Hi, To follow up on the complications of bringing up trunk subports [1] I have written up a small proposal for a tiny new feature affecting neutron and nova. That is how to expose trunk details over metadata API. To avoid big process overhead I have opened a newton rfe ticket [2], plus a nova specless blueprint [3] pointing to it. Please let me know if I should have followed a different process. Cheers, Bence [1] http://lists.openstack.org/pipermail/openstack-dev/2016-September/104848.html [2] https://bugs.launchpad.net/neutron/+bug/1631371 [3] https://blueprints.launchpad.net/nova/+spec/trunk-details-meta
