grafana @ ovirt 4.5.0.6 "origin not allowed"
by diego.ercolani＠ssis.sm 12 May '22

12 May '22

Hello, in my current new installation ovirt-engine-4.5.0.6-1.el8.noarch I have a problem setting up the grafana monitoring portal. I'm supposing that there is some problem regarding connection to ovirt DWH DB. I tested the credentials stored in /etc/grafana/conf/provisioning/datasources/ovirt-dwh.yaml of the ovirt-engine and with psql it seem to work and also the DWH is populated by the engine. But connecting to configuration->data sources and trying to reconfigure the ovirt dwh datasource, when you click on "save & test" it appears a popup telling that the "origin not allowed". I cannot find anything in the grafana log or the httpd log. Can you help?

Console error
by Andrea Chierici 11 May '22

11 May '22

Hi, yesterday I've migrated from 4.4.10.7-1 to 4.5.0.7-1. Installation went fine and no error at all was reported. A problem anyway is now hitting my installation: if I try to open a vm console, I get the error: Failed to complete handshake Error in the pull function It's not a problem on my browser/os since with another 4.4.x ovirt installation, consoles work flawlessly. No modifications at all were made to default settings on console. Any suggestion on how to solve this issue? Haven't seen any previous report on this. Thanks, Andrea

oVirt and cluster level 4.7
by Gianluca Cecchi 11 May '22

11 May '22

Hello, I've not had the chance to try 4.5 yet, but in a thread I saw reference to a supposed cluster level 4.7. I didn't find anything special in release notes about it, its features and matrix of compatibility levels usable in 4.5 (only 4.7 up or what?) I found this bugzilla, now closed, where in some part it was asked to file a doc part https://bugzilla.redhat.com/show_bug.cgi?id=2021545 Any further information? BTW: what are the versions of libvirt and qemu-kvm used in latest 4.5.x? Thanks, Gianluca

OVIRT Engine Restore from old Backup
by Abe E 11 May '22

11 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.

FC Storage recover
by csabany＠freemail.hu 10 May '22

10 May '22

Hi, We have a 4 node cluster (4.4.10) and a standalone manager. We attached to this cluster 4 volumes on FC. Last week we lost the storage canisters (both), but recovered one of them from the storage disks. Unfortunatly only 3 storages came back from offline. I see the 4th FC ID, but it's on "Can't Extend" status. If i check the storages on nodes (lsblk), i can see only the ID not more on this 4th storage. Do you know any recovery tool or any idea for this situation? Thanks csabany
