删除QOS并清除网卡QOS​

libvirtd 限速接口​

Libvirtd默认提供domiftune限制网卡流量

查看虚机接口的限速设置​

virsh  domiftune 4ffbd71f-3324-4500-8636-f9a275b6e479 tap53eeb988

设置虚机接口限速​

$ virsh domiftune 4ffbd71f-3324-4500-8636-f9a275b6e479 tap53eeb988 --inbound 700000,800000,800000 --outbount 700000,800000,800000 --live

单位如下：

average bandwidth   kilobytes/second 
peak bandwidth      kilobytes/second 
burst size          kilobytes

这里要注意的是domiftune只针对网络模式为nat，route等方式，对模型为bridge, passthrough, private,和hostdev是不支持限制的。
