I know the difficulty to attack on memory deduplication. I think the situation is same as Corss-VM Side Channel Attack [CCS'09] and Cold Boot Attack [USENIX Security'08]. However, from the view of security, we have to know the vulnerability. The practical evaluation should based on the balance of possibility and impact. I agree the possibility is low and there is no practical attack on current situation. ------ Kuniyasu Suzaki -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
