VioGpuDod error 0xc00000e5

[sebastian-de]

Describe the bug The VM display is not resized with the Window and the displayed VM output seems to be scaled down (see screenshot, taken on a 1920x1200 screen and the VM resolution set to 1680x1050).

Device Manager shows the following error for the Virtio graphics card:

Expected behavior The VM display resolution is set to the current window size, output is not scaled.

Can you please check if installing vgpusrv service ( https://issues.redhat.com/browse/RHEL-62926 ) helps to solve the problem? On Windows 11 you need to copy viogpudo\w11\amd64\viogpuap and viogpudo\w11\amd64\vgpusrv binaries to c:\windows\system32 directory and then, from the elevated cmd prompt, go to this directory and run the following command "vgpusrv.exe -i"

BR, Vadim.

Thanks. I did the following:

PS C:\Windows\system32> cp "F:\viogpudo\w11\amd64\vgpusrv.exe" .
PS C:\Windows\system32> cp "F:\viogpudo\w11\amd64\viogpuap.exe" .
PS C:\Windows\system32> vgpusrv.exe -i
Service Installed
Service is starting...
Service RUNNING.

The output looks fine, but scaling still doesn't work.

@sebastian-de

What kind of scaling do you mean? The virtio-gpu driver itself doesn't support "hardware" scaling https://github.com/virtio-win/kvm-guest-drivers-windows/blob/master/viogpu/viogpudo/viogpudo.cpp#L612

But VNC scaling should work fine

Sorry, I meant "Autoresize VM with window". What I expected was, that the VM display is set to the resolution, the Virt-Manager Window has. So that I can use my native resolution and there is no scaling needed at all. I thought this was possible with the virtio drivers.
