Getting 10 Gb/s From xen: Safe and Fast Device Access From Unprivileged Domains

The networking performance available to Virtual Machines VMs can be low due to the inefficiencies of transferring network packets between the host domain and guests. This can limit the application-level performance of VMs on a 10 Gb/s network. To improve network performance, the authors have created a "Virtualization aware" smart...

xen and Server Consolidation

Enterprises are witnessing a server sprawl as low cost x86 boxes make their way into datacenters. Application provisioning on dedicated servers and provisioning hardware capacity for peak loads have led to unprecedented server proliferation and abysmally low utilization. Virtualization technology has the potential to play a significant role in enabling...

Building a MAC-Based Security Architecture for the xen Open-Source Hypervisor

This paper presents the sHype hypervisor security architecture and examines in detail its mandatory access control facilities. While existing hypervisor security approaches aiming at high assurance have been proven useful for high-security environments that prioritize security over performance and code reuse, the approach aims at commercial security where near-zero performance...

Making Wide-Area, Multi-Site MPI Feasible Using xen VM

Although multi-site MPI execution has been criticized in the past as being "Impractical" due to limitations in network latency and bandwidth, the authors believe many of the obstacles can be overcome by various means for wider classes of applications than previously believed. The current work involves using Xen as the...

Harness the Power of Virtualization for Server Consolidation: xen-Based Virtualization With SUSE Linux Enterprise on AMD Processors With AMD Virtualization

Virtualization lets one to reduce the total number of servers by giving a person the ability to migrate multiple environments on different physical machines to individual virtual machines hosted on a single server. These virtual machines each run their own independent and self-contained operating systems and server applications. By consolidating...
