So, that is normal operation, actually. The conductor calls the scheduler to find a place for your requested instances. The scheduler responded to the conductor that, sorry, there were no hosts that were able to match the request (I don't know what the details of that request were). And so

Hi Jay, Thank you for getting back. I attached the log in my previous reply, but I guess Gmail hided it from you as a quoted message. Here comes again: From nova-conductor.log ### BEGIN ### 2018-08-08 09:28:35.974 1648 ERROR nova.conductor.manager [req-ef0d8ea1-e801-483e-b913-9148a6ac5d90

I would think you don't even reach the scheduling stage. Why bother looking for a suitable compute node if you exceeded your quota anyway? The message is in the conductor log because it's the conductor that does most of the work. The others are just slackers (like nova-api) or wait for

Hi Jay, Thank you for getting back to my question. I agree that it is not an error; only a preset limit is reached. I just wonder why this incident only got recorded in the nova-conductor.log, but not in other files such as nova-scheduler.log, which would make more sense to me. :-) By the way,

Hi everyone, I intentionally triggered an error by launching more instances than it is allowed by the 'cpu_allocation_ratio' set on a compute node. When it comes to logs, the only place contained a clue to explain the launch failure was in the nova-conductor.log on a controller node. Why there is
