The release of oVirt 4.5.0 has been announced, based on the KVM hypervisor and the libvirt library for deploying, maintaining, and monitoring virtual machines and managing cloud infrastructure. The technologies developed in oVirt for virtual machine management are used in the Red Hat Enterprise Virtualization product and can serve as an open alternative to VMware vSphere. In addition to Red Hat, companies like Canonical, Cisco, IBM, Intel, NetApp, and SUSE also participate in the development. The project's code is distributed under the GPLv2 license. Ready-to-use packages are available for CentOS Stream 8 and Red Hat Enterprise Linux 8.6 Beta. A deployable ISO image of oVirt Node NG, based on CentOS Stream 8, is also available.
oVirt is a stack that encompasses all levels of virtualization—from the hypervisor to the API and GUI interface. Although the primary hypervisor in oVirt is positioned as KVM, the interface is implemented as an abstraction layer over the libvirt library, which is independent of the hypervisor type and suitable for managing virtual machines based on various virtualization systems, including Xen and VirtualBox. oVirt includes a framework for rapid mass creation of highly available of virtual machines with support for live migration of environments between servers without downtime.
The platform provides tools for creating dynamic load balancing rules and managing cluster resources, mechanisms for managing cluster power consumption, tools for managing virtual machine images, and components for converting and importing existing virtual machines. A unified virtual data storage is supported, accessible from any node. The interface includes an advanced reporting system and administration tools that allow management of the configuration at both the infrastructure level and the individual virtual machine level.
The most notable innovations include:
- Support for CentOS Stream 8 and RHEL 8.6 Beta has been provided.
- Experimental support for CentOS Stream 9 has been implemented.
- Updated versions of the components used, including GlusterFS 10.1, RDO OpenStack Yoga, OVS 2.15, and Ansible Core 2.12.2.
- Built-in support for IPSec for hosts with the OVN (Open Virtual Network) virtual network and the configured ovirt-provider-ovn package has been implemented.
- Support for the Virtio 1.1 specification has been added.
- The ability to enable NVIDIA Unified Memory technology for virtual GPUs (mdev vGPU) has been provided.
- Export to OVA (Open Virtual Appliance) has been accelerated using NFS.
- A search function has been added to the vNIC profiles tab in the web interface.
- Improved notification regarding the upcoming deprecation of certificates.
- Support for Windows 2022 has been added.
- The nvme-cli package has been included in the host composition.
- Automatic binding of CPU and NUMA during migration has been ensured.
- The ability to switch storage to maintenance mode with virtual machine freeze has been provided.
- Nine vulnerabilities have been eliminated, eight of which have been assigned a moderate level of severity, and one a low level. Most issues concern cross-site scripting (XSS) in the web interface and denial of service in the regular expression handler.
