[VDSM] Started getting virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired
by Edward Haas 11 Jan '24

11 Jan '24

Hi, I have a VM which acts as an oVirt host with VDSM installed. I use it for testing without connecting it to Engine. Recently VDSM fails to come up and I see this error: Sep 26 17:58:18 localhost libvirtd: 2018-09-26 14:58:18.978+0000: 12176: error : virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired Any hint on how to generate or fetch a new certificate without the help of Engine? Thanks, Edy.

by Geschwentner, Patrick 02 Apr '21

02 Apr '21

Dear Ladies and Gentlemen! I am currently working with the java-sdk and I encountered a problem. If I would like to retrieve the disk details, I get the following error: Disk currDisk = ovirtConnection.followLink(diskAttachment.disk()); The Error is occurring in this line: [cid:image001.png@01D44537.AF127FD0] The getResponst looks quiet ok. (I inspected: [cid:image002.png@01D44537.AF127FD0] and it looks ok). Error: wrong number of arguments The code is quiet similar to what you published on github (https://github.com/oVirt/ovirt-engine-sdk-java/blob/master/sdk/src/test/jav… ). Can you confirm the defect? Best regards Patrick

OST's basic suite UI sanity tests optimization
by Marcin Sobczyk 07 Aug '19

07 Aug '19

Hi, _TL; DR_ Let's cut the running time of '008_basic_ui_sanity.py' by more than 3 minutes by sacrificing Firefox and Chrome screenshots in favor of Chromium. During the OST hackathon in Brno this year, I saw an opportunity to optimize basic UI sanity tests from basic suite. The way we currently run them, is by setting up a Selenium grid using 3 docker containers, with a dedicated network... that's insanity! (pun intended). Let's a look at the running time of '008_basic_ui_sanity.py' scenario (https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-test…) 01:31:50 @ Run test: 008_basic_ui_sanity.py: 01:31:50 nose.config: INFO: Ignoring files matching ['^\\.', '^_', '^setup\\.py$'] 01:31:50 # init: 01:31:50 # init: Success (in 0:00:00) 01:31:50 # start_grid: 01:34:05 # start_grid: Success (in 0:02:15) 01:34:05 # initialize_chrome: 01:34:18 # initialize_chrome: Success (in 0:00:13) 01:34:18 # login: 01:34:27 # login: Success (in 0:00:08) 01:34:27 # left_nav: 01:34:45 # left_nav: Success (in 0:00:18) 01:34:45 # close_driver: 01:34:46 # close_driver: Success (in 0:00:00) 01:34:46 # initialize_firefox: 01:35:02 # initialize_firefox: Success (in 0:00:16) 01:35:02 # login: 01:35:11 # login: Success (in 0:00:08) 01:35:11 # left_nav: 01:35:29 # left_nav: Success (in 0:00:18) 01:35:29 # cleanup: 01:35:36 # cleanup: Success (in 0:00:06) 01:35:36 # Results located at /dev/shm/ost/deployment-basic-suite-master/008_basic_ui_sanity.py.junit.xml 01:35:36 @ Run test: 008_basic_ui_sanity.py: Success (in 0:03:45) Starting the Selenium grid takes 2:15 out of 3:35 of total running time! I've investigated a lot of approaches and came up with something like this: * install 'chromium-headless' package on engine VM * download 'chromedriver' and 'selenium hub' jar and deploy them in '/var/opt/' on engine's VM * run 'selenium.jar' on engine VM from '008_basic_ui_sanity.py' by using Lago's ssh * connect to the Selenium instance running on the engine in '008_basic_ui_sanity.py' * make screenshots This series of patches represent the changes: https://gerrit.ovirt.org/#/q/topic:selenium-on-engine+(status:open+OR+statu…. This is the new running time (https://jenkins.ovirt.org/view/oVirt system tests/job/ovirt-system-tests_manual/4195/): 20:13:26 @ Run test: 008_basic_ui_sanity.py: 20:13:26 nose.config: INFO: Ignoring files matching ['^\\.', '^_', '^setup\\.py$'] 20:13:26 # init: 20:13:26 # init: Success (in 0:00:00) 20:13:26 # make_screenshots: 20:13:27 * Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fdb6004f8d0>: Failed to establish a new connection: [Errno 111] Connection refused',)': /wd/hub 20:13:27 * Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fdb6004fa10>: Failed to establish a new connection: [Errno 111] Connection refused',)': /wd/hub 20:13:27 * Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fdb6004fb50>: Failed to establish a new connection: [Errno 111] Connection refused',)': /wd/hub 20:13:28 * Redirecting http://192.168.201.4:4444/wd/hub -> http://192.168.201.4:4444/wd/hub/static/resource/hub.html 20:14:02 # make_screenshots: Success (in 0:00:35) 20:14:02 # Results located at /dev/shm/ost/deployment-basic-suite-master/008_basic_ui_sanity.py.junit.xml 20:14:02 @ Run test: 008_basic_ui_sanity.py: Success (in 0:00:35) (The 'NewConnectionErrors' is waiting for Selenium hub to be up and running, I can silence these later). And the screenshots are here: https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-test… _The pros:_ * we cut the running time by more than 3 minutes _The cons:_ * we don't get Firefox or Chrome screenshots - we get Chromium screenshots (although AFAIK, QE has much more Selenium tests which cover both Firefox and Chrome) * we polute the engine VM with 'chromium-headless' package and deps (in total: 'chromium-headless', 'chromium-common', 'flac-libs' and 'minizip'), although we can remove these after the tests _Some design choices explained:_ Q: Why engine VM? A: Because the engine VM already has 'X11' libs. We could install 'chromium-headless' (and even other browsers) on our Jenkins executors, but that would mess them up a lot. Q: Why Chromium? A: Because it has a separate 'headless' package. Q: Why not use 'chromedriver' RPM in favor of https://chromedriver.storage.googleapis.com Chromedriver builds? A: Because the RPM version pulls a lot of extra dependencies even on the engine VM ('gtk3', 'cairo' etc.). Builds from the URL are the offical Google Chromedriver builds, they contain a single binary, and they work for us. _What still needs to be polished with the patches:_ * Currently 'setup_engine_selenium.sh' script downloads each time 'selenium.jar' and 'chromedriver.zip' (even with these downloads we get much faster set-up times) - we should bake these into the engine VM image template. * 'selenium_hub_running' function in 'selenium_on_engine.py' is hackish - an ability to run an ssh command with a context manager (and auto-terminate on it exits) should be part of Lago. Can be refactored. Questions, comments, reviews are welcome. Regards, Marcin

