Hi!
> Maybe this patch helps?
The attached patch is an updated version of your patch. With whis patch I was
able to copy files from one directory to another on a disk image. After
unmounting the image, e2fsck reported no errors on this image. But
unfortunately, booting from this image was not possible. INIT reported a
segmentation violation. Maybe there is something else wrong. But now writing
works much better than before :-)

Jörg
PS: Is there any reason, why qemu copies disk data byte by byte? Calling
iommu_translate only once per page and copying a whole page could speed up
disk access significantly...
