With the recent launch of several low cost Cortex A53 development boards, 64-bit ARM hardware is now pretty common and inexpensive, but if you want to run 64-bit ARM code on your x86 Linux computer, Riku Voipio, a software engineer working for Linaro, wrote some instructions to run Ubuntu 16.04 Aarch64 Cloud image in QEMU. Ubuntu cloud images are “the official Ubuntu images and are pre-installed disk images that have been customized by Ubuntu engineering to run on public clouds that provide Ubuntu Certified Images, Openstack, LXD, and more. ” So the instructions are also useful if you want to easily try such packages on 64-bit ARM platform.
I’ve tried those instructions myself on my Ubuntu 14.04 machine with and AMD FX8350 processor, and they worked pretty well, and the only things I had to find out by myself was to install a recent version of qemu.
First, we’ll need to install qemu & cloud-utils, and download QEMU EFI firmware as well as the Ubuntu 16.04 Xenial server Cloud image:
|
1 2 3 |
sudo apt install -y qemu qemu-utils cloud-utils wget https://releases.linaro.org/components/kernel/uefi-linaro/15.12/release/qemu64/QEMU_EFI.fd wget https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-arm64-uefi1.img |
The instructions require qemu-system-aarch64 version 2.5, and my system only comes with qemu 2.0.0
|
1 2 |
qemu-system-x86_64 --version QEMU emulator version 2.0.0 (Debian 2.0.0+dfsg-2ubuntu1.22), Copyright (c) 2003-2008 Fabrice Bellard |
So I had to find a qemu ppa to install a more recent version:
|
1 2 3 |
sudo sudo apt-add-repository ppa:gns3/qemu sudo apt update sudo apt install qemu-system-aarch64 |
I now have version 2.5:
|
1 2 |
qemu-system-aarch64 --version QEMU emulator version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu1), Copyright (c) 2003-2008 Fabrice Bellard |
Since the Cloud images don’t come with default username and password, they need to configured with cloud-utils. To do so, I created cloud-utils as follows:
|
1 2 3 4 5 6 7 8 9 |
#cloud-config users: - name: <your_username> ssh-authorized-keys: - ssh-rsa AAAAB3NzaC1y.... sudo: ['ALL=(ALL) NOPASSWD:ALL'] groups: sudo shell: /bin/bash |
You simply need to change the file with your username, and RSA key, which should be in ~/.ssh/id_rsa.pub. If you don’t have that file you may want to read my post showing how to create the SSH key and login without password. Cloud config can take many arguments, including packages to install during the first boot, and you can learn all about it on Cloud-init documentation.
Now you can initialize the cloud image, and run it:
|
1 2 3 4 5 6 7 8 |
cloud-localds cloud.img cloud.txt qemu-system-aarch64 -smp 2 -m 1024 -M virt -bios QEMU_EFI.fd -nographic \ -device virtio-blk-device,drive=image \ -drive if=none,id=image,file=xenial-server-cloudimg-arm64-uefi1.img \ -device virtio-blk-device,drive=cloud \ -drive if=none,id=cloud,file=cloud.img \ -netdev user,id=user0 -device virtio-net-device,netdev=user0 -redir tcp:2222::22 \ -cpu cortex-a57 |
The boot until the login prompt tool about 3 minutes on my machine. Here’s the boot log:

Emulation from x86 to ARM is affecting the results quite a bit here. For reference, a Raspberry Pi 2 achieves about 113300 KFLOPS for the same benchmark. You’ll also noticed specifically compiling for Cortex-A57 CPU improves the performance by about 10%, even in qemu.

Thanks a lot for writing this up. I’m struggling to get this working, and have tried a few formulas including yours.
xenial-server-cloudimg-arm64-uefi1.img boots up, but cloud-init fails during the boot process. My cloud.txt file — the 2nd argument to cloud-localds — is yours verbatim with my username and ssh key filled in. I get this on the console during boot:

Trying to ssh to port 2222 on localhost returns with:
Connection closed by 127.0.0.1 port 2222
So, I gather that /var/lib/cloud/instance is not a directory, i.e., probably doesn’t exist? Have you seen such a thing before, and any suggestions?
Thanks.
@Luddy Harrison
I have not been playing with the image much, and I’m not sure what your exact issue may be. I don’t have /var/lib/cloud inside my host system (Ubuntu 14.04), so that’s probably within the cloud image itself. I can see the update the image daily, so a bug may have been introduced in the image.
My log only read at the stage of your error.

