I am using backing store when I create my volume. However, the backing store file is from another team, which can be either in raw or in qcow2 format.
Is there a libvirt API to detect image format by given an image file? Or I have to run qemu-img?
Nothing wrong with running `qemu-img info' IMHO. Libguestfs has some disk detection features, including format, backing file, virtual size. And of course it can go a lot deeper into the disk content itself using libguestfs inspection.
