Adding also lago-devel. Eddy, isn't it the same issue I had on Fedora 26?

lago command taking 100% CPU
by Yaniv Kaul 30 Jul '17

30 Jul '17

When running o-s-t, and specifically when running add_secondary_storag, lago command is taking 100% CPU. I'm not sure where and why, and trying to narrow down the relevant threads did not yield a lot - it's not the Glance related functions, for example. I did try to make some changes to testlib.py, in an effort to reduce what I thought was a tight loop, but it made no effect (nevertheless, I think those are good changes): [ykaul@ykaul lago-ost-plugin]$ diff -u ovirtlago/testlib.py /usr/lib/python2.7/site-packages/ovirtlago/testlib.py --- ovirtlago/testlib.py 2017-07-28 11:15:31.506848944 +0300 +++ /usr/lib/python2.7/site-packages/ovirtlago/testlib.py 2017-07-28 09:29:19.403446285 +0300 @@ -209,7 +209,7 @@ return any(True for cls in cls_list if isinstance(obj, cls)) -def assert_equals_within(func, value, timeout, allowed_exceptions=None): +def assert_equals_within(func, value, timeout, allowed_exceptions=None, initial_wait=15): allowed_exceptions = allowed_exceptions or [] with utils.EggTimer(timeout) as timer: while not timer.elapsed(): @@ -219,12 +219,17 @@ return except Exception as exc: if _instance_of_any(exc, allowed_exceptions): + time.sleep(3) continue LOGGER.exception("Unhandled exception in %s", func) raise - time.sleep(3) + if initial_wait == 0: + time.sleep(3) + else: + time.sleep(initial_wait) + initial_wait = 0 try: raise AssertionError( '%s != %s after %s seconds' % (res, value, timeout) Any ideas how to debug this?

ssh to non-host vm
by Valentina Makarova 24 Jun '17

24 Jun '17

Hello! I try to use lago.ssh for ssh connection to non-host vm in ovirt-system-tests. And I have login/password (not root) for vm, but have not ssh-key. I try to use lago.ssh.get_ssh_client() to get connection but there is next code there: if ssh_key: client.connect( ip_addr, username=username, password=password, key_filename=ssh_key, timeout=ssh_timeout, ) else: client.connect( ip_addr, username='root', timeout=ssh_timeout, ) break But if I can't use key file, client should try to connect using login/password. And according this code I have to create empty file for this function and delete it after. (if ssh key != None but in is not existed file, client.connect ) Example is there: https://github.com/vmakarova/ovirt-system-tests/commit/855dbdf379730d55daf5… Is it a bug? Or is there some reasons for implementing this logic? Sincerely, Valentina Makarova

Lago v0.39 is out!
by Nadav Goldin 04 Jun '17

04 Jun '17

On behalf of the Lago team, I'm pleased to announce the new release of Lago and Lago-ost-plugin: Lago - v0.39 Lago-ost-plugin v0.41 This is the first release where we've separated Lago and lago-ost-plugin(aka ovirtlago) to different repositories, installation procedures should be the same. However, from now on the lago-ost-plugin will follow a different release cycle. It's repository can be found at [1], and docs at [2]. Note that 'lago-ost-plugin' requires Lago >= 0.39. What's new ========= Lago ------- 1. Improved Ansible inventory support. For more details see [3]. 2. Lago SDK - Allows to run most CLI operations directly from Python. See [4] for the docs, and [5] for an example. This is mostly standardization of the already provided SDK. 3. Debian network support in bootstrap stage. Lago Images ----------------- 3 New images were added, please help in verifying them: 1. fc25-base 2. debian8-base 3. ubuntu16.04-base There is a known issue with host name resolution after boot in debian, but it does not affect connectivity. Tests/CI ------------ 1. Moved to tox to setup the virtualenv during the tests: * `tox -e docs` - builds the docs. * `tox -e py27` - run unittests and linters. * `tox -c tox-sdk.ini -- --stage check_patch/check_merged` - to run the functional SDK tests for each stage(after you have installed lago - either in a nested virtualenv or from RPMs). 2. Added SDK functional tests: * Easy to run sanity check while developing, under tests/functional-sdk run: `pytest -s -vvv --setup-show --stage check_patch test_sdk_sanity.py` 3. Added multi-distro tests, which means prior to merging every Lago patch, we'll ensure the core images in templates.ovirt.org are functional with the new patch. 4. Added ansible functional tests on check-merged. For the full changelog see [6]. Upgrading ======== To upgrade using yum or dnf, simply run: ``` yum/dnf update lago ``` Resources ======== Lago Docs: http://lago.readthedocs.io/en/latest/ GitHub: https://github.com/lago-project/lago/ YUM Repository: http://resources.ovirt.org/repos/lago/stable/0.0/rpm/ OST Docs: http://ovirt-system-tests.readthedocs.io/en/latest/ As always, if you find any problems, please open an issue in the GitHub page.
