For the records: I recently found an old bluetooth headset in my rack, and was now curious whether it could be used for passthrough in QEMU. It was quite easy to pair it on the host, but when I then tried to pass it through to the guest, I was not able to make it work. I tried for a couple of hours, but apart from a fake HCI, the guest did not see anything bluetooth related. So I really doubt that the current bluetooth code in QEMU is still usable at all... Thomas
