Dear OVS community,
I am trying to setup OVS offload on a mellanox connectX4-LX through 2 vms suing
SR-IOV to the VFs.
For some reason when I start pinging the offload works but after a while I am
getting this error message:
[root@zeus-54 ~]# systemctl status openvswitch

This is an example when I ping between 2 vms on same host:

I am not an expert on these topics so apologize beforehand for the lack of
information provided (I skipped the OVS/kvm configuration for the sake of
simplicity but happy to put it here is needed)
Could someone please advise what “Mar 22 16:11:06 zeus-54.localdomain
ovs-vswitchd[36214]: ovs|00001|dpif_netlink(handler60)|ERR|failed to offload
flow: Invalid argument: ens2f0_0” means?
Thank you very much
Manuel
