Introduction

Once your Ansible control node is configured, deploying a virtual machine on Nutanix AHV is just a few lines of YAML away. This article walks through an enterprise-ready playbook to launch AHV VMs using the Nutanix Ansible collection. We’ll cover options for CPU, memory, networks, and storage, and how to make the playbook reusable.

Diagram: VM Deployment Workflow

Step 1: Define Inventory

Use inventory.yml as in Part 1:

all:
  hosts:
    localhost:
      ansible_connection: local

Step 2: Define Credentials File

Already encrypted from Part 1:

nutanix_pc_hostname: prism.example.com
nutanix_pc_port: 9440
nutanix_username: admin
nutanix_password: S3cure!
validate_certs: false

Step 3: Create Your VM Deployment Playbook

- name: Deploy AHV VM on Nutanix
  hosts: localhost
  gather_facts: false
  collections:
    - nutanix.ncp
  vars_files:
    - nutanix_credentials.yml
  tasks:
    - name: Deploy application VM
      nutanix.ncp.vms:
        state: present
        name: app-server-01
        cluster_name: prod-cluster
        memory_size_mib: 8192
        num_vcpus_per_socket: 2
        num_sockets: 1
        boot_type: UEFI
        vm_disks:
          - disk_size_mib: 20480
            storage_container: default-container
        vm_nics:
          - subnet_name: vlan10
        guest_tools:
          agent_enabled: true

Step 4: Add Extra Configs (Optional)

        description: "App VM from Ansible"
        categories:
          - name: AppRole
            value: Web
        metadata:
          created_by: ansible

Step 5: Run the Playbook

ansible-playbook deploy_vm.yml --ask-vault-pass -i inventory.yml

Tips for Production Readiness

• Use tags for metadata control
• Store template inputs in group_vars/ or host_vars/
• Validate inputs with Ansible conditions or when:
• Store VM specs in separate YAML vars for repeatability

Summary

This playbook demonstrates how to launch a production-grade Nutanix VM using Ansible. By defining resources declaratively, you’re able to standardize provisioning and reduce admin overhead. Future posts will focus on snapshotting, networking, and scaling VMs dynamically.
