> 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
