Hi,
I used devstack to deploy Juno OpenStack.
By default, devstack created 2 users: admin (with role “admin”) and demo;
and 2 networks: public (tenant = admin) and private (tenant = demo)
In CLI as user demo, there is one port created (attached to the Neutron router):
localadmin@qa4:~/devstack$ source openrc demo demo
localadmin@qa4:~/devstack$
localadmin@qa4:~/devstack$ neutron port-list

Note that port with fixed IP 10.0.0.2 is created for the VM.
However, an additional port with fixed IP 10.0.0.3 is also created.

This port remains after deleting the VM.

Request to delete server vm1 has been accepted.

Now create another VM. Note that there is only one new port created; no
additional port is created as before during the first VM creation.

Is this expected behavior?
