[Xen-devel] question about system call mechanism in xen

["Zang Hongyong" <zanghongyong@xxxxxxxxxx>]

hi,
  I'm interested in system call mechanism in Xen. My understanding (guess) as 
follows.
   1)When user application makes a system call, a "int 80" will occur. 
   2)Then trap to Ring 0 (Which is hypervisor's location). 
   3)Then hypervisor redirect it to Guest OS's kernel to do system call 
operation.
   4)Then back to Ring 0
   5)back to user appliction

  Is that true?
  Where can I get documents about this question in detail?

thanks in advance
