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

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.

not yet been backported into RHEL7.
