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

Hi, This is supported in newer versions of oVirt than 4.1.

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.

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.
