I spoke to cborntra, and it turned out that this affects only guests with zipl with: 86856f98 "zipl: Make use of __noreturn macro" but not yet: c367a6bb "zipl/libc: libc_stop move 'noreturn' to declaration"
That means 2.12/2.13 and that translates to Focal. Therefore retry this as: ubuntu@s1lp5:~$ virt-install --name testinst2 --memory 2048 --disk path=/dev/disk/by-path/ccw-0.0.151e --cdrom /var/lib/libvirt/images/ubuntu-20.04-legacy-server-s390x.iso - all defaults - - install as "entire disk - Then on reboot I get still what seems working: ``` The system is going down NOW! Sent SIGTERM to all processes Sent SIGKILL to all processes Requesting system reboot Domain creation completed.ts; <Enter> activates buttons Restarting guest. Connected to domain testinst2 Escape character is ^] Booting entry #0 ``` We talked further and it is also compiler specific. Eventually any guest "could" fail and it definitely is wise to fix this. Just verification gets harder. I'll try some other ISOs as instructed by Christian to see if one can be used as repro case. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1921468 Title: [UBUNTU 20.04] KVM guest fails to find zipl boot menu index To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1921468/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
