Hi,<br><br>I think the best way is to delete the instance from the database :<br>Look at the "nova" database and "fixed_ips" table.<br><br>If you have the old instance number here, try put the "instance_id" filed into NULL where instance_id is 603.<br>
<br>If you have still this issue, find every field corresponding to 603 into the database and delete it.<br><br>Restart nova-api service, and that should be good.<br><br><br>Good luck !<br><br><br>Regards<br><br><div class="gmail_quote">
