Agreed, it's hard to find consise and useful docs on this. The best I've 
found was this: 
https://habkost.net/posts/2016/11/incomplete-list-of-qemu-apis.html but 
not sure how relevant is it still. Maybe should be more prominently linked 
or put on the wiki.

Also renaming init to alloc might help to clear some confusion. (Alloc and 
realize are still a bit confusing but less so than also renaming realize 
to init.)
