with:
* 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
* ip netns - to get the list of namespaces
* ip netns exec <the_right_dhcp_namespace_name> tcpdump -i any ...
- to look for the dhcp offer or arp issues
* ping each other - instance to dhcp address, and vice versa (the
second one should be done from within the namespace)
Thanks
