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.
