This tests the replay of a data sector in a VHDX image file.
0a122b
0a122b
The image file is a 10G dynamic image, with 4MB block size.  The
0a122b
image was created with qemu-img, and the log left unplayed by
0a122b
modification of the vhdx image format driver.
0a122b
0a122b
It was verified under both QEMU and Hyper-V that the image file,
0a122b
post log replay, matched.
