Xen 3

von Steven Hand (University of Cambridge)

Samstag, 06.05.2006, Saal 7, 13:30-15:00 Uhr

Xen 3 was released in December 2005, bringing new features such as support for SMP guest operating systems, PAE and x86_64, initial support for IA64, and support for CPU hardware virtualization extensions (VT/SVM). In this talk I'll provide an overview of Xen, discuss its architecture, and present some key technical details about how it works. In particular I'll cover how Xen's paravirtualizes the CPU, physical memory, the MMU, and I/O devices, hopefully touching on address space layout, hypercalls, event channels, M2P and P2M, batched- and writable-pagetables, grant tables and devices channels. I'll briefly discuss the tool-stack, focusing on the core components of libxc, xenbus and xenstore. And, time permitting, I'll talk about HVM (the combined VT/SVM layer), live migration, and ongoing work.
