摘要:
 虚拟化是构建云基础架构不可或缺的关键技术之一，它保证了云计算平台的高性能与高可用性，使云计算平台在实际应用中资源最大化、利润最大化。 Linux容器LXC( Linux containers)是一种内核虚拟化技术，可以提供轻量级的虚拟化，以便隔离进程和资源，而且不需要提供指令解释机制以及全虚拟化的其他复杂性。 LXC的实现需要Linux内核的支持，理解Cgroups和Namespace是分析LXC的关键。文中介绍了这两种内核机制，从原理上解释了如何隔离进程的资源，并分析了开源项目LXC容器启动的过程，然后通过实验来验证LXC在资源隔离和分配中所起的作用。随着LXC的更加完善，不久的将来轻量级虚拟化一定会推动PaaS的发展，被更广泛地运用在部署中。目前openstack已经支持基于LXC的docker部署，容器虚拟化技术也将会在云计算领域发挥越来越大的作用。
Abstract:
 Virtualization is one of the key technology to build cloud infrastructure,which ensures high performance and availability of cloud computing platform,in practical applications,it makes cloud computing platform to maximize resources and profits. Linux container virtualization technology can provide lightweight virtualization to isolate processes and resources. Unlike other full virtualization,it is not required to provide instruction interpretation mechanisms. LXC implementation needs the support of the Linux kernel, understanding Cgroups and Namespace is the key to analyze the LXC. Two mechanism based on kernel are introduced in this paper,which explains how to separate process from the resource,and analyzes the open source project LXC and starting process of container,and then through the experiment to verify the LXC’ s role in resource isolation and distribution. With the improvement of LXC,the near future lightweight vir-tualization will promote the development of PaaS,which will be more widely used in the deployment. Currently,openstack supports dock-er which is based LXC,Linux container will play an increasingly large role in cloud computing.
