Subject [jira] [Created] (CLOUDSTACK-6249) Modified QoS of VIF Code not working
Date Tue, 18 Mar 2014 08:13:43 GMT
Yitao Jiang created CLOUDSTACK-6249:
---------------------------------------

             Summary: Modified QoS of VIF Code not working
                 Key: CLOUDSTACK-6249
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6249
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Hypervisor Controller, Xen
    Affects Versions: 4.2.1
         Environment: CS 4.2.1 runs on CenOS 6.3
Xenserver 6.2.0

            Reporter: Yitao Jiang
             Fix For: 4.2.1


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.

After spawn a vm with 1Mb/s QoS servicing offering, through the xencenter the networking limit
still 128.
Do you guys know why , did i miss anything?
