# Proxmox

## What it is

Proxmox VE is the bare-metal hypervisor running in the homelab, hosting virtual machines and LXC containers for all homelab services. It provides the compute substrate under Authentik, DNS stack (Knot + Pi-hole), OB1 (Supabase + pgvector), the GitHub Actions self-hosted runner (ustest1), and future services. Proxmox's VM/LXC flexibility allows mixing full VMs (for services needing kernel isolation) with lightweight LXCs (for simpler services).

## Current state

Active. Key guests running on Proxmox:
- **ustest1** — Self-hosted GitHub Actions runner for PBS CI/CD (`pbsii-cicd-pipeline`)
- **DNS stack** — Knot DNS primary + secondary, Pi-hole (split-horizon `.herbylab.dev`)
- **Authentik** — SSO/IdP for homelab services
- **`homelab-postgres`** — pgvector:pg17 container hosting the consolidated `petalbrain` DB (wiki/ob1/trellis schemas) — the substrate for OB1 and the MCP servers
- **Traefik VM 102** (`10.0.21.181`) — homelab ingress with the `*.herbylab.dev` wildcard
- **PBS LXC 110** — Proxmox Backup Server (Debian 12); daily backups to local datastore, weekly rsync to NAS
- **us-test-authy (VM 100)** — recovered to static `10.0.21.207`; runs Claude Desktop / Dispatch
- **herbydev** — Primary dev workstation VM (promoted from us-test-authy)

VLAN scheme renumbered in May 2026: VID 11 (lab network), VID 21 (private network); OpenWrt switch chip aligned to bridge VID assignment. (Note: DaVinci Resolve runs on the separate `herbyeos` Endeavour tower, not on Proxmox.)

## Where it lives

- Physical homelab hardware (specific host/model not documented in sources)
- Managed via Proxmox web UI and CLI
- Network: OpenWrt VLAN-segmented switch, VLANs 11/21
