For the minor machines (that is: not the ones which have version number suffixes like pc or virt) we do not make a record of changes. Generally any changes will be either bug fixes to the model, or occasionally implementation of new features. Akita in particular is not really very actively maintained, so I don't think it's had any significant changes. If you have a guest that used to boot and no longer does: (1) First check whether your guest boots on a modern QEMU (ie the most recent release, which is 6.0) (2) If it doesn't boot on 6.0, do a git bisect to try to find the commit where your guest stopped working. That should help in identifying what the problem is. thanks -- PMM
