If you need to add or change a virtual machine's configuration option that cannot be accessed from elsewhere in the management interface, you can edit the virtual machine's configuration file (.vmx) from the Options tab.
Caution: You should not add or change any options in your configuration file unless you have been given specific instructions about an option in another part of the user documentation, or if you are working with VMware support to solve an issue with your virtual machine.
To add an option to the configuration file, make sure you are logged onto the management interface as the virtual machine user or as a user with the proper permissions to modify this virtual machine (such as the Administrator or root user), then complete the following steps. Make sure the virtual machine is powered off.
To change an option in the configuration file, complete the following steps.
