Description

Set your guest up with a USB3 controller and passthrough a USB3 device to your guest.

Setup

A functioning F18 VM, a host with USB3 ports and a physical USB3 device.

How to test

  • Attach the USB3 device to your host. Make sure it is showing up as USB3 (the 5000M bit at the end):
   $ lsusb -t
   ...
   /:  Bus 09.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/2p, 5000M
        __ Port 2: Dev 4, If 0, Class=Mass Storage, Driver=usb-storage, 5000M
   ...
  • Make sure the VM is stopped. Edit the VM configuration like: 
    virsh edit f18
  • Remove all devices like <controller type='usb... and add the following: 
    <controller type='usb' model='nec-xhci'/>
  • Save and exit. Start the guest, connect with virt-manager and log in to the guest.
  • In the virt-manager hardware view, Add Hardware->USB Host Device, select your USB3 device to attach to the guest.
  • Start the guest, log in. lsusb -t should show the device as USB3 (like above)
  • Verify the device works as expected

Expected Results

No obvious errors occur. USB device is detected as USB3 in the VM, functions correctly, speed increases?
