    Repeat the same for SG neutron_to_vnc()
2) In contrail-api.conf add these to DEFAULT section
    subnet_allocator_write=cassandra
    subnet_allocator_read=cassandra
    list_optimization_enabled=True
3) Increase the FD limits in /etc/contrail/supervisor_openstack.conf (min_fds) and /etc/default/neutron-server (ulimit -n ),
    for rabbitmq-server: /etc/default/rabbitmq-server (ulimit -n)
4) other sysctl tweaks

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.
