Bluetooth not working on VM but working on host

[MasterG87]

Hi,

I have installed Proxmox 5.3 on my Gigabyte Brixx GB-BLCE-4105. It also has an Intel Bluetooth Wifi Chip called Intel AC 3168 onboard. On the Proxmox host I am able to use the bluetooth device properly and I can find several bluetooth devices with

bluetoothctl - scan on

But If I do the same on my VM with Debian 9 Stretch, "sudo bluetoothctl" and "power on" gives me the output:
"No default controller available".

The same command on the host works properly. Do you have any idea? In my opinion I have the same drivers installed on both.

Regards,
Thomas

the guests do not get access to the hardware of the host

either you use that hardware on the host or you try to pass it through to the vm see https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_pci_passthrough

Ok I tried the settings you proposed and I wasn't able to succeed. I might have picked the wrong ID for the passthrough.


When I do "lspci -nn" on the host, I get:

Which one is the Wifi+Bluetooth card, I want to passthrough? I thought it is 01:00.0, but it is apparently not. I also thought it might be 00.13, but I can add it to the VM Hardware because it doesn't occur in the list of available PCI cards. I know that the Wifi+Bluetooth module is on the PCI card slot.

Here some further details. I activated IOMMU on the host:

dmesg | grep IOMMU

[ 0.000000] DMAR: IOMMU enabled

[ 0.004000] DMAR-IR: IOAPIC id 1 under DRHD base 0xfed65000 IOMMU 1


and this is the output of:

find /sys/kernel/iommu_groups/ -type l

/sys/kernel/iommu_groups/7/devices/0000:00:15.0

/sys/kernel/iommu_groups/5/devices/0000:00:13.0

/sys/kernel/iommu_groups/9/devices/0000:00:1e.0

The command
lspci -n | tail -20

gives me:

00:00.0 0600: 8086:31f0 (rev 03)

00:00.3 0880: 8086:3190 (rev 03)

01:00.0 0280: 8086:24fb (rev 10)

02:00.0 0200: 10ec:8168 (rev 15)




Therefore created the file vfio.conf in /etc/modprobe.d and added the line and rebooted the host:
options vfio-pci ids=8086:24fb






The command "qm set VMID -hostpci0 01:00.0" did not work on the VM console, so I thought I do the passthrough over the web interface by adding the Hardware there. What am I doing wrong?

 

[MasterG87]

I am still unable to figure that problem out. Does anybody has an idea where to look?

 

[Mikus]

Can you post output of the command "hciconfig -a" on Proxmox host? It will show where Bluetooth HW is really attached. If it is attached to USB (it might be), you need to passthrough USB device, not PCI. (hciconfig can be installed via bluez package).

If output in the 1st line will be “Type: Primary Bus: USB”, then post also output of the command “lsusb”.

But I don't really get how this is related to bluetooth. Can you help?


The output of lsusb is:

Ok it was the USB Port. I did the passthrough and Bluetooth works properly. I was looking for a solution for such a long time. Thank you.

>But I don't really get how this is related to bluetooth. Can you help?

hciconfig is used to configure Bluetooth devices and prints name and basic information about all the Bluetooth devices installed in the system.


8087:0aa7 is seems to be your Bluetooth device, you need to passthrough this USB device to your VM via Proxmox GUI in hardware section and choose option "Use USB Vendor/Device ID", choose device - 8087:0aa7. Then check bluetooth device from VM.


This approach worked for me (however I use different motherboard with built-in Wifi+Bluetooth)

Ok es ist tatsächlich der eine USB Port gewesen. Habe ihn durchgereicht und jetzt geht Bluetooth. Oh man hab ich dafür lange gesucht. Vielen Dank.

Super!
