Abstract
Various embodiments are generally directed to providing virtualization using relatively minimal processing and storage resources to enable concurrent isolated execution of multiple application routines in which one of the application routines is made visible at a time. An apparatus to virtualize an operating system includes a processor component, a visibility checker for execution by the processor component to make a visibility check call to a kernel routine to request an indication of whether an instance of a framework routine that comprises the visibility checker is visible, and resource access code of the instance for execution by the processor component to perform a resource access operation to access a hardware component based on the indication and on receipt of an application programming interface (API) call from an application routine that specifies an API function to access the hardware component. Other embodiments are described and claimed.
