[Bug 1647408] [NEW] Neutron port update with device id does not work with nova properly

 

Public bug reported:

Deploy a new VM (VM1) and attach a network interface to it. Deploy
another VM (VM2). Using Neutron port update API, update device id (to
nova instance of VM2) of network interface attached to VM1. In neutron,
device id gets updated successfully. However, the changes are not
reflected in nova. For example, VIF unplug of port from VM1 is not
called (and subsequently VIF plug of port to VM2 is not called).

Neutron port update with device id does not work with the networking of
nova and neutron. With current code, Neutron api allows device id of a
port to be updatable, however, it does not get carried over to nova
appropriately.
