From 9769e7ac9ff2005316a655365c72c12a40579195 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Wed, 6 Nov 2013 16:53:39 +0100 Subject: [PATCH 82/87] qemu-iotests: Additional info from qemu-img info RH-Author: Max Reitz Message-id: <1383756824-6921-17-git-send-email-mreitz@redhat.com> Patchwork-id: 55571 O-Subject: [RHEL-7.0 qemu-kvm PATCH v2 16/21] qemu-iotests: Additional info from qemu-img info Bugzilla: 980771 RH-Acked-by: Kevin Wolf RH-Acked-by: Fam Zheng RH-Acked-by: Jeffrey Cody BZ: 980771 Add a test for the additional information now provided by qemu-img info when used on qcow2 images. It also tests the qemu QMP output from the query-block command when running qemu with different runtime options than specified in the image (ImageInfoSpecific should always refer to the image).
