Announcing Oracle Linux Virtualization Manager Release 4.5

The Oracle Linux and Virtualization team is pleased to announce the 4.5 release of Oracle Linux Virtualization Manager. This release supports Oracle Linux 8 Kernel-based Virtual Machine (KVM) compute hosts and is based on the 4.5 release of the open source oVirt project. This server virtualization management platform can be easily deployed to configure, monitor, and manage an Oracle Linux KVM environment with enterprise-grade performance and support from Oracle.

In addition to the base virtualization management features required to operate your data center, notable features added with the Oracle Linux Virtualization Manager 4.5 release include:

  • Grafana integration: Enhanced reporting and monitoring of your infrastructure is available with the Grafana integration to the engine data warehouse. Use the default dashboards or create custom dashboards to monitor critical resources (data centers, clusters, hosts, VMs) and trend them over time.
  • Enhanced Oracle Linux 8 KVM host support: Oracle Linux Virtualization Manager users will run the more advanced versions of the KVM utilities (QEMU, Libvirt) that are available with Oracle Linux 8 KVM. The kvm_utils3 appstream module components offer higher performance and expanded support for the latest hardware.
  • Update to oVirt 4.5 release: The latest oVirt 4.5 release offers a number of enhancements and bug fixes over the oVirt 4.4 release.

New features

Oracle Linux Virtualization Manager 4.5 is based on the oVirt 4.5.4 open source software. Several new features are available with this upgrade release, including:

  • Snapshot enhancements: Multiple updates to better support backup and restore with live VM snapshots.
  • User Interface and usability updates:
    • A new search box for vNIC profiles was added to the browser user interface on the main vNIC profiles tab.
    • A confirmation prompt was added when suspending a virtual machine.
    • A new warning event is raised if the MAC Address Pool free and available addresses are below the set threshold.
    • A new warning is raised when the number of hosted-engine hosts exceeds the recommended maximum.
    • A new progress tracking status was added for Cluster Upgrades.
  • New cluster version: A new cluster-level 4.7 is now available and will be the default for new installs.
  • Distributed scheduling policy update: A new parameter was added to the evenly_distributed scheduling policy that takes into account the ratio between virtual and physical CPUs on the host.
  • Improvement to Storage Domains: Storage domains can now be deactivated and set to maintenance even if there are suspended VMs.
  • New delay parameter for console disconnect: A new user-specified delay parameter was added for the ‘Shutdown’ Console Disconnect Action of a VM.
  • Support for ovirt-engine-rename: The ovirt-engine-rename command has moved from a Technology Preview to a generally available and fully supported feature.

More information on these features can be found in the Oracle Linux Virtualization Manager Document Library, which has been updated for this release.  Visit the Oracle Linux Virtualization Manager Training website for videos, documents, and other useful links and further information on setting up and managing this solution.

Oracle Linux Virtualization Manager allows enterprise customers to continue supporting their on-premises data center deployments with the KVM hypervisor available on Oracle Linux 8 and the Unbreakable Enterprise Kernel Release 7.

Installation and Upgrades

Oracle Linux Virtualization Manager 4.5 can be installed from the Oracle Linux yum server or the Unbreakable Linux Network. Customers that have already deployed Oracle Linux Virtualization Manager 4.4 can upgrade to 4.5 using these same sites. Two new channels have been created in the Oracle Linux 8 repositories that users can access to install or update Oracle Linux Virtualization Manager:

  • oVirt 4.5 - base packages required for Oracle Linux Virtualization Manager

  • oVirt 4.5 Extra Packages - additional packages for Oracle Linux Virtualization Manager

Oracle Linux 8 hosts can be installed with installation media (ISO images) available from the Oracle Linux yum server or the Oracle Software Delivery Cloud. Step-by-step instructions to download the Oracle Linux 8 ISO can be found on the Oracle Linux Community website. Using the "Minimal Install" option during the installation process sets up a base KVM system, which will be updated using the KVM AppStream in the Oracle Linux 8 repositories. These KVM enhancements and other important packages for your Oracle Linux KVM host will be automatically installed.

Both Oracle Linux Virtualization Manager and Oracle Linux can be downloaded, used, and distributed free of charge and all updates and errata are freely available.

Support

Support for Oracle Linux Virtualization Manager is available to customers with an Oracle Linux Premier Support subscription. Refer to Oracle Linux Support for information about Oracle Linux support levels.
