thanks for your answer.
I'm trying to run the following script, but it fails when using automation, but if I run it on the machine directly on the powershell it runs and installs the virtio drivers.
There are several options to run the ps script one of them (Source) is confusing, i've choose local, but the script fails everytime. Tried to change execute target also, but still fails.

# This script assumes the virtio-win.iso is mounted as a CD/DVD drive in the VM.
# --- Configuration ---
$VirtIOIsoDriveLetter = Get-WmiObject -Class Win32_CDROMDrive | Where-Object {$_.VolumeName -like "*virtio-win*"} | Select-Object -ExpandProperty Drive
$VirtIOInstallerPath = "$VirtIOIsoDriveLetter\virtio-win-gt-x64.msi" # Adjust if the executable name is different
$LogFile = "C:\Temp\VirtIO_Installation_Log.txt" # Log file for installation output
# Create Temp directory if it doesn't exist
If (-not (Test-Path "C:\Temp")) {
New-Item -Path "C:\Temp" -ItemType Directory | Out-Null
}
