ARM64 Linux on Win10

arm64-on-Win10.md

Below are the steps to get an ARM64 version of Ubuntu running in the QEMU emulator on Windows 10.

Install QEMU

Install for Windows from https://qemu.weilnetz.de/w64/ (I used qemu-w64-setup-20181211.exe)

Put C:\Program Files\qemu on your PATH, and run the below to check it's working (which will list out the CPUs the AArch64 emulator can emulate):

qemu-system-aarch64 -M virt -cpu help

Copy the Firmware and OS images

Into your working directory...

• Copy the ubuntu-16.04-server-cloudimg-arm64-uefi1.img OS image from https://cloud-images.ubuntu.com/releases/16.04/release/
• Copy the QEMU_EFI.fd firmware image from https://releases.linaro.org/components/kernel/uefi-linaro/latest/release/qemu64/

Create the configuration data image

The Ubuntu server images require configuration data be provided as an image, such as setting auth credentials.

The tool used to convert the config text file into an image file only runs on Linux, so I've attached a user-data.img file (and the text file used to create it) in a zip file to this Gist. Extract the user-data.img file to the working directory.

The user-data.img file was created for password authentication as outlined in https://stackoverflow.com/a/53373376

Launch the emulator from the working directory

Run the below to boot the image, you will some some benign errors at startup. Wait until the output settles down (even after you see the login prompt, as the post-boot config may not have completed yet).

qemu-system-aarch64 -m 2048 -cpu cortex-a72 -smp 4 -M virt -nographic -bios QEMU_EFI.fd -drive if=none,file=ubuntu-16.04-server-cloudimg-arm64-uefi1.img,id=hd0 -device virtio-blk-device,drive=hd0 -drive file=user-data.img,format=raw -device virtio-net-device,netdev=net0 -netdev user,hostfwd=tcp:127.0.0.1:2222-:22,id=net0

To break down these lines:

• qemu-system-aarch64 -m 2048 -cpu cortex-a72 -smp 4 -M virt -nographic - run the ARM64 virtual platform emulator with 2GB RAM and 4 Cortex-A72 cores with no GUI support.
• -bios QEMU_EFI.fd - use the firmware downloaded above.
• -drive if=none,file=ubuntu-16.04-server-cloudimg-arm64-uefi1.img,id=hd0 - use the Ubuntu image file
• -device virtio-blk-device,drive=hd0 - mount drive from above as a block device
• -drive file=user-data.img,format=raw - use the configuration data image file
• -device virtio-net-device,netdev=net0 - create a virtual network device
• -netdev user,hostfwd=tcp:127.0.0.1:2222-:22,id=net0 - set up the networking stack and forward the SSH port

Then from a good Terminal emulator (I recommend the new Windows Terminal app with one of the Powerline fonts) you can connect over SSH with the below, and the configured password (asdfqwer):

ssh ubuntu@localhost -p 2222

I tested this in Windows 11 and using ubuntu-22.04-server-cloudimg-arm64.img it works. All the rest remains as-is. I owe you a beer, thank you.

Expanding the image size by 8GB

shutdown the vm qemu-img resize ubuntu-16.04-server-cloudimg-arm64-uefi1.img +8G start the vm, ssh into it and enter the following command sudo growpart /dev/vda 1 reboot

Works in ubuntu-22.04-server-cloudimg-arm64.img right away without any subsequent growpart anymore. Thank you.

hello, thank you very much.
I successfully installed above environment. But now I need to increase disk size of image. how can I find above image file on my Ubuntu and how to increase the disk size?

Works well on Windows 11, just had to wait some time to load cloud-init (wasn't able to login with those credentials)

It works, entered the system without problems

works like a charm for ubuntu-22.04-server-cloudimg-arm64.img
only difference made - allow others host systems to connect via ssh by changing hostfwd=tcp::2222-:22
