To fix certain problems with your system, VMware documentation or a VMware Technical Support representative might instruct you to change or add virtual machine configuration parameters.

Before you begin

Power off the virtual machine.

About this task


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 must change the existing value for the keyword/value pair. For example, if the existing pair is keyword/value, and you change it to keyword/value2, the new keyword is 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 might receive a value of 0, false, or disable, which might result in a virtual machine that cannot power on.
