With the integration of KVM and the paravirt_ops into the 2.6.20 kernel, Linux has now its own virtualization technology and is able to use the hardware virtualization features of recent CPUs from AMD and Intel of its own. In our talk we will give an overview of the existing virtualization approaches implemented by KVM, Xen and VMware and their advantages and disadvantages. Focusing on Linux we will show which approach KVM follows currently and how it uses the virtualization features of the processor for its tasks. By pointing out recent developments in KVM and Linux virtualization we will give an overview of the future direction KVM will go with paravirtualized drivers, a general paravirtualization API and how next generation processor features like Nested Paging will be used to simplify the software side of hypervisors in general.

Joerg Roedel studied computer science at the Technical University in Chemnitz, Germany. Since November 2006 he is working for AMD in the new founded Operating System Research Center department. His workplace is located in Dresden, Germany. From there he is working on the Linux side of virtualization and general optimization of Linux for current and upcoming AMD hardware. Currently his work focuses on KVM and IOMMU. His further interests include fast cryptography and the Linux networking stack.

Über den Autor André Przywara:

I studied Computer Engineering at the Technical University of Berlin. During the study I worked as a tutor for UNIX and CS related courses. My diploma thesis dealt with realtime Linux on a PowerPC-based embedded system. Afterwards I spent some time on bioinformatics and gave lectures before I got to AMD in Dresden. Here at the Operating System Research Center I work in the XEN team and focus on testing and QEMU issues.
