Pavilion (AI PC) Configuration#

What Was Established#

The Pavilion machine uses a USB-based or specific Ethernet interface (enx6c1f7197a66) that occasionally fails to bring the link up automatically on boot.

Current Configuration#

Netplan Configuration#

Ensure /etc/netplan/01-netcfg.yaml is correctly configured with the active interface name and permissions are set to 600.

network:
  version: 2
  ethernets:
    enx6c1f7197a66:
      dhcp4: true

Apply with:

sudo chmod 600 /etc/netplan/01-netcfg.yaml
sudo netplan apply

Boot-time Interface Fix#

If the interface remains DOWN after reboot, use a systemd service to force the link up.

Ollama Configuration#

What Was Established#

Ollama is used as the primary model backend across the fleet. The configuration focuses on making the API accessible to other nodes (like the T480 orchestrator) and running models like Gemma 4.

Key Decisions#

To allow remote access from other machines in the homelab (e.g., from a Docker container or another PC), the Ollama service must be configured to listen on all network interfaces, not just localhost.
