# Add first display
%osascript add_qemu_display.applescript F0B3F201-7C68-41F8-BDE6-9C63A6EC70E7 --hardware "virtio-gpu-pci"            
000D1CC3-61B4-4A0D-B60E-AE6151248467

# Get display , the id is same

# get display, first display id is different  
%osascript display_qemu_get.applescript alpine-3

# remove display

# get display, id changed again
%osascript display_qemu_get.applescript alpine-3
downscaling filter:linear, upscaling filter:nearest, native resolution:false, hardware:virtio-gpu-pci, id:87C7F14D-8FF0-4D5B-9194-10EA07C67429, dynamic resolution:true

I tried the solution below,
In updateQemuDisplays use updateIdentifiedElements instead of updateElements.
Do same in updateAppleDisplays.

I am not sure what is contributing to cause new id to be generated for every update, this make it harder to track the added display.
Any pointers appreciated.

Script used :

on run argv
  set vmName to item 1 of argv

  tell application "UTM"
      set vm to virtual machine named vmName
      set config to configuration of vm
      set currentDisplay to displays of config

      set newDisplay to ¬
          { ¬
              hardware: "virtio-gpu-pci", ¬
              dynamic resolution: false, ¬
              native resolution: true, ¬
              upscaling filter: "QsLi", ¬
              downscaling filter: "QsNe" ¬
          }
      
      set end of currentDisplay to newDisplay
      set displays of config to currentDisplay
      


      update configuration of vm with config
  end tell
end run
