RE: [nova] failing OVS offload on mellanox connectx-4 (RepresentorNotFound: Failed getting representor port for PF ens2f1 with 7)

5 Mar 2019

      You're in legacy mode for OVS offload you need switchdev mode
[root@zeus-54 ~]# devlink dev eswitch show pci/0000:88:00.0
pci/0000:88:00.0: mode legacy inline-mode none encap enable

You should run this [1] command to set it for switchdev mode
sudo devlink dev eswitch set pci/0000:88:00.0 mode switchdev

Please see [1]

Subject: [nova] failing OVS offload on mellanox connectx-4 (RepresentorNotFound: Failed getting representor port for PF ens2f1 with 7)

Dear Openstack community,

first let me apologise for my ignorance in this topic, this is the first time I try to setup an environment like this and I don't know anyone who has done it before.

I am trying to setup OVS offload following this document https://docs.openstack.org/neutron/rocky/admin/config-ovs-offload.html

My Openstack is Rocky deployed through kolla-ansible.

I have a feeling my OVS offload is not setup properly as vm creation fails and the error "RepresentorNotFound: Failed getting representor port for PF" can be see in nova-compute logs.

Am I supposed to see the PFs attached to a port in the ovs-dpctl show output?
What else can I check?

Thank you very much
