vpc is not really a passthrough driver, even when using the fixed subformat (where host and guest offsets are equal). It should handle preallocation like all other drivers do, namely by returning DATA | RECURSE instead of RAW. There is no tangible difference but the fact that bdrv_is_allocated() no longer falls through to the protocol layer.
