Description RHOS Integration 2013-12-13 00:35:13 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/neutron/+spec/vif-attribute-for-hairpinning.

Description:

Currently, Nova's libvirt driver enables hairpinning on the bridge interface which breaks IPv6. We should make this a configurable setting by having Neutron send a VIF attribute that tells Nova to enable it, and the default should be to disable it, to allow IPv6 to function.

There appears to be some more background in this Nova bug: [https://bugs.launchpad.net/nova/+bug/1011134] but it's unclear how the change submitted under it in Grizzly intersects with this Icehouse blueprint
