Abstract
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.
