From 497a30dbb065937d67f6c43af6dd78492e1d6f6d Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Mon, 3 May 2021 14:36:00 -0700 Subject: qemu-img: Require -F with -b backing image Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F), we deprecated the ability to create a file with a backing image that requires qemu to perform format probing. Qemu can still probe older files for backwards compatibility, but it is time to finish off the ability to create such images, due to the potential security risk they present. Update a couple of iotests affected by the change.
