Enable power management on Host
by scott.fitzgerald＠oracle.com 30 Sep '19

30 Sep '19

Hi, I am currently trying to enable Power Management on a host. I have created a PowerManagementBuilder object, with an AgentBuilder. However, I am getting the error .Error: Fault reason is "Operation Failed". Fault detail is "[Cannot edit Host. Power Management is enabled for Host but no Agent type selected.]". HTTP response code is "400". HTTP response message is "Bad Request" sysService.hostsService().hostService(HostUtils.getHostObjectFromName(sysService, vdsmHostName).id()).update().host(host().powerManagement(powerManagementBuilder.build())).send(); Am I missing a step? Or could someone post the snippet of building an Agent and PowerManagement object so I can check against what I'm doing (below). TIA PowerManagementBuilder powerManagementBuilder = new PowerManagementBuilder(); AgentBuilder agentBuilder = new AgentBuilder(); agentBuilder.address(address); agentBuilder.concurrent(true); agentBuilder.host(host); agentBuilder.id("newAgent"); agentBuilder.name("newAgent"); agentBuilder.username("test"); agentBuilder.type("apc"); agentBuilder.port(22); agentBuilder.password("xxx"); sysService.hostsService().hostService(host.update().host(host().agents(agentBuilder.build())).send(); powerManagementBuilder.address(address); powerManagementBuilder.agents(agentBuilder.build()); powerManagementBuilder.automaticPmEnabled(true); powerManagementBuilder.enabled(true); powerManagementBuilder.password("xxx"); powerManagementBuilder.type("apc"); powerManagementBuilder.username("test"); sysService.hostsService().hostService(host).update().host(host().powerManagement(powerManagementBuilder.build())).send();

OST: Failure in next_run_unplug_cpu
by Milan Zamazal 30 Sep '19

30 Sep '19

Hi, I experienced the following OST failure on Friday: https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-test… It failed in next_run_unplug_cpu, due to the fact that the VM hadn't switched to UP status after reboot. I could run OST on the same patch successfully (besides a usual add_master_storage_domain failure) afterwards, so it looks like a random failure. I can see numerous guest agent timeouts after the VM start but other than that I couldn't find any error. The VM apparently has kept reporting POWERING_UP status, I can't see why it didn't switch to UP status eventually. Thanks, Milan

build-artifacts job stuck on s390x - cannot run OST
by Nir Soffer 29 Sep '19

29 Sep '19

Since Friday build-artifacts on s390x get stuck again, so we cannot run OST. This is not a new issue, we have issues on s390x every few weeks. I posted this patch to disable this job: https://gerrit.ovirt.org/c/97851 We can enable the job when we have a reliable build slave again. Here are some failed jobs: - http://jenkins.ovirt.org/job/standard-manual-runner/757/ - http://jenkins.ovirt.org/job/standard-manual-runner/758/ - http://jenkins.ovirt.org/job/standard-manual-runner/759/ - http://jenkins.ovirt.org/job/standard-manual-runner/762/ - http://jenkins.ovirt.org/job/standard-manual-runner/763/ - http://jenkins.ovirt.org/job/standard-manual-runner/764/ Nir

Hi, This mail is to provide the current status of CQ and allow people to review status before and after the weekend. Please refer to below colour map for further information on the meaning of the colours. *CQ-4.3*: GREEN (#3) Last failure was on 27-09 for v2v-conversion-host. Job was marked as failed because its on merge job (ghpush) tries to queue change in now non-existing 4.2 CQ. *CQ-Master:* RED (#1) Last failure was on 27-09 was for ovirt-engine on adding storage domain. This is a random failure described in thread "random failures for add_master_storage_domain", awaiting its fix. Another issue detected is in initialize_engine test, mail was sent to investigate it. Current running jobs for 4.3 [1] and master [2] can be found here: [1] https://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt -4.3_change-queue-tester/ [2] http://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt -master_change-queue-tester/ Have a nice week!

Error when removing unmanaged networks after Removal of Data Center
by scott.fitzgerald＠oracle.com 27 Sep '19

27 Sep '19

Hi, Test case is to remove a data center, validating the attached domain goes to an UNATTACHED state. This works, however, the code I am using to clean the system down after the test cannot remove the Default Management Network from the host as part of the cleanup of unmanaged networks. It returns a 400 error when running netService.unmanagedNetworkService(network.id()) .remove() .send(); For the Default Network, which is left on the host as a result of tearing down the Data Center, but the Host still being alive. If I tear down the host without removing the unmanaged network I get a successful test, but later use of the host results in errors relating to the same unmanaged network. In the engine log I see the following Exception: java.lang.IllegalStateException: There isn't unique management network for cluster <name> among networks (). Any help is much appreciated.

