Hello again to you too! :) Thanks for the update and details.
You might try using qemu-img to modify the file before uploading as a new image: https://fatmin.com/2016/12/20/how-to-resize-a-qcow2-image-and-filesystem-with-virt-resize/ http://www.tuxfixer.com/how-to-shrink-openstack-qcow2-image-with-qemu-img/ I think qcow2 image file you copied has embedded metadata that needs to be modified before you can create the image with a smaller --min-disk. I haven't done this myself though, and I am away from a OpenStack console at the moment so I can't verify, but hopefully that gets us one step closer.
