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.I have a bit of trouble parsing that last sentence: Do you mean a loadparm other than 'prompt' will disable the menu and just boot the specified entry, without any delay? (That's what would make most sense to me.)
Correct. If loadparm is given boot index, we simply boot that entry. I like "a loadparm other than 'prompt' will disable the menu and just boot the specified entry"... I hope you don't mind if I steal it ;)
