Someone in the nova channel just reported this same bug running queens
version 17.0.4:

[20:09:16]  <sapd>      Hi everyone. I got this error when attach a SR-
IOV port to instance http://paste.openstack.org/show/726723/

Re-opening this bug as it sounds like it's still unsolved, at least as
of queens. We need to investigate it more.

  Steps to recreate:
  - Create a VM on the compute node of a multi-node deployment.
  - Attach an direct/macvtap bound SRIOV port:
     openstack server add port VM1 port1

  Results:
  - The above traceback is found in the n-cpu service on the compute node.
