# Proxmox Production VM - Optimized Configuration

Based on your Proxmox hardware, here's the optimized VM configuration:

## 🖥️ Your Proxmox Hardware

- **CPU:** 24 cores (2x Intel Xeon E5645 @ 2.40GHz)
- **RAM:** 94.27 GiB total (45% used)
- **Storage:** pve-main (NVMe)
- **Network:** vmbr1

## ⚙️ Optimized VM Settings

### VM Configuration (VM-202)
```yaml
VM ID: 202
Name: DevMatrix-Prod
CPU: 6 cores (dedicated)
Sockets: 2 (matches your dual-CPU setup)
RAM: 16GB (no ballooning)
Disk: 150GB (NVMe with TRIM)
Network: vmbr1 (firewall enabled)
NUMA: Enabled (optimal for dual-socket)
CPU Priority: 2048 (high priority)
Auto-start: Yes
Boot Order: scsi0
```

### Why These Settings?

| Setting | Value | Reason |
|---------|-------|--------|
| **6 CPU cores** | Not too few, not too many | Leaves plenty for other VMs |
| **2 sockets** | Matches your hardware | Better NUMA performance |
| **16GB RAM** | 17% of total | Guaranteed memory, no swapping |
| **150GB NVMe** | Fast storage | Plenty for app + logs + backups |
| **vmbr1** | Your network | No VLAN needed |
| **TRIM enabled** | SSD optimization | Prevents performance degradation |
| **High CPU priority** | 2048 vs default 1024 | Production gets priority |

## 🚀 Quick Start

### 1. Run VM Creation Script

```bash
# SSH into Proxmox host, then:
curl -fsSL https://git.lemonlink.eu/devmatrix/devmatrix-scripts/raw/branch/main/proxmox/create-production-vm.sh | sudo bash
```

This will:
- Download Ubuntu 22.04 cloud image
- Create VM-201 with optimized settings
- Configure networking (192.168.5.211)
- Start the VM

### 2. Complete Setup

```bash
# SSH into the new VM
ssh devmatrix@192.168.5.211

# Run setup
curl -fsSL https://git.lemonlink.eu/devmatrix/devmatrix-scripts/raw/branch/main/proxmox/setup-production-vm.sh | sudo bash
```

### 3. Deploy Mission Control

```bash
# Clone repo
git clone https://git.lemonlink.eu/devmatrix/mission-control.git ~/mission-control

# Deploy
cd ~/mission-control
mc-deploy
```

## 📊 Resource Usage Estimate

After deployment, expect:
- **CPU:** 0.5-2 cores (idle to moderate load)
- **RAM:** 2-4GB (can scale to 8GB if needed)
- **Disk:** ~5GB initial, grows with data

**Plenty of headroom for growth!**

## 🔧 Manual Configuration (if needed)

If you prefer manual setup in Proxmox GUI:

1. **Create VM:**
   - VM ID: 201
   - Name: DevMatrix-Prod
   - Resource: pve-main (NVMe)

2. **OS:**
   - Use CD/DVD: Ubuntu 22.04 ISO
   - Or use cloud-init image

3. **System:**
   - Machine: q35
   - SCSI Controller: VirtIO SCSI single
   - BIOS: OVMF (UEFI)
   - QEMU Agent: Yes

4. **CPU:**
   - Sockets: 2
   - Cores: 3 per socket
   - Type: host
   - NUMA: Yes

5. **Memory:**
   - Size: 16384 MB
   - Ballooning: No

6. **Network:**
   - Bridge: vmbr1
   - Model: VirtIO
   - Firewall: Yes

7. **Disk:**
   - Storage: pve-main
   - Size: 150GB
   - Discard: Yes
   - SSD emulation: Yes
   - iothread: Yes

## ✅ Validation Checklist

After VM creation, verify:
- [ ] VM starts without errors
- [ ] Network reachable: `ping 192.168.5.211`
- [ ] SSH working: `ssh devmatrix@192.168.5.211`
- [ ] QEMU agent running: `qm agent $VM_ID ping`
- [ ] TRIM working: `fstrim -av` (in VM)

## 🔄 Post-Deployment

Once Mission Control is running:

```bash
# Check status
mc-status

# Monitor resources
htop

# View logs
mc-logs

# Check disk usage
df -h
```

## 🆘 Troubleshooting

### VM won't start
```bash
# Check for errors
qm start $VM_ID --verbose
journalctl -xe | grep pvedaemon
```

### No network
```bash
# Check bridge
ip addr show vmbr1

# Check VM network
qm config $VM_ID
```

### Storage issues
```bash
# Check available space
pvesm status

# Check disk
qm disk list $VM_ID
```

## 📈 Future Scaling

If you need more resources later:

```bash
# Add more CPU
qm set 202 --cores 8

# Add more RAM
qm set 202 --memory 24576

# Resize disk
qm disk resize 202 scsi0 +50G
```

All changes can be done live without downtime!
