VMID 6000 Network Fix - Complete

Date: 2026-01-22
VMID: 6000 (fabric-1)
IP Address: 192.168.11.113
Status: ✅ FIXED (temporary) | ⚠️ RESTART REQUIRED (persistent)

---

Problem

VMID 6000 was showing "Network is unreachable" after IP reassignment from 192.168.11.112 to 192.168.11.113.

---

Root Cause

1. Interface State: eth0 was in state DOWN
2. Missing IP: No IPv4 address assigned to eth0 (only IPv6 link-local)
3. No Default Route: Gateway route was missing

---

Fix Applied

Step 1: Bring Interface UP

pct exec 6000 -- ip link set eth0 up

✅ Result: Interface is now UP

Step 2: Assign IP Address

pct exec 6000 -- ip addr add 192.168.11.113/24 dev eth0

✅ Result: IPv4 address assigned

Step 3: Add Default Route

pct exec 6000 -- ip route add default via 192.168.11.1 dev eth0

✅ Result: Default route configured

---

Current Status

Interface Status

• ✅ eth0 is UP
• ✅ IPv4 address: 192.168.11.113/24 assigned
• ✅ Default route: via 192.168.11.1

Connectivity

• ✅ Gateway (192.168.11.1): Reachable
• ⚠️ Note: This fix is temporary - IP assignment will be lost on container restart

---

Persistent Fix Required

The IP address assignment is temporary. For a persistent fix, the container needs to be restarted so Proxmox applies the network configuration from pct config.

Recommended Action

# On Proxmox host (r630-01)
pct stop 6000
pct start 6000

After restart, Proxmox will automatically:

• Bring the interface UP
• Assign the IP address (192.168.11.113/24)
• Configure the default route (via 192.168.11.1)

---

Verification

After restart, verify:

# Check interface
pct exec 6000 -- ip addr show eth0

# Check routing
pct exec 6000 -- ip route show

# Test connectivity
pct exec 6000 -- ping -c 2 192.168.11.1

---

Summary

Status: ✅ TEMPORARY FIX APPLIED

• Interface is UP
• IP address assigned
• Gateway reachable
• Action Required: Restart container for persistent fix

---

Next Step: Restart VMID 6000 to make the network configuration persistent.
