Hi,
I'm going to remove Cinder from this bug. If this is wrong, please let me know why Cinder should be added to this bug. 
Thanks!

Title:
  size_iops_sec does behave different than mentioned in docs

Status in OpenStack Compute (nova):
  Incomplete

Bug description:
  In documentations mentioned that size_iops_sec is "burst bucket size"

  https://docs.openstack.org/cinder/latest/admin/basic-volume-qos.html

  but in libvirt documentations is: "The optional size_iops_sec element
  is the size of I/O operations per second"

  https://libvirt.org/formatdomain.html

  and in qemu documentations "iops-size" described as "This setting specifies the size (in bytes) of an I/O
  request for accounting purposes. Larger requests will be counted
  proportionally to this size."

  https://github.com/qemu/qemu/blob/master/docs/throttle.txt

  so I think it is not related to burst bucket size.

  and of course we do not have support for *_max_length parameters for
  burst duration in nova.
