Subject: [PATCH 25/25] block: vhdx qemu-iotest - log replay of data sector

RH-Author: Jeffrey Cody <jcody@redhat.com>

O-Subject: [RHEL7 qemu-kvm PATCH 25/26] block: vhdx qemu-iotest - log replay of data sector
Bugzilla: 879234

This tests the replay of a data sector in a VHDX image file.

The image file is a 10G dynamic image, with 4MB block size.  The
image was created with qemu-img, and the log left unplayed by
modification of the vhdx image format driver.

It was verified under both QEMU and Hyper-V that the image file,
post log replay, matched.

(cherry picked from commit e78835b722eb26f5a56370166e99b69e9751ea2a)

Conflicts:

RHEL7 Notes: Conflict due to test number leapfrogging tests that have
             not yet been backported into RHEL7.
