<div>
<p class="MsoNormal">Hey folks,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<div>
<p class="MsoNormal">I was using vanilla openvswitch plugin and upgraded to ML2 recently. My existing networks work fine, but new networks are causing me troubles.<o:p></o:p></p>
</div>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">It seems that a new network defaults provider:network_type to "local". Since I am running openvswitch agents with network_type set to VXLAN only everywhere, all ports are down in this setup.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So, I tried to create a network and specify provider:network_type to vxlan (which is the case for my existing networks). This time, the network cannot be created at all, got an error of NoNetworkAvailable: Unable to create the network.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Any ideas?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Thanks.<o:p></o:p></p>
