But, I think the most important part is to make the data accessible somehow. So, the monitor access method would work fine as well.

I don't object to read/write access.

If there's read and write access, it needs to be part of the savevm state. Is it per-cpu? If it's write only, then it doesn't need to be persisted in savevm.

I'd lean toward write-only unless there was a compelling reason to make it read/write.

Well it was write-only before, so I don't see any harm in keeping it that way. Or am I mistaken there?
