[Bug 1279751] [NEW] Disallow create port if network is not shared and port/net tenant_id doesn't match

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Admin user is able to create port whose tenant is different from the
owner network even the network is not shared. It isn't intended.

The port is usable, but if trying to detach the port from an instance,
the following exception occurred:
