This assumes the tar is uncompressed -- not a big issue, but I'd note that down in the API doc in the .mli. With the two small issues fixed, this LGTM. Thanks, -- Pino Toscano

IMHO this code should be where the current code is: Unix.access is currently done on the original file, while with your code it would be done only on the uncompressed file (either the uncompressed original, or the decompressed one). IMHO it is always better to do the existency check on our side, and assume that the uncompressed file will exist if zcat didn't fail. Thanks, -- Pino Toscano

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 leads to improvements in speed and puts much lower requirement on available disk space.

If you prefer qemu-utils.sh I will rename it. Wouldn't that be confusing? Maybe I could rename it to test-v2v-i-ova.ovf and test-v2v-i-ova.expected and then use it in both tests. Good point. Any specific reason for that? Here $d is specific to the test. It does not change between single runs of the test. -- Tomáš Golembiovský <tgolembi(a)redhat.com&gt;

As I see it, the main reason for removing path to vmdk was that the output is in temporary directory and the path varies between test runs. This is not the case here because $d is fixed in the test-*.sh file. Also, the output almost always depends on the test. I don't see a reason why the path should be treated somewhat differently here. If we remove the path it still won't allow us to reuse the *.expect file in two tests (not in this situation). Tomas -- Tomáš Golembiovský <tgolembi(a)redhat.com&gt;
