VMX Builder: Create & Edit VMX Files for VMware Virtual Machines

A Windows application for easy VMX file configuration, offering a GUI interface instead of manual text editing

What is VMX Builder?

VMX Builder is a Windows desktop application designed to simplify the creation and configuration of VMware virtual machine definition files with the .vmx extension. Instead of manually editing the text-based .vmx files, VMX Builder provides a graphical user interface to set up and configure all aspects of a VM.

Key features include:

  • Intuitive wizard-style interface to walk through creating a new .vmx file
  • Form fields and menus to set VM parameters such as number of vCPUs, memory allocation, network type, virtual hard disk type and size, etc.
  • Ability to edit existing .vmx files by importing them into VMX Builder
  • Validation checks to catch configuration errors
  • Export edited .vmx files to use with VMware products like Workstation, Player and vSphere

VMX Builder aims to simplify the virtual machine configuration process, enabling more users to take advantage of VMware virtualization technology. The visual interface and validation features reduce the chances for errors compared to manually editing the text-based files.
