# 01 - Proxmox & VM Passthrough — Home
**Purpose:** Complete setup guide for Proxmox VM passthrough with optimal resource allocation.

## Topics Covered

- **GPU Passthrough:** Configure AMD/Intel/NVIDIA GPUs for VM access
- **NVMe Passthrough:** Pass NVMe drives to VMs for high I/O performance
- **USB Passthrough:** Connect USB devices (webcams, dongles, etc.) to VMs
- **Networking:** Bridge networking, VLANs, and virtual switches
- **Resource Allocation:** CPU cores, RAM, and storage optimization

## Quick Start

### Create a VM with GPU Passthrough

```bash
# Step 1: Find available GPU
rocm-smi | grep "GPU"  # AMD
nvidia-smi             # NVIDIA

# Step 2: Create VM with GPU passthrough
qm create 100 --name qwen-vm --memory 32768 --cores 8 --arch x86_64
qm set 100 --hostpci0=0000:03:00.0,pcie=1,x-vga=1  # AMD example

# Step 3: Install QEMU Guest Agent
apt install qemu-guest-agent

# Step 4: Reboot VM
qm reboot 100
```

## Best Practices

1. **IOMMU Groups:** Always check if devices are in separate IOMMU groups
2. **VFIO Modules:** Ensure `vfio-pci` module is loaded before boot
3. **PCIe Hotplug:** Disable for stability unless required
4. **Memory Ballooning:** Disable in VM for consistent performance
