Hardware errors are no longer exceptions in modern cloud data centers. Although virtualization provides software failure isolation among different virtual machines (VM), the virtualization infrastructure including the hypervisor and privileged VMs remains vulnerable to hardware errors. What makes matters worse is that such errors are unlikely bounded by the virtualization boundary and may lead to...
Virtualization technology as the foundation of cloud computing provides many benefits in cost, security, and management, but all of them rely on the reliability of the underlying virtualization software - the hypervisor (or virtual machine monitor). Cloud data centers are built upon 10Ks to 100Ks commodity servers. Hardware errors in these large scale computer systems are not rare events. When hardware...
Cloud data centers leverage virtualization to share commodity hardware resources, where virtual machines (VMs) achieve fault isolation by containing VM failures within the virtualization boundary. However, hypervisor failure induced by soft errors will most likely affect multiple, if not all, VMs on a single physical host. Existing fault detection techniques are not well equipped to handle such hypervisor...
