Hi HN, I built this after hitting a wall with Bluetooth passthrough on Proxmox: Intel's onboard Bluetooth/WiFi combo chips (BE200, AX210, AX211, and others) are built so only the machine that boots them can drive them. Hand the chip to a VM via USB passthrough and it wipes its own firmware, no setting fixes it. It's how the hardware works. Also flaky on gaming distros like ChimeraOS/Bazzite even with add-on dongles :-/
Instead of fighting passthrough, this keeps the adapter on the Proxmox host, let's share it into the VM over the local network via BlueZ. 2 simple commands: run the installer on the host, run it again inside the VM pointing at the host's IP. The VM sees a normal Bluetooth adapter and pairs like usual. Both sides auto-reconnect on reboot.
Works for game controllers in a gaming VM, Home Assistant BLE sensors, headphones, anything that expects a normal adapter.
I would be happy to answer questions about the approach.
