I think this would need a libringbuffer as nova would need to read the same file in get_console_output. When I first looked at this in September, I could not find such a thing, or any accepted on-disk format. The python code in my patch could be a good starting point, but there a couple of things I think needed to be added. First, a magic to identify the file; and second, some kind of mutex or locking mechanism to cover the head and tail pointers and prevent slow readers from reading past the join.
