Re: [libvirt] Rudimentary (basic) s390x architecture functions for libvirt



A few more details for s390x: why you can't set param '-S' and need
'-chardev vc,id=cons -device virtio-serial-s390 -device
virtconsole,chardev=cons' on s390x:

1) qemu-system-s390x -M s390-virtio -vnc :0 -enable-kvm -smp 1 -m 1024
-k de  -kernel /boot/image-2.6.34-tue01 -initrd
/boot/initrd-2.6.34-tue01_GUEST -drive file=/data/sle11.img -append
"root=/dev/vda1 rw"

=> screenshot 1

2) qemu-system-s390x -S -M s390-virtio -vnc :0 -enable-kvm -smp 1 -m
1024 -k de  -kernel /boot/image-2.6.34-tue01 -initrd
/boot/initrd-2.6.34-tue01_GUEST -drive file=/data/sle11.img -append
"root=/dev/vda1 rw"

=> screenshot 2

3) qemu-system-s390x -M s390-virtio -vnc :0 -enable-kvm -smp 1 -m 1024
-k de  -kernel /boot/image-2.6.34-tue01 -initrd
/boot/initrd-2.6.34-tue01_GUEST -drive file=/data/sle11.img -append
"root=/dev/vda1 rw" -chardev vc,id=cons -device virtio-serial-s390
-device virtconsole,chardev=cons

 => RUN

4) qemu-system-s390x -S -M s390-virtio -vnc :0 -enable-kvm -smp 1 -m
1024 -k de  -kernel /boot/image-2.6.34-tue01 -initrd
/boot/initrd-2.6.34-tue01_GUEST -drive file=/data/sle11.img -append
"root=/dev/vda1 rw" -chardev vc,id=cons -device virtio-serial-s390
-device virtconsole,chardev=cons

=> screenshot 4
