Ok @abc,

All USB devices are connected to sys-usb, then you can say that an USB device should be dedicated to another VM. Here we want to say to sys-usb to dedicate the USB NIC to sys-net.

You can do this with the qvm-usb attach or with the Qubes Device Manager.

Preconditions:

  • sys-usb should detect the USB NIC when you plug it, is it OK ? Unplug the USB NIC, in sys-usb terminal launch the sudo dmesg -Tw command then plug the USB NIC. Do you see similar logs as in my previous post? If you are not sure, post the interesting output.
  • the Qubes Device Manager display the USB NIC. Is it OK? Should be like the step 2 on this screenshot
  • sys-usb display the USB NIC. Is it OK? In sys-usb terminal launch the lsusb command, you should see a line with your USB NIC

Now the attach.

Solution 1: attach by Qubes Device Manager

Like in the step 2 of the screenshot, you should select your USB NIC, and in sub-menu choose sys-net.

You should see a Notification : Attaching to sys-net.
In sys-net terminal launch the lsusb command, you should see a line with your USB NIC. And always in sys-net, ip a should list a new network device (ex: eth0 or another name).
