<body class='hmmessage'><div dir='ltr'>Hi,<BR><br><BR>I had the same problem. I found a solution in RDO Openstack forum.<BR>link: http://openstack.redhat.com/forum/discussion/comment/561#Comment_561<br><BR>1) stop quantum services and remove ports from ovs.<BR>
<pre><code># ovs-vsctl del-port br-int xxxxx
# ovs-vsctl del-port br-ext xxxxx
</code></pre>
It's cleaned up as:<BR>
<pre><code># ovs-vsctl show
394e8a6b-a5e0-4fef-8f8f-506889aebfc1
Bridge br-int
Port br-int
Interface br-int
type: internal
Bridge br-ex
Port br-ex
Interface br-ex
type: internal
Port "eth0"
Interface "eth0"
ovs_version: "1.10.0"
</code></pre>
2) add ovs_use_veth = True in l3_agent.ini, dhcp_agent.ini and lbaas_agent.ini.<BR><br><br><div><hr id="stopSpelling">Date: Thu, 11 Jul 2013 10:50:23 +0800<br>From: jt628910@163.com<br>To: openstack@lists.launchpad.net<br>Subject: [Openstack] VM do not get ip when use quantum<br><br>
