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

Error: Adding new Host to ovirt-engine
by Ahmad Khiet 14 Aug '23

Hi, Can't add new host to ovirt engine, because the following error: 2019-06-12 12:23:09,664 p=4134 u=engine | TASK [ovirt-host-deploy-facts : Set facts] ************************************* 2019-06-12 12:23:09,684 p=4134 u=engine | ok: [10.35.1.17] => { "ansible_facts": { "ansible_python_interpreter": "/usr/bin/python2", "host_deploy_vdsm_version": "4.40.0" }, "changed": false } 2019-06-12 12:23:09,697 p=4134 u=engine | TASK [ovirt-provider-ovn-driver : Install ovs] ********************************* 2019-06-12 12:23:09,726 p=4134 u=engine | fatal: [10.35.1.17]: FAILED! => {} MSG: The conditional check 'cluster_switch == "ovs" or (ovn_central is defined and ovn_central | ipaddr and ovn_engine_cluster_version is version_compare('4.2', '>='))' failed.

lago is dead, long live ost!
by Michal Skrivanek 04 Aug '21

04 Aug '21

Hi, we worked for a while on removing our dependency on lago that has been more or less abandoned for a long time now. We got to the minimal feature set that is simple to replace with bunch of virsh commands, and most of the advanced logic is implemented in pytest. We’ve just merged the last patches that freed us up from lago for local and beaker CI runs. There’s a new ost.sh wrapper for the simple operations of running the suite, inspecting the environment and shutting it down. Hopefully it’s self explanatory…. ./ost.sh command [arguments] run <suite> <distro> [<pytest args>...] initializes the workspace with preinstalled distro ost-images, launches VMs and runs the whole suite add extra repos with --custom-repo=url skip check that extra repo is actually used with --skip-custom-repos-check status show environment status, VM details shell <host> [command ...] opens ssh connection console <host> opens virsh console destroy stop and remove the running environment Right now lago and run_suite.sh still works and it is still used by the mock-based jenkins.ovirt.org runs. It will go away in future. Thanks, michal

This is a typical backup flow: 1. Start incremental backup 2. Wait until backup is ready (phase == READY) 3. Start image transfer for incremental backup 4. Wait until image transfer is ready (phase == TRANSFERRING) 5. Download disk incremental data 6. Finalize transfer 7. Wait until transfer is finished (phase == FINISHED_SUCCESS/FINISHED_FAILURE) This is not easy, see this example: https://github.com/oVirt/ovirt-engine-sdk/blob/ac6f05bb5dcd8fdee2a67b2a296a… 8. Finalize backup 9. Wait until backup is finished (phase == FINISHED/FAILED) This is easier, but possible only since 4.4.7: https://github.com/oVirt/ovirt-engine-sdk/blob/ac6f05bb5dcd8fdee2a67b2a296a… 10. Rebase backup image on previous backup (if you store backup as qcow2 layers) Where in this flow you get the snapshot list (and other stuff?) Getting snapshots list is likely not needed for backup, but we need to fix it in case it is broken while running backups or image transfers. Do you run this flow in a loop?

This year conference community updates
by Sandro Bonazzola 30 Jul '21

30 Jul '21

Hi, as announced we are going to have oVirt online conference coming in September. I would like to give usual community updates in and as part of that I'd like to report about oVirt downstream products (such as Red Hat Virtualization and Oracle Linux Virtualization Manager) and about companies using oVirt. I could just go googling and guessing by e-mail traffic on oVirt users list but I want to try a different approach this year. So, if you are shipping an oVirt downstream or if you're using oVirt and you'd like to get the company nominated during the community reports please let me know off-list. Also I'd like to remind that oVirt site has a section dedicated to user stories, if you want to share yours you can either push it to https://github.com/oVirt/ovirt-site or get in touch with me off-list to get help getting your story published. Thanks, -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/> *Red Hat respects your work life balance. Therefore there is no need to answer this email out of your office hours.*

If the image transfer is "finalizing" it means the image transfer is trying to finalize, but the operation could not complete. In this phase the disk remains locked, and it should not be possible to start a new image transfer (e.g perform another backup). Engine and vdsm logs should explain why the image transfer is stuck in the finalizing phase. Can you add detailed instructions on how to reproduce this issue?

after a regular backup, VM got duplicated disks and disks' status always in Finalizing
by luwen.zhang＠vinchin.com 30 Jul '21

Version: oVirt engine: 4.4.7.7-1.el8 oVirt node: 4.4.7 Steps of reproducing the problem: After a series of regular/successful backup tests by using CBT+imageio API, at one of the backup session beginning, when trying to obtain the VM config and snapshot list (obtain snapshot list can determine the VM disk is in RAW or QCOW2 format) by using `GET vms/<vm-id>/snapshots`, the below error is received. <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <fault> <detail>duplicate key acf1edaa-e950-4c4f-94df-1bd6b3da49c1 (attempted merging values org.ovirt.engine.core.common.businessentities.storage.diskimage@5103046c and org.ovirt.engine.core.common.businessentities.storage.diskimage@d973046c)</detail> <reason>Operation Failed</reason> </fault> After this on the oVirt engine web console, we saw the VM which should only have 1 disk is now showing 2 disks, the disk status always in Finalizing state. It's been more than 30 hours but the VM still got duplicated disks and still showing Finalizing, there's no way to modify the virtual disk or take snapshots for the VM.
