Indeed, I was going to point out the lack for KVM as well. The same is also very true when it comes to Linux networking stuff. One of the most difficult things I've ever had to do was complicated networking stuff with KVM/qemu VMs when I had nobody to ask or talk to about it. There are enormous swaths of undocumented surface (or lightly documented by a blog post that may or may not be accurate anymore, and is nowhere near comprehensive). One of my biggest hope for LLMs like GPT-4 is the ability to improve on this, though as of right now it hallucinates like mad. The more niche the case, the worse it gets too.
