install new ovirt 4.4 host
by Jiří Sléžka 04 Jun '22

04 Jun '22

Hi, I am around to install new ovirt 4.4 host on RockyLinux8 based server. I just install yum install http://mirror.slu.cz/ovirt/yum-repo/ovirt-release44.rpm but when I search for (for example) qemu-kvm package yum info qemu-kvm I can see only qemu-kvm-6.2.0-11.module+el8.6.0+847+b490afdd from appstream (RockyLinux slips to 8.6). It looks like ovirt-4.4-centos-advanced-virtualization repo does not have qemu-kvm at all yum list | grep ovirt-4.4-centos-advanced-virtualization Shoud I try to install new host from manager and hope or should I do some magic before? Thanks in advance, Jiri

why ovirtmgmt requires untagged network
by ravi k 03 Jun '22

03 Jun '22

Hello, I tried searching the archives but couldn't find anything related, so posting a new thread. When adding a new host to the cluster, why do we need to assign the IP on an untagged network in the bond? It is failing with error in setupnetworks when we tried it with the IP assigned to a vlan interface over the bond. For context, the cluster is an ovs-switch based cluster. It works when added to a traditional linux bridge based cluster. Can someone throw some light on this please? Regards, Ravi

HA VM Lease failure with full data storage domain
by Patrick Hibbs 02 Jun '22

02 Jun '22

OK, so the data storage domain on a cluster filled up to the point that the OS refused to allocate any more space. This happened because I tried to create a new prealloc'd disk from the Admin WebUI. The disk creation claims to be completed successfully, I've not tried to use that disk yet, but due to a timeout with the storage domain in question the engine began trying to fence all of the HA VMs. The fencing failed for all of the HA VMs leaving them in a powered off state. Despite all of the HA VMs being up at the time, so no reallocation of the leases should have been necessary. Attempting to restart them manually from the Admin WebUI failed. With the original host they were running on complaining about "no space left on device", and the other hosts claiming that the original host still held the VM lease. After cleaning up some old snapshots, the HA VMs would still not boot. Toggling the High Availability setting for each one and allowing the lease to be removed from the storage domain was required to get the VMs to start again. Re-enabling the High Availability setting there after fixed the lease issue. But now some, not all, of the HA VMs are still throwing "no space left on device" errors when attempting to start them. The others are working just fine even with their HA lease enabled. My questions are: 1. Why does oVirt claim to have a constantly allocated HA VM lease on the storage domain when it's clearly only done while the VM is running? 2. Why does oVirt deallocate the HA VM lease when performing a fencing operation? 3. Why can't oVirt clear the old HA VM lease when the VM is down and the storage pool has space available? (How much space is even needed? The leases section of the storage domain in the Admin WebUI doesn't contain any useful info beyond the fact that a lease should exist for a VM even when it's off.) 4. Is there a better way to force start a HA VM when the lease is old and the VM is powered off? 5. Should I file a bug on the whole HA VM failing to reacquire a lease on a full storage pool? -Patrick Hibbs

