This paper reports on improvements to Xen's networking performance resulting from the re-design and the re-implementation of certain aspects of its network virtualization and better support for advanced, hardware memory management features. This design remains compatible with the basic Xen 2.0 architecture of locating device drivers in a privileged driver domain that has direct access to the devices, and providing ordinary, unprivileged guest operating systems in guest domains access to the network through virtualized interfaces.
