Description Tomas Jamrisko 2012-07-11 10:26:52 EDT
Description of problem:
When trying to start a windows guest on rhev31 with Native USB, the machine won't start because of:  

qemu-kvm: -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2: Duplicate ID 'usb' for device

Multiple definitions of usb: 
 -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x5.0x7 -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,multifunction=on,addr=0x5

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create a windows 7 64bit guest virtual machine
2. Set usb to Native
3. Start
Actual results:
Fails after a few seconds

Expected results:
The virtual machine powers up

Additional info: 
According to hansg this shouldn't be there:
 <controller type="usb"> <address  domain="0x0000"  function="0x2"  slot="0x01"  type="pci" bus="0x00"/> </controller>

Comment 3 Oved Ourfali 2012-07-23 07:28:59 EDT
The way I reproduced it:
1. Create a windows 7 64bit guest virtual machine (by default USB will be disabled).
2. Run the VM
3. Stop the VM
2. Set usb to Native
3. Start the VM

Step "2" causes the creation of a default USB controller.
Step "3" causes the creation of proper native-USB controllers.

The fix should be to remove the USB controller created in "2" from the vm_devices table in the database.

It is already acked. Waiting for qa_ack to merge.
