[Qemu-devel] qcow2 corrupted image, no error from qemu-img check |

Hello,
I'm converting some images without problem,
but with one i cannot (vm_import) , due to error.
( this image was creating with qemu 0.14.1 and continue to work,
windows guest image)
So, is it possible to repair this image ?
I know my email is more for qemu user list, but qemu-img check tells
me no error, than qemu-convert return one.
