Hi:
To detect and handle unauthorized memory map from hvm to dom0，I found xsm can prevent a privileged domain from arbitrarily mapping pages from other domains,however,I try to find whether there is another way. So I try to trap the memory access and compare the page owner whth the accessor, if they are different, somthing must happend and a warning to the administrator will be raised.
My question is how can I trap the memory access? Is there any other mechanism to detect unauthorized memory map?With EPT/NPT, memory access are so closed to hardware that I don‘t know how should I trap it?Can you give me any suggestion?
Thank you very much!
Jone
