Then, it examines various schemes of VM migration and discusses research directions in virtualization security. The ultimate goal is to provide a deep understanding of the developments and the future directions regarding virtualized environments migration primitive. Virtual network migration is explained, and the chapter also presents a proposal for migrating virtual routers without packet losses. It describes the main security issues of machine virtualization, and exposes the main security requirements for a secure virtualization platform. Finally, it focuses on securing VM migration and also highlights security issues that affect cloud computing environment based on machine virtualization.
