They should use physical addresses, otherwise changing the VM hardware in trivial ways may cause a waterfall effect and cause Windows to reactivate. > If I try to set up virt-manager so that it doesn't point to a file, it > uses this configuration: > > -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x5.0x7 > -device > ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,multifunction=on,addr=0x5 > > -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x5.0x1 > -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x5.0x2 > > This seems to differ from the configuration file, e.g. you have > multifunzion=on only on the first uhci That doesn't matter. > , besides I can't understand how many physical ports are defined. There are 6 ports, controlled by either the EHCI for USB 2.0 devices (the EHCI controls 6 ports) or by one of the three UHCI for USB 1.1 ports (one UHCI has 2 ports). > I tried setting 9 usbredirection > channels in virt-manager but that configuration doesn't change and no > errors are reported, but I doubt that physical ports are being define > dynamically.

It is the same. Paolo
