I'm having the same problem when trying to migrate from OVS to ML2<br>
<br>
Here's /var/log/neutron/server.log<br>

<div>This email supersedes my previous one on 2014/04/20 20:24
UTC,</div>
<div>which wasn't properly formatted.</div>
<div><br>
</div>
<div>I decided to upgrade my Havana deployment to Icehouse right
after the</div>
<div>official release so I could contribute on the documentation
with the</div>
<div>steps necessary, including Neutron and going from the OVS
to the ML2</div>
<div>neutron plugin.</div>
<div><br>
</div>
<div>However, I'm still having problems due to the ML2
migration.</div>
<div><br>
</div>
<div>All nodes (1 hybrid Controller/Network and 1 Compute) are
running up</div>
<div>to date Ubuntu 12.04.4 LTS.</div>
<div>Havana was working perfectly before (OVS with GRE).</div>
<div><br>
</div>
<div>------------------------------------------------------------------</div>
<div>Most important steps done so far:</div>
<div><br>
</div>
<div>- Updated everything to Icehouse;</div>
<div><br>
</div>
<div>- Ran all database migration commands (typical db
sync/db_sync);</div>
<div><br>
</div>
<div>- Ran Neutron's own migration commands, in the following
ways:</div>
<div> neutron-db-manage --config-file
/etc/neutron/neutron.conf \</div>
<div> --config-file
(...)/ovs_neutron_plugin.ini \</div>
<div> stamp havana</div>
<div> neutron-db-manage --config-file
/etc/neutron/neutron.conf \</div>
<div> --config-file
(...)/ovs_neutron_plugin.ini \</div>
<div> upgrade icehouse</div>
<div><br>
</div>
<div>- Manually ran the ML2 migration script:</div>
<div> python -m neutron.db.migration.migrate_to_ml2
openvswitch \</div>
<div> mysql://neutron:mypass@mycontroller/neutron</div>
<div>------------------------------------------------------------------</div>
<div><br>
</div>
<div>Here are the contents of the ml2_port_bindings table,</div>
<div>right after I run the ML2 migration script:</div>
<div><a moz-do-not-send="true"
href="http://paste.openstack.org/show/76513/">http://paste.openstack.org/show/76513/</a></div>
<div><br>
</div>
<div><br>
</div>
<div>But, if I restart the neutron services, it becomes:</div>
<div><a moz-do-not-send="true"
href="http://paste.openstack.org/show/76515/">http://paste.openstack.org/show/76515/</a></div>
<div><br>
</div>
<div><br>
</div>
<div>Either way, starting nova-compute service at the Compute
node yields:</div>
<div>(...)</div>
<div>vif_type parameter must be present for this vif_driver
implementation</div>
<div>(...)</div>
<div><br>
</div>
<div>And doesn't start.</div>
<div><br>
</div>
<div>Any ideas?</div>
<div><br>
</div>
<div>Best regards,</div>
<div>
