Few build Hypervisors. We're one of them (virtualize.sh)
Everyone uses virtualization. Few truly understand what they’re building on. That’s why calling hypervisors a commodity is a dangerous illusion.

Setup QEMU Output to Serial Console and Automate Tests with Shell Scripts (2019) (fadeevab.com)
While struggling to automate QEMU guest (communicate and control with the shell scripts), I faced a lot of incomplete, partially working solutions around the Internet. Now, I've got a pretty decent collection of working recipes to tune up a QEMU guest, so I decided to organize all that stuff here, and it could be definitely useful for anyone else.
