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 4.1.8?

Release Note

VDSM

  • BZ 1513886 [downstream clone - 4.1.8] [RFE] Enable TLSv12 support by default
    This update ensures that TLSv12 support is enabled by default and no manual configuration is required.

Enhancements

oVirt Engine Dashboard

  • BZ 1504691 [downstream clone - 4.1.8] [RFE] Create a Refresh button on Dashboard in Manager UI
    In this release, a refresh button has been added to the Dashboard tab in the Administration
    Portal to enable users to view up-to-date system summary information.

oVirt Release Package

  • BZ 1516194 [downstream clone - 4.1.8] [RFE] Provide IdM client software in RHVH
    The ipa-client package is now installed on hosts, and is included in the Red Hat Virtualization Host image. This enables Cockpit certificate signing and SSO with Red Hat IdM, and adding the host to an IdM realm.

oVirt Engine

  • BZ 1501793 [downstream clone - 4.1.8] [RFE] Indicate host needs to be reinstalled to push new configurations.
    There are several cluster and host settings which require reinstallation of the host if changed. The requirement to reinstall was always mentioned in documentation and a WARNING event was raised. With this release, the Administration Portal now also shows an exclamation mark icon for each host that needs to be reinstalled. When an exclamation mark icon is shown, you can find the details about it in the Action Items section of the host’s details view.
  • BZ 1505576 Cannot specify proper CPU topology for 4-socket broadwell (24 cores per socket)
    Feature:
    Support more than 16 cores per socket

    Reason:
    Modern CPUs do support more, qemu does not have problem with that, this restriction just artificially constrained the user to create a virtual HW which matches the physical

    Result:
    254 cores per socket is now supported.

oVirt Engine Metrics

  • BZ 1506458 [RFE] Add support for fluent-plugin-elasticsearch and use it as default
    Feature:
    Update fluentd client role to send data from the fluentd on the hosts directly to elasticsearch, by default instead of the central fluentd(mux).



    Reason:
    Sending the metrics data and logs data to the central fluentd(mux) had performance issues.

    Result:
    This required adding support to configure the fluent-plugin-elasticsearch plugin. It will be the default output plugin.
  • BZ 1475900 [RFE] Collect the logs from vdsm.log to the metrics store
    Feature:
    Collect the logs from vdsm.log to the metrics store

    Reason:
    In order to allow the users a common logging where they can explore both vdsm and engine logs.

    Result:
    vdsm.log is now collected to the metric store from each host.
  • BZ 1506174 Add README to ovirt-engine-metrics ansible roles

oVirt Engine Extension AAA-LDAP

  • BZ 1489402 Provide an example for kerberos authentication between aaa-ldap and LDAP server
    Feature:

    Following examples has been added:

    * Using GSSAPI to authenticate against IPA
    * Using GSSAPI with ticket cache to authenticate against IPA

    More details about those examples can be found at README.md [1] which is also included inside the package

    [1] https://github.com/oVirt/ovirt-engine-extension-aaa-ldap/blob/master/examples/README.md

    Reason:

    Result:

oVirt Host Dependencies

  • BZ 1516194 [downstream clone - 4.1.8] [RFE] Provide IdM client software in RHVH
    The ipa-client package is now installed on hosts, and is included in the Red Hat Virtualization Host image. This enables Cockpit certificate signing and SSO with Red Hat IdM, and adding the host to an IdM realm.

Rebase: Enhancementss Only

oVirt Log collector

  • BZ 1512308 [downstream clone - 4.1.8] [RFE] option to collect logs from one host per cluster
    This is a rebase of the package to version 4.1.7. A notable enhancement is an option has been added to collect logs from one host per cluster.
