How to set up a (rh)el8 machine for running OST
Hi All, there are multiple pieces of information floating around on how to set up a machine for running OST. Some of them outdated (like dealing with el7), some of them more recent, but still a bit messy. Not long ago, in some email conversation, Milan presented an ansible playbook that provided the steps necessary to do that. We've picked up the playbook, tweaked it a bit, made a convenience shell script wrapper that runs it, and pushed that into OST project [1]. This script, along with the playbook, should be our single-source-of-truth, one-stop solution for the job. It's been tested by a couple of persons and proved to be able to set up everything on a bare (rh)el8 machine. If you encounter any problems with the script please either report it on the devel mailing list, directly to me, or simply file a patch. Let's keep it maintained. Regards, Marcin [1] https://gerrit.ovirt.org/#/c/111749/

So setup_for_ost.sh finished successfully (after more than an hour), but now I see conflicting documentation and comments about how to run test suites and how to cleanup after the run. The docs say: https://ovirt-system-tests.readthedocs.io/en/latest/general/running_tests/in... ./run_suite.sh basic-suite-4.0 But I see other undocumented ways in recent threads: run_tests Not sure which tests will run, and: run_tc basic-suite-master/test-scenarios/001_initialize_engine.py Which seems to run only one test module. This seems useful but for one module I found this undocumented command: python -B -m pytest -s -v -x --junit-xml=test.xml ${SUITE}/test-scenarios/name_test_pytest.py This looks most promising, assuming that I can use -k test_name or -m marker to select only some tests for quick feedback. However due to the way OST is built, mixing setup and test code, when later tests depend on earlier setup "tests" I don't see how this is going to work with current suites. What is the difference between the ways, and which one is the right way? My plan is to add a new storage suite that will run after some basic setup was done - engine, hosts, and storage are ready. Which tests scenarios are needed to reach this state? Do we have any documentation on how to add a new suite? or my only reference is the network suite? Nir

Another missing setup in setup_for_ost.sh?
Never encountered it myself, but I can also try enabling the 'libvirtd.socket' service in the playbook.
After adding myself to qemu group and starting libvirtd sockets lago_init seems to work.
time run_tests Not sure which tests will run, and:
run_tc basic-suite-master/test-scenarios/001_initialize_engine.py
Which seems to run only one test module. There's also 'run_tests', which runs all the tests for you.
This seems useful but for one module I found this undocumented command:
python -B -m pytest -s -v -x --junit-xml=test.xml ${SUITE}/test-scenarios/name_test_pytest.py
This looks most promising, assuming that I can use -k test_name or -m marker to select only some tests for quick feedback. However due to the way OST is built, mixing setup and test code, when later tests depend on earlier setup "tests" I don't see how this is going to work with current suites. That is true - the way OST works is that tests are dependent on previous tests. It's not nice, but this is how OST worked from the beginning - it's not feasible to set up a whole oVirt solution for each test case. Changing that requires a complete redesign of the project.
What is the difference between the ways, and which one is the right way?
'run_suite.sh' is used by CI and it brings all the legacy and the burden
My plan is to add a new storage suite that will run after some basic setup was done - engine, hosts, and storage are ready. Which tests scenarios are needed to reach this state?
Probably up until '002_bootstrap' finishes, but you have to find a point which satisfies you by yourself. If you think that there's too much stuff in
'run_tc' is still useful though. You can do 'run_tests' to run OST up to some point, i.e. force a failure with 'assert False' and work on your new test case with the whole setup hanging at some stage. There is no way currently to freeze and restore the the state of the environment though, so if you apply some intrusive changes you may need to rerun the suite from the beginning. possible (el7/py2/keeping all the suites happy etc.). 'lagofy.sh' OTOH was written by Michal recently and it's more lightweight and user friendly. There is no right way - work with the one that suits you better. that module, please make a suggestion to split it into separate ones.
Do we have any documentation on how to add a new suite? or my only reference is the network suite?
Unfortunately not, but feel free to reach me if you have any questions.

