也许application virtualization可能是一个选择？微软有以下说法：
In a physical environment,every application depends on its OS for a range of services,including memory allocation,device drivers,and much more. Incompatibilities between an application and its operating system can be addressed by either server virtualization or presentation virtualization; but for incompatibilities between two applications installed on the same instance of an OS,you need Application Virtualization.