4.4.10 -> 4.5.0 upgrade fails
by Sketch 02 Jun '22

02 Jun '22

Just tried to upgrade my engine from 4.4.10.6 -> 4.5.0 on CentOS Stream 8. I relized I missed the step of updating to the very latest version of 4.4.10 around the same time it failed and left things in somewhat of a bad state, so I just built a new Rocky 8.6 host and restored my backup there. Update from 4.4.10.6 to 4.4.10.7 there went fine. 4.4.10.7 -> 4.5.0 fails with the same error, however: [ ERROR ] schema.sh: FATAL: Cannot execute sql command: --file=/usr/share/ovirt-engine/dbscripts/upgrade/pre_upgrade/0000_config.sql [ ERROR ] Failed to execute stage 'Misc configuration': Engine schema refresh failed This appears to be the relevant section of the log: psql:/usr/share/ovirt-engine/dbscripts/upgrade/pre_upgrade/0000_config.sql:22: NOTICE: column "default_value" of relation "vdc_options" already exists, skipping psql:/usr/share/ovirt-engine/dbscripts/upgrade/pre_upgrade/0000_config.sql:1454: ERROR: column "default_value" contains null values CONTEXT: SQL statement "ALTER TABLE vdc_options ALTER COLUMN default_value SET NOT NULL" PL/pgSQL function fn_db_change_column_null(character varying,character varying,boolean) line 10 at EXECUTE FATAL: Cannot execute sql command: --file=/usr/share/ovirt-engine/dbscripts/upgrade/pre_upgrade/0000_config.sql 2022-06-01 01:10:03,015-0700 ERROR otopi.plugins.ovirt_engine_setup.ovirt_engine.db.schema schema._misc:530 schema.sh: FATAL: Cannot execute sql command: --file=/usr/share/ovirt-engine/dbscripts/upgrade/pre_upgrade/0000_config.sql 2022-06-01 01:10:03,016-0700 DEBUG otopi.context context._executeMethod:145 method exception Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/otopi/context.py", line 132, in _executeMethod method['method']() File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine/db/schema.py", line 532, in _misc raise RuntimeError(_('Engine schema refresh failed')) RuntimeError: Engine schema refresh failed 2022-06-01 01:10:03,017-0700 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Misc configuration': Engine schema refresh failed Any ideas?

Updating oVirt Node
by Jonas 01 Jun '22

01 Jun '22

Hello all For Updates to the oVirt Node hosts I have seen two options in the documentation: - https://ovirt.org/documentation/administration_guide/index.html#Updating_al… - https://ovirt.org/documentation/administration_guide/index.html#Updating_In… Does anyone here have experiences with one or the other strategy or any recommendation of one over the other? I would like to update the hosts in intervals and not all at once, but as far as I understand it is only possible to update to the latest packages at the time of the update. Or is there a way to define something like a baseline for nodes using oVirt Engine? Thank you for your valuable input! Jonas

New Template dialog, clicking OK in one environment results in template creation, the other environment does nothing.
by mblecha＠flagshipbio.com 01 Jun '22

01 Jun '22

We have two oVirt environments configured, one for our Lab and one for Production. In the Lab, we can create templates. Clicking OK results in the New Template dialog disappearing and the VM's disk becomes locked and template creation begins. In the production environment, we cannot create templates. Clicking OK results in nothing, the dialog box remains. Nothing indicates missing/incorrect information. Both environments are on hosted engines, and oVirt Engine version 4.5. I have monitored the logs in the production environment and nothing comes up when the OK button is clicked. I have tested both environments in both Firefox and Chrome, and the behavior is also the same, our lab will progress, but production will simply not budge.

new cluster, 6 nodes
by bpbp＠fastmail.com 31 May '22

31 May '22

Hi all, planning a new 6 node hyper-converged cluster. Have a couple of questions 1) storage - I think we want to do 2x replicas and 1 arbiter, in the chained configuration seen here (example 5.7) https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/h… any suggestions on how that looks from the bottom up? for example does each host have all their disks in a single hardware raid6 volume, and then the bricks are thinly provisioned via LVM on top so each node has 2 data and 1 arbiter bricks. or is something else recommended? 2) setup - Do I start with a 3 node pool and extend to 6 or use ansible to set up 6 from the start? Thanks

How to update Ovirt nodes (installed from pre-built ovirt-node-ng .iso) from 4.4.10 -> 4.5
by morgan cox 30 May '22

Hi. hi - wondering if anyone can advise me, how to update Ovirt nodes (installed from pre-built image iso (i.e https://resources.ovirt.org/pub/ovirt-4.4/iso/ovirt-node-ng-installer/4.4.1… ) from 4.4.10 -> 4.5 ? I have a rhel8.6 server as the engine (standalone) - when i successfully updated already - using guide from -> https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_to… And the engine has now been successfully upgraded to 4.5 But all our Ovirt nodes/hosts have been installed via pre-built ovirt-installer-ng .iso - which is based on CentOS Stream release 8 i.e on the nodes I see - cat /etc/redhat-release -> CentOS Stream release 8 Presently the 4.4.10 nodes (from pre-built image) show no updates in the Ovirt engine do i need to do the steps here -> https://ovirt.org/download/install_on_rhel.html on an ovirt node installed from the ovirt-node-ng iso as it reads like it is just nodes based on rhel, etc you need to . Any advice of how to update the nodes would be welcomed Thanks
