EcoStruxure Process Expert [2020] Unable to start VM - AHCI Port Reset
This article assists users in recovering and starting a virtual machine (VM) that failed to start while the system server was starting up.
In a normal scenario, when a user attempts to start the server, the virtual machine (VM) should start automatically. However, users may encounter an error where the VM fails to start during the server startup process.
As an initial troubleshooting step, clear the temporary files from the following locations:
- C:\Users\USERNAME\AppData\Local\Schneider Electric
- C:\Users\USERNAME\.VirtualBox
After deleting the temporary files, restart the server and verify whether the VM starts successfully. If the VM still does not start, verify that the following Windows features are disabled (OFF):
- Virtual Machine Platform
- Windows Hypervisor Platform.
To check the status of these features:
- Open Control Panel.
- Navigate to Programs and Features.
- Select Turn Windows features on or off.
- Ensure the features listed above are unchecked.
- Restart the computer after making any changes.
These Windows virtualization features can conflict with Oracle VirtualBox, which is used by EcoStruxure Process Expert 2020 R2 and earlier versions. Disabling them allows VirtualBox to access the hardware virtualization resources required to start the VM successfully.
