<p class="MsoPlainText">That DOWN status output from ovs-vsctl show is confusing, perhaps it meant to say that the interface is sort of "on demand" consumption that if there is a traffic it will be on. What you can do is to session into the dhcp namespace and
run tcpdump on that interface there. Here are the steps,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">1. sudo ip netns exec <your qdhcp namespace> bash<o:p></o:p></p>
<p class="MsoPlainText">2. sudo tcpdump -n -e -vv -i <your dhcp server tap interface><o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Then on your controller node, create a new VM, you should see some packets dump on your dhcp namespace, similar to this,<o:p></o:p></p>
