Virtual machine monitors (VMMs) have enjoyed a resurgence in popularity, since VMMs can help to solve di#cult systems problems like migration, fault tolerance, code sandboxing, intrusion detection, and debugging. Recently, several researchers have proposed novel applications of virtual machine technology, such as Internet Suspend/Resume [25, 31] and transparent OS-level rollback and replay [13]. Unfortunately, current VMMs do not export enough functionality to budding developers of such applications, forcing them either to reverse engineer pieces of a black-box VMM, or to reimplement significant portions of a VMM. In this paper,
