Dear all,

Is it possible to use the same physical NIC with the SR-IOV mechanism driver together with other mechanism driver like Open vSwitch or Linux Bridge? If this is the case, how should I map the physical NIC for each agent?

yes you have to use fdb extention which is support by ml2/ovs and ml2/linuxbridge https://github.com/openstack/neutron/blob/master/neutron/agent/l2/extensions...

but with that you can use the PF for ovs and the vf for vms. im not sure if there are other docs https://docs.openstack.org/neutron/rocky/admin/config-sriov.html#optional-fd... but that is a start

I only known how to map the NIC separately for each driver; for example:

• for the Linux bridge agent: physnet1: eth3,
• for the OvS agent: physnet1: br-provider

(eth3 is a port of br-provider)

• for the SR-IOV agent: physnet1: eth3

Any guide or sample reference about implementing multiple mechanism drivers would be highly appreciated.

Thanks in advance, Gabriel Gamero
