Whenever I try to attach a direct port to an existing instance It fails:

[Gary Kotton (garyk)]

This looks like a nova issue and not a neutron one.

[Moshe Levi (moshele)]

we are working on adding Attach/detach SR-IOV interface in nova https://review.openstack.org/#/c/139910/.
as gray said it is not related to neutron

[Sivasathurappan Radhakrishnan (siva-radhakrishnan)]

lvmxh Can you please let me know if you are still working on this wishlist

[Anusha Unnam (anusha-unnam)]

@lvmxh If you wish to work on this bug, please reassign yourself.

[Matt Riedemann (mriedem)]

See: https://docs.openstack.org/nova/latest/contributor/project-scope.html#api-scope

You can create a port and then attach it to the server, so if you need a more advanced type of port, do it that way so the compute API doesn't have to orchestrate that for you.
