2021-09-27qemu: Split machine_ppc.py acceptance testsDavid Gibson
machine_ppc.py contains tests for 3 different ppc based machine types. It is listed in MAINTAINERS along with the PPC TCG cpu code. That's not really accurate though, since it's really more about testing those machines than the CPUs. Therefore, split it up into separate files for the separate machine types, and list those along with their machine types in MAINTAINERS.

2021-09-27tests/Makefile: allow control over tags during check-acceptanceWillian Rampazzo
Although it is possible to run a specific test using the avocado command-line, a user may want to use a specific tag while running the ``make check-acceptance`` during the development or debugging. This allows using the AVOCADO_TAGS environment variable where the user takes total control of which tests should run based on the tags defined. This also makes the check-acceptance command flexible to restrict tests based on tags while running on CI. e.g.: AVOCADO_TAGS="foo bar baz" make check-acceptance Signed-off-by: Willian Rampazzo <willianr@redhat.com> Tested-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Reviewed-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210923161141.232208-2-willianr@redhat.com>

2021-09-27Acceptance Tests: add standard clean up at test tearDown()Cleber Rosa
The avocado.Test class, used as the basis of the avocado_qemu.Test class, performs a clean of temporary directories up as part of its own tearDown() implementation. But the avocado_qemu.Test class is currently missing the same clean up, as it implemented its own tearDown() method without resorting to the upper class behavior. This brings avocado_qemu.Test behavior in sync with the standard avocado.Test behavior and prevents temporary directories from cluttering the test results directory (unless instructed to do so with Avocado's "--keep-tmp" option).

2021-09-27tests/acceptance: Linux boot test for record/replayPavel Dovgalyuk
This patch adds a test for record/replay, which boots Linux image from the disk and interacts with the network. The idea and code of this test is borrowed from boot_linux.py This test includes only x86_64 platform. Other platforms and machines will be added later after testing and improving record/replay to completely support them. Each test consists of the following phases: - downloading the disk image - recording the execution - replaying the execution Replay does not validates the output, but waits until QEMU finishes the execution. This is reasonable, because QEMU usually hangs when replay goes wrong.

2021-09-15qcow2: handle_dependencies(): relax conflict detectionVladimir Sementsov-Ogievskiy
There is no conflict and no dependency if we have parallel writes to different subclusters of one cluster when the cluster itself is already allocated. So, relax extra dependency. Measure performance: First, prepare build/qemu-img-old and build/qemu-img-new images. cd scripts/simplebench ./img_bench_templater.py Paste the following to stdin of running script: qemu_img=../../build/qemu-img-{old|new} $qemu_img create -f qcow2 -o extended_l2=on /ssd/x.qcow2 1G $qemu_img bench -c 100000 -d 8 [-s 2K|-s 2K -o 512|-s $((1024*2+512))] \ -w -t none -n /ssd/x.qcow2 The result: All results are in seconds ------------------ --------- --------- old new -s 2K 6.7 ± 15% 6.2 ± 12% -7% -s 2K -o 512 13 ± 3% 11 ± 5% -16% -s $((1024*2+512)) 9.5 ± 4% 8.4 -12% ------------------ --------- --------- So small writes are more independent now and that helps to keep deeper io queue which improves performance. 271 iotest output becomes racy for three allocation in one cluster. Second and third writes may finish in different order. Second and third requests don't depend on each other any more. Still they both depend on first request anyway. Filter out second and third write offsets to cover both possible outputs.

2021-09-15block: bdrv_inactivate_recurse(): check for permissions and fix crashVladimir Sementsov-Ogievskiy
We must not inactivate child when parent has write permissions on it. Calling .bdrv_inactivate() doesn't help: actually only qcow2 has this handler and it is used to flush caches, not for permission manipulations. So, let's simply check cumulative parent permissions before inactivating the node. This commit fixes a crash when we do migration during backup: prior to the commit nothing prevents all nodes inactivation at migration finish and following backup write to the target crashes on assertion "assert(!(bs->open_flags & BDRV_O_INACTIVE));" in bdrv_co_write_req_prepare(). After the commit, we rely on the fact that copy-before-write filter keeps write permission on target node to be able to write to it. So inactivation fails and migration fails as expected. Corresponding test now passes, so, enable it.

2021-09-15tests: add migrate-during-backupVladimir Sementsov-Ogievskiy
Add a simple test which tries to run migration during backup. bdrv_inactivate_all() should fail. But due to bug (see next commit with fix) it doesn't, nodes are inactivated and continued backup crashes on assertion "assert(!(bs->open_flags & BDRV_O_INACTIVE));" in bdrv_co_write_req_prepare().

2021-09-15iotests/297: Cover tests/Hanna Reitz
297 so far does not check the named tests, which reside in the tests/ directory (i.e. full path tests/qemu-iotests/tests). Fix it. Thanks to the previous two commits, all named tests pass its scrutiny, so we do not have to add anything to SKIP_FILES.

2021-09-15mirror-top-perms: Fix AbnormalShutdown pathHanna Reitz
The AbnormalShutdown exception class is not in qemu.machine, but in qemu.machine.machine. (qemu.machine.AbnormalShutdown was enough for Python to find it in order to run this test, but pylint complains about it.)

2021-09-15migrate-bitmaps-test: Fix pylint warningsHanna Reitz
There are a couple of things pylint takes issue with: - The "time" import is unused - The import order (iotests should come last) - get_bitmap_hash() doesn't use @self and so should be a function - Semicolons at the end of some lines - Parentheses after "if" - Some lines are too long (80 characters instead of 79) - inject_test_case()'s @name parameter shadows a top-level @name variable - "lambda self: mc(self)" were equivalent to just "mc", but in inject_test_case(), it is not equivalent, so add a comment and disable the warning locally - Always put two empty lines after a function - f'exec: cat > /dev/null' does not need to be an f-string Fix them.

2021-09-15migrate-bitmaps-postcopy-test: Fix pylint warningsHanna Reitz
pylint complains that discards1_sha256 and all_discards_sha256 are first set in non-__init__ methods. These variables are not really class-variables anyway, so let them instead be returned by start_postcopy(), thus silencing pylint.
