similar to: [PATCH 2/2] v2v: ova: support SHA256 hashes in manifest

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.

This series fixes and enhances parsing of the OVA manifest file. The changes are: - Added mandatory space to the regexp - Process all lines in the file, not just one - Warn on improperly formated lines - Support SHA256 hashes v1 -> v2: rebased on to master to make use of the Checksums module Tomáš Golembiovský (2): v2v: ova: fix checking of the manifest file v2v: ova: support SHA256

We don't have to always extract all files from the OVA archive. The OVA, as defined in the standard, is plain tar. We can work directly over the tar archive if we use correct 'offset' and 'size' options when defining the backing file for QEMU. This leads to improvements in speed and puts much lower requirement on available disk space. Signed-off-by: Tomáš Golembiovský

Can you please provide an example of manifest file with more than one line? A real-life

This series is related to the problem of inefficient import of OVA files. The needed enhancements of QEMU were merged into the codebase and should be available in QEMU 2.8. From there we can use 'size' and 'offset' options in raw driver to tell QEMU to use only subset of a file as an image. The patch set is more or less complete. The only outstanding issue is the missing detection

v3: Addressed Pino's comments, namely: - input_ova.ml - untar takes list of paths - renamed untar_partial to untar_metadata - replaced uggly regex with nsplit - tests - test changes are part of the main commit - renamed test-data/guestfs-hashsums.sh to test-data/test-utils.sh - renamed qemu_version to qemu_is_version and moved it to test-data/test-utils.sh - normalize paths
