IP not assigned to service instances in service chaining.

[Shashikiran H]

Version: 3.1.0.0-2739 mitaka
Topo:
host1 = 'root@10.204.216.201'
env.roledefs = {
    'all': [host1],
    'cfgm': [host1],
    'openstack': [host1],
    'control': [host1],
    'compute': [host1],
    'collector': [host1],
    'webui': [host1],
    'database': [host1],
    'build': [host_build],
}

I create a v1 transparent service chain between left and right vm. There are 2 SI in between the vms.
IP address is not assigned to the service instances when I create transparent service chain. The addresses to the left and right vms are assigned correctly.

Did not find any schema crashes. I see flow drops with the error "short flow" when I ping from left to right vm because of this and no flows created in the agent.

It is seen that this happens with Vns created using VncApi
neutron net-list would not show the subnet associated with that VN
For vms booted with that VN, nova show would not show the IPs from the VN.

Same behavior is seen for SIs.
