It enables you to passthrough usb devices in qemu/kvm via: On top of the hostdev passthrough (but it's actually totally independent) I added usb massstorage backed by a file. Very handy for installer testing where the preseed data is on the USB stick and the CD/DVD is the installation medium. At the moment I'm using a dummy target "usbdisk" so we don't have to check for target == NULL in that many places. Once qemu handles it we can fill in bus and device address for unplugging. To add a file as usb massstorage to the guest you can use:
<disk type='file' device='disk'> <source file='/foo/bar/usbmass.img'/> <target bus='usb'/> </disk> Does this make sense? -- Guido
