This dissertation was carried out in order to investigate the current methods for securing live virtual machine migration and to contribute to the current frameworks that currently exist. The Live migration of virtual machines is fundamental component of cloud computing. In recent years, researchers have discussed frameworks and methodologies to secure the process of live virtual machine migration. However the majority of research that is carried out to date has focused on the performance and not on security. The research that we have undertaken focuses on the security of virtual machine during migration. To fulfill this we investigated two popular open source hypervisors XEN and KVM. We found security flaws in each system and have proposed securing the live migration process by using encryption, intrusion detection systems, role based access control and firewall rules. We recommend that XEN is the more secure of the two systems available.
