type: boolean
default: False
settings_password_file:
description: provide a file containing the settings password (equivalent to --settingspwfile)
network_info_path:

default: "/VirtualBox/GuestInfo/Net/0/V4/IP"
query:
description: create vars from virtualbox properties
type: dictionary
default: {}
compose:
description: create vars from jinja2 expressions, these are created AFTER the query block
