SUMMARY:Fault Tolerance using Live Execution Replay in Virtual Machines -

DESCRIPTION:This talk is about using virtual machines to achieve tolerance
  to hardware faults by replaying live execution. Our system consists of a 
 master virtual machine and a set of slaves which are at a synchronized sta
 te and execute the instructions independently of one another. The overall 
 output of the system is determined as a result of an voting process by the
  individual virtual machines. We use an instruction stream synchronizer to
  accurately transmit and execute the instruction on the set of VMs. The sy
 stem is still being built and is hence not yet evaluated. The talk is more
  about the experiences that we have had so far in building the system.
