The src_cache option (-T) specifies the cache mode for backing files.
9ae3a8
It applies both the image's old backing file as well as the new backing
9ae3a8
file:
9ae3a8
9ae3a8
  ret = bdrv_open(&bs_old_backing, backing_name, NULL, NULL, src_flags,
9ae3a8
                  old_backing_drv, &local_err);
9ae3a8
  if (ret) {
9ae3a8
      ...
9ae3a8
  }
9ae3a8
  if (out_baseimg[0]) {
9ae3a8
      bs_new_backing = bdrv_new("new_backing", &error_abort);
9ae3a8
      ret = bdrv_open(&bs_new_backing, out_baseimg, NULL, NULL, src_flags,
9ae3a8
                      new_backing_drv, &local_err);
9ae3a8
      if (ret) {
9ae3a8
          ...
9ae3a8
      }
9ae3a8
  }
9ae3a8
9ae3a8
The documentation only mentions the new backing file but it really
9ae3a8
applies to both.
