""" The goal of this project is to enable MacOS users to:
Easily spin up and manage lightweight Alpine Linux environments. Use tiny VMs to take advantage of containerisation technologies, including LXD and Docker. Build and test software on x86_64 and aarch64 systems """
I experimented with LXD containers on Linux recently, but I found the technology it builds on (cgroups) too hard to wrap my head around, and tutorials leave me in the dark. E.g. here is page 2 of one tutorial: https://access.redhat.com/documentation/en-us/red_hat_enterp... All these rules made no sense to me, and while I suppose they become clear at some point, I like my tutorials to be clear from the start.

That said I don't remember having to learn all that much about cgroups when I last looked at lxc...

QEMU can use the MacOS virtualization framework layer to run a VM built for the same arch without going through any translation. From there you can register Rosetta as a runtime and use it to run x86-64 Linux apps on ARM64 if you want. ( https://developer.apple.com/documentation/virtualization/run... )

Wait, what? QEMU can pass x86 instructions directly to Rosetta without emulating an entire host OS?

This is good news. I come from the development background and the number one use case of containers on macOS is development enviroments, as on Windows too. For this use case, file system IO has always been bottleneck, not CPU. I do not know if there is some silver bullet in the horizon that could make this faster.
I've been really impressed with what I can accomplish with lima-vm, beyond just "replace docker desktop". The latest pre-release supports Virtualization.framework, including virtiofs.
Does QEMU emulate the CPU on macOS?
