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)

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

# 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

# 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

# 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:

# Check status
mc-status

# Monitor resources
htop

# View logs
mc-logs

# Check disk usage
df -h

🆘 Troubleshooting

VM won't start

# Check for errors
qm start $VM_ID --verbose
journalctl -xe | grep pvedaemon

No network

# Check bridge
ip addr show vmbr1

# Check VM network
qm config $VM_ID

Storage issues

# Check available space
pvesm status

# Check disk
qm disk list $VM_ID

📈 Future Scaling

If you need more resources later:

# 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!
