I usually use QEMU for Android, so I don’t have any tutorials I could recommend, at most having their docs at hand.

Also no Android tutorial either as I go by muscle memory on Android due setup changing between Android distros, their versions, and versions of QEMU, and me using Android offline so always the same installer.

But as apparently QEMU is one of the better VM tools around, there should be plenty of tutorials too. If you go for major distros, with their hardware compatibility being more or less the same afaik, QEMU setup tutorials should be overarching too.

And if the tutorials you find don’t fully or properly cover your chosen distro, since you seem to be willing to tinker, you could do like I did with Android and pick some random tutorial as a start point and figure out what changes from there.
