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.


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.


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.


Right-click the virtual machine and select Edit Settings.


To locate a virtual machine, select a datacenter, folder, cluster, resource pool, host, or vApp.


Click the Related Objects tab and click Virtual Machines.


Click the VM Options tab and expand Advanced.


Click Edit Configuration.


(Optional) To add a parameter, click Add Row and type a name and value for the parameter.


(Optional) To change a parameter, type a new value in the Value text box for that parameter.


Click OK.
