Short summary to run Linux VMs on an Apple M1 host using QEMU, libvirt and HVF with a working network setup

Linux Virtual Machines with Private Network on an Apple M1 Device

Background

The aim was to be able to:

  1. Run multiple Linux VMs on an Apple M1/ARM device
  2. Use Apple's HVF for native performance speeds
  3. Configure VMs to allow network access to each other
  4. Configure VMs to allow access to the internet
  5. Not rely on custom modifications of software
