Title:
  Password not injected when used images_type = flat and QCOW2 image

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Hi
  We need setup that will copy a whole image from _base for fully independedt instance ephemeral disks, so we decided to use images_type = flat
  But we got a bug at password injection stage with a lot of messages that tell about raw disk type (but it is qcow2 actually!).
  Images are based only on QCOW2.

  Nova: 23.0.1
  Libvirt: 6.0.0
  Virt: Libvirt+KVM
  Storage: Ephemeral local disks

  *nova.conf*

  images_type = flat
  use_cow_images = true #(or false, doesn't matter)
  force_raw_images = false

  Please use gist for better representation:

  The most embarassing thing that it is logging about raw format, but
  all images is QCOW2 format and also at disk.info also qcow2 format.
  Mostly it is bug.
