now the stagege thing about the warining is that the tap listed is wrong.
the warning states "OVSFWTagNotFound: Cannot get tag for port tap5b6aa631-3b from its other_config: {}" however the tap should be tap472ab433-bc
so just loking at the logs around when processing of the port was skipped in the neutron agent we see
that the vms tap interface tap472ab433-bc corresponding to port 472ab433- bc18-41b5- 85ae-009611117b 70 logs.openstack. org/46/ 623246/ 3/check/ nova-multiattac h/efa830b/ logs/screen- q-agt.txt. gz#_Dec_ 11_23_56_ 12_715432
