VirtualBox is a popular open-source virtualization software that allows users to run multiple operating systems on a single physical machine. With its user-friendly interface and wide range of features, VirtualBox has become the go-to virtualization tool for many developers, testers, and IT professionals. But what exactly makes VirtualBox better than other desktop virtualization solutions like VMware Workstation or Parallels Desktop? Here are some of the key advantages of using VirtualBox.
It’s Free and Open Source
One of the biggest perks of using VirtualBox is that it is completely free to download and use, even for commercial purposes. The software is open source and developed by Oracle. So you don’t have to worry about any licensing fees or restrictions when using VirtualBox, unlike other proprietary virtualization platforms.
Being open source also means the VirtualBox codebase is continuously improved by developers from around the world. New features and bug fixes are added at a rapid pace, which helps VirtualBox stay on par with paid solutions in terms of capabilities. And if you ever need support, the VirtualBox user community is very active online.
Wide Platform Support
VirtualBox runs on a wide range of host operating systems, from Windows and macOS to Linux and Solaris. This cross-platform versatility makes VirtualBox the preferred virtualization tool for many developers who work on multiple operating systems.
The guest OS support is even more impressive. You can install nearly any x86-based OS as a guest machine in VirtualBox, including Windows, Linux, BSD, Solaris, Haiku, ReactOS, Plan 9, and more. Even some experimental operating systems like TempleOS run smoothly on VirtualBox.
So whether you need to test software across Windows, macOS, and Linux or run obscure legacy operating systems, VirtualBox has you covered better than any other virtualization software.
Excellent Virtual Networking Capabilities
Setting up virtual networks is an area where VirtualBox shines. It comes with a robust networking engine that delivers advanced networking capabilities for connecting guest VMs in flexible configurations.
You can set up isolated private networks between VMs or configure shared networks that bridge with the host’s physical network adapters. VirtualBox even supports Wi-Fi adapters for connecting VMs to wireless networks. Features like VirtualBox’s internal DHCP server, NAT forwarding, and Host-only networking provide you tons of options for customizing network access for VMs.
For teams that need to test multi-tier application stacks across replicated dev/test environments, the virtual networking flexibility of VirtualBox is extremely valuable.
Abundant Virtual Device Support
In addition to networking, VirtualBox provides excellent support for virtualized hardware devices. You can add up to 36 virtual CPUs to a VM and assign as much RAM as you want. VirtualBox includes a built-in graphics card for high-resolution displays and 3D acceleration for games.
You can easily add virtual storage controllers, disk drives, DVD drives, audio devices, serial and parallel ports, USB hubs, and PCI devices to your guest VMs. And with the Guest Additions package installed, things like shared folders, clipboard, mouse, and graphics performance get a significant boost.
So whether you need to replicate a complex production server setup or just make a lightweight VM for application testing, VirtualBox provides all the virtual hardware customization options you’ll need.
Snapshotting for Easy Rollbacks
Like most virtualization software, VirtualBox allows you to take snapshots of VM states at any point in time. This lets you easily roll back VMs to previous configurations and quickly restore clean environments.
But where VirtualBox shines is the sheer flexibility of its snapshotting capabilities. You can have multiple snapshot branches per VM for testing different configurations in parallel. Nested snapshots allow you to create snapshots of snapshots. And you can merge snapshots for permanently applying specific changes to VMs.
These advanced snapshotting features enable intricate testing workflows like multi-variant test matrix builds. Overall, it makes experimenting with software configurations and testing OS changes much quicker and safer.
Powerful CLI and Automation
For teams that need to automate VM provisioning and testing, VirtualBox offers great command-line tools. The VBoxManage utility allows you to control nearly every aspect of VirtualBox from the CLI. You can easily automate VM launches, configure hardware, take snapshots, clone VMs, and export VMs using shell scripts or configuration management tools.
This enables you to replicate complex VM environments on demand. The open API also allows you to tap into VirtualBox programmatically for automation. Large dev teams find these automation capabilities invaluable for speeding up provisioning and testing workflows.
Great for Mobile Emulation
Testing mobile applications is one area where VirtualBox shines. Its ability to emulate touchscreens and devices makes it great for Android/iOS app testing.
By pairing VirtualBox with the Android x86 project, you can build virtual Android devices for testing mobile apps. Popular Android emulators like Genymotion and AndY also use VirtualBox under the hood. For iOS, you can run Hackintosh VMs to build virtual Macs for compiling and testing iOS apps.
So if you’re building cross-platform mobile apps, VirtualBox combined with Android x86 and Hackintosh images can provide excellent mobile test environments without buying expensive devices.
Extensive Customization
VirtualBox gives you tons of ways to customize and optimize your virtual machines. You can enable 3D acceleration for graphics tasks, assign processor execution caps, mount shared folders, create SATA hard disks, configure audio, simulate IO lag, clone VMs, and much more.
Advanced users can further customize settings by tweaking the XML VM configuration files directly. With its modular architecture, you can even extend VirtualBox’s capabilities using community-created plugins and SDKs.
This degree of customizability allows power users to optimize VMs extensively for specialized use cases like gaming, mobile testing, product demos, education, etc.
Consumes Few System Resources
Considering its wide feature set, VirtualBox is surprisingly lightweight. It typically consumes significantly less RAM and CPU than solutions like VMware Workstation. The well-optimized codebase also has lower I/O overhead compared to other virtualization platforms.
This allows you to comfortably run multiple VMs simultaneously even on host systems with limited hardware specs. So if you need good virtualization capabilities without dedicated server-grade hardware, VirtualBox can deliver great performance.
conclusion
With its robust features, excellent performance, and user-friendly interface, VirtualBox has become the top choice for many developers, QA professionals, and tech specialists who work with VMs. The open-source model and lack of licensing restrictions further cement its value proposition.
While solutions like VMware Workstation and Parallels Desktop have their relative strengths, VirtualBox more than holds its own on core functionality. And its extensive customizability allows power users to tailor it to their specialized needs.
So if you are looking for reliable, full-featured virtualization without the high costs, VirtualBox is hard to beat. It delivers excellent cross-platform virtualization capabilities and remains totally free.
