Announcing Oracle Linux Virtualization Manager 4.3

John Priest
Director of Product Management

Oracle is pleased to announce the general availability of Oracle Linux Virtualization Manager, release 4.3. This server virtualization management platform can be easily deployed to configure, monitor, and manage an Oracle Linux Kernel-based Virtual Machine (KVM) environment with enterprise-grade performance and support from Oracle. This release is based on the 4.3.6 release of the open source oVirt project.

New Features with Oracle Linux Virtualization Manager 4.3

In addition to the base virtualization management features required to operate your data center, notable features added with the Oracle Linux Virtualization Manager 4.3 release include:

  1. Self-Hosted Engine: The oVirt Self-Hosted Engine is a hyper-converged solution in which the oVirt engine runs on a virtual machine on the hosts managed by that engine. The virtual machine is created as part of the host configuration, and the engine is installed and configured in parallel to the host configuration process. The primary benefit of the Self-Hosted Engine is that it requires less hardware to deploy an instance of the Oracle Linux Virtualization Manager as the engine runs as a virtual machine, not on physical hardware. Additionally, the engine is configured to be highly available. If the Oracle Linux host running the engine virtual machine goes into maintenance mode, or fails unexpectedly, the virtual machine will be migrated automatically to another Oracle Linux host in the environment.
  2. Gluster File System 6.0: oVirt has been integrated with GlusterFS, an open source scale-out distributed filesystem, to provide a hyper-converged solution where both compute and storage are provided from the same hosts. Gluster volumes residing on the hosts are used as storage domains in oVirt to store the virtual machine images. Oracle Linux Virtualization Manager is run as the Self Hosted Engine within a virtual machine on these hosts. GlusterFS 6.0 is released as an Oracle Linux 7 program.
  3. Virt-v2v: The virt-v2v tool converts a single guest from another hypervisor to run on Oracle Linux KVM. It can read Linux and Windows Virtual Machines running on Oracle VM or other hypervisors, and convert them to KVM machines managed by Oracle Linux Virtualization Manager.
  4. New guest OS support: Oracle Linux Virtualization Manager guest operating system support has been extended to include Oracle Linux 8, Red Hat Enterprise Linux 8, CentOS 8, SUSE Linux Enterprise Server (SLES) 12 SP5 and SLES 15 SP1.
  5. oVirt 4.3 features and bug fixes:
    • Improved performance when running Windows as a guest OS. Included with this release are the latest Oracle VirtIO Drivers for Microsoft Windows.
    • Higher level of security with TLSv1 and TLSv1.1 protocols now disabled for vdsm communications.
    • Numerous engine, vdsm, UI, and bug fixes.

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, 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-premise data center deployments with the KVM hypervisor available on Oracle Linux 7 Update 7 with the Unbreakable Enterprise Kernel Release 5. This 4.3 release is an update release for Oracle Linux Virtualization Manager 4.2.

Getting Started

Oracle Linux Virtualization Manager 4.3 can be installed from the Oracle Linux yum server or the Oracle Unbreakable Linux Network. Customers that have already deployed Oracle Linux Virtualization Manager 4.2 can upgrade to 4.3 using these same sites. Two new channels have been created in the Oracle Linux 7 repositories that users will access to install or update Oracle Linux Virtualization Manager:

  • oVirt 4.3 - base packages required for Oracle Linux Virtualization Manager
  • oVirt 4.3 Extra Packages - additional packages for Oracle Linux Virtualization Manager

Oracle Linux 7 Update 7 hosts can be installed with installation media (ISO images) available from the Oracle Software Delivery Cloud. Step-by-step instructions to download the Oracle Linux 7 Update 7 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 can then be updated using the KVM Utilities channel in the Oracle Linux 7 repositories. These KVM enhancements and other important packages for your Oracle Linux KVM host can be installed from the Oracle Linux yum server and the Oracle Unbreakable Linux Network:

  • Latest - Latest packages released for Oracle Linux 7
  • UEK Release 5 - Latest Unbreakable Enterprise Kernel Release 5 packages for Oracle Linux 7
  • KVM Utilities - KVM enhancements (QEMU and libvirt) for Oracle Linux 7
  • Optional Latest - Latest optional packages released for Oracle Linux 7
  • Gluster 6 Packages - Latest Gluster 6 packages for Oracle Linux 7

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.

    Hello John,

    If I understand it correctly, DB19c is the only product that is officially supported to run on the OLVM platform. When do you expect other Oracle products such as the EBS suite to become certified? Currently, OLVM is not listed as a virtualization platform on the certification tab in Oracle Support.

    Thank you,
    Onno van der Poel
  • Wayne Pugsley Tuesday, April 7, 2020
    Fantastic, we have been waiting for this. Is it supported as an installation option on OCI Bare Metal?
  • john priest Tuesday, April 7, 2020
    Hi Onno,
    DB is one of the few application teams that do certify down to the hypervisor layer. And in addition to 19c, 18c and 12cR1 are on the latest certification list with Oracle Linux KVM.
    Other applications like Fusion Middleware test to the guest OS level and also support the OS in a virtualized environment. I will confirm the same with the EBS team
  • john priest Tuesday, April 7, 2020
    Hi Wayne,
    We are looking into this option.
    Please get in touch with me directly or reach out to the partner team to discuss your use case further.