Re: [ovirt-users] oVirt and CentOS Stream

Most of the time, these changes are iterative: progressive additions of features to projects like oVirt. Sometimes those changes are small, and sometimes not.

Patch Gating summary + FAQ
by Ehud Yonasi 27 Sep '19

27 Sep '19

Hey everyone, Following the presentation we did last week [1] <https://bluejeans.com/s/zAjyX/>, I wanted to summarize the new patch gating workflow that will be pushed to oVirt soon and will impact all the developers. Summary: The purpose of the new workflow is to verify patches earlier ( shift left ) before they are merged and provide much faster feedback for developers if their patch fails OST. 1. Feedback from OST will now be posted directly to Gerrit instead of requiring human intervention from the infra team to notify developers We expect developers to check why their patch is not passing the gate (OST), debug it, find the root cause and fix it before merging the patch. 1. Any concerns regarding the stability of OST should be communicated and addressed ASAP. The status today is that if OST fails post-merge gating packages are not pushed to tested and QE doesn’t get to test them. The change with pre-merge gating is that patches won’t be merged if OST fails, so if there are any fragile or flaky tests they should be examined by their maintainers and fixed, skipped or removed by the maintainers. 1. FYI, we are not removing the Merge button at this point, so maintainers will still be able to merge patches that they believe 100% is not breaking the build and failing OST tests. Please note that merging patches that break OST will cause it to start failing for all other patches, we urge you to avoid trying to bypass it if at all possible. In the following section, I will explain more on Patch Gating, how to onboard it, etc. FAQ on oVirt’s Gating System and how to onboard your project on it: Q. What is Patch Gating? A. It is triggered pre-merge on patches and running OST as the gate system tests, unlike today where we have post-merge OST that runs the patches after the projects are merged. This means developers get early feedback on their patches if it is passing OST. Q. What causes the gating process to start? A. Once a patch is verified, passed CI and has Code-Review +2 labels, the gating process will be started. You will receive a message in the patch Q. How does it report results to my patches? A. A comment will be posted in your patch with the job URL failure. Q. How will my patch get merged? A. If the patch has passed the gating (OST), Zuul (The new CI system for patch gating) will merge the patch automatically. Q. How do I onboard my project? A. 1. Open a JIRA ticket or mail to infra-support(a)ovirt.org 2. Creating a file named 'zuul.yaml' under your project root OR `zuul.d/zuul.yaml` and fill with the following content: - project: templates: - ost-gated-project Q. My projects run on STDCI V1, is that ok? A. No, the patch gating logic runs on STDCI V2 only! meaning that you will have to shift your project to V2. If you need help regarding the transition to V2 you can open a JIRA[2] <https://ovirt-jira.atlassian.net>ticket or mail to infra-support(a)ovirt.org and visit the docs [3] <https://ovirt-infra-docs.readthedocs.io/en/latest/>. Q. What if I want to merge the patch regardless of OST results? A. If you are a maintainer of the project, you can still merge it. we are not removing the merge button option. But, merging when failing OST can break your project so merging on failure is unadvertised. Q. What if my patch failing because of dependency on different project patch? A. Patch Gating (Zuul) has a mechanism for cross-project dependency! All you need to do is to add to the commit message the patch URL you are dependent on: Depends-On: https://gerrit.ovirt.org/patch_number And they will be tested together. Note: you can have multiple dependencies. Q. How do I debug OST? A. There are various ways of looking in the logs and output for the errors: 1. Blue Ocean view, <https://jenkins.ovirt.org/blue/organizations/jenkins/ovirt-system-tests_gat…> you can see the jobs that were run inside the gate and find the suites which failed. 2. ci_build_summary view, An internal tool to view the threads and redirect to the specific logs/artifacts. 3. Test results analyzer, available if the tests were run. you can view the failed tests and their output and OST maintainers and your team leads should be able to assist. 4. For further learning on how to debug OST please visit the OST FAQ <https://drive.google.com/open?id=1Sohq7bdgZS341gs5-lvB9lyS0GXawqaIvuUziOWwo…> . Q. Will the current infrastructure be able to support all the patches? A. The CI team has made tremendous work in utilizing the infrastructure. The OST gating will run inside OpenShift pods unlike before as bare metals and we can gain from that right now approximately 50 pods in parallel to run simultaneously and we will review adding more if the need arises. Q. When I have multiple patches, in which order will they be tested by the gating system? A. The patches will be tested as the flow they will be merged. The gating system knows how to simulate patches post-merge. Q. What do I do if I think OST failed because of an infra issue and not my patch? A. You can contact the CI team by sending mail to infra-support(a)ovirt.org and explain your concerns + sending the patch URL. Q. Will check-merged scripts be used by the gating system? A. No, they will be used in the current workflow with OST post-merge gating system called Change-Queue. Q. Can I add my own tests to the gating system? A. The gating system is running OST tests, so if it’s a test that should be included in the OST, then yes. Q. What will happen to the old change-queue system now that we have gating? A. At this time, the change-queue system will stay and gate post-merge jobs until all of oVirt projects will onboard to patch gating. We might consider using the change-queue for further coverage of tests in the future. Q. How can I re-trigger a failed patch to the gate again? A. There are 2 options to retrigger: - If the case is to fix your patch, just uploaded a new patchset and turn the Code-Review, Verified and CI labels again. - If you want to re-trigger the same patchset again just write a comment in Gerrit: ‘ci emulate-gate please’ Q. I usually write a series of related patches that should be merged together, can the Gating system test all of them in a single test? A. No, they will be tested in parallel as the number of patches in the series. This is why we’ve increased our capacity to run OST for this case. Architectural design document [4] <https://drive.google.com/open?id=1qV_iNJL6jHARlti7zpnRZRfQM_Q9Z-w8ONvcKEmaA…> would provide you the understanding of the patch gating process with the new services we will be using.

