When setting up servers it would often be nice to know, how these systems will react to hardware-failures such as a defect harddisk, random access memory, network interface or simple power failure. It would be nice to be able to test, if a system designed to continue delivering services even in the presence of faults will indeed do so. The authors have implemented UMLinux, a User Mode Linux which can be used for realistic fault injection experiments to help answer the questions. In order to be as close to reality as possible, the UMLinux implements kernel memory protection and runs the complete virtual machine (including operating system and all processes) as a single process on the (real) host.
