Enable Yum Repositories

To use any of the Oracle KVM stacks, first enable the ol9_kvm_utils yum repository before installing the virtualization packages.

Ensure that the following are true before proceeding:

• The system meets the virtualization package requirements . See KVM Host: System Requirements and Virtualization Package Sources.
• UEK8U2 (UEK Release 8 Update 2) is installed and running on the system.
• You have administrator privileges.

This task is only required when using Oracle KVM stacks. The Default KVM stack is available in the standard yum repositories and can be installed without enabling any other repositories.

Tip:

If the Oracle KVM stack is already installed and you want to switch KVM stacks, see Switch KVM Stacks.

Important:

The Oracle KVM stack packages in ol9_kvm_utils provide QEMU 10.1 and libvirt 12.0 and have explicit dependencies on UEK8U2 kernel packages. If the system is running UEK7 and UEK8 repositories are not enabled/available, you remain on the QEMU 7.2 and libvirt 9.0.

Follow these steps to enable the ol9_kvm_utils repository.

1. Install or update the release package:

   sudo dnf install -y oraclelinux-release-el9

2. Enable the Oracle Linux 9 yum repository, by running the dnf config-manager command:

   sudo dnf config-manager --enable ol9_kvm_utils

After enabling the ol9_kvm_utils repository, you can install the Oracle KVM Stack. See Install Virtualization Packages.
