So so far I got: - they fail native on s390 - they fail emulated on aarch64 - they pass emulated on x86_64 Here I am, hunting for an s390x machine. After being burned on x86_64, I start with master, not with my PULL request: (main *)$ ./check 108 -qcow2 QEMU -- "/home/quintela/scratch/qemu/gcc/qemu/all/qemu-system-s390x" -nodefaults -display none -accel qtest QEMU_IMG -- "/home/quintela/scratch/qemu/gcc/qemu/all/qemu-img" QEMU_IO -- "/home/quintela/scratch/qemu/gcc/qemu/all/qemu-io" --cache writeback --aio threads -f qcow2 QEMU_NBD -- "/home/quintela/scratch/qemu/gcc/qemu/all/qemu-nbd" IMGFMT -- qcow2 IMGPROTO -- file PLATFORM -- Linux/s390x s390x-kvm-007.lab.eng.rdu2.redhat.com 5.14.0-284.38.1.el9_2.s390x TEST_DIR -- /home/quintela/scratch/qemu/gcc/qemu/all/tests/qemu-iotests/scratch SOCK_DIR -- /tmp/tmpls01m7ji GDB_OPTIONS -- VALGRIND_QEMU -- PRINT_QEMU_OUTPUT -- 108 fail [08:24:54] [08:24:56] 1.7s output mismatch (see /home/quintela/scratch/qemu/gcc/qemu/all/tests/qemu-iotests/scratch/qcow2-file-108/108.out.bad) --- /home/quintela/code/qemu/qemu/tests/qemu-iotests/108.out +++ /home/quintela/scratch/qemu/gcc/qemu/all/tests/qemu-iotests/scratch/qcow2-file-108/108.out.bad @@ -152,6 +152,8 @@ --- Rebuilding refcount structures on block devices --- +fuse: failed to exec fusermount3: No such file or directory +qemu-storage-daemon: --export fuse,id=fuse-export,node-name=export-node,mountpoint=/home/quintela/scratch/qemu/gcc/qemu/all/tests/qemu-iotests/scratch/qcow2-file-108/fuse-export,writable=on,growable=off,allow-other=off: Failed to mount FUSE session to export { "execute": "qmp_capabilities" } {"return": {}} { "execute": "blockdev-create", @@ -188,4 +190,6 @@ Double checking the fixed image now...

Will post PULL request without the vmstate_register() changes. What is weird to me is that it fails in s390x native, and aarch64 host with s390x tcg. But it works for x86_64 host and s390x tcg. Sniff. Later, Juan.
