This paper deals with various virtual machine security mechanism in cloud environment where the authors can access virtual hard disk, virtual servers in pay as you go manner. It also explains about kernel attack, critical problem in virtualization and how the security architectures are used to solve that issue are explained in this paper. It is the survey of various cloud virtual machine architectures, advantages & disadvantages.
