Impossibile to install a new system
by Andrea Chierici
Dear all,
I've been struggling with a new ovirt installation for several weeks but
I seem to have no luck at all.
I've tried both starting from a centos8 stream system and a ovirt-node,
but the engine installation always breaks here:
TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up]
I keep getting the same problem, it looks like the engine is not
"migrated" to the public ip and is stuck on the natted address that the
installation process is using during the preliminary phase.
Here is a message that seems to confirm my theory:
2023-09-19 15:43:29,259+0200 DEBUG
otopi.ovirt_hosted_engine_setup.ansible_utils
ansible_utils._process_output:109 {'msg': "The task includes an option
with an undefined variable. The error was: 'local_vm_ip' is
undefined\n\nThe error appears to be in
'/usr/share/ansible/collections/ansible_collections/ovirt/ovirt/roles/hosted_engine_setup/tasks/sync_on_engine_machine.yml':
line 2, column 3, but may\nbe elsewhere in the file depending on the
exact syntax problem.\n\nThe offending line appears to be:\n\n---\n-
name: Set the name for add_host\n ^ here\n", '_ansible_no_log': False}
2
I know the problem the development of ovirt is facing lately, but I am
simply wondering: is there a way to install ovirt 4.5.4 today or is it
all already lost??!
Any kind of help would be really appreciated.
Thanks,
Andrea

oVirt 4.5.4-1: engine-setup does not renew certificates
by Lars Stolpe
Hi,
I wanted to add short names to the webgui apache certificate. I followed these instructions:
„Engine can be accessed using alternate host names (or IP addresses) that can configured by adding a new configuration file (for example /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf) with following content: SSO_ALTERNATE_ENGINE_FQDNS="alias1.example.com alias2.example.com" The list of alternate names has to be listed separated by spaces. It's possible to add also IP addresses of engine host, but using IP addresses instead of DNS names is not considered to be a good practise. Run engine-setup to generate new certificates.“
Certificates where not renewed. How do i get engine-setup to renew the apache certificate?
oVirt: 4.5.4-1

Gluster: Ideas for migration
by jonas＠rabe.ch
Hello
I have to migrate the Gluster volumes from an old oVirt cluster to a newly built one. I looked into migration strategies, but everything that Red Hat recommends is related to replacing old bricks. In a testing environment I created two clusters and wanted to migrate one volume after the other. Unfortunately that fails because a node cannot be part of two clusters at the same time.
The next thing I see, is to recreate the volumes on the new cluster, then constantly rsync the files from the old cluster to the new one and at a specified point in time make the cut over where I stop the applicaiton, do a final rsync and remount the new volume under the old path.
Is there any other, nicer way I could accomplish migrating a volume from one Gluster cluster to another?

How to turn off this checks?
by Jorge Visentini
Hi guys,
Is it possible to disable these checks?
*1 - Failed to verify Power Management configuration for Host
ovirtHost.domain.*
*2 - Available swap memory of host ovirtHost.domain [2 MB] is under defined
threshold [1024 MB].*
I know that is not a good practice, but I don't need it for now.
Thanks all!

Version 4.5. How should I properly replace a failed host?
by ziyi Liu
gluster uses 2+1 arbitration mode
My host is damaged and I need to reinstall the system. The host fqdn still uses the old fqdn. What should I do?
I found some historical information. Is it still usable for the new version?
Found gluster-ansible in GitHub
https://github.com/gluster/gluster-ansible/blob/master/playbooks/hc-ansib...
See the instructions and configure node_prep_inventory.yml and node_replace_inventory.yml to restore.
Execute ansible-playbook -i node_prep_inventory.yml -i node_replace_inventory.yml tasks/replace_node.yml
My data disk /dev/sdb has also been initialized by me. Can this ansible script help me create a new partition, create a mount, and complete the recovery of the gluster node?

ssl stomp reactor timeout
by Chris Smith
Hi all,
I'm using ovirt 4.2 so I'm a little behind, but I'm trying to understand
what this error message means.
ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (SSL Stomp
Reactor) [] Connection timeout for host 'x.x.x.x', last response arrived
1549 ms ago.
Is this initiated by the engine server or the ovirt host ?
Is there a way for me to replicate what ovirt is doing manually via a
telnet or curl type command ?
Thanks,

Testing oVirt backup and Restore operations 4.3
by Mikhail Po
There was a desire to conduct a test backup and restore operation ovirt-node-ng 4.3.2-2019031908
Operations performed:
- Deployed two test hosts, configured Hosted Engine. Created two test VMs.
- Created a backup copy
# engine-backup --mode=backup --file=ovirt-full-backup_2023-09-04.tar --log=ovirt-full-backup_2023-09-04.log
- Turned off the original Self-hosted Engine and disconnected from Self-hosted Domain Storage
# hosted-engine --vm-shutdown
# hosted-engine --disconnect-storage
- Created a new host using a previously created backup
# hosted-engine --deploy --restore-from-file=ovirt-full-backup_2023-09-04.tar
Although an error occurred at the end of the installation (after the start of copying to the iSCSI shared storage), but oVirt is accessible via the Web. The error that occurred
[ INFO ] TASK [ovirt.hosted_engine_setup : Check for the local bootstrap VM]
[ ERROR ] Error: The response content type 'text/html; charset=iso-8859-1' isn't the expected XML
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook
...
[ INFO ] Stage: Clean up
[ INFO ] Cleaning temporary resources
[ ERROR ] Hosted Engine deployment failed: please check the logs for the issue, fix accordingly or re-deploy from scratch.
Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20230907201859-ovmmky.log
In the Web interface
- all Hosts are green
- all VMs are green. There is a virtual machine "external-HostedEngineLocal".
- Storage Domain "hosted_storage_old_20230907T202958" is present.
Any questions:
1. The instructions say that at the end you need to reinstall the hosts. Is it necessary to do this? I ask, because in my case, all hosts are available to the manager, virtual machines are working. What is this operation necessary for?
2. What to do with the "external-HostedEngineLocal" virtual machine?
3. Why the "Error" error occurred: The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"? Can it be related to the lack of access to the Internet (repository) have a VM Engine? When installing hosts, access to the Internet is required (otherwise the installation does not occur), I register access through a proxy in yum.conf
