Which version of QEMU are you using? Bluetooth support has been completely
removed in QEMU v5.0.0 (which was released more than two years ago already)
since nobody spoke up saying that they were still using the completely
bit-rotten code. So sorry, but it's gone now and cannot be used anymore in
recent versions.

If you just need access to real bluetooth devices in the guest, you could
try to passthrough a real bluetooth USB device to the guest instead.
