It turned out dhcp tests work only because agents are considered dead after 10 seconds while they report to server every 60 seconds. This led to calling network resync after agent revival and hiding the fact dhcp agent is not capable of receiving any amqp messages. This patch sets the report interval of agents to the half of agent_down_time on server side and uses eventlet dhcp agent in order to trigger eventlet monkey patching code. Eventlet was behind the failure with messages not getting processed. As [1] notes: "Note: If the “eventlet” executor is used, the threading and time library need to be monkeypatched." Because each port calls dhclient to obtain IP address and each dhclient instance overwrites /etc/resolv.conf there was added a script that generates fullstack-dhclient-script from an existing dhclient-script before starting fulltstack tests. This generated script is passed to each dhclient process running in fake fullstack machine using -sf parameter.
