Vagrant and VMWare Tech Preview 21H1 on Apple M1 Pro

UPDATE November 20, 2022: VMWare Fusion 13

VMWare Fusion 13 is now released. Read Vagrant and VMWare Fusion 13 Player on Apple M1 Pro for the latest.

Summary

This document summarizes notes taken while to make the VMWare Tech preview work on Apple M1 Pro, it originated

Guide: Run FreeBSD 13.1-RELEASE for ARM64 in QEMU on Apple Silicon Mac (MacBook Pro M1, etc) with HVF acceleration (Hypervisor.framework)

This guide was adapted from https://gist.github.com/niw/e4313b9c14e968764a52375da41b4278#running-ubuntu-server-for-arm64

Running FreeBSD 13.1-RELEASE for ARM64

Install Xcode from App Store or install Command Line Tools on your Mac running on Apple Silicon.

Key Points

In general, binaries built just for x86 architecture will automatically be run in x86 mode
You can force apps in Rosetta 2 / x86 mode by right-clicking app, click Get Info, check "Open using Rosetta"
You can force command-line apps by prefixing with arch -x86_64, for example arch -x86_64 go
Running a shell in this mode means you don't have to prefix commands: arch -x86_64 zsh then go or whatever
Don't just immediately install Homebrew as usual. It should most likely be installed in x86 mode.

Homebrew

Not all toolchains and libraries properly support M1 arm64 chips just yet. Although

Docker on Android 🐋📱

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.

Summary

What to Expect and Tips

• 45-minute systems interview, focus on responding to real world problems with an unhealthy service, such as a web server or database. The interview will start off at a high level troubleshooting a likely scenario, dig deeper to find the cause and some possible solutions for it. The goal is to probe your knowledge of systems at scale and under load, so keep in mind the challenges of the Facebook environment.
• Focus on things such as tooling, memory management and unix process lifecycle.

Systems

More specifically, linux troubleshooting and debugging. Understanding things like memory, io, cpu, shell, memory etc. would be pretty helpful. Knowing how to actually write a unix shell would also be a good idea. What tools might you use to debug something? On another note, this interview will likely push your boundaries of what you know (and how to implement it).

Design/Architecture

Interview is all about taking an ambiguous question of how you might build a system and letting

	# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
	# Initialization code that may require console input (password prompts, [y/n]
	# confirmations, etc.) must go above this block; everything else may go below.
	if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
	source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
	fi

	# If you come from bash you might have to change your $PATH.
	export PATH=$HOME/bin:/usr/local/bin:$PATH

	# Namespace / Service
	- A pod can access a service in its own namespace by just using service name.
	A pod can access a service in a different namespace by using below format.
	<svc-name>.<ns-name>.<svc>.<cluster.local>
	e.g db-service.dev.svc.cluster.local
	- When a service is created, a DNS entry is added automatically in this format:
	db-service.dev.svc.cluster.local
	Here db-service is service name, dev is namespace, svc represents service and cluster.local is domain.
