I deleted both DHCP ports and they recreated as you said. However, instances are still unable to get network addresses automatically. Torin Woltjer Grand Dial Communications - A ZK Tech Inc.

The door is recreated automatically. The problem like I said is not in DHCP, but for some reason, erasing and waiting for OpenStack to re-create the port often solves the problem. Please, if you can find out the problem in fact, let me know. I'm very interested to know. You can delete the door without fear. OpenStack will recreate in a short time. -------------- next part -------------- An HTML attachment was scrubbed...
