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.
