Fix 2. Adjust VMware Memory Settings

The second method to fix this problem is to power off other virtual machines and then to adjust the additional memory settings to allow more virtual machine memory to be swapped.

Step 1: Open your VMware Workstation and go to Edit > Preferences.

Step 2: Click the Memory option from the left pane and navigate to the Additional memory section.

  • Fit all virtual machine memory into reserved host RAM: you can choose this option if the memory is large enough.
  • Allow most virtual machine memory to be swapped: you can choose this option if the memory is slightly larger and you want the virtual machine to run more smoothly.
  • Allow some virtual machine memory to be swapped: you can choose this option if you have not much memory.

In this step, you can choose the second or third option according to your condition.
