Qemu. Windows 11 guest. Custom resolution. QXL driver. Share Mouse clipboard.

Use std VGA with QXL Video Driver (Recommended)

To enable custom resolutions for Windows running in QEMU with the QXL video driver, follow these steps to install the necessary drivers and set up the display:

1. Download the SPICE Guest Tools: The SPICE Guest Tools package includes the QXL driver, which is essential for custom resolutions. You can download it directly from Spice Space under the "Windows installers" section.

2. https://www.spice-space.org/download.html

3. Install the SPICE Guest Tools:

   1. Once downloaded, run the installer in your Windows guest. It will install the QXL driver, SPICE agent, and additional tools that enhance display settings, such as automatic resolution scaling.

   2. If you prefer a silent installation (no prompts), run the installer with the /S switch:

   3.    spice-guest-tools-latest.exe /S
      

4. Enable Auto-Resize and Custom Resolution:

5. After installation, restart the Windows VM. Then, go to the View settings of your virtual machine viewer (such as Virtual Machine Manager) and enable Auto resize VM with window to adjust the VM's display resolution dynamically.

   This should do the job.
