Hi
I have configured a provider flat network with ipv6 subnet in ra mode slaac and address mode slaac. However, when i launched a ubuntu trusty VM, it couldn't get the ipv6 address but ipv4 only. I am running the trunk code BTW. The command used are:

neutron net-create --provider:network_type=flat --provider:physical_network=datacentre --router:external=true provider-net neutron subnet-create --ip-version=6 --name=ipv6 --ipv6-address-mode=slaac --ipv6-ra-mode=slaac provider-net 2001:470:1f0e:cb4::0/64 --allocation-pool start=2001:470:1f0e:cb4::20,end=2001:470:1f0e:cb4::fffe --gateway 2001:470:1f0e:cb4::3 neutron subnet-create --ip-version=4 --name=ipv4 provider-net 162.3.122.0/24 --allocation-pool start=162.3.122.4,end=162.3.122.253
neutron router-interface-add default-router ipv6
neutron router-interface-add default-router ipv4

The vm is reachable when i configured the ipv6 address calculated by neutron manually on the nic.
How can i get the auto configuration to work on the VM?
Thanks!
