<p dir="ltr">It will reflect poorly on the Neutron project because we are defaulting to something that gets almost no development effort and that is not even gated on (other than unit tests). This is a risky move that can damage first-time users' opinions of the viability of OpenStack. I wouldn't feel confident about something that has defaults that could be broken at any time... even during a release. </p></blockquote><div><br><div class="gmail_default" style="font-family:courier new,monospace;display:inline">Well, this is part of the motivation behind this patch.

<p dir="ltr">Can someone point me to the list of complaints about OVS? I would rather invest time in addressing those issues rather than ignoring everything a good chunk of the neutron community has spent significant time on. </p>
<p dir="ltr">If OVS really is a non-starter because of lack of tooling and lack of deployer experience, we (the neutron community) will need to put significantly more efforts into automated testing and feature parity (e.g. re-implement DVR). </p></blockquote><div><div class="gmail_default" style="font-family:courier new,monospace;display:inline">The idea is to make the entry level for using neutron networking as low as possible.
