At this point, you can either remove the -nographic or add -append
"console=ttyS0 vga=off" to have the kernel boot logs.
If you want to have started an userspace command, add the initrd from
the CD:
guestfish --add debian-9.0-m68k-NETINST-1.iso --ro \
--mount /dev/sda:/ <<_EOF_
copy-out /install/cdrom/initrd.gz .
_EOF_
