Install / Upgrade from previous versions

Fedora / CentOS / RHEL

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

# yum localinstall http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm

If you are upgrading from a previous version, you may have the ovirt-release34 package already installed on your system. You can then install ovirt-release35.rpm as in a clean install side-by-side.

Once ovirt-release35 package is installed, you will have the ovirt-3.5-stable repository and any other repository needed for satisfying dependencies enabled by default.

If you are upgrading from oVirt < 3.4.1, you must first upgrade to oVirt 3.4.1 or later. Please see oVirt 3.4.1 release notes for upgrade instructions.

For upgrading now you just need to execute:

  # yum update "ovirt-engine-setup*"
  # engine-setup

oVirt Live

A new oVirt Live ISO is available:
