Systems and procedures bimodal device virtualization based on real hardware devices and idealizados

摘要

A Computer System, The Computer System comprising a Guest Operating System (112, 114), a virtual device (150) and a bimodal host Operating System (104)In the host operating system includes an implementation of Virtual Machine includes the guest operating system.In the guest Operating System comprises a First Controller (122, 122 ") that interacts with the Virtual Device bimodalIn this virtual Device implementation of bimodal is implemented in the Virtual Machine and the host Operating System comprises a Second driver (130)And wherein Said Second bimodal interacts with the Virtual device driver and selectively operates as a virtual hardware device in a First Mode (153) and as an inheritedIdealized virtual device in a Second High Performance Mode (154)In the Virtual hardware device in said First Legacy mode acts as a real device modeling of hardware and virtual device (132) The idealized in diCho Second High Performance mode is optimized for use in a Virtual Machine environment to not be a mere Reflection of physical hardware and not having to comply with a physical hardware designSico.
