oVirt Node 4.5.5 no virtualization tab
by arkansascontrols＠icloud.com
I have installed 4.5.5 and can get to the Web Interface at :9090 on all 3. I have been able to add the SSH keys and from any of the 3 hosts web interface I can get to the others from the drop down. But there is no Virtualization Tab on any of the 3, so no way to create VM's. I have followed a few instructions from some threads I've found on here
https://www.ovirt.org/dropped/gluster-hyperconverged/chap-Deploying_Hyper...
I subscribed all 3 hosts to the repo, and installed the engine, but the cockpit-ovirt-dashboard doesn't exist to install, and I'm guessing that's where I will find what I need to make this usable.
Any help would be appreciated.

New oVirt Node Installation, no web console access
by arkansascontrols＠icloud.com
I am setting a lab with a 3 nodes. I downloaded the latest oVirt node iso (4.5) and completed the install on all 3 nodes. When I browse to the node address I get a login screen that will not accept the root password. During the setup there is no opportunity that I have found to enter additional users, only an option to set the root password.
How do I access the Web Console? Any help would be appreciated.

HA Broker corrupting iSCSI Lockspace
by mblecha＠techmerx.com
I'm not sure how it happened, but a few hours ago, the lockspace for the hosted engine became corrupted. sanlock reports a -223 error.
CentOS 8 Stream, Ceph iSCSI backend (Reef at 18.2.4) using tcmu-runner.
I managed to format the lockspace, after shutting down the HA Agents and Brokers on all HA Engine nodes, but as soon as I start up the HA Agent on any node, the lockspace becomes corrupted again, and sanlock starts returning the -223 error message again. I see no relevant other errors in what I can find so far.
Any suggestions on where to investigate next? I have an entire cluster than cannot start/stop/migrate VMS as the entire DataCenter is marked Non Operational.

by weichao.jiao＠rayseconsult.com
Dear friends:
I am encountering an issue while attempting to deploy the oVirt Engine 4.5 on my local engine VM and I'm seeking guidance on how to resolve this.
Here's a summary of the error message I received during the deployment process:

Moving hosted engine to iscsi storage domain
by Devin A. Bougie
Hello,
We are attempting to move a hosted engine from an NFS to an iSCSI storage domain, following the normal backup / restore procedure.
With a little intervention in the new hosted engine VM, everything seems to be working with the new engine and the process gets to the point of trying to create the new iSCSI hosted_storage domain. At this point, it fails with "Storage domain cannot be reached. Please ensure it is accessible from the host(s).”
The host itself does see the storage, and everything looks fine using iscsiadm and multipath commands. However, if I look at the new hosted_storage domain in the new engine, it’s stuck “unattached” and the “hosted-engine --deploy --restore-from-file …” command loops at the "Please specify the storage you would like to use” step.
Please see below for an excerpt of the output and logs, and let me know what additional information I can provide.
Many thanks,
Devin
Here’s the output from the “hosted-engine --deploy --restore-from-file …” command.

ovirt hosts unassigned
by dragons＠namecheap.com
Hello,
we have found ovirt hosts in unassigned states after renewing certificates for oVirt engine via engine-setup --offline. The first launch ended with an error. We had an immutable attribute on the file /etc/pki/ovirt-engine/keys/engine_id_rsa
After which we removed the attribute and launched again engine-setup --offline.
In the events for each host we see the following errors:
VDSM ov3.example.com command Get Host Capabilities failed: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Is there any way to return the host to normal without losing data?

Re: [External] : Fallback Method to Start a VM if oVirt Engine is Offline
by Tommi Finance
Hi Marcos,
thank you so much for your feedback and clarification.
I've recognized you are a big player in the Oracle Universe; we are
currently migrating from Oracle VM Server to Oracle Linux Virtualization
Manager.
the target was to include also some other Servers from VMware Hypervisor.
Potentially this is a showstopper in our strategy but we will see.
thank you again
Thomas

Storage Domain Not synchronized, To synchronize them, please move them to maintenance and then activate.
by Arup Jyoti Thakuria
Dear All,
In our Ovirt Engine Infrastructure, recently we have received an alert for one of our "Storage Domain"
The alert is as mentioned below----
===================================
Storage domains with IDs [fb34e5b7-e850-4d66-ab47-3011d2000338] could not be synchronized. To synchronize them, please move them to maintenance and then activate.
==========================================================
What is the consequence of this alert, if we ignore this what can happen to the infra, are we going to face any issue with the VMs, currently this infra is under production
