Description of problem: When I want to use a usb1.1 device only with model ich9-uhci1/2/3, it report error virsh create test1.xml error: Failed to create domain from test.xml error: internal error process exited while connecting to monitor: qemu-kvm: -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,addr=0x2: Parameter 'masterbus' expects an USB masterbus qemu-kvm: -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,addr=0x2: Device 'ich9-usb-uhci1' could not be initialized Seems libvirt will automatically add masterbus for this model If this model can only used with masterbus, then it should report error when edit/define xml.

Should it support only using one of ich9-uhci[1-3] usb controller, or these controllers must be used as companion controllers ,it will give clear error message if only use one of them. Thanks a lot.

It will be OK when define /edit. and will give error when I try to start guest: 2015-09-01T02:09:19.740992Z qemu-kvm: -device ich9-usb-uhci1,masterbus=usb1.0,firstport=0,bus=pci.0,multifunction=on,addr=0xb: USB bus 'usb1.0' not found 2015-09-01T02:09:19.741030Z qemu-kvm: -device ich9-usb-uhci1,masterbus=usb1.0,firstport=0,bus=pci.0,multifunction=on,addr=0xb: Device 'ich9-usb-uhci1' could not be initialized I was wondering if this is an expected result.

I think it is, because in qemu ehci and uhci are companion controllers. Therefore you need to add an ehci1 controller with index=1 to be able to boot. Michal
Thanks for your info. According to comment 12 and comment 14 , ich9-uhci[1-3] as a companion controllers cannot only use one of them. it has clear error message now. move this bug to verified.
