module: vcenter_vm_hardware_boot_device
short_description: Sets the virtual devices that will be used to boot the virtual
  machine
description: Sets the virtual devices that will be used to boot the virtual machine.  The
  virtual machine will check the devices in order, attempting to boot from each, until
  the virtual machine boots successfully.  If the {@term list} is empty, the virtual
  machine will use a default boot sequence. There should be no more than one instance
  of {@link Entry} for a given device type except {@link Device.Type#ETHERNET} in
  the {@term list}.
options:
  devices:
