You can change or add virtual machine configuration parameters when instructed by a VMware technical support representative, or if you see VMware documentation that instructs you to add or change a parameter to fix a problem with your system.

About this task

Important:

Changing or adding parameters when a system does not have problems might lead to decreased system performance and instability.

The following conditions apply:

  • To change a parameter, you change the existing value for the keyword/value pair. For example, if you start with the keyword/value pair, keyword/value, and change it to keyword/value2, the result is keyword=value2.

  • You cannot delete a configuration parameter entry.

Caution:

You must assign a value to configuration parameter keywords. If you do not assign a value, the keyword can return a value of 0, false, or disable, which can result in a virtual machine that cannot power on.

Procedure

  1. Right-click a virtual machine in the inventory and select Edit Settings.
  2. Click the VM Options tab and expand Advanced.
  3. Click Edit Configuration.
  4. (Optional) : To add a parameter, click Add Row and type a name and value for the parameter.
