This is already possible with http://libguestfs.org/.
Or you can use qemu-nbd to mount the image on the host as explained
here:
http://blog.vmsplice.net/2011/02/how-to-access-virtual-machine-image.html
Although adding file system code to qemu-img integrates this feature
more closely, I think the maintenance overhead and duplication of having
read-only file system implementations is too much. Therefore, I'm
against merge a patch like this.
