[jira] [Commented] (CLOUDSTACK-2820) Global parameter
"network.throttling.rate" is not controlling data transfer rate
[ https://issues.apache.org/jira/browse/CLOUDSTACK-2820?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13673083#comment-13673083 ]
Wei Zhou commented on CLOUDSTACK-2820:
--------------------------------------
Hi,
I do not know how you set transfer rate on VR interface, so I do not know whether it is a Xenserver issue.
AFAK, KVM supports setting parameters of network interfaces on a running VMs.
However, CloudStack only changes the XML definition of the VMs.
So you need to restart cloudstack-management server, and stop/start (not reboot) the virtual router or restart network to take changes into effective.

> Virtual router's interfaces are getting QOS based on GP "network.throttling.rate" value but in actual there is no control on data transfer rate.
> Steps to rep
> -------------------
> 1-Set GP "network.throttling.rate" to some value say 3 Mb/s;restart MS
> 2-down load a file in VR
> 3-copy file from vm to some location using rsunc/scp
> expected
> -------------
> Transfer rate should not be more that 3Mb/s
> Actual
> ---------
> i see transfer rate 15.50 MB/sec
> My observation
> ---------------------
> I manually set transfer rate to 100KB/s on VR interface ,saw same issue.Looks like Xenserver issue
