Proxmox Passthrough Thunderbolt to Truenas VM on NUC 13

[platini76]

hello, I want to passthrough the entire thunderbolt controller to my Truenas VM
I had: lspci -nnk

00:0d.0 USB controller [0c03]: Intel Corporation Device [8086:a71e]
DeviceName: Onboard - Other
Kernel driver in use: vfio-pci
Kernel modules: xhci_pci
00:0d.2 USB controller [0c03]: Intel Corporation Device [8086:a73e]
DeviceName: Onboard - Other
Subsystem: Device [2222:1111]
Kernel driver in use: vfio-pci
Kernel modules: thunderbolt
00:0d.3 USB controller [0c03]: Intel Corporation Device [8086:a76d]
DeviceName: Onboard - Other
Subsystem: Device [2222:1111]
Kernel driver in use: vfio-pci
Kernel modules: thunderbolt

I went with this command:

root@pve:~# qm set 106 -hostpci0 00:0d
update VM 106: -hostpci0 00:0d

it seems on but when controller is connected to vm my peripherals owc goes in state off and wont' connect with vm.
can someone help me solve problem?
thanks

What I remember from previous threads about thunderbolt is that passthrough of the controller does not work. Passthrough of the connected devices can work but not hot plug/unplug. Maybe you'll have more luck or someone else has figured out how to do it.
