Virtual Machine Setup

A Virtual Machine (VM) is a software-based emulation of a physical computer. It mimics the architecture and functions of an actual computer, running its own operating system and applications. Multiple VMs can operate simultaneously on a single physical machine, each utilizing its own set of virtual hardware resources. This capability is particularly useful for engineers needing to work across different operating environments.

How We Use VMs

Section titled “How We Use VMs”

We don’t have a standard use-case for VMs at Planet Argon. Specific engineers may use VMs because of specific project set-ups, because they are working on an app that is incompabatible with their operating system, or simply out of personal preference.

  • Testing Applications: Testing Rails applications in different environments (like Windows on a Mac) without needing a separate physical machine can improve our QA process and include more developers in the workflow.
  • Isolation: VMs provide a safe, isolated environment for testing, ensuring that issues within the VM don’t impact the host machine.
  • Software Compatibility: VMs allow engineers to run software exclusive to different operating systems, like Windows-only applications on a Mac.

Choosing the Right VM Tool

Section titled “Choosing the Right VM Tool”

VirtualBox vs UTM

Section titled “VirtualBox vs UTM”
  • VirtualBox: An open-source, cross-platform tool developed by Oracle, ideal for users needing a robust solution with advanced features like shared folders, snapshot functionality, and USB device support.
  • UTM: Designed specifically for macOS and iOS, UTM offers an intuitive interface and is great for users prioritizing ease of use, especially on iOS devices.

Decision Factors

Section titled “Decision Factors”
  • Cross-Platform Support: VirtualBox is better for multi-OS compatibility.
  • Advanced Features: VirtualBox is better for functionalities like snapshots and USB support.
  • User-Friendly Interface: Opt for UTM, especially for iOS device compatibility.
  • Open-Source Preference: Both VirtualBox and UTM are viable as they are built on open-source technologies.

Setting Up a VM Using VirtualBox

Section titled “Setting Up a VM Using VirtualBox”

  1. Installation:

  2. Creating a VM:

    • Download the ISO file for the desired OS.
    • Open VirtualBox, create a new VM, allocate memory, and set up a virtual hard disk.

  3. Additional Configuration:

    • Adjust settings like CPU cores, display acceleration, and shared folders in the VM settings.

  4. Installing the Guest OS:

    • Start the VM, select the ISO file, and proceed with the OS installation.

  5. Installing Guest Additions (Optional):

    • For better integration, install VirtualBox’s Guest Additions in the VM.

Setting Up a VM Using UTM

Section titled “Setting Up a VM Using UTM”

  1. Installation:

    • Download UTM from UTM website.
    • Install the app on your macOS or iOS device.

  2. Creating a VM:

    • Download the ISO file for the guest OS.
    • Open UTM, create a new VM, allocate system RAM, and configure drives and images.

  3. Additional Configuration:

    • Customize settings based on your requirements, including display settings and network configurations.

  4. Installing the Guest OS:

    • Start the VM and proceed with the guest OS installation.

After following these steps, you will have a fully functional virtual environment, ready for your development needs. Whether you choose VirtualBox or UTM, both tools offer a reliable way to run multiple operating systems on your primary device, enhancing your development flexibility and efficiency.
