Well, it will return "the size reserved on disk" refer to its man page. You
can use --output json to get the actual-size:
# qemu-img info  /var/lib/libvirt/images/raw --output=json
{
    "virtual-size": 10737418240,
    "filename": "/var/lib/libvirt/images/raw",
    "format": "raw",
    "actual-size": 1421459456,
    "dirty-flag": false
}

Remember to add -U option if the images is used by other qemu related
process since qemu-2.10 due to the qemu image locking.
