Install / Upgrade from previous versions



In order to install this Alplha Release you will need to enable pre-release repository.

In order to install it on a clean system, you need to install

# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43-pre.rpm

and then follow our Installation Guide.

Fedora Tech Preview

With oVirt 4.3 we are reintroducing Fedora 28 as platform for running oVirt in tech preview. More recent builds for Fedora are built for the master branch, so users that want to test them, can use the nightly snapshot. For some of the work to be done to completely restore support for Fedora, see also tracker bug 1460625.

oVirt Hosted Engine

If you're going to install oVirt as a Hosted Engine on a clean system please follow Hosted_Engine_Howto#Fresh_Install guide or the corresponding section in Self Hosted Engine Guide.

If you're upgrading an existing Hosted Engine setup, please follow Hosted_Engine_Howto#Upgrade_Hosted_Engine guide or the corresponding section within the Upgrade Guide.


Don't enable all of EPEL on oVirt machines.

The ovirt-release package enables the EPEL repositories and includes several specific packages that are required from there. It also enables and uses the CentOS SIG repos, for other packages.

If you want to use other packages from EPEL, you should make sure to use includepkgs and add only those you need avoiding to override packages from other repos.

What's New in 4.3.0?

Release Note

oVirt Engine

  • BZ 1599321 Config values inconsistency between RHV versions
    There are inconsistencies in the following internal configuration options:
    - HotPlugCpuSupported
    - HotUnplugCpuSupported
    - HotPlugMemorySupported
    - HotUnplugMemorySupported
    - IsMigrationSupported
    - IsMemorySnapshotSupported
    - IsSuspendSupported
    - ClusterRequiredRngSourcesDefault
    Systems that have upgraded from RHV 4.0 to RHV 4.1/4.2 and are experiencing problems with these features should upgrade to RHV 4.2.5 or later.

oVirt Release Package

  • BZ 1609884 ovirt-release-master for centos doesn't contain current ovirt-web-ui
    oVirt Release package for master is now enabling a new repository hosted on COPR service for delivering ovirt-web-ui packages.



  • BZ 1598391 [RFE] - Certify OSP 14 with OVN as an external network provider on RHV 4.3
  • BZ 1587892 After importing KVM VM the actual size is bigger than the virtual size

    Added KVM Sparseness support to KVM to oVirt Virtual Machine Importing so that when Thin Provisioning is enabled, the Disk Size of the original KVM Image will be preserved after importing to oVirt.


    Unless the user specifically specifies pre-allocation, the Disk Size of the Virtual Machine should be no larger than required during initial allocation of Disk Space when the VM is running. Previously when choosing Thin Provisioning for KVM to oVirt Importing, the Disk Size of the VM within the Storage Domain of oVirt was inflated to the Volume Size or Larger when the original KVM VM was much smaller.


    Now when Importing Virtual Machines from KVM to oVirt with Thin Provisioning selected, the original Disk Size of the VM is preserved.
  • BZ 1510856 [RFE] Time sync in VM after resuming from PAUSE state

    Added optional Guest Time Synchronization to the snapshot functionality via the time_sync_snapshot_enable option and other un-pausing scenarios via the time_sync_cont_enable option for synchronizing and correcting the time on the VM after long pauses. The defaults for the option are turned off for backward compatibility.


    This becomes especially critical when there are heavy loads on the VM to ensure time stamps for example are accurate.


    When the options are enabled, the VDSM shall attempt to synchronize the time either during pauses that occur via during snapshots and/or during other un-pausing functionality.

oVirt Engine

  • BZ 1619210 [RFE] Provide Live Migration for VMs based on "High Performance VM" Profile - automatic migrations
  • BZ 1111783 [RFE][TestOnly] Provide SCSI reservation support for virtio-scsi via rhev-guest-tools for win-8 and win-2012 guests using Direct-Lun as disks
    With this release Windows clustering is supported for iSCSI based direct attached LUNs.
  • BZ 1598391 [RFE] - Certify OSP 14 with OVN as an external network provider on RHV 4.3
  • BZ 1327846 [RFE] Q35: Support booting virtual machines via UEFI
  • BZ 1590202 [RFE] Disable Event notification popup in admin portal
    This adds a feature to control toast notifications. Once 3 or more notifications are showing, "Dismiss" and "Do not disturb" buttons will appear that allow the user to silence notifications.
  • BZ 1571399 [RFE] Improve UI plugin API for adding action buttons
    Feature: When adding custom action buttons (located above main or details tab grid) via UI plugin API, it's now possible to specify the relative position of the button and whether it should be placed in the "more" menu.

    Reason: Give UI plugins more control over plugin-contributed action button placement.

