Weirdness with attempting NFS mount
by Michaal R
I'm attempting to mount a share from a TrueNAS server in oVirt through the Storage > Storage Domains UI as a New Domain. Whenever I try to add the domain (as server:share), it kicks back a Permission Denied error. Looking at the vdsm.log file, I see the below snippet:

Stepping it through, am I correct that I'm seeing vdsm not able to create the local directory for the NFS mount? It previously was able to mount an NFS share from the host to itself when I initially setup the server for testing.
When I do an ls -l on the directory it's trying to create the mount point in, I see ownership looks correct.
[root@ovirt ~]# cd /rhev/data-center/
[root@ovirt data-center]# ls
c7d57de0-6ba8-11ee-9a48-00163e1989b9 mnt

Is there something missing? Something that got misconfigured, maybe? Or something I can configure to fix this?

oVirt host locked in installing status
by Michele la Torre
Hi all,
I have an oVirt installation (version 4.5.4-1.el8) with the engine installed in standalone mode. One of the hosts, after encountering some issues with the certificate renewal (which have now been resolved, and there are no current errors related to this), is stuck in the "Installing" state.
I've checked the logs, but there are no errors reported. Do you have any ideas on what I can try to resolve this?
Best regards,
Michele

obtain direct LUN wwid in the guest
by LS CHENG
Hi all
I am working with Oracle Linux Virtualization Manager 4 (OLVM) which is
based on ovirt.
When I worked with OLVM 3 and when assigning direct lun to the guests in
the guest I could obtain LUN's wwid with this command
/usr/lib/udev/scsi_id -g -u -d /dev/sdc1
36000c29f1382ae964d67392dfdfaaf0f
similar to VMWare's disk.EnableUUID
But now in OLVM 4 I am getting this in the guest which is not LUN's wwid
/usr/lib/udev/scsi_id -g -u -d /dev/sdc
0QEMU_QEMU_HARDDISK_671b475e-98ab-4f3b-a23d-2f8eed964e92
I wonder if is it possible to get LUN's wwid in the guest in OLVM 4?
Thanks1

/etc/pki/ovirt-engine/ca.pem is not on a local filesystem
by nicolas＠devels.es
Hi,
We're running oVirt 4.5.4, recently we got this alert:
Engine's certification is about to expire at 2023-11-19. Please renew
the engine's certification.
So I'm trying to run:
engine-setup --offline
However, it fails with the following error:

Ovirt 4.3 console.vv
by eevans＠digitaldatatechs.com
I have CentOS Stream 9 on my laptop with KDE Plasma Workspaces.
I installedd virt-viewer and tried through gui, console and it tells me the virtual machine can't be found.
It works fine with the Windows viewer. It seems to be a Centos issue. Something is not reading or interuppreting the file properly.
I'd like to get this resolved.
I hope someone has an answer.
Thanks in advance.

by dominic.gwerder＠bits.ch
Hi
I'm trying to replace the old certificate of the engine, so tha I can again access the management console. I've been reading thorugh a lot of articels and threads and the easiest solution, should be by running the engine-setup. I always get the following error:
[ INFO ] Creating CA: /etc/pki/ovirt-engine/ca.pem
[ ERROR ] Failed to execute stage 'Misc configuration': Command '/usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh' failed to execute
How can I fix this?
Thanks in advance for any help!

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?

Engine on EL 9
by David Carvalho
Hello, good morning.
I’m using Oracle Linux and I intended to install a virtualization platffom with KVM and oracle VM. The Oracle documention only mentions Oracle Linux 8 and there are no oVirt repositories available for OL 9.
I visited ovirt.org site and at the download page it only mentions:
Engine:
* Red Hat Enterprise Linux 8.7 (or similar)
* CentOS Stream 8
I still had no reply at Oracle foruns. Will there be a possibility to use this with Oracle Linux 9 soon?
I have 3 servers to install and I also intend to use Gluster FS.
Thanks and regards.
Os melhores cumprimentos

VMs randomly pause due to unknown storage error, unable to resume
by Jon Sattelberger
Hi,
> VM xxx has been paused due to unknown storage error.
> Migration failed due to a failed validation: [Migrating a VM in paused status due to I/O error is not supported.] (VM: xxx, Source: yyy).
Up until recently oVirt 4.5.4 has been running fine on our RHEL 8 hypervisors with primarily (and a few appliances) Linux guests. We started to add Windows 2019 VMs to the cluster with the guest agent installed. They seem to run fine at first, but some of the Windows VMs may randomly pause due to an unknown storage error. The VM cannot be resumed through the UI or virsh. The paused VM cannot be migrated to another Hypervisor. The GlusterFS storage volumes seem fine. Resetting the VM seems to work, but eventually it'll become paused again. The only thing that came to my mind is the virtual hard disks are thin provisioned. Is a preallocated disk necessary for Windows VMs? Any helpful hints on where to look next is greatly appreciated.
Thank you,
Jon
