Abstract: This article introduces the current status of X86 architecture based paravirtualization technology and full-virtualization technology, especially for hardware assistant virtualization technology, proposes two systemic virtual machines, Denali and XEN, which support the paravirtualization technology. Then it discusses the development of full-virtualization technology. In the meantime, it presents the solution scheme that supports these two technologies, and focuses on the trends of development of virtualization technology and its usage model.
