Ask an Expert How can I change the virtual machine's configuration file? How can I change the virtual machine's configuration file?

Answer:

Use FastSCP to connect to ESX server(assuming SSH is enabled), navigate to the vmx file. Right click on the file to select Edit option.

Also you can do the same for the service console. Use Putty to SSH into your VI3 host. Then, edit your VMX file:
nano -w /<path_to_vmx_file>/<virtual_machine_name>.vmx

Make your changes; CTRL X to exit; Y to save and ENTER to save using the same filename.
