[Libguestfs] [PATCH v2 1/2] v2v: ova: fix checking of the manifest file
The regular expression for parsing the manifest line was wrong. There is
a mandatory space between '=' and the hash.
Another problem was that only the first line of the manifest file was
actually processed.
Also added some debugging info and warning to catch problems with
parsing.
