Suppose I want a guest with two sound cards, both using model='ich6'.
Am I correct that the qemu command line needs exactly one "-device
hda-duplex" to enable sound from either card to get back to the host,
but two "-device intel-hda,..." to implement the two cards in the guest?
If so, this doesn't quite do the right thing (you instantiate the
hda-duplex device twice); you'd need a bool variable set after the first
time you emit this extra device.
I noticed this because it is similar to my smartcard patch, where
-device usb-ccid is needed only once, but -device ccid-card-* is needed
per <smartcard>.
