Then omit format=raw. (It's an unusual request, though). Or, as others mentioned in this thread, you can use -snapshot or any other form of overlay image to keep the original image read-only while still providing a read-write image that the guest requires for faithful hardware emulation; and you can always check your overlay after the fact to learn whether sector 0 was changed. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
