Hi,
qemu-img is only to support create/info and so on whithout writting
operation to the image file.
I have ported the reading operation for a image file form grub2 to
qemu-img. But NTFS document online is not detailed enough, how to do
inorder to achieve the goal of writting to a image file?
If anyone encountered the same problem, please reply to me.
Thanks ahead!
Bruce

Embedding file system drivers in qemu-img is not the right approach. You
need to get the image mapped to a block device on your host (e.g. using
qemu-nbd), so you can use the host's file system drivers.
