Everything worked very well before. Suddenly we hit the issue that vm instances could not get ip addresses from dhcp agent.  I looked into dhcp-agent.log, but didn’t find much useful information. Just wondering if someone could shed some light on this issue.

When I use tcpdump –i br-ehter1, or tcpdump –i < physical Ethernet port id>, I was able to see the DHCP requests, but no reply from dhcp agent.
