Recombining disks under a single VM
by Matthew.Stier＠fujitsu.com
Up until now, we've been using iSCSI as the storage on all of our datacenters, and when we need to bulk move VMs, we moved iSCSI storage domains.
We've just setup our first datacenter with Fiber Channel storage, and no connectivity to our iSCSI storage. For this move we have fallen back to using NFS storage domains, to move the necessary VMs from datacenter ONE to datacenter TWO.
The bulk of the transfer went fine, but for about one dozen two disk VMs both disks did not get moved at the same time. So now I have one dozen VMs with only one drive on datacenter TWO and the other drive as an un-importable VM on the NFS storage partition, mounted on datacenter TWO.
Any hints on how I "merge" these two, back into one function VM?

Migrating to keycloak
by eric.j.gillingham＠jpl.nasa.gov
I have an existing ovirt cluster, and I'm trying to migrate it from the internal sso and LDAP over to keycloak but am kind of at a loss.
I followed the Activation procedures on https://github.com/oVirt/ovirt-engine-keycloak/blob/master/keycloak_usage... and am able to login to the keycloak console fine, but when I try to access the ovirt-engine admin panel I just get an internal server error.
httpd log contains "oidc_util_json_string_print: oidc_util_check_json_error: response contained an "error" entry with value: ""Realm does not exist"""
Does engine-setup not configure the keycloak it creates with the proper configuration for ovirt? The apache config seems to have some password and other settings for oidc, so that end got configured, but not the keycloak side. There's no ovirt-engine or other ovirt related clients inside the newly created keycloak.

centos-stream-release-8.6-1.el8.noarch vs redhat-release-8.7-0.3.el8.x86_64
by eshwayri＠gmail.com
What is the best way to resolve the below error. All other EL8 packages are now at 8.7. (--nobest) but the release file(s) aren't updating because this package won't upgrade. The blocking centos-stream-release-8.6-1.el8.noarch package is a pre-req for all the oVirt files, so I can't remove it. I suspect all oVirt is using from it are the repos. Do I force install redhat-release-8.7-0.3.el8.x86_64? Is there a way to do that?

After failed upgrade from 4.5.1 to 4.5.3, upgrades do not show up anymore
by Gianluca Amato
Hi all,
I recently tried to upgrade an oVirt node from 4.5.1 to 4.5.3. The upgrade failed (I have no idea idea why... how can I access the installation logs?). The node is still working fine running the old 4.5.1 release, but now the oVirt web console says that it is up to date and it does not let me retry the upgrade. However, I am still on version 4.5.1, as witnessed by the result of "nodectl info":

------
Comparing the situation with other hosts in the same data center, it seems that the problem is that the package ovirt-node-ng-image-update-placeholder is not installed anymore, hence "dnf upgrade" has nothing to do. My idea was to manually download and install the 4.5.1 version of ovirt-node-ng-image-update-placeholder and attempt installation again.
Is it a correct way to proceed ?
Thanks for any help.

el9 official use?
by Nathanaël Blanchet
Hello,
Until 4.5.4, el9 ovirt-node was for testing. Following 4.5.4 releases note, it seems to be officially supported but there is no information about el9 engine support.
What about it?

Max network performance on w2019 guest
by Gianluca Cecchi
One customer sees 2,5gbs on 10gbs adapters for w2019 VM with virtio using
iperf3.
Instead with Oracle linux 8 VMS of the same infra sees 9gbs.
What is the expected maximum on windows with virtio based on experience?

State sync
by KSNull Zero
Hello!
Is there any way to "sync" current host/datastore/vm state after Engine restore from backup ?
For example - let's say we have a backup made 3 hour later from current time and in this 3 hours we made some changes to vm (change config/power state/take snapshots for example) or hosts (enter maintenace mode, network changes and so on).
If we restore backup we did not see those changes because all of the info is stored in the engine database.
So the question - is there any way to get "synced" with current actual infrastructure/vm state ?
Thank you.

oVirt Update Errors
by Matthew J Black
Hi Guys,
Attempting to do a Cluster update via the oVirt GUI and I'm getting the following errors (taken from the logs) which I've confirmed via a straight `dnf update`:
Problem 1: package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch conflicts with ansible-core >= 2.13 provided by ansible-core-2.13.3-1.el8.x86_64
- cannot install the best update candidate for package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch
- cannot install the best update candidate for package ansible-core-2.12.7-1.el8.x86_64
Problem 2: problem with installed package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch
- package ovirt-hosted-engine-setup-2.6.6-1.el8.noarch conflicts with ansible-core >= 2.13 provided by ansible-core-2.13.3-1.el8.x86_64
- package ovirt-ansible-collection-3.0.0-1.el8.noarch requires ansible-core >= 2.13.0, but none of the providers can be installed
- cannot install the best update candidate for package ovirt-ansible-collection-2.3.0-1.el8.noarch
Is it OK to do a `dnf update --nobest` or a `dnf update --allowerasing` on each host, or is there some other solution that I'm missing?
Cheers
