Hi Rushikesh, Iâve made a mistake â this fix did get into XCP 1.6.10. It didnât make it into version 6.1 of commercial XenServer, which is what confused me.


The original problem could still be caused by kilobit/kilobyte confusion, as George suggests.

Hello John,

Since the commit is 4 months old can we consider that it is fixed in XCP1.6.10 or are you suggesting that the current stable XCP1.6.10 has this known bug ? ( I assumed 2nd but just want to confirm )

By looking at patch, it looks safe to locally integrate into XCP1.6.10 xapi.src.rpm. Any suggestions ?

Thereâs also a known bug in XCP 1.6, where the API QoS settings donât actually get passed down to Xen. The master branch patch is here: https://github.com/xen-org/xen-api/commit/4fb4b96b10c2d40cd5e166845659f27882c6dae5

Hey everyone,


I'm currently testing and documenting the qos parameters for VIF interfaces. I've set up two VMs with VIF interfaces attached to an internal network. I've set the following qos parameters on each VIF interface.


xe vif-param-set uuid=<VIF UUID> qos_algorithm_type=ratelimit

xe vif-param-set uuid=<VIF UUID> qos_algorithm_params:kbps=100


iperf is showing me bandwidth rates between the two VMS that aren't limited to 100 kbps. Am I missing something? 


kbps is not kbps, but a KiloBYTESperSecond. Really strange, but it is. kbps=12 will make it 100kpbs.
