Hi 116348def2bb446d972bdc2f44bd77ff631f85de works on s390/kvm, but on startup parts of the console output is lost. The used kernel is a standard Debian distribution kernel.
| $ ./s390x-softmmu/qemu-system-s390x -nographic -enable-kvm -kernel /boot/vmlinuz-2.6.32-4-s390x -initrd /boot/initrd.img-2.6.32-4-s390x -append "break=premount" | [ 0.583078] cio: Channel measurement facility initialized using format basic (mode autodetected) | [ 0.585475] TCP cubic registered Everything up to the first line is lost on the virtio console. This could be also a kernel problem as this kernel includes two drivers responsible for hvc, virtio and iucv. The last line in the kernel log before the properly shown ones is: | [ 0.592667] hvc_iucv: The z/VM IUCV HVC device driver cannot be used without z/VM Bastian -- No one can guarantee the actions of another. -- Spock, "Day of the Dove", stardate unknown
