Set boot menu options for an s390 guest and store them in
the iplb. These options are set via the QEMU command line
option:
-boot menu=on|off[,splash-time=X]
or via the libvirt domain xml:
<os>
<bootmenu enable='yes|no' timeout='X'/>
</os>
Where X represents some positive integer representing
milliseconds.
