Changing virtual machine power states is useful when you do maintenance on the host. You can use the system default settings for the virtual machine power controls, or you can configure the controls to interact with the guest operating system. For example, you can configure the Power off control to power off the virtual machine or shut down the guest operating system.

You can modify many virtual machine configurations while the virtual machine is running, but you might need to change the virtual machine power state for some configurations.

You cannot configure a Power on (power on) action. This action powers on a virtual machine that is stopped, or starts a virtual machine and runs a script if the virtual machine is suspended and VMware Tools is installed and available. If VMware Tools is not installed, it starts the suspended virtual machine and does not run a script.

Verify that you have privileges to perform the intended power operation on the virtual machine.

To set optional power functions, install VMware Tools on the virtual machine.

Power off the virtual machine before editing the VMware Tools options.
