Getting to know oVirt
by Alexandre Aguirre 18 Aug '22

18 Aug '22

I'm new to ovirt, I'm coming from Proxmox and VMware, so I had some doubts that I couldn't find myself; - Via terminal, where are the VMs created in oVirt? - What are the most used commands on a daily basis in the terminal? - Can I use the host's local disk as storage for the VMs? - Is glusterfs configuration native in ovirt, or do I need to install the part? Thanks in advance for your attention!!

ovirt version 4.5.1 I didn't see the tutorial on the ovirt official website, but I found the tutorial of Red Hat Hyperconverged Infrastructure for Virtualization. Should I follow this tutorial to execute, or through Cockpit, first pass the three machines of the second cluster through glusterfs ansible to form a cluster of storage Add to the new cluster in the engine web interface

by r greg 18 Aug '22

hi all, running 3x node hyperconverged setup (oVirt Open Virtualization Manager Software Version:4.5.1.3-1.el8) trying to migrate VM manually from UI and get the following error: "Could not fetch data needed for VM migrate operation" If I put the host into Maintenance, automatic migration of VM are done successfully. Checked this RH KnowledgeBase article (RHEV 4.4) but cannot find the conf file: https://access.redhat.com/solutions/5868721 New release 4.5.2 doesn't seem to list this as a bug: https://www.ovirt.org/release/4.5.2/#bug-fixes Has anyone experienced this before???

Clarify the cert renewal docs
by cen 17 Aug '22

17 Aug '22

Hi Speaking of this guide: https://www.ovirt.org/documentation/administration_guide/index.html#chap-Re… We have 2 hosts and one HostedEngine VM. It is unclear to me if step 1 should be done for all hosts first and then do the step 2, or if I should enroll host1 first, then run the engine-setup and then do the host2. It doesn't really make sense to run engine-setup again after enrolling host2 though, so that would make it 1 (host1), 2, 1 (host2), skip 2. Or does it? Best regards, cen

Cannot start VM after upgrade - certificate issue
by LAMARC 16 Aug '22

16 Aug '22

Hello, after running a PoC oVirt setup for more than a year, I ran into the "expiring certificate issue". Done an full upgrade for 4.4, engine-setup, and "Enroll certificates" to all hosts, all hosts are now green, and the certificates are renewed: - /etc/pki/vdsm/certs/vdsmcert.pem - /etc/pki/vdsm/libvirt-spice/server-cert.pem - /etc/pki/libvirt/clientcert.pem - /etc/pki/vdsm/libvirt-migrate/server-cert.pem But: I cannot start any VM any more. Getting: engine.log:2022-08-16 16:34:36,209+02 ERROR [org.ovirt.engine.core.bll.RunVmCommand] (EE-ManagedThreadFactory-engine-Thread-213) [60c5f661-6231-4e03-87a5-f6e6f2c63ad1] Command 'org.ovirt.engine.core.bll.RunVmCommand' failed: EngineException: (Failed with error NotAfter: Mon Aug 15 09:15:42 CEST 2022 and code 5050) Any ideas?

VM (live) migrate after update ovirt 4.2 -> 4.4
by Fabian Mohren 16 Aug '22

16 Aug '22

Hi, we have upgrade the Cluster (and all Hosts) to oVirt 4.4 and Oracle Linux 8.5 After the Upgrade, we cannot migrate VMs from one Host to another (same Cluster). oVirt stock, and on Hosts Tab we see the message (one the vm): "VM-CPU dosent match the Cluster-CPU". We checked the xml config from kvm We checked the DB for Cluster-CPU and VM-CPU - its the same (Cascadelake-Server-noTSX,-mpx). select name, cpu_name, cpu_flags from cluster; name | cpu_name | cpu_flags --------------------------+----------------------------------------+------------------------------------ TestMigrationCluster | Intel Haswell Family | vmx,nx,model_Haswell-noTSX select vm_guid, vm_name, cpu_name from vms where vm_name='oVirtTest'; vm_guid | vm_name | cpu_name --------------------------------------+-----------+--------------- 421ade0f-4d76-941d-3de2-13b1df54c89d | oVirtTest | Haswell-noTSX We create a new "TestMigrationCluster" with two Hosts for better testing. We reinstall the Hosts (OS + ovirt) = failed We reset the manager to an older State = failed We have no idea where the "Cluster-CPU check" is running? We search for a ansible role or play but nothing found Have anybody a idea where the Cluster CPU check is? Thanks & Regards Fabian

Changing Cluster Compatibility Version from 4.6 to 4.7 issue
by Alexandr Mikhailov 15 Aug '22

15 Aug '22

Hi! Just uprgaded from 4.4. to 4.5. Had all the problems with this update, such as postgresql-jdbc version and with stripeCount in cli.y . But I managed it, everything works more or less. Now I cannot raise the Cluster compatibility level. The problem is that increasing the level tries to change something in the HE configuration but cannot. This is error massage: Error while executing action: Cannot update cluster because the update triggered update of the VMs/Templates and it failed for the following: HostedEngine. "There was an attempt to change Hosted Engine VM values that are locked." is one of the error(s). To fix the issue, please go to each VM/Template, edit, change the Custom Compatibility Version (or other fields changed previously in the cluster dialog) and press OK. If the save does not pass, fix the dialog validation. After successful cluster update, you can revert your Custom Compatibility Version change (or other changes). If the problem still persists, you may refer to the engine.log file for further details. If i trying to edit HE machine without changing anything i se next error: There was an attempt to change Hosted Engine VM values that are locked/ I think this is linked issues. Log from engine log when i trying to update Cluster version: 2022-05-27 14:20:54,410+06 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-212) [1b8b6b78] EVENT_ID: CLUSTER_CANNOT_UPDATE_VM_COMPATIBILITY_VERSION(12,005), Ca nnot update compatibility version of Vm/Template: [HostedEngine], Message: There was an attempt to change Hosted Engine VM values that are locked.

Help please.
