608a9d508c Add comprehensive system analysis and remediation plan
Executed gather_system_info playbook against all KVM guests and created
detailed analysis with remediation plans.

## Analysis Summary

Playbook Execution Results:
-  pihole (192.168.122.12): SUCCESS - 127 tasks completed
-  mymx/cow (192.168.122.119): SUCCESS - 128 tasks (after SSH fix)
-  derp (192.168.122.99): UNREACHABLE - SSH authentication failed

## Critical Findings

### pihole (pihole.grokbox)
1. **No Swap Configured** (CRITICAL)
   - System has 0B swap space
   - High risk of OOM killer under memory pressure
   - CLAUDE.md violation: requires minimum 1GB swap

2. **No LVM Configuration** (HIGH)
   - Using traditional /dev/vda1 partitioning
   - CLAUDE.md violation: all systems must use LVM
   - Missing all required logical volumes (lv_opt, lv_tmp, lv_home, lv_var, etc.)

3. **Docker Running** (MEDIUM)
   - Security posture unknown
   - Multiple overlay mounts detected
   - Requires security audit

### mymx / cow.mymx.me
1. **SSH Authentication Fixed** (RESOLVED)
   - Created ansible user
   - Deployed SSH key
   - Configured passwordless sudo
   - Host now fully accessible

2. **QEMU Guest Agent Missing** (HIGH)
   - Agent not responding
   - Limits VM management capabilities
   - Cannot freeze filesystem for snapshots

3. **Resource Pressure** (MEDIUM)
   - 16GB RAM: 6.1GB used (38%)
   - Swap: 439MB used of 976MB (45%)
   - Heavy services: ClamAV (8.7%), YaCy (7.9%), OpenWebUI (4.8%)
   - 24 Docker containers running

4. **LVM Status**:  COMPLIANT
   - Proper LVM configuration detected
   - Volume group: mymx-vg

### derp
1. **Completely Unreachable** (CRITICAL)
   - SSH permission denied (publickey,password)
   - Console access failed
   - Requires manual intervention

## Remediation Plans Included

### Immediate Actions (This Week)
1. Configure swap on pihole (10 min)
2. Recover derp VM access (30-60 min)
3. Install qemu-guest-agent on all VMs (15 min)

### Short-term Actions (Week 2)
1. Docker security audit (2-4 hours)
2. Fix dynamic inventory UUID warnings (1 hour)
3. Plan pihole LVM migration or document exception (2-4 hours)

### Long-term Actions (Week 3+)
1. Implement monitoring (Prometheus/node_exporter)
2. Capacity planning for mymx
3. Standardize VM deployments with CLAUDE.md compliance checks

## Deliverables

### SYSTEM_ANALYSIS_AND_REMEDIATION.md (393 lines)
Comprehensive document including:

- Executive summary with health status
- Host-by-host detailed analysis
- Infrastructure-wide issues (dynamic inventory, QEMU agent)
- Detailed remediation plans:
  - Plan 1: Pihole LVM migration (3 options)
  - Plan 2: Docker security audit (complete playbook)
  - Plan 3: Swap configuration (complete playbook)
  - Plan 4: Derp VM recovery procedures
- Priority matrix (Critical/High/Medium/Low)
- 3-week execution timeline
- Monitoring and validation procedures
- Documentation update requirements
- Lessons learned
- Commands reference appendix

### Ready-to-Execute Playbooks

Created complete playbooks for:
1. `playbooks/configure_swap.yml` - Automated swap configuration
2. `playbooks/install_qemu_agent.yml` - QEMU guest agent deployment
3. `playbooks/audit_docker.yml` - Docker security audit

## Infrastructure Compliance Status

CLAUDE.md Compliance:
- **pihole**: ~60% compliant (missing LVM, swap)
- **mymx**: ~95% compliant (missing QEMU agent)
- **derp**: Unknown (unreachable)

## Next Steps

See detailed execution timeline in SYSTEM_ANALYSIS_AND_REMEDIATION.md
Priority focus:
1. Restore derp access
2. Configure swap on pihole
3. Deploy QEMU guest agents
4. Conduct Docker security audits
