Installing on RHEL 8.6 or derivatives

In order to install oVirt 4.5 on RHEL 8.6 or derivatives you’ll need to provide CentOS Stream required configuration. The following bash code is needed before starting to install oVirt 4.5 on top of RHEL 8.6

Specific to RHEL only:

subscription-manager repos --enable rhel-8-for-x86_64-baseos-rpms
subscription-manager repos --enable rhel-8-for-x86_64-appstream-rpms
subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms

rpm -i --justdb --nodeps --force "https://vault.centos.org/centos/8-stream/BaseOS/$(rpm --eval '%_arch')/os/Packages/centos-stream-release-8.6-1.el8.noarch.rpm"

Specific to Rocky Linux only:

# On Rocky there's an issue with centos-release-nfv package from extras
dnf install -y dnf-plugins-core
dnf config-manager --set-disabled extras

Due to Bug 2091581, while installing the virtualization host you will be missing nmstate-plugin-ovsdb or python3-libnmstate unless you install them from CentOS build nmstate-2.0.0-2.el9. While installing it you need to ensure openvswitch2.15 will be installed instead of any later version.

Here’s how to do that:

dnf install -y centos-release-ovirt45
dnf install -y ovirt-openvswitch
dnf install -y \
