These two hunks don't look right. You probably want to amend the sed
command in _make_test_img().

This looks a bit hackish... Doesn't it completely ignore the requested
backing file name? I'm not sure if this is a good idea.
Can't you just create the raw image file and then use _optstr_add to add
the right -o image_file=... option? It should automatically get the
backing file right.
