Ask for questions about Xen development
Dear Sir or Madam:

I am a student who is studying analysis of software which run in the guest on Xen. And I want to know if ther is a method to monitor guest's instructions at the level of Xen. In other words, I want modify Xen's source code to obtain the information about guest's state once one instruction is executed. I have known that how to modify Xen's source code to monitor system calls that occur in guest, but I don't know if it is feasible to monitor common instructions which is neither Privileged instruction nor Sensitive instruction.




Thanks for your reading. Look forward to your early reply.

Hello,

Thank for your interest in Xen. I am adding Tamas and Razvan. They are both
looking at VM introspection and should be able to help here.

Best regards,
