Re: Problems with RHEL 9.4 hosts
by Devin A. Bougie
Unfortunately I’m not exactly sure what the problem was, but I was able to get the fully-updated EL9.4 host back in the cluster after manually deleting all of the iSCSI nodes.
Some of the iscsiadm commands printed worked fine:
———
[root@lnxvirt06 ~]# /sbin/iscsiadm -m iface
bond1 tcp,<empty>,<empty>,bond1,<empty>
default tcp,<empty>,<empty>,<empty>,<empty>
iser iser,<empty>,<empty>,<empty>,<empty>

———
But others didn’t, where the only difference is the portal:
———
[root@lnxvirt06 ~]# /sbin/iscsiadm -m node -T iqn.2002-10.com.infortrend:raid.sn8087428.012 -I bond1 -p 192.168.56.55:3260,1 --op=new
iscsiadm: Error while adding record: invalid parameter
———
Likewise, I could delete some nodes using iscsiadm but not others:
———
[root@lnxvirt06 ~]# /sbin/iscsiadm -m node -T iqn.2002-10.com.infortrend:raid.sn8087428.012 -I bond1 -p 192.168.56.54:3260,1 --op=delete
[root@lnxvirt06 ~]# /sbin/iscsiadm -m node -T iqn.2002-10.com.infortrend:raid.sn8087428.012 -I bond1 -p 192.168.56.55:3260,1 --op=delete
iscsiadm: Could not execute operation on all records: invalid parameter
[root@lnxvirt06 ~]# iscsiadm -m node -p 192.168.56.50 -o delete
iscsiadm: Could not execute operation on all records: invalid parameter
———
At this point I wiped out /var/lib/iscsi/, rebooted, and everything just worked.
Thanks so much for your time and help!
Sincerely,
Devin

Problems with RHEL 9.4 hosts
by Devin A. Bougie
Are there any known incompatibilities with RHEL 9.4 (and derivatives)?
We are running a 7-node ovirt 4.5.5-1.el8 self hosted engine cluster, with all of the hosts running AlmaLinux 9. After upgrading from 9.3 to 9.4, every node started flapping between “Up” and “NonOperational,” with VMs in turn migrating between hosts.
I believe the underlying issue (or at least the point I got stuck at) was with two of our logical networks being stuck “out of sync” on all hosts. I was unable to synchronize networks or setup the networks using the UI. A reinstall of a host succeeded but then the host immediately reverted to the same state with the same networks being out of sync.
I eventually found that if I downgraded the host from 9.4 to 9.3, it immediately became stable and back online.
Are there any known incompatibilities with RHEL 9.4 (and derivatives)? If not, I’m happy to upgrade a single node to test. Please just let me know what log files and details would be most helpful in debugging what goes wrong.
(And yes, I know we need to upgrade the hosted engine VM itself now that CentOS Stream 8 is now EOL).
Many thanks,

No valid authentication mechanism found
by Mathieu Valois
Hi everyone,
we've configured oVirt 4.5.5 with KeyCloak OIDC using an LDAP (FreeIPA)
backend.
When we wish to login on the portal, i.e
https://example.org/ovirt-engine, using the "Administration Portal" or
login directly with the button in the upper-right corner, it works (we
get redirected to keycloack and so on).
However, if we first try to login by clicking on the "VM portal", it
fails. We get redirected back to the portal having a "No valid
authentication mechanism found" error, as seen on the following screenshot.
Then, we're stuck until we clear the cache and cookies of the browser,
even when clicking on "Admin portal".
Backend logs only show this :
2024-06-04 11:56:24,319-04 ERROR
[org.ovirt.engine.core.sso.service.SsoService] (default task-86) []
Aucun mécanisme d'authentification valide trouvé.
which translates to the message seen on the screenshot.
Do you get any lead to resolve such an issue?
Thanks for your kind support,
Mathieu Valois

Connection to ovirt-imageio service has failed
by Денис Панкратьев
Hello!
I have ovirt hypervisor hosts (4.5.5, CentOS Stream 8) and hosted-engine VM (4.5.6-1.el8).
I want to upload .ISO to storage domain and get the following error:
"Connection to ovirt-imageio service has failed. Ensure that ovirt-engine certificate is registered as a valid CA in the browser."
But:
1. Valid CA installed in browser
2. On hosted-engine VM service ovirt-imageio is running (no prolbem)
What could be the problem, maybe someone has encountered it?

Re: Any plans on oVirt Major release with new feature?
by Alessandro
I don’t understand why Oracle isn’t taking the lead seriously. Olvm and oVirt could really be the “new vsphere” for on prem IaaS. Customer are still using VM, thousands of VMs.
I am struggling inside my company to try oVirt/olvm alongside vmware but how can we be sure that oVirt/olvm will not disappear in 1 or 2 years?
I saw an interview a month ago with storware and Oracle and althogh I understood that Oracle Linux KVM will still be here for many years, I didn’t feel the same for the management part hence the engine which is OLVM.
So, the question is for Oracle (which also contribute to oVirt) for how long (how many years) will they support and develop OLVM?
I hope to receive an answare.

Alessandro

VM Snapshot tab error Code 500
by doboscsongor＠gmail.com
Hi everybody,
I'm new to the oVirt environment, so I started with a fresh install on two physical servers using a hosted engine scenario. Currently, I have version 4.5.6-1.el8 installed. For storage, I am using FC to access our storage.
I have created a test VM for testing purposes where I installed MS Windows Server 2022. On the VM, I installed the guest tools, and everything is working fine except for the snapshots tab. If I don't have any snapshots for the VM, I can view the snapshots tab, but if I create a snapshot, the snapshots tab shows an error:
"Error while executing action: A request to the server failed with the following status code: 500."
Does anyone have any idea why I am getting this error?
Thanks in advance!
