Mitigating Virtualization Failures Through Migration to a Co-Located Hypervisor
Cerveira, Frederico; Barbosa, Raul; Madeira, HenriqueMany organizations are moving their systems to the cloud, where providers consolidate multiple clients using virtualization, which creates challenges to business-critical applications. Research has shown that hypervisors fail, often causing common-mode failures that may abruptly disrupt dozens of virtual machines simultaneously.
