Guest OS
 
I have the following question. Please let me know if you know anything about it.

Q- Suppose a guest OS G is running on top of Linux OS. The underlying hardware is based on intel IA-32 hardware. An application program from G makes a system call which results in a trap which will give control to the host OS. Now the main part of the question is that how can we virtualize system calls issued by G so that they are serviced by the kernel code of G. How would you differentiate and control the the application and kernel stacks in G?

Thank you!

Since you're talking about guest OSs, I pressume you're asking about VMWare? Or something else like UML?
