Openstack Qos

Openstack network qos

1.配置QOS

此处网络为provider网络,无self-server网络,无L3
只有控制节点和计算节点
控制节点上:

vim /etc/neutron/neutron.conf
service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,neutron.services.metering.metering_plugin.MeteringPlugin,neutron.services.qos.qos_plugin.QoSPlugin

vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
extension_drivers = port_security,qos

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[agent]
extensions = qos

计算节点上:

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[agent]
extensions = qos

vim /etc/neutron/policy.json
#配置json策略文件 以下为官方文档选项,此处只选用bandwidth limit
{  "get_policy": "rule:regular_user",
	"create_policy": "rule:regular_user",
	"update_policy": "rule:regular_user",
	"delete_policy": "rule:regular_user",
	"get_rule_type": "rule:regular_user",
	
	"get_policy_bandwidth_limit_rule": "rule:regular_user",
	"create_policy_bandwidth_limit_rule": "rule:regular_user",
	"delete_policy_bandwidth_limit_rule": "rule:regular_user",
	"update_policy_bandwidth_limit_rule": "rule:regular_user",
}

重启配置服务

systemctl status neutron-server.service

2.创建策略

openstack network qos policy create 1m 
#限制速度为1m 策略名为1m
openstack network qos rule create --type bandwidth-limit --max-kbps 1000 --max-burst-kbits 1000 --egress 1m
openstack network qos rule create --type bandwidth-limit --max-kbps 20000 --max-burst-kbits 20000 --ingress 1m
#egress为出口,即上行;ingress为入口,即下行 vps qos为限制egress 其中阿里云ingress为100M
#burst-kbits突发值跟限制值一致

查看虚机端口并绑定策略

openstack port list | grep 192.168.1.245
| 15441986-a5c3-4fb5-b7ac-a76b112b9ccf |      | fa:16:3e:3b:28:a5 | ip_address='192.168.1.245', subnet_id='a60e0b12-74b6-41cd-b82b-252bb17f252d' | ACTIVE |

openstack port set --qos-policy 1m 15441986-a5c3-4fb5-b7ac-a76b112b9ccf

查看端口详情

openstack port show 15441986-a5c3-4fb5-b7ac-a76b112b9ccf

查看qos策略

openstack network qos policy list | grep fdb11583-0a68-4478-9e43-522a62bc36bf

openstack network qos rule list 1m

3.检验QOS

在虚机上安装speedtest

yum install python-pip –y
pip install speedtest-cli
pip install --upgrade pip
speedtest-cli

更换新的QOS策略

openstack network qos policy create 10m
openstack network qos rule create --type bandwidth-limit --max-kbps 10000 --max-burst-kbits 10000 --egress 10m
openstack network qos rule create --type bandwidth-limit --max-kbps 20000 --max-burst-kbits 20000 --ingress 10m
openstack port list 
#查看端口UUID
openstack port set --qos-policy 10m 15441986-a5c3-4fb5-b7ac-a76b112b9ccf 
#策略更改为10m

虚机上再次测试,策略更换成功
