diff --git a/block/qcow2.c b/block/qcow2.c index d29547b..259edfd 100644 --- a/block/qcow2.c +++ b/block/qcow2.c @@ -1997,7 +1997,7 @@ static int qcow2_amend_options(BlockDriverState *bs, } if (new_size) { - ret = qcow2_truncate(bs, new_size); + ret = bdrv_truncate(bs, new_size); if (ret < 0) { return ret; }
When amending the size option for a qcow2 image, use bdrv_truncate instead of qcow2_truncate directly, since the latter will not adjust the total_sectors count in the BDS structure (whereas the former will).
