[Qemu-devel] [PATCH 2/2] block: add test for vhdx image created by Disk2VHD

[Jeff Cody]

This adds a test for VHDX images created by Microsoft's tool, Disk2VHD.

VHDX images created by this tool have 2 identical header sections, with
identical sequence numbers.  This makes sure we detect VHDX images with
identical headers, and do not flag them as corrupt.
