Shi Xiong, Thanks for asking! The error was found in dnsmasq log during our test. The error looks something like: "no addresses available". Jian Li from my team posted a comment about the PID error on your code review: https://review.openstack.org/#/c/70649/15/neutron/agent/linux/dhcp.py You can search his name "jian li" on that page to find the comment. BTW, I volunteered myself on this Tuesday's meeting to help on the dnsmasq code, so we can get the comments addressed and make IPv6 functional ASAP. Please let me know what I can help with that.
