UMLinux - A Versatile SWIFI Tool

This tool presentation describes UMLinux, a versatile framework for testing the behavior of networked machines running the Linux operating system in the presence of faults. UMLinux can inject a variety of faults into the hardware of simulated machines, such as faults in the computing core or peripheral devices of a machine or faults in the network connecting the machines. The system under test, which may include several machines, as well as the faultand workload run on this system are configurable. UMLinux has a number of advantages over traditional SWIFI and simulation tools: speed, immunity of fault-injection and logging processes from the state of the machine into which the faults are injected and binary compatibility with real world data and programs.