ovirt-engine on master compiles and runs on Java-11
by Roy Golan 27 Sep '19

27 Sep '19

Hi all, ovirt-engine project reached a nice milestone, compiling and running on Java-11 📣 The move itself needed care to see nothing breaks and with the help of OST it remaind like unbroken, but the move was mostly painless and didn't require changes to real business logic code. It was mainly to deal with 2 things, working with modules and lack of support from GWT. Modular JDK (project jigsaw) landed in java-9 is more relevant to the delivery of the sofware rather to the development of it. Specifically now you can ship your software only with a subset of the jdk, or produce your jar as a module so it can expose or hide internal with real enforcment(even no reflection). The relevant part to the change here is that java doesn't provide EE code in the jdk, specifically java.xml, java.annotation, javax.activation [1] GWT and specifically the gwt compiler doesn't recognize java syntax beyond 8, and efforts of the community to support don't look promising. Luckily since it is strictly compile-time only concern the invocation of the gwt compiler, which is invoked by maven, is instructed to use java-8 javac. This means the frontend artifacts are remain uneffected by this change. Morning comes, I want to rebase and compile the project! This should not be huge change, and is document here [2]: - install java-11-openjdk-devel - make java-11 binaries available on your path *before java-8 *(use your favorite method I use alternatives) - install maven >= 3.5.0 Please report any problem here and also if the README [2] is not helping enough please help improve it! P.S - Obviously it is strongly encouraged to get familiar with what java 9, 10, and 11 brought in and start make use of it. If you think you have code you want to contribute to master, but is going to be backported to 4.3 bare in mind the difference in java version. Thanks, Roy [1] covered in the git log https://gerrit.ovirt.org/#/c/98623/ [2] https://github.com/oVirt/ovirt-engine/blob/master/README.adoc#note-on-java-…

Setting reason for VM shutdown
by scott.fitzgerald＠oracle.com 26 Sep '19

26 Sep '19

Hi all, I have a test case as follows: Enable "require reason for vm maintenance" on Cluster Shutdown vm Ensure reason is saved A similar case for hosts is achieved by the following hostsService .hostService(host.id()) .deactivate() .reason(reason) .send(); But the shutdown option for vms does not have a reason option. How can I set the reason for shutdown of a VM through the SDK? TIA

I am trying to verify whether a Networks VM Network checkbox is checked using the SDK, but I cannot see any methods or variable with a similar name. Is it possible to find out if a network has a VM Network Role using the SDK?
