Nova Outbound average bandwidth not working on Ubuntu with KVM

asked 2015-06-17 20:26:20 -0600

Not sure if this is the correct place to ask this question, but was wondering if anybody has run into this before and had any advise.

I am trying to test Network QOS on Nova, it uses tc under libvirt, The outbound average is not working, i see inbound average works fine. If i set outbound peak value with outbound average value it works fine , but if only the outbound average is used it doesn't work. I ran tc disc, class, filter show command on tap interfaces on two different vms one that had only the outbound average and one that had both average and peak.. i did not notice any difference in the output for the two. Which makes me really curious as to how outbound peak cap even work ?

Any insights into how to get outbound average to work, would be appreciated. Also if I could understand how the outbound peak works would be really helpful.
