iotests: Add test for relative backing file names Sometimes, qemu does not have a filename to work with, so it does not know which directory to use for a backing file specified by a relative filename. Add a test which tests that qemu exits with an appropriate error message. Additionally, add a test for qemu-img create with a backing filename relative to the backed image's base directory while omitting the image size.

QA output created by 110
=== Reconstructable filename ===
Formatting 'TEST_DIR/t.IMGFMT.base', fmt=IMGFMT size=67108864
opts: produce valid command line in qemu_opts_print This will let us print options in a format that the user would actually write it on the command line (foo=bar,baz=asd,etc=def), without prepending a spurious comma at the beginning of the list, or quoting values unnecessarily. This patch provides the following changes: * write and id=, if the option has an id * do not print separator before the first element * do not quote string arguments * properly escape commas (,) for QEMU Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

=== Non-reconstructable filename ===
block/qapi: allow best-effort query For more complex BDS trees that can be created under normal circumstances, we lose the ability to issue query commands because of our inability to re-construct the absolute filename. Instead, omit this field when it is a problem and present as much information as we can. This will change the expected output in iotest 110, where we will now see a json filename and the lack of an absolute filename instead of an error.

block: Use bdrv_dirname() for relative filenames bdrv_get_full_backing_filename_from_filename() breaks down when it comes to JSON filenames. Using bdrv_dirname() as the basis is better because since we have BDS, we can descend through the BDS tree to the protocol layer, which gives us a greater probability of finding a non-JSON name; also, bdrv_dirname() is more correct as it allows block drivers to override the generation of that directory name in a protocol-specific way. We still need to keep bdrv_get_full_backing_filename_from_filename(), though, because it has valid callers which need it during image creation when no BDS is available yet. This makes a test case in qemu-iotest 110, which was supposed to fail, work. That is actually good, but we need to change the reference output (and the comment in 110) accordingly.

iotests: Add quorum case to test 110 Test 110 tests relative backing filenames for complex BDS trees. Now that the originally supposedly failing test passes, let us add a new failing test: Quorum can never work automatically (without detecting whether all child nodes have the same base directory, but that would be rather inconsistent behavior).
