From ea204ddac7340bfda60cb0b388dbc3ffd77e8be0 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Mon, 15 May 2017 17:47:10 +0100 Subject: [PATCH] qemu-img: fix --image-opts usage with dd command The --image-opts flag can only be used to affect the parsing of the source image. The target image has to be specified in the traditional style regardless, since it needs to be passed to the bdrv_create() API which does not support the new style opts.
