Proxmox Infrastructure: Matrix/Virgo-Core Cluster
Manage 3-node Proxmox VE cluster with CEPH storage, VLAN networking, and cloud-init automation.
Available Tools
Python Scripts (uv-based)
- validate_template.py - Validate template health via Proxmox API
- cluster_status.py - Cluster health metrics and node status
- check_ceph_health.py - CEPH storage pool health monitoring
- check_cluster_health.py - Comprehensive cluster diagnostics
All scripts support --help for usage. Run with: uv run tools/<script>.py
Automation Examples
- Ansible playbooks - Template creation, VLAN bridging setup
- Terraform modules - VM cloning, multi-node deployments with dual NICs
See examples/ and workflows/ for working configurations.
Core Capabilities
Template Management:
- Ubuntu/Debian cloud-init templates with virtio-scsi
- Serial console configuration for cloud images
- Proper boot order and cloud-init CD-ROM (ide2)
Network Infrastructure:

Quick Examples
Clone template to VM:
qm clone 9000 101 --name web-01
qm set 101 --ipconfig0 ip=192.168.3.100/24,gw=192.168.3.1
qm set 101 --net0 virtio,bridge=vmbr0,tag=30
qm start 101Check cluster health:
