Neutron QoS 使用

Neutron Liberty版已经支持openvswitch qos-rate-limiting: http://openvswitch.org/support/config-cookbooks/qos-rate-limiting/，下面我们通过简单的测试介绍其使用：

---

安装最新neutron和neutronclient

$ git clone https://github.com/openstack/neutron$ cd neutron$ sudo python setup.py install$ cd ..$ git clone https://github.com/openstack/python-neutronclient$ cd python-neutronclient$ sudo python setup.py install

打开qos plugin支持

• Neutron Server 节点
  /etc/neutron/neutron.conf, service_plugins加入qos如下：

  service_plugins = router,firewall,lbaas,vpnaas,metering,qos
  /etc/neutron/plugins/ml2/ml2_conf.ini, extension_drivers加入qos如下：
  [ml2]
  extension_drivers = port_security,qos

• Neutron Agent 节点
  /etc/neutron/plugins/ml2/ml2_conf.ini, extensions加入qos如下：

  [agent]
  extensions = qos

安全组设置

我们通过scp来测试qos，所以需要打开安全组tcp 22端口：

$ neutron security-group-rule-create –direction ingress \
–protocol tcp \
–port-range-min 22 \
–port-range-max 22 \
default

创建虚拟机

$ nova boot –image cirros-0.3.4-x86_64-uec –flavor m1.tiny –nic net-id='net-id' --min-count 2 --max-count 2 test$ nova list+--------------------------------------+--------+----------------------------------+--------+------------+-------------+-----------------+| ID                                   | Name   | Tenant ID                        | Status | Task State | Power State | Networks        |+--------------------------------------+--------+----------------------------------+--------+------------+-------------+-----------------+| 9cb84a9d-07c7-4453-a01b-ba537dcccff9 | test-1 | 68041545c58c468fa48f9bb0361e536d | ACTIVE | -          | Running     | test=172.16.1.5 || 8c8d48b6-acd8-43cc-8767-b9e7bb4afa75 | test-2 | 68041545c58c468fa48f9bb0361e536d | ACTIVE | -          | Running     | test=172.16.1.6 |+--------------------------------------+--------+----------------------------------+--------+------------+-------------+-----------------+

创建QoS规则

$ neutron qos-policy-create --shared test-policyCreated a new policy:+-------------+--------------------------------------+| Field       | Value                                |+-------------+--------------------------------------+| description |                                      || id          | 8c399fce-4398-4151-b29f-17d7e55c1670 || name        | test-policy                          || rules       |                                      || shared      | True                                 || tenant_id   | 037efa515b1e44c682fff1a337371962     |+-------------+--------------------------------------+$ neutron qos-bandwidth-limit-rule-create --max-kbps 1000 --max-burst-kbps 100 test-policyCreated a new bandwidth_limit_rule:+----------------+--------------------------------------+| Field          | Value                                |+----------------+--------------------------------------+| id             | ad919837-e4d8-4601-b512-e4b3dd1ee655 || max_burst_kbps | 100                                  || max_kbps       | 1000                                 |+----------------+--------------------------------------+

添加QoS规则至端口
