The isolinux.cfg:
timeout 50
display /boot/message
default normal
prompt 1
label normal
kernel /boot/vmlinuz
append single rootfstype=iso9660 root=/dev/cdrom rootdelay=30
label safe
kernel /boot/vmlinuz
append single rootfstype=iso9660 root=/dev/cdrom rootdelay=30 acpi=ht
label rescue
kernel /boot/vmlinuz
The image boots OK in QEMU.
