How to Run Ubuntu 16.04 Aarch64 (64-bit ARM) Cloud Images on Your Intel/AMD Linux Computer with QEMU
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.
Ubuntu 16.04 with Linux 4.4 Running on a Dual Core Cortex A57 Processor in QEMU
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:

The instructions require qemu-system-aarch64 version 2.5, and my system only comes with qemu 2.0.0

So I had to find a qemu ppa to install a more recent version:

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:

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:

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.
