What you need is the list of disks in the vms, accessible via: GET /vms/{vm-id}/diskattachments For each disk attachment, get the disk using the diskattachment.disk.id: GET /disks/{disk-id}/ Please check how we do this in backup_vm.py example: https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/backup... > by using `GET vms/<vm-id>/snapshots`, but get the following error. > > <?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> We need a much more detailed steps. 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/ac6f05bb5dcd8fdee2a67b2a29... 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/ac6f05bb5dcd8fdee2a67b2a29... 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? Maybe you do not wait until the previous image transfer was finished before starting a new backup? > After this, on oVirt engine web console, the VM show 2 disks (actually it only has 1) , and the disk status always showing “Finalizing”, it’s been more than 30 hours now, and during this, cannot modify VM disk or take snapshots. > > Before upgrading oVirt engine to 4.4.7.7-1.el8 this problem happened frequently, after upgrading, the frequency is reduced. > > Here I’m adding the engine logs and vdsm logs. > Engine logs: https://drive.google.com/file/d/1T3-EOxYYl3oFZOA9VMMBte5WyBoUO48U/view?us... > VDSM logs: https://drive.google.com/file/d/1x0B8lGqnKEDrgn666CuN3hqUGwD7fcYv/view?us...

This year conference community updates

by Sandro Bonazzola

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.*

ovirt-provider-ovn git repo got broken

by Sandro Bonazzola

Hi, not sure what happened but ovirt-provider-ovn repo in gerrit (and its backup on github) now contains a bunch of ovirt-engine tags shipping ovirt-engine content.

Re: RHV and oVirt CBT issue

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

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.

lago is dead, long live ost!

by Michal Skrivanek

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
