It's also used when you reboot. However, there are currently
pre-existing bugs in bootindex handling (especially regarding hotplug
and hot-unplug) that should be fixed before allowing modification of
boot index while the VM is running.
The command to do the modification could be qom-set. We can make the
bootindex property runtime-modifiable.
