摘要： In one embodiment, a method for supporting address translation in a virtual-machine environment includes creating a guest translation data structure to be used by a guest operating system for address translation operations, creating an active translation data structure based on the guest translation data structure, and periodically modifying the content of the active translation data structure to conform to the content of the guest translations data structure. The content of the active translation data structure is used by a processor to cache address translations in a translation-lookaside buffer (TLB).

摘要： One embodiment of the invention is method for resolving address space conflicts between a virtual machine monitor and a guest operating system. The method includes allocating an address space for the operating system and an address space for the monitor. The method also includes mapping a portion of the monitor into the address space allocated for the operating system and the address space allocated for the monitor, and locating another portion of the monitor in the address space allocated for the monitor. The method also includes detecting that the operating system attempts to access a region occupied by the portion of the monitor within the address space allocated for the operating system, and relocating that portion of the monitor within that address space to allow the operating system to access the region previously occupied by that portion of the monitor.

摘要： Apparatus for double-sided imprint lithography of an apertured substrate comprises a pair of correspondingly apertured molds, a support for an assembly of the substrate and molds, and an alignment mechanism with radially movable elements for aligning the apertures of the molds and the substrate. The movable elements can be at least partially disposed in a spindle and can be removed radially outward by a conically tapered drive rod. Opposing surfaces of the substrate can then be imprinted in registration at the same time, preferably by fluid pressure imprint lithography.
