[Libguestfs] [PATCH v6 3/3] v2v: ova: don't extract files from OVA if it's not needed
Tomáš Golembiovský

Mon Jan 30 21:43:16 UTC 2017
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.