    Result: When calling addMenuPlaceActionButton/addDetailPlaceActionButton API functions, you can now pass "index" and "moreMenu" options to customize the relative position of the button and whether it should be placed in the "more" menu. By default, the button will be placed at the end (after all existing buttons) and outside the "more" menu.
  • BZ 1559694 RFE: warn user if VM does not fit in a single numa node of the host
    If a VM does not use virtual NUMA nodes, it is better if its whole memory can fit into a single NUMA node on the host. Otherwise, there may be some performance overhead.

    There are two additions in this RFE:
    1. New warning message is shown in the audit log, if a VM is run on a host where its memory cannot fit to a single host NUMA node.

    2. A new policy unit is added to the scheduler, 'Fit VM to single host NUMA node'. When starting a VM, this policy prefers hosts where the VM can fit to a single NUMA node. This unit is not active by default, because it can cause undesired edge cases.

    For example, the policy unit would cause the following behavior when starting multiple VMs.
    It the following setup:
    - 9 hosts with 16 GB per NUMA node
    - 1 host with 4 GB per NUMA node

    When multiple VMs with 6 GB of memory are scheduled, the scheduling unit would prevent them from starting on the host with 4 GB per NUMA node. No matter how overloaded the other hosts are. It would use the last host only when all the others does not have enough free memory to run the VM.
  • BZ 1009608 [RFE] Limit east-west traffic of VMs with network filter

    Limit east-west traffic of VMs.


    To enable traffic only between VM and gateway.


    The new filter 'clean-traffic-gateway' has been added to libvirt. With parameter called 'GATEWAY_MAC' user can specify MAC address of gateway that is allowed to communicate with the VM and vice versa. Please note that user can specify multiple 'GATEWAY_MAC'.

    There are two possible configurations of VM:

    1) VM with static IP

    This is recommended setup. It is also recommended setting of parameter 'CTRL_IP_LEARNING' to 'none', any other value will result in leak of initial traffic. This is caused by libvirt learning mechanism (see https://libvirt.org/formatnwfilter.html#nwfelemsRulesAdvIPAddrDetection and https://bugzilla.redhat.com/show_bug.cgi?id=1647944 for more details).

    2) VM with DHCP

    DHCP is working partially. It is not usable in production currently (https://bugzilla.redhat.com/show_bug.cgi?id=1651499).

    The filter has general issue with ARP leak (https://bugzilla.redhat.com/show_bug.cgi?id=1651467). Peer VMs are able to see that the VM using this feature exists (in their arp table), but are not able to contact the VM, as the traffic from peers is still blocked by the filter.
  • BZ 1454673 [RFE] Changes that require Virtual Machine restart: name
    When a request to rename a virtual machine arrives, change the name of the virtual machine immediately also when the QEMU process is running and is set with the previous name.

    Users typically want to see and use the new name a virtual machine is set with even when it is running.

    When renaming a running virtual machine, the new name is applied immediately. In this case, the user is provided with a warning that indicates that the running instance of the virtual machine uses the previous name.
  • BZ 1553902 [RFE] Update UI plugin API to reflect current UI design
    Starting with oVirt 4.3, the UI plugin API is updated to reflect recent web administration UI design changes.

    In general, there are two types of changes:

    (1) new API functions:
    - addPrimaryMenuContainer & addSecondaryMenuPlace that allow plugins to add custom secondary menu items to the vertical navigation menu

    (2) renaming of existing API functions:
    - addMainTab => addPrimaryMenuPlace
    - addSubTab => addDetailPlace
    - setTabContentUrl => setPlaceContentUrl
    - setTabAccessible => setPlaceAccessible
    - addMainTabActionButton => addMenuPlaceActionButton
    - addSubTabActionButton => addDetailPlaceActionButton

    The reason for renaming API functions (2) is to stay consistent with current web administration UI design - most notably, the absence of "main" and "sub" tabs.

    All existing API functions are still supported. For API functions that were renamed (2), it's still possible to use the original ones, but doing so will yield a warning in the browser console, for example:

    "addMainTab is deprecated, please use addPrimaryMenuPlace instead."

    Additionally, for functions [addPrimaryMenuPlace, addPrimaryMenuContainer, addSecondaryMenuPlace, addDetailPlace] and their deprecated equivalents, the options object no longer supports alignRight (boolean) parameter. This is because PatternFly tabs widget [1] expects all tabs to be aligned next to each other, flowing from left to right.

    [1] http://www.patternfly.org/pattern-library/widgets/#tabs

    For details, please consult the oVirt UI plugins feature page.
  • BZ 1518697 engine-setup upgrade of postgres to pg95 env variables not stored to answer file
    engine-setup now uses otopi's new functionality to generate its answer files, which should automatically cover all future added questions without requiring specific code for handling them. The option '–config-append' is compatible with both kinds of files, although the actual behavior will be somewhat different.
  • BZ 968435 [RFE] Present in the UI the correlation between virtual disks in a VM and what the VM sees
  • BZ 1530031 [RFE] engine-backup should have defaults for most options
    engine-backup now has defaults for most options, so they do not need to be supplied usually.

