+## Install Oracle Linux Virtualization Engine
+
+The `default_vars.yml` file contains several variables that enable you to automate steps in the setup and configuration of Oracle Linux Virtualization Manager. Here is a list of those variables and what they do:
+
+- **install_engine:** Runs the *provision_olvm_engine.yml* playbook, which installs the packages for the engine and KVM hosts and then executes `engine-setup`.
+- **copy_engine_publickey:** Runs the *provision_olvm_engine_publickey.yml* playbook, which copies the engine public key to each KVM host.
+- **config_olvm:** Runs a series of *ovirt* playbooks that configure Oracle Linux Virtualization Manager based on the steps provided in the associated [lab](https://luna.oracle.com/lab/c912c867-a5cd-420e-9ee5-ee9017b2b957).
