Abstract
One embodiment provides a system that processes an input/output (I/O) operation associated with a portable storage device. During operation, the system loads a virtual computing environment stored on the portable storage device into a host computer system coupled to the portable storage device. Next, the system intercepts the I/O operation from the virtual computing environment to the portable storage device. Finally, the system decouples the I/O operation from the virtual computing environment by processing the I/O operation independently of a representation of the I/O operation in the virtual computing environment.
