[Bug 1069302] [NEW] kvm client does not start with pci passthrough (amd hd5450)

Sun Oct 21 07:36:17 UTC 2012

Public bug reported:

Within Quantal I cannot start a kvm client using graphical card (amd hd
5450) (anymore). I can start a different client using a differrent
device (usb device)

I've had this machine running under Quantal with the pci device assigned and was still trying to verify it's proper operation. 
- It could be due to an xorg update within Quantal that I'm having problems now, but I've unassigned the device
- It could be due to a kernel update within Quantal, I'm seeing a kernel BUG line within dmesg

Under 12.04 this client machine just can be started.

The message shown by virt-manager, on starting the machine:
Error starting domain: Timed out during operation: cannot acquire state change lock

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 117, in tmpcb
    callback(*args, **kwargs)

    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: Timed out during operation: cannot acquire state change lock

An extract from dmesg (grep -i msi) the device I'm trying to assign is 0000:06:00.0
(device 0000:03:00.0 is the usb device for the other machine that does work)
