云计算目前在国内和国际的发展可谓“如火如荼”，云手机、云电视、云生活铺天盖地的涌现在大家面前，同时我们也看到大量的云计算公司应运而生，显而易见，云计算已经成为IT行业的大趋势。随着云计算的发展，越来越多的人开始对基础设施即服务(IAAS)感兴趣。调查显示有51%的人正在使用IAAS，66%的人会在未来五年内开始使用IAAS。Rackspace和美国宇航局合作推出的开源云管理平台 OpenStack 目前在基础设施即服务领域处于领先地位。但是由于OpenStack推出时间不长，有关其工作原理的研究较少有人涉及。本文研究了该平台中的虚拟机启动过程，以期能对该过程加以改进，进而降低云的运营和管理成本。

Cloud computing grow vigorously recently both at home and abroad, Cloudphone, CloudTV and Cloudlife come to the fore of everyone. At the same time, we can see more and more cloud companies. Obviously, cloud computing is becoming the megatrends of IT industry. With the development of cloud computing, an increasing number of people become interested in the Infrastructure As A Service(IAAS). That says that 51%of people are using IAAS and more than 66% will begin to use it in the next five years. Opensource cloud computing platform OpenStack released by Rackspace and NASA now leads the way in IAAS. However, there is little research on how it works because it has been lately released. In this paper, we researched on the flow of virtual machine launching in OpenStack. We want to improve this process in the future and so as to lower the cost of operation and management of the cloud.
