The mobile virtualization technology provides a feasible way to improve the manageability and security for embedded systems. This paper presents an architecture named MobiXen to address these challenges. In the MobiXen, both Xen's physical memory space and virtual address space are shrunk as much as possible and thus Android owns ...

The increasing adoption of Graphic Process Unit (GPU) to computation-intensive workloads has stimulated a new computing paradigm called GPU cloud (e.g., Amazon's GPU Cloud), which necessitates the sharing of GPU resources to multiple tenants in a cloud. However, state-of-the-art GPU virtualization techniques such as gVirt still suffer from non-trivial performance ...

Virtual machine (VM) replication provides a software solution of for business continuity and disaster recovery through application-agnostic hardware fault tolerance by replicating the state of primary VM (PVM) to secondary VM (SVM) on a different physical node. Unfortunately, current VM replication approaches suffer from excessive overhead, which severely limit their ...

Today's commercial cloud service providers require the availability with an annual uptime percentage at least 99.95\%. While memory errors become norms instead of exceptions with the increasing memory's density and capacity in cloud applications. Thus, uncorrected errors from DRAM can be a significant source of system downtime. To address this ...

Virtualization poses new challenges to I/O performance. The single-root I/O virtualization (SR-IOV) standard allows an I/O device to be shared by multiple Virtual Machines (VMs), without losing performance. We propose a generic virtualization architecture for SR-IOV-capable devices, which can be implemented on multiple Virtual Machine Monitors (VMMs). With the support ...

Minimizing virtualization overhead and improving the reliability of virtual machines are challenging when establishing virtual machine cluster. Paravirtualization and hardware-assisted virtualization are two mainstream solutions for modern system virtualization. Hardware-assisted virtualization is superior in CPU and memory virtualization and becoming the leading solution, yet paravirtualization is still valuable in some ...

Live migration is one of the most important features of virtualization technology. With regard to recent virtualization techniques, performance of network I/O is critical. Current network I/O virtualization (e.g. Para-virtualized I/O, VMDq) has a significant performance gap with native network I/O. Pass-through network devices have near native performance, however, they ...

Virtualization is gaining popularity in cloud computing and has become the key enabling technology in cloud infrastructure. By replicating the virtual server state to multiple independent platforms, virtualization improves the reliability and availability of cloud systems. Unfortunately, existing Virtual Machine (VM) replication solutions were designed only for software virtualized I/O, ...

This paper describes a nested virtualization solution, which allows virtual machine monitor (VMM) with virtual machine to run within another virtual machine with low overhead. Previous nested virtualization solutions on x86 platform are mainly based on emulation, which result in poor performance and poor usability. We propose and implement NestCloud, ...

It is crucial to minimize virtualization overhead for virtual machine deployment. The conventional ×86 CPU is incapable of classical trap-and-emulate virtualization, leading that paravirtualization was the optimal virtualization strategy formerly. Since architectural extensions are introduced to support classical virtualization, hardware assisted virtualization becomes a competitive alternative method. Hardware assisted virtualization ...

Memory is the most frequently failing component that can cause system crash, which significantly affects the emerging data centers that are based on system virtualization (e.g., clouds). Such environment differs from previously studied large systems and thus poses renewed challenge to the reliability, availability, and serviceability (RAS) of today's production ...

High-quality I/O virtualization (that is, complete device semantics, full-feature set, close-to-native performance and real-time response) is critical to both server and client virtualizations. Existing solutions for I/O virtualization (e.g., full device emulation, paravirtualization and direct I/O) cannot meet the requirements of high-quality I/O virtualization due to high overheads, lack of ...

SR-IOV capable network devices offer the benefits of direct I/O throughput and reduced CPU utilization while greatly increasing the scalability and sharing capabilities of the device. SR-IOV allows the benefits of the paravirtualized driver's throughput increase and additional CPU usage reductions in HVMs (Hardware Virtual Machines). SR-IOV uses direct I/O ...
