From e78835b722eb26f5a56370166e99b69e9751ea2a Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Wed, 30 Oct 2013 10:44:56 -0400 Subject: 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.
