 Once all the VMs are up and the ONOS apps are configured, XOS should be able to get an address mapping from the `virtualbng`
-ONOS app when creating a vCPE.  To test this, enter the XOS Docker container and run:
-
-```

-This will run the TOSCA engine with `subscriber.yaml`.  After a bit, a new VM should be created in slice *mysite_vcpe* running

 the appropriate *Vbng tenant* object in XOS.  It should contain an IP address in the 10.254.0.0/24 subnet.
