Enable the VMM to hijack system calls executed by the guest.
- If enabled, the VMM will intercept software interrupt (INT) instructions,
- Fast-System Call instructions (SYSENTER, SYSCALL), and the LIDT instruction
+ If enabled, the VMM will hook execution of INT 80
+ (support for Fast-System Calls coming soon)

+ If enabled, this option will cause all system calls
+ that are not explicitly hooked to be hooked for
+ passthrough. This is useful for debugging.
