<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">We debugged it in IRC. You can see errors in trying to add tap port in the dhcp log [search for br-int]. I am not sure if this is same log that he shared with
me, but the problem was that br-int wasn’t created by the time q-dhcp tried adding it. That is why I recommended trying out with Liberty coz “Wait for br-int” was added post kilo.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Things worked out for him in a new fresh VM. He had installed latest version of OVS in this failing setup. So, I’m suspecting it could be a case of two different
instances of OVS [installed in different locations] running with devstack code using one while q-dhcp code using other. I believe q-dhcp picks it off entry-point configuration while devstack picks off PATH variable.

<p class="MsoNormal">what happens if you do ip netns? Do you see the qdhcp-xxx namespaces? And then can you do a ip netns exec qdhcp-xxx ip link and see any tap ports?<u></u><u></u></p>

<div>
<p class="MsoNormal">A high-level set of actions that happens with dhcp is as follows. I don't think I have the ordering right, but these are the actions that happens eventually.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>

</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">I also listed some debug commands you can use. The log you have assumes that the tap port was there. I don't see any output trying to actually add the port. So I would work from that log looking at the qdhcp name space and the port. See
where it broke.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">It's also possible you have some left over junk somewhere. Maybe that dhcp name space or port do not exist and are stale. Stacking and restacking without cleaning the ovsdb in between runs isn't good. Also moving from one release to another
can lead to problems. Go forward isn't as bad as going backwards, but still it normally leads to trouble.<u></u><u></u></p>
