I don't think this is really worth fixing... this seems like one of those 'dont do that' things :) Setting up usb2 with qemu already requires knowing the magic XML incantation to make it work, so it's not like this is intuitive in the first place |
Description of problem: Looks like qemu is sensitive to the order in which the controllers are passed. Passing them in a wrong order causes problems in QEMU. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Tried with two VMs, one in which the order was: <controller index="0" model="ich9-uhci3" type="usb"/> <controller index="0" model="ich9-ehci1" type="usb"/> <controller index="0" model="ich9-uhci1" type="usb"/> <controller index="0" model="ich9-uhci2" type="usb"/> Failed on: qemu-kvm: -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x5.0x2: Parameter 'masterbus' expects an USB masterbus qemu-kvm: -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x5.0x2: Device 'ich9-usb-uhci3' could not be initialized >From the qemu log file: LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin HOME=/root USER=root LOGNAME=root QEMU_AUDIO_DRV=spice /usr/libexec/qemu-kvm -S -M pc-0.14 -cpu kvm64,+lahf_lm,+ssse3,-cx16 -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name usb5 -uuid d15a09b9-dde9-4b0e-8b76-5f7bc22be73a -smbios type=1,manufacturer=Red Hat,product=RHEV Hypervisor,version=6Server-6.3.0.2.el6,serial=44454C4C-4200-104C-8036-B9C04F30354A_84:2b:2b:bf:60:b6,uuid=d15a09b9-dde9-4b0e-8b76-5f7bc22be73a -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/usb5.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=2012-05-16T06:52:23,driftfix=slew -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x5.0x2 -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 virtio-serial-pci,id=v!
