### Swap Configuration Test (pihole)
```
Before: Swap: 0B 0B 0B
After:  Swap: 2.0Gi 0B 2.0Gi

$ free -h
              total        used        free      shared  buff/cache   available
Mem:           1.9Gi       386Mi        86Mi       8.0Mi       1.6Gi       1.5Gi
Swap:          2.0Gi          0B       2.0Gi

$ swapon --show
NAME      TYPE SIZE USED PRIO
/swapfile file   2G   0B   -2

$ cat /etc/fstab | grep swap
/swapfile none swap sw 0 0
```

### QEMU Agent Test (pihole)
```
$ systemctl status qemu-guest-agent
● qemu-guest-agent.service - QEMU Guest Agent
   Loaded: loaded (/lib/systemd/system/qemu-guest-agent.service; static)
   Active: active (running)

$ qemu-ga --version
QEMU Guest Agent 10.0.3

$ ls -la /dev/vport2p1
crw------- 1 root root 245, 1 Oct 19 14:22 /dev/vport2p1

Status: Fully operational
```

### SSH Connectivity Test (mymx)
```
$ ansible mymx -m ping
mymx | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
```

cc21e89a78 Add playbook structure, master playbook, and collections requirements 
Implement standardized playbook organization with master orchestrator
and Ansible collections requirements for extended functionality.

Playbook Structure:
playbooks/
├── gather_system_info.yml    # System inventory gathering
├── deploy_vm.yml             # VM deployment (placeholder)
├── security_audit.yml        # Security compliance checking (placeholder)
├── maintenance.yml           # Routine maintenance tasks (placeholder)
├── backup.yml                # Backup operations (placeholder)
└── disaster_recovery.yml     # DR procedures (placeholder)

Master Playbook (site.yml):
- Entry point for all infrastructure operations
- Import structure for modular playbook organization
- Tag-based execution for selective operations
- Pre-flight checks and validations
- Comprehensive documentation and usage examples

Collections Requirements (collections/requirements.yml):
- community.general: Essential utilities and modules
- community.libvirt: KVM/libvirt management
- ansible.posix: POSIX system administration
- amazon.aws: AWS infrastructure management (optional)
- Community versions for open-source compatibility

Implemented Playbooks:

1. gather_system_info.yml:
   - Comprehensive system information gathering
   - Uses system_info role
   - Statistics export to ./stats/machines/
   - Health checks and validation
   - Tag support: install, gather, export, validate, health-check

2. Placeholder Playbooks (documented structure):
   - deploy_vm.yml: VM provisioning with deploy_linux_vm role
   - security_audit.yml: CIS benchmark compliance checking
   - maintenance.yml: Updates, cleanup, optimization
   - backup.yml: Backup operations orchestration
   - disaster_recovery.yml: DR procedures and testing

site.yml Master Playbook Features:
- Central orchestration point
- Import-based playbook inclusion
- Tag inheritance and selective execution
- Environment-aware (development, staging, production)
- Pre-flight validation checks
- Error handling and rollback support
- Comprehensive inline documentation

Usage Examples:
```bash
# Run all playbooks
ansible-playbook site.yml

# Run specific playbook
ansible-playbook site.yml --tags gather_info

# Gather system information only
ansible-playbook playbooks/gather_system_info.yml

# Check syntax
ansible-playbook site.yml --syntax-check

# Dry run
ansible-playbook site.yml --check

# Limit to specific hosts
ansible-playbook site.yml -l webservers
```

Collections Management:
- Install: ansible-galaxy collection install -r collections/requirements.yml
- Update: ansible-galaxy collection install -r collections/requirements.yml --upgrade
- Location: ./collections/ (local) and ~/.ansible/collections (user)
- Version pinning for stability
- Community alternatives for RHEL-free deployments

CLAUDE.md Compliance:
✅ Playbooks in ./playbooks/ directory
✅ Master playbook (site.yml) at root
✅ Tag-based execution support
✅ Modular organization with import_playbook
✅ Collections requirements documented
✅ Clear separation: playbooks (lasting) vs plays (temporary)

Benefits:
- Standardized playbook organization
- Easy-to-navigate structure
- Tag-based selective execution
- Collection dependency management
- Scalable to 100+ playbooks
- Clear entry point (site.yml)
- Environment isolation

Next Steps:
1. Install collections: ansible-galaxy collection install -r collections/requirements.yml
2. Implement placeholder playbooks as needed
3. Add role-specific playbooks to playbooks/ directory
4. Create temporary plays in plays/ directory (per CLAUDE.md)
5. Test site.yml orchestration: ansible-playbook site.yml --check
