Abstract:
Cloud Computing is one of the leading technologies. As a solution to many of the challenges faced by Cloud providers, virtualization is employed in Cloud. Virtual machine migration is a tool to utilize virtualization well. In general, the term "virtualization" refers to the process of turning a hardware-bound entity into a software-based component. The end result of such procedure encapsulates an entity's logic and is given the name of Virtual Machine (VM). The main advantage of this technique is that multiple VMs can run on top of a single physical host, which can make resource utilization much more e_cient. Of particular interest are those VMs with high availability requirements, such as the ones deployed by cloud providers, given that they generate the need to minimize the downtime associated with routine operations. VMs can deal with availability constraints much more gracefully than their physical equivalents. While physical hosts have to be powered down for maintenance, the VMs that they serve can migrate to execute on other physical nodes. It is also common to migrate VMs when load balancing is needed in the physical plane. The process of migrating VMs without any perceptible downtime is known as Live Virtual Machine Migration and is the topic of this paper. This nontrivial problem has been studied extensively and popular hypervisors (e.g. Xen, VMware, OpenVZ) have now put reasonable solutions to practice. After covering the pre-copy and post-copy approaches to live VM migration, a variety of design decisions will be discussed along with their pros and cons. Having set the necessary theoretical background, a security-focused survey will be carried out, documenting the state-of-the-art in Live VM Migration exploits and countermeasures.
