云计算环境下的虚拟机快速克隆技术
Rapid virtual machine cloning in cloud computing environment.
摘要
Abstract
Virtual machine cloning is a key technology for cloud computing which helps to clone multiple VMs rapidly and distribute them on different physical hosts. The cloned VMs share the same initial state, and then run independently to provide services. With virtual machine cloning,cloud vendors can deploy system resources quickly and efficiently. This paper presents a method of fast VM cloning,which creates snapshots of virtual disk and memory of VM by copy-on-write technology.Then synchronization between parent VM and child VMs is done by multicast together with memory-on-demand mechanism.Experiment on C3(CAS Cloud Computing) platform shows that it achieves rapid VM cloning without interrupting the service of the source VM.关键词
