OST basic suite failing on el8 physical server
by Marcin Sobczyk 19 Feb '20

19 Feb '20

Hi all, I'm trying to run OST basic suite on CentOS 8 based physical server with lago running on py3. I'm currently stuck at 'verify_add_hosts' step. The engine continously tries to run: org.ovirt.engine.core.vdsbroker.vdsbroker.CollectVdsNetworkDataAfterInstallationVDSCommand but it ends up with a failure: 2020-02-18 05:29:01,386-05 DEBUG [org.ovirt.engine.core.dal.dbbroker.CustomSQLErrorCodeSQLExceptionTranslator] (EE-ManagedThreadFactory-engine-Thread-1) [39a236fd] Translating SQLException with SQL state '23505', error code '0', message [ERROR: duplicate key value violates unique constraint "name_server_pkey" Detail: Key (dns_resolver_configuration_id, address)=(98794c52-8364-4909-bbaf-a7ac16a1bf2a, 192.168.201.1) already exists. Here's part of my lago prefix status: [lago-basic-suite-master-host-0]: [NICs]: [eth0]: ip: 192.168.200.3 network: lago-basic-suite-master-net-management [eth1]: ip: 192.168.202.3 network: lago-basic-suite-master-net-storage [eth2]: ip: 192.168.201.2 network: lago-basic-suite-master-net-bonding [eth3]: ip: 192.168.201.3 network: lago-basic-suite-master-net-bonding distro: el8 [metadata]: deploy-scripts: $LAGO_PREFIX_PATH/scripts/_root_ovirt-system-tests_basic-suite-master_deploy-scripts_add_local_repo_no_ext_access.sh $LAGO_PREFIX_PATH/scripts/_root_ovirt-system-tests_basic-suite-master_deploy-scripts_setup_sar_stat.sh $LAGO_PREFIX_PATH/scripts/_root_ovirt-system-tests_basic-suite-master_deploy-scripts_setup_host_el7.sh $LAGO_PREFIX_PATH/scripts/_root_ovirt-system-tests_basic-suite-master_deploy-scripts_setup_1st_host_el7.sh root password: 123456 status: running [lago-basic-suite-master-host-1]: [NICs]: [eth0]: ip: 192.168.200.4 network: lago-basic-suite-master-net-management [eth1]: ip: 192.168.202.4 network: lago-basic-suite-master-net-storage [eth2]: ip: 192.168.201.4 network: lago-basic-suite-master-net-bonding [eth3]: ip: 192.168.201.5 network: lago-basic-suite-master-net-bonding So it seems the two bonding NICs indeed share the same dns resolver address - 192.168.201.1, but I suppose that's how it looks for all basic suite runs, right? Does anyone know what could be wrong in this setup and why the engine is complaining? Thanks, Marcin

do we even handle volume metadata in the engine?
by Fedor Gavrilov 19 Feb '20

19 Feb '20

Hi, It seems I was able to get my setup working for NFS storage, thanks for your advices! Now I'm afraid I am stuck again: what I need to do is to add validation for volume metadata to a certain command (to be exact, that VOLTYPE is LEAF). But I can't find examples of us dealing with this data in the engine part at all. I understand this is in the end executed by VDSM, but nevertheless - in what format are we even reading and writing volume metadata? Even class/method name would be helpful. Thanks, Fedor

What should I do to support DPDK in ovirt, any instruction?
by lifuqiong＠sunyainfo.com 17 Feb '20

17 Feb '20

Hi All, I found that there is rarely topics about supporting dpdk in ovirt 4.2 in Internet except https://blogs.ovirt.org/2018/07/upgraded-dpdk-support-in-ovirt/; and I can't get information such as whether or not should I install dpdk or ovn manual? And I will get an error when I execute such cmds: ansible-playbook ovirt.dpdk-setup/tasks/main.yml ansible-playbook oVirt.dpdk-setup I have some experience about ovn and dpdk, but I can't make ovirt supporting dpdk according the instruction in https://blogs.ovirt.org/2018/07/upgraded-dpdk-support-in-ovirt/; Is there anybody helping me? Thank you. Mark

somehow, no permission to run VM
by Fedor Gavrilov 15 Feb '20

15 Feb '20

Hi, Have you ever seen an error like this: 2020-02-15 20:05:16,246+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-27) [] EVENT_ID: VM_DOWN_ERROR(119), VM vm0 is down with error. Exit message: internal error: child reported (status=125): unable to open /rhev/data-center/mnt/banana:_nfsshare/45e51eaa-b608-40b1-9db6-6e6a1b3ed428/images/9d440b9a-b033-4209-898b-6667a4605281/ead2017a-a7fe-4408-b8d4-1670cb767474: Permission denied. in the engine logs? I'm getting it on my env (master branch) and can't figure out why. I login as admin, I have a perfectly working host and storage machines, on which I created this VM and its disk. Without any actions in between, I try to run it and get this. Storage domain and data center statuses are updated as you expect when you put the host to maintenance and back, so it seems this is the only thing wrong. Do you know what that might be? Thanks, Fedor

by scott.fitzgerald＠oracle.com 13 Feb '20

Hi, A VM Snapshot can be made using SnapshotBuilder builder = new SnapshotBuilder().vm(VM).name("Snap1").description("Test"); sysService.vmsService().vmService(VM.id()).snapshotsService().add().snapshot(builder).send(); It can be made with no memory by using a builder with persistMemorystate(false) How can one be made with no disk? .diskAttachments(emptyList) isnt working. TIA

please stop merging
by Dafna Ron 13 Feb '20

13 Feb '20

Hi all, Engine has been failing for a while and someone has also moved the broken package manually to the tested repo which broke all projects in cq. At this time, until we stabilise engine and get a new package into tested, all projects will continue failing cq and no new packages will be moved to the stable repo (tested). if you continue to merge, we not only risk adding more regression but it also makes it more difficult to debug and fix as there are a lot of changes in the queue waiting to be tested and very little resources to run it. Please stop merging on all projects until this is resolved. Thanks, Dafna

master CQ fails due to missing ovirt-host-deploy
by Dusan Fodor 13 Feb '20

13 Feb '20

Hello, master CQ is failing on initialize_engine due to missing ovirt-host-deploy dependency. [ INFO ] Checking for an update for Setup... [ ERROR ] Yum Cannot queue package ovirt-host-deploy: Package ovirt-host-deploy cannot be found I was under the impression that engine-setup should not require it anymore, but it seems the related patch [1] doesn't work as intended. Perhaps Marcin's comment there explains why? Can you please check this? Job example [2] Thanks [1] https://gerrit.ovirt.org/#/c/106797/ [2] https://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt-master_chang…
