oVirt 4.3.0 Release Notes

The oVirt Project is pleased to announce the availability of the 4.3.0 release as of February 04, 2019.

oVirt is a free open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.

This release is available now for Red Hat Enterprise Linux 7.6, CentOS Linux 7.6 (or similar).

If you’d like to try oVirt as quickly as possible, follow the instructions on the Download page.

For complete installation, administration, and usage instructions, see the oVirt Documentation.

For a general overview of oVirt, read the About oVirt page.

To learn about features introduced before 4.3.0, see the release notes for previous versions.


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.

Known Issues

What’s New in 4.3.0?

Release Note


  • BZ 1655115 Drop 3.6 and 4.0 datacenter/cluster level
    The current release removes the VDSM daemon’s support for cluster levels 3.6/4.0 and Red Hat Virtualization Manager 3.6/4.0. This means that VDSM from RHV 4.3 cannot be used with the Manager from RHV 3.6/4.0. To use the new version of VDSM, upgrade the Manager to version 4.1 or higher.
  • BZ 1514004 [downstream clone - 4.3.0] [RFE] Drop TLSv1 and TLSv1.1 encryption protocols support
    The TLSv1 and TLSv1.1 protocols are no longer secure. They have been forcefully disabled in the VDSM configuration and cannot be enabled.

    Only TLSv1.2 and higher versions of the protocol are enabled. The exact version enabled depends on the underlying OpenSSL version.

oVirt Engine

  • BZ 1627756 On engine side replace fluentd dependencies with rsyslog
    The current release replaces Fluentd with Rsyslog for collecting oVirt logs and collectd metrics. Systems running Red Hat Virtualization Manager and upgraded from 4.2 will still have Fluentd installed but it will be disabled and stopped.
    After upgrading to 4.3, you can remove the Fluentd packages.
  • BZ 1550634 Drop 3.6 and 4.0 datacenter/cluster level
    This release removes the Red Hat Virtualization Manager support for clusters levels 3.6 and 4.0. Customers must upgrade their data centers to Red Hat Virtualization Manager 4.1 or later before upgrading to Red Hat Virtualization Manager 4.3.
  • 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.
  • BZ 1651220 Require Ansible 2.7+
    This release adds a requirement for Ansible version 2.7, the lowest version required to run oVirt Ansible roles.

oVirt Host Dependencies

  • BZ 1627753 On hosts replace fluentd dependencies with rsyslog
    The current release replaces Fluentd with Rsyslog for collecting oVirt logs and collectd metrics.
    Hosts upgraded from 4.2 will still have Fluentd installed, but the service is disabled and stopped.
    After upgrading to 4.3, you can remove the fluentd packages.

oVirt Release Package

  • BZ 1609884 ovirt-release-master for centos doesn’t contain current ovirt-web-ui
    In this release, the oVirt release package for master, ovirt-release-master, enables a new repository hosted on the Cool Other Package Repositories (COPR) service for delivering ovirt-web-ui packages.



  • BZ 1644693 High Host CPU load for Windows 10 Guests (Update 1803) when idle
    Feature: Added enlightenment support in order to reduce CPU load by enabling the hyper-visor synic and stimer states.

    Reason: To improve performance when running Windows as a guest OS.

    Result: Anticipated results are that CPU load will be reduced to 0-5% on Linux Virtual Machines.
  • BZ 1641125 [RFE] add a configuration policy for vGPU placement
    It is now possible to set in host configuration preferred vGPU placement on physical cards. Separated placement prefers putting each vGPU on a separate physical card, consolidated placement prefers putting more vGPUs on available physical cards.
  • BZ 1598391 [RFE] - Certify OSP 14 with OVN as an external network provider on RHV 4.3
    Neutron from OSP 14 configured to use OVN can be used as an external network provider on RHV 4.3 with the limitation described in bug 1655906 .
  • BZ 1625612 [RHV] failed to convert VMware ESX VM with snapshot
    Feature: Removes the code within the VDSM blocking the importing of VMWare VMs with snap shots in order to take advantage of virt-v2v support for importing these types of VMs that was added to the virt-v2v-1.36.10-6.el7.x86_64.rpm package.

    Reason: We would like to expose this feature for use by oVirt users.

    Result: oVirt now supports the importing of VMware VMs that include snap shots.
  • 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.
  • BZ 1451297 [RFE] Drop TLSv1 and TLSv1.1 encryption protocols support
    TLSv1 and TLSv1.1 protocols are no longer secure, so they are forcefully disabled in VDSM configuration and cannot no longer be enabled within configuration.