Another missing setup in setup_for_ost.sh?
Never encountered it myself, but I can also try enabling the 'libvirtd.socket' service in the playbook.
After adding myself to qemu group and starting libvirtd sockets lago_init seems to work.
time run_tests Not sure which tests will run, and:
run_tc basic-suite-master/test-scenarios/001_initialize_engine.py
Which seems to run only one test module. There's also 'run_tests', which runs all the tests for you.
This seems useful but for one module I found this undocumented command:
python -B -m pytest -s -v -x --junit-xml=test.xml ${SUITE}/test-scenarios/name_test_pytest.py
This looks most promising, assuming that I can use -k test_name or -m marker to select only some tests for quick feedback. However due to the way OST is built, mixing setup and test code, when later tests depend on earlier setup "tests" I don't see how this is going to work with current suites.
Perhaps what you want, some day, is for the individual tests to have make-style dependencies? So you'll issue just a single test, and OST will only run the bare minimum for running it. (Also, mind you, the integration team is still not perfect - we also have bugs - so "mixing setup and test code" is not a clear cut - setup code is also test code, as it runs code that we want to test, and which sometimes fails).
That is true - the way OST works is that tests are dependent on previous tests. It's not nice, but this is how OST worked from the beginning - it's not feasible to set up a whole oVirt solution for each test case. Changing that requires a complete redesign of the project.
'run_tc' is still useful though. You can do 'run_tests' to run OST up to some point, i.e. force a failure with 'assert False' and work on your new test case with the whole setup hanging at some stage. There is no way currently to freeze and restore the the state of the environment though, so if you apply some intrusive changes you may need to rerun the suite from the beginning.
There used to be 'lago snapshot', no? I think I even used it at some point.
What is the difference between the ways, and which one is the right way?
'run_suite.sh' is used by CI and it brings all the legacy and the burden possible (el7/py2/keeping all the suites happy etc.). 'lagofy.sh' OTOH was written by Michal recently and it's more lightweight and user friendly. There is no right way - work with the one that suits you better.
My plan is to add a new storage suite that will run after some basic setup was done - engine, hosts, and storage are ready. Which tests scenarios are needed to reach this state?
Probably up until '002_bootstrap' finishes, but you have to find a point which satisfies you by yourself. If you think that there's too much stuff in that module, please make a suggestion to split it into separate ones.
Do we have any documentation on how to add a new suite? or my only reference is the network suite?
Unfortunately not, but feel free to reach me if you have any questions.
Thanks! (Still in my TODO list to try this - hopefully soon). -- Didi

Hi All,
there are multiple pieces of information floating around on how to set up a machine for running OST. Some of them outdated (like dealing with el7), some of them more recent, but still a bit messy.
Not long ago, in some email conversation, Milan presented an ansible playbook that provided the steps necessary to do that. We've picked up the playbook, tweaked it a bit, made a convenience shell script wrapper that runs it, and pushed that into OST project [1].
This script, along with the playbook, should be our single-source-of-truth, one-stop solution for the job. It's been tested by a couple of persons and proved to be able to set up everything on a bare (rh)el8 machine. If you encounter any problems with the script please either report it on the devel mailing list, directly to me, or simply file a patch. Let's keep it maintained. Awesome, thanks! So setup_for_ost.sh finished successfully (after more than an hour), but now I see conflicting documentation and comments about how to run test suites and how to cleanup after the run.
The docs say: https://ovirt-system-tests.readthedocs.io/en/latest/general/running_tests/in...
./run_suite.sh basic-suite-4.0
But I see other undocumented ways in recent threads:
run_tests Trying the run_test option, from recent Mail:
. lagofy.sh lago_init /usr/share/ost-images/el8-engine-installed.qcow2 -k /usr/share/ost-images/el8_id_rsa This fails:

setup_for_ost.sh should handle this, no? It does: https://github.com/oVirt/ovirt-system-tests/blob/e1c1873d1e7de3f136e46b6355b... Maybe you didn't relog so the group inclusion would be effective? But I agree there should be a message printed to the user if relogging is necessary - I will write a patch for it.

