Contrail: DHCP doesnt work from VM

DHCP doesnt work from VM

1)	Check http://<compute-ip>:8085/Snh_ItfReq?name=<tap_name> 
  a.	If vif status is not active then it’s a known corner case issue with agent and afaik vrouter-agent restart is the only way to recover.
  b.	if vrf_name/vn_name or other config shows -error- then the configs weren’t downloaded from control-node
    i.	get the active control node via http://<compute-ip>:8085/Snh_AgentXmppConnectionStatusReq? With cfg_controller ‘yes’
    ii.	Check whether vmi has vmi-ri,vn,instance-ip as neighbor under ifmap in control http://<control-ip>:8083/Snh_IFMapTableShowReq?table_name=virtual-machine-interface
    iii. If not found, do ‘netstat -antp | grep <control-process-id> | grep 8443’ and find the connected ifmap server
    iv.	On the ifmap-server do ‘curl -uadmin:contrail123 http://127.0.0.1:8095/virtual-machine-interface/<vmi-id> | python -m json.tool’ and check for vn, ri refs
    v.	If refs not found, check for schema.err on the active schema node around the vmi create timestamp.
    vi.	If no errors, check the rabbitmq connection between config and check the vnc_config queue under ‘rabbitmqctl list-queues’ for any undelivered messages
