Let us see how we can apply traffic rate limiting on an interface for designing Network QoS. The steps mentioned next will walk you through the procedure:
As a rate limiting policy is applied on the interface, find out the corresponding network interface name of the virtual machine.
virsh domiflist <vm-name>
is a handy command for this:[root@kvmHOST1 ~]# virsh domiflist Fed1 Interface Type Source Model MAC ------------------------------------------------------- fed1 bridge NewNetwork virtio 52:54:00:b3:40:
SSH to the virtual machine and check what the current ingress traffic bandwidth is. I am using the
iperf
command to determine it. There are many other utilities available such asnetperf
, check speed, and so on:[root@Fed1 ~]# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ ...
