Sorry if this is a repeat but a colleague of mine is taking a full stack frontend masters course: https://frontendmasters.com/learn/fullstack/ And in the first lesson the instructor uses and suggests Multipass:
My colleague says “It is a beautiful product, it is working very well on M1. It’s one of the best virtualisers I have worked with”
The tutor also talks about it in their github.io pages: https://btholt.github.io/complete-intro-to-linux-and-the-cli/lets-run-linux
Thought I’d share the love, good job folks 
much appreciated
