Fedora aarch64 QEMU system image runner script

run-aarch64.sh

#!/bin/bash

# Starter script for Fedora aarch64 in QEMU, cobbled from various sources.
# Requires qemu-system-aarch64 to be installed.

# Configuration options:
IMAGE=fedora-29-aarch64.img
RAM=2048
CPUS=4

# Get a Fedora Minimal or Server aarch64 system image from
# https://alt.fedoraproject.org/alt/
# Decompress with 'xz -d' and put it somewhere handy.
# On first boot, there will be some setup questions before login.

# Note -- must also obtain QEMU_EFI.fd firmware file to boot!
# On Fedora, install qemu and grab it from /usr/share/edk2/aarch64
# or find a snapshot from Linaro etc.

# And now we run:
qemu-system-aarch64 \
    -no-user-config \
    -nodefaults \
    -display none \
    -m ${RAM} \
    -cpu cortex-a57 -machine virt \
    -smp ${CPUS} \
    -bios QEMU_EFI.fd \
    -device virtio-scsi-device,id=scsi \
    -drive file=${IMAGE},format=raw,if=none,id=hd0 -device scsi-hd,drive=hd0 \
    -netdev user,id=usernet -device virtio-net-device,netdev=usernet \
    -boot efi \
    -serial mon:stdio

# Additional notes:
# This bridges the serial console to your terminal, which is handy.
# The 'mon:' in the -serial line fixes ctrl+C so it doesn't kill qemu;
# to close the emulator you must either shut down the VM from inside
# or kill the process.

# Ok that's it. Enjoy!
