This paper presents the architecture for a self-stabilizing hypervisor able to recover itself in the presence of Byzantine faults regardless of the state it is currently in. Our architecture is applicable to wide variety of underlying hardware and software and does not require augmenting computers with special hardware. The actions representing defense and recovery strategies can be specified by a...
In this paper we present a technique for detecting information leaked from the hypervisor to the guest OS via statistical analysis of the amount of time required to map and unmap a page in memory. Analysis of these timings allows a guest to determine the number of co-located VMs on the same physical hardware as well as determine whether or not the VM is being monitored by Virtual Machine Introspection.
Virtualization is a key technique to make anenvironment easier to manage in terms of resource allocation.MapReduce is a programming model that provides anabstraction to perform distributed computation for large datasets. Hadoop is a well-known framework that offers an opensourceimplementation for this model. Combining Hadoop andvirtualization techniques in cloud-computing environments canunveil great...
Cloud computing is a computing style where resource providers can offer on-demand services in a transparent way and clients usually pay as they go. It introduces a new level of flexibility and scalability for IT users addressing challenges such as the rapid change in IT and the need to reduce cost and time of infrastructure management. However, to be able to offer QoS guarantees without limiting the...
