  6. Examine File Paths: Within the VMX file, look for any file paths related to virtual disks (.vmdk files), ISO images, or other resources. Ensure these paths are correct and accessible. Pay special attention if you have recently moved the virtual machine or its files. Correct any incorrect paths within the VMX file using the text editor and save the changes.

After verifying and correcting the VMX file path, try starting the virtual machine again to see if the error is resolved.

3. Edit the VMX File for Restriction and VMCI Settings

Modifying specific settings within the VMX file can sometimes resolve issues related to virtual machine startup, especially concerning restrictions and communication channels. Two settings that are often relevant in resolving “VMX binary missing” or startup problems are monitor_control.restrict_backdoor and vmci0.present.

Understanding the Settings:

  • monitor_control.restrict_backdoor: This setting controls the “backdoor” communication channel between the guest operating system and the hypervisor. When set to "true", it restricts this channel, potentially causing issues if certain communication pathways are blocked. Setting it to "false" can sometimes alleviate these restrictions.
  • vmci0.present: VMCI (Virtual Machine Communication Interface) enables fast and efficient communication between the virtual machine and the host operating system, as well as between virtual machines on the same host. While generally beneficial, in some cases, VMCI can cause conflicts or issues. Disabling it by setting vmci0.present to "false" can help troubleshoot startup problems.

Steps to Edit the VMX File:

  1. Locate the VMX File: Navigate to the virtual machine’s folder as described in the previous step (C:\Users\<username>\Documents\Virtual Machines\<Virtual Machine Name>).
  2. Open VMX File with Text Editor: Right-click on the .vmx file and open it with a text editor like Notepad.
  3. Find and Modify monitor_control.restrict_backdoor: Search within the file for the line monitor_control.restrict_backdoor = "true". If you find it, change the value to "false" so it reads monitor_control.restrict_backdoor = "false". If the line is not present, you can skip this step.
  4. Find and Modify vmci0.present: Search for the line vmci0.present = "true". If found, change it to vmci0.present = "false". If this line is also absent, skip this step.
  5. Save the VMX File: After making the necessary changes, save the modified VMX file and close the text editor.
  6. Attempt to Start the Virtual Machine: Try starting your virtual machine in VMware Workstation again to check if the error is resolved.

Caution: Modifying VMX files involves changing the configuration of your virtual machine directly. Ensure you are making changes carefully and only to the specified settings. Incorrect modifications can potentially lead to other issues. If you are unsure about making these changes, consider backing up your VMX file before editing.

4. Change the Virtual Machine’s Disk Image (VMDK)

In scenarios where the VMX file itself might be corrupted or the virtual machine configuration is somehow damaged, creating a new virtual machine and utilizing the existing virtual disk (VMDK) file can be an effective solution. This approach bypasses potential corruption issues in the VMX file or virtual machine settings while preserving your virtual machine’s data and operating system.

Steps to Change the Disk Image:

  1. Create a New Virtual Machine: Open VMware Workstation and initiate the process of creating a new virtual machine. Follow the wizard, selecting the option for a custom configuration if prompted, to have more control over the settings.
