Your
ip netnsoutput doesn't show any qrouter-router-id namespace. That is a symptom of broken system. What is yourneutron router-listoutput ?Please format your text. What reports:-
$ps -ef | grep dhcp
Similar report for your qdhcp-xxxxxxx namespace :-
Link to sample
Please, also provide /var/log/neutron/dnsmasq.log
I haven't added a router yet, as I want to fix the vm dhcp ip issue first. Thanks Danlzack.
ps -ef | grep dhcp
The instance network is 192.168.8.0/24.
(more)Just find error in openvswitch-agent.log
Seems like GRE tunnel is NOT working, does this Centos kernel version support ovs GRE?
