Title:
  DHCPv6 assigned address is not added to VM's interface

Status in cloud-init:
  Expired

Bug description:
  Description of problem:

  Created a Nova instance with 2 NICs, with NIC 2 defined on StorageNFS
  network IPv6  address.  VM was created successfully with the correct
  interface config settings, however the Nova assigned IP address was
  not added to NIC 2 interface.

  Version-Release number of selected component (if applicable):

  How reproducible:
  100%

  Steps to Reproduce:
  1. Create StorageNFS network with IPv6 CIDR and address range defined
  2. Create a Nova instance with 2 NICs, 2nd NIC connected to StorageNFS network
  3. Login to VM and examin Eth1 IP address

  Actual results:
  The Nova assigned IPv6 address was not assigned to device Eth1

  Expected results:
  Expected the Nova assigned IP address to be assigned to Eth1 interface

  Additional info:
  Issue persisted with BOOTPROTO set to protocol, as well as when BOOTPROTO was removed from cloud.cfg
