This document provides guidance on how to apply the kvm-playbook.yml playbook against the hypervisors using Ansible and how to understand the associated hosts.ini inventory file.

The hosts.ini file is an Ansible inventory file that defines one group:

• [hypervisors]: This group should contain a list of hypervisor hosts. You'll need to list the IP addresses or hostnames of the hypervisors below this line.

Example:

[hypervisors]
172.18.1.10
172.18.1.20

To run the playbook against the hypervisors, use the following command:

ansible-playbook -i hosts.ini kvm-playbook.yml -u root -e "cloudbr0_ip=10.35.2.23/24 cloudbr0_gw=10.5.2.1 dns_servers=8.8.8.8,1.1.1.1 cloudbr1_ip=10.35.5.61/24"

To execute selected roles only, use the --tags option:

For the KVM installation role:

ansible-playbook kvm-playbook.yml -i  hosts.ini -u root --tags "kvm"

For the Cockpit installation role:

ansible-playbook kvm-playbook.yml -i  hosts.ini -u root --tags "cockpit"

For network configuration:

ansible-playbook kvm-playbook.yml -i  hosts.ini -u root --tags "network" -e "cloudbr0_ip=10.35.2.23/24 cloudbr0_gw=10.5.2.1 dns_servers=8.8.8.8,1.1.1.1 cloudbr1_ip=10.35.5.61/24"

To run multiple roles (KVM and cockpit):

ansible-playbook kvm-playbook.yml -i  hosts.ini -u root --tags "kvm, cockpit"
