A novel mechanism for rapid provisioning virtual machines of cloud services

Cost down and energy saving are concerned issues in recent years. As a result, cloud computing services for enterprises and persons have been increasing. As for cloud Infrastructure-as-a Service (IaaS), virtual machines (VM) in "cloud" are also starting to replace the original local hosts commonly. Meeting consumers\´ IaaS requirements with different computing powers, different operating systems, and different quantities in a fast and on-demand fashion has become an important issue for cloud service providers. For Chunghwa Telecom\´s IaaS service, branded "hicloud", we propose a novel mechanism for rapid provisioning a variety of virtual machines. We illustrate the end-to-end IaaS fulfillment process, kernel VM Pool Management and multi-threading VM activation mechanism for fast VM provisioning in this paper in detail.
