Without the fix: 1. spawn guest on bionic $ uvt-kvm create --password ubuntu testguest arch=amd64 release=bionic label=daily 2. migrate it over to a focal system $ virsh migrate --live testguest qemu+ssh://10.102.141.223/system 3. check on focal if the guest arrived e.g. log in $ virsh console testguest testguest login: ubuntu Password: 4. reboot the guest ubuntu@testguest:~$ sudo reboot

[ 178.033556] reboot: Restarting system Without the fix it is stuck there, I verified off PPA https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4161 that the fix helps as expected. I do usually test "virsh shutdown" restart cycles. This seems to indicate it might be worth to add a) sudo reboot cycles b) sudo reboot cycles after migration This might excercise quite some code paths ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896751 Title: Guest hang on reboot after migration from bionic to focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1896751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
