Chapter 6. Release Information

These release notes highlight technology preview items, recommended practices, known issues, and deprecated functionality to be taken into consideration when deploying this release of Red Hat Virtualization.

Notes for updates released during the support lifecycle of this Red Hat Virtualization release will appear in the advisory text associated with each update or in the Red Hat Virtualization Technical Notes. This document is available on the Red Hat documentation page.

6.1. Red Hat Virtualization 4.4 SP 1 Batch Update 2 (ovirt-4.5.2)

6.1.1. Bug Fix

These bugs were fixed in this release of Red Hat Virtualization:

BZ#1853924
Previously, when attempting to add a disk using ovirt-engine SDK script when the disk already exists, the operation fails, and an exception is thrown. With this release, the Add Disk Functionality checks for duplicate disks, and fails gracefully with a readable error message when the disk to be inserted already exists.
BZ#1955388
Previously, the Manager was able to start a virtual machine with a Resize and Pin NUMA policy on a host whose physical sockets did not correspond to the number of NUMA nodes. As a result, the wrong pinning was assigned to the policy. With this release, the Manager does not allow the virtual machine to be scheduled on such a host, making the pinning correct based on the algorithm.
BZ#2081676
Previously, when two mutually exclusive sos report options were used in the ovirt-log-collector, the log size limit was ignored. In this release, the limit on the size of the log per plugin works as expected.
BZ#2097558
Previously, running engine-setup did not always renew OVN certificates when they were close to expiration or expired. With this release, OVN certificates are always renewed by engine-setup when needed.
BZ#2097725
Previously, the Manager issued warnings about approaching certificate expiration before engine-setup could update the certificates. In this release the expiration warning and certificate update periods are aligned, and certificates are updated as soon as the warnings about their upcoming expiration occur.
BZ#2101481
The handling of core dumps during upgrade from previous Red Hat Virtualization versions to RHV 4.4 SP1 batch 1 has been fixed.
BZ#2104115
Previously, when importing a virtual machine with manual CPU pinning (pinned to a dedicated host), the manual pinning string was cleared, but the CPU pinning policy was not set to NONE. As a result, importing failed. In this release, the CPU pinning policy is set to NONE if the CPU pinning string is cleared, and importing succeeds.
BZ#2105781
The hosted-engine-ha binaries have been moved from /usr/share to /usr/libexec. As a result, the hosted-engine --clean-metadata command fails. With this release, you must use the new path for the command to succeed: /usr/libexec/ovirt-hosted-engine-ha/ovirt-ha-agent
BZ#2109923
Previously, it was not possible to import templates from the Administration Portal. With this release, importing templates from the Administration Portal is now possible.

6.1.2. Enhancements

This release of Red Hat Virtualization features the following enhancements:

BZ#1793207

A new warning has been added to the vdsm-tool to protect users from using the unsupported user_friendly_names multipath configuration. The following is an example of the output:

$ 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.
BZ#2097536
In this release, the rhv-log-collector-analyzer now provides a detailed output for each problematic image, including disk names, associated virtual machine, the host running the virtual machine, snapshots, and the current Storage Pool Manager. This makes it easier to identify problematic virtual machines and collect SOS reports for related systems. The detailed view is now the default, and the compact option can be set by using the --compact switch in the command line.
BZ#2097560
Expiration of ovirt-provider-ovn certificate is now checked regularly along with other RHV certificates (engine CA, engine, or hypervisors) and if ovirt-provider-ovn is going to expire or has expired, the warning or alert is raised to the audit log. To renew the ovirt-provider-ovn certificate, run engine-setup. If your ovirt-provider-ovn certificate expires on a previous RHV version, you must upgrade to RHV 4.4 SP1 batch 2 or newer, and the ovirt-provider-ovn certificate will be renewed automatically as part of engine-setup.
BZ#2104939
With this release, OVA export or import works on hosts with a non-standard SSH port.
BZ#2107250
With this release, the process to check certificate validity is now compatible with both RHEL 8 and RHEL 7 based hypervisors.

6.1.4. Rebase: Bug Fixes Only

These items are rebases of bug fixes included in this release of Red Hat Virtualization:

BZ#2104831

6.1.5. Release Notes

This section outlines important details about the release, including recommended practices and notable changes to Red Hat Virtualization. You must take this information into account to ensure the best possible outcomes for your deployment.

BZ#2049286
With this release, only virtual machines pinned to hosts selected for upgrade are stopped during cluster upgrade. VMs pinned to hosts that are not selected for upgrade are not stopped.
BZ#2108985
RHV 4.4 SP1 and later is only supported on RHEL 8.6, so you cannot use RHEL 8.7 or later, and must stay with RHEL 8.6 EUS.
BZ#2113068
With this release, permissions for the /var/log/ovn directory are updated correctly during the upgrade of OVS/OVN 2.11 to OVS 2.15/OVN 2021.

6.1.6. Deprecated Functionality

The items in this section are either no longer supported, or will no longer be supported in a future release.

BZ#2111600
ovirt-engine-extension-aaa-jdbc and ovirt-engine-extension-aaa-ldap are deprecated in RHV 4.4 SP1. They remain in the RHV product, but for any new request, you should use integration with Red Hat Single Sign-On as described in https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html-single/administration_guide/index#Configuring_Red_Hat_SSO
