Abstract:
Virtual host migration is an important aspect in today’s data centers for fault tolerance, system maintenance, server consolidation and high availability. Live virtual host migration within a traditional datacenter involves mobility and movement of virtual machine along their running services from one physical server to another with minimal downtime. As Software Defined Networking is a new paradigm which separates data plane and control plane for network devices and this separation helps in central management and supervision of expanding number of Virtual host through software based controller, so virtual host migration using SDN would be helpful in providing flexibility in today’s traditional datacenter as well. But security can be an issue in this migration process as movement of virtual host along with their running services may be comprised by an attacker who can launch attacks on confidentiality, integrity and mutual authentication during live migration process. Therefore, we have proposed and develop system architecture for secure live migration in datacenters using extended FIPS196 standard and hypervisors support. We have focused on virtual host migration security using open source technologies, with minimum changes in the existing workflows.
