Abstract: Dynamic program analysis is decoupled from execution in virtual computer environments so that program analysis can be performed on a running computer program without affecting or perturbing the workload of the system on which the program is executing. Decoupled dynamic program analysis is enabled by separating execution and analysis into two tasks: (1) recording, where system execution is recorded with minimal interference, and (2) analysis, where the execution is replayed and analyzed.

Abstract: A virtualized computer system provides fault tolerant operation of a primary virtual machine. In one embodiment, this system includes a backup computer system that stores a snapshot of the primary virtual machine and a log file containing non-deterministic events occurring in the instruction stream of the primary virtual machine. The primary virtual machine periodically updates the snapshot and the log file. Upon a failure of the primary virtual machine, the backup computer can instantiate a failover backup virtual machine by consuming the stored snapshot and log file.
