Description Eduard Barrera 2018-11-25 09:51:51 UTC

Description of problem:


Customer did want to add an additional network to an already compute node. They want to add an external network to the node in order to sync with NTP.
The attempt failed with the following with

Customer did revert back the change but still experiencing a very similar issue:
