Hi Kim<br><br>I just did the same switching from gre to vxlan.<br>Here's what I learned:<br><br>You have to delete all the old networks in the installation that where<br>created with gre. They do not work because the tunnel type is stored in<br>
the DB. I was not able to change it.<br><br>According to ovs-neutron_plugin.ini. I think this depends on the<br>distribution used. I realized, that not all daemons read the same config<br>files on startup. Thats why I had also to modify both mentioned files.<br>
To ensure all parameteters are set, I used debug=True and verbose=True<br>like this you see the configuration the daemon uses in the logfile.<br><br>hope this helps<br><br>Benedikt<br><br><br>On 28.05.2014 04:32, BYEONG-GI KIM wrote:<br>

the guide describes<br>/etc/neutron/plugins/openvswitch/ovs-neutron_plugin.ini also needs to be<br>modified. But I didn't because the Installation Guide for OpenStack<br>Icehouse didn't mention such things even though the guides shows how to<br>
