[ovs-discuss] [ovs-dev] The QoS feature minimum guaranteed bandwidth of OpenvSwitch not work

[Xiao Ma (xima2)]

Hi, Ben & All

Just update for my testing to supply some tips.


1)I found if use the ovs bond command instead of linux bond, the qos minimum guaranteed bandwidth and max rate-limit work well.
2)Use ovs bond, must care for the rate-limits are applied to bond members parallelly and independently.
So,if bond two members, and want to make the max rate-limit to 10G,should set the max rate-limit to 10/2=5G for the bond port.

Thanks for your reply.

I configured the bond0 using linux bond then the result is not good for minimum guaranteed bandwidth.
But if I use ovs-vsctl add-bond to configure the bond0 interface, the result is good.
If I use linux bond with linux tc, the tc works well also.

 However, most problems with QoS on Linux are not bugs in Open
 vSwitch at all.  They tend to be either configuration errors
 (please see the earlier questions in this section) or issues with

Could you send  me the section link?
