Description Javier Coscia 2019-03-15 20:40:43 UTC 
Description of problem:

Device Manager in a Windows 10 guest will not list the USB 3.0 eXtensible 
Host Controller when selecting q35 machine type in RHV UI

Version-Release number of selected component (if applicable):

rhvm-4.2.8.3-0.1.el7ev.noarch

How reproducible:

100%

Steps to Reproduce:
1. Build a Windows 10 guest and change its emulated machine type to `q35`
2. Make sure you selected Console > SPICE and USB Support Enabled
2. Start the VM, notice the XML is build with standard ich9-[e-u]hciN controller


Actual results:

engine builds the XML with ich9-[e-u]hciN controllers
USB 3.0 support will not be avialable inside the Windows 10 guest


Expected results:

engine builds XML VM with correct nec-xhci controller

USB 3.0 eXtensible Host Controller should be installed and configured on 
Windows 10 guest if q35 chipset is selected

Additional info:

Workaround, use vdsm hook from https://access.redhat.com/solutions/2789511

q35 settings

To clarify, this is where it should be changed. Not just the emulated machine type
