Installing Arch Linux ARM in a UTM virtual machine

Steps:

1. Create a new virtual machine.
2. Go to System tab, change architecture to `ARM64 (aarch64)' and increase memory as needed.
3. Download Alpine Linux LiveCD:

mirror=https://dl-cdn.alpinelinux.org/alpine
curl -o alpine-virt-latest-aarch64.iso "$mirror/latest-stable/releases/aarch64/$(curl "$mirror/latest-stable/releases/aarch64/latest-releases.yaml" | /usr/bin/grep -E 'file: alpine-virt-[0-9\.]+-aarch64\.iso' | head -n 1 | sed 's/ //g' | sed 's/\t//g' | sed 's/^file://')"

4. Go to Drives tab, New Drive, set size to 20GiB or larger, then Inport Drive, choose the file you just downloaded.
5. Go to Display tab, change Type to Console Only to enable pasting.
6. Save the settings.
7. Start the VM.
8. Login as root.
9. setup-alpine

Leave all fileds empty (including password) until selecting a mirror. You might want to use a mirror, and then select `none' for ssh server and everything left.

10. Paste these commands:

alpineMirror=ALPIN_MIRROR
archlinuxARMMirror=ARCH_ARM_MIRROR
hostname=YOUR_HOSTNAME
username=YOUR_USER_NAME

echo "$alpineMirror"'/edge/main
'"$alpineMirror"'/edge/community' >/etc/apk/repositories

11. chroot /mnt /bin/passwd "$username" to change your passwd.
12. poweroff
13. Open VM settings panel, switch to Display tab, change display type back to full graphics and chang scaling algorithm to nearst neighbor.
14. Go to Drivers and remove Alpine Linux LiveCD.
15. Save config, power on and install a graphic user interface.

Hi, i can't connect to network, can you help me ?

how can you create vm without image? how did you skip this process??? like really, first step from you own instructions!

Download Alpine Linux LiveCD:
mirror=https://dl-cdn.alpinelinux.org/alpine
curl -o alpine-virt-latest-aarch64.iso "$mirror/latest-stable/releases/aarch64/$(curl "$mirror/latest-stable/releases/aarch64/latest-releases.yaml" | /usr/bin/grep -E 'file: alpine-virt-[0-9\.]+-aarch64\.iso' | head -n 1 | sed 's/ //g' | sed 's/\t//g' | sed 's/^file://')"

that image?

This is Alpine Linux. Not Arch Linux actually. So please replace the title because it doesn't talk about Arch Linux (yeah i could do that with Debian too 😒)

Evidently, you aren't familiar with Arch Linux. Since there is no Aarch64 boot iso for Arch Linux, these instructions get you started with a bootable Alpine Linux image, essentially as a rescue disk, but from there you configure pacman and use pacstrap to install the Arch "base" and "linux" parts of Arch to the virtual disk, you are literally installing Arch. Once you eject the Alpine rescue image and boot from the disk image, you're running Arch. Please delete your confusing and misguided comment.

Not exactly because it stays Alpine, Arch has AL-ARM which is a port of it who has a boot iso for aarch64. So please rectify the use of alpine.

Hi, I'm stuck at points 8 and 9.

I've downloaded the Alpine Standard ISO, set up a new VM in UTM (actually Emulation for x86 image) and booted. It runs its startup.nsh and then places me at a Shell> prompt.

I'm not able to find any files/folders on any of the FS0 or BLK* mounts except the efi/boot directory, so no setup-alpine script. There's also no su command available, so I don't know how to login as root.

Any hints would be much appreciated.

I've used archboot, and it installs pretty straight forward. But when I'm in plasma, I couldn't see the fonts properly. To fix it, I had to change the M1 resolution to 1800x1169 and inside plasma, change it as well to 1920x1080.

👎 Really a bad option. Guys if you want Arch Linux on ARM go install the true ALARM from the website. This is a fake Arch (a disguised Alpine actually.).
