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
