Comment 3 Kevin Traynor 2023-06-16 09:14:39 UTC

Please check if this is still the case with OVS 2.17 or 3.1 ?

If so, 
Is this occurring with other NICs on this DUT ?

When were these tests last stable and what components have changed since then ?

What are the commands used?

Comment 4 liting 2023-07-07 01:45:27 UTC

I will check if this issue still with ovs2.17 and 3.1. When I run job on rhel9.2, the trex port will down after the connect port bound to vfio-pci. I have open another bug.https://bugzilla.redhat.com/show_bug.cgi?id=2220900
