Hi
I have been trying to setup a qemu session for qemu-system-s390x (on
x86_64) using a kernel (with initramfs built-in the kernel) without a
disk image. The kernel was built with s390 defconfig + disabled loadable
modules (just to keep everything inside the kernel).
$ qemu-system-s390x -M s390 -kernel vmlinux -m 1024
The session dies in say 2 secs, with an exit code of 0. I searched for
some hints / success stories, couldn't find any.
Am I doing something wrong here ? Please let me know the right procedure
for getting this up and running.
S390 boots using an "image" file. Please try -kernel <kernel
dir>/arch/s390/boot/image.
Tried that even, but not any better. btw, moved to the upstream git for
qemu.
