From 9188bcfc8f33c9340acdb6279d01d09ca6fec591 Mon Sep 17 00:00:00 2001 From: Jeffrey Cody Date: Wed, 20 Nov 2013 19:43:44 +0100 Subject: [PATCH 01/25] block: qemu-iotests for vhdx, read sample dynamic image RH-Author: Jeffrey Cody Message-id: Patchwork-id: 55794 O-Subject: [RHEL7 qemu-kvm PATCH 01/26] block: qemu-iotests for vhdx, read sample dynamic image Bugzilla: 879234 RH-Acked-by: Stefan Hajnoczi RH-Acked-by: Paolo Bonzini RH-Acked-by: Fam Zheng 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.
