Abstract
-This paper proposes live migration minimization scheme for reduce the number of migration a virtualization-based naval combat cluster. Irregular load pattern from multi nodes in the naval combat cluster can cause nodes overload. The proposed cluster system uses T(Type) & R(Rank) algorithm which are used to decide a node to be migrated for optimal resource allocation. In addition, this paper, proposes the load prediction scheme by defining overload probability based on computing resources such as CPU, memory and network I/O. Resource information of host and VM are collected frequently. Simulation results show that the proposed schemes reduce the number of migration trials and improve cluster stability efficiently.
