The GuestOSType can be specified when a VM is created and it can be modified
as part of the VM settings. This property is used to change certain default
parameters for the VM but only a few parameters like IOAPIC enabled. The
majority of parameters is initialized by the frontend when the VM is
created. The property can also be changed for an existing VM but in that
case no other setting is changed.

The available OS types can be listed with 'VBoxManage list ostypes'. They are
named like this: 'Ubuntu_64'.

The GuestOSTYpe provides a number of getter methods like recommendedRAM,
is64Bit and so on. 'VBoxManage list ostypes' shows a few of these properties,
the Qt GUI makes heavy use of these properties, see
