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.

Power Management options are not available on every guest operating system.

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.
  2. Click VM Options and expand Power Management.
  3. In the Standby response section, select the standby response of the virtual machine.
    • The Suspend the virtual machine option stops all processes, which saves resources, and copies the contents of the virtual machine's memory to the virtual machine's .vmss file. Writing the memory to the .vmss file is useful if you need to copy the file to help with a troubleshooting scenario.

    • The Put the guest operating system in standby mode and leave the virtual machine powered on option stops all processes, but leaves the virtual devices connected to the virtual machine.

  4. In the Wake on LAN section, select one or multiple virtual network adapters to which to apply the Wake on LAN option.
  5. Click OK to save your changes.
