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/20250309T100353Z/ ... as well as the following git repositories: blktests 9aa2023 (Tue, 15 Apr 2025 14:41:27 +0900) fio fio-3.39 (Tue, 18 Feb 2025 08:36:57 -0700) fsverity v1.6-2-gee7d74d (Mon, 17 Feb 2025 11:41:58 -0800) ima-evm-utils v1.5 (Mon, 6 Mar 2023 07:40:07 -0500) libaio libaio-0.3.108-82-gb8eadc9 (Thu, 2 Jun 2022 13:33:11 +0200) ltp 20250130-235-g037cb53e3 (Fri, 25 Apr 2025 14:10:18 +0200) quota v4.05-71-g4cd93fc (Sun, 27 Apr 2025 08:24:24 -0400) util-linux v2.41-36-gd828cc20f (Tue, 22 Apr 2025 12:27:10 +0200) xfsprogs v6.14.0 (Tue, 8 Apr 2025 16:14:30 +0200) xfstests v2025.04.27-11-g5138417b1 (Sun, 27 Apr 2025 19:07:39 -0400) xfstests-bld gce-xfstests-20250411-16-gd513b388 (Tue, 29 Apr 2025 22:05:25 -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.
