Hi:
I created a port,attached the interface to a VM,and then detached the interface from the VM.I found that the port was deleted.
I think the port should not be deleted when the interface is detched,if the port is created independently.
Thank you.
Currently there is no distinction between a port created explicitly by a user or admin and a port created by the infrastructure (in this case Nova), so all ports are equal and disposed of when the resource that is using it is destroyed (in this case a VM).
I think it is fair to create a bug report and mark the bug as wishlist or opinion to see what people think about this particular issue.
I would also post this in the quantum quantum section.
I view the codes.
In the method nova.compute.manager.ComputeManager.detach_interface(),the method nova.network.quantumv2.api.API.deallocate_port_for_instance() is called where the port is deleted.
def deallocate_port_for_instance(self, context, instance, port_id, conductor_api=None): try: quantumv2.get_client(context).delete_port(port_id) except Exception as ex: LOG.exception(_("Failed to delete quantum port %(port_id)s ") % locals())
This may be the problem.
I believe the bug reports above are somewhat related to the issue we are seeing here, i.e. the port gets deleted when the VM is destroyed.
