Umbrel is a small server you can buy to self host your stuff and an operating system you can install on a raspberry pi.
Umbrel OS gets released for two types of architectures, armv8 and amd64. No arm64. So if you have an apple silicon mac you are out of luck running a virtual machine with umbrel OS. But I wanted to have a umbrel VM on my mac to test things.
As it turns out it is quite simple to tell the build system to also build for arm64.
So I have forked umbrel and added arm64 support.

git clone https://github.com/SimonHaas/umbrel
cd umbrel/packages/os
# 1. Build the arm64 OS image (if not already built)
npm run build:arm64
# 2. Prepare (compress) the arm64 image
npm run build:arm64:usb-installer:prepare
# 3. Build the arm64 USB installer ISO
npm run build:arm64:usb-installer
Now you have a umbrel/packages/os/usb-installer/build/umbrelos-arm64-usb-installer.iso which you can use to run a VM on apple silicon with a hypervisor of your liking.
You can download a version I have build here:

Tested with:
Add a disk with at least 30 GB.
- Parallels Desktop
- VirtualBox
- setup port-forwarding for 80:80/tcp (when using default NAT network adapter)
- http://localhost/
- VMware Fusion
- UTM does not work
- Display output not active
- also tried adding a Serial Device
Caveats:
OS-updates do not work (I have not yet looked into how the update mechanism works) and I do not recommend running this version as your ‘production’ home server.
