Project Name: zuul
Type of quota increase requested: volume type, instance flavor
Amount to increase:
Reason: Many CI workloads are disk I/O bound. We need to be sure our Magnum cluster handle perform similarly to the existing integration project instances before migrating. We hope to follow the same path as T406271 enabled.

flavors: add zuul to g4.cores8.ram32.disk20.4xiops
If I'm not mistaken the above patch should gran the usage of the requested instance type. I'm not sure if there is a separate setting for the fast-iops bit or it's included in that configuration.

My understanding is that volume types are only relevant for additional volumes (created with "Volumes" in Horizon, or with the volumes API), whereas the attributes of the root volumes of instances (including the IOPS limits) are controlled by the flavor. @Andrew is that correct?
Correct. Flavor determines the performance limits for root volumes and volume type controls the limits for cinder volumes.
Yes, this project will need high iops volumes. The Magnum k8s setup uses volumes for storage on all nodes which probably makes the high iops volumes more important than the instance flavors.
