Getting 10 Gb/s From Xen: Safe and Fast Device Access From Unprivileged Domains
Overview 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 network adapter and modified Xen to allow direct, but safe, access to such adapters from guest operating systems. Networking overheads are reduced considerably, and the host domain is removed as a bottleneck, resulting in significantly improved performance. It describe the modifications to the Xen networking architecture that allow guest kernels direct - but secure - access to the networking hardware, whilst preserving support for migration.
