VM rebooted during OST test_hotplug_cpu
by Yedidyah Bar David 01 Jul '20

01 Jul '20

Hi all, I am trying to verify fixes for ovirt-engine-rename, specifically for OVN. Engine top patch is [1], OST patch [2]. Ran the manual job on these [3]. In previous patches, OST failed in earlier tests. Now, it passed these tests, so I hope that my patches are enough for what I am trying to do. However, [3] did fail later, during test_hotplug_cpu - it set the number of CPUs, then tried to connect to the VM, and timed out. The logs imply that right after it changed the number of CPUs, the VM was rebooted, apparently by libvirtd. Relevant log snippets: vdsm [4]: 2020-06-29 10:21:10,889-0400 DEBUG (jsonrpc/1) [virt.vm] (vmId='7474280d-4501-4355-9425-63898757682b') Setting number of cpus to : 2 (vm:3089) 2020-06-29 10:21:10,952-0400 INFO (jsonrpc/1) [api.virt] FINISH setNumberOfCpus return={'status': {'code': 0, 'message': 'Done'}, 'vmList': {}} from=::ffff:192.168.201.4,54576, flow_id=7f9503ed, vmId=7474280d-4501-4355-9425-63898757682b (api:54) 2020-06-29 10:21:11,111-0400 DEBUG (periodic/0) [virt.sampling.VMBulkstatsMonitor] sampled timestamp 2925.602824355 elapsed 0.160 acquired True domains all (sampling:451) 2020-06-29 10:21:11,430-0400 DEBUG (jsonrpc/1) [jsonrpc.JsonRpcServer] Return 'VM.setNumberOfCpus' in bridge with {} (__init__:356) 2020-06-29 10:21:11,432-0400 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call VM.setNumberOfCpus succeeded in 0.56 seconds (__init__:312) 2020-06-29 10:21:12,228-0400 INFO (libvirt/events) [virt.vm] (vmId='7474280d-4501-4355-9425-63898757682b') reboot event (vm:1033) qemu [5]: 2020-06-29T14:21:12.260303Z qemu-kvm: terminating on signal 15 from pid 42224 (<unknown process>) 2020-06-29 14:21:12.462+0000: shutting down, reason=destroyed libvirtd [6] itself does not log anything relevant AFAICT, but at least it shows that the above unknown process is itself: 2020-06-29 14:18:16.212+0000: 42224: error : qemuMonitorIO:620 : internal error: End of file from qemu monitor (Note that above line is from 3 minutes before the reboot, and the only place in the log with '42224'. No other log there has 42224, other than these and audit.log). Any idea? Is this a bug in libvirt? vdsm? I'd at least expect something in the log for such a severe step.

Hyperconverged Single Host Glusterfs timing issue
by Glenn Marcy 30 Jun '20

30 Jun '20

Now that I've been able to get past my issues with q35 bios I decided to try the hyperconverged install. setting up the storage was no problem and the engine setup went fine until the point where it wanted to use that glusterfs storage. I got the error, pretty quickly I might add, of 2020-06-30 02:17:50,689-0400 DEBUG ansible on_any args <ansible.executor.task_result.TaskResult object at 0x7f83f85b4278> kwargs 2020-06-30 02:17:51,428-0400 INFO ansible task start {'status': 'OK', 'ansible_type': 'task', 'ansible_playbook': '/usr/share/ovirt-hosted-engine-setup/ansible/trigger_role.yml', 'ansible_task': 'ovirt.hosted_engine_setup : Add glusterfs storage domain'} 2020-06-30 02:17:51,428-0400 DEBUG ansible on_any args TASK: ovirt.hosted_engine_setup : Add glusterfs storage domain kwargs is_conditional:False 2020-06-30 02:17:51,429-0400 DEBUG ansible on_any args localhostTASK: ovirt.hosted_engine_setup : Add glusterfs storage domain kwargs 2020-06-30 02:17:53,656-0400 DEBUG var changed: host "localhost" var "otopi_storage_domain_details_gluster" type "<class 'dict'>" value: "{ "changed": false, "exception": "Traceback (most recent call last): File \"/tmp/ansible_ovirt_storage_domain_payload_jh42k_ip/ansible_ovirt_storage_domain_payload.zip/ansible/modules/cloud/ovirt/ovirt_storage_domain.py\", line 792, in main File \"/tmp/ansible_ovirt_storage_domain_payload_jh42k_ip/ansible_ovirt_storage_domain_payload.zip/ansible/module_utils/ovirt.py\", line 623, in create **kwargs File \"/usr/lib64/python3.6/site-packages/ovirtsdk4/services.py\", line 26097, in add return self._internal_add(storage_domain, headers, query, wait) File \"/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py\", line 232, in _internal_add return future.wait() if wait else future File \"/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py\", line 55, in wait return self._code(response) File \"/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py\", line 229, in callback self._check_fault(response) File \"/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py\", line 132, in _check_fault self._raise_error(response, body) File \"/usr/lib64/python3.6/site-packages/ovirtsdk4/service.py\", line 118, in _raise_error raise error\novirtsdk4.Error: Fault reason is \"Operation Failed\".

Fault detail is \"[Failed to fetch Gluster Volume List]\". HTTP response code is 400." }" The glusterfs cli worked fine by that point, had no issues with volume list, so I went into the node:6900/ovirt-engine forwarder to the appliance and could see that at the time of that error in the event logs there was a message that it was starting to update things and a few seconds later a message that the volumes were available. I am thinking that there is need for a retry loop in this step or that something in the path isn't waiting for something internal to complete before issuing the Operation Failed error.

Why are UI tests failing on ovirt-system-tests_manual ?
by Lucia Jelinkova 29 Jun '20

29 Jun '20

Hi all, If you're running manual OST tests Jenkins job [1] with custom repository pointing to your ovirt-engine Gerrit check patch job, you most probably notice that the UI tests are failing with one of the following errors: basic-suite-master.test-scenarios.100_basic_ui_sanity_pytest.test_left_nav[firefox] basic-suite-master.test-scenarios.100_basic_ui_sanity_pytest.test_virtual_machines[chrome] This is due to the fact that the normal check patch job does not always build GWT (first error) or it does not build GWT for both Firefox and Chrome (second error). If you want to test your ovirt-engine patch, please comment "ci build" on the patch, wait for the job to finish and use that job as a custom repository to run tests. I know that many devs know this "trick" but it might not be so clear for people not so long on the project. If you see any other issue, look into the screenshots or saved html in the exported artifacts. If you think it is a problem with tests, please contact me. Regards, Lucia 1: https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-test…

getVds().getInterfaces() is returning empty list of VdsNetworkInterface everytime
by Prajith Kesava Prasad 26 Jun '20

26 Jun '20

Hey Everyone, what I'm trying to achieve here is to get the list of network interfaces attached to each host, and then further get the ipv4Address from the corresponding attached logical network (as seen in the in the column in the image below). So i tried to get the list of interfaces of current host by getVds().getInterfaces() and it is returning an empty list of List<VdsNetworkInterface>. even though its showing in the UI. Could you tell me if I'm missing something? FYI:- (I'm ran vdsm-cliend Host getCapablities and getNetworkCapablities and it was returning correctly.) Regards, Prajith. [image: image.png]
