Recently, Cloud Computing is getting considerable attentions not only as the technology trend but also the new business model. Virtualization plays an extremely important role in Cloud Computing. Server virtualization has been achieved using virtualization hypervisor software such as VMware, Xen, and KVM,etc. Virtual Machines (VMs) created by hypervisors share the same physical environment with each other. Network virtualization is made by virtually connecting each virtual machine to a port on the virtual switch, which can be implemented by software or hardware. In this paper, we review both software and hardware network virtualization techniques and present the integration of open-source hypervisor with software virtual switch, which provides cloud users a more elastic and secure network environment.
