[Qemu-devel] [PATCH v4] block: qemu-iotests for vhdx, read sample dynami


From: Jeff Cody
Subject: [Qemu-devel] [PATCH v4] block: qemu-iotests for vhdx, read sample dynamic image
Date: Fri, 27 Sep 2013 08:48:15 -0400

This adds the VHDX format to the qemu-iotests format, and adds
a read test.  The test reads from an existing sample image, that
was created with Hyper-V under Windwos Server 2012.

The image file is a 1GB dynamic image, with 32MB blocks.

The pattern 0xa5 exists from 0MB-33MB (past a block size boundary)

The pattern 0x96 exists from 33MB-66MB (past another block boundary,
and leaving a partial blank block)

>From 66MB-1024MB, all reads should return 0.

Although 1GB dynamic image with 66MB of data, the bzip2'ed image
file size is only 874 bytes.

This also adds in the IMGFMT_GENERIC flag, so r/o images can be
tested (e.g. ./check -vhdx) without failing tests that assume
r/w support.
