Hi,
You may need to explicitly use the Q35 chipset in your VM for this to work?
See https://bugzilla.redhat.com/show_bug.cgi?id=1527860
You can select the chipset of your VM in the advanced properties on the
system tab.
Regards,
Rik

Hi,
This is supported in newer versions of oVirt than 4.1.
That's strange, i was using ovirt 4.3, I just added below extra
configruation.
[root@d0248f99ff ~]# cat
/etc/ovirt-engine/osinfo.conf.d/01-usb3.0.properties | grep -v ^#
os.other.devices.usb.controller.value = nec-xhci
then after i enabled *USB-support *, it becomes back to 4
ich9-usb-uhci like below.

Back then, we used a custom hook to replace the USB controller in the
xml file on VM start, but it sometimes caused other issues.
hook could be last option.

Hi,
I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1
with USB redirection enabled.
I've created the following file in /etc/ovirt-engine/osinfo.conf.d:
01-usb.properties with content
os.other.devices.usb.controller.value = nec-xhci
and have restarted ovirt-engine.
If I disable USB-support in the web interface for the VM, the xhci
controller is added to the VM (I can see it in the qemu-kvm
commandline), but usb redirection is not available.
If I enable USB-support in the UI, no xhci controller is added (only 4
uhci controllers).
Is there a way to make the controllers for usb redirection xhci
controllers?
Regards,
Rik
