i've already posted a similar question some months ago...but nobody gave me an answer. So i'm trying again. It's just a yes or no question:in order to maintain  consistency between shadow PT and guest PT, we have to write-protect the guest PTs(the memory tracing technique). Is it right that,in order to protect them, we set the Write Protection bit of CR0 in the guest OS?
