Hi there,

I have a question related to intercepting guest OS system calls in Xen to provide logging mechanism.
As a part of my project, i have to log all the system calls issued by the guest OS in the Xen hypervisor for secure logging. I am new to Xen and have been reading the source code. I have read about Fast Handler for system call. What is the fast handler and how the system call works in Xen. Could you please provide me some starting point how to do that?

Will it be a very difficult to log guest OS system calls in Xen ? If no, how to start with and what are files have to be changed.

I would really appreciate your help.

Thanks,
Neha