    TODO update with the new defaults once we decide what these are.
  • BZ 1131178 [RFE] Include storage domain UUID in Storage Domain 'General' tab
  • BZ 1570077 [RFE] Add UI plugin API function to allow tab/place resource cleanup
    Feature: After adding custom primary/secondary menu item or details tab via UI plugin API, it's now possible to attach "unload" handler to perform any UI-plugin-specific cleanup once the user navigates away from the given primary/secondary menu item or details tab.

    Reason: Allow UI plugins to attach "unload" handler for each plugin-contributed WebAdmin UI application place, i.e. custom primary/secondary menu item or details tab.

    Result: After adding the custom application place via addPrimaryMenuPlace/addSecondaryMenuPlace/addDetailPlace API functions, you can attach "unload" handler for that place by calling api.setPlaceUnloadHandler(place, handler) function.
  • BZ 1651255 Cannot set number of IO threads via the UI
    The number of IO threads can be set in the web UI in the new/edit VM dialog.

    Some users may need to set the number of IO threads and using web UI can be easier than REST API.
  • BZ 1560132 [RFE] Add finer grained monitoring thresholds for memory consumption on Hypervisors to RHV
    In the Administration Portal, it is possible to set a threshold for cluster level monitoring as a percentage or an absolute value, for example, 95% or 2048 MB. When usage exceeds 95% or free memory falls below 2048 MB, a "high memory usage" or "low memory available" event is logged. This reduces log clutter for clusters with large (1.5 TB) amounts of memory.

oVirt Host Dependencies

  • BZ 1598318 Require SCAP in ovirt-host
    The openscap, openscap-utils and scap-security-guide packages have been added to oVirt Node in order to help hardening the oVirt Node deployments.

oVirt Hosted Engine Setup

  • BZ 1209881 [RFE] remove iptables from hosted-engine.spec file to be able to deploy hosted-engine without firewall services installed
    Feature: Remove iptables dependency

    Reason: to be able to deploy hosted-engine without firewall services installed

oVirt Release Package

  • BZ 1598318 Require SCAP in ovirt-host
    The openscap, openscap-utils and scap-security-guide packages have been added to oVirt Node in order to help hardening the oVirt Node deployments.

oVirt Windows Guest Tools

  • BZ 1620569 Include linux qemu-guest-agent on RHV Guest Tools iso for v2v offline conversion
    Qemu Guest Agent packages for several Linux distributions have been added to ease offline installation of the guest agent
  • BZ 1578782 [RFE] Add smbus driver in windows guest tools
    Feature: virtio-smbus driver installer has been added to RHV Windows Guest Tools

    Reason: When a guest running Windows 2008 with Q35 bios an unknown device is listed in Device Manager being the smbus device unrecognized

    Result: smbus device is now recognized.

oVirt Engine Appliance

  • BZ 1578835 [RFE] Add ovirt-engine-extension-aaa-ldap-setup and ovirt-engine-extension-aaa-ldap to RHV-M Image
    Add engine-extensoin-aaa-ldap to the rhvm image

    Enable LDAP provider

    engine-extensoin-aaa-ldap is shipped in the rhvm image

oVirt Node NG Image

  • BZ 1527120 [RFE][CodeChange] split the jenkins job and the gerrit repo if needed for nodectl tool and node-ng iso

Removed functionality


  • BZ 1601873 Remove dependency on gluster-gnfs to support Gluster 4.1
    gluster-gnfs is no longer available with Gluster 4.1. Users that require nfs access for gluster volumes are advised to use nfs-ganesha. Please refer https://gluster.readthedocs.io/en/latest/Administrator%20Guide/NFS-Ganesha%20GlusterFS%20Integration/

Deprecated Functionality

oVirt Engine

  • BZ 1627636 Drop ovirt-engine-cli dependency
    ovirt-engine-cli uses v3 API which are deprecated and unsupported.
    We'll keep shipping the package but we are not depending on it anymore.
  • BZ 1533086 deprecate and remove disks scan alignment feature
    The "Scan Alignment" feature in the webadmin was only relevant to outdated guest OSes, which are no longer supported anyway.

    The feature is now removed from the webadmin, along with histoprical records of disks being aligned or malaligned.

Known Issue


  • BZ 1381135 [FC28] otopi fails to detect firewalld if python2-firewall is not available
    In fedora 24, python3 is used by default in most of the system commands.
    In particular firewall-cmd is now runing on python3 so python2-firewall is not installed by default.
    OTOPI runs on python2 so it can't use the python3 module.
    In order to allow OTOPI to detect and use firewalld the python2-firewall package has to be installed on the system.
