<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">No, the complaints from ops I have heard even internally, which I think is being echo'd here is "I understand how linux bridge works, I don't opensvswitch". and "I don't want to
be bothered to learn to debug openvswitch because I don't think we need it".<br>
<br>
If linux bridge had feature parity with openvswitch, then it would be a reasonable argument or if the users truly didn't need the extra features provided by openvswitch/naas. I still assert though, that linux bridge won't get feature parity with openvswitch
and the extra features are actually critical to users (DVR/NaaS), so its worth switching to opevnswitch and learning how to debug it. Linux Bridge is a nonsolution at this point. :/ So is keeping nova-network around forever. :/ But other then requiring some
more training for ops folks, I think Neutron can suit the rest of the use cases these days nova-network provided over neutron. The sooner we can put the nova-network issue to bed, the better off the ecosystem will be. It will take a couple of years for the
ecosystem to settle out to deprecating it, since a lot of clouds take years to upgrade and finally put the issue to bed. Lets do that sooner rather then later so a couple of years from now, we're done. :/<br>

<div dir="ltr">I definitely understand that. But what is the major complaint from operators? I understood that quote to imply it was around Neutron's model of self-service networking.
<div><br>
</div>
<div>If the main reason the remaining Nova-net operators don't want to use Neutron is due to the fact that they don't want to deal with the Neutron API, swapping some implementation defaults isn't really going to get us anywhere on that front.</div>
<div><br>
</div>
<div>It's an important distinction because it determines what actionable items we can take (e.g. what Salvatore mentioned in his email about defaults). Does that make sense?</div>

<br>
</span>And conversely, swapping simple bridge interfaces for something else<br>
still means problems are harder to debug, whether or not you're<br>
stuck with self-service networking features you're not using.<br>
