From b783e409bf17b92f4af8dc5d6bd040d0092f33e0 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 12 Jan 2010 12:55:16 +0100 Subject: block: Introduce BDRV_O_NO_BACKING If an image references a backing file that doesn't exist, qemu-img info fails to open this image. Exactly in this case the info would be valuable, though: the user might want to find out which file is missing. This patch introduces a BDRV_O_NO_BACKING flag to ignore the backing file when opening the image. qemu-img info is the first user and provides info now even if the backing file is invalid.
