Mac on Linux Intel: The Evolution of Virtualization on Apple Silicon

The shift away from Intel processors and towards Apple Silicon has sparked a wave of curiosity among developers, who rely heavily on virtualization for testing and debugging applications in an isolated environment. As Apple's M1 processor marks the beginning of this transition, the story is improving for virtualization of Arm-based operating systems.

One significant development is VMware Fusion, which is currently in public preview. This commercial system supports Windows on Arm for M1 machines, providing developers with a seamless experience for testing and debugging applications. Additionally, Parallels Desktop has also announced support for running x86 operating systems on Arm-based Apple Silicon devices.

However, there are snags to consider. VMware lamented last year that Rosetta 2, the translation layer that enables x86 applications to run on macOS, does not support virtualization. Moreover, the company added that it is not planning to deliver solutions for running x86 operating systems on Apple Silicon due to a lack of business value relative to the engineering effort required.

The M1 chip's limitations when it comes to running x86 virtual machines are attributed to its architecture. While Rosetta 2 works well for many macOS applications, it is not designed to support x86 virtual machines efficiently. This has led some developers to explore alternative solutions, such as UTM (qemu), which enables Windows on Arm to run on M1 Macs.

Despite these challenges, Apple's decision to transition away from Intel processors is a strategic move that could potentially save developers time and increase productivity. The combination of excellent performance and high efficiency – leading to long battery life for those on laptops – makes Apple Silicon devices attractive options.

The high-end Mac Studio, equipped with the M1 Ultra chip, is a prime example of this. With a maximum power consumption of 215W, according to Apple's specs, it is a modest system that packs a punch in terms of performance and efficiency. As developers continue to adapt to this new landscape, it will be interesting to see how virtualization solutions evolve on Apple Silicon.

In conclusion, the move away from Intel processors presents both opportunities and challenges for developers who rely on virtualization. While there are limitations to consider, the benefits of using Apple Silicon devices – such as increased performance and efficiency – make them an attractive option for those looking to streamline their workflow. As the technology continues to evolve, we can expect to see new solutions emerge that address the needs of developers working with Arm-based operating systems.
