From fbc8e1b7e49dee9b137c1037dc72d8e6fd4aba3d Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Thu, 25 Jul 2019 17:55:12 +0200 Subject: vpc: Do not return RAW from block_status 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.
