Backing up VMs with qemu-img
by David White 08 May '22

08 May '22

I've recently been working with the qemu-img commands for some work that has nothing to do with oVirt or anything inside an oVirt environment. But learning and using these commands have given me an idea for automating backups. I believe that the following is true, but to confirm, would the qemu-img commands be available on the oVirt hosts to take VM snapshots and disk images? Sent with ProtonMail secure email.

OVIRT Engine Restore from old Backup
by Abe E 07 May '22

07 May '22

Hey All, I really dont like spamming the forums but the issues I am having keep changing entirely. I am at the point where I can get much closer to rebuilding my engine although my hurtle currently is restoring. When I restore using my most recent backup it is problematic Currently I am restoring by: clean engine install engine-cleanup engine-backup --mode=restore --file=ovirt-engine-backup-20220504011012.backup --log=restore5.log engine-setup Comes up with alot of annoyances as the ID of the old hosted_storage and the new one are mismatched in the GUI. On top of that it is not allowing me to deploy the engine to the 2nd Gluster (3rd one keeps deleting its glusters on reboot since 4.3 Upgrade). Host 1 which runs the hosted engine is not showing as active or unlike, rather it is unresponsive, when I tried to enroll certificates it finally accepted but failed because it said its missing networks, once added it crashed the engine and ha agent wouldnt come up. Now that I think of it, I could have removed the extra networks from being required although it still doesnt benefit me here as I am unable to deploy or reinstall the 2nd Gluster node and the first one will not show its correct state as the host. Should I just be deploying the DB, or is the full file backup fine? My issue here is it takes long to redeploy so the trial an error of failing takes me hours as my backup is from 4.5 engine even though my nodes are on 4.4 as 4.5 keeps causing the catastrophic failure of my whole cluster.

i need change legacy to ovs switch mode on oVirt node's
by sultanu＠inbox.ru 06 May '22

Hello, Team! I need help. I have cluster with 3 nodes oVirt 4.4.10 and common ISCSI storage, i have hosted engine installed on it. I wont change legacy to ovs switch mode, using instruction below: - Install first host and VM using "hosted-engine --deploy" - In the Engine UI, change Cluster switch type from Legacy to OVS - Shutdown the engine VM and stop vdsmd on the host. - Manually change the switch type to ovs in /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt - Restart the host After this changing my hosted engine don't wont start, it says i have a problem with vnet interface, i don't know virtmanager or i don't know vnetuser. When i had return back settings from ovs to legacy mode, hosted engine start without any problem When i had change file /var/lib/vdsm/persistence/netconf/nets/ovirtmgmt on hosts without hosted engine, they are change network mode and start working as ovs switch mode but they say network out of sync. I tryed to migrate hosted engine from host with legacy switch to host with ovs switch hosted engine don't wont migrate. Could you help me please.

could not start ovirt-engine: TagsDirector.init() fails
by Liebe, André-Sebastian 06 May '22

Hello list, I'm unable to start ovirt-engine after switching from CentOS 8 to CentOS 8-stream, doing a system update and a reboot. A previously done ovirt update from 4.4.9 to 4.4.10 (w/o system reboot but with service restart) went smoothly, so I guess it's somehow caused by one oft he centOS updates? The root cause logged in server.log reads: > org.springframework.dao.InvalidDataAccessApiUsageException: Unable to determine the correct call signature - no procedure/function/signature for 'gettagsbyparent_id' But according to ovirt-engine-setup-*.log a GettagsByparent_id(v_parent_id UUID) function ist created duging engine-setup (which I run after dnf update). When searching google for " org.ovirt.engine.core.bll.TagsDirector.init()" and "'gettagsbyparent_id" I got some results hinting for a faulty PosgreSQL jdbc driver from 2018 Any hints? sincerely André-Sebastian Liebe Zukunftslabor gematik GmbH | Friedrichstr. 136 | 10117 Berlin Tel +49 30 40041-197 | Fax +49 30 40041-111 andre.liebe(a)gematik.de | www.gematik.de Amtsgericht Charlottenburg HRB 96351 Geschäftsführer: Dr. med Markus Leyck Dieken

Re: Getting error on oVirt installation
by Kevin Cahill 06 May '22

I am also struggling with this as I try to install a self-hosted engine. I have read every thread in the forum and tried all the suggestions. Here is my most recent attempt (RHEL 8.5, installing oVirt 4.4): Start the hosted engine deployment, then run the command [ # dnf downgrade postgresql-jdbc ] from a virsh console, to downgrade postgresql as soon as the packages are done updating. The downgrade appears to be successful, however the system still fails at 'Check if engine health page is up'. Restarting the oVirt engine [ # systemctl restart oVirt-engine ] immediately after downgrading postgresql does not make any difference. The system times out at the 'Check if engine health page is up'. The log entry where the latest failure started to occur is below. I can include the entire log if needed. Interestingly, the status was 503 this time. In many prior attempts that status was 500. 2022-05-06 09:42:49,744-0400 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:110 fatal: [localhost -> 192.168.222.150]: FAILED! => {"attempts": 30, "changed": false, "connection": "close", "content": "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>503 Service Unavailable</title>\n</head><body>\n<h1>Service Unavailable</h1>\n<p>The server is temporarily unable to service your\nrequest due to maintenance downtime or capacity\nproblems.

If so, any pointers would be greatly appreciated. If I get this working I will follow up with exactly what I did.
