Public bug reported:

Dear colleagues,

when I change port admin state to DOWN, this is not reflected
accordingly on VM's side:

$ openstack port set --disable n1-lan
$ openstack port show n1-lan
[ ... ]
+-----------------------+------------+
| Field                 | Value      |
+-----------------------+------------+
| admin_state_up        | DOWN       |
[ ... ]
+-----------------------+------------+

root@n1:~# ip a
[ ... ]
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc pfifo_fast state UP group default qlen 1000

BUT when using "virsh domif-setlink --domain <domID> --interface <MAC>
--state down" I'm getting correct "NO-CARRIER" signaling on the port:

3: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1450 qdisc pfifo_fast
state DOWN group default qlen 1000

Possibly, Nova misses messages from Neutron about port admin state
change. Is it bug or feature and can this be fixed?

My environment:

Openstack version: Pike
Host OS: Ubuntu 16.04.3
Nova: 16.0.0-0ubuntu1~cloud0
Neutron: 11.0.0-0ubuntu1~cloud0
Networking: Openvswitch 2.8.0-0ubuntu1~cloud0
Hypevisor: Libvirt+KVM
Storage: CEPH 12.2.0-0ubuntu1~cloud0

Thank you.