@cnxsoft
And your bug is actually listed @ https://bugs.launchpad.net/cloud-init/+bug/1577753
@cnxsoft
Thanks! I pulled a fresh image, and now everything works as expected.
Thank you for the great post! I followed all your steps and I also have a Ubuntu 14.04 with AMD64 CPU. However, in the last phase of ssh to the 2222 port of the local host, I always get the error message of “Permission denied (publickey)”. I can ssh to my localhost without typing any passwords. Just the port 2222 always fails on me. Any suggestions? Thanks!
@Peter Cooper
Double check your key @ ssh-authorized-keys: – ssh-rsa AAAAB3NzaC1y….
@cnxsoft
Here is the content of my id_rsa.pub:
This is the content of my cloud.txt:
And this is the content of my authorized_keys:
I can directly login to my localhost without typing keys but I cannot do it the same to port 2222. Not sure what is wrong here…
@cnxsoft
Is there any way to know the username and password of the cloud image so that we could login directly from that console?
@Peter Cooper
I can see admin@admin is missing from the key in cloud-config. Maybe that’s the reason.
I don’t think there’s a default username/password for the cloud image, everything is defined in cloud-config.
@cnxsoft
I added admin@admin in cloud.txt and re-started the VM. But I still cannot login… I also tried to change authorized_keys in ~/.ssh/ to authorized_keys2, again, no luck…
This is a great write-up. It is recent, concise and clear. Most of all, it is a lifesaver for me. Just one update, with ubuntu 16.04.01, one can directly install qemu-system-aarch64 2.5, sudo apt-get install qemu-system-arm.
@Peter Cooper
The instructions have left out the installation of cloud-init! It is not included in cloud-utils.
Without it, the line:
cloud-localds cloud.img cloud.txt
does nothing without a peep.
@Jun Sun
Is it possible to use an existing Cortex-A53 image after replacing the kernel, etc?
Everything works except the login via ssh. I’m pretty sure all is done as it must be done. Perhaps one question: the public key needs to be copied with or without the email address? (or login address whatever it is)
thanks
@agguro
I think it has to be the full content of ~/.ssh/id_rsa.pub
I did it but nothing:

Are you sure you want to continue connecting (yes/no)? yes

Anyone an idea?
also, isn’t it better to add a user exp admin pwd admin as sudo in the image file? the ssh option doesn’t seems to work here
@agguro
It looks like you have the exact same problem as Peter @ http://www.cnx-software.com/2016/05/10/how-to-run-ubuntu-16-04-aarch64-64-bit-arm-cloud-images-on-your-intelamd-linux-computer/#comment-531159
Maybe something changed since I posted the instructions.
@agguro
It might be possible to do that. You’d have to check cloud-init documentation.
I also can not pass ssh key via this config file, so I just added new user to ubuntu and logged with it.
Steps for people who forget old ways to change password:
1. In grub go to recovery mode and in the end of line root=… add
init=/bin/bash
then you will boot up with root console.
2. mount -o remount,rw /
3. adduser myuser
4. add user to /etc/sudoers
5. sync
6. reboot or kill qemu and boot again.
srry guys, maybe I’m stupid or so but I can edit the grub menu and boot in recovery mode but the system keeps asking for a password. I wonder if an installation can be done from an iso file, just like an emulated cdrom like I did for qemy-system-arm
check that you provided init=/bin/bash on right line.
sorry, nothing seems to work

please help
@aaguro , @cnxsoft Any luck on ssh ? I am still not able to ssh with the keypair setup . I tried as mentioned by aaguro.
thanks

@Chethan
Did you use the whole string with user@ubuntu or whatever you might have at the end?
So to say like this:
users:
– name: username
ssh-authorized-keys:
– ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDWSfN+SKdja1sxKYwcodrzu+04kgbUwFx7m5gKHc7M9kVO6qymK/Bo9qxpHrRdUICcDqLHbKEE7Buos0frsncemRP0OVBD1m0UlJ6v5mr90lUpiK4tJ551Z2a0Fan2FHSPg5M3DgKW7HugPyiz2cX67PZc0tGqoMRnjeiW6MUDTqE2wuLPgxNm9z8MHCWPsH7W4RuQosCbtjn5164bpRSpf39br9dFgAiUfufFvLjDZR+AUlbenVt1UR3oiAi46alW0ZJxfCrOPqfuUmsOHTOjI24LLWC6S9E0zB5SMm59zOcJ4xQjsMTja/sZJ215jfXuHRf3BM8tTDye25jibAq9 user@ubuntu
sudo: [‘ALL=(ALL) NOPASSWD:ALL’]
groups: sudo
shell: /bin/bash
Also when generating the ssh key with “ssh-keygen -t rsa -f .ssh/id_rsa” don’t use it with sudo, for me it placed it in the root files which didn’t work.
You might also try to add a password so you can access ubuntu without ssh if you dont require it particularly. So for me it looked kinda like this in the end:
users:
– name: username
plain_text_passwd: ‘mypassword’
homedir: /home/username
lock_passwd: false
ssh-authorized-keys:
– ssh-rsa …
sudo: [‘ALL=(ALL) NOPASSWD:ALL’]
groups: sudo
shell: /bin/bash
most of the information for the cloud-init is given here, just try to tinker around a bit: https://cloudinit.readthedocs.io/en/latest/index.html
And don’t forget to rebuild the cloud img when you change smth.
https://gist.github.com/george-hawkins/16ee37063213f348a17717a7007d2c79
here is another link with a few more tips based on this tutorial which might help you
@Knoedel
@Chethan
Another thing to add I always reset the Ubuntu image when I rebuild the cloud image so I have the original one from the download.
Sorry this is wrong, it created a keypair in the specified folder as root@ubuntu user instead of user@ubuntu so you have like ssh-rsa AAAAB3N … root@ubuntu. I guess it works like this but then you have to use sudo when calling “ssh -p 2222 username@localhost” and also place the rsa key into the “/root/.ssh/” directory instead of the “~/.ssh/”.
So the easiest way is not using sudo when calling “ssh-keygen -t rsa -f ~/.ssh/id_rsa” and “ssh -p 2222 username@localhost”.
@Knoedel
Thanks a lot for helping out here. It finally worked after trying out the user@ubuntu and rebuilding the cloud image.
