Virtualization Package Sources

Oracle distributes two sets of KVM user space packages, called stacks. These KVM stacks define which versions of virtualization hypervisor packages install and run on an Oracle Linux system.

Each stack has its own separate source, so you might need to configure the package sources on the system depending on which KVM stack you want to install.

Note:

If the system is running UEK, you can choose to switch between stacks. For more details, see Switch KVM Stacks.

The following table lists the KVM stacks available for deployment to an Oracle Linux 9 system, their benefits and support limitations, and their corresponding package sources.
