はじめに

macOS上のParalles上の Linux で、qemuによる VM が動かせるということなのでやってみたメモ
世にいう nested virtualization
Parallesは qmue で動いているそうなので、macOS 上で qemu 上の qemu という感じ

環境

MacbookPro M3 Max 64GB
macOS Sequoia 15.6.1
Parallels Desktop 26 fro Mac Pro Edition 26.1.1
Ubuntu 25.04
alpine standard 3.22.2

前提

Paralles 上に Ubuntu はすでにインストールされているとします。

手順

必要なパッケージをインストール

sudo apt update
sudo apt upgrade -y
sudo apt install qemu-system-aarch64 qemu-utils qemu-efi-aarch64

alpine linuxのダウンロード

使いたいバージョンをダウンロードしてください。大事なのは、aarch64 であること。

wget https://dl-cdn.alpinelinux.org/alpine/v3.22/releases/aarch64/alpine-standard-3.22.2-aarch64.iso

仮想ディスクの作成

qemu-img create -f qcow2 alpine.qcow2 2G

VMの起動（インストール時）

ヘッドレス／シリアル、4コア、I/O最適化、rng 追加、軽めCPU＆GICv2 で起動
