How to set up QEMU working properly on M1 Mac

Last-Update: June 8, 2021.

This document describes how to run Windows 10 for ARM and Linux operating systems properly on Apple Silicon (M1) Mac by using open source software only. The combination of [QEMU] and [Alexander Graf's Hypervisor.framework support patch][Alexander Graf's patch] allows us to run Windows 10 and Linux for 64-bit ARM processors on M1 Mac efficiently. Several webpages such as [How to run Windows 10 on ARM or Ubuntu for ARM64 in QEMU on Apple Silicon Mac] and [QEMU on M1 Mac] describe how to set up a QEMU environment with Alex's patch. While they are helpful for the first trial, additional effort is needed to realize a proper QEMU environment that can be used for our daily business.

1.0 Introduction to btrfs

Btrfs: “ZFS lite” for Linux
Oracle’s Btrfs filesystem project (“B-tree file system,” officially pronounced “butter FS” or “better FS,” though it’s hard not to think “butter face”) aimed to repeat many of ZFS’s advances on the Linux platform during the long interregnum when ZFS seemed like it might be lost to Linux because of licensing issues.
BtrFS VS ZFS
