      Goal:

      To check that the max-bw rules are applied. The scenario should be:

      • A VM (or several VMs) with port in a physical network (VLAN, flat).
      • The physical network bridge, in the compute node, should have a bond interface.
      • The QoS policy should have one single max-bw rule (egress).

       

      NOTE: it is not strictly needed to have an environment with a bond as physical network interface. Once the environment is set and the scenario defined (see upper description), it would be needed to check that the maximum bandwidth enforcement is done and there are no TC options applied on the physical interface. That would mean the maximum bandwidth enforcement is done by the OVN policer, not the HTB shaper on the interface (at it was done before the patch related to this ticket).

      NOTE: if using a single interface environment, it could be possible to check that changing the QoS policy rules change the QoS enforcement:

      • Only max-bw rules:
        • OVN QoS registers (OVN policer enforcement)
        • No LSP.options
        • No physical interface TC options
      • Max-bw and min-bw rules:
        • No OVN QoS registers.
        • LSP.options with the max and min values
        • The physical interface should have the corresponding TC qdisc and classes.
