[Bug 1377843] [NEW] Instances won't obtain IPv6 address and gateway when using Stateful DHCPv6 provided by OpenStack

 

Public bug reported:

Description of problem:
=======================
I Created an IPv6 subnet with:
1. ipv6_ra_mode: dhcpv6-stateful
2. ipv6_address_mode: dhcpv6-stateful

Version-Release number of selected component (if applicable):
=============================================================
openstack-neutron-2014.2-0.7.b3

How reproducible:
=================
100%

Steps to Reproduce:
===================
1. create a neutron network
2. create an IPv6 subnet:
# neutron subnet-create <IPv6_net_id> 2001:db2::/64 --name usecase2_ipv6_stateles_subnet --ipv6-address-mode dhcpv6-stateful --ipv6_ra_mode dhcpv6-stateful --ip-version 6
3. boot an instance with that network

Actual results:
===============
1. Instance did not obtain IPv6 address
2. default gw is not set

Expected results:
=================
The instance should have IPv6 address a default gw configured.
