Bug description:
[Environment]
Xenial-Ocata deployment
[Description]
The instance ingress bandwidth limit implementation was targeted for
Ocata [0], but the full implementation ingress/egress was done during
the pike [1] cycle.
However, isn't reported or explicit that ingress direction isn't
supported in ocata, which causes the following exception when
--ingress is specified.
It would be desirable for this feature to be available on Ocata for being able to
set ingress/egress bandwidth limits on the ports.
[Testing]
Without these patches, trying to set a ingress bandwidth-limit rule
the following exception will be raised.
$ openstack network qos rule create --type bandwidth-limit --max-kbps 300 --max-burst-kbits 300 --ingress bw-limiter
Failed to create Network QoS rule: BadRequestException: 400: Client Error for url: https://openstack:9696/v2.0/qos/policies/xxxx/bandwidth_limit_rules, Unrecognized attribute(s) 'direction'
A single policy set (without the --ingress parameter) as supported in
Ocata will just create a limiter on the egress side.
1) Check the policy list
$ openstack network qos policy list
+--------------------------------------+------------+--------+---------+----------------------------------+
| ID | Name | Shared | Default | Project |
+--------------------------------------+------------+--------+---------+----------------------------------+
| 2c9c85e2-4b65-4146-b7bf-47895379c938 | bw-limiter | False | None | c45b1c0a681d4d9788f911e29166056d |
+--------------------------------------+------------+--------+---------+----------------------------------+
2) Check that the qoes rule is set to 300 kbps.
$ openstack network qos rule list 2c9c85e2-4b65-4146-b7bf-47895379c938
| 01eb228d-5803-4095-9e8e-f13d4312b2ef | 2c9c85e2-4b65-4146-b7bf-
47895379c938 | bandwidth_limit | 300 | 300 | | | |
3) Set the Qos policy on any port.
$ openstack port set 9a74b3c8-9ed8-4670-ad1f-932febfcf059 --qos-policy
2c9c85e2-4b65-4146-b7bf-47895379c938
$ openstack port show 9a74b3c8-9ed8-4670-ad1f-932febfcf059 | grep qos
| qos_policy_id | 2c9c85e2-4b65-4146-b7bf-47895379c938 |
4) Check that the egress traffic rules have been applied
# iperf3 -c 192.168.21.9 -t 10

5) Check that no ingress traffic limit has been applied.
# iperf3 -c 192.168.21.9 -R -t 10

6) With the patches applied from the PPA or proposed, run the
migration steps on the neutron-api node, repeat the previous steps,
but make sure to specify the traffic direction with --ingress as
follows:
$ openstack network qos rule create --type bandwidth-limit --max-kbps 300 --ingress testing-policy
+----------------+--------------------------------------+
| Field | Value |
+----------------+--------------------------------------+
| direction | ingress |
| id | 6d01cefa-0042-40cd-ae74-bcb723ca7ca4 |
| max_burst_kbps | 0 |
| max_kbps | 300 |
| name | None |
| project_id | |
+----------------+--------------------------------------+
7) Set the policy into any server port.
$ openstack port set 50b8f714-3ee4-4260-8359-820420471bdb --qos-policy
fac2be5e-64e0-4308-b477-0f8c0096c0b8
8) Check that the policy has been applied
$ openstack port show 50b8f714-3ee4-4260-8359-820420471bdb | grep qos
| qos_policy_id | fac2be5e-64e0-4308-b477-0f8c0096c0b8 |
9) Check that the rules have the "Direction field"
$ openstack network qos rule list fac2be5e-64e0-4308-b477-0f8c0096c0b8
+--------------------------------------+--------------------------------------+-----------------+----------+-----------------+----------+-----------+-----------+
| ID | QoS Policy ID | Type | Max Kbps | Max Burst Kbits | Min Kbps | DSCP mark | Direction |
+--------------------------------------+--------------------------------------+-----------------+----------+-----------------+----------+-----------+-----------+
| 6d01cefa-0042-40cd-ae74-bcb723ca7ca4 | fac2be5e-64e0-4308-b477-0f8c0096c0b8 | bandwidth_limit | 300 | 0 | | | ingress |
+--------------------------------------+--------------------------------------+-----------------+----------+-----------------+----------+-----------+-----------+
10) Validate that the hypervisor has a ovs queue and qos setup set,
max-rate should be set to 300000.
$ sudo ovs-vsctl list qos
_uuid : 2862acaa-a79f-4a62-b387-f89bca4a6965
external_ids : {id="tap75d95386-01"}

_uuid : a15774f7-ae31-40e7-9c0f-937d68a7dc0c
dscp : []
