[Libvir] how to setup usb/serial ports with libvirt & kvm (Fedora 7)

["John Davey" <john davey net au>]

I am experimenting with the following Redhat 9 kvm on Fedora 7.  

How do I add a USB device with Libvirt? Specifically I'd like to add a
usb-serial converter for logging data. "Man qemu-kvm" shows -usbdevice
devname to add a USB device but I cannot find out how to do this with
libvirt.

Regards John
