<div>Hi Nicolas,<br>
<br>
You need another interface ( say eth1 UP & running ) . Configure br100 to use eth1 .<br>
<br>
<br>
<br>
typically your configuration will look like the below ..<br>
<br>
<br>

<div>Hi stackers,<br>
<br>
I got, using devstack, openstack running. I can launch instance correctly (as seen in horizon state) but the instance can't reach the dhcp or the metadata.<br>
<br>
Here the topology (as it <i>should</i> be, but I maybe need to configured otherwise in the conf) of my server (one box only) :<br>
<ul>
<li>router : 192.168.23.1</li><li>server <br>
<ul>
<li>ip : 192.168.23.5 (with dhcp but always the same)<br>
</li><li>interface with external (network and internet) : eth0</li><li>interface for openvswitch bridge : br100</li><li>interface for nova/quantum/melange bridge : br100</li></ul>
</li><li>openstack
<ul>
<li>glance with file backend </li><li>quantum and melange for networking</li><li>openvswitch as plugin<br>
</li></ul>
</li></ul>
<p>You can find all the config files and log here : <a href="https://gist.github.com/2342747" target="_blank">
https://gist.github.com/2342747</a>.<br>
And networking info below.</p>
<p>Any tips, or pointing misconfiguration will be very appreciated.<br>
