Hi, Ricado, I’m sure that HTB can work well in OVS. Could you please paste your HTB parameters and flow configurations? Then I might know what is the problem.
And another question, how long is your queues (queue size) of HTB? Thanks.

Each flow from the first group has a low bandwidth requirement and should be prioritized over the traffic from the second group flows. Each flow from the second group needs a higher amount of bandwidth. So far my configuration consists in creating a HTB QoS entry in each used node with OVS for all the ports used to route the traffic. Then I create 2 queues, one for each group of traffic and add flow rules with the appropriate enqueue options. In order to prioritize the traffic from one queue to another, I'm configuring the queues with the "priority" option, having the first group queue with priority 1 and the second with priority 2. However, I still experience packet loss in flows from the first group with this setup (the required bandwidth from these flows is short). Do you maybe know what's causing it? Shouldn't this configuration theoretically work? I was playing with the available HTB options in Open vSwitch and so far the only way to avoid packet loss in group 1 flows was to create a max-rate value in the other queue, limiting the available bandwidth, but I want to avoid limiting the queues' bandwidth, only prioritize the respective traffic. I am using Open vSwitch 2.3.0 with Ubuntu Server 14.04.1. Any help is appreciated. Thank you.
