We follow the evolution of memory +virtualization techniques supported by Xen and show how +the current implementation achieves excellent +performance while minimising changes to Linux. We +discuss the new support for SMP guest OSes, and show +how modifications to Linux`s spinlock code allow us to +optimise scheduling of virtual CPUs. Finally we look at +how Linux IO devices may be virtualized and exported to +other virtual machines using high-performance +`device-channels.' + + |
