oVirt 4.4.7 Release Notes

The oVirt Project is pleased to announce the availability of the 4.4.7 release as of July 06, 2021.

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 Red Hat Enterprise Linux 8.4 (or similar) and CentOS Stream.

NOTE

Starting from oVirt 4.4.6 both oVirt Node and oVirt Engine Appliance are based on CentOS Stream.

Please note that if you are upgrading oVirt Node from previous version you should remove CentOS Linux related yum configuration. See Bug 1955617 - CentOS Repositories should be removed from yum.repo.d when upgrading to CentOS Stream For more details.

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 4.4.7, see the release notes for previous versions.

Known issues

Workaround for: upgrade of oVirt Node to 4.4.7 from previous version breaks VM migration

It has been reported that upgrading to oVirt Node 4.4.7 breaks VM migration due to SELinux denials. For all the details please read [Bug 1979624] - imgbase should not copy selinux binary policy file. To workaround this, on each oVirt Node upgrade from previous versions please run as root:

semodule -B
touch /.autorelabel
reboot

How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1

Due to [Bug 1837864] - Host enter emergency mode after upgrading to latest build,

If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.7 you may get your host entering emergency mode.

In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts:

Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted).
Reboot.
Upgrade to 4.4.7 (redeploy in case of already being on 4.4.7).
Run vdsm-tool config-lvm-filter to confirm there is a new filter in place.
Only if not using oVirt Node:
- run “dracut –force –add multipath” to rebuild initramfs with the correct filter configuration
Reboot.

What’s New in 4.4.7?

Release Note

oVirt Engine WildFly

BZ 1938101 Rebase on Wildfly 23

oVirt Engine now requires WildFly 23

oVirt Engine Data Warehouse

BZ 1966574 Update the required Grafana to 7.3 in ovirt-dwh

Required Grafana version changed from 6.7 to 7.3.

oVirt Engine

BZ 1901011 [RFE] Remove Foreman integration from engine

Foreman integration, which allow to provision bare metal hosts from webadmin using Foreman and afterwards being added to engine, hasn’t been properly maintained for quite some time due to resource limitation and as there was no significant feedback from users about this feature, it was deprecated in oVirt 4.4.6 and now removed completely in oVirt 4.4.7.

Similar functionality to provision bare metal host can be achieved using Foreman directly and after that just add already provisioned host using webadmin or RESTAPI.

BZ 1804774 Simplify the process to add a msg on the RHVM Admin Portal Login

Adding a message to the welcome page is straight forward using a custom branding only containing a preamble section. An example of a preamble branding is https://bugzilla.redhat.com/attachment.cgi?id=1783329.

On an engine upgrade the custom preamble brand will remain in place and will work without issue.

During an engine backup and subsequent restore, on engine restore it is expected that the custom preamble branding will need to be manually restored/reinstalled and verified.

BZ 1950343 [RFE] Set compatibility level 4.6 for Default DataCenter/Cluster during new installations of oVirt 4.4.7

Default DataCenter/Cluster will be set to compatibility level 4.6 on new installations of oVirt 4.4.7
BZ 1966145 Remove version lock on specific ansible version and require ansible 2.9.z >= 2.9.21 in ovirt-engine

ovirt-engine in RHV 4.4.7 requires ansible 2.9.z higher than 2.9.20. Also in RHV 4.4.7 version for specific ansible version has been removed, because correct ansible version shipped in RHV channels.
BZ 1938101 Rebase on Wildfly 23

oVirt Engine now requires WildFly 23

ovirt-engine-extension-aaa-ldap

BZ 1964522 Allow both automatic detection of IP version available as well as manual configuration

To solve issues in mixed Pv4/IPv6 setups following changes has been done:

A new option pool.default.socketfactory.resolver.detectIPVersion

to enable/disable automatic detection of IP protocol has been

introduced:
- By default set to true
- Automatic detection of IP versions has been improved to use
  
  the default gateway IP addresses (if a default gateway has
  
  IPv4/IPv6 address, A/AAAA DNS records are used to resolve LDAP
  
  servers FQDNs)
- If automatic detection is disabled, then administrators need
  
  to set properly below options according to their network setup
A new option pool.default.socketfactory.resolver.supportIPv4

to enable/disable usage of IPv4 has been introduced:
- By default set to false (automatic detection is preferred)
- If set to true, type “A” DNS records are used to resolve LDAP
  
  servers FQDNs
Existing option pool.default.socketfactory.resolver.supportIPv6

is used to enable/disable usage of IPv6
- By default set to false (in previous versions it was enabled)
- If set to true, type “AAAA” DNS records are used to resolve
  
  LDAP servers FQDNs

So by default automatic detection of IP version using the default gateway addresses is used, which should work for most of the setups. If there is some special mixed IPv4/IPv6 setup, where automatic detection fails, then it’s needed to turn off automatic detection and configure IP versions manually as a part of /etc/ovirt-engine/aaa/<PROFILE>.properties configuration for specific LDAP setup.

Enhancements

oVirt Host Dependencies

BZ 1947450 ovirt-host shouldn’t have hard dependency on vdsm hooks

ovirt-host package now doesn’t pull in any vdsm-hook anymore.

