Although I would have liked to see a bit more verbose comments/function
intros, it's not something that I'd stop progress for...

FWIW: w/r/t my comment in v4 patch 9 regarding
qemuxml2argv-usb-hub-autoadd.xml. I too don't get an error (per se) any
more...  If I change the "index='0'" to be "index='1'" and add the
PIIX3_USB_UHCI and PCI_MULTIFUNCTION caps for the test, I now get a
different .args output.  I think it's correct, but I'm sure you can have
a look see with just that much information...

In any case,

ACK series,

John
