Root cause of this issue: nobody knows how to use QOM correctly (first order approximation). In particular, people are perenially confused on how to split work between .instance_init() and .realize(). We really, really, really need to provide some guidance there! Right now, all we provide are hundreds of examples, many of them bad.
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.)
