Manage Power Management Settings for a Virtual Machine
If the guest operating system is placed on standby, the VM can either remain powered on or be
suspended. You can use the Power Management settings to control this behavior. Some desktop-based
guests, such as Windows 7, have standby enabled by default, so that the guest goes into standby after a
predetermined time.
The following conditions apply:
n
Power Management options are not available on every guest operating system.
n
Wake on LAN supports only Windows guest operating systems and is not available on Vlance NICs
or when a Flexible NIC is operating in Vlance mode. That is, the current VMware Tools are not
installed on the guest operating system.
n
Wake on LAN can resume virtual machines that are in an S1 sleep state only. It cannot resume
suspended, hibernated, or powered off virtual machines.
n
NICs that support Wake on LAN include Flexible (VMware Tools required), vmxnet, Enhanced
vmxnet, and vmxnet 3.
Note To avoid having the guest operating system go into standby mode unintentionally, verify the
settings before you deploy the virtual machine.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
