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
