oVirt 4.4.0 Alpha release refresh is now available for testing


The oVirt Project is excited to announce the availability of the alpha release refresh of oVirt 4.4.0 for testing, as of March 6th, 2020


This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3.


Important notes before you try it

Please note this is an Alpha release.

The oVirt Project makes no guarantees as to its suitability or usefulness.

This pre-release must not to be used in production, and it is not feature complete.

In particular, please note that upgrades from 4.3 and future upgrades from this alpha to the final 4.4 release from this version are not supported.

Although, I successfully managed to upgrade my el7 4.3 engine to 4.4 a few weeks ago... do it means it is not feasable anymore.

Some of the features included in oVirt 4.4.0 Alpha require content that will be available in CentOS Linux 8.2 which are currently included in Red Hat Enterprise Linux 8.2 beta. If you want to have a better experience you can test oVirt 4.4.0 Alpha on Red Hat Enterprise Linux 8.2 beta.


Known Issues

  • After installation open the Default cluster and hit “Save”, for any other new Cluster using CPU autodetection the dialog needs to be explicitly saved after the detection happens, after first host is added. (bug https://bugzilla.redhat.com/1770697)

Installation instructions


For the engine: either use appliance or:

- Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x86_64-dvd1.iso

An el7 for the engine was required with the first alpha releases, so it means that final 4.4 won't support el7 anymore for engine?

- dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm

- dnf update (reboot if needed)

- dnf module enable -y javapackages-tools pki-deps 389-ds

- dnf install ovirt-engine

- engine-setup


For the nodes:

Either use oVirt Node ISO or:

- Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x86_64-dvd1.iso ; select minimal installation

- dnf config-manager --set-enabled PowerTools

- dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm

- dnf update (reboot if needed)

- Attach the host to engine and let it be deployed.


What’s new in oVirt 4.4.0 Alpha?


  • Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts

  • Easier network management and configuration flexibility with NetworkManager

  • VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware

  • Support for direct passthrough of local host disks to VMs

  • Live migration improvements for High Performance guests.

  • New Windows Guest tools installer based on WiX framework now moved to VirtioWin project

  • Dropped support for cluster level prior to 4.2

  • Dropped SDK3 support

  • 4K disks support

  • Exporting a VM to a data domain

  • Editing of floating disks

  • Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine

  • Adding/reinstalling hosts are now completely based on Ansible

  • The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead


This release is available now on x86_64 architecture for:

* Red Hat Enterprise Linux 8.1 or newer

* CentOS Linux (or similar) 8.1 or newer


This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for:

* Red Hat Enterprise Linux 8.1 or newer (8.2 beta recommended)

* CentOS Linux (or similar) 8.1 or newer

* oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only)


See the release notes [1] for installation instructions and a list of new features and bugs fixed.


If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ.

In such a case, please be sure  to take the qc2 image and not the ova image.


Notes:

- oVirt Appliance is already available for CentOS Linux 8

- oVirt Node NG is already available for CentOS Linux 8
