Can't create shared disk after upgrade to 4.5.4
by Igor Filipovic
Hi,
In my lab I'm using OLVM ( I know ... it's not original oVirt but it is based on it ). I was using 4.4.10, and after upgrade to 4.5.4 I'm no longer able to create shared disks, on any storage domain (nfs or fc). When I was on previous release I was able to create and use shared disks (required for cluster systems), but after upgrade when I try to create shared disk (preallocated) I'm getting an error saying : Error while executing action: Cannot add Virtual Disk. Disk's volume format is not supported for shareable disk.
In engine log I can see only this :
2024-03-31 20:04:28,997+02 WARN [org.ovirt.engine.core.bll.storage.disk.AddDiskCommand] (default task-37) [b8bc1831-260a-4253-b6fe-e0c81a6f81b6] Validation of action 'AddDisk' failed for user admin@internal-authz. Reasons: VAR__ACTION__ADD,VAR__TYPE__DISK,SHAREABLE_DISK_IS_NOT_SUPPORTED_BY_VOLUME_FORMAT
Does anyone have idea what could be the reason or how to solve this?
Thanks in advance and best regards

Re: Recreate engine without backup
by Igor Filipovic
Hi, I managed to resolve this issue.
Long story short :
- take configuration details from hosts about disks (especially if direct disks are being used, commands like multipath -ll, lsblk, blkid...)
- take a xml dump from all running VM's
- install new standalone engine
- add existing hosts to new image (running machines were detected with prefix "external"
- configure logical networks after checking hosts network adapters
- if direct disks exists in your configuration, create virtual disks for them by using xml dump files and info from hosts
- shutdown running vm's (all with prefix "external")
- shutdown all kvm hosts and left only one kvm host running (to prevent sanlock)
- import existing storage domain from running host
- use VM import tab in Storage domain to view vm's available for import
- delete machines with prefix "external" because import detect machines with same VM ID
- run import VM's from storage domain, one by one ... and that's it, after import run the machines
***If there are no VM's listed in VM import tab after adding storage domain, than you need to import disks from Disk import tab in storage domain, and then manually create virtual machines with information from xml dump files (to be able to configure disks,networks,cpu,ram ... like it was originally configured). After creating VM's you should be able to run them.***
Maybe it can help someone.

FQDN error while creating ovirt engine
by Marouane
Hi All,
I'm using a fresh 4.5.5 install, when I try to create the ovirt engine, I get the below error :
The task includes an option with an undefined variable. The error was: list object has no element 0. list object has no element 0\nThe error appears to be in '/usr/share/ansible/collections/ansible_collections/ovirt/ovirt/roles/hosted_engine_setup/tasks/fetch_host_ip.yml': line 32, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n when: hostname_resolution_output.rc != 0\n - name: Parse host address resolution\n ^ here\n
I tried adding entries to my DNS or setting the local /etc/hosts as follows:
192.168.1.2 ovirt-engine-01 ovirt-engine-01.localdomain
in both cases I get the same error...Any ideas how to fix this?

Abnormal behavior on the reinstalled host
by ricardoot＠gmail.com
Hello everyone,
I need help again with a host that I have reinstalled l and I don't understand why it doesn't work well.
I have managed to get the host status to UP. But I can't migrate MV to this host. Yes, I can start a VM on this host and I can migrate it to another but it can't go back if you want.
These are the errors I see:
ID: 128
2024-03-19 20:34:56,809+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-77603) [6ea57120-4e64-4b1d-a31f- 1072f69c478b] EVENT_ID: VM_MIGRATION_TRYING_RERUN(128), Failed to migrate VM srvlinux to Host ovirt51.mydomain due to an Error: Fatal error during migration. Trying to migrate to another Host.
It also happens that I cannot access the noVNC console on this Host but the VM is running. It gives me this error:
"Something went wrong, connection is closed"
If I put the host in maintenance mode it does not activate again and gives an error:
Operation Canceled
Error while executing action:
ovirt51.mydomain:
Cannot activate Host. Host has no unique id.
Resolved by reinstalling the host and checking to activate it. But it doesn't seem normal to me.
Please does anyone know how to resolve these issues?
Thank you.

Hosted engine installation oVirt 4.5 initialize lockspace volume
by lbayerlein＠lbayerlein.de
Hello,
hope, you are doing well. I try to install a new hosted engine on my environment to switch the storage this engine. I use following command to deploy the instance:
hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true

```
And I dont know, what is the reason. I zeroed the iscsi target, rebooted the hypervisor and updated all software packages.
```
[root@hypervisor01 ~]# rpm -qa|grep ovirt-host
ovirt-hosted-engine-setup-2.6.5-1.el8.noarch
ovirt-host-dependencies-4.5.0-3.el8.x86_64
ovirt-hosted-engine-ha-2.5.0-1.el8.noarch
ovirt-host-4.5.0-3.el8.x86_64
```
I tried the deployment without the ansible arguments. Unfortunately, the same error comes up. What can I do to solve this?
Thanks very much

Recreate engine without backup
by Igor Filipovic
Hi all,
I have a situation in which customer has deleted standalone engine completely (it was running on vmware), and all backups were saved on the same machine - so there is no backup available.
Can someone suggest how to preserve virtual machines which are still running on kvm hosts, and recreate standalone engine to be able to manage existing kvm hosts and machines? What could be scenario for this?
Thanks in advance and best regards!

Server 2008R2 UEFI ISO Boot Problerm
by Clint Boggio
Greetings oVirt team
I'm using "Version 4.5.7-0.master.20240327074810.git14bca0502d.el8 on CentOS Stream 9"
I have occasion to restore a windows backup image for the purpose of data extraction. To accomplish this I need to boot off a Server 2008R2 ISO. The machine to be restored was UEFI based originally and so it is required to be UEFI for the restoration process.
I seem to be having a problem with booting off of the ISO image in the required UEFI-based system. In pursuit of a solution I've read on some of the other forums about this same problem on other KVM-based platforms.
Booting that same ISO after changing the VM to BIOS works flawlessly. In the articles and threads I've read there is mention of hyper-v services that load during the guest boot process that are causing the ISO boot to hang.
Is it possible to disable (or is it even necessary to disable) "hv_time,hv_relaxed,hv_spinlocks=0x2000" in the "Custom Properties" section of the VM config ?
If any of you have some insight into this problem and a possible solution I'd appreciate the feedback.
