Option 1 - Automatically

zsh -c "$(curl -fsSL https://raw.githubusercontent.com/nrjdalal/silicon-virtualizer/master/install-qemu.sh)"

Option 2 - Manually

• Install Xcode command line tools

xcode-select --install

• Install Homebrew arm64

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/$(logname)/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

• Install necessary packages for building

brew install libffi gettext glib pkg-config autoconf automake pixman ninja

• Clone qemu

git clone https://github.com/qemu/qemu

• Change directory to qemu repository

cd qemu

• Checkout to commit dated June 03, 2021 v6.0.0

• Building qemu installer

mkdir build && cd build
../configure --target-list=aarch64-softmmu
make -j8

• Install qemu

sudo make install

Create Ubuntu Server using QEMU on Silicon based Apple Macs

First run, close manually after installation aka first reboot.

curl https://cdimage.ubuntu.com/releases/20.04/release/ubuntu-20.04.4-live-server-arm64.iso -o ubuntu-lts.iso

qemu-img create -f qcow2 virtual-disk.qcow2 8G

cp $(dirname $(which qemu-img))/../share/qemu/edk2-aarch64-code.fd .

dd if=/dev/zero conv=sync bs=1m count=64 of=ovmf_vars.fd

qemu-system-aarch64 \
  -machine virt,accel=hvf,highmem=off \
  -cpu cortex-a72 -smp 4 -m 4G \
  -device virtio-gpu-pci \
  -device virtio-keyboard-pci \
  -drive "format=raw,file=edk2-aarch64-code.fd,if=pflash,readonly=on" \
  -drive "format=raw,file=ovmf_vars.fd,if=pflash" \
  -drive "format=qcow2,file=virtual-disk.qcow2" \
  -cdrom ubuntu-lts.iso

Second run, enjoy your Ubuntu Server.

qemu-system-aarch64 \
  -machine virt,accel=hvf,highmem=off \
  -cpu cortex-a72 -smp 4 -m 4G \
  -device virtio-gpu-pci \
  -device virtio-keyboard-pci \
  -drive "format=raw,file=edk2-aarch64-code.fd,if=pflash,readonly=on" \
  -drive "format=raw,file=ovmf_vars.fd,if=pflash" \
  -drive "format=qcow2,file=virtual-disk.qcow2"

Bonus, connect via SSH and serve port 80 at localhost.

1. Start server using -

qemu-system-aarch64 \
  -machine virt,accel=hvf,highmem=off \
  -cpu cortex-a72 -smp 4 -m 4G \
  -device virtio-gpu-pci \
  -device virtio-keyboard-pci \
  -drive "format=raw,file=edk2-aarch64-code.fd,if=pflash,readonly=on" \
  -drive "format=raw,file=ovmf_vars.fd,if=pflash" \
  -drive "format=qcow2,file=virtual-disk.qcow2" \
  -nic hostfwd=tcp:127.0.0.1:9922-0.0.0.0:22,hostfwd=tcp:127.0.0.1:9980-0.0.0.0:80 &

2. Login via SSH using -

ssh <username>@127.0.0.1 -p 9922

3. Visit http content at -

open http://127.0.0.1:9980

@KPhans the version installed via brew works great out of the box now. Here's a wrapper script I use, which helps get the qemu command line args right:

Thanks @ericcurtin ! How exactly do I use this script?

Like so... Create a qcow2 file as a virtual hard disk:

qemu-img create fedora_silverblue.qcow2 512G

Run a vm with an installer .iso file to install your linux vm:

runvm --memory 4G --cdrom Fedora-Silverblue-ostree-aarch64-36-1.5.iso fedora_silverblue.qcow2

On every proceeding run:

runvm --memory 4G fedora_silverblue.qcow2

since you guys are using bash/zsh, you can always use array to have a better syntax

#!/bin/bash
#~/bin/qemu_ubuntu

options=(
# this is a comment
# enable hvf for the best performance
-machine virt,accel=hvf
# use a newer cpu, you can also use 'host' with qemu 7.0
#-cpu host
-cpu cortex-a72
# let's do 4core and 4GB RAM
-smp 4 -m 4G
# add a cd rom for the first time boot
-cdrom ubuntu-lts.iso
# let's go on, add anything you want
)
qemu-system-aarch64 "${options[@]}"

now move to your terminal and run

qemu_ubuntu
