This is good for ppc, but it breaks for pseries:
$ echo 'echo hi;' | ./grub-shell --pseries
WARNING: Image format was not specified for '/tmp/tmp.W9bYMpcqGX' and probing
guessed raw.
Automatically detecting the format is dangerous for raw images, write
operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
qemu-system-ppc64: Property 'pseries-hirsute-machine.via' not found
It ends up being:
timeout -s KILL 60 qemu-system-ppc64 -M mac99,via=pmu -M pseries \
-no-reboot -nographic -monitor file:/dev/null \
-fw_cfg name=etc/sercon-port,string=0 -serial file:/dev/stdout \
-hda /tmp/tmp.i96l2WaBHo -boot c
I think `-M pseries` will override the `mac99` part but not the `via=pmu`.
Kind regards,
Daniel
