This was an interesting discussion. I must be missing something though: - page mapping visibility: several people said that they felt uncomfortable with the global visibility of mappings from machine to physical address in a guest as this provides a lot of information to an attacker. How does letting an attacker know the physical to machine mappings benefit an attacker? I assume the attacker still would not have read/write access to pages that do not belong to the compromised domain. Is there a concrete attack that people are aware of, or is this just a precautionary measure?
