Hi

We are running our VM’s using the KVM driver, just wondering what the easiest way is to set the default usb controller from model piix3-uhci to controller type=‘usb’ index=‘0’ model=‘nec-xhci’ ? So each VM is brought up with a USB 3 controller?

Edit: Think I’ve solved it, needed to add

```auto
 <controller type='usb' index='0' model='nec-xhci'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </controller>
</devices>

```
