<p class="MsoPlainText">Thanks for your response. I read the blog and my requirement is shared IB network as of now. We have developed a Neutron ML2 driver that manages the IB subnet[1].<o:p></o:p></p>
<p class="MsoPlainText">Regardless of that, I think my current issue is because the cloud-init is not able to recognize the port as IB port. How did it work for you? You can see my ironic port details.<o:p></o:p></p>
