Ouch. Doesn't this mean you are defining a boolean option (absent or
present) as opposed to a qemuOpts option? I've already been complaining
that other boolean opts are currently undiscoverable to QMP; they also
have the drawback of having no way to turn the option back off if an
alias turned it on earlier in the command line. Can we use qemuOpts
here (so query-command-line-options can see it), and with a boolean
on/off argument (so it's not a one-way switch)?
