Description Koen van Bakel 2012-09-26 13:40:27 UTC

Description of problem:
I created a Windows 7 64bit VM with Native USB support. (and this VM works correctly) From that VM I created a template. Changed the USB support to Disabled in the template and then defined a VM Pool based on this template. VM's are being created but if I start a VM it will fail.

VDSM log message: virNetClientProgramDispatchError:174 : internal error PIIX3 USB controller must have PCI address 0:0:1.2

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

RHEVM: 3.1.0.14-el6ev

How reproducible:

Always. (I found the bug in my own setup and also in another environment we experiance the same problem.)

Steps to Reproduce:
1.Create Windows 64bit VM - USB support Native
2.Create template based on previous created VM
3.Change template USB support to Disabled
4.Create Pool based on Template
5.Start VM from Pool.

Actual results:
VM from Pool will not start

Expected results:
VM should start correctly

Additional info:

I did some additional scenario testing:

1. Base VM Windows 64 bit: USB Disabled
Template : USB Disabled
Pool : USB Disabled

Result: VM starts correctly.

2. Base VM Windows 64 bit: USB Disabled
Template : USB Disabled
Pool : USB Native

Result: VM fails to start.
Additional info: in this last scenario you get a different message in the log: virNetClientProgramDispatchError:174 : internal error Process exited while reading console log output: qemu-kvm : -device piix3-usb-uhci, id=usb, bus=pci.0,addr=0x1.0x2:Duplicate ID 'usb' for device.
