Seven years ago, in June 2013, Giuseppe Valarelli introduced tests/functional/networkTests.py in https://gerrit.ovirt.org/#/c/14840/. It held high aspirations: to provide a comprehensive functional test for Vdsm's network API, in order to ease development of new code and reduce chances of reintroducing old bugs. 390 commits later, Andrej Cernak removed the last lines of code from that file in https://gerrit.ovirt.org/#/c/109182/. In between, many many other developers contributed to the set of tests, and later dissipated its content to multiple pytest-driven test modules. tests/functional/networkTests.py was never an emblem of great software design; it makes me happy to see it gone. But it was very useful and its spirit lives on: API tests are now the rule of Vdsm development, not an exception. I'd like to thank all the people who made this possible. $ git log 1c5f15c9b~ -- tests/functional/networkTests.py|grep Author|sort|uniq -c|sort -nr 72 Author: Edward Haas <edwardh(a)redhat.com> 58 Author: Ido Barkan <ibarkan(a)redhat.com> 46 Author: Ondřej Svoboda <osvoboda(a)redhat.com> 40 Author: Petr Horáček <phoracek(a)redhat.com> 35 Author: Dan Kenigsberg <danken(a)redhat.com> 34 Author: Antoni S.

Backup: how to download only used extents from imageio backend
by Michael Ablassmeier 02 Jul '20

02 Jul '20

hi, im currently looking at the new incremental backup api that has been part of the 4.4 and RHV 4.4-beta release. So far i was able to create full/incremental backups and restore without any problem. Now, using the backup_vm.py example from the ovirt-engine-sdk i get the following is happening during a full backup: 1) imageio client api requests transfer 2) starts qemu-img to create a local qemu image with same size 3) starts qemu-nbd to serve this image 4) reads used extents from provided imageio source, passes data to qemu-nbd process 5) resulting file is a thin provisioned qcow image with the actual data of the VM's used space. while this works great, it has one downside: if i backup a virtual machine with lots of used extents, or multiple virtual machines at the same time, i may run out of space, if my primary backup target is not a regular disk. Imagine i want to stream the FULL backup to tape directly like backup_vm.py full [..] <vm_uuid> /dev/nst0 thats currently not possible, because qemu-img is not able to open a tape device directly, given its nature of the qcow2 format. So what iam basically looking for, is a way to download only the extents from the imageio server that are really in use, not depending on qemu-* tools, to be able to pipe the data somehwere else. Standard tools, like for example curl, will allways download the full provisioned image from the imageio backend (of course). I noticed is that it is possible to query the extents via: https://tranfer_node:54322/images/d471c659-889f-4e7f-b55a-a475649c48a6/exte… As i failed to find them, are there any existing functions/api calls that could be used to download only the used extents to a file/fifo pipe? So far, i played around with the _internal.io.copy function, beeing able to at least read the data into a in memory BytesIO stream, but thats not the solution to my "problem" :) bye, - michael

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.
