ABSTRACT:
Disclosed is a method and system to partition hardware resources between operating systems. A determination is made whether a first PCI resource attached to a line of a bus is to be sequestered to a service operating system (OS). If so, the first PCI resource is sequestered to the service OS. It is next determined whether at least one other PCI resource shares the same line of the bus as the sequestered first PCI resource. If so, the at least one other PCI resource is selected and sequestered to the service OS. The first PCI resource and the other sequestered PCI resource are then hidden from a subsequently loaded host OS.
