FLoW-Linux: Virtualization distribution scheme for fault tolerant and system enhancement

The development of microkernel has sharply increased. One of the most successful microkernel implementation is L4. L4Linux is L4 version that is able to run virtualized Linux. We have also built our microkernel named FLoW. In this paper we described about our achievement in developing virtualized Linux on top of our FLoW microkernel. We implemented unique design about virtualizing more than one Linux. The idea is about creating more than one Linux to handle the requests made by user application about Linux system call. So every user application that requests the feature of Linux system call will be handled by more than one Linux Service. The result shows that there is an acceleration of processing time. The total CPU cycle used by user application in working with user request are less when having such mechanism. That means our mechanism successfully accelerate around 17% processing time of user application that request Linux system call from within our Linux Service that run on top of FLoW Microkernel. Then the system endurance testing resulted that our system is able to handle around 96 Linux system calls request almost at the same time without break.
