KVM Playbook Instructions

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.

hosts.ini Inventory File Explanation

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

Applying the Playbook to Hypervisors

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"

Running Specific Roles

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"