    Only TLSv1.2 and higher version of protocols are enabled, exact versions depends on underlying openssl version.

oVirt Engine

  • BZ 1644693 High Host CPU load for Windows 10 Guests (Update 1803) when idle
    Feature: Added enlightenment support in order to reduce CPU load by enabling the hyper-visor synic and stimer states.

    Reason: To improve performance when running Windows as a guest OS.

    Result: Anticipated results are that CPU load will be reduced to 0-5% on Linux Virtual Machines.
  • BZ 1661921 ovirt-provider-ovn TLS hardening (Default use of TLSv1.2 and HIGH ciphers only)
    - internal OVN db connections are encrypted by TLS 1.2 with ‘HIGH’ chiphers in
    new RHV 4.3 installations by default
    - Ciphers used on ovirt-provider’s OpenStack REST API are configurable

    - bug 1459441 enables RHV to configure the encryption of OVN internal connections
    - default OpenSSL config in RHEL 7 allows usage of insecure ciphers

    - in RHV 4.3 default config internal OVN connections and
    ovirt-provider’s OpenStack REST API uses TLS 1.2 and HIGH ciphers.
  • BZ 1571371 [RFE] Allow pinning a VM (specifically high-performance) with vNUMA to more than one host
    Feature: A VM with NUMA pinning enabled can now be configured to run on a set of assigned/pinned hosts (one or more).

    Reason: Up till now there was a limitation that only one host (and not more than one) can be assigned to a VM, in case of NUMA nodes pinning is enabled.

    Result: A VM with NUMA pinning enabled can now be configured to run on a set of assigned/pinned hosts, one or more (by selecting the “Start running on: Specific Host” in “Host” side-tab).
    Each one of this hosts should have the same pinning settings so that VM can run on each and this is verified by the engine.
    This change is crucial for supporting High Availability for those VMs.
  • BZ 1641125 [RFE] add a configuration policy for vGPU placement
    It is now possible to set in host configuration preferred vGPU placement on physical cards. Separated placement prefers putting each vGPU on a separate physical card, consolidated placement prefers putting more vGPUs on available physical cards.
  • BZ 1539829 [RFE] Provide support for adding security groups and rules using ovirt-provider-ovn
    This feature provides security group support, as described by the OpenStack Networking API.
  • BZ 1619210 [RFE] Provide Live Migration for VMs based on “High Performance VM” Profile - automatic migrations
    This feature provides the ability to enable live migration for HP VMs (and in general to all VM types with pinning settings).

    n oVirt 4.2 we added a new “High Performance” VM profile type. This required configuration settings includes pinning the VM to a host based on the host specific configuration. Due to that pinning settings, the migration option for the HP VM type was automatically forced to be disabled.

    in oVirt 4.3 we will provide the ability for live migration of HP VMs (and all other VMs with pinned configuration like NUMA pinning, CPU pinning and CPU pass-through enabled).

    For more details, please refer to the feature page
  • BZ 1648190 [RHEL76] libvirt is unable to start after upgrade due to malformed UTCTIME values in cacert.pem, because properly renewed CA certificate was not passed to hosts by executing “Enroll certificate” or “Reinstall”
    Internal CAs generated in the past (<= 3.5) can contain UTCTIME values without timezone indication and this is not acceptable anymore with up to date openssl and gnutls libraries.
    engine-setup was already checking it proposing a remediation but the user can postpone it, making it more evident since now postponing can cause serious issues.
  • 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
    Neutron from OSP 14 configured to use OVN can be used as an external network provider on RHV 4.3 with the limitation described in bug 1655906 .
  • 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 1527860 [RFE] Q35: change piix3-usb controller (USB1) to qemu-xhci controller (USB3)
    Feature: Adding USB qemu-xhci controller support to SPICE consoles.

    Reason: For Q35 chipset support

    Result: We expect when a Bios type using the Q35 chipset is chosen and usb is enabled that the USB controller shall be qemu-xhci.
  • BZ 1611889 Switch from ENI to OMP dumps network config to different file and breaks EL6 guests
    Feature: Allow the user to select the cloud init protocol with which to create the network configuration for the VM

    Reason: in odler versions of cloud-init, backward compatibility needs to be maintained with the ENI protocol whereas on newer cloud-init versions the Openstack-Metadata protocol is supported.

    Result: engine now supports selection of the cloud-init protocol to use as part of the cloud-init parameter entry form, while creating a new VM or editing an existing one or starting a VM with Run Once.
  • BZ 1388098 [RFE] Prevent RHV-M from restarting hosts during large outage
  • BZ 1630243 [RFE] Show live migration progress bar also in virtual machine tab in host page
    During VM live migration, the migration progress bar is shown also in the host page on the virtual machine tab.
  • 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 and for more details).

    2) VM with DHCP

    DHCP is working partially. It is not usable in production currently (

    The filter has general issue with ARP leak ( 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.


