Installing and running ubuntu on arm64/virt machine (Guest has not initialized the display (yet).")

[ckim]

Hi, list members,

 

While investigating how I can install ubuntu on a qemu virtual machine, I found https://askubuntu.com/questions/884534/how-to-run-ubuntu-desktop-on-qemu .

So I found how to install the OS onto a hard disk using CDROM, and then boot from the OS installed hard disk as in real computer. Very interesting.

And I tried ubuntu 18.04.5 on arm64/virt machine (I used the original virt machine).

The script is below (modified for my case). (configured with –enable-gtk option)

 

#!/usr/bin/env bash

 

set -eux

 

# Parameters.

id=ubuntu-20.04.2-live-server-arm64

disk_img="${id}.img.qcow2"

disk_img_snapshot="${id}.snapshot.qcow2"

iso="${id}.iso"

 

# Get image.

if [ ! -f "$iso" ]; then

  wget "http://releases.ubuntu.com/20.04/${iso}"

fi

 

# Go through installer manually.

if [ ! -f "$disk_img" ]; then

  qemu-img create -f qcow2 "$disk_img" 1T

  ../QEMU/qemu-5.1.0/build/aarch64-softmmu/qemu-system-aarch64 \

    -M virt -cpu cortex-a72 \

    -cdrom "$iso" \

    -drive "file=${disk_img},format=qcow2" \

    -m 2G \

    -smp 2 \

  ;

fi

 

# Create an image based on the original post-installation image

# so as to keep a pristine post-install image.

if [ ! -f "$disk_img_snapshot" ]; then

  qemu-img \

    create \

    -b "$disk_img" \

    -f qcow2 \

    "$disk_img_snapshot" \

  ;

fi

 

# Run the copy of the installed image.

../QEMU/qemu-5.1.0/build/aarch64-softmmu/qemu-system-aarch64 \

  -M virt -cpu cortex-a72 \

  -drive "file=${disk_img_snapshot},format=qcow2" \

  -m 2G \

  -smp 2 \

  -device intel-hda -device hda-duplex \

  -device virtio-gpu-pci \

  "$@" \

;

I separately downloaded ubuntu-20.04.2-live-server-arm64.iso from https://ubuntu.com/download/server/arm so the first wget command is not executed.

When I first run the script, I see a qemu monitor window. And I type ‘quit’, and then another window comes up saying “Guest has not initialized the display (yet).”

What is wrong with this script? Any advice will be very much appreciated.

Thanks!
