Re: [Xen-API] qos_algorithm_type=ratelimit

Hi Matthew,

After setting those parameters, you probably need to re-plug the VIFs (unplug + plug), or reboot the VMs, for the setting to take effect. You can check if the "rate" key in xenstore is set (xenstore-ls -f | grep rate) to confirm.

Cheers,

Rob

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?
