I am starting qemu with a bash script - yqemu - (not written by me).  I 
choose options 2 and 5.  Will also post inline since the list may not 
take attachments:

Since I have an i386 system I ran:

$ ps auxwww | grep qemu-system-i386
<user>    2323  2.1 13.9 712076 560872 ?       SLl  11:40   0:51

Nothing

[         0.9407921] Floppy drive(s):  fd0 is 1.44M


Hope I got all that right.  Looking forward to a followup.