Actually I was once thinking about introducing test dependencies in order to run independent tests in parallel and to speed up OST runs this way.

Exactly. I.e. I can see there's [1], but of course that will work only on py3. The dependency management is something we'd have to implement and maintain on our own probably. Then of course we'd be introducing the test repeatability problem, since ordering of things for different runs might be different, which in current state of OST is something I'd like to avoid.

It should be easy to have a switch between deterministic and non-deterministic ordering. Then one can use the fast, dynamic ordering for running tests more quickly and the suboptimal but deterministic ordering can be used for repeatability (on CI etc.). So this is not a real problem.

Why do you think it’s going to be significantly faster? I do not see much space for increasing it, at least not with the current set of tests. Actual tests that can run in parallel take cca 10 minutes. There’s initial install, backup/restore when you can’t run anything, storage operations ( if you try to parallelize them they only run slower(and fail)) You’re not going to gain much...

Yeah, I think I remember you did that during one of OST's hackathons.
When arranging some things manually, I could achieve a significant speedup. But the problem is, of course, how to make an automated dependency management and handle all the possible situations and corner cases. It would be quite a lot of work, I think.
Exactly. I.e. I can see there's [1], but of course that will work only on py3.
py3 is the least problem.
The dependency management is something we'd have to implement and maintain on our own probably.
Yes, this is the hard part.
Then of course we'd be introducing the test repeatability problem, since ordering of things for different runs might be different, which in current state of OST is something I'd like to avoid.
It should be easy to have a switch between deterministic and non-deterministic ordering. Then one can use the fast, dynamic ordering for running tests more quickly and the suboptimal but deterministic ordering can be used for repeatability (on CI etc.). So this is not a real problem.
Why do you think it’s going to be significantly faster? I do not see much space for increasing it, at least not with the current set of tests.
IIRC at the time I performed my experiments I could gain about 4 minutes from about 20-25 minutes of the non-repetitive part just by manually running a couple of things in parallel. And there were other obvious tasks that were waiting unnecessarily for other operations to finish. But this was a long time ago and things could indeed change significantly since then.
Actual tests that can run in parallel take cca 10 minutes. There’s initial install, backup/restore when you can’t run anything, storage operations ( if you try to parallelize them they only run slower(and fail)) You’re not going to gain much...
If all we can get is a couple of minutes at best from 30-60 minutes then it's irrelevant. At the same time, you provoke my curiosity about what OST is actually doing all the time. ;-)

So setup_for_ost.sh finished successfully (after more than an hour),
The long part is probably downloading OST images if you do it over a slow line. I don't think there is anything else there that takes a very long time to execute.
Would you consider presenting the flow of setting up the whole thing and running a test starting with a minimal CentOS 8 host? I would be happy to get it premiered on oVirt youtube channel and kept there for future references. This will enable more people willing to contribute to test their changes in local OST.

Hi All,
there are multiple pieces of information floating around on how to set up a machine for running OST. Some of them outdated (like dealing with el7), some of them more recent, but still a bit messy.
Not long ago, in some email conversation, Milan presented an ansible playbook that provided the steps necessary to do that. We've picked up the playbook, tweaked it a bit, made a convenience shell script wrapper that runs it, and pushed that into OST project [1].
This script, along with the playbook, should be our single-source-of-truth, one-stop solution for the job. It's been tested by a couple of persons and proved to be able to set up everything on a bare (rh)el8 machine. If you encounter any problems with the script please either report it on the devel mailing list, directly to me, or simply file a patch. Let's keep it maintained.
Regards, Marcin

I'd be very happy to, but I don't think it's the right time yet. While the setup process should be smooth now, we have two competing ways of running suites. One is the 'run_suite.sh' script, which is bloated and we're trying to move away from it somehow, and the other is 'lagofy.sh', which is much more modern and lightweight, but still needs some polishing. I would like to spend some more time on 'lagofy.sh' to make the user experience better and only then make the tutorial.
