Overview
qemu-img is a command-line tool used to create, format, convert, modify and verify virtual machine images offline. It can handle all image formats supported by QEMU.
qemu-img must not be used to modify images in use by a running virtual machine or any other process - this may destroy the image. If an image is queried while it is modified by another process may result in an inconsistent state.
