kvm-windows-10-guest-ultrawide-resolution.md

Configure a Windows 10 KVM Guest to use an ultrawide display resolution (3440x1440)

1. virsh edit Windows10
2. Navigate to the <video> section and change it to the following one:

    <video>
      <model type='qxl' ram='131072' vram='131072' vgamem='32768' heads='1' primary='yes'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>

3. Start the VM and install the "Windows guest tools" from Spice Space: https://www.spice-space.org/download.html
4. Shutdown the Windows 10 VM and activate "Auto resize VM with window" via the "Virtual Machine Manager" -> open the VM -> "View" -> "Scale Display" -> "Auto resize VM with window" (https://unix.stackexchange.com/a/589766)
5. Start the VM. It should now automatically be scaled to the max. possible resolution.

Thank you. I'm saving this. It's too easy to lose the virtmanager settings.
