module: vmware_guest_boot_manager
short_description: Manage boot options for the given virtual machine
description:
    - This module can be used to manage boot options for the given virtual machine.
version_added: 2.7
author:
    - Abhijeet Kasurde (@Akasurde) <akasurde@redhat.com>
notes:
    - Tested on vSphere 6.5
requirements:
    - "python >= 2.6"
    - PyVmomi
options:
   name:
     description:
     - Name of the VM to work with.
     - This is required if C(uuid) parameter is not supplied.
   uuid:
     description:
     - UUID of the instance to manage if known, this is VMware's BIOS UUID.
     - This is required if C(name) parameter is not supplied.
   boot_order:
     description:
     - List of the boot devices.
     default: []
   name_match:
     description:
     - If multiple virtual machines matching the name, use the first or last found.
     default: 'first'
     choices: ['first', 'last']
   boot_delay:
     description:
     - Delay in milliseconds before starting the boot sequence.
     default: 0
   enter_bios_setup:
     description:
     - If set to C(True), the virtual machine automatically enters BIOS setup the next time it boots.
     - The virtual machine resets this flag, so that the machine boots proceeds normally.
     type: 'bool'
     default: False
   boot_retry_enabled:
     description:
     - If set to C(True), the virtual machine that fails to boot, will try to boot again after C(boot_retry_delay) is expired.
     - If set to C(False), the virtual machine waits indefinitely for user intervention.
     type: 'bool'
     default: False
   boot_retry_delay:
     description:
     - Specify the time in milliseconds between virtual machine boot failure and subsequent attempt to boot again.
     - If set, will automatically set C(boot_retry_enabled) to C(True) as this parameter is required.
     default: 0
   boot_firmware:
     description:
     - Choose which firmware should be used to boot the virtual machine.
     choices: ["bios", "efi"]
