[Qemu-devel] [PATCH v2] qemu-img: Check for backing image if specified during create

2017-05-09 Thread John Snow
Or, rather, force the open of a backing image if one was specified for creation. Using a similar -unsafe option as rebase, allow qemu-img to ignore the backing file validation if possible. It may not always be possible, as in the existing case when a filesize for the new image was not specified.
