Public bug reported:

I tried creating 20GB qcow2 image using --size and the image 
Here are the problems: 
1. the image is not created with the selected size
2. the image is reported as qcow2 in glance-list but qemu-img shows it as raw (since the source image copied is a raw image we seem to be taking that parameter but reporting qcow2). 

This is create-image from an remote image which is raw:
