Creating an oVirt Engine Appliance on a different EL Distro (eg Rocky Linux)
by Matthew J Black 03 Oct '22

03 Oct '22

Hi All, Here's an interesting question: What is the process (ie the Step-By-Step process) to create an/the oVirt Engine Appliance based on another version of EL (ie in my case, Rocky Linux)? Is there a "Manual" somewhere? I mean, surely the oVirt Project's Release Manager has *something* that they follow to create the relevant rpm file - no? Cheers Dulux-Oz

ovirt-engine-appliance Location (Pre-Installation)
by Matthew J Black 03 Oct '22

03 Oct '22

Hi All, A couple of Qs: During the `TASK [ovirt.ovirt.engine_setup : Install oVirt Engine package]` stage of the Management Engine deployment, is this trying to install the ovirt-engine-appliance, or something else? When we do a pre-install of the ovirt-engine-appliance (ie dnf install ovirt-engine-appliance) where is this installed too, so that we can enter this information into the deployment script at the `Engine Appliance Image Path` stage? Cheers Dulux-Oz

Totally outstanding disk performance
by murilo＠evocorp.com.br 30 Sep '22

30 Sep '22

Good evening everyone. I'm implementing oVirt in my infrastructure using Ceph as Storage (I'm using 10 Gibabits interfaces), I managed to raise the Storage correctly, reaching rates of 1.2 Gigabytes per second via NFS. When I went to depoy the hosted-engine via NFS, everything went fine, but when I booted the first VM and tested the disk's performance, I got very low rates. Depending on how I'm writing to disk, I get rates of only 88 Megabytes per second, far below what was expected. Through FIO I get approximately 250 Megabytes per second, which is still quite low compared to what I can get via NFS on the same Host. I've already tried some Disk Cache configurations and tried to put CephFS as Storage Domain, but I always achieve the same rate, always with the IOPS quite low. Is there anything else I can do to try to improve these rates? Because I'm finding this quite weird considering how much data I can reach between the Host and Storage.

Uncaught exception on Network Interfaces tab of a newly added host to oVirt 4.5.0

I added a few hosts to oVirt that runs engine version 4.5.0.8-1.el8. Most of the hosts work well except that Network Interfaces tab of a host shows the below error on the web browser: Uncaught exception occurred. Please try reloading the page.

adding foreman as an external provider
by eevans＠digitaldatatechs.com 30 Sep '22

30 Sep '22

I had an ovirt engine failure which corrupted my foreman/katello vm. My ovirt-engine is 4.3 and I was using foreman 3.0 with Katello 4.5. Once the ovirt-engine was repaired, still 4.3, I updated the foreman katello install to foreman 3.3 and Katello 4.5. I can connect from foreman to Ovirt as a compute resource but cannot add foreman to ovirt as an external provider.

I believe it's a certificate error vnd renamed the katello certs with a .bak suffix. I'm not sure ifit's a compatability issue but I researched it to death and so far came up empty. Any help would be appreciated. Thanks, Eric

Storage domain deletion not possible because not possible to detach
by Diego Ercolani 28 Sep '22

28 Sep '22

(I'm always talking about the last ovirt version that is currently engine: 4.5.2.5-1.el8, node: ovirt-node-ng-4.5.2-0.20220810.0) I tried to add an iSCSI storage domain adding a new vlan network where the storage is attached.... this gave a completely mess-up of the storage engine. I would like to restart the procedure again and to accomplish this I have do remove the storage domain. To do this, I added manually the vlan to the nodes as I'm configured using linux bridge simple networking, so I discovered I have not to manage ovs environment. I currently have the storage domain in maintenance mode and I've successfully regenerated the discovery informations as the network to connecto to the storage is online. But I cannot detach the storage and I cannot activate the storage domain, so I'm completely stuck. This is the related log in the engine while I was trying to detach the storage: 2022-09-26 07:20:48,043Z ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.DetachStorageDomainVDSCommand] (EE-ManagedThreadFactory-engine-Thread-55008) [7a5a5413-36d0-4a15-b555-c9801f92483d] Command 'DetachStorageDomainVDSCommand( DetachStorageDomainVDSCommandParameters:{storagePoolId='da146814-f823-40e0-bd7b-8478dcfa38cd', ignoreFailoverLimit='false', storageDomainId='aac79175-ab2b-4b5b-a6e4-9feef9ce17ab', masterDomainId='00000000-0000-0000-0000-000000000000', masterVersion='8', force='false'})' execution failed: IRSGenericException: IRSErrorException: Storage domain not in pool: 'domain=aac79175-ab2b-4b5b-a6e4-9feef9ce17ab, pool=da146814-f823-40e0-bd7b-8478dcfa38cd' as you can see it seem there is a problem in the engine database. I saw here (https://lists.ovirt.org/pipermail/users/2015-January/030504.html) that someone worked directly on the engine db to delete the storage domain but I read somewhere else that the domain information is also mapped in a lvm volume metadata. What can I do from here? Thank you.

Editing vm devices
by Patrick Hibbs 28 Sep '22

28 Sep '22

Hello, I was trying to get some guest os hardware working and ultimately had to use the qemu-cmdline vdsm hook to set the pci bus id and address for a given vm device. I noticed that ovirt had a vmdevices tab in the Admin UI with this information in it, but it could not be edited. After looking through things I found this: https://www.ovirt.org/develop/release-management/features/virt/expose-vm-de… Apparently ovirt had at one point planned on allowing the administrator to change individual vm device properties, and some of this support such as the property persistence in the ovirt database, was already implemented. The only thing that seems to be missing is marking the fields in the Admin UI as editable, and the hook to update the database from those fields. Does anyone know if there are any plans on actually finishing this feature and getting it into a ovirt release? Or if not, why? The linked page is outdated, and claims the original target was ovirt 3.6. -Patrick Hibbs

ovirtmgmt Bridge - Which NIC? - Advice Please
by Matthew J Black 28 Sep '22

28 Sep '22

I need a quick piece of advice, please. I'm at setting up the oVirt Engine VM (ie doing a "hosted-engine --deploy") stage. The Host has 3 NICs. NIC_1 and NIC_2 are bonded (bond1) and run 2 VLANs (on bond1.1 and bond1.2). VLAN_1 is to be used as the "everyday connection VLAN for the VMs" (including the oVirt Engine VM - I think). VLAN_2 is *only* to be used for data traffic to-and-from our Ceph Cluster (ie via the Ceph iSCSI Gateway Nodes). NIC_3 (running VLAN_3) is to be used for oVirt-host-to-oVirt-host comms (including "local" Gluster traffic - yes, the (oVirt) hosts are running a couple of Gluster drives). My question is: Which interface should we use for the "ovirtmgmt" Bridge? I suspect it should be NIC_3 (VLAN_3), and I'm 99.999% sure it *shouldn't* be bond1.2 (VLAN_2), but it might be bond1.1 (VLAN_1), so I thought I'd better get peoples' input. You see, I'm not sure what the purpose of the "ovirtmgmt" bridge is. Is it for humans to talk to the oVirt Engine, or is it for the oVirt Engine to talk to the VMs (and hosts), or is it for some other purpose, or is it for some combination of the these? (I have read the doco on the ovirtmgmt bridge, and I'm still somewhat confused.) So, if someone wouldn't mind getting back to me about this, I'd appreciate it. Cheers Dulux-Oz

Backup/restore of Hosted Engine VM
by Volenbovskyi, Konstantin 27 Sep '22

27 Sep '22

Hi, I am aware that there is a procedure of backup/restore documented in https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/ht… , but I would like to have also else as well when it comes to backup (and restore) of hosted engine VM and avoid using hosted-engine --deploy / engine-backup Is anyone doing Libvirt snapshot or any other similar thing to back up ovengine VM? Part of that is the XML of the HE VM should be intact, so currently I am considering https://libvirt.org/kbase/live_full_disk_backup.html#full-backup-with-older… and https://gist.github.com/cabal95/e36c06e716d3328b512 BR, Konstantin
