Emulation

I have been using Parallels for a couple of years now, primarily for running Windows virtual machines (VMs), but occasionally Linux VMs too. I mostly use it for playing games, testing, and the occasional Windows-only application. There are some other long-standing options such as VirtualBox, QEMU, and VMWare. I am intentionally ignoring anything that also runs containers, such as Docker, as that’s a different use case, and a whole other gamut of options.

I've been happily using [Parallels Desktop][1] for my Windows and Linux virtual machine needs for about the past three years. It's performant, supports a reasonable variety of guest operating systems, and, with some tweaks, can also run headless developer machines and Kubernetes clusters.

Changes in recent versions of macOS have made running macOS and Linux virtual machines far easier and more performant. Primarily used for testing, a plethora of new applications that take advantage of these features emerged, so when Mac Stadium released a free desktop version of their long-running Okra range of virtualisation tools, one feature in particular stood out to me as something different and potentially useful.
