I'm not a virtualization expert, and it's likely some of my comments demonstrate that... You're going to need to update your copyright dates to include 2023 now. I haven't looked at the earlier reviews; perhaps the RFC stuff was requested. I'm sure it's useful to see that but it doesn't seem directly helpful if your goal is to get this code upstream. At this point I've reviewed only through patch 9. I currently have smallish blocks of time and I don't want to hold back my feedback for too long. -Alex > Changes in v8: > - Treat VM manager as a library of RM > - Add patches 21-28 as RFC to support
