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 527d03f (Sun, 6 Aug 2023 23:12:48 -0700) e2fsprogs v1.47.0-144-g441741fc (Tue, 8 Aug 2023 16:08:52 -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 v6.4.0 (Wed, 19 Jul 2023 14:01:37 +0200) xfstests v2023.08.06-8-gcf2f98559 (Wed, 23 Aug 2023 10:54:26 -0400) xfstests-bld e5bc1f22 (Mon, 14 Aug 2023 11:25:51 -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.
