These KVM test appliance images are designed to be used with the kvm-xfstests system which can be found here: git://git.kernel.org/pub/scm/fs/ext2/xfstests-bld.git If you are testing a 32-bit x86 kernel you must use the root_fs.img.i386. If you are using a 64-bit x86 kernel, you may use either the i386 or x86_64 root_fs.img file. Information on how to use these images can be found at the Quick Start guide, located at: https://github.com/tytso/xfstests-bld/blob/master/Documentation/kvm-quickstart.md The "corresponding source" of the GPL binaries found in these KVM images can be found in the source packages from this snapshot of Debian distribution's "bookworm" release: https://snapshot.debian.org/archive/debian/20230706T205036Z/ ... as well as the following git repositories: blktests 30bdcb7 (Tue, 4 Jul 2023 17:30:26 +0900) e2fsprogs 1.47.0-2-4-gd4745c4a (Tue, 30 May 2023 16:20:44 -0400) fio fio-3.35 (Tue, 23 May 2023 12:33:03 -0600) fsverity v1.5-7-g585e14a (Wed, 5 Jul 2023 20:46:59 -0700) ima-evm-utils v1.5 (Mon, 6 Mar 2023 07:40:07 -0500) nvme-cli v1.16 (Thu, 11 Nov 2021 13:09:06 -0800) quota v4.05-53-gd90b7d5 (Tue, 6 Dec 2022 12:59:03 +0100) util-linux v2.39.1 (Tue, 27 Jun 2023 14:31:13 +0200) xfsprogs v6.3.0 (Mon, 22 May 2023 11:50:36 +0200) xfstests v2023.07.23-7-g346f3cd9c (Mon, 24 Jul 2023 21:14:11 -0400) xfstests-bld 8aaca0f1 (Mon, 24 Jul 2023 21:32:46 -0400) zz_build-distro bookworm The gen-image script found in the test-appliance directory of the xfstests-bld git repository, plus Debian bookworm's debootstrap, constitutes the scripts used to control the creation of these KVM images.
