[vbox-dev] SysyemCall in VirtualBOx

[Francesco Di Paolo]

hello there,
i'd like to have some informations in regards to how the hypervisor takes over when a system call(int 0x80) occurs in the
 guest OS. How it is managed the passage from Ring3 to Ring1. What i'm facing is understand what is going on when an application in the guest OS invokes a system call(i didn't get if it is involved the host kernel and its IDT or if there are interactions only between the application and the guest kernel). If you 
could give us some suggestions, we would be very grateful.
