🎯 Usage

⭐ Basic Usage

Start a NetBSD 10.1 VM with default settings:

netbsd-up

🏷️ Specify NetBSD Version

netbsd-up 10.1
netbsd-up 9.3

📁 Use Local ISO File

netbsd-up /path/to/netbsd.iso

🌐 Download from Custom URL

netbsd-up https://cdn.netbsd.org/pub/NetBSD/images/10.1/NetBSD-10.1-amd64.iso

🔧 VM Management Commands

List all running VMs:

netbsd-up ps

List all VMs (including stopped):

netbsd-up ps --all

Start a stopped VM:

netbsd-up start <vm-name>

Start a VM in the background (detached):

netbsd-up start <vm-name> --detach

Stop a running VM:

netbsd-up stop <vm-name>

Restart a VM:

netbsd-up restart <vm-name>

Remove a VM:

netbsd-up rm <vm-name>

View VM logs:

netbsd-up logs <vm-name>

Follow VM logs in real-time:

netbsd-up logs <vm-name> --follow

Inspect VM details:

netbsd-up inspect <vm-name>

🖥️ Console Setup

When NetBSD boots, you’ll see the boot menu. For the best experience with the serial console:

1. 🔧 Select option 3. Drop to boot prompt
2. ⚙️ Configure console output:

   consdev com0
   boot

This enables proper console redirection to your terminal.

⚙️ Advanced Configuration

# Custom CPU, memory, and cores
netbsd-up --cpu host --memory 4G --cpus 4

# Save downloaded ISO to specific location
netbsd-up --output netbsd-10.1.iso

# Use existing disk image
netbsd-up --image vm-disk.img --disk-format qcow2

# Run VM in the background
netbsd-up --detach

# Custom port forwarding (SSH on port 2222, HTTP on port 8080)
netbsd-up --port-forward "2222:22,8080:80"

# Combine multiple options
netbsd-up --memory 8G --cpus 4 --detach --port-forward "3000:3000"

📚 Examples

⭐ Default NetBSD VM

netbsd-up

Starts NetBSD 10.1 with 2 CPU cores and 2GB RAM.

🚀 High-Performance Setup

netbsd-up --cpus 8 --memory 8G --cpu host --detach

🌐 Custom Port Forwarding

# SSH on port 2222, web server on port 8080
netbsd-up --port-forward "2222:22,8080:80"

# Development setup with multiple ports
netbsd-up --port-forward "3000:3000,5432:5432" --detach

💾 Development Environment with Persistent Disk

# Create a disk image first
qemu-img create -f qcow2 netbsd-dev.qcow2 20G

# Start VM with the disk
./main.ts --image netbsd-dev.qcow2 --disk-format qcow2

🔢 Specific versions

netbsd-up 10.1
netbsd-up 9.4

🔄 Background Operations

# Start VM in background
netbsd-up --detach

# Start existing VM in background
netbsd-up start my-vm --detach

# Monitor VM logs
netbsd-up logs my-vm --follow

🔧 VM Management Examples

# List all running VMs
netbsd-up ps

# List all VMs including stopped ones
netbsd-up ps --all

# Start a specific VM by name
netbsd-up start my-netbsd-vm

# Start a VM in the background
netbsd-up start my-netbsd-vm --detach

# Stop a running VM
netbsd-up stop my-netbsd-vm

# Restart a VM
netbsd-up restart my-netbsd-vm

# Get detailed information about a VM
netbsd-up inspect my-netbsd-vm

# Remove a VM from the database
netbsd-up rm my-netbsd-vm

# View VM logs
netbsd-up logs my-netbsd-vm

# Follow VM logs in real-time
netbsd-up logs my-netbsd-vm --follow

🌐 Networking

The VM supports flexible networking configurations:

🔌 Default Networking

• 🌐 QEMU’s user-mode networking (no special privileges required)
• 🔑 No default port forwarding (use --port-forward for specific needs)

🔧 Custom Port Forwarding

Use the --port-forward option to map host ports to guest ports:

# SSH access on port 2222
netbsd-up --port-forward "2222:22"

# Multiple port mappings
netbsd-up --port-forward "2222:22,8080:80,3000:3000"

🌉 Bridge Networking

For advanced networking, use bridge mode (requires sudo):

netbsd-up --bridge br0

📋 Version Format

NetBSD-UP recognizes version strings in the format:

• 🔢 MAJOR.MINOR (e.g., 10.1, 9.3)

⚡ The tool automatically constructs the download URL for the official NetBSD release ISO.

⚙️ Default Settings

• 🏷️ NetBSD Version: 10.1
• 🖥️ CPU: host (uses host CPU features)
• 💾 Memory: 2GB
• ⚡ CPU Cores: 2
• 💿 Disk Format: raw
• 💾 Disk Size: 20GB (when creating new disk images)
• 🌐 Network: User-mode with SSH forwarding
• 🏷️ VM Names: Auto-generated unique names using random words

💾 Data Storage

NetBSD-UP uses a SQLite database (~/.netbsd-up/state.sqlite) to track virtual machine states and configurations. The database stores:

• VM names and unique identifiers
• CPU, memory, and disk configurations
• Network settings (bridge, MAC addresses, port forwarding)
• Current status (RUNNING, STOPPED) with timestamps
• Creation and update timestamps
• Process IDs for running VMs
• Log file locations for each VM

📊 VM Logging

All VM output is automatically logged to ~/.netbsd-up/logs/<vm-name>.log. You can:

• View logs: netbsd-up logs <vm-name>
• Follow logs in real-time: netbsd-up logs <vm-name> --follow
• Access logs directly from the filesystem
