Hi Rodolfo, was that, thank you very much !! Regards Felipe On Mon, Jul 19, 2021 at 9:32 AM Rodolfo Alonso Hernandez < ralonsoh@redhat.com> wrote:
Hello Felipe:
Did you configure both the server and the agent? Probably you configured the server correctly, this is why you can create and apply the QoS policies.
But you also need to configure the OVS agent [1]. In the plugin ML2 config (by default /etc/neutron/plugins/ml2/ml2_conf.ini), you need to configure the agent extension:
[agent]extensions = qos
Check this config file and then enable the OVS agent debug logs (restarting the agent). Check the logs for any QoS message there. You should also check: - For BW limit ingress rules (ingress from the VM point of view, this is the default point of view): the OVS agent creates a QoS register and a queue register in the OVS DB table. You should see them using ovs-vsctl tool. - For BW limit egress: the OVS agent modifies the port Interface table, setting the "ingress_policing_rate" and "ingress_policing_burst" (we don't do traffic shaping, we drop packets exceeding the max rate but it works).
I hope that helps you to debug what is happening there.
Regards.

Hi,
I am using OVS as backend.
I can set networking limit by QoS and openstack accepts and can check QoS settings (bandwith, etc..) but nothing matters, I always get maximun transfer speed.

Felipe

Hello Felipe:
What network backend are you using? OVS, SR-IOV, OVN or Linux Bridge? Or any other out-of-tree backend?
Regards.

Hi,
I am running openstack victoria installed using packstack.
Everything things to be fine except bandwidth limit. I have tried to limit internal traffic between two instances and between instances and "Internet" but I always get maximum data transfer speed.
I have set up following rules
openstack network qos rule create --type bandwidth-limit --max-kbps 3 --max-burst-kbits 2 --ingress bw-choke openstack network qos rule create --type bandwidth-limit --max-kbps 3 --max-burst-kbits 2 --egress bw-choke
and applied bw-choke policy to the internal network where my instances are deployed:
openstack network set --qos-policy bw-choke newdeploylab_private_network
and to ports where machines connect to subnet:
openstack port set --qos-policy bw-choke 503a07b8-2da0-4abe-8251-ede648ba42b4 openstack port set --qos-policy bw-choke 776d5fb3-639c-47cc-9b0f-6ec855397df7
but nothing happens.
Each time I try to download something from internet or copy data from an instance to another I always get maximum data transfer speed.
I have followed instructions from https://docs.openstack.org/neutron/victoria/admin/config-qos.html
Any ideas?
