Abstract
Various embodiments of the present invention are directed to efficient methods by which virtual-machine monitors can introduce instructions into guest-operating-system code. In one embodiment of the present invention, the virtual-machine monitor builds instructions dynamically, at insertion time, using specified values for fields within the instruction. In one embodiment of the present invention, the instructions and instruction field values are stored in an instruction-block-representing data structure.
