** Description changed: + [Impact] + + * the way libguestfs launches libvirt is not working on s390x + + * backport fixes to work on that platform as well + + * The TL;DR of the changes is to add arch specific options to the calls + being made + + [Test Case] + + * TL;DR: install and use libguestfs-tools on s390x + IBM outlined a test using the libvrtguestfs-test-tool, but that is + just one of too many options to try - find more details in the comments below. + Note: IBM will assist in verifying those and already has on the PPA + + [Regression Potential] + + * This modifies how arguments are created, but it does so only for s390x so the regression should be limited to that architecture. + The issue would be that it doesn't start properly, but since that is the current state there is no real regression - it would just replacve one way of failing for another - and since the tests by IBM on the PPA were good we are convinced that even that regression-risk would not trigger. + + * The FTBFS is a build time only change and should not trigger + regressions later on. + + [Other Info] + + * Along the fix requested this fixes an FTBFS in Bionic due to the move to a new default JDK version. + + --- + The libguestfs versions < 1.37.22 don't work on s390x, as they don't contain the patches which include the s390x specifics to instruct qemu-kvm - correctly. Ubuntu 16.04 contains an older version than that, which makes + correctly. Ubuntu 16.04 contains an older version than that, which makes libguestfs not usable on s390x. - Steps to reproduce ================== A chronological list of steps which will bring off the issue I noticed: - - mz@s390xhost$ docker run -it --privileged --rm ubuntu:xenial bash - root@5dde0aef5d2e:/# - root@5dde0aef5d2e:/# - root@5dde0aef5d2e:/# apt update - root@5dde0aef5d2e:/# DEBIAN_FRONTEND=noninteractive apt install -y \ - libguestfs-tools \ - python-libguestfs \ - linux-image-generic \ - qemu - root@5dde0aef5d2e:/# - root@5dde0aef5d2e:/# - root@5dde0aef5d2e:/# export LIBGUESTFS_DEBUG=1 - root@5dde0aef5d2e:/# export LIBGUESTFS_TRACE=1 - root@5dde0aef5d2e:/# libguestfs-test-tool - + mz@s390xhost$ docker run -it --privileged --rm ubuntu:xenial bash + root@5dde0aef5d2e:/# + root@5dde0aef5d2e:/# + root@5dde0aef5d2e:/# apt update + root@5dde0aef5d2e:/# DEBIAN_FRONTEND=noninteractive apt install -y \ + libguestfs-tools \ + python-libguestfs \ + linux-image-generic \ + qemu + root@5dde0aef5d2e:/# + root@5dde0aef5d2e:/# + root@5dde0aef5d2e:/# export LIBGUESTFS_DEBUG=1 + root@5dde0aef5d2e:/# export LIBGUESTFS_TRACE=1 + root@5dde0aef5d2e:/# libguestfs-test-tool Expected result =============== The libguestfs-test-tool passes and I can use it on s390x. To check if qemu on s390x works independently from libguestfs, I use this command: - root@5dde0aef5d2e:/# qemu-system-s390x \ - -enable-kvm \ - -nographic \ - -kernel /boot/vmlinuz-4.4.0-119-generic \ - -initrd /boot/initrd.img-4.4.0-119-generic \ - -m 1G \ - -M s390-ccw-virtio - - [...] # boot - - BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash) - Enter 'help' for a list of

As an example, the latest known needed patch is [5]. As a smoke test, in case the libguestfs-test-tool result was a false positive, I used the python binding code in Appendix A below, which is based on [6]. FWIW, I checked Ubuntu 18.04 (beta), and it doesn't work there too. The packaged version of libguestfs is v1.36 in 18.04 bionic beaver, which is too old (and/or doesn't contain the needed backports). - References ========== [1] Bug 1376547 - qemu-system-s390x: -device isa-serial,chardev=charserial0, -
