In cloud computing with host virtualization, it is necessary to understand the queue of storage for disk requests due to the competition for the storage requirements of Virtual Machine (VM). In this paper, the authors address schemes, sequence and dynamic balance allocation, for handling the VM queue to access the virtual storage device. SimPy, python-based simulation tool is adopted to build the simulation models to get analytical data. The SimPy simulator incorporates the resource analyzing. Cloud computing has emerged as a promising approach to rent a large IT infrastructure on a short term pay-per-usage basis, but also as an important paradigm for accessing distributed computing resources.
