Comment 4 Rodolfo Alonso 2023-05-22 15:41:56 UTC

Hello:

1) I don't know exactly when OSP dropped support for MacVTap (if we ever supported it). It is a bit hidden in the docs [1], but "vnic_type=macvtap" is not supported since OSP10. We should then remove this reference from [2]. The text there is a direct copy/paste from the Neutron configuration option description [3], this is why is present there.

2) This component will be generated because this is a Neutron agent, same as ML2/Linux Bridge [4]. The presence of this code doesn't mean we support it. We generate the component I guess because is more difficult to create exception rules to stop building these RPMs.

Regards.

Comment 5 Greg Rakauskas 2023-05-26 16:55:05 UTC

Hi,

Responding to Comment 4, item 1:

   - Starting in RHOSP 12, the "Networking Guide" ([1] above) no longer mentions
     macvtap.

   - The RHOSP Docs team is in the process of removing macvtap from the RHOSP 
     "Configuration Reference" ([2] above) for the active RHOSP releases: 16.1,
     16.2, and 17.0. Work for this is being tracked in BZ 2209121.

Thanks,
--Greg
