Thanks Jason, it seems similar to this. Since I'm running from devstack, I don't have a /etc/init/quantum-dhcp-agent.conf file. I checked though, and there are 2 instances of quantum-dhcp-agent running on the host (see below), but none are running for the right network. Still trying to debug why this is.
