Node configuration — network bridge, storage pools, post-install tweaks, and update channels.

🏗️ Proxmox Host: Node Configuration

[!NOTE] This document covers the Proxmox VE node-level configuration: network bridge, storage pool definitions, post-install tweaks, and update channels. For physical hardware specs, see hardware.md.

Node Identity

Property	Value
Hostname	`jaysync-lab`
Management IP	`192.168.1.100`
Web UI	`https://192.168.1.100:8006`
Remote Access	Tailscale (`100.87.172.121`)

Proxmox Software Versions

Component	Version
Proxmox VE	9.2.3
Kernel	7.0.6-2-pve
Base OS	Debian GNU/Linux 13 (trixie)
QEMU	11.0.0
LXC	7.0.0

Network Configuration

Linux Bridge: `vmbr0`

All LXC containers and VMs use the vmbr0 virtual bridge, which is bound to the host's physical Realtek GbE NIC (r8169 driver).

auto vmbr0
iface vmbr0 inet static
    address  192.168.1.100/24
    gateway  192.168.1.1
    bridge-ports <physical-nic>
    bridge-stp   off
    bridge-fd    0

[!TIP] To inspect the live network config on the node: cat /etc/network/interfaces

Bridge design rationale:

Single-bridge flat LAN keeps routing simple for a home environment.
All containers receive IPs in 192.168.1.0/24 directly visible to the home router.
No internal VLAN segmentation (intentional — complexity not warranted at current scale).

Storage Pool Definitions

Three storage pools are configured in Proxmox. Pool selection for new workloads follows the tier-matching principle: fast storage for I/O-sensitive workloads, vault for bulk data.

Pool	Backend	Device	Capacity	Purpose
`local`	Directory (ext4)	SSD	~94GB	ISOs, CT templates, Proxmox backups
`local-lvm`	LVM-Thin	SSD	~320GB	VM/CT disk images (thin-provisioned)
`vault`	Directory (ext4)	HDD	~916GB	Media data, snapshots, bulk backups

Mount point: vault is mounted at /mnt/pve/vault.

[!TIP] To check live pool status and usage: pvesm status

Post-Installation Configuration

1. Subscription Nag Removal

The Proxmox community no-subscription repository was added to remove the enterprise-repo nag:

# /etc/apt/sources.list.d/pve-no-subscription.list
deb http://download.proxmox.com/debian/pve trixie pve-no-subscription

2. Tailscale (Bare-Metal VPN)

Tailscale is installed directly on the Proxmox host — not inside an LXC — so the management interface (8006) remains reachable remotely even if internal containers fail.

See tailscale-routing.md for the MagicDNS conflict fix and full rationale.

3. Intel iGPU Passthrough (for Media Stack)

The Intel HD Graphics 530 (i915) is passed through to CT 104 (media-stack) for hardware-accelerated video transcoding. The Proxmox host exposes /dev/dri which is bind-mounted into the container.

# Verify DRM render node is available on the host
ls -la /dev/dri/

Update Procedure

apt update && apt dist-upgrade

Proxmox VE updates come via the pve-no-subscription repository. Always review release notes before applying a major version bump.
