Hi, We currently have a bug for IPv6 work, which is to disable hairpinning on the bridge that Nova creates. By default, it is always turned on, which prevents instances from configuring IPv6 SLAAC addresses https://launchpad.net/bugs/1251235 https://review.openstack.org/#/c/56381/ Daniel Berrange has suggested that it be a per-VIF attribute - and in principle I agree - provided that the default is to not enable hairpinning. I would appreciate anyone's thoughts in the matter. -- Sean M. Collins