    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 1286219 [RFE] Disk alias of cloned VM should be Alias_</b>
    Change the disk alias of cloned VM.

    Disk alias of cloned VM should be Alias_.

    After cloning a VM, its disks are named as
  • BZ 1540921 [RFE] Deprecate and remove support for Conroe and Penryn CPUs

    Deprecated Conroe and Penryn CPU Types from Compatibility Version 4.3


    We no longer want to support them.


    Conroe and Penryn CPU Types no longer appear for Compatibility Version 4.3 and a warning is displayed for older versions.
  • 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 1602968 [RFE] Add “power off VM” to the right-click popup menu in the GUI
    Feature: “Power Off VM” was missing from the context menu in the RHV-M administrator portal

    Reason: This was present in previous versions, but removed as part of the new user interface.

    Result: “Power Off VM” is present when a running VM is right-clicked
  • 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 1580346 Cluster properties ‘Enable to set host/VM…’ should be set by default (and hidden?)
  • BZ 1454389 [RFE] add search query for cluster compatibility level override
    Added a search query to list all VMs with specific cluster compatibility override.

    The new queries are:
    - Vms: custom_compatibility_version = X.Y
    - Vms: custom_compatibility_version != X.Y

    The first lists all VMs with cluster compatibility override to version X.Y and the second lists VMs with different cluster compatibility override version or without any cluster compatibility override set.
  • BZ 1408584 [RFE] Host cpu type is not found anywhere in REST API
    Feature: Added the CPU Type to the REST API’s Host details.

    Reason: The REST API should be consistent with the UI which does display the CPU Type.

    Result: The REST API now returns the CPU Type with the rest of the Host data.
  • BZ 1561413 [RFE] Remove option should be grayed out for delete protected VMs
    Feature: Since delete-protected VMs cannot be modified, including removal, destructive operations are now disabled.

    Reason: Previously, this button was enabled, but did not perform any operations, leading to an inconsistent user experience.

    Result: “Remove” is now disabled if a VM is delete protected
  • 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.

    Feature: Remove iptables dependency

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

oVirt Engine Data Warehouse

  • BZ 1614818 [RFE] Upgrade to Software Collections PostgreSQL 10
    Documentation changes are being tracked in BZ1641460

oVirt Engine Metrics

  • BZ 1629437 Update ovirt-engine-metrics playbooks to use the linux-system-roles logging roles
    As part of replacing Fluentd wih Rsyslog we are basing the Rsyslog deployment on the linux-system-roles logging role, which is a rhel ansible role for deploying Rsyslog configuration files and service handling for multiple projects.

    This role will be maintained by RHEL and makes the Rsyslog deployment easier and more maintainable.

    Rsyslog service and configurations are deployed on the oVirt engine and hosts during the ovirt metrics deployment.

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.

    Qemu Guest Agent packages for several Linux distributions have been added to ease offline installation of the guest agent
  • BZ 1578775 [RFE] Add qemufwcfg driver in windows guest tools
    The virtio qemufwcfg driver has been added to oVirt Windows Guest Tools for Windows 10 and Windows Server 2016.
    The driver doesn’t provide any functionality but prevents Windows Device Manager to display the device as unrecognized.
  • 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.

  • BZ 1601873 Remove dependency on gluster-gnfs to support Gluster 4.1
    In this release, gluster-gnfs is no longer available with Gluster 4.1. Users who require nfs access for gluster volumes are advised to use nfs-ganesha. Please refer to

Deprecated Functionality

oVirt Engine

  • BZ 1399750 [RFE] Make API v3 officially unsupported
    Version 3 of the REST API has been deprecated as of RHV version 4.0. It will not be supported from RHV version 4.3, along with the ovirt-shell and version 3 of the Python SDK Guide, Ruby SDK Guide, and Java SDK Guide.
  • BZ 1627636 Drop ovirt-engine-cli dependency
    The ovirt-engine-cli package uses the version 3 REST API which is deprecated and unsupported.
    With this update, ovirt-engine-cli is no longer a dependency and is not installed by default.
  • BZ 1533086 deprecate and remove disks scan alignment feature
    The “Scan Alignment” feature in the previous versions of the Administration Portal is only relevant to guest OSes that are outdated and unsupported.

    The current release removes this “Scan Alignment” feature, along with historical records of disks being aligned or misaligned.

Rebase: Bug Fixeses Only

oVirt Engine

  • BZ 1625591 After importing KVM VM, removing the VM and re-importing, the re-importing fails
    Previously, after importing and removing a Kernel-based Virtual Machine (KVM), trying to re-import the same virtual machine fails with an error that the Job ID already exists.

    This update ensures that import jobs are deleted in the VDSM after importing.