Successful 'vdsm-client Host getStats' call on py3
by Marcin Sobczyk 10 Jul '19

10 Jul '19

Hi, I'm currently working on making yajsonrpc/stomp implementation py3-compatible so we can have basic communication with vdsm running on py3. Today for the first time I was able to run vdsm [1] with py3 on fc29 and do a successful 'vdsm-client Host getStats' call. Since these patches are needed for other teams to continue with their work on py3, I'd kindly request those of you who are interested to review them: https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… https://gerrit.ovirt.org/#/q/status:open+project:vdsm+branch:master+topic:p… [1] with minor tweak to 'storage.hsm' module

Proposing Andrej Krejcir as a maintainer of engine core
by Arik Hadas 02 Jul '19

02 Jul '19

Dear engine-core maintainers, I'd like to propose Andrej Krejcir as a maintainer of oVirt engine backend. Since Jul 2015, Andrej has been contributing to ovirt-engine, mostly in SLA areas (scheduling, quota, etc) and recently being more and more involved also in the VIRT areas. This results in ~200 patches to engine master alone. Personally, I reviewed some of Andrej's contributions and noticed reviews made by Andrej to others. I sincerely believe Andrej would be a good addition to the maintainers' group. Thanks in advance for your response!

Storage test case needs to be fixed: 002_bootstrap.resize_and_refresh_storage_domain
by Dafna Ron 02 Jul '19

02 Jul '19

Hi Tal, I am seeing random failures for test 002_bootstrap.resize_and_refresh_storage_domain It looks like this is a timing issue since by the time we print out the error we actually see the resize succeeded. see example below: http://jenkins.ovirt.org/job/ovirt-master_change-queue-tester/14185/testRep… Can you please assign someone from the storage team to fix this test? Thanks, Dafna

Getting "Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured" after upgrading RHV 4.2 to 4.3
by Lynn Dixon 30 Jun '19

30 Jun '19

I attempted to upgrade a hosted engine environment that was running RHV 4.2 to RHV 4.3 and everything appeared to have worked fine. Except when I login to the webui, I get the error in the dashboard that "Could not fetch dashboard data...." I see the dwhd service is running, and I noticed that there was a postgresql upgrade in the engine-setup, but I did not see any errors or oddness during the upgrade process. Is there something I am missing? *Lynn Dixon* | Red Hat Certified Architect #100-006-188 *Sr. Cloud Consultant* | Cloud Management Practice Google Voice: 423-618-1414 Cell/Text: 423-774-3188 Click here to view my Certification Portfolio <http://red.ht/1XMX2Mi>

USB on host support?
by Hetz Ben Hamo 29 Jun '19

29 Jun '19

Hi, I'm in communication with a company that thinks about RHV. One of the requirements is USB host support (which will be on the nodes, not on the desktops). I haven't found any way to connect USB to a VM other then through SPICE, but this method won't help as these dongles won't be on desktops. Is this in the road map of oVirt? Thanks
