These patches implement a boot menu for ECKD DASD and SCSI guests on s390x.
The menu will only appear if the disk has been configured for IPL with the
zIPL tool and with the following QEMU command line options:
-boot menu=on[,splash-time=X] and/or -machine loadparm='prompt'
or via the following libvirt domain xml:
<os>
<bootmenu enable='yes' timeout='X'/>
</os>
or
<disk>
...
<boot order='1' loadparm='PROMPT'/>
</disk>
Where X is some positive integer representing time in milliseconds.
Loadparm will override all boot options.
