Comment 11 for bug 1200800

I was finally able to get on the system that was having issues and learned a lot.

First, they weren't even using the storwize_svc driver. They were just using LVM. This, however, wasn't all bad as it was easy to see that, eventually, both storwize_svc and LVM eventually end up in fetch_to_raw. I was able to apply the same idea proposed above (adding a raw_images_only boolean to the config file) in image_utils and then change the flow of fetch_to_raw based on that setting. That got things to work on systems without qemu-img.

To me this seems like it would be the broadest coverage while being the least intrusive. I have some error checking to work out and probably a unit test or two to work on before I can upload a patch, but I think I am getting close to something here. :-)
