Public bug reported:

Using openstack queen version:

Uploaded qcow2 image to glance

openstack image create --disk-format=qcow2 --container-format=bare
--file img/ylinux-7.4.4_236.qcow2 ylinux-7.4.4

and created an instance

openstack server create test_queens_f --flavor small --image
ylinux-7.4.4


After creating the image and try to create an instance 
The selected Compute node will download the image from glance and 
Convert it using the command 
qemu-img convert -t none -O raw -f qcow2 {file} {file}
to produce a RAW image from qcow2

although in the configuration we set:
use_cow_images = true
force_raw_images = false
images_type = qcow2

in nova.conf and nova-compute.conf


i think using the options above should stop the convert to RAW
