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. Signed-off-by: Tomáš Golembiovský <tgolembi@redhat.com>
