2 What's New

Release 4.5 of Oracle Linux Virtualization Manager is based on oVirt community release version 4.5.5.

Release 4.5.5 bug fixes and support for new features

  • Federal Information Processing Standard (FIPS) compliance support, which you can enable selectively, on specific VMs and bare metal machines, or across environment. For more information, see FIPS Mode Deployment in the Oracle Linux Virtualization Manager: Getting Started.

Release 4.5.4 bug fixes and support for new features

  • For added security, you can enable HTTP Strict Transport Security (HSTS). See Enabling HTTP Strict Transport Security in the Oracle Linux Virtualization Manager: Administration Guide.
  • Multiple updates to better support backup and restore with snapshots
  • Multiple user interface and usability improvements:
    • A new search box for vNIC Profiles was added oVirt Engine WebUI on the main vNIC profiles tab
    • A confirmation prompt was added when suspending a virtual machine
    • A new warning event is raised if 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
  • A new cluster-level 4.7 is now available. The 4.7 cluster level will be the default for new installs. Upgrades will carry forward the 4.4 cluster levels.
  • 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.
  • Storage domains can now be deactivated and set to maintenance even if there are suspended virtual machines.
  • A new user-specified delay parameter, Console Disconnect Action, was added for VNC console connections. This parameter defines what happens when the console is disconnected:

    • No action - No action is taken.

    • Lock screen (default) - For all Linux machines and for Windows desktops this locks the currently active user session. For Windows servers, this locks the desktop and the currently active user.

    • Logout user - For all Linux machines and Windows desktops, this logs out the currently active user session. For Windows servers, the desktop and the currently active user are logged out.

    • Shutdown virtual machine - Initiates a graceful virtual machine shutdown.

    • Reboot virtual machine - Initiates a graceful virtual machine reboot.

    This setting can be changed while the virtual machine is running but will not take effect until a new console connection is established.

The following technology preview features are tested and fully supported with this release:

  • Grafana integration: You can monitor your environment and display reports using Grafana dashboards that are based on data collected from the Data Warehouse database (ovirt_engine_history database). For more information, see Data Visualization with Grafana in the Oracle Linux Virtualization Manager: Architecture and Planning Guide.
  • The ovirt-engine-rename command (the oVirt Engine Rename Tool) which changes the fully-qualified DNS name of Oracle Linux Virtualization Manager.

Additional updates:

  • Support for the new kvm_utils3 appstream in the Oracle Linux 8 KVM Appstream Latest channel. This appstream delivers more advanced versions of QEMU and Libvirt.
  • Many of the third-party packages and other RPMs

For Requirements and Scalability Limits, see the Oracle Linux Virtualization Manager: Architecture and Planning Guide.
