[Libguestfs] [PATCH v8 0/4] Import directly from OVA tar archive if possible
v8:
- split the big patch into several commits
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 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
are 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.
Tomáš Golembiovský (4):
mllib: add subdirectory function to common_utils
v2v: add function qemu_img_version to utils
v2v: add function find_file_in_tar to utils
v2v: ova: don't extract files from OVA if it's not needed

[Libguestfs] [PATCH v8 4/4] v2v: ova: don't extract files from OVA if it's not needed
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. Expected result of the
affected also has to depend on the QEMU used thus such tests will have
two *.expected files.

Re: [Libguestfs] [PATCH v8 0/4] Import directly from OVA tar archive if possible
I will push these in an hour or two after the slow tests have run. Note that I have made a few (only stylistic) changes to your commits, so if you `git pull --rebase' then you will see conflicts. Thanks for this important contribution to virt-v2v.

The error from v2v/test-v2v-i-ova.sh is: Original error from libvirt: internal error: missing parser implementation for JSON backing volume driver 'raw' [code=1 int1=-1] which I think is caused because libvirt doesn't understand a backing file with the format 'json:{"driver":"raw",...}'. Full log is attached. This is similar but not exactly the same as this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1134878 I have added a workaround in the test for now, but please look at whether this can be fixed more permanently.
