---------------------------------------
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?
