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-release40.rpm

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-release40.rpm
  # yum update "ovirt-engine-setup*"
  # engine-setup

Upgrade on Fedora 22 and Enterprise Linux 6 is not supported and you should follow our Migration Guide in order to migrate to Enterprise Linux 7 or Fedora 23.

Known issues

  • BZ 1297835 Host install fails on Fedora 23 due to lack of dep on python2-dnf
    On Fedora >= 23 dnf package manager with python 3 is used by default while ovirt-host-deploy is executed by ovirt-engine using python2. This cause Host install to fail on Fedora >= 23 due to lack of python2-dnf in the default environment. As workaround please install manually python2-dnf on the host before trying to add it to the engine.

What’s New in 4.0.1?

Enhancement

oVirt Engine

Team: Infra
  • BZ 1268133 [RFE] RHEV Manager support for SNMPv3 traps

    Result:
    Sampling in scale environment is taking less then 15 seconds.
