[PATCH v5 0/3] Import directly from OVA tar archive if possible
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 not run - 3/3: - using JSON module to generate JSON (as suggested by Pino) - all the other comments raised by Pino 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 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 in expect files v2: - rewritten the tar invocations, the output processing is now done in OcaML rather than with a shell code; it turned out to be easier and more readable than I have feared. - added QEMU version check - addressed Pino's comments - changed tests; the expected result is now based on the QEMU used during testing 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 of sparse files inside tar. But this can be done in a separate patch. As pointed out before I didn't find a way how to detect that by using the tar tool only and would probably require use of some external library.

The default is to keep the empty elements * count: specifies how many splits to perform; negative count (the default) means do as many splits as possible Added tests for nsplit.

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 puts much lower requirement on available disk space. Since the virt-v2v behaviour for OVA input now depends on QEMU version available this affects some of the tests. The affected tests will have two *.expect files and the expected result also has to depend on the QEMU used.