  • Antoine Bonello Thursday, April 16, 2020
    is there an option to upgrade from OLVM 4.2.8 to OLVM 4.3.6 ? And if so, can you please provide documentation link.

  • john priest Thursday, April 16, 2020
    Hi Antoine,

    Thanks for the message.

    Yes, there is an upgrade option from OLVM 4.2.8 to OLVM 4.3.6. The best starting point in the documentation is here: https://docs.oracle.com/en/virtualization/oracle-linux-virtualization-manager/getstart/engine-upgrade.html

    Let us know if you need anything else.

  • Andrea De Angelis Monday, April 27, 2020

    there are any guide to move from OVM 3.4.6 to Oracle LVM 4.3?
    Another question the support matrix is the same?

    Many Thanks
  • Jalal Tuesday, April 28, 2020
    indeed I have an internship at the university the subject I have to deal with is implemented an oracle linux virtualization platform.
    I would like to have documents concerning this project with a comparison with the proxmox tool the advantages of olvm compared to proxmox what I need as equipment for the implementation of the project
    the limit of olvm
  • john priest Tuesday, April 28, 2020
    All of the OLVM Docs can be found here:
    And some good training videos here:
    Hope this helps you get OLVM installed and to build your comparison.
  • john priest Tuesday, April 28, 2020
    Hi Andrea,
    You can check out the migration document here:
    Oracle VM and Oracle Linux KVM/OLVM are separate products covered under the OVM or OL lifecycle documents.
  • Bug report Sunday, May 3, 2020
    Hi dear John,
    Is thre any wayt to report Bugs related to OLVM - 4.3?
    We are currently getting this problem aredy report into Redhat Bugzilla
  • john priest Monday, May 4, 2020
    Yes, Oracle Support is available and will be able to help. Please contact them at http://support.oracle.com/ or from Brazil you can call Toll Free: 0800.891.5899 or +55.11.5189.1001
  • Wendy Thursday, May 21, 2020
    Hi John,
    Is there a security whitepaper available for Oracle Linux KVM similar to what is available for OVM? Or a security hardening guide focused on KVM?
  • john priest Friday, May 22, 2020
    Hi Wendy,

    We do have a Security Guide for Oracle Linux 7:
    Take a look at this and I will connect with you directly to follow-up.

  • Luca Wednesday, May 27, 2020
    Hi John,
    I have a question on supported database release on oracle KVM vm's. can i run only 12r1 ,18c and 19c?
    Oracle database is only certificated on linux 7 on kvm guest?
  • Simon Friday, June 5, 2020
    Hi Luca,

    actually Oracle Database releases certified to run on top of Oracle Linux KVM are 12cR1, 18c and 19c.
    That said, for the OS release you can check the Oracle Database documentation.

  • Jose Angel Friday, August 14, 2020
    Hello John,

    GlusterFS are used as storage domains to store the virtual machine images.

    Is it also possible to connect to the GlusterFS from VMs to use as storage by the processes?
  • Simon Monday, September 7, 2020
    Hi Jose Angel,

    technically is possible and feasible (by iSCSI or NFS) but what is the use-case ?
    Getting your VM virtual-disks created and presented to the VM could be easier.

  • Jose Angel Thursday, September 10, 2020
    Hi Simon,

    The use case is to take advantage of the GlusterFS configured to OVLM, to create additional volumes for store the files of some applications, instead of configure a second GlusterFS.

    The question is whether creating additional volumes in the same GlusterFS used by OVLM, can create problems for OVLM.

    Than you.
  • Simon Wednesday, September 16, 2020
    Hi Jose Angel,

    you can create Gluster Volumes, no problem at all.
    On each of them you can then create a "Storage Domain" where to guest your Virtual Machines.

  • Jared Tuesday, September 22, 2020
    John, most of the documentation I see points to OEL 7.7, while some of it says "or later". My question is is OEL7.8 supported, or better yet, is OEL8 supported? I haven't seen anything that specifically said no, but I haven't seen anything that didn't say 7.7 either.
  • Simon Wednesday, September 23, 2020
    Hi Jared,

    it's not more OEL, it's OL :)
    That said, OLVM 4.3 supports OL 7.7 and higher updates for OL7 (so OL8 is excluded).

  • Costin Friday, October 9, 2020
    any hope for 4.4 or at least 4.3.9, anytime soon? bugs prevent using 4.3.6 with hosted engine, which are already fixed long time ago in 4.3.9 (ovirt on ovirt node works, olvm on ol7 does not)
  • john priest Friday, October 23, 2020
    Please open up a Service Request for any issues that are encountered. The Oracle team is releasing errata updates as needed for specific issues and we are planning for an update OLVM 4.3 release to refresh a larger set of RPMs.
