Hi Naveen, <div><br></div><div>I see what's going on. This is actually a bug that was fixed here: <a href="https://github.com/openstack/quantum/commit/e702264e310714a2369713fad95264d3ccedb66b" target="_blank">https://github.com/openstack/quantum/commit/e702264e310714a2369713fad95264d3ccedb66b</a></div>
<div><br></div><div>As a work around you can run: </div><div><br></div><div>ovs-vsctl list-ports br-int </div><div>and then delete all of the non-existing ports via: </div><div>ovs-vsctl del-port br-int <xxxx></div>
<div><br></div><div>The issue was that when you rebooted ports attached to br-int were not properly removed.</div><div><br></div><div>Aaron</div><div><div><br><div class="gmail_quote">
