- Tracked v1.0.1 security improvements
- Created comprehensive CHANGELOG.md for system_info role
- Documented v1.0.0 initial release
- Tracked v1.0.1 critical bug fixes (block-level failed_when, Jinja2 templates, OS variables)
### ROADMAP.md Files
- Created detailed ROADMAP.md for deploy_linux_vm role
- Version 1.1.0: Security & compliance hardening (Q1 2026)
- Version 1.2.0: Multi-distribution support (Q2 2026)
- Version 1.3.0: Advanced features (Q3 2026)

- Version 2.0.0: Visualization & reporting (Q4 2026)
## Error Handling Enhancements
### deploy_linux_vm Role - Block/Rescue/Always Pattern
- Wrapped deployment tasks in comprehensive error handling block
- Block section:
- Pre-deployment VM name collision check
- Enhanced IP address acquisition with better error messages
- Descriptive failure messages for troubleshooting
- Rescue section (automatic rollback):
- Diagnostic information gathering
- VM status checking
- Attempted console log capture
- Automatic VM destruction and cleanup
- Disk image removal (primary, LVM, cloud-init ISO)
- Detailed troubleshooting guidance
- Always section:
- Deployment logging to /var/log/ansible-vm-deployments.log
- Success/failure tracking
- Improved task FQCNs (ansible.builtin.*)
## Handlers Implementation
### deploy_linux_vm Role - Complete Handler Suite
- VM Lifecycle Handlers:
- restart vm, shutdown vm, destroy vm
- Cloud-Init Handlers:
- regenerate cloud-init iso (full rebuild and reattach)
- Storage Handlers:
- refresh libvirt storage pool
- resize vm disk (with safe shutdown/start)
- Network Handlers:
- refresh network configuration
- restart libvirt network
- Libvirt Daemon Handlers:
- restart libvirtd, reload libvirtd
- Cleanup Handlers:
- cleanup temporary files
- remove cloud-init iso
- Validation Handlers:
- validate vm status
- check connectivity
## Impact
### Security
- Eliminates hardcoded secrets from version control
- Implements industry best practices for secret management
- Provides clear guidance for secure deployment
### Maintainability
- CHANGELOGs enable version tracking and change auditing
- ROADMAPs provide clear development direction and prioritization
- Comprehensive error handling reduces debugging time
- Handlers enable modular, reusable state management
### Reliability
- Automatic rollback prevents partial deployments
- Comprehensive error messages reduce MTTR
- Handlers ensure consistent state management
- Better separation of concerns
### Compliance
- Aligns with CLAUDE.md security requirements
- Implements proper secrets management per organizational policy
- Provides audit trail through changelogs
