Set the Input and Output Device

  • input-device virtual-console

  • output-device virtual-console

When the virtual machine is reset, the named device becomes the initial firmware console input or output device. (If you want to temporarily change the input or output device, use the input or output commands.

  1. Specify the console input device.
    {0} ok setenv input-device device-specifier
  2. Specify the console output device.
    {0} ok setenv output-device device-specifier
