QoS of VIF not working

[Yitao Jiang]

Hi,

In CirtixResourceBase.java(
https://github.com/apache/cloudstack/blob/4.2.1/plugins/hypervisors/xen/src/com/cloud/hypervisor/xen/resource/CitrixResourceBase.java)
of createVif method , i see that the network rate value will be multiplied
by 128 .
 if (nic.getNetworkRateMbps() != null
&& nic.getNetworkRateMbps().intValue() != -1) {
 vifr.qosAlgorithmType = "ratelimit";
vifr.qosAlgorithmParams = new HashMap<String, String>();
 // convert mbs to kilobyte per second
vifr.qosAlgorithmParams.put("kbps",
 Integer.toString(nic.getNetworkRateMbps() * 128));
 }
and when i create a service_offering with 1Mb/s QoS, the vm's networking
will be limited in 128Kb/s.
All works fine.

But what i wanna do is when a service_offering with 1Mb/s then the vm will
be limited in 1Kb/s,so I change the coded like that
                            vifr.qosAlgorithmParams.put("kbps",
Integer.toString(nic.getNetworkRateMbps()));
without multiplied by 128.

But acctualy the vm still limit in 128Kb/s.

Did i miss anyting?

My environments is :
CS 4.2.1
Xenserver 6.2.0

Thanks,

Yitao
