<div>Hi,</div>
<div> </div>
<div>We want somehow to add a new interface to a running VM. To modify an existing interface (by assigning it to a new subnet) could be also an alternative.</div>
<div>We tried the following:</div>
<div> </div>
<div>Quantum port-update <port-id> --device_id <new VM id></div>
<div>This worked but required nova rebuild command.</div>
<div> </div>
<div>Quantum port-update <port-id> --fixed_ip ip_address=x.x.x.x</div>
<div>This command was executed successfully but did not have any effect.</div>
<div> </div>
<div> </div>
<div>Do you have any suggestions what we could try next or is this currently something that is not possible to do?</div>
<div> </div>
<div>BR</div>
