v1 -> v2: - Use 'qemu-img info' which avoids one of the temporary files (thanks Tomáš). - Add a unit test. Unfortunately when I run 'make -C v2v check' I don't think this code is being run at all, so there may be something else going on here which I don't understand. Rich.

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

v7: - rebased because patch 1/3 has been pushed - changes to nsplit have been dropped (2/3) - addressed Richard's comments, notably the subfolder function was moved to mllib and renamed to subdirectory v6: - just rebase v5: - rebase, patches 1,3,5 were merged - 1/3: we still need to discuss whether to detect compressed discs - 2/3: - renamed argument noempty to keep_empty - tests were

v4: - rebase to more recent master - 1/6: using just "quote" instead of "Filename.quote" - 2/6: reformated block of code according to Richards suggestion - 4/6: added tests for nsplit 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
