Hi

I am using 0.9.4 version of libvirt and want to limit bandwidth.
I installed libvirt on ubuntu 11.04 using libvirt source.

For this i am using the QOS configuration

<devices>
<interface type='network'>
<source network='default'/>
<target dev='vnet0'/>
<bandwidth>
<inbound average='1000' peak='5000' burst='1024'/>
<outbound average='128' peak='256' burst='256'/>
</bandwidth>

</interface>

Here the inbound limit is working properly but the outbound is limiting but not with values which is give

Here are the scenarios i tested and the results

when i gave average as 2048 --- it is limiting with 600 -- 700 kb

average                           result
=====================
2048   (2mpbs)                  600-700 kb
4096   (4mbps)                  1 MB/s
10240 (10mbps)                2-3 MB/s
12288 (12 mbps)               3-4 MB/s
20480 (20 mbps)               16-18 MB/s

Is this the expected behavior or some thing is missing
If this is the expected behavior ,then in what ratio it is limiting.

Please help me
Thanks in advance.
