Public bug reported: Related Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2093739
For minimum bandwidth, the OVS agent is create a QoS policy assigned to the physical bridge interface. Any new port with a min-bw QoS rule will create a queue attached to this QoS policy. OVS creates the corresponding "tc" linux-htb policy in the interface, creating a root class. Each new queue will be represented as a new child class on top of the parent one (that represents the QoS policy). The problem we have, as commented in [1], is that we are not providing any "ceil" value (max-rate) in the parent class or the child ones. If no "ceil" value is provided, 100Mbits/s will be assigned. Any child class with a higher "rate" (min-rate) than "ceil" won't be able to set this value.
