Install / Upgrade from previous versions

Fedora / CentOS / RHEL

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

# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm

and then follow our Installation Guide.

If you're upgrading from a previous release on Enterprise Linux 7 you just need to execute:

  # yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm
  # yum update "ovirt-*-setup*"
  # engine-setup

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.

EPEL

TL;DR 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 4.1.5?

Enhancements

oVirt Release Package

  • BZ 1364083 [RFE] Provide ppc64le arch packages
    With this update, oVirt Host related packages are now also available for ppc64le architecture.

oVirt Engine

  • BZ 1022961 Gluster: running a VM from a gluster domain should use gluster URI instead of a fuse mount
    This release adds libgfapi support to the Manager and VDSM. libgfapi provides virtual machines with faster access to their images, stored on a Gluster volume, compared to a fuse interface. With the 'LibgfApi' data center feature enabled, or 'lubgfapi_supported' cluster-level feature enabled, virtual machines will access their images, stored on Gluster volumes, directly via libgfapi.

VDSM

  • BZ 1022961 Gluster: running a VM from a gluster domain should use gluster URI instead of a fuse mount
    This release adds libgfapi support to the Manager and VDSM. libgfapi provides virtual machines with faster access to their images, stored on a Gluster volume, compared to a fuse interface. With the 'LibgfApi' data center feature enabled, or 'lubgfapi_supported' cluster-level feature enabled, virtual machines will access their images, stored on Gluster volumes, directly via libgfapi.

oVirt Engine Metrics

  • BZ 1462500 Add a check that ovirt_env_name is a valid OpenShift namespace identifier
    This release adds checks to the ovirt_env_name, to make sure it is a valid OpenShift namespace identifier. If it is not, the metrics script will now fail. The name must be valid in order for the records to be kept by the Elasticsearch running in OpenShift.

oVirt Hosted Engine Setup

  • BZ 1457357 Allow editing all the shared storage configuration values
    You can now change more self-hosted engine configuration in the hosted-engine.conf file.
    For example, to set the value:
    hosted-engine –set-shared-config gateway 10.35.1.254

    To get the value:
    hosted-engine –get-shared-config gateway

    The commands can be used with the additional parameter "type", if there is concern for duplicate keys in different files:
    hosted-engine –set-shared-config gateway 10.35.1.254 –type=he_conf
    hosted-engine –get-shared-config gateway –type=he_conf

oVirt Hosted Engine HA

  • BZ 1457357 Allow editing all the shared storage configuration values
    You can now change more self-hosted engine configuration in the hosted-engine.conf file.
    For example, to set the value:
    hosted-engine –set-shared-config gateway 10.35.1.254

    To get the value:
    hosted-engine –get-shared-config gateway

    The commands can be used with the additional parameter "type", if there is concern for duplicate keys in different files:
    hosted-engine –set-shared-config gateway 10.35.1.254 –type=he_conf
    hosted-engine –get-shared-config gateway –type=he_conf

Deprecated Functionality

oVirt Engine

  • BZ 1473179 ovirt-engine-setup-plugin-dockerc is now deprecated
    The ovirt-engine-setup-plugin-dockerc package is now deprecated, and will be removed in version 4.2.

Bug Fixes

oVirt Release Package

  • BZ 1476650 RHV-H Upgrade Breaks System Clock Sync

oVirt Engine

  • BZ 1414499 [RFE] ability to download images that are attached to vms
  • BZ 1476979 Cannot set ImageProxyAddress with engine-config
  • BZ 1464819 [API] Setting Custom Compatibility Version for a VM via REST api to a none/empty value is not working

VDSM

  • BZ 1461029 Live merge fails when file based domain includes "images" in its path

imgbased

  • BZ 1476071 ovirt-imageio-daemon fails to run after upgrading from 4.0 NGN (as directory "/var/log/ovirt-imageio-daemon/" is owned by user root)
  • BZ 1478339 capabilities of /usr/bin/ping got corrupted after upgrade from 4.1.2 async to 4.1.3

oVirt Hosted Engine HA

Other

oVirt Engine

  • BZ 1437152 v2v import from VmWare via REST API doesn't override the original mac address
  • BZ 1454811 [downstream clone - 4.1.5] No error pops when logging with a locked ovirt user account
  • BZ 1475272 MAC addresses are not freed when a storage domain is destroyed from a data-center
  • BZ 1336708 disk enumeration order in API don't match disk order in the qemu command line
  • BZ 1481098 [downstream clone - 4.1.5] engine does not start due to trying to call non-existent callback.
  • BZ 1465859 OVESETUP_ENGINE_CONFIG/fqdn value not getting logged in answerfile when installing remote dwh
  • BZ 1476744 No validation on the storage_domain parameter when creating VM disks attachments
    Cause: There was no validation on the storage_domain parameter on SDK / REST API. Therefore, it was "possible" to create a vm's disk_attachment without a storage_domain.

    Consequence: Disk attachment has been created, and the storage_domain's parameter was set as the other VM's disk storage domain.

    Fix: Add validation for the storage_domain parameter which supplied by the user (as a part of SDK / REST API command parameters).

    Result: Error message which indicates that storage_domain wasn't supplied + operation stops.
  • BZ 1477375 v2v: In audit log IMPORTEXPORT_STARTING_IMPORT_VM is accompanied by ID of the source VM instead of the destination one
