Feb 08:55 /dev/sda The original file of a snapshot needs only read access, but QEMU tries read/write access and fails. Variants of above command using -hda or -drive also fail with the same error message. I did not test whether the regression affects other kinds of images, too. Maybe only raw images trigger no longer work. Regards Stefan Weil
