	    1) Validate that required openstack service is up and running.
	    2) Validate that compute node is being created and get compute node name by using "sudo cord prov list".
	    3) From CORD-Test container, use python-neutron client and create network with name - NetA with an IP as local management  network.
	       (neutron net-create net-A-management, neutron subnet-create net-A-management 172.27.0.0/24 -gateway 172.27.0.1).
	    4) Now boot image in the same created network using nova boot image command (example given below :-
		 nova boot --image 3e2d7760-774a-4a16-be07-aaccafa779b6 --flavor 1 --nic net-id=8bc19377-f493-4cad-af23-45fb299da9de --nic net-id=8bc19377-f493-4cad-af23-45fb299da9de net-A-vm-01
	    5) Wait till VM boots up and starts running.
	    6) Verify that a VM is launched and running by using novaclient python API.
	    7) Create a virtual interface with vlan tag and local management floating ip on VM.
	    8) Create a same virtual interface with valn tag and any local management floating ip on head node.
	    9) Now ping to the VM from head node network which are launched a openstack service.
	   10) verify that ping is successful
	   11) Verify that flow is being added in ovs-switch in compute-node.
	   12) Verify that onos-ml2 plugin syncs through ReST call  from openstack service neutron.
	   13) Verify that cord-onos pushed flows to OVS switch.
	   14) Delete a br_int bridge and repeat steps 9 to 13, (it should not ping)
	   15) Add br_int bridge and repeat steps 9 to 13, (it should ping)
