Does anyone have any idea why I find the old, now decommissioned, Centos site in the engine configuration? Tnx

Items to be repaired entries
by ziyi Liu 27 Mar '25

27 Mar '25

One of my hosts is faulty and needs to be replaced with a good one. The new host uses the same host name as the old host and the same backend storage name. The recovery process is as follows: 1. Delete the storage volume of the faulty host and the storage volume of the arbitration node. 2. Use the glusterfs ansble script to restore the faulty host. (Create partitions and join peer nodes) 3. Add the storage volume of the new host 4. Wait for data recovery During the data recovery process, it is always stuck at Items to be repaired entries How should I deal with these items

network out of sync
by Nathanaël Blanchet 19 Mar '25

19 Mar '25

Hi, After reinstalling ovirt hosts with alma Linux 9, all my hosts are out of sync on the management bridge. I tried to sync them, but it has no effects. Then I tried "static" and "DHCP" but it has no effect as well. I precise that I was using ovirt node 4.5.5 el9, and the bug wasn't present. It seems to be a bug because, network is okay and there is no other issue using alamlinux 9.5 with latest vdsmd. Thank you for helping. -- Nathanaël Blanchet Administrateur Systèmes et Réseaux Service Informatique et REseau (SIRE) Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Problem with deleting snapshot - no responging VM
by Urbanski.r＠gmail.com 18 Mar '25

18 Mar '25

Hello, I have ovirt-engine version 4.5.6-1.el9, and nodes version 4.5.5. We have about 200 VMs in the environment. So far, backups were performed using snapshot + ovirt API + AWX. The problem started when during backup some machines became unresponsive (it was impossible to get to the console and it happened randomly), Prellocated disks became ThinkProvisioning and it was not possible to delete the snapshot. We decided to skip all scripts and click the snapshot directly in ovirt-engine and then delete it in order to merge. In many cases, these tasks ended successfully, and in random situations the process hung again and the machine became unresponsive. I thought..... maybe it was a performance problem (network to the array, the array itself, etc.). So we set up the dev environment on different hardware (different physical servers and different hardware with ISCSI). I copied one of the sample machines that had problems. I made a snapshot again and merged it using deleting from the ovirt-engine interface. It worked a few times and I decided to do another test I made a snapshot of the test VM and logged into it and used a file about 16GB in size and additionally copied it to another place on the disk and then tried to merge the snapshot and again the VM became unresponsive and it was impossible to delete the snapshot. Has anyone encountered such a problem and has a way to solve it? I am attaching the logs from /var/log/ovirt-engine/engine.log https://pastebin.pl/view/e6e01717

Could you please check if terminal is set before taking console. # echo $TERM # hosted-engine --console Also does it work even hosted engine status is in bad status

Hi All, https://ovirt.org/documentation/planning_and_prerequisites_guide/index.html Is newly added. I know if has some old material in it as it embeds older documentation segments. Now is your chance to raise issues and i'll fix them. There is a link at the bottom of the page to raise an issue, but here it is for you as well https://github.com/oVirt/ovirt-site/issues/new?labels=documentation&title=I… Please provide feedback on this or any other piece of documentation. Thanks Geoff

Unable to set up host bond networks
by erik＠linux.com 17 Mar '25

17 Mar '25

Hi We are trying to create a cluster using OLVM 4.5 (with an up to date OEL8 kernel) with a bond of 2 virtual interfaces (mode 2 XOR) that we have set up with NetworkManager prior to adding the KVM host to oVirt. Hosts are added successfully and we can see the two physical NICs (eth0/eth1) in the Setup Host Networks dialog, however the bond0 device is hidden as are the virtual slave interfaces (so we cannot create the bond in oVirt either). It appears the bond0 is sent to oVirt by VDSM as we see it is continually sent in the vdsm log file from the host as well as listed in the capabilities using vdsm-client. We didn't find obvious errors in ovirt-engine.log or in host-deploy or in the vdsm logs on the KVM hosts. We assume there is some validation or filtering oVirt uses that is hiding the bond / slave interfaces and that maybe our slave interfaces are missing some property oVirt wants but we cannot find it in the code in order to work around this - any pointers appreciated. Thanks Erik

Yes I did.. But it is like stuck and not giving any prompt. Did we need to set terminal on kvm side. Also do you have any steps to perform prior to taking console?
