Thank you, Bernd. I didn't know the inner workflow in this case. Initially, I thought it was for the scheduler to discover that no more resource was left available, hence I expected to see something from the scheduler log. My understanding now is that the quota get checked in the database prior to the deployment. That would explain why the clue was in the nova-conductor.log, not the nova-scheduler.log.

I am attaching it below for the record. Hope the format won't get too messy... From the nova-conductor.log ### BEGIN ### 2018-08-08 09:28:35.974 1648 ERROR nova.conductor.manager [req-ef0d8ea1-e801-483e-b913-9148a6ac5d90 2499343cbc7a4ca5a7f14c43f9d9c229 3850596606b7459d8802a72516991a19 - default default] Failed to schedule instances: NoValidHost_Remote: No valid host was found.
