[libvirt] RE: [et-mgmt-tools] attach hot usb device



No go for me, maybe I'm running the wrong version of virsh?

virsh # attach-device XPJohn usbPhone2.xml
libvir: QEMU error : unknown device type
error: Failed to attach device from usbPhone2.xml

virsh # version
Compiled against library: libvir 0.4.0
Using library: libvir 0.4.0
Using API: QEMU 0.4.0
Running hypervisor: QEMU 0.9.1

[root e6400:/etc/libvirt/ 482]$virsh list
Connecting to uri: qemu:///system

  2 ubuntuVNC            running
  3 webserver            running
  4 XPTest               running

[root e6400:/etc/libvirt/ 481]$cat usbPhone2.xml
<hostdev mode='subsystem' type='usb'>
      <source>
        <address bus='7' device='4'/>
      </source>

What am I doing wrong?