Users now can decide if to install specific vdsm hooks or not.

oVirt Engine Data Warehouse

BZ 1948418 [RFE] Add memory, and CPU sizes to Hosts/Virtual Machines Trend dashboard

Feature:

added to hosts and vms trend dashboards 2 panels. one withe the total memory size, and one with the total cpu cores.

BZ 1849685 [RFE] Handle PKI renew for grafana

engine-setup now allows renewing the certificate also for grafana when it is set up on a separate machine from the engine.
BZ 1952424 [RFE] Add Data Source variable to all dashboards

Feature: Add the option to select Data Source for all dashboards.

Reason:

This way we can navigate easily if there are several different engines (with different dwh).

VDSM

BZ 1966177 [CBT][RFE] Unable to delete a vm checkpoint if vm has poweroff state

Feature:

VM checkpoint can be removed while the VM is in a ‘DOWN’ state.

Reason:

Until now, the VM checkpoint that was taken during a VM backup process can be removed only when the VM is running. This fix provides the ability to remove the VM checkpoint when the VM isn’t running using the same API -

DELETE /vms/123/checkpoints/456/

Result:

VM checkpoint can be removed when the VM is ‘UP’ or ‘DOWN’ using the same API.

BZ 1947450 ovirt-host shouldn’t have hard dependency on vdsm hooks

ovirt-host package now doesn’t pull in any vdsm-hook anymore.

Users now can decide if to install specific vdsm hooks or not.

oVirt Engine

BZ 1849861 [RFE][v2v] [upload/download disk/CBT] Failed to attach disk to the VM - disk is OK but image transfer still holds a lock on the disk

Feature:

Add 2 new backup phases:

SUCCEEDED
FAILED

Disable ‘vm_backups’ & ‘image_transfers’ DB tables cleanup after backup / image transfer operation is over.
Add DB cleanup scheduled thread to automatically clean backups and image transfers once in a while.

Reason:

After backup / image transfer operation finishes, all the execution data disappeared.

That means, that the user didn’t know the final execution state of the operation that was visible via DB and API while the backup / image transfer execution was still in progress.

In case of backup operation, the situation was even worse - there was no indication for success/failure, the last thing the user might be able to see is the ‘FINALIZING’ status.

We want the user to be able to see the operation result, but also not over-polute the database with too old data.

Result:

Added 2 new backup phases to show possible execution statuses (success/failure) for backup operations.
Cancel DB cleanup of the ‘vm_backups’ & ‘image_transfers’ DB tables when the backup / image transfer finishes to allow DB & API status retrieval by user.
Scheduled execution of the cleanup - 15 minutes for success entries, 30 minutes for the failure. Separate values for backup & for image transfer operations, an additional value for the cleanup thread rate (all 5 values are configurable).
Some minor user experience improvements.

BZ 1966177 [CBT][RFE] Unable to delete a vm checkpoint if vm has poweroff state

Feature:

VM checkpoint can be removed while the VM is in a ‘DOWN’ state.

Reason:

DELETE /vms/123/checkpoints/456/

Result:

VM checkpoint can be removed when the VM is ‘UP’ or ‘DOWN’ using the same API.

BZ 1913858 [RFE] Enable high-availability for VMs that are pinned to host(s)
BZ 1958081 [RFE] Enable ramfb for mdev with display=on

When a vGPU is used and nodisplay is not specified, an additional framebuffer display device is added to the VM now, allowing to display the VM console before the vGPU is initialized. This allows display console access during boot, instead of having just a blank screen there as before this change.

This works only on cluster levels >= 4.5. It is possible to disable the feature by setting VgpuFramebufferSupported Engine config value to false.

BZ 1953468 [CBT][RFE] Allow removing non-root checkpoints from the VM

Feature:

Allow removing any VM checkpoint from the checkpoint chain and not just the root checkpoint

Reason:

Users should be able to remove any checkpoint from the VM backups checkpoints chain.

Result:

Any checkpoint from the VM checkpoints chain can be removed and not just the root checkpoint in the chain.

oVirt Ansible collection

BZ 1959273 Add the option to pause Hosted-Engine deployment before running engine-setup

Feature: Allow to pause Hosted-Engine deployment before running engine-setup

Reason: This allows to make changes in the bootstrap VM

Result: Changes can be made on the Hosted-Engine VM during the deployment and before engine-setup

Deprecated Functionality

oVirt Engine Data Warehouse

BZ 1896359 “Count threads as cores” option is not honored by the RHV Dashboard CPU graph

In version 4.4.7.2 we will update the column name to number_of_threads.

In DWH we will leave the old name (threads_per_core) as another alias,

so DWH will have 2 columns with the same data: number_of_threads,threads_per_core.

In the next version we will completely delete the old name.

VDSM

BZ 1899875 drop support for VM-FEX

oVirt Engine

BZ 1896359 “Count threads as cores” option is not honored by the RHV Dashboard CPU graph

In version 4.4.7.2 we will update the column name to number_of_threads.

In DWH we will leave the old name (threads_per_core) as another alias,

so DWH will have 2 columns with the same data: number_of_threads,threads_per_core.

In the next version we will completely delete the old name.
