Description of problem: The PCI standard RAM Controller driver has the Location information the same as PCI device that kvm/qemu set for the memory ballooning driver (my test, PCI bus 0, device 5, function 0). How reproducible: Try to install balloon driver following these steps: 1) # yum install virtio-win 2) Mount /usr/share/virtio-win/virtio-win.iso as CDROM to W2008 vm. 3) Copy from CDROM the Ballon Directory to C: 4) Download devcon utility and copy it to C:\Balloon\2k8\x86\ http://support.microsoft.com/kb/311272 5) Start -> Run -> cmd Go to C:\Balloon\2k8\x86\ directory Execute: #devcon install BALLOON.inf "PCI\VEN_1AF4&DEV_1002&SUBSYS_00051AF4&REV_00" #blnsvr -i Actual results: Cannot install balloon driver. Expected results: The balloon driver should install without any conflict. Additional info: Workaround: Start -> Control Panel -> System -> Device Manager -> System devices -> PCI standard RAM Controller On the driver Tab, select Update Driver -> Browse my computer for driver -> Select C:\Balloon\2k8\amd64 Then, from DOS install the service: C:\Balloon\2k8\amd64\blnsvr.exe -i Reboot

Hi Vadim, > Hi Douglas. > Please correct me if I'm wrong, but > do you try to install 32-bit driver on 64-bit platform? Sorry, it was just an example that I took from the previous BZ that I have opened. https://bugzilla.redhat.com/show_bug.cgi?id=666139 which depends on this one. Unfortunately, I don't have permission to edit the entry but the main point here is that it's not possible to install the balloon driver on Windows 2008 x86_64 because of the PCI standard RAM Controller driver. For while, I cannot see this issue on x86 versions. Thanks Douglas

Works like a charm. btw, http://support.microsoft.com/kb/311272 has binaries from 2002. Best regards, Vadim.

Oh nice, you found the x86_64 version. So, if I understood correctly this work without need to update manually the driver? Just executed the devcon binary and worked like a charm? Thanks Douglas

Yes, if you prefer devcon over device manager - you are welcome to use it. Just take one from the recent WDK. On the other hand - you can use device manager. It's just a matter of your choice. After all, both of them use the same functions from SetupApi.dll. Best regards, Vadim.

Great job! Cheers Douglas
With the previous update from Vadim, we can close this ticket. The only one that we can keep is the documentation procedure about the balloon driver. Thanks Douglas
