I just updated an Ubuntu Oneiric to Raring and the VM that works fine on one fails to start a VM with this passthrough: <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x055f'/> <product id='0x040b'/> <address bus='3' device='8'/> </source> </hostdev> It just dies at boot time. _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
