I guess the .qmu config files don't work. Attached is the script I use to
give me key=value config files for the command line switches. I've posted
this before but no one took notice then.

I would have said "just search the mail archive for it" but apparently attached
files don't always work ... so in this case it's possible you might have looked
(and even found it) but couldn't download it. I attach it here as text so others
won't have this problem next time.

Since config file support clearly exists for qemu (the bottom of this email
proves it), either accept it/improve it, write your own code to replace it,
or reject it and stop complaining.

Agreed.
