[libvirt] USB pass-through with XEN



Hello everybody,

I try to doing USB pass-through with XEN hypervisor using libvirt and i
get the following error:

# virsh attach-device c6test /tmp/usb_device.xml 
error: Failed to attach device from /tmp/usb_device.xml
error: unsupported configuration: unsupported device type

# cat /tmp/usb_device.xml
    <hostdev mode='subsystem' type='usb' managed='yes'>
      <source>
        <vendor id="0x0529" />
        <product id="0x0001" />
      </source>
    </hostdev>

But using xm command, the USB pass-through has been successfully

# xm usb-add c6test host:0529:0001

I try it on Fedora 17 with libvirt 1.0.4 and xen 4.2.1.

Does anyone know how can i do to put libvirt work with XEN USB pass-through?

Best regards,
