Server virtualization is a technology of prime importance in contemporary data centers. Virtualization provides two key mechanisms, virtual instances and migration, that enable the maximization of the resource utilization to decrease the capital expenses in a data center. In this thesis, we identified and studied two contexts where traditional virtual instance migration falls short in providing the optimal tools to utilize at best the resource available in a cluster: idle virtual machines and largescale hypervisor upgrades.Idle virtual machines permanently lock the resources they are assigned only to await incoming user requests. Indeed, while they are most of the time idle, they cannot be shut down, which would release resources for more d...
