oVirt 4.5.2 Release Notes

The oVirt Project is pleased to announce the availability of the 4.5.2 release as of August 10, 2022.

oVirt is a free open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.

This release is available now for CentOS Stream 8 and Red Hat Enterprise Linux 8.6 (or similar).

To find out how to interact with oVirt developers and users and ask questions, visit our community page. All issues or bugs should be reported via Red Hat Bugzilla.

If you’d like to try oVirt as quickly as possible, follow the instructions on the Download page.

For complete installation, administration, and usage instructions, see the oVirt Documentation.

For a general overview of oVirt, read the About oVirt page.

To learn about features introduced before 4.5.2, see the release notes for previous versions.

IMPORTANT If you are going to install on RHEL 8.6 or derivatives please follow Installing on RHEL first.

What’s New in 4.5.2?

Release Note

oVirt Engine

BZ 2107250 Upgrade of the host failed as the oVirt 4.3 hypervisor is based on RHEL 7 with openssl 1.0.z, but oVirt Engine 4.4 uses the openssl 1.1.z syntax

Process to check certificate validity has been changed to be compatible with both RHEL 8 and RHEL 7 based hypervisors
BZ 2097560 Warning when ovsdb-server certificates are about to expire(engine certificate)

Expiration of ovirt-provider-ovn certificate is now checked regularly along with other oVirt certificates (such as engine CA, engine or hypervisors) and if ovirt-provider-ovn is going to expire or already expired, the warning or alert is being raised into audit log. To renew ovirt-provider-ovn certificate administators need to run engine-setup.

If your ovirt-provider-ovn certificate expires on previous oVirt version, please upgrade to oVirt 4.5 batch 2 or newer, and ovirt-provider-ovn certificate will be renewed automatically as a part of engine-setup
BZ 2104408 /var/cache/dnf fills up and will cause upgrades to fail

yum cache is now cleared always before upgrading a host to minimize issues with filling up available space in /var/tmp
BZ 2090645 Host stuck in state ‘Connecting’ when certificates expire

Host should move to NonResposive status when VDSM certificate expires.
BZ 2096523 Failed to run “Check for Upgrade”

It’s now possible to install and upgrade hypervisors using non-standard SSH port

Enhancements

VDSM

BZ 1793207 [RFE] Notify if multipath User Friendly Names are used

Feature: Protect users from using wrong multipath configuration by parsing the configuration in vdsm-tool, look for user_friendly_names setting occurrences, and print a warning if enabled. Reason: It is not supported to use multipath User Friendly Names(UFN) on oVirt hosts, but it is not enforced either. It may cause corruption in block SDs if a host is running with UFN enabled. Result: $ vdsm-tool is-configured –module multipath WARNING: Invalid configuration: ‘user_friendly_names’ is enabled in multipath configuration: section1 { key1 value1 user_friendly_names yes key2 value2 } section2 { user_friendly_names yes } This configuration is not supported and may lead to storage domain corruption.
