cannot boot windows 7 with qxl drivers

[muelli]

I have a vanilla windows 7 from modern.ie (apparently "version 20150916") and once I install the QXL driver from virtio-win-0.1.141.iso
(43aefa812c37342cfefc48ec0dd7f1e56a930fcd) the machine doesn't boot anymore. The situation doesn't change if I install all the available Windows updates.

STOP 0x0000007F (0x0000000D, 0x0, 0x0, 0x0)

According to https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x7f--unexpected-kernel-mode-trap it indicates a "Bug Check 0x7F: UNEXPECTED_KERNEL_MODE_TRAP" with "0x0000000D -- An exception not covered by some other exception; a protection fault that pertains to access violations for applications".

Once I change the video mode from QXL to, say, virtio, I can boot.

I thus suspect the QXL driver to be the cuprit.
Interestingly, using the "Windows guest tools - spice-guest-tools" from https://www.spice-space.org/download.html seems to work better. But it's unfortunate to download the stuff from there, because it requires a network connection. And Windows does not have virtio network drivers by default.

Hi @muelli ,

In order to debug this efficiently can you please provide me with the following information:

• Command line for running the machine?
• Qemu version

I want to try and reproduce this,
Thanks for reporting the issue =)

[muelli]

I managed to reproduce like this.

I booted the vanilla image off modern.ie: b84bbeb6ef1acd71819ab2eea12ea535b39a5f9b win7-ie11.vanilla.qcow2

through virt-manager, which seems to call out like that:

Note that I have two graphics adapters because I thought I'd have a fallback in addition to the QXL one.

After the first boot it installs some drivers and wants to restart. Then it comes up and has a few drivers missing. Fair enough. I install them from the attached CD-ROM drive. Except for the "Video Controller"! That somehow fails.

After another reboot I force the installation of updates through the settings panel

After a reboot I installed the guest agent

I then install the QXL driver by updating the driver for the "default video adapter" or something.

Then I remove the virtio graphics adapter through virt-manager, press "reboot", and I see it failing when it tried to start:

I could potentially give you access to the qcow file if you think you need it. It's about 15GB in size. It boots happily when using virtio as the only graphical adapter.

Hi @muelli ,

Thanks for all of this info, I just need one more thing. Can you please share the dump file with us and the driver package that you used.

you can configure windows to save dumps this way:
https://image.slidesharecdn.com/windowsguestdebugging-kvmforum2012-130204094652-phpapp02/95/windows-guest-debugging-presentation-from-kvm-forum-2012-31-638.jpg?cb=1434356706

and then grab the dump file from where it usually resides in c:\Windows\memory.dmp

Thanks!

[YanVugenfirer]

Hi @muelli ,

Can you also please indicate from what directory you are installing the driver?

Thanks,
Yan.

[muelli]

The 100MB memory dump is here: https://send.firefox.com/download/6b8e1e1989/#MCuJ8hlDPNMF-t38i8zOqQ

first click first serve... If you have a suggestion as to where to place that file, I'm happy to upload it there.

Can you also please indicate from what directory you are installing the driver?

I don't understand. I selected "search my local computer" and then "D:" for the CD-ROM drive. I only ever had it install drivers off the CD-ROM drive.

[ybendito]

Looks like by misunderstanding you try to use qxldod driver for Win10/W8.
On Win7 should be used qxl driver for Win7, it is on CD under qxl/w7 directory

[muelli]

Looks like by misunderstanding you try to use qxldod driver for Win10.

hm. Again: I haven't manually selected any driver in particular. I've only ever given it "d:" as a path.

I don't know how to test this now, because I can only boot when the QXL adapter is not present. Then, however, I don't know how to update the QXL driver, because I have nowhere to click "update driver". I could start over with a fresh machine, but maybe we need the current machine still.

I'd consider it a bug if it's selecting the wrong driver, anyway. Maybe it's a Microsoft bug, though.

[ybendito]

You can uninstall the qxldod driver: boot the machine without qxl, then open device manager, select 'show hidden devices', find the QXL adapter and select 'Uninstall' and check 'Remove driver'. On next boot with qxl it will be installed with standard MSFT driver, then you can install proper driver for it.

You should select the correct driver for the correct platform.

Remove the driver using device manager or other tool.

This is a way that Windows selects the INFs. It will get the first one it will found.

then open device manager, select 'show hidden d then open device manager, select 'show hidden devices', find the QXL adapter and select 'Uninstall' and check 'Remove driver'evices', find the QXL adapter and select 'Uninstall' and check 'Remove driver'

I cannot find such a device.

You should select the correct driver for the correct platform.

Is it not possible to ship multiple drivers on the CD-ROM and have Windows select the most appropriate one?
If its not, would it be possible to include the .exe from https://www.spice-space.org/download.html on the CD-ROM? That executable seems to work well.

[ybendito]

With 'show hidden devices' you should see two devices under 'display adapters' - one existing, one not existing, not existing is the one you need to uninstall together with the driver.

[muelli]

ah, with "scan for hardware changes" it detected a standard VGA adapter. Sorry, my Windows-fu isn't very strong.
I uninstalled that new device and try to reboot, but it showed the "Shutting down" screen forever. I forced the machine off and rebooted with a QXL adapter instead of virtio and it booted successfully. It still had a standard VGA compatible adapter and I selected to to update the driver from "D:\QXL\W7".
I then updated the driver and it successfully rebooted.

I appreciate that manually selecting the driver makes this a non-issue. But it's hard for me to tell whether it installs the correct driver.
My life would be a tiny bit happier if I didn't have to manually select this particular driver while all the others seem to install fine when Windows is pointed to the root of the CD-ROM.

[YanVugenfirer]

Glad to hear it worked out for you. In any case, while other drivers might function (for example if you install Windows XP driver on Windows 7 for network adapter) - they might not function in an optimal way. Best regards, Yan.

What's the rationale for closing?

I still think that the experience could be better and maybe investigating the shipping of multiple drivers on the CD-ROM and have Windows select the most appropriate one is one option to make it better. Another might be to include the .exe from https://www.spice-space.org/download.html on the CD-ROM.
You have more knowledge than me in these areas, so I think it's worth sharing that with the closure of this issue.

[sameehj]

I have opened a bug report in the following link:
https://bugzilla.redhat.com/show_bug.cgi?id=1542909

This is not the right place to track this issue, I will update once the bug is resolved.
Thanks!

[sameehj]

@muelli Hi

I have tried to reproduce the issue but I could not, even when selecting the qxldod folder instead of the parent folder which has both qxl and qxldod. Windows doesnt select a driver from the qxldod. Can you please try and point to d:\qxldod and try and install the driver? Does this succeeds?

[muelli]

This is 100% reproducible for me.

I've visited https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ and selected IE11 on Win7 for Vagrant. The download link is https://az792536.vo.msecnd.net/vms/VMBuild_20150916/Vagrant/IE11/IE11.Win7.Vagrant.zip and my sha256sum is 08fcafe549ecffb012de008f2b20930cd6670902bc786d5ab1517862ed478738 /tmp/IE11.Win7.Vagrant.zip.
I unpacked the zip file and untarred the resulting .box file. I then qemu-img convert -f vmdk /tmp/box-disk1.vmdk -O qcow2 win7-ie11.qcow2. Then I virsh define /tmp/win7.xml --validate with the following XML:
