From 6f176b48f9f98820ed192a1355cc1c7c08ddf46b Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Tue, 3 Sep 2013 10:09:50 +0200 Subject: block: Image file option amendment This patch adds the "amend" option to qemu-img which allows changing image options on existing image files. It also adds the generic bdrv implementation which is basically just a wrapper for the image format specific function.
