This avoids auto-detection by qemu-img and so the information will be correct with respect to the actual image format on the storage layer. Should the image not be in the correct format, warn and try again querying as raw, so the image is still listed. The image is present, so it is better if it is listed and for some backwards compatibility. The format is still returned as the matched format in such a case, because that is how the image is treated, even if corrupt. Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>
