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 <kwolf@redhat.com>

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).
