+## Host
+
+At the moment hosts with non-x86_64 CPU (like Apple Silicon) are not supported.
+The required full CPU emulation for virtual machine introduces
+too much overhead, making the system too slow and unusable.

 ## Prepare VM
 
 For the deployment we will need Virtual Machine with following minimal requirements.

+### Example command to create an appropriate kvm VM on Linux with `virt-manager`
+
+Needs `virt-manager`, `libvirt`, and `qemu-kvm` installed.
+
+Change the path to the public SSH key as you need, the user in the image is
+`ubuntu`.
+
+```bash
+wget https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64.img
+qemu-img create -F qcow2 -f qcow2 -b jammy-server-cloudimg-amd64.img rockoon.qcow2 100G

+Once the VM is running, run `virsh domifaddr rockoon` to find the IP address
+of the VM to SSH to.

+As mentioned, only Intel-based Macs are currently supported.
