ovirtmgmt claims no defroute after RHEL upgrade from 8.10 to 9.5
by Austin Coppock
First off apologies, I am unable to post log files as my oVirt servers have no access to the Internet.
I have several oVirt clusters, all were running oVirt 4.5 on RHEL 8.10. I am in the process of upgrading them to RHEL 9.5. with a few minor updates of oVirt packages. The steps I used to do this are:
• Backup up the standalone engine DB
• Rebuild the engine to RHEL 9.5, reinstall oVirt, restore the DB
• Log back in to the engine, place first hypervisor into maintenance and rebuild to RHEL 9.5.
• Remove old hypervisor via the engine GUI and add back in to the cluster
• Repeat for each hypervisor until all are upgraded.
This has worked perfectly, everything seems to be normal, but I then noticed that if I select the “Network Interfaces” tab on a hypervisor it shows my bonded interface as “Out-of-sync”, clicking the “Sync All Networks” does nothing.
If I click on “Setup Host Networks” and hover the mouse over the ovirtmgmt interface I see the message “Default Route. Host: false DC: true”
If I run the command “vdsm-client Host getNetworkCapabilities” on the hypervisor, it shows that the {bridges: ovirtmgmt: ipv4defaultroute false} and {networks: ovirtmgmt: ipv4defaultroute false } on my clusters that are still on RHEL 8.10 the above command shows ipv4defaultroute true.
Running the command “ip route show” shows that my default route IS on device ovirtmgmt
I am not experiencing any network issues, but getting rid of this out-of-sync message would be nice.
Is this a bug or a bad status issue? Or do I have some obscure setting not correct?
For both RHEL 8.10 and RHEL 9.5 builds we have used Ansible to perform the tasks, (with minor tweaks). So, the same procedure has been used for both.

additional language
by ebugaev＠itkey.com
Are there instructions on how to add an additional language to ovirt-engine?
What needs to be done so that an additional language appears in the language selection list on the main page of the engine?

Renewal of VDSM certificate in one node cluster
by ikbal.charen＠kepler-technologies.com
Hello,
I have a single-node cluster running Hosted Engine, version 4.4.10. While I'm able to renew the engine certificate, I'm unable to renew the VDSM certificate because I cannot put the host into maintenance mode (since it is running the Hosted Engine VM). What steps can I take to resolve this?
Best regards,

Host reboot take an awful lot of time
by duparchy＠esrf.fr
KVM host is upgraded then rebooted. It seems OK (ssh available, no particular activity) but it takes an awful lot of time for the manager to acknowledge it and let us activating the host.
This makes the upgrade process of a whole infrastructure (several hosts) very very long.
Is it just us ? (oVirt 4.5 "Oracle" flavor)

Help With CPU Type
by Daniel Martins
Hi There,
Please may you assist me with the below?
I need to remove an oVirt host within a cluster that is using CPU Type Intel Westmere IBRS SSBD Family. Once the host is removed i need to change the CPU type to Intel Broadwell which the remaining hosts Use.
So my question is will there need to be down time on the Virtual machines to change this?

Managing Users with Keycloak WebUI
by Vladislav Solovei
Hello! I have a question about managing users through the Keycloak WebUI. With oVirt 4.5.
Can I do this? Is it the right approach? Or should I avoid doing it? For example, if I want to create a user with 2FA (OTP)
