VM Image Creation Guide for Nanite

This document provides a comprehensive guide for creating VMware and VirtualBox virtual machine images for the Nanite Linux distribution. These VM images will allow users to quickly deploy and test Nanite without having to perform a full installation.

Prerequisites

Before creating VM images, ensure you have:

  1. A successfully built and tested Nanite ISO image
  2. Sufficient disk space (at least 40GB free)
  3. VMware Workstation/Player and/or VirtualBox installed
  4. Basic familiarity with virtual machine operations

General Approach

The process for creating VM images involves:

  1. Installing Nanite in a virtual machine
  2. Configuring the installed system for optimal VM performance
  3. Cleaning up the system to reduce image size
  4. Exporting the VM in the appropriate format

Creating a VirtualBox Image

Step 1: Set Up a New Virtual Machine

# Create a new virtual machine
VBoxManage createvm --name "Nanite" --ostype Debian_64 --register
 
# Configure VM resources (adjust based on target audience)
VBoxManage modifyvm "Nanite" --memory 4096 --cpus 2 --vram 128 --graphicscontroller vmsvga
VBoxManage modifyvm "Nanite" --accelerate3d on --clipboard bidirectional --draganddrop bidirectional
 
# Create and attach a virtual hard disk (20GB)
VBoxManage createhd --filename "Nanite.vdi" --size 20480
 
# Set up storage controllers
VBoxManage storagectl "Nanite" --name "SATA Controller" --add sata --controller IntelAHCI
VBoxManage storageattach "Nanite" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium "Nanite.vdi"
VBoxManage storagectl "Nanite" --name "IDE Controller" --add ide
VBoxManage storageattach "Nanite" --storagectl "IDE Controller" --port 0 --device 0 --type dvddrive --medium /path/to/nanite-ai-linux.iso
 
# Configure network
VBoxManage modifyvm "Nanite" --nic1 nat

Step 2: Install Nanite

# Start the VM
VBoxManage startvm "Nanite"

During the installation process:

  1. Boot from the ISO and select “Install Nanite”
  2. Follow the installation wizard
  3. When prompted for partitioning, use the entire disk
  4. Install GRUB to the MBR
  5. Complete the installation and reboot

Step 3: Post-Installation Configuration

After installation, log in to the system and perform these optimizations:

# Update the system
sudo apt update
sudo apt upgrade -y
 
# Install VirtualBox Guest Additions
sudo apt install -y virtualbox-guest-utils virtualbox-guest-x11
 
# Configure for VM environment
sudo systemctl enable vboxadd-service
sudo systemctl start vboxadd-service
 
# Optimize for VM use
sudo apt install -y haveged
sudo systemctl enable haveged

Step 4: System Cleanup

Before exporting, clean up the system to reduce image size:

# Remove installation logs and temporary files
sudo apt clean
sudo apt autoremove -y
sudo rm -rf /var/log/*.log /var/log/*/*.log
sudo rm -rf /var/cache/apt/*
sudo rm -rf /tmp/*
 
# Clear bash history
cat /dev/null > ~/.bash_history
history -c
 
# Shutdown the VM
sudo shutdown -h now

Step 5: Export VirtualBox Image

With the VM shut down, export it to a distributable format:

# Compact the VDI to reduce size
VBoxManage modifymedium disk "Nanite.vdi" --compact
 
# Export to OVA format (most portable)
VBoxManage export "Nanite" --output "Nanite-VirtualBox.ova" --ovf20 --manifest

Creating a VMware Image

Step 1: Set Up a New Virtual Machine

Using VMware Workstation/Player:

  1. Select “Create a New Virtual Machine”
  2. Choose “Custom (advanced)” setup
  3. Select “I will install the operating system later”
  4. Select “Linux” as the guest OS and “Debian 64-bit” as the version
  5. Name the VM “Nanite”
  6. Allocate 4GB RAM and 2 CPU cores
  7. Create a new virtual disk (20GB, single file)
  8. Customize hardware:
    • Add the Nanite ISO to the CD/DVD drive
    • Enable 3D acceleration if available
    • Configure network as NAT

Step 2: Install Nanite

  1. Start the VM
  2. Boot from the ISO and select “Install Nanite”
  3. Follow the installation wizard
  4. When prompted for partitioning, use the entire disk
  5. Install GRUB to the MBR
  6. Complete the installation and reboot

Step 3: Post-Installation Configuration

After installation, log in to the system and perform these optimizations:

# Update the system
sudo apt update
sudo apt upgrade -y
 
# Install VMware Tools
sudo apt install -y open-vm-tools open-vm-tools-desktop
 
# Configure for VM environment
sudo systemctl enable open-vm-tools
sudo systemctl start open-vm-tools
 
# Optimize for VM use
sudo apt install -y haveged
sudo systemctl enable haveged

Step 4: System Cleanup

Before exporting, clean up the system to reduce image size:

# Remove installation logs and temporary files
sudo apt clean
sudo apt autoremove -y
sudo rm -rf /var/log/*.log /var/log/*/*.log
sudo rm -rf /var/cache/apt/*
sudo rm -rf /tmp/*
 
# Clear bash history
cat /dev/null > ~/.bash_history
history -c
 
# Shutdown the VM
sudo shutdown -h now

Step 5: Export VMware Image

With the VM shut down, export it to a distributable format:

  1. In VMware, select the VM
  2. Go to File > Export to OVF
  3. Name the export “Nanite-VMware”
  4. Select a destination folder
  5. Click “Save” to export

Alternatively, use the command line:

# For VMware Workstation
"C:\Program Files (x86)\VMware\VMware Workstation\OVFTool\ovftool.exe" "path\to\Nanite.vmx" "Nanite-VMware.ova"
 
# For VMware Player on Linux
ovftool /path/to/Nanite.vmx Nanite-VMware.ova

Optimizing VM Images

To ensure the best user experience, consider these optimizations:

Performance Optimizations

# Disable unnecessary services
sudo systemctl disable bluetooth.service
sudo systemctl disable cups.service
sudo systemctl disable avahi-daemon.service
 
# Configure swappiness for better VM performance
echo "vm.swappiness=10" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
 
# Optimize filesystem for SSD
sudo sed -i 's/errors=remount-ro/errors=remount-ro,noatime,nodiratime/' /etc/fstab

AI Component Optimizations

# Ensure AI services start automatically
sudo systemctl enable ollama.service
sudo systemctl enable nanite-assistant.service
 
# Pre-download smaller models for immediate use
ollama pull phi3:mini

User Experience Enhancements

# Create a welcome screen
cat > /etc/profile.d/nanite-welcome.sh << EOF
#!/bin/bash
echo "Welcome to Nanite VM!"
echo "This virtual machine contains a complete Nanite AI Linux environment."
echo "AI services are pre-configured and ready to use."
echo ""
echo "For help, type: less /usr/share/doc/nanite/README.md"
EOF
chmod +x /etc/profile.d/nanite-welcome.sh
 
# Add desktop shortcuts for common AI tools
mkdir -p /etc/skel/Desktop
cp /usr/share/applications/nanite-assistant.desktop /etc/skel/Desktop/
cp /usr/share/applications/nanite-image-generator.desktop /etc/skel/Desktop/
