---A middle layer can solve most of problems
Here are some examples to show the advantage of virtualization
Guest operating system don’t need any modification and execute on VM just as it would on physical machine.
Completely decoupling the software from hardware
helps to provide complete isolation of applications
Not good performance. VM monitor have to provide an image of entire system, include virtual BIOS, virtual memory space, virtual devices.
Not supported by IA-32,or x86, architecture.
Any question about the ring?
This paper is published 2003 just after the Xen 1.0 released. By now,these future work have been completed!
