- Initialize VM after VM created - Some(true): VM will be created and initialized with the importers, which require external filesystem access - Some(false): VM will be created and initialized with the importers wihout external filesystem access - None: VM will be created but not initialized, so it is ready to be injected with modules. After injection, the `initialize_as_external` or `initialize_without_external` should be called, such that the VM will be ready to use. - Prevent double initialize VM by `initialized` flag
