starting a new instance on ephemeral storage all "quota:disk_*" setting 
are honored and work great with ceph as ephemeral backend and KVM as 
Starting a new instance with "--volume":

--volume <volume>     Create server using this volume as the boot disk 

the quota settings of the flavor are not honored. Questions:

1. Is there any way to tell nova to still honor the flavor quota 
settings if ---volume is used?

2. How to create a default volume type with an associated cinder qos to 
still have an option to prevent that volume to get unlimited iops?

Thank you so much!

All the best,
